Zero-Floor Manager review — strong execution. Direction approved; pre-ready checklist outstanding.

Diff matches the brief's two surfaces precisely with manager lean (a) applied:

✅ Surface 1 (TestRunner ExecuteCommand match arm at test_runner.rs:450): added; calls eval_execute_command which compiles claim source, parses payload, spawns via shared evaluate_execute_command_exit_code.
✅ Surface 2 (M1.5 testgen harness): retired shell_exit_matches_allowlisted allowlist + parse_shell_predicate_payload/list_string_literals local helpers; deduplicated into shared canonical functions in test_runner.rs.
✅ Manager lean (a): parse_execute_command_fields + evaluate_execute_command_exit_code are pub fns shared by TestRunner and M1.5 harness — single canonical path, zero parallel-implementation debt. Exactly the structural choice the brief flagged as discipline-critical.
✅ Hermetic property narrowing applied verbatim: M1.5 helper comment now reads "ExecuteCommand is the declared host-process spawn boundary: everything else in this harness stays data-only" — matches the cascade framing.
✅ Distinguishable error variants: spawn-error / signal-killed (no exit code) / exit-mismatch all return distinct ClaimResult::Fail messages with structured prefixes.
✅ Int exit-code handling: output.status.code().map(i64::from) cleanly widens i32 → i64 (substrate Int = i64). Resolved without STOP-AND-ESCALATE — defensible engineering.
✅ End-to-end boundary-test migration: tests/dag/t_pb_b_1_execute_command_boundary.dag + t_pb_b_1_dag_runner_test.rs integration test. Migration receipt explicitly cites m1_4_emit_python_test::python_stdout as the class-5 boundary pattern being structurally paralleled. Used sh/echo/true instead of python3 to avoid CPython requirement in CI — good operational discipline.
✅ TESTING.md callout updated reflecting landed extension; design-pure-bootstrap-zero.md capability-state callout updated; both internally consistent post-update.

Two minor observations (non-blocking)

Cross-platform command coverage: brief revision specified true/false for cross-platform smoke. Diff includes true/false AND sh -c "exit 0" AND echo hi. true/false are POSIX-standard; sh -c and echo are POSIX-shell-dependent (PowerShell builtin divergence on Windows). If Windows CI is in scope, the sh/echo cases would fail — the true/false smoke is platform-safe, the others are bonus coverage. Manager-call: probably fine since CI is Unix-only, but worth confirming Windows CI scope before merge. If Windows is in scope, consider gating sh/echo cases behind #[cfg(unix)] or moving to tests/dag files that runners can platform-skip.
Diff size sanity: 289/-75 across 7 files. The 75 deletions are mostly the M1.5 harness's inlined parse helpers being replaced by shared canonical versions — actual additive surface is closer to ~150 LOC. Reasonable for an M-L sized lane.

Pre-ready checklist (per brief)

cargo test --workspace --exclude v2-compiler-tests passes
cargo clippy --all-targets -- -D warnings clean
cargo fmt --all --check clean
DB-8 self_host_fixed_point converges bit-identically
Smoke + capability + boundary-migration tests all pass

CI is skipping while draft. Mark ready when checklist is green; on merge I'll signal Director that T-PB-B's PB-Runtime dependency clears (per brief's Reporting → On merge clause).

Findings

None blocking. One worth surfacing:

**docs/briefs/pb-runtime-execute-command-worker.md:39 — "Boundary-test migration smoke" checkbox is checked, but the receipt at src/v3/compiler/tests/dag/t_pb_b_1_execute_command_boundary.dag:1-40 uses true/sh/echo rather than porting an existing rustc/python3/go boundary test. The brief's example explicitly suggested a real rustc/python invocation; the diff itself acknowledges this in TESTING.md:195 ("Residual bulk migration … remains its own work item"). The cascade's empirical claim — "a real Rust-side boundary test ported end-to-end" — is therefore demonstrated structurally (same std::process spawn shape) rather than empirically (an actual external toolchain invocation in CI). Non-blocking, but the acceptance checkbox arguably overclaims; either uncheck and call it deferred, or add one real port (the m1_4_emit_python_test::python_stdout referenced in the comment is the obvious candidate, gated behind --ignored if CPython-on-CI is the concern).

Exploratory observations

eval_execute_command (test_runner.rs:1019-1042) compiles claim.source purely as a precondition gate, then discards the Dag. Other predicates use the compiled output; here it's a pure "source must compile cleanly" check. That matches the M1.5 harness's gate, so it's consistent — just worth noting that under ExecuteCommand the claim source is otherwise inert. The t_pb_b_1_execute_command_boundary.dag claims all carry source: "let marker: Int = 1" precisely because of this; that's a small smell of vestigial coupling, not a violation.
Hermeticity assumption: the new ClaimResult::Pass paths assume true, sh, echo are on PATH. POSIX-fine, Windows-hostile. If Windows-CI is ever in scope, these will spawn-error. Probably fine for now given the project's targets.

Verdict

APPROVE_WITH_COMMENTS — Implementation is clean: shared parse_execute_command_fields + evaluate_execute_command_exit_code honor the brief's "single execution path" lean, fail messages distinguish spawn-error / signal / exit-mismatch, M1.5 allowlist + fail-closed panic are correctly retired, and three runner-level tests cover pass/mismatch/spawn-error. No invariant or modeling-discipline violation in the diff. Main comment is just that the "boundary-test migration" acceptance bullet is structurally — not empirically — satisfied; worth reconciling the checkbox with the deferred-bulk caveat.

Thinking: 125s wall

Findings

src/v3/compiler/src/test_runner.rs:343 violates P3/P4 fail-closed/decidability: arbitrary ExecuteCommand now uses Command::output() with no timeout and buffers stdout/stderr even though only exit code is asserted. A checked-in claim can hang CI or exhaust memory instead of producing a typed ClaimResult::Fail.
docs/briefs/pb-runtime-execute-command-worker.md:86 / src/v3/compiler/tests/integration/t_pb_b_1_dag_runner_test.rs:93 violate P1 documentation-live-state / P5 progress discipline: the checklist marks “one existing Rust-side boundary test ports” complete, but the landed suite explicitly substitutes sh/echo/true for the m1_4_emit_python_test::python_stdout pattern. That is a capability smoke, not a port of an existing boundary test.

Verdict: REQUEST_CHANGES. The shared parser/evaluator shape is clean, but the unbounded process execution boundary needs a cap or explicit escalation before this can be treated as landed runner support.

BLOCKING (1)

Root Cause

docs/briefs/pb-runtime-execute-command-worker.md PB-Runtime acceptance marks arbitrary process execution complete without resolving its own timeout/sandbox/resource-cap STOP condition → add a bounded execution policy and return ClaimResult::Fail on timeout/resource breach before declaring the lane landed.

Non-blocking — Strengths

src/v3/compiler/src/test_runner.rs The Rust TestRunner and M1.5 harness now share the ExecuteCommand parser/evaluator path, avoiding a parallel command-shape implementation.

ROADMAP — Incomplete

T-PB-B PB-Runtime dependency: ROADMAP still says arbitrary-command runner support is deferred to PB-Runtime, so the status authority needs updating if this PR is intended as the closure receipt.

⚠️ Bounded execution needs to land before arbitrary ExecuteCommand can be treated as complete.

Commit: e77eb788 · Trigger: schedule
Thinking: 41s wall

Findings: none blocking.

Minor observations (non-blocking):

evaluate_execute_command_exit_code_with_wall_time uses a 20ms polling loop. After kill, child.wait() is unbounded — relying on the kernel to reap a SIGKILL'd child is fine in practice on Unix, but worth noting that "fail-closed on timeout" still depends on wait() returning. Not a discipline violation, just an honest gap.
eval_execute_command re-runs compile_to_dag(&claim.source, &claim.file_name) per claim — every other arm in the file does the same compile-gate dance, so this is consistent (not a duplication finding), but a future cleanup could lift the compile-gate out of each arm. Out of scope here.
t_pb_b_1_execute_command_boundary.dag depends on POSIX sh/echo/true on PATH; the comment header calls this out explicitly and t_pb_b_1_dag_runner_test.rs:91-95 repeats the caveat. Acceptable given CI is Linux-only; the documented dissolution trigger is "if a Windows CI job is added, gate or trim." Tracked-debt shape is good.

Doc/code stay in sync: TESTING.md capability callout, the brief's "Landed lane receipt," design-pure-bootstrap-zero.md, and test_runner.rs all cite the same EXECUTE_COMMAND_WALL_TIMEOUT + null stdio + shared evaluate_execute_command_exit_code path. M1.5 harness now delegates into the same path — one authority, two readers (TestRunner and the testgen harness), which is the principled shape.

The acceptance checklist's downgrade of the "empirical class-5 port" box to "deferred" with a candid Api-review #792, 2026-04-25: prior checkbox overclaimed; reconciled to structural vs empirical annotation is honest scope-narrowing, not scope-creep, and matches what the diff actually delivers.

Verdict: APPROVE — bounded execution policy (wall timeout + null stdio + distinguishable Fail variants) closes the prior STOP-AND-ESCALATE condition; tests cover pass / exit-mismatch / spawn-error / timeout; doc updates are consistent with code; single shared std::process path satisfies the brief's "both surfaces share execution mechanism" acceptance.

Findings

BLOCKING: src/v3/compiler/src/test_runner.rs:390 watches only the direct Child, and src/v3/compiler/src/test_runner.rs:395 kills only that child on timeout. With arbitrary commands now allowed, a claim like sh -c 'sleep 600 &' can exit 0 before the deadline, return Pass, and leave unbounded descendant work running. That violates the P3/P4 bounded/fail-closed claim this PR makes for ExecuteCommand.
NON-BLOCKING: src/v3/compiler/tests/integration/m1_5_testgen_test.rs:252 collapses every ClaimResult::Fail into plain false. That loses the distinguishable spawn-error/timeout/exit-mismatch carrier promised in TESTING.md:195, so M1.5 can treat infrastructure failures as an ordinary false predicate.

Verdict: REQUEST_CHANGES. The main runner needs process-tree/job-control enforcement, a sandbox, or a tracked scaffold instead of declaring the bounded execution lane closed. I ran cargo test --manifest-path src/v3/compiler/Cargo.toml --test integration test_runner_evaluates_execute_command_pass_and_fail; it passed, but it does not cover the descendant-process bypass.

1. Story of the diff

This PR lands the PB-Runtime ExecuteCommand runner path that the docs previously described as foundation-only. The core mechanism is a shared test_runner.rs parser/executor: parse_execute_command_fields accepts either lowered record or positional payloads, and evaluate_execute_command_exit_code becomes the single host-process execution path reused by both the Rust TestRunner and the M1.5 testgen harness. The main runner now dispatches TestPredicate::ExecuteCommand, requires the claim source to compile cleanly first, then evaluates command/args/expected-exit as a ClaimResult.

The tests and docs are updated to treat this as landed capability: M1.5 retires the previous tautological allowlist, the T-PB-B-1 .dag suite adds true, sh -c exit 0, and echo hi examples, and the integration tests cover pass, exit-code mismatch, and spawn-error classification. The broad direction is good: the diff collapses the two previous evaluator shapes into one shared function and updates the zero-floor / testing docs so the remaining Rust boundary-test migration is described as bulk follow-up rather than a runner gap.

2. Invariant categories

LAYER MODEL (substrate vs implementation).

Compliant — this is implementation/test-runner work, not a Dag substrate mutation: the new code consumes existing lowered FieldValue payloads via parse_execute_command_fields at src/v3/compiler/src/test_runner.rs:280 rather than adding new Dag-resident state or a parallel substrate representation.

INVARIANTS.md + modeling-discipline.md.

Finding — BLOCKING, P4 bounded forward execution / P3 fail-closed: src/v3/compiler/src/test_runner.rs:343 adds let output = match Command::new(command).args(args).output() {. Because this is now the arbitrary-command .dag boundary, an accepted ExecuteCommand("sh", ["-c", "sleep 999999"], 0) can block the runner indefinitely, and .output() also captures stdout/stderr without a size bound even though the predicate only needs exit status. That is not fail-closed: non-termination or unbounded output becomes a hung/possibly memory-growing test process instead of a typed ClaimResult::Fail. Add a bounded execution path, for example a default timeout plus killing/reaping the child on expiry and either discard or cap stdout/stderr, then surface timeout/output-limit cases as distinguishable ClaimResult::Fail.

CODING.md.

Compliant — the shared implementation follows the data + free-functions style: parse_execute_command_fields at src/v3/compiler/src/test_runner.rs:280 and evaluate_execute_command_exit_code at src/v3/compiler/src/test_runner.rs:338 are explicit-input functions, and the runner’s method only stitches claim compilation, payload parsing, and evaluation together at src/v3/compiler/src/test_runner.rs:1022-1043.

TESTING.md.

Finding — same blocking boundary needs a regression: the added tests cover success/mismatch and spawn-error behavior (src/v3/compiler/tests/integration/test_runner_test.rs:303 and src/v3/compiler/tests/integration/test_runner_test.rs:345), plus the .dag runner smoke at src/v3/compiler/tests/integration/t_pb_b_1_dag_runner_test.rs:96. They do not cover the new boundary’s finite-execution contract because the implementation has no timeout at src/v3/compiler/src/test_runner.rs:343. Once bounded execution is added, include a behavior-driven test proving timeout is reported as ClaimResult::Fail without hanging the suite.

LOCKED DESIGN DECISIONS.

Compliant — the PR explicitly updates the zero-floor / PB-Runtime design state rather than silently diverging: docs/design-pure-bootstrap-zero.md:138 now states the runner extension is landed and names the remaining work as bulk migration of older class-5 boundary tests.

TRACKED vs UNTRACKED DEBT.

Compliant — the residual migration debt is documented and bounded: TESTING.md:195 says older Rust Command::new("rustc" | "python3" | …) boundary tests remain a ROADMAP work item, while the landed receipt is the T-PB-B-1 .dag boundary example. That is a tracked bridge, not an unbounded hidden TODO.

3. Verdict

REQUEST_CHANGES

The shared evaluator shape and test coverage are mostly solid, but the new arbitrary host-process boundary must be finite before it becomes the declared .dag test path. Add timeout/kill behavior and a timeout regression, then this looks approvable.

Commit: 25c21fc9 · Trigger: schedule
Thinking: 46s wall

Findings

Non-blocking — & policy is too broad in practice. src/v3/compiler/src/test_runner.rs:296 (the args[1].contains('&') check in reject_unbounded_shell_background) treats any & as background. That includes && (logical AND), ||... & deliberately, file-descriptor redirects like 2>&1, and command &> file. A claim like ExecuteCommand("sh", ["-c", "foo && bar"], 0) will be rejected with a "background" diagnostic that's literally false. Fail-closed is consistent with discipline, but the message will mislead triage. Tightening to a regex for unquoted trailing & or simply documenting "any & in shell -c is rejected, including && and 2>&1" in the diagnostic text would resolve. (CODING.md — diagnostics should be precise; not an INVARIANTS violation.)
Non-blocking — wait loop is a 20ms-granularity busy-poll. test_runner.rs:396-413 polls try_wait every 20ms. Functionally correct and the timeout phrasing test (0.15 exact) only works because the deadline check happens before sleep. A wait_timeout-style API or a one-shot reaper thread would avoid the sleep granularity, but wait_timeout isn't in std. Acceptable as-is for this lane; flag only because future tightening of EXECUTE_COMMAND_WALL_TIMEOUT toward sub-second values would make the granularity visible.
Observation, not a finding. The deferred "Empirical class-5 port" checkbox in docs/briefs/pb-runtime-execute-command-worker.md:107 has a named trigger ("bulk migration of older Rust Command::new("rustc"|"python3"|…) boundary tests"), bounded scope (T-PB-B work item), and documentation. That's a tracked-debt scaffold, not unreviewed debt — accept.

Single-authority on parsing is preserved: m1_5_testgen_test.rs now imports parse_execute_command_fields and evaluate_execute_command_exit_code rather than carrying parallel copies. Good — that was the lane's "one canonical path" requirement and it's met.

Verdict

APPROVE_WITH_COMMENTS — Implementation-layer change, well-scoped to test_runner.rs + harness, single shared execution path, bounded policy with distinguishable failure modes, documented timeout cap. No INVARIANTS, modeling-discipline, or substrate concerns. The & heuristic and busy-poll are real but don't block; the deferred empirical port is properly tracked debt.

Findings

BLOCKING: src/v3/compiler/src/test_runner.rs:483 returns Pass as soon as the direct child exits with the expected code, while the only descendant escape check is the narrow literal shell-& filter at src/v3/compiler/src/test_runner.rs:361. An ExecuteCommand can spawn a child/grandchild and exit 0, leaving unbounded work running after the claim passes. That violates INVARIANTS P4 bounded execution and P3 fail-closed behavior for this new host boundary; the carve-out at src/v3/compiler/src/test_runner.rs:425 is not enough because this PR advertises the runner as bounded.

Verdict: REQUEST_CHANGES. The shared runner path and typed failure modes are directionally clean, and targeted execute_command tests pass, but the new boundary still admits passing claims that leave unbounded descendant processes behind.

Findings

src/v3/compiler/tests/integration/test_runner_test.rs:970 — test_runner_execute_command_spawn_error_is_distinguishable asserts msg.contains("spawn error"), but on Linux the runner wraps every command in unshare(1) -c -f -p -- <command>. Two outcomes on Linux, neither produces the expected substring:
1. unshare is installed (default util-linux). Command::spawn() succeeds — Rust never sees an OS-level exec error; the missing inner binary just makes unshare exit non-zero (typically 127), routing through the exit-code mismatch arm in test_runner.rs:493 whose message says "exit code mismatch", not "spawn error".
2. unshare itself fails to spawn — the Linux branch in test_runner.rs:455-460 formats "failed to start Linux unshare(1) -c -f -psandbox before{command}...", again without the substring "spawn error".
t_pb_b_1_dag_runner_test.rs:14 and the brief explicitly state CI is Linux-only (ubicloud-standard-2), so this test will fail on the very CI it's written for. The acceptance-checkbox claim that cargo test --workspace passes is therefore suspect; either the test is never run on Linux, or the assertion needs to also accept the unshare-mediated "exit code mismatch" / sandbox-startup messages. Recommend either (a) gate this test #[cfg(not(target_os = "linux"))] and add a Linux variant that asserts the unshare-exit-127 shape, or (b) widen the assertion to accept any of the three distinguishable triage strings. (TESTING.md: tests must be hermetic and behavior-driven; an environment-dependent assertion fails that bar.)
src/v3/compiler/src/test_runner.rs:313-330 (non-blocking, exploratory) — shell_dash_c_may_start_background_after_eliding_artifacts will false-positive on quoted/escaped ampersands like sh -c 'echo "&"' or sh -c 'echo \&', since elision doesn't model quoting. The doc-comment on reject_unbounded_shell_background is honest about being a heuristic and the bias is fail-closed (forces user to rephrase), so this is acceptable as-is — but worth a one-line acknowledgment in the rustdoc that quoted & is a known false-reject.

Verdict

REQUEST_CHANGES — the code itself looks careful and well-documented (bounded execution, null stdio, Linux PID-namespace wrap, distinguishable Fail messages — all aligned with the brief's P3/P4 framing and the modeling-discipline fail-closed posture). But the test_runner_execute_command_spawn_error_is_distinguishable assertion is incompatible with the Linux unshare wrapper added in this same PR. Fix the test (gate or widen), then this is an APPROVE.

Exploratory observations

The duplicated extraction logic that used to live in m1_5_testgen_test.rs is now consolidated into parse_execute_command_fields in test_runner.rs and shared — that's a nice "two readers, one source" move and cleanly retires the prior tautology allowlist.
EXECUTE_COMMAND_WALL_TIMEOUT is a pub const with no per-claim override. The doc-comment names this as policy; reasonable scaffold. Bounded + named, so qualifies as tracked debt rather than a violation.
Adding a libc dependency to v3-compiler is the first non-stdlib runtime dep on this crate (Cargo.toml comment previously said "Zero dependencies at M0.1"); the diff updates the comment honestly. Worth keeping an eye on future creep, but this single Unix-gated dep is justifiable for setpgid / kill(pgrp).

Findings

BLOCKING: src/v3/compiler/src/test_runner.rs wraps Linux execution in unshare, but src/v3/compiler/src/test_runner.rs compares that wrapper’s exit code directly to expect_exit_code. If unshare fails before execing the logical command, e.g. EPERM in a default container, a claim expecting exit 1 can incorrectly pass even though the command never ran. That violates INVARIANTS P3 / fail-closed: sandbox/setup failure must be a typed failure independent of the expected program exit code.

Verdict: REQUEST_CHANGES. The implementation is otherwise narrowly scoped, but the Linux wrapper currently lets boundary setup failure masquerade as a valid command result. I ran the targeted spawn-error test locally via cargo test -p v3-compiler --test integration test_runner_execute_command_spawn_error_is_distinguishable -- --nocapture; it passed on this non-Linux path, so the concern is specifically the added Linux unshare path.

BLOCKING (1)

Root Cause

src/v3/compiler/src/test_runner.rs unshare EPERM is only handled when spawning unshare itself fails, not when unshare starts and then reports setup failure on stderr → retry build_execute_command_process on detected permission/setup failure or stop documenting the fallback.

Non-blocking — Strengths

src/v3/compiler/src/test_runner.rs The Rust TestRunner and M1.5 harness now share parse/evaluate helpers for ExecuteCommand, avoiding a parallel command-shape implementation.

ROADMAP — Verified

T-PB-B: ROADMAP now distinguishes the PB-Runtime runner enabler from the remaining bulk migration of legacy boundary tests.

⚠️ The implementation is close, but the documented restricted-Linux fallback does not actually execute on the common unshare-starts-then-EPERM path.

TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens."

The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

* docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46af caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14).

The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b03 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e691.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d1. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189 (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656b partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be31) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be31 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa9 Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b13 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

…strate Pass program (#814) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46af caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): extend cascade across THESIS.md + sibling authorities Resolves claude REQUEST_CHANGES at sha fed6b03 — atomic-cascade self-violation. The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b03 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e691.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved.

Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656b partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be31) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be31 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa9 Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close BLOCKING — P2 stale, ExecuteCommand landed via #792 Resolves codex inline BLOCKING at sha 191be31 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:150. Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex non-blocking — capacity-table P2 framing stale Resolves codex non-blocking finding at sha bcac41b on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:270. Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b13 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

…la tighten (post-#814 carry-forward) (#815) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46af caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline.

The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing.

Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e691.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority.

All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d1. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189 (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656b partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be31) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be31 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa9 Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq).

Two coordinated fixes: 1. §Read first cites src/v3/std/substrate.dag (live .dag substrate authority) and src/v3/spec/v3_l1.dag:69 (DeclarationRef sentinel meta-type — already exists with consumers in verification.dag, emit_model.dag, python.dag). 2. Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom. Acceptance + sub-brief dispatch order updated to reflect B4.1's consumer-migration shape. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): B4 — tighten Phase 1 umbrella sentence The umbrella 'Land the typed carriers into src/v3/std/' framing was stale after f52e2ce's reframe of #1 to consumer-migration.

…ost-#815 follow-up) (#816) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46af caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): extend cascade across THESIS.md + sibling authorities Resolves claude REQUEST_CHANGES at sha fed6b03 — atomic-cascade self-violation. The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b03 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e691.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103f on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d1. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189 (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656b partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be31) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be31 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa9 Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex non-blocking — capacity-table P2 framing stale Resolves codex non-blocking finding at sha bcac41b on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:270. Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b13 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

Also removed 'typed substrate carriers' from the vocabulary list — substrate carriers are defined using the vocabulary, not part of it. Added a clarifying note that B4's carriers (DeclarationRef, fold-shape, emit-helper, extdeps-fixture-set) are typed declarations composed from the vocabulary, not vocabulary extensions.

Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

…4 precedent (rev. softening) (#818) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46af caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work.

The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b03 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e691.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch.

Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections.

Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved.

Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed.

Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656b partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be31) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be31 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa9 Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq).

All four are parallel-dispatchable Day-1 once R1 Closure Manager spawns; sized S or smaller per the manager brief. ## R1C-B — T-P0 fixtures (S; 3 gates) - p0_repeat_string_correct (Day-1, DB-15 schema): authored immediately - p0_no_fabrication_sentinel (ext): audit predicate shape; possibly blocks on R1C-A - p0_rest_ops_aligned (ext): audit predicate shape; possibly blocks on R1C-A Branch on audit per gate; bundle PRs if all DB-15-suffices, split if any blocks on R1C-A schema landing. ## R1C-C — T-Sub sub_type_alias_where_lowers fixture (XS; 1 gate) PR #703 already landed the feature with test_db11_type_alias_where_* integration receipts. Brief authors the .dag wrapper; predicate likely Compiles on a fixture program exercising type-alias where lowering. Single PR; dispatchable Day-1. ## R1C-E — T-Emit .dag TestClaim wrappers (S; 3 gates) PB-Runtime ExecuteCommand (PR #792) is the runner enabler. Three gates: - emit_rust_fixtures_rustc_green: ExecuteCommand running rustc on emitted output - emit_generic_bounds_survive: audit-decided shape (ExecuteCommand+grep or structural) - emit_omni_demo_fixtures_green: multi-target; ForAllTargets quantifier may need R1C-A schema, OR can be expressed as 3 ExecuteCommand claims (1 per target) STOP if ForAllTargets needed and not in scope; STOP if PR #792 ExecuteCommand runner doesn't cover the bounded-execution shape. ## R1C-F — T-Demo demo_user_authored_lens_rejects_violating_program (S; 1 gate) Built on T-LensAPI user_authored_lens_compiles (GREEN). Three components: - ~20-line user-authored lens in .dag (e.g., "max external HTTP calls per workflow" per THESIS canonical example) - Violating program (~10-20 lines) - TestClaim with FailsWithDiagnostic predicate (asserts lens rejects violator) Demo artifact also authored per docs/r2-structure.md §"Demo discipline". ## Discipline anchors applied - feedback_construction_over_ratchets — fixtures ground in observable behavior (compiles / output / exit-code), not parallel asserts - feedback_audit_adjacent_authority_first — every brief mandates audit step before authoring (pick predicate / pick lens example / pick path) - All four briefs cite docs/escalation-paths.md as escalation discipline authority ## Out of scope - R1C-A T-TestGen schema extensions worker brief (M; meatier; authored separately) - R1C-D T-PB census-as-.dag worker brief (M-L; meatier; gated on R1C-A; authored separately) - Implementation of any of these briefs (worker dispatch happens at R1 Closure Manager spawn) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

#836) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46afe caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): extend cascade across THESIS.md + sibling authorities Resolves claude REQUEST_CHANGES at sha fed6b032 — atomic-cascade self-violation. The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b032 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e6916d.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a1 (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103fad on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103fa on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d169. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189a (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79a on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656bbe partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be310b) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be310 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa95e Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b1318 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

Eight surface sites dissolve via four substrate carriers (DeclarationRef, structural fold-shape carrier, structural emit-helper carrier, structural extdeps-fixture-set carrier).

Replaced with the canonical 6 (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) per docs/thesis/the-substrate-two-coordinated-shapes.md §'The vocabulary closes here'. Also removed 'typed substrate carriers' from the vocabulary list — substrate carriers are defined using the vocabulary, not part of it. Added a clarifying note that B4's carriers (DeclarationRef, fold-shape, emit-helper, extdeps-fixture-set) are typed declarations composed from the vocabulary, not vocabulary extensions.

Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

Likely friction point: brief Slice step 4 asks for a unit test that constructs a Dag with an orphan variant declaration, but emit.rs has zero existing #[test] precedent — emit testing happens via integration fixtures. Workers see 'build novel test harness' inside what's billed as an S-scope fix and bounce. Per feedback_construction_over_ratchets: when a brief has friction, fix the brief, don't ratchet the worker. Softened step 4 + acceptance: regression test stays optional. If test setup requires novel scaffolding, route the gap to follow-up. The structural fail-closed at step 2 is the load-bearing change.

Slice step 4 — explicit substrate-signal framing: skipped test means emit-side hermetic-unit-test infrastructure is the missing substrate (feedback_emitter_workaround_is_gap_symptom). 2.

This is a feedback_verify_thesis_claims violation on Director-side brief authoring — claim made without grep verification. Fix: restore step 4 as required, with explicit precedent citation. Worker constructs the failure case via the existing harness (direct Dag, fixture string, or BranchPattern exercise; worker's call on cleanest path).

For Int/Int: OrderedRing.div retype at algebra.dag:182; 3 realizations migrated (rust:816 / go:742 / python:486 + python_target.rs:680 helper). - NOT predicate-entailment (out of scope; M+ + DB-11 reopen). - NOT NonZero-typed-input (deferred to separate per-operand-variance substrate brief; STOP-AND-ESCALATE if chosen). - Per-class sub-lane shape: this PR closes Int/Int only; siblings ([i] indexing, quotient, remainder) queue separately per design doc audit. - feedback_totality_by_omission discipline anchor explicit. Brief now matches feedback_totality_by_omission discipline + design doc recommendation. No substrate prerequisite; dispatchable immediately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): unenumerated-effects — align with design doc Q6 8-req structure Codex BLOCKINGs on nested-optional + unhandled-diagnostic exposed a pattern: I authored R2 worker briefs without fully reading each design doc's Director-actionable recommendation. Pre-emptively re-verified unenumerated-effects against design doc §Q6 to catch the same family of error before reviewers do. Findings: brief was substantively close but missing 3 of 8 design-doc reqs: - Req 3: Resource-threading discipline applied to existing primitives - Req 5: reread(key) primitive in std/ as explicit Slice item (was only mentioned in tests) - Req 7: Asymmetric-tightening worked example in PR body Plus: Slice didn't cite the canonical lens path src/v3/lenses/effect_enumeration.dag from design doc. Plus: STOP-AND-ESCALATE only had 4 generic STOPs; design doc Q6 specifies 4 specific STOPs (path-decision-escalation, pure: Bool carrier, asymmetric-tightening structural gap, Q4.5 P1 NOT a STOP) that I had elided. Reframed Slice as 8 numbered reqs matching design doc verbatim; STOP-AND-ESCALATE rewritten to match design doc Q6 STOPs; Acceptance enumerated per req. This is the third reframe in the unhandled-bugs series — same feedback_verify_thesis_claims violation each time. The pattern suggests Director-side R2 brief authoring should ALWAYS read each design doc's §Director-actionable / §Q-recommendation in full first, not assume. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): nominal-opaque-for-Secret — remove 7th-connective from worker-autonomous options Codex BLOCKING on #836: "New TypeConnective variant — e.g., Opaque(T)" listed as a worker-pick option violates THESIS.md substrate-shape lock. The 6 connectives (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) are canonical (per #811 thesis additions and #827 PM review); a 7th is a C1 stop signal requiring failed-dissolution evidence + Director substrate-design call, not autonomous worker pick. Removed the "new TypeConnective variant" option; replaced with `inhabits`-edge-shape carrier as third option (audit-time check). The explicit STOP-AND-ESCALATE clause now states: 7th connective is the precondition for failed-dissolution-evidence + Director substrate-design call, not a worker path. feedback_verify_thesis_claims still in play — should have grounded substrate-shape options against the THESIS lock before listing Opaque(T) as worker-autonomous. Pattern continues; reading source-of-truth before authoring options is the discipline. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): parametric-algebra-for-Dimensions — close as no-op (substrate already in place) Codex BLOCKING on #836: Declaration.phantom_params and PhantomParameter already exist at dag.rs:186, :217 — explicitly authored for the R2 Dimensions consumer per the doc comment at dag.rs:148-160. phantom_unit_mismatch already wired at infer.rs:1057, :1132. The substrate is fully landed; my brief framing it as 'producer sub-lane to land carrier' is wrong on the same feedback_audit_adjacent_authority_first violation that hit nested-optional / unhandled-diagnostic / unenumerated- effects. Reframed the substrate-side brief as no-op / closed-by-audit: - Documents the audit receipt (5 sites confirming substrate exists) - States the lane is closed - Routes T-Modeling Dimensions consumer to dispatch immediately against the existing carrier - Records the lesson: 'always grep substrate before authoring producer briefs' — discipline doesn't end at brief boundaries. Updated r2-modeling-dimensions-phantom-worker.md correspondingly: - Changed gating from 'do not dispatch until producer signal' to 'NOT GATED — dispatch immediately' - Read-first updated with concrete dag.rs/infer.rs cites - Slice §1 changed from 'confirm producer signal' to 'verify substrate at HEAD' - STOP reframed: existing carrier extension would need Substrate Manager call, not autonomous worker pick Audited siblings: nominal-opaque-for-Secret + cardinality-for-int-lit both verified — no existing substrate (no is_nominal_opaque / MagnitudeBound patterns in dag.rs); both still legitimately producer-side work. Pattern is now four reframes deep on the R2 spin-up wave. The lesson saved is structural: read source-of-truth before authoring options. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-for-int-lit — close as redundant; existing t-substrate-cardinality-int-lit-worker.md is authority Codex BLOCKING on #836: my new R2 spin-up brief duplicates the existing t-substrate-cardinality-int-lit-worker.md, which carries the canonical post-wise-pike-578 re-scope decisions (LiteralBits::Int(i64) stays; String-decimal range facts; i64::MIN deferred to sibling sub-lane). Single-authority violation per INVARIANTS P2. Same feedback_audit_adjacent_authority_first failure as parametric- algebra-for-Dimensions reframe (4 hours ago): assumed substrate authority didn't exist; should have grepped docs/briefs/ before authoring. This is the SECOND R2 spin-up substrate brief closed as redundant — the discipline lesson is structural. Reframed brief as no-op routing doc (documents the audit receipt; routes consumers to the existing authority); updated r2-modeling-int-lit-magnitude-worker.md to cite t-substrate-cardinality-int-lit-worker.md instead. Pattern across the R2 spin-up wave reframes (5 now): 1. nested-optional gating-on-substrate (substrate already past cardinality bridge) 2. unhandled-diagnostic predicate-entailment default (design doc recommends totality-by-omission) 3. unenumerated-effects 8-req design-doc elision 4. parametric-algebra Producer (Declaration.phantom_params already authored explicitly for this consumer) 5. cardinality-for-int-lit Producer (existing brief is authority) All five are 'as…

* docs: PM bundle — R1 Closure Manager + escalation-paths union map Two PM-portion deliverables, bundled per the user-preferred bundling cadence for multiple workstreams. ## R1 Closure Manager (new) — docs/briefs/r1-closure-manager.md Strict-interpretation gate-close authority. Per-HEAD gate audit against ROADMAP.md §"Lane acceptance — .dag gates" surfaced 12+ unwired gates under strict reading ("the release gate IS a .dag program" per THESIS): - T-P0 (3): repeat_string_correct / no_fabrication_sentinel / rest_ops_aligned — features work, no .dag TestClaim wrappers - T-Sub (1): sub_type_alias_where_lowers — PR #703 landed feature, no fixture wrapper - T-TestGen (1 compiles-only): testgen_mock_backed_integration_safe — runner returns NotYetImplemented; M1(2.8) data body blocker - T-PB census (6): hand_rust_at_shim_floor / lens_producer_files_remaining / self_compile_fixed_point / compiler_std_ratchet_zero (T-PB-A) + test_file_generated_from_dag / rust_tests_outside_residual_zero (T-PB-B) — enforced as Rust ratchets, not .dag TestClaims - T-Emit (3): rust_fixtures_rustc_green / generic_bounds_survive / omni_demo_fixtures_green — host-harness only, no .dag wrappers - T-Demo (1): demo_user_authored_lens_rejects_violating_program — no fixture Six mutually-exclusive lanes (R1C-A through R1C-F) at the fixture-file / runner-dispatch-arm level. R1C-A (T-TestGen schema extensions) unblocks R1C-D (T-PB census-as-.dag); other 4 lanes parallel-dispatchable Day-1. Lane variants per user direction: T-PB-A and T-PB-B merged into R1C-D (single predicate-shape work); T-Emit kept (no host-harness pragmatic acceptance). Manager dissolves on R1 all-gates-green declaration; R2 managers spawn post-dissolution per docs/r2-structure.md transition mechanics. No overlap with R2 managers (R2 spawn gated on this manager's close). ## Escalation paths union map (new) — docs/escalation-paths.md Sweep against main HEAD 407a8bc cataloged 45 "if X happens, escalate" clauses across INVARIANTS / ROADMAP / THESIS / r2-structure.md / all docs/briefs / docs/design-*.md / docs/thesis. - 73% GROUNDED (32 clauses): trigger condition is concrete + measurable (specific gate names, file:line citations, mechanical search verifiable) - 27% SOFT (13 clauses): trigger requires human judgment to fire No significant authority conflicts. Three minor naming-tightening opportunities surfaced as Fix 1 / Fix 2 / Fix 3 (applied below). One near-orphan (DB-revision target unattested on main) — resolved by R2 promotion housekeeping; not load-bearing now. Sweep boundary: main only. PR #835 (PM portion) and PR #836 (Director portion) are NOT in this map's current sweep — second-pass sweep planned on those PRs' merge to main. ## Three surgical fixes to source authority docs Each fix is a 1-2 line edit closing an open-resolution-path gap the sweep surfaced: ### Fix 1 — Signal channel naming (docs/r2-structure.md) New paragraph in §"Manager structure" preamble naming the escalation signal channel: GitHub session-inbox issue comment for human-target escalations; cross-manager queue (per R1 "Cross-manager notifications queued" pattern) for inter-manager signals. Worker-brief STOP-AND- ESCALATE clauses no longer need to restate the channel. ### Fix 2 — Director decision-artifact format (docs/r2-structure.md) Extended the "Scope-change escalation" bullet in §"Director" to name where Director's adjudication decision lands: (a) amendment PR to the originating brief OR (b) sibling brief if scope creates new program. Closes the escalation cycle explicitly — originating brief stays open until artifact lands. ### Fix 3 — C1 lane explicit owner (docs/design-substrate-carrier-port-program.md) Two STOP-AND-ESCALATE clauses (Lane E-T :120 and Lane E-P :148) rewritten from "→ C1 lane" to "→ escalate to Director (Director opens a C1 substrate-capability lane if escalation requires substrate work)." Director becomes the explicit receiver; C1 lane becomes the optional dispatch outcome. ## Out of scope for this PR - §6a follow-through brief authoring (next PM deliverable per inbox #828 PM portion; tracked in r2-release-manager.md per PR #835) - B5 / B6 / B7 brief authoring (next PM deliverables per inbox #828 PM portion) - Thesis-claim coverage mapping table (lands at R1 close → R2 promotion transition per r2-structure.md) - Authority matrix structural normalization (per openai-pro PAUSE_AND_REGROUP meta-review on PR #835; deferred — escalation-paths.md provides initial evidence base for any future matrix authoring) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: add R1 Closure Manager ROADMAP registration + §6a follow-through worker brief Two additions to the PM bundle. ## ROADMAP §"R1 Closure Manager" section (new) Small registration section between §"Lane acceptance — .dag gates" and §"Scheduled cleanups". Names the manager + lane structure (R1C-A through R1C-F) + critical-path edge (R1C-A → R1C-D); points at the brief at docs/briefs/r1-closure-manager.md as authority for the per-lane scope. Parallel registration shape to docs/r2-structure.md's §"Manager structure" treatment for R2 managers — short authoritative pointer in ROADMAP, full manager scope in the brief. Manager dissolves on R1 all-gates-green; R2 spawn gated on this dissolution. ## §6a follow-through worker brief (new) Per inbox #828 PM-portion split, this is the next PM deliverable in the queue. Anchored against the existing pick-worker brief at docs/briefs/t-permethodmetadata-pick-worker.md (landed PR #794) so there's no duplicate decision authority — pick is closed; this brief is post-pick scope only. Three consumer-side requirements: 1. Inventory current consumption sites in cost.dag / complexity.dag for the three carrier fields (size_effect / cost_shape / callback_element_position). 2. Bulk-migrate to MethodContract-keyed lookup; retire lens-local reads of *_templates() result fields. 3. Track field-by-field dissolution triggers as named ROADMAP debt rows per §6a:175 (each field has a named upstream-fact landing condition that retires the carrier; when all three trigger conditions fire, MethodContract retires). Slice: inventory → migrate → track. 1-3 PRs at worker discretion. STOP-AND-ESCALATE clauses cite the new escalation channel discipline from docs/escalation-paths.md (channel: GitHub session-inbox; Director decision artifact = amendment PR or sibling brief). Behavioral-regression on R1 gates is non-negotiable STOP; DB-8 drift is STOP; carrier-shape gap discovery is STOP (the pick may need amending). ## What this PR now contains (cumulative) - docs/briefs/r1-closure-manager.md (new) — R1 Closure Manager brief - docs/escalation-paths.md (new) — 45-clause union map - docs/briefs/r2-release-6a-follow-through-worker.md (new) — post-pick worker brief - ROADMAP.md edit — R1 Closure Manager registration section - docs/r2-structure.md edits — signal channel + Director decision-artifact format (Fixes 1+2) - docs/design-substrate-carrier-port-program.md edits — C1 lane explicit owner (Fix 3) ## Out of scope Still-pending PM deliverables per inbox #828: B5 Loop construction-closure audit brief; B6 file-preference rank checklist completion; B7 priority-hint relay (cross-manager signal); thesis-claim coverage mapping table (lands at R1 close → R2 promotion).

Fix: line 3 now reads "Authoritative union receipt + conflict map ... The source briefs remain authoritative on their own escalation clauses (per §How to use below); this doc owns the union view + cross-brief consistency surfacing." Surface change only; the doc's actual authority scope is unchanged from the §"How to use" semantics — clauses live in source briefs; this doc surfaces the union + conflicts. The status line now matches the body.

All three target R2 Release Manager ownership (post-spawn). ## B5 — Loop construction-closure audit (worker brief) S, R2-coupled. Audit-FIRST per parent scope statement (lines 300-314). Step 1: enumerate every Behavior::Loop construction site in lower.rs + anywhere; trace caller path. Step 2 (conditional on audit): - Closure-holds (preferred per feedback_construction_over_ratchets): deliverable is structural integration test asserting closure; speculative LoopKind marker retired. - Closure-fails: marker spec authored as separate brief; escalates to substrate-amendment per synthesis-doc STOP discipline. STOP-AND-ESCALATE clauses cover: (a) ambiguous construction-site origin; (b) marker spec requiring new substrate connective (C1-class escalation per feedback_compiler_is_dag_processor); (c) self-fulfilling closure if audit's own scaffold triggers. ## B6 — file-preference rank checklist completion (worker brief) XS-trivial. Audit-first per feedback_audit_adjacent_authority_first. Two paths: (a) add the three missing modules (computation/induction/ termination) to dag.rs:2735-2764 checklist; (b) document exemption in source if the modules are intentionally exempt. Single-PR deliverable; either +3 line addition or +1 line comment cite. STOP if rank-function semantics are genuinely ambiguous, or if "fix" turns out to require substrate work (don't ratchet on a scaffold already named for dissolution). ## B7 — priority-hint relay to Pure Bootstrap Manager (signal doc, NOT worker brief) Cross-manager signal content snapshot. NOT a worker brief — documents the signal R2 Release Manager queues to R2 Pure Bootstrap Manager once both spawn at R1 close. Payload: lift patch_lower_helpers_generated_type_alias_refinement retirement to PB-Tier1-Sweep priority within R2 Pure Bootstrap Manager's owned-deliverable queue. Pre-spawn: this file documents content. Post-spawn: R2 Release Manager queues the signal as one of its first dispatch actions; R2 PB Manager acks + adjusts priority. Closure trigger: signal delivered + consumed (or dissolution already fired pre-R1); file marks RESOLVED in follow-up cleanup. Distinguished from B5 / B6 worker briefs by the explicit "NOT a worker brief" framing in the synthesis doc; preserves single-authority discipline (deliverables vs signals do not blur). ## Cumulative PR contents (PR #847) - docs/briefs/r1-closure-manager.md - docs/briefs/r2-release-6a-follow-through-worker.md - docs/briefs/r2-release-b5-loop-construction-closure-audit-worker.md (this commit) - docs/briefs/r2-release-b6-file-preference-rank-checklist-worker.md (this commit) - docs/briefs/r2-release-b7-priority-hint-relay-to-pure-bootstrap.md (this commit) - docs/escalation-paths.md - ROADMAP.md (R1 Closure Manager registration section) - docs/r2-structure.md (Fixes 1+2 + earlier signal-channel section) - docs/design-substrate-carrier-port-program.md (Fix 3 — C1 lane explicit owner) ## What's left in PM inbox-#828 queue - Thesis-claim coverage mapping table — gated on R1 close → R2 promotion per docs/r2-structure.md Open call 1; not in this PR.

All four are parallel-dispatchable Day-1 once R1 Closure Manager spawns; sized S or smaller per the manager brief. ## R1C-B — T-P0 fixtures (S; 3 gates) - p0_repeat_string_correct (Day-1, DB-15 schema): authored immediately - p0_no_fabrication_sentinel (ext): audit predicate shape; possibly blocks on R1C-A - p0_rest_ops_aligned (ext): audit predicate shape; possibly blocks on R1C-A Branch on audit per gate; bundle PRs if all DB-15-suffices, split if any blocks on R1C-A schema landing. ## R1C-C — T-Sub sub_type_alias_where_lowers fixture (XS; 1 gate) PR #703 already landed the feature with test_db11_type_alias_where_* integration receipts.

Single PR; dispatchable Day-1. ## R1C-E — T-Emit .dag TestClaim wrappers (S; 3 gates) PB-Runtime ExecuteCommand (PR #792) is the runner enabler. Three gates: - emit_rust_fixtures_rustc_green: ExecuteCommand running rustc on emitted output - emit_generic_bounds_survive: audit-decided shape (ExecuteCommand+grep or structural) - emit_omni_demo_fixtures_green: multi-target; ForAllTargets quantifier may need R1C-A schema, OR can be expressed as 3 ExecuteCommand claims (1 per target) STOP if ForAllTargets needed and not in scope; STOP if PR #792 ExecuteCommand runner doesn't cover the bounded-execution shape. ## R1C-F — T-Demo demo_user_authored_lens_rejects_violating_program (S; 1 gate) Built on T-LensAPI user_authored_lens_compiles (GREEN). Three components: - ~20-line user-authored lens in .dag (e.g., "max external HTTP calls per workflow" per THESIS canonical example) - Violating program (~10-20 lines) - TestClaim with FailsWithDiagnostic predicate (asserts lens rejects violator) Demo artifact also authored per docs/r2-structure.md §"Demo discipline". ## Discipline anchors applied - feedback_construction_over_ratchets — fixtures ground in observable behavior (compiles / output / exit-code), not parallel asserts - feedback_audit_adjacent_authority_first — every brief mandates audit step before authoring (pick predicate / pick lens example / pick path) - All four briefs cite docs/escalation-paths.md as escalation discipline authority ## Out of scope - R1C-A T-TestGen schema extensions worker brief (M; meatier; authored separately) - R1C-D T-PB census-as-.dag worker brief (M-L; meatier; gated on R1C-A; authored separately) - Implementation of any of these briefs (worker dispatch happens at R1 Closure Manager spawn) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: thesis-claim coverage map (R2 promotion Open call 1 deliverable) Per docs/r2-structure.md §"Open calls" item 1 — required pre-promotion audit table mapping every THESIS claim to R1-closed / R2-gated / post-R2-external disposition with gate name + evidence + status. ## Sweep result 74 claims cataloged across THESIS.md §"Thesis claims — complete list" (Tier 1 / Tier 2 / Tier 3 + categorical claims under Concept unifications, Epistemic stacking, Substrate shape, Free consequences, Omni-emission, Meta-process modeling, Self-hosting, Audience duality, Adoption model, Tests-as-data, Enumerable impossible-bug classes, Modeling discipline). ## Coverage statistics - R1-closed: 52 - R2-gated: 18 - post-R2-external: 4 - GAP (no disposition): 0 **Pre-promotion blocker count: 0.** Open call 1's gate is satisfied — every thesis claim has a named disposition + documented evidence. ## Coverage anomalies (partial-status, NOT blockers) Four claims have partial-status notes: 1. Ownership (Tier 1) — full infrastructure may have post-R1 tail 2. Shape A omni-emission — R1 demonstrates 3 of 6+ targets (TS/Swift/HDL post-R1) 3.

Grounding completeness — Tier 1 but R2-gated (intentional, single co-anchor claim per docs/r2-structure.md) ## Doc shape (mirrors escalation-paths.md authority pattern) - Status: PROPOSAL pre-R1-close; promotes to ACTIVE on R1 close → R2 promotion - Authority: descriptive (union receipt + GAP-surfacing); THESIS + ROADMAP + r2-structure.md remain authoritative on claim text + dispositions - Refresh discipline: every release transition; rebuild on new claims ## What this PR (#847) now contains Cumulative deliverables: - docs/briefs/r1-closure-manager.md (R1 Closure Manager brief, 6 lanes) - docs/briefs/r1c-b/c/e/f-*.md (4 trivial R1C lane worker briefs) - docs/briefs/r2-release-6a-follow-through-worker.md - docs/briefs/r2-release-b5-loop-construction-closure-audit-worker.md - docs/briefs/r2-release-b6-file-preference-rank-checklist-worker.md - docs/briefs/r2-release-b7-priority-hint-relay-to-pure-bootstrap.md - docs/escalation-paths.md (45-clause union map) - docs/thesis-claim-coverage.md (74-claim coverage map; this commit) - ROADMAP.md edit — R1 Closure Manager registration section - docs/r2-structure.md edits — Fix 1+2 (signal channel + Director decision artifact) - docs/design-substrate-carrier-port-program.md edits — Fix 3 (C1 lane explicit owner) ## Out of scope - R1C-A (M) and R1C-D (M-L) worker briefs — meatier; defer to next PM iteration - Implementation of any worker brief (R1 Closure Manager dispatches at spawn) - Authority matrix structural normalization per openai-pro PAUSE_AND_REGROUP meta-review — escalation-paths.md + thesis-claim-coverage.md provide evidence base; matrix authoring optional next iteration Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: R2 manager-brief authority matrix (resolves PAUSE_AND_REGROUP meta-review) Per openai-pro PAUSE_AND_REGROUP meta-review on PR #835 sha bfaab66, the recurring "authority ambiguity at stage boundaries" pattern (B7 dual-contract, Grounding pending unbounded, §6a stale framing, B4.1 stale BLOCKING) was being fixed instance-by-instance via wording sweeps. The structural fix is a shared authority matrix that makes the categories disjoint at brief-authoring time. This commit graduates the recurring class out of per-instance review. ## docs/briefs/r2-manager-brief-authority-matrix.md (new) 5 disjoint artifact categories with explicit invariants: 1. Worker brief — dispatchable authoring task; produces concrete deliverable 2. Decision brief — scoped design call (pick + lock); follow-through is distinct Category 1 worker brief (resolves §6a anti-pattern) 3. Cross-manager signal — routes priority/scope info; NOT a worker brief (resolves B7 anti-pattern) 4. Standing reporting duty — continuous-state ledger / monitor; activates on spawn, dissolves on manager dissolution 5. Pre-spawn placeholder — skeleton authored before spawn; graduates into 1-4 OR dissolves at spawn Per-manager deliverable inventory tags every owned deliverable from all 6 R2 managers (Grounding / Substrate / Modeling / Impossible-Bugs / Pure Bootstrap / Release) with category. Inventory references PR #835 (manager briefs), PR #836 (14 Director worker briefs), and PR #847 (this PR's worker briefs + signal doc). Local review checklist (per meta-review recommendation #3): Owned deliverables + Pre-spawn vs post-spawn authority + Autonomous dispatch authority + Sub-briefs sections must agree on owner + artifact type per matrix categorization. Doesn't need new top-level INVARIANTS rule; P2 + P5 already cover; this is the local invariant for the manager-brief family. ## Sweep verification — current state of 6 R2 manager briefs (PR #835 sha 3260d71) All 6 manager briefs verified consistent with matrix: - Grounding: ✅ no category conflicts (Pending bounds fixed in f916fba) - Substrate: ✅ no category conflicts (B4.1 staleness fixed in 74b679b) - Modeling: ✅ no category conflicts - Impossible-Bugs: ✅ no category conflicts (filenames fixed 70df547) - Pure Bootstrap: ✅ no category conflicts - Release: ✅ no category conflicts (B7 dual-contract fixed f916fba; §6a stale framing fixed 74b679b + 3260d71) No additional fix-pushes needed on PR #835 from this matrix introduction. ## docs/r2-structure.md (edit) Added "Manager-brief authority matrix" paragraph in §"Manager structure" preamble, citing the matrix doc as authority. Manager briefs now cite the matrix and stop self-categorizing. ## What this PR (#847) now contains Cumulative deliverables: - docs/briefs/r1-closure-manager.md (R1 Closure Manager brief, 6 lanes) - docs/briefs/r1c-b/c/e/f-*.md (4 trivial R1C lane worker briefs) - docs/briefs/r2-release-6a-follow-through-worker.md - docs/briefs/r2-release-b5-loop-construction-closure-audit-worker.md - docs/briefs/r2-release-b6-file-preference-rank-checklist-worker.md - docs/briefs/r2-release-b7-priority-hint-relay-to-pure-bootstrap.md - docs/briefs/r2-manager-brief-authority-matrix.md (this commit) - docs/escalation-paths.md (45-clause union map) - docs/thesis-claim-coverage.md (74-claim coverage map; 0 GAPs) - ROADMAP.md edit — R1 Closure Manager registration section - docs/r2-structure.md edits — signal channel + Director decision artifact + authority matrix reference (this commit) - docs/design-substrate-carrier-port-program.md edits — Fix 3 (C1 lane explicit owner) ## What's outstanding (out of scope for this PR) - R1C-A and R1C-D worker briefs (M and M-L; meatier; deferred per user's "trivial ones" direction) - Sweep of PR #836's 14 worker briefs against the matrix at PR #836 merge (current sweep is main-only) - Authority matrix becomes ACTIVE on R1 closure → R2 promotion transition per the matrix's status; PROPOSAL until then Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(matrix): add status-consistency + pre-author verification invariants Two additions to the local review checklist on the R2 manager-brief authority matrix, both surfaced by review activity since the matrix's initial landing: ## Status-consistency rule openai-pro APPROVE_WITH_COMMENTS on PR #835 sha 3260d71 found T-Ground-Rust in two contradictory states: deliverables table said DISPATCHED, but Sub-briefs Pending list said "T-Ground-Rust full implementation" pending. Same lane, two authoritative states — the matrix's existing checklist covered owner + artifact type but not status, leaving room for this class. Added rule: a single deliverable cannot be both DISPATCHED/AUTHORED in the deliverables table AND Pending/NOT YET AUTHORED in the Sub-briefs section. Partial-state lanes must scope the partial explicitly in the table (e.g., "PARTIAL — Pilot PR #X done; full implementation pending"). Sub-briefs section is single authority for authored-vs-pending; deliverables table cites that authority without duplicating ambiguously. Fixed in 3ef1509 on PR #835 (T-Ground-Rust row scoped to NOT YET AUTHORED). ## Pre-author verification invariant Director's PR #836 hit feedback_verify_thesis_claims 7 times in one PR authoring cycle (consistently: brief authored without grepping source-of-truth before slicing). The pattern is a separate failure class from categorization — not what the matrix's prior checklist addressed. Added invariant: before authoring a brief that references substrate state, gate condition, existing brief, or design-doc disposition, grep src/v3/std/ + src/v3/spec/ + src/v3/compiler/src/ for state cited; grep docs/briefs/ for existing canonical briefs; read the design doc's §Director-actionable / §Q-recommendation / §Decision in full. Cite specific file:line / brief filename / §ref in Read first. State audit receipt before slicing. This operationalizes feedback_verify_thesis_claims for the brief-authoring family. Doesn't need a new INVARIANTS rule; cited existing P2 + P5 + feedback_verify_thesis_claims as authority. Local invariant collected here as a single review checkpoint. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: R1 Closure Manager — full lane brief queue (R1C-A + R1C-D meatier briefs) Per user direction "lets keep going here until we have full dispatch/briefing for both with thorough review please" — authored the two non-trivial R1 Closure Manager lane worker briefs deferred earlier per "do the trivial ones" direction. R1 Closure Manager lane queue now fully authored. ## R1C-A — T-TestGen schema extensions (M-L; was M before audit) Pre-author audit at main HEAD 407a8bc (per matrix verification invariant) revealed three coupled sub-deliverables, sized M-L total: - **Sub-deliverable A — M1(2.8) list-body lowering for `data` declarations.** Compiler work in lower.rs:2446 (currently rejects `data: List<T> = [...]` as ValueBody::Unparsed). Predecessor for MockBackedInvariant fixture authoring + 6 PB-census predicate authoring. Substrate dependency: T-Substrate ValueBody-list/sum (PR #790; R2 sub-lane) — verify substrate state at brief- dispatch time per feedback_thesis_gate_state_drift. - **Sub-deliverable B — Predicate-shape scoping for 6 PB-census gates.** No `.dag` predicate shape exists for any of the 6 census gates today; ROADMAP line 65 names T-TestGen as scoping authority. R1C-A authors them from scratch. Proposed shapes: CensusBoundCheck / CensusSubsetCount / FixedPointConverges / RatchetZero / GeneratedFromDag (per gate). Audit-first: grep dsl/std/ test_infrastructure.dag for existing predicate-variant pattern; mirror schema discipline. - **Sub-deliverable C — MockBackedInvariant minimal-demo fixture.** Closes testgen_mock_backed_integration_safe gate. Depends on Sub-deliverable A (fixture body uses list literal). 5-10 lines `.dag`. Slice: A → B → C, sequential. STOP-AND-ESCALATE if substrate variant absent, predicate shapes need substrate work, or DB-8 drifts. ## R1C-D — T-PB census-as-`.dag` (M-L) Pre-author audit established census authority at sg0_census_test.rs:166-297 (EXPECTED_HAND_AUTHORED_NON_TEST 41 entries; EXPECTED_HAND_AUTHORED_TEST 77 entries; EXPECTED_HAND_AUTHORED_FRAGMENTS 1 entry). Drift test sg0_v3_hand _authored_census at :387-451 panics with narrative on mismatch. 6 fixtures, one per census gate, each consuming an R1C-A Sub-deliverable B predicate shape: - D.1 pb_hand_rust_at_shim_floor (CensusBoundCheck on NON_TEST list) - D.2 lens_producer_files_remaining (CensusSubsetCount on lens-producer pattern) - D.3 pb_self_compile_fixed_point (FixedPointConverges on bootstrap snapshot) - D.4 pb_compiler_std_ratchet_zero (RatchetZero on consolidation ratchet) - D.5 pb_test_file_generated_from_dag (GeneratedFromDag on test partition) - D.6 pb_rust_tests_outside_residual_zero (CensusBoundCheck on TEST list) Dispatch gated on R1C-A Sub-deliverable B landing. STOP-AND-ESCALATE if predicate shapes don't capture gate semantics (back-pressure to R1C-A); or if cascade-promotion 0-floor work hasn't reduced census to 0 by R1 close declaration time (gates D.1/D.2/D.6 stay RED; Director arbitration). ## R1 Closure Manager status sync Updated r1-closure-manager.md deliverables table + Sub-briefs section to reflect all 6 lane worker briefs as AUTHORED (per matrix's status-consistency rule — table cannot say NOT YET AUTHORED while worker briefs are landed). R1C-A row sized up from M to M-L per audit revealing Sub-deliverable A is compiler work. ## Matrix invariants applied Both new briefs follow the matrix's local checklist: - Categorization: Category 1 (worker brief) — explicit in Cross-refs - Owner / artifact type / status — consistent across deliverables, slice, acceptance, STOP-AND-ESCALATE sections - Pre-author verification — explicit audit receipt section at top of each brief with file:line citations to runner / lowering / schema / census - Discipline anchors named (feedback_construction_over_ratchets, feedback_audit_adjacent_authority_first, feedback_thesis_gate_state_drift, feedback_verify_thesis_claims, feedback_compiler_is_dag_processor, feedback_foundation_over_speed) ## What this PR (#847) now contains (final state expected) - R1 Closure Manager brief + ROADMAP registration + 6 lane worker briefs (R1C-A through R1C-F) — full R1 closure dispatch surface - §6a follow-through worker brief - B5 / B6 / B7 (worker briefs + signal doc) - Escalation-paths union map (45 clauses) - Thesis-claim coverage map (74 claims, 0 GAPs) - Authority matrix (5 categories + per-manager inventory + status-consistency + pre-author verification invariants) - ROADMAP + r2-structure.md + design-substrate-carrier-port-program.md edits R2 spin-up brief queue: complete. R1 closure brief queue: complete. PM inbox #828 fully delivered. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): correct R1C-A citations from self-review pass Self-review pass against the matrix's pre-author verification invariant caught two factual citation misses in r1c-a-t-testgen-schema-extensions-worker.md: ## BLOCKING — wrong file path for TestClaim schema (4 occurrences) Brief cited `dsl/std/test_infrastructure.dag` and `src/v3/std/test_infrastructure.dag` in 4 places (audit receipt at :17 + Sub-deliverable B framing at :61, :66 + Slice PR-B at :87 + Cross-refs Schema authority at :119). That file does NOT exist on main HEAD 407a8bc. The actual TestClaim schema authority lives at: - DSL-side: `dsl/std/verification.dag` (TestClaim at :36; full schema) - v3-mirror: `src/v3/std/verification.dag` (TestClaim.requires at :187) All 4 occurrences corrected to point at the real file. Schema authority line in Cross-refs now also explicitly cites `dsl/std/verification.dag:36` (DSL-side type declaration) for completeness. ## MINOR — predicate dispatch line range was off Brief cited "Predicate dispatch inventory at test_runner.rs:1423-1431 has all 10 predicates wired" — but lines 1423-1431 only contain 9 predicates (Compiles through ExecuteCommand); MockBackedInvariant arm starts at line 1432 and runs through 1448. Corrected to: "in the match block at test_runner.rs:1424-1448 has all 10 predicates wired (Compiles / FailsWithDiagnostic / OutputEquals / PortHasState / CostBounded / LensOutputEquals / DifferentialEquals / AlgebraicLaw / ExecuteCommand wired across :1424-1431; MockBackedInvariant arm at :1432-1448)." ## MINOR — ResourceReference line range corrected Brief cited `src/v3/std/resources.dag:25-27` — actual range is :25-26 (the type spans 2 lines, not 3). Corrected. ## Discipline note Both misses were exactly the failure mode `feedback_verify_thesis_claims` names: state cited from memory rather than grepped at brief-authoring time. The pre-author audit was largely accurate (runner :1432-1448 quote was exact; lower.rs:2446 diagnostic was exact; census line ranges all correct), but two slips made it through. The matrix's pre-author verification invariant worked at the self-review pass level — caught before automated reviewers.

* docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46afe caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): extend cascade across THESIS.md + sibling authorities Resolves claude REQUEST_CHANGES at sha fed6b032 — atomic-cascade self-violation. The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b032 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e6916d.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a1 (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103fad on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103fa on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved.

Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed.

Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79a on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656bbe partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be310b) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be310 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa95e Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close BLOCKING — P2 stale, ExecuteCommand landed via #792 Resolves codex inline BLOCKING at sha 191be310 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:150. Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex non-blocking — capacity-table P2 framing stale Resolves codex non-blocking finding at sha bcac41bb on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:270. Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b1318 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

Eight surface sites dissolve via four substrate carriers (DeclarationRef, structural fold-shape carrier, structural emit-helper carrier, structural extdeps-fixture-set carrier).

Replaced with the canonical 6 (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) per docs/thesis/the-substrate-two-coordinated-shapes.md §'The vocabulary closes here'. Also removed 'typed substrate carriers' from the vocabulary list — substrate carriers are defined using the vocabulary, not part of it. Added a clarifying note that B4's carriers (DeclarationRef, fold-shape, emit-helper, extdeps-fixture-set) are typed declarations composed from the vocabulary, not vocabulary extensions.

Two coordinated fixes: 1. §Read first cites src/v3/std/substrate.dag (live .dag substrate authority) and src/v3/spec/v3_l1.dag:69 (DeclarationRef sentinel meta-type — already exists with consumers in verification.dag, emit_model.dag, python.dag). 2. Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

Likely friction point: brief Slice step 4 asks for a unit test that constructs a Dag with an orphan variant declaration, but emit.rs has zero existing #[test] precedent — emit testing happens via integration fixtures. Workers see 'build novel test harness' inside what's billed as an S-scope fix and bounce. Per feedback_construction_over_ratchets: when a brief has friction, fix the brief, don't ratchet the worker. Softened step 4 + acceptance: regression test stays optional. If test setup requires novel scaffolding, route the gap to follow-up. The structural fail-closed at step 2 is the load-bearing change.

Two coordinated edits: 1. Slice step 4 — explicit substrate-signal framing: skipped test means emit-side hermetic-unit-test infrastructure is the missing substrate (feedback_emitter_workaround_is_gap_symptom). 2. Acceptance — require ROADMAP debt row (new or existing) with named dissolution trigger, referenced in PR body.

This is a feedback_verify_thesis_claims violation on Director-side brief authoring — claim made without grep verification. Fix: restore step 4 as required, with explicit precedent citation. Worker constructs the failure case via the existing harness (direct Dag, fixture string, or BranchPattern exercise; worker's call on cleanest path). STOP-AND-ESCALATE only if construction proves materially harder than precedent suggests, in which case that escalation surfaces a real substrate gap and warrants ROADMAP debt — but the default is 'add the test.'

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): B4.4 — tighten Slice §3 per PM review on #836 PM APPROVE_WITH_COMMENTS on #836: Slice §3's framing of shape (b) (authority + tracked debt parallel-rep) as autonomously acceptable contradicts feedback_construction_over_ratchets + feedback_parallel_representation_debt. Tightened: - Shape (a) is the only autonomous worker path. - Shape (b) requires STOP-AND-ESCALATE to Substrate Manager for a regen-host-loader sub-lane decision; not authorable without explicit Substrate Manager approval citation in the PR body. - Acceptance bullet requires the approval citation when shape (b) lands. - STOP-AND-ESCALATE rephrased to make this explicit; permanent parallel-representation re-escalates even with manager approval. This preserves shape (a) as autonomous; shape (b) becomes a cross-manager design escalation, not a B4.4 implementation call.

Affected briefs (all from R2 spin-up Wave 2 + Wave 3): - r2-substrate-cardinality-for-int-lit-subset.md - r2-substrate-nominal-opaque-for-secret-subset.md - r2-substrate-parametric-algebra-for-dimensions-subset.md (2 refs) - r2-modeling-dimensions-phantom-worker.md - r2-modeling-secret-graduation-worker.md feedback_verify_thesis_claims violation on Director-side brief authoring — assumed path without grep. Same family of error as the earlier emit.rs precedent claim. Mass-replaced via perl; verified no remaining stale refs.

The dissolution is an UNGATED implementation via substrate-constructor invariant. feedback_verify_thesis_claims violation again — should have read the design doc fully before assuming the substrate gate. Rewrote brief to match design doc canonical sketch: - Single predicate (cardinality_idempotent_target) owns the rule - Single allocator (alloc_cardinality_decl) is THE substrate-constructor - API closure on TypeConnective::Cardinality payload (modeling-discipline practice 6) — variant cannot be struct-init'd outside the allocator - 3 hand-Rust + ~22 codegen call sites enumerated per design audit - infer.rs:2902 (concretize_decl_with_subst) explicitly flagged as the killer case for generic-instantiation paths - Surface-syntax T?? decision left to worker (Director-lean: silent normalize) Brief now dispatchable immediately, no producer signal needed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): unhandled-diagnostic — switch to totality-by-omission per design doc §4 recommendation Codex BLOCKING on #836: my R2 worker brief defaulted to predicate-entailment substrate path, but the design doc §4 explicitly recommends totality-by- omission as the Director-actionable path. Predicate-entailment is M+ scope that reopens DB-11's explicitly-closed asymmetric-strip design — design doc explicitly discards it. feedback_verify_thesis_claims violation again — same family as nested- optional reframe. Should have read design doc §4 in full before assuming the path ordering. Rewrote brief to match design doc §4 follow-on shape: - Primary path: per-class totality-by-omission (algebra retype + per- target realization migration). For Int/Int: OrderedRing.div retype at algebra.dag:182; 3 realizations migrated (rust:816 / go:742 / python:486 + python_target.rs:680 helper). - NOT predicate-entailment (out of scope; M+ + DB-11 reopen). - NOT NonZero-typed-input (deferred to separate per-operand-variance substrate brief; STOP-AND-ESCALATE if chosen). - Per-class sub-lane shape: this PR closes Int/Int only; siblings ([i] indexing, quotient, remainder) queue separately per design doc audit. - feedback_totality_by_omission discipline anchor explicit. Brief now matches feedback_totality_by_omission discipline + design doc recommendation. No substrate prerequisite; dispatchable immediately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): unenumerated-effects — align with design doc Q6 8-req structure Codex BLOCKINGs on nested-optional + unhandled-diagnostic exposed a pattern: I authored R2 worker briefs without fully reading each design doc's Director-actionable recommendation. Pre-emptively re-verified unenumerated-effects against design doc §Q6 to catch the same family of error before reviewers do. Findings: brief was substantively close but missing 3 of 8 design-doc reqs: - Req 3: Resource-threading discipline applied to existing primitives - Req 5: reread(key) primitive in std/ as explicit Slice item (was only mentioned in tests) - Req 7: Asymmetric-tightening worked example in PR body Plus: Slice didn't cite the canonical lens path src/v3/lenses/effect_enumeration.dag from design doc. Plus: STOP-AND-ESCALATE only had 4 generic STOPs; design doc Q6 specifies 4 specific STOPs (path-decision-escalation, pure: Bool carrier, asymmetric-tightening structural gap, Q4.5 P1 NOT a STOP) that I had elided. Reframed Slice as 8 numbered reqs matching design doc verbatim; STOP-AND-ESCALATE rewritten to match design doc Q6 STOPs; Acceptance enumerated per req. This is the third reframe in the unhandled-bugs series — same feedback_verify_thesis_claims violation each time. The pattern suggests Director-side R2 brief authoring should ALWAYS read each design doc's §Director-actionable / §Q-recommendation in full first, not assume. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): nominal-opaque-for-Secret — remove 7th-connective from worker-autonomous options Codex BLOCKING on #836: "New TypeConnective variant — e.g., Opaque(T)" listed as a worker-pick option violates THESIS.md substrate-shape lock. The 6 connectives (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) are canonical (per #811 thesis additions and #827 PM review); a 7th is a C1 stop signal requiring failed-dissolution evidence + Director substrate-design call, not autonomous worker pick. Removed the "new TypeConnective variant" option; replaced with `inhabits`-edge-shape carrier as third option (audit-time check). The explicit STOP-AND-ESCALATE clause now states: 7th connective is the precondition for failed-dissolution-evidence + Director substrate-design call, not a worker path. feedback_verify_thesis_claims still in play — should have grounded substrate-shape options against the THESIS lock before listing Opaque(T) as worker-autonomous. Pattern continues; reading source-of-truth before authoring options is the discipline. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): parametric-algebra-for-Dimensions — close as no-op (substrate already in place) Codex BLOCKING on #836: Declaration.phantom_params and PhantomParameter already exist at dag.rs:186, :217 — explicitly authored for the R2 Dimensions consumer per the doc comment at dag.rs:148-160. phantom_unit_mismatch already wired at infer.rs:1057, :1132. The substrate is fully landed; my brief framing it as 'producer sub-lane to land carrier' is wrong on the same feedback_audit_adjacent_authority_first violation that hit nested-optional / unhandled-diagnostic / unenumerated- effects. Reframed the substrate-side brief as no-op / closed-by-audit: - Documents the audit receipt (5 sites confirming substrate exists) - States the lane is closed - Routes T-Modeling Dimensions consumer to dispatch immediately against the existing carrier - Records the lesson: 'always grep substrate before authoring producer briefs' — discipline doesn't end at brief boundaries. Updated r2-modeling-dimensions-phantom-worker.md correspondingly: - Changed gating from 'do not dispatch until producer signal' to 'NOT GATED — dispatch immediately' - Read-first updated with concrete dag.rs/infer.rs cites - Slice §1 changed from 'confirm producer signal' to 'verify substrate at HEAD' - STOP reframed: existing carrier extension would need Substrate Manager call, not autonomous worker pick Audited siblings: nominal-opaque-for-Secret + cardinality-for-int-lit both verified — no existing substrate (no is_nominal_opaque / MagnitudeBound patterns in dag.rs); both still legitimately producer-side work. Pattern is now four reframes deep on the R2 spin-up wave. The lesson saved is structural: read source-of-truth before authoring options. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-for-int-lit — close as redundant; existing t-substrate-cardinality-int-lit-worker.md is authority Codex BLOCKING on #836: my new R2 spin-up brief duplicates the existing t-substrate-cardinality-int-lit-worker.md, which carries the canonical post-wise-pike-578 re-scope decisions (LiteralBits::Int(i64) stays; String-decimal range facts; i64::MIN deferred to sibling sub-lane). Single-authority violation per INVARIANTS P2. Same feedback_audit_adjacent_authority_first failure as parametric- algebra-for-Dimensions reframe (4 hours ago): assumed substrate authority didn't exist; should have grepped docs/briefs/ before authoring. This is the SECOND R2 spin-up substrate brief closed as redundant — the discipline lesson is structural. Reframed brief as no-op routing doc (documents the audit receipt; routes consumers to the existing authority); updated r2-modeling-int-lit-magnitude-worker.md to cite t-substrate-cardinality-int-lit-worker.md instead. Pattern across the R2 spin-up wave reframes (5 now): 1. nested-optional gating-on-substrate (substrate already past cardinality bridge) 2. unhandled-diagnostic predicate-entailment default (design doc recommends totality-by-omission) 3. unenumerated-effects 8-req design-doc elision 4. parametric-algebra Producer (Declaration.phantom_params already authored explicitly for this consumer) 5. cardinality-for-int-lit Producer (existing brief is authority) All five are 'assumed state without grep before authoring'.

Doc comments on the lib + bin now point at the real on-disk path. - Author `tests/integration/r1c_e_emit_gates_dag_test.rs` runner driver: substitutes `env!("CARGO_BIN_EXE_r1c_e_emit_gates")` for the `__R1C_E_BIN__` placeholder at test-crate compile time (manager guidance #973: no checked-in absolute path goes stale, parallel to the `r1_gates.template.dag` build.rs splice discipline). Suite is `#[ignore]` until `rust-green` / `omni-*` subcommands land; the host `#[test]` for `emit_generic_bounds_survive` still runs unconditionally and shares the `r1c_e_gates` body, so the gate is not unwitnessed in CI. Local validation: `cargo check -p v3-compiler --tests` clean (35s). Workspace `cargo test` cannot run in this 11Gi container (v2-compiler codegen OOMs); CI / host validates. Remaining R1C-E acceptance work (next commits): - `rust-green` subcommand: lift `PROGRAM_FIXTURES` + `REFLECTED_FIXTURES` + harness binary infrastructure into the lib so the bin can drive emit→rustc fixture-by-fixture. - `omni-rust` / `omni-python` / `omni-go` subcommands: lift `omni_fixtures` + `rust_stdout` / `go_stdout` / `python_stdout` helpers; one `ExecuteCommand` claim per target (no `ForAllTargets` in the runner today; manager confirmed three-claim decomposition). - Refactor `m1_3_emit_rust_test::emit_rust_fixtures_rustc_green` and `m1_5_emit_omni_demo_test::emit_omni_demo_fixtures_green` to delegate into `r1c_e_gates` so the harness and `.dag` wrapper share one body (#978 review item 1).

…+ reflection completeness + Q6.5 two-layer diagnostic-kind) (#1129) * docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) Director-authored amendment following the 2026-04-24 escalation from PR #693 (sub-child sharp-bear-829 under Surface Manager). Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * resolve merge conflict on ROADMAP.md character-level row — keep phase-1 status edits + char_in_class interpreter-parity sibling row from main * docs(roadmap): name retraction mechanism explicitly in Class 5 Gap 3 audit note (PM review) * docs(roadmap): reconcile Character-level row title with body (per gpt-5.4 review) Row title still said 'consumption gap, not substrate gap' while the body block retracted that claim and cited Class 5 Gap 3 as a substrate dependency for phase-2. Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46afe caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing.

Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e6916d.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a1 (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority.

All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103fad on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103fa on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d169. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189a (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79a on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656bbe partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be310b) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be310 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa95e Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq).

Two coordinated fixes: 1. §Read first cites src/v3/std/substrate.dag (live .dag substrate authority) and src/v3/spec/v3_l1.dag:69 (DeclarationRef sentinel meta-type — already exists with consumers in verification.dag, emit_model.dag, python.dag). 2. Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

Likely friction point: brief Slice step 4 asks for a unit test that constructs a Dag with an orphan variant declaration, but emit.rs has zero existing #[test] precedent — emit testing happens via integration fixtures. Workers see 'build novel test harness' inside what's billed as an S-scope fix and bounce. Per feedback_construction_over_ratchets: when a brief has friction, fix the brief, don't ratchet the worker. Softened step 4 + acceptance: regression test stays optional. If test setup requires novel scaffolding, route the gap to follow-up. The structural fail-closed at step 2 is the load-bearing change.

Two coordinated edits: 1. Slice step 4 — explicit substrate-signal framing: skipped test means emit-side hermetic-unit-test infrastructure is the missing substrate (feedback_emitter_workaround_is_gap_symptom). 2. Acceptance — require ROADMAP debt row (new or existing) with named dissolution trigger, referenced in PR body. Converts the skip from PR-local note (transient) into tracked debt (durable, dispatchable).

The module has #[cfg(test)] mod tests at line 3124 with 12+ tests using compile_to_dag(source, filename) as harness (e.g., go_struct_fields_render_with_separators :3143, shared_walk_to_disj_finds_match_scrutinee_sum_type :3195). This is a feedback_verify_thesis_claims violation on Director-side brief authoring — claim made without grep verification. Fix: restore step 4 as required, with explicit precedent citation. Worker constructs the failure case via the existing harness (direct Dag, fixture string, or BranchPattern exercise; worker's call on cleanest path). STOP-AND-ESCALATE only if construction proves materially harder than precedent suggests, in which case that escalation surfaces a real substrate gap and warrants ROADMAP debt — but the default is 'add the test.'

The dissolution is an UNGATED implementation via substrate-constructor invariant. feedback_verify_thesis_claims violation again — should have read the design doc fully before assuming the substrate gate. Rewrote brief to match design doc canonical sketch: - Single predicate (cardinality_idempotent_target) owns the rule - Single allocator (alloc_cardinality_decl) is THE substrate-constructor - API closure on TypeConnective::Cardinality payload (modeling-discipline practice 6) — variant cannot be struct-init'd outside the allocator - 3 hand-Rust + ~22 codegen call sites enumerated per design audit - infer.rs:2902 (concretize_decl_with_subst) explicitly flagged as the killer case for generic-instantiation paths - Surface-syntax T?? decision left to worker (Director-lean: silent normalize) Brief now dispatchable immediately, no producer signal needed.

Predicate-entailment is M+ scope that reopens DB-11's explicitly-closed asymmetric-strip design — design doc explicitly discards it. feedback_verify_thesis_claims violation again — same family as nested- optional reframe. Should have read design doc §4 in full before assuming the path ordering. Rewrote brief to match design doc §4 follow-on shape: - Primary path: per-class totality-by-omission (algebra retype + per- target realization migration). For Int/Int: OrderedRing.div retype at algebra.dag:182; 3 realizations migrated (rust:816 / go:742 / python:486 + python_target.rs:680 helper). - NOT predicate-entailment (out of scope; M+ + DB-11 reopen). - NOT NonZero-typed-input (deferred to separate per-operand-variance substrate brief; STOP-AND-ESCALATE if chosen). - Per-class sub-lane shape: this PR closes Int/Int only; siblings ([i] indexing, quotient, remainder) queue separately per design doc audit. - feedback_totality_by_omission discipline anchor explicit.

Pre-emptively re-verified unenumerated-effects against design doc §Q6 to catch the same family of error before reviewers do. Findings: brief was substantively close but missing 3 of 8 design-doc reqs: - Req 3: Resource-threading discipline applied to existing primitives - Req 5: reread(key) primitive in std/ as explicit Slice item (was only mentioned in tests) - Req 7: Asymmetric-tightening worked example in PR body Plus: Slice didn't cite the canonical lens path src/v3/lenses/effect_enumeration.dag from design doc. Plus: STOP-AND-ESCALATE only had 4 generic STOPs; design doc Q6 specifies 4 specific STOPs (path-decision-escalation, pure: Bool carrier, asymmetric-tightening structural gap, Q4.5 P1 NOT a STOP) that I had elided. Reframed Slice as 8 numbered reqs matching design doc verbatim; STOP-AND-ESCALATE rewritten to match design doc Q6 STOPs; Acceptance enumerated per req. This is the third reframe in the unhandled-bugs series — same feedback_verify_thesis_claims violation each time. The pattern suggests Director-side R2 brief authoring should ALWAYS read each design doc's §Director-actionable / §Q-recommendation in full first, not assume.

The 6 connectives (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) are canonical (per #811 thesis additions and #827 PM review); a 7th is a C1 stop signal requiring failed-dissolution evidence + Director substrate-design call, not autonomous worker pick. Removed the "new TypeConnective variant" option; replaced with `inhabits`-edge-shape carrier as third option (audit-time check). The explicit STOP-AND-ESCALATE clause now states: 7th connective is the precondition for failed-dissolution-evidence + Director substrate-design call, not a worker path. feedback_verify_thesis_claims still in play — should have grounded substrate-shape options against the THESIS lock before listing Opaque(T) as worker-autonomous.

The substrate is fully landed; my brief framing it as 'producer sub-lane to land carrier' is wrong on the same feedback_audit_adjacent_authority_first violation that hit nested-optional / unhandled-diagnostic / unenumerated- effects. Reframed the substrate-side brief as no-op / closed-by-audit: - Documents the audit receipt (5 sites confirming substrate exists) - States the lane is closed - Routes T-Modeling Dimensions consumer to dispatch immediately against the existing carrier - Records the lesson: 'always grep substrate before authoring producer briefs' — discipline doesn't end at brief boundaries. Updated r2-modeling-dimensions-phantom-worker.md correspondingly: - Changed gating from 'do not dispatch until producer signal' to 'NOT GATED — dispatch immediately' - Read-first updated with concrete dag.rs/infer.rs cites - Slice §1 changed from 'confirm producer signal' to 'verify substrate at HEAD' - STOP reframed: existing carrier extension would need Substrate Manager call, not autonomous worker pick Audited siblings: nominal-opaque-for-Secret + cardinality-for-int-lit both verified — no existing substrate (no is_nominal_opaque / MagnitudeBound patterns in dag.rs); both still legitimately producer-side work. Pattern is now four reframes deep on the R2 spin-up wave. The lesson saved is structural: read source-of-truth before authoring options.

Single-authority violation per INVARIANTS P2. Same feedback_audit_adjacent_authority_first failure as parametric- algebra-for-Dimensions reframe (4 hours ago): assumed substrate authority didn't exist; should have grepped docs/briefs/ before authoring.

Two edits: 1. New "Class 5 Gap 3 — port-carried field values in data bodies" row in the 2026-04-21 post-merge-debt section. The substrate gap was documented in src/v3/DOWNSTREAM_REQUIREMENTS.md:239 but had no ROADMAP ledger row for cross-lane visibility. PR #693's execution surfaced it as the blocker on sub_charclass_in_std_unicode phase-2. 2. Retract the "ready-to-dispatch (no substrate capability gap)" claim on the Character-level row, annotate phase-1 landed via PR #693 (CharClass vocabulary + Rust-mirror structural scanner path), and point phase-2 at the new Class 5 Gap 3 row. Codifies the audit pattern: "this consumption gap has no substrate capability gap" claims must be verified by attempting the retype before the claim lands.

Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46afe caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b032 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e6916d.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a1 (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103fad on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103fa on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d169. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189a (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79a on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656bbe partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be310b) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): align Q6 + capacity-table with Q5.5 path (ii) default Resolves claude APPROVE_WITH_COMMENTS at sha 191be310 on #808. Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa95e Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment.

Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b1318 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

Eight surface sites dissolve via four substrate carriers (DeclarationRef, structural fold-shape carrier, structural emit-helper carrier, structural extdeps-fixture-set carrier).

Replaced with the canonical 6 (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) per docs/thesis/the-substrate-two-coordinated-shapes.md §'The vocabulary closes here'. Also removed 'typed substrate carriers' from the vocabulary list — substrate carriers are defined using the vocabulary, not part of it. Added a clarifying note that B4's carriers (DeclarationRef, fold-shape, emit-helper, extdeps-fixture-set) are typed declarations composed from the vocabulary, not vocabulary extensions.

Two coordinated fixes: 1. §Read first cites src/v3/std/substrate.dag (live .dag substrate authority) and src/v3/spec/v3_l1.dag:69 (DeclarationRef sentinel meta-type — already exists with consumers in verification.dag, emit_model.dag, python.dag). 2. Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

Likely friction point: brief Slice step 4 asks for a unit test that constructs a Dag with an orphan variant declaration, but emit.rs has zero existing #[test] precedent — emit testing happens via integration fixtures. Workers see 'build novel test harness' inside what's billed as an S-scope fix and bounce. Per feedback_construction_over_ratchets: when a brief has friction, fix the brief, don't ratchet the worker. Softened step 4 + acceptance: regression test stays optional. If test setup requires novel scaffolding, route the gap to follow-up. The structural fail-closed at step 2 is the load-bearing change.

Two coordinated edits: 1. Slice step 4 — explicit substrate-signal framing: skipped test means emit-side hermetic-unit-test infrastructure is the missing substrate (feedback_emitter_workaround_is_gap_symptom). 2. Acceptance — require ROADMAP debt row (new or existing) with named dissolution trigger, referenced in PR body.

This is a feedback_verify_thesis_claims violation on Director-side brief authoring — claim made without grep verification. Fix: restore step 4 as required, with explicit precedent citation. Worker constructs the failure case via the existing harness (direct Dag, fixture string, or BranchPattern exercise; worker's call on cleanest path). STOP-AND-ESCALATE only if construction proves materially harder than precedent suggests, in which case that escalation surfaces a real substrate gap and warrants ROADMAP debt — but the default is 'add the test.'

The dissolution is an UNGATED implementation via substrate-constructor invariant. feedback_verify_thesis_claims violation again — should have read the design doc fully before assuming the substrate gate. Rewrote brief to match design doc canonical sketch: - Single predicate (cardinality_idempotent_target) owns the rule - Single allocator (alloc_cardinality_decl) is THE substrate-constructor - API closure on TypeConnective::Cardinality payload (modeling-discipline practice 6) — variant cannot be struct-init'd outside the allocator - 3 hand-Rust + ~22 codegen call sites enumerated per design audit - infer.rs:2902 (concretize_decl_with_subst) explicitly flagged as the killer case for generic-instantiation paths - Surface-syntax T?? decision left to worker (Director-lean: silent normalize) Brief now dispatchable immediately, no producer signal needed.

Predicate-entailment is M+ scope that reopens DB-11's explicitly-closed asymmetric-strip design — design doc explicitly discards it. feedback_verify_thesis_claims violation again — same family as nested- optional reframe.

Pre-emptively re-verified unenumerated-effects against design doc §Q6 to catch the same family of error before reviewers do. Findings: brief was substantively close but missing 3 of 8 design-doc reqs: - Req 3: Resource-threading discipline applied to existing primitives - Req 5: reread(key) primitive in std/ as explicit Slice item (was only mentioned in tests) - Req 7: Asymmetric-tightening worked example in PR body Plus: Slice didn't cite the canonical lens path src/v3/lenses/effect_enumeration.dag from design doc. Plus: STOP-AND-ESCALATE only had 4 generic STOPs; design doc Q6 specifies 4 specific STOPs (path-decision-escalation, pure: Bool carrier, asymmetric-tightening structural gap, Q4.5 P1 NOT a STOP) that I had elided. Reframed Slice as 8 numbered reqs matching design doc verbatim; STOP-AND-ESCALATE rewritten to match design doc Q6 STOPs; Acceptance enumerated per req. This is the third reframe in the unhandled-bugs series — same feedback_verify_thesis_claims violation each time.

The 6 connectives (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) are canonical (per #811 thesis additions and #827 PM review); a 7th is a C1 stop signal requiring failed-dissolution evidence + Director substrate-design call, not autonomous worker pick. Removed the "new TypeConnective variant" option; replaced with `inhabits`-edge-shape carrier as third option (audit-time check). The explicit STOP-AND-ESCALATE clause now states: 7th connective is the precondition for failed-dissolution-evidence + Director substrate-design call, not a worker path. feedback_verify_thesis_claims still in play — should have grounded substrate-shape options against the THESIS lock before listing Opaque(T) as worker-autonomous.

Reframed the substrate-side brief as no-op / closed-by-audit: - Documents the audit receipt (5 sites confirming substrate exists) - States the lane is closed - Routes T-Modeling Dimensions consumer to dispatch immediately against the existing carrier - Records the lesson: 'always grep substrate before authoring producer briefs' — discipline doesn't end at brief boundaries. Updated r2-modeling-dimensions-phantom-worker.md correspondingly: - Changed gating from 'do not dispatch until producer signal' to 'NOT GATED — dispatch immediately' - Read-first updated with concrete dag.rs/infer.rs cites - Slice §1 changed from 'confirm producer signal' to 'verify substrate at HEAD' - STOP reframed: existing carrier extension would need Substrate Manager call, not autonomous worker pick Audited siblings: nominal-opaque-for-Secret + cardinality-for-int-lit both verified — no existing substrate (no is_nominal_opaque / MagnitudeBound patterns in dag.rs); both still legitimately producer-side work.

Title now matches body: mixed classification, consumption for steps 1+3, substrate for step 2. * docs(roadmap): correct Class 5 Gap 3 shape description + soften CharClass phase-2 blocker classification (per gpt-5.4 audit) gpt-5.4's review on 706 @ 71f46afe caught that the row's "remaining gap" description was wrong: field-level shapes (nested records, list literals, declaration refs, Var refs, sum-variant literals) are supported today via FieldValue variants + lower_structural_field_value (dag.rs:328-353, lower.rs:2616+). The actual remaining gap is the top-level ValueBody boundary (non-scalar, non-record top-level bodies). The authority I cited — DOWNSTREAM_REQUIREMENTS.md:239 — is itself stale: it describes the pre-PR-B-unwind shape where FieldValue was LiteralBits-only. PR-B's unwind extended FieldValue to carry Reference / Record / List / Variant, moving the gap to ValueBody. Two fixes: 1. Rewrite the Class 5 Gap 3 row to describe the actual ValueBody boundary, point at code paths (dag.rs, lower.rs) as live authority, flag DOWNSTREAM entry as itself stale, and soften phase-2 CharClass blocker classification to "provisional pending reproduction." 2. Update the Character-level row's phase-2 block to name that the specific shape of the CharClass failure needs concrete reproduction from the escalating sub-child before the blocker is finalized. Recursive audit-pattern instance: the row I wrote to codify "verify live state before claiming substrate gap" itself failed to verify live state. Both incidents (2026-04-23 original row + 2026-04-24 my retraction row) are now cited in the audit-pattern sub-note as examples of the same discipline.

ROADMAP.md gate/baseline prose at :37 / :67 / :68 / :140 — bring lane acceptance bullets and Hand-Rust census paragraph in line with the updated lane summary rows. T-PB-A reads "0 per design-pure-bootstrap-zero (LIVE 2026-04-25)"; T-PB-B notes the TESTING.md residual carve-out is retracted under 0-floor with explicit migration to ExecuteCommand-based .dag TestClaim declarations. 2. docs/design-pure-bootstrap-zero.md promotion section — converted from future-tense ("This doc is PROPOSAL until promoted… promotion is a single Director-authored cascade PR…") to historical past-tense promotion-receipt framing ("This doc was PROPOSAL until promoted; promotion was a single Director-authored cascade PR that did all of the following atomically…"); blocking-clause struck through and resolved inline. Banner cites PR #782 explicitly. 3. docs/r2-structure.md 4th T-Substrate sub-lane scoping — kernel_algebra_ profile excluded (Map<String, AlgebraProfile> body, not list-of-sum; needs distinct ValueBody::Map substrate work, tracked separately as a future sub-lane). Sub-lane re-scoped to 2 consumers (tokenizer charclass phase-2 + Engine sharpened-(b) pilot enumeration), both sharing list-of-sum substrate work. Lane table, dependency DAG, and capacity summary updated for consistency (slot count 9-13, was 10-14). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): extend cascade across THESIS.md + sibling authorities Resolves claude REQUEST_CHANGES at sha fed6b032 — atomic-cascade self-violation. The promotion mechanism in design-pure-bootstrap-zero.md:18-22 explicitly names THESIS.md and "any other authority docs" as required retraction targets; the prior diff updated ROADMAP + r2-structure + design docs but left THESIS.md, compiler-std-consolidation.md, and r1-selfhosting- manager.md pointing at the now-SUPERSEDED ≤5-floor framing. Files: - THESIS.md (5 prose blocks updated): - :164 — facet 3 prose: residual carve-out retracted under 0-floor; tests migrate to ExecuteCommand-based .dag TestClaim declarations. - :248-252 — Self-hosting facet 3: same retraction; everything ports to .dag. - :253-283 — Cost-of-change paragraph + fixed-point acceptance: 0-floor target citing design-pure-bootstrap-zero.md as live authority; hand_maintained_src list shrinks to empty set. - :301-318 — Tests-are-structural-data block: residual carve-out retracted; predicate name pb_rust_tests_outside_residual_zero retained as housekeeping (semantically the residual is empty under cascade). - docs/thesis/compiler-std-consolidation.md (5 references): - Header link to design-pure-bootstrap-zero.md (LIVE) supersedes design-pure-bootstrap.md (SUPERSEDED). - :31 Bootstrap-shim positive-def: 0-floor target; PB-Bootstrap-Process lane named as the dissolution trigger for bootstrap.rs itself. - :87 hand-Rust paragraph: 0 target citing design-pure-bootstrap-zero.md. - :166 Tertiary ratchet: target shifts to 0 on both subsets; live authority re-cited. - :185 Related docs link. - docs/briefs/r1-selfhosting-manager.md (active dispatch brief): - SUPERSEDED-style banner at top: T-PB-A non-test target = 0 (not ≤5); T-PB-B residual carve-out retracted; predicate names retained for housekeeping; cascade-promoted authorities are source of truth. - Slice descriptions for T-PB-A / T-PB-B updated inline. - Framing-question + ask updated to 0-floor / no-residual framing. - Day-1 + up-to-director hand-off bullets updated. - Working-state checklist :111 ≤5 → 0 with cite. - Decisions log :164 ≤5 → 0-floor target updated. - docs/r2-structure.md §2 design call (RETRACTED block): - "Pre-promotion ≤5 irreducible-shim gate-name review" struck through in entirety (both Option A sharpen-and-keep and Option B rename are moot under 0-floor). Section preserved as audit-trail historical context. - Background-doc index: self-hosting anchor updated to design-pure-bootstrap-zero.md as live authority. - docs/design-pure-bootstrap.md SUPERSEDED banner (hardened per non-blocking suggestion): - Banner cites cascade promotion PR #782 explicitly. - New paragraph: "Treat all numeric floors below as retracted" with explicit lines named that quote in isolation (table row, body prose references). Prevents re-quoting from this doc as live authority. Cascade is now atomically consistent across: THESIS.md ↔ ROADMAP.md ↔ TESTING.md ↔ docs/thesis/compiler-std-consolidation.md ↔ docs/briefs/r1-selfhosting-manager.md ↔ docs/r2-structure.md ↔ docs/design-pure-bootstrap-zero.md (LIVE) ↔ docs/design-pure-bootstrap.md (SUPERSEDED). The (Resolved.) self-claim in design-pure-bootstrap-zero.md:29 now holds genuinely. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): correct ExecuteCommand runner-capability claim Resolves codex BLOCKING #1 at sha fed6b032 (P1 live-state violation): TESTING.md:195 and the matching prose in design-pure-bootstrap-zero.md:138 overstated live runner capability — claimed runner support landed in PR #688/#741 with "emit Rust, invoke rustc on output, check exit code" as a structurally-equivalent migration path. Verified against live sources: - src/v3/std/verification.dag:115-119 — ExecuteCommand predicate schema exists (declared via PR #678). - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:292-294 — M1.5 testgen harness allowlists ONLY `command == "true" && args.is_empty() && expect_exit == 0`. - src/v3/compiler/tests/integration/m1_5_testgen_test.rs:394-398 — panics fail-closed on any other shape with explicit "ExecuteCommand shell shape is not supported here (runner-owned — do not treat as ordinary false)". - src/v3/compiler/src/test_runner.rs:352-382 — Rust TestRunner has no match arm for ExecuteCommand; falls through to ClaimResult:: NotYetImplemented. Reality: a TestClaim declaring rustc/python/go invocation is structurally expressible as data today, but executing it is blocked. Full arbitrary-command runner support is the PB-Runtime lane's deliverable. Files updated: - TESTING.md:195 — capability state callout with file:line citations; "Full runner support — arbitrary command + args (rustc/python/go) with exit-code capture — is deferred to the PB-Runtime lane (Zero-Floor program)." Bullet about migration shape preserved as the cascade-named successor pattern, not as a live capability. - TESTING.md:205 — 0-floor-shape gate adds "AND the PB-Runtime lane lands the ExecuteCommand runner extension" as an explicit precondition. - docs/design-pure-bootstrap-zero.md:138 — same correction for the matching prose, with PB-Runtime named as the runner-extension dependency for boundary-test migration. - ROADMAP.md:54 (T-PB-B row) — "predicate schema landed PR #678; runner foundation in #688/#741 with `true`-no-args allowlist only — full arbitrary-command runner support deferred to PB-Runtime lane, blocking the actual boundary-test migration." Dependencies column extended to "DB-15 + T-TestGen + PB-Runtime". The (Resolved.) self-claim at design-pure-bootstrap-zero.md:29 still holds for atomic-cascade-across-authority-docs; this commit closes the remaining capability/claim mismatch flagged by codex. (Codex BLOCKING #2 — THESIS.md + compiler-std-consolidation.md still SUPERSEDED-pointing — was sha-stale; resolved in c85e6916d.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cascade-promotion): remove competing-authority hedge in R1 self-hosting brief Resolves codex BLOCKING at sha 0fb223a1 (P2 single-authority violation). The prior banner contained: > "Operationally R1 closure may still ship before the 0-floor is reached > — the ratchet ensures the trajectory; the gate's acceptance number is > what shifts." This contradicted ROADMAP.md:67 which now reads T-PB-A acceptance = 0. Two competing gate semantics in the cascade is exactly what the atomic-cascade clause forbids. Replaced with single-authority-honest framing: > "R1 closure now requires the 0-floor target by gate semantics: T-PB-A > and T-PB-B are R1 acceptance gates per ROADMAP, and the cascade > promotion changed their acceptance numbers to 0; R1 cannot close > while the SG-0 census carries non-zero hand-Rust." Plus minor sharpening: - "T-PB-A's non-test target is 0" → "non-test acceptance target is 0 per ROADMAP.md:67" (cite the authority). - T-PB-B note adds "blocked on the PB-Runtime runner extension" to keep the capability-state honesty consistent with the recent fix wave. - Predicate-rename housekeeping line moved into banner ("post-cascade housekeeping, not a pre-promotion blocker") — was implicit before. The brief now genuinely inherits the cascade-promoted gate; no competing release authority. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): R2 second-wave worker-escalation fixes Four substantive worker STOP-AND-ESCALATEs from briefs landed in PR #797. All four worker recommendations correct; each needs a Director call + brief update. ## sunny-otter-128 / unenumerated-effects — SPLIT into parser + substrate Worker correctly identified that brief req 2 (declared-effect carrier as part of fn type signature, per feedback_no_annotations) requires net-new parser surface: SurfaceType.Arrow and SurfaceItem.Fn at src/v3/std/parse_surface.dag:71-75 / :185-199 have ZERO effect slots. Without parser surface, every user function would have declared_effects = [] while inference returns non-empty — lens fires EffectLeakageError everywhere on enable. Worker rejected power-through and recommended sibling parser sub-lane (mirror of #797's ValueBody::Map parser split). Director picked split: - NEW: docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md Six reqs covering SurfaceType.Arrow/Fn declared_effects field + surface syntax + lookahead + body parser + lowerer extension + exhaustive-match audit + coproduct dissolution receipt. - MODIFIED: substrate brief banner + req 2 + slice step 1 narrowed to post-parser-extension scope. Pre-flight check NOT a parser-extension step; STOP if parser sub-lane PR not merged. ## sunny-deer-629 / unhandled-diagnostic-paths — REFRAMED to design/scoping Worker found load-bearing evidence at infer.rs:3693-3703: DB-11 deliberately strips refinements at operator dispatch as a designed-in fix for symmetric-operators failure mode. Brief's "attach where b != 0 as a proof for a / b" directly contradicts this design choice. STOP-3 (where-clause conflict with DB-11) is real; STOP-1 (substrate scope) needs net-new substrate (per-operator partiality fact + predicate- entailment check + asymmetric per-operand refinement-honoring) — M+ minimum. ownership_lens precedent in original brief is post-hoc observability, not proof carrier. Worker recommended redirect to design/scoping per nested-optional precedent. Director picked redirect. Brief fully rewritten as design/scoping with four-question structure: (1) DB-11 interaction analysis; (2) substrate proposal for proof-or- totality enforcement; (3) bypass-vs-park decision (a/b/c outcomes with acceptance-theatre risk on user-defined-total-wrapper-only); (4) Director-actionable recommendation. Output is doc PR. ## wise-pike-578 / cardinality-int-lit — RE-SCOPED option (C) Worker verified at HEAD: dsl/std/substrate.dag:31 has LitInt(Int) with Int = Int64; no Int128/UInt128 types; primitives.dag:134-136 closes TargetCarrier at Word64Carrier (no Word128Carrier). Choice (b) i128 implementation requires either path 1 (hierarchy refactor — contradicts non-goal) or path 2 (regen lie between substrate and emit — violates discipline). Worker leaned option (C) re-scope: land reqs 2+3+5 against existing i64; defer req 4 (i64::MIN smoke) to a sibling sub-lane that does proper Int128/Word128 substrate work. Director picked option (C). Brief req 1 re-scoped to drop canonical- carrier-widening; lane value comes from range facts + reconciliation narrowing + out-of-range diagnostic against existing i64. Req 4 explicitly deferred with sibling-sub-lane reference. Sibling sub-lane NOT to be authored or implied in this PR; tracked separately. ## wise-boar-480 / valuebody-map — cross-lane reassignment (no brief change) Worker correctly STOP'd per the brief's own pre-flight check: parser sub-lane has not landed; SurfaceExpr::Map not on main. Director authorized cross-lane reassignment: wise-boar-480 takes the parser sub-lane (t-substrate-valuebody-map-parser-worker.md) since they already have full investigation context. No brief changes needed; the routing decision is in the dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex P2 on Slice/Acceptance lagging req 1 re-scope Resolves codex P2 inline at sha e35103fad on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the prior re-scope (post-wise-pike-578 STOP) updated req 1 to defer carrier-widening but Slice + Acceptance + STOP-AND-ESCALATE still required widening LiteralBits::Int(i64) to an unbounded carrier and passing the i64::MIN smoke. Internally unsatisfiable. Fix: - Slice section retitled "range facts + reconciliation narrowing (against existing i64 carrier)" with explicit note about the re-scope. - Slice step 1 rewritten as "(NOT in scope — deferred)" — explicitly forbids touching LiteralBits::Int shape, dag_scalar_generated.rs regen for that variant, or tokenize i64 parse path. - Slice steps 2-5 reframed: range facts use i64-representable magnitudes; reconciliation narrowing uses existing i64 carrier; diagnostic only for i64-representable out-of-range; smoke tests for req 5 only (req 4 i64::MIN deferred). - Acceptance checklist updated: - Reqs 2, 3, 5 satisfied; reqs 1 + 4 explicitly noted as re-scoped/deferred. - LiteralBits::Int(i64) carrier untouched (no widening; no parallel; no shape change). - i64::MIN smoke marked DEFERRED with sibling-sub-lane reference. - STOP-AND-ESCALATE bullet 1 rewritten: "Pressure to widen the carrier" — explicit STOP if execution surfaces range-fact narrowing requiring carrier-widening; that's the boundary the re-scope drew; belongs in sibling Int128/Word128 sub-lane. Brief now consistently treats carrier-widening as out-of-scope across all sections. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): T-Substrate cardinality-int-lit — close codex BLOCKING #1 on range-fact carrier honesty Resolves codex BLOCKING #1 at sha e35103fa on docs/briefs/t-substrate-cardinality-int-lit-worker.md:31. Real: the post-wise-pike-578 re-scope kept LiteralBits::Int(i64) carrier but req 2 required range facts using "the SAME magnitude carrier as req 1" — meaning i64-typed range bounds. u64's max (2^64-1) doesn't fit in i64; range fact for u64 would have to truncate, omit, or mirror in Rust (representation drift). All three options violate fail-closed declared-facts discipline (P1 / P3). Fix: - Req 2 rewritten to specify String-decimal representation: range_min_inclusive: String + range_max_inclusive: String fields on IntegerPrimitive carrying decimal magnitude (e.g., "-128"/"127" for i8; "0"/"18446744073709551615" for u64). - Explicit reasoning why String-decimal: u64's max doesn't fit in i64; binding range bounds to literal carrier forces truncation/ omission/mirror-drift; all violate fail-closed declared-facts discipline. - Bridge framing: String-decimal is pending the sibling Int128/ Word128 sub-lane; both range bounds and literal payload migrate to typed carrier when that lands. - Req 3 updated for String-decimal comparison semantics: reconciliation parses both bounds and literal magnitude into a common comparison space (i128 host comparison primitive — host narrowing, NOT carrier widening). Bounded by what the i64-typed literal can express; any i64-representable literal compares against any width's String-decimal bound. Carrier discipline preserved. Codex BLOCKING #2 (Slice/Acceptance contradicting req 4 deferral) is sha-stale — already resolved at 3e142d169. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-int-lit — close codex BLOCKING on Slice/Acceptance still i64-typed Resolves codex BLOCKING at sha 0815189a (post-#799-merge feedback). Real residual: req 2 specifies String-decimal range bounds (to cover u64::MAX which doesn't fit in i64) but lines 31, 44, and acceptance bullet still referenced "i64-bounded magnitudes" / "Int64 carrier" / "i64-representable magnitudes" for the range facts. Two incompatible authorities for the same range-fact shape — would let a worker satisfy the slice while truncating/omitting u64 bounds (P3 fail-closed violation). Fix: - Line 31 (req 1 re-scope clarification): updated to explicitly state "range facts (req 2) use String-decimal representation (width- independent; covers u64::MAX which doesn't fit in i64)". Distinguished literal *payload* (stays i64) from range-bound *representation* (String) — both serve req 1's "no carrier widening" boundary. - Line 44 (slice step 2): updated from "Range bounds use i64- representable magnitudes" to "Range bounds use String-decimal representation per req 2" with concrete example (u64 bounds). - Acceptance bullet: updated from "Range facts on integer algebras (substrate-declared, not Rust-mirrored)" to add "using String-decimal representation ... width-independent; u64 bounds expressible without truncation." The brief now consistently treats range bounds as String-decimal across req 2, req 3, slice, acceptance, and the req 1 clarification — no remaining authorities saying i64-typed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): redirect unenumerated-effects chain to closed-system framing User + PM exchange 2026-04-25 surfaced that the in-flight effects chain was importing wrong assumptions from external languages (declared-effects-as-annotation + lens-vs-declaration check). Right framing under gunbc's closed-system discipline is parallel to complexity: every effect derives structurally from the composition of typed primitive operations; nothing can hide because there's no escape hatch; nothing needs annotation because the structure IS the registry. Four doc-only actions: 1. NEW docs/briefs/t-impossiblebugs-unenumerated-effects-design.md. Frames the closed-system answer with PM's 5-behavior synergy table (Value/Transform/Branch/Loop/Bind as universal compositional-fold pattern). Four worked examples; aggressive reading on redundancy (compile-error-by-construction via referential-transparency proof; reread() primitive for legitimate cases); implementation-brief shape in §Q6. 2. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-worker.md. 3. SUPERSEDED banner on docs/briefs/t-impossiblebugs-unenumerated-effects-parser-worker.md. Notes Fn→Arrow refactor brief stays dispatchable as independent value. 4. THESIS:345-347 bug-class amendment: Tier 1 impossible-by- construction framing replaces lens-detection framing. Memory file feedback_closed_system_effects.md saved separately; cross-link added to feedback_construction_over_ratchets.md. Net cost: doc-level cleanup. Zero substrate code rework. Foundation (OperationEffect + service-call infrastructure + 5-behavior substrate) already exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): Q5.5 — operation type-signature shape IS the effect Per PM convergence review on #808 + user's deeper 2026-04-25 framing: the closed-system framing landed in #808 retired the user-facing annotation but kept OperationEffect taxonomy as substrate-level tagging. User's deeper framing: the taxonomy ITSELF is parallel-representation — operations are intrinsically read-shaped or write-shaped via their TYPE-SIGNATURE SHAPE (returned-modified-resource → write; returns- derived-value-only → read). Tagging operations with Read | Upsert | Create | Append | Delete names what the structure already says. Three changes: 1. Design doc Q5.5 added — "OperationEffect taxonomy: retain as normalized view, or retire as parallel-representation?" - Two paths: (i) tags derived from signature shape (acceptable normalized view) vs (ii) tags declared per-primitive (parallel- representation; retire). - Audit-as-existence-check (Q4 req 2 reframed): all effectful primitives derive cleanly from signature shape → path (i); any primitive needs hand-declared tag → path (ii) by existence proof. - Director default: path (ii). Logging primitives that return Unit are likely the audit's existence-proof. - Two design-question resolutions: (a) external effects not in return type → resource-threading discipline (typed param returned modified, IO-monad-without-the-monad pattern); (b) transactional grouping → derived structural fact from Bind composition + typed transaction primitives. 2. Q4 reqs revised: req 2 from "tag every primitive with explicit OperationEffect signature" to "audit-as-existence-check that every primitive's type signature derives the right effect classification"; req 3 added (resource-threading discipline); req 6 added (transactional-pattern lens). Req 1 (effects lens) anchors on operation type-signature shape, not on hand-declared tags. 3. THESIS:345-347 amendment strengthened — "operations are intrinsically read-shaped or write-shaped via their type-signature shape; consumers walk the signatures directly; there is no parallel taxonomy or annotation layer to declare or maintain. Tracking effects as a separate enumerated concept IS the bug pattern, dissolved by construction." Plus references to resource-threading discipline + transactional grouping as derived structural fact. Memory file feedback_closed_system_effects.md updated to reflect the deeper framing (type-signature-shape, not taxonomy-tagging) + resource-threading discipline section + transactional-patterns section. Net cost: doc-only delta on top of #808. Substrate retirement (OperationEffect enum + derive_op_effect + idempotency.dag re-anchor) deferred to the audit-as-existence-check phase of the implementation brief; surfaced as Q5.5 OPEN CALL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close codex BLOCKING — honest live-state on signature-shape coverage Resolves codex BLOCKING at sha d49ce79a on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:116. Real: the prior text claimed service primitives "already carry typed effect signatures" presenting future audit-state as current substrate fact (P1 violation). My Q5.5 amendment at 2dc656bbe partially fixed the OperationEffect line but left a parallel over-claim on the new "signature-shape coverage" framing. Fix: Q4 substrate-state listing rewritten to honestly distinguish: - Live: Behavior enum + substrate foundation (the principle that operations should carry signature shape). - Incomplete: signature-shape coverage across actual primitives. HTTP-derived primitives carry implicit shape via derive_op_effect's method-table; logging/mutation primitives that return Unit or don't thread their target resource do NOT carry the structural shape that would express read-vs-write. Achieving full coverage is required work under reqs 2 + 3, not a current fact. - Pending audit-as-existence-check: OperationEffect + derive_op_effect (path (i) vs (ii) per Q5.5). Honest live-state callout added explicitly: "the closed-system FOUNDATION (5 behaviors + DAG substrate + the principle that operations should carry signature-shape) is live. The IMPLEMENTATION COVERAGE across all effectful primitives is partial. Req 2 + req 3 are the work that closes the gap." Brief now distinguishes principle-is-live (foundation) from coverage-is-partial (audit work) without conflating them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(closed-system-effects): Q4.5 — load-bearing pre-conditions for closed-system claim Per PM follow-up review on #808 + user's stronger discipline framing ("substrate must make bypass structurally impossible at every layer of the transport stack"): the closed-system claim is honest only when typed primitives ARE the path. Today two structural holes exist where bypasses sidestep the typed-primitive substrate. Both surfaced explicitly as Q4.5 pre-conditions — load-bearing for the lens's coverage claim. Three changes: 1. NEW Q4.5 section "Pre-conditions (load-bearing for the closed- system claim)" inserted between Q4 and Q5: P1 — Extdeps typed-primitive consumption structurally enforced. Substrate must make `messages: Json` impossible to declare in service definitions; typed `LlmMessage` / `ContentBlock` / `GitHubAuthToken`-with-full-scopes are the only path. Tracked debt at ROADMAP.md:153-154 (LLM provider flattening) + `dsl/extdeps/github/auth.dag:13-24` (scopes/expires_at discarded). Required prereq for full lens coverage; lens can land first + surface structural-coverage-gap diagnostics on bypass surfaces so the gap becomes visible rather than silent. P2 — `ExecuteCommand` fully materialized as typed runner primitive. TESTING.md (post-#782) committed to 0-residual but ExecuteCommand isn't fully materialized; deleting Rust boundary tests creates verification gap. Already named under PB-Runtime in Zero-Floor; signal pending. Pre-requisite for ANY Rust boundary-test deletion. 2. Old leftover duplicate Q5 section deleted (artifact from prior Q5/Q5.5 reshape; second copy of asymmetric-tightening text was in the file alongside the earlier Q5 instance). 3. Worker-discretion-vs-Director-call section in Q4.5: lens implementation worker dispatchable now (reports gaps as findings); P1 closure is substantive substrate work touching extdeps (dedicated lane); P2 closure is PB-Runtime (signal pending). Net: design doc now honestly distinguishes principle-is-live (Q4 rewrite at 191be310b) from coverage-is-partial (Q4.5 prereqs named explicitly). The closed-system claim has explicit pre- conditions documented; implementation brief discovers them as known dependencies, not as STOP-AND-ESCALATEs.

Two real residuals after the Q5.5 reframe: 1. Q6's reqs/STOPs/acceptance still framed under path (i) — said "audit + tag std/ primitives — every effectful primitive carries an explicit OperationEffect signature." Directly contradicted Q4 (post-191be310b) + Q5.5's path (ii) default + the THESIS amendment ("there is no parallel taxonomy to declare or maintain"). Worker reading Q6 in isolation would author the retracted shape. 2. Capacity / sequencing table line about "audit lane (tag std/ primitives with effect signatures)" carried the same stale framing. 3. Q6 STOP "primitive performing side effects without an OperationEffect tag" assumed tag-as-authority; under path (ii) the STOP shape is "primitive whose signature doesn't structurally reveal its effect." Plus the duplicate Q5 section claude flagged at :184-191 is sha-stale (already fixed at f073aa95e Q4.5 commit). ## Q6 fixes - Reqs renumbered + reframed: - Req 1 anchors on operation type-signature shape (not hand-declared OperationEffect tags); composition reads from signature shape per Q2 table. - Req 2 changed from "audit + tag every primitive" to "audit-as-existence-check" — verify signature-shape coverage; ANY primitive needing a hand-declared tag IS the existence-proof for path (ii) retirement. - Req 3 added: resource-threading discipline applied to existing primitives (logging that returns Unit gets reshaped per audit). - Req 6 added: transactional-pattern lens (Bind composition + Transaction → Transaction'). - Req 7 added: asymmetric-tightening worked example in PR body (per claude review observation; the one place declaration-shaped surface re-enters). - Req 8 (was 5): tests now reference signature-shape derivation explicitly, not tag lookup. - STOPs reframed: - "OperationEffect retirement decision" — audit produces path (i) vs (ii) verdict; substrate retirement is its own dedicated sub-lane; this lane does NOT absorb it. - Pure/impure carrier STOP notes that "pure" should also derive from signature shape (pure functions don't return modified resources) — so the STOP itself may dissolve under further design. - Q4.5 P1 explicitly NOT a STOP — lens reporting structural- coverage-gap on extdeps bypass surfaces is the lens delivering its foundation-gap-visibility value. - Q4.5 P2 explicitly independent — lens doesn't depend on ExecuteCommand materialization. - Acceptance extended: lens reports gap diagnostics on P1 bypass surfaces; audit produces existence-proof verdict for Director re-decision; asymmetric-tightening worked example in PR body. ## Capacity / sequencing table Replaced "1 audit lane (tag std/ primitives with effect signatures)" with "1 audit-as-existence-check lane (verify primitives' signature- shape coverage; NOT 'tag every primitive') — produces the path (i) vs (ii) verdict on OperationEffect retention." Added Q4.5 P1+P2 prereq lanes to the net summary. Closing line: "The taxonomy- retirement scope (substrate-side) is not in this lane — it's surfaced by audit and routed to dedicated retirement lane if path (ii) wins." Net: design doc internally consistent across Q1-Q6 + Q4.5 + capacity table. Worker reading Q6 in isolation now sees path-(ii)-default framing matching Q4 + Q5.5 + THESIS amendment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(closed-system-effects): close BLOCKING — P2 stale, ExecuteCommand landed via #792 Resolves codex inline BLOCKING at sha 191be310 on docs/briefs/t-impossiblebugs-unenumerated-effects-design.md:150. Real: my Q4.5 P2 framing described ExecuteCommand as still NotYetImplemented (M1.5 allowlist + Rust TestRunner returning NotYetImplemented), but PR #792 landed the PB-Runtime ExecuteCommand extension before this PR's authoring. TESTING.md:195 capability-state callout confirms: - Rust TestRunner + M1.5 testgen harness share one std::process path for arbitrary command + args + expect_exit_code. - M1.5 allowlist + fail-closed panic retired. - Distinguishable ClaimResult::Fail messages for spawn / timeout / policy / exit-mismatch. - Linux unshare(1) namespace isolation on host-allowing systems. - T-PB-B-1 boundary migration example landed. Fix: P2 section rewritten: - Header retitled "ExecuteCommand runner primitive: LANDED (PR #792); residual is bulk-migration." - Status update naming PR #792 + the post-#792 capability state (allowlist retired, etc.). - Honest acknowledgement: "My earlier P2 framing was stale." - Residual narrowed to bulk-migration of existing Rust Command::new boundary tests (tracked as ROADMAP residual, not lens prereq). - Sequencing reframed: P2 was always orthogonal to the effects lens itself; bulk migration proceeds at its own pace; lens not blocked. Q4.5 footer updated: - "P1 + P2 closure" → "P1 closure (P2 runner-primitive landed via #792; only consumer-side bulk migration remains)" - Worker-discretion-vs-Director-call P2 line updated: "runner primitive landed; only consumer-side bulk migration remains; tracked as ROADMAP residual, independent of the lens." Q6 STOP for P2 updated: - "the lens itself doesn't depend on P2; only TESTING.md's 0-residual claim does" → "runner primitive landed via PR #792 (post-Q4.5- authoring update). The lens itself never depended on P2; bulk consumer migration is residual ROADMAP work and remains independent of this lane." Brief now reflects live state. The closed-system claim's prereq landscape is honest: - P1 (extdeps typed-primitive consumption): real prereq, tracked debt at ROADMAP:153-154. - P2 (ExecuteCommand runner): satisfied via #792; bulk migration is consumer-side residual, not foundation work.

Real residual: capacity-table line still listed P2 as "`ExecuteCommand` materialization" prereq + framed both P1 and P2 as "pre-existing tracked-debt" — but my prior 57a9b1318 fix established that PR #792 already landed the runner primitive, so P2 is no longer a materialization prereq. Fix: capacity-table P2 line rewritten to distinguish P1 (real prereq) from P2 (residual, not prereq): - P1: extdeps typed-primitive consumption — pre-existing tracked debt at ROADMAP:153-154; load-bearing for the lens's full-coverage claim. - P2: ExecuteCommand runner primitive landed via PR #792; only consumer-side bulk migration of existing Rust Command::new boundary tests remains (tracked as ROADMAP residual, independent of the lens; not a materialization prereq). Brief now consistently treats P2 as bulk-migration-residual across: - §Q4.5 P2 section header (LANDED via PR #792; residual is bulk-migration). - §Q4.5 footer (P2: runner primitive landed; only consumer-side bulk migration remains). - Q6 STOP for P2 (runner primitive landed; bulk migration is residual ROADMAP work). - §Capacity / sequencing impact (P2 as residual, not prereq).

Also removed 'typed substrate carriers' from the vocabulary list — substrate carriers are defined using the vocabulary, not part of it. Added a clarifying note that B4's carriers (DeclarationRef, fold-shape, emit-helper, extdeps-fixture-set) are typed declarations composed from the vocabulary, not vocabulary extensions.

Two coordinated fixes: 1. §Read first cites src/v3/std/substrate.dag (live .dag substrate authority) and src/v3/spec/v3_l1.dag:69 (DeclarationRef sentinel meta-type — already exists with consumers in verification.dag, emit_model.dag, python.dag). 2. Phase 1 #1 reframed: 'land DeclarationRef' → 'consume the existing DeclarationRef'. The work is consumer migration + any role-extension layer the audit reveals, NOT designing or landing the carrier. Phase 1 #2-#4 (fold-shape, emit-helper, extdeps-fixture-set carriers) keep their 'new' framing but explicitly require sub-briefs to grep src/v3/std/ + src/v3/spec/ for existing authority before authoring 'design and land' framing — per feedback_verify_thesis_claims + feedback_emitter_workaround_is_gap_symptom.

Likely friction point: brief Slice step 4 asks for a unit test that constructs a Dag with an orphan variant declaration, but emit.rs has zero existing #[test] precedent — emit testing happens via integration fixtures. Workers see 'build novel test harness' inside what's billed as an S-scope fix and bounce. Per feedback_construction_over_ratchets: when a brief has friction, fix the brief, don't ratchet the worker. Softened step 4 + acceptance: regression test stays optional. If test setup requires novel scaffolding, route the gap to follow-up. The structural fail-closed at step 2 is the load-bearing change.

Two coordinated edits: 1. Slice step 4 — explicit substrate-signal framing: skipped test means emit-side hermetic-unit-test infrastructure is the missing substrate (feedback_emitter_workaround_is_gap_symptom). 2. Acceptance — require ROADMAP debt row (new or existing) with named dissolution trigger, referenced in PR body.

This is a feedback_verify_thesis_claims violation on Director-side brief authoring — claim made without grep verification. Fix: restore step 4 as required, with explicit precedent citation. Worker constructs the failure case via the existing harness (direct Dag, fixture string, or BranchPattern exercise; worker's call on cleanest path).

Predicate-entailment is M+ scope that reopens DB-11's explicitly-closed asymmetric-strip design — design doc explicitly discards it. feedback_verify_thesis_claims violation again — same family as nested- optional reframe.

Pre-emptively re-verified unenumerated-effects against design doc §Q6 to catch the same family of error before reviewers do. Findings: brief was substantively close but missing 3 of 8 design-doc reqs: - Req 3: Resource-threading discipline applied to existing primitives - Req 5: reread(key) primitive in std/ as explicit Slice item (was only mentioned in tests) - Req 7: Asymmetric-tightening worked example in PR body Plus: Slice didn't cite the canonical lens path src/v3/lenses/effect_enumeration.dag from design doc. Plus: STOP-AND-ESCALATE only had 4 generic STOPs; design doc Q6 specifies 4 specific STOPs (path-decision-escalation, pure: Bool carrier, asymmetric-tightening structural gap, Q4.5 P1 NOT a STOP) that I had elided. Reframed Slice as 8 numbered reqs matching design doc verbatim; STOP-AND-ESCALATE rewritten to match design doc Q6 STOPs; Acceptance enumerated per req. This is the third reframe in the unhandled-bugs series — same feedback_verify_thesis_claims violation each time.

The 6 connectives (Atom | Conj | Disj | Arrow | Cardinality | Instantiation) are canonical (per #811 thesis additions and #827 PM review); a 7th is a C1 stop signal requiring failed-dissolution evidence + Director substrate-design call, not autonomous worker pick. Removed the "new TypeConnective variant" option; replaced with `inhabits`-edge-shape carrier as third option (audit-time check). The explicit STOP-AND-ESCALATE clause now states: 7th connective is the precondition for failed-dissolution-evidence + Director substrate-design call, not a worker path. feedback_verify_thesis_claims still in play — should have grounded substrate-shape options against the THESIS lock before listing Opaque(T) as worker-autonomous. Pattern continues; reading source-of-truth before authoring options is the discipline. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): parametric-algebra-for-Dimensions — close as no-op (substrate already in place) Codex BLOCKING on #836: Declaration.phantom_params and PhantomParameter already exist at dag.rs:186, :217 — explicitly authored for the R2 Dimensions consumer per the doc comment at dag.rs:148-160. phantom_unit_mismatch already wired at infer.rs:1057, :1132. The substrate is fully landed; my brief framing it as 'producer sub-lane to land carrier' is wrong on the same feedback_audit_adjacent_authority_first violation that hit nested-optional / unhandled-diagnostic / unenumerated- effects. Reframed the substrate-side brief as no-op / closed-by-audit: - Documents the audit receipt (5 sites confirming substrate exists) - States the lane is closed - Routes T-Modeling Dimensions consumer to dispatch immediately against the existing carrier - Records the lesson: 'always grep substrate before authoring producer briefs' — discipline doesn't end at brief boundaries. Updated r2-modeling-dimensions-phantom-worker.md correspondingly: - Changed gating from 'do not dispatch until producer signal' to 'NOT GATED — dispatch immediately' - Read-first updated with concrete dag.rs/infer.rs cites - Slice §1 changed from 'confirm producer signal' to 'verify substrate at HEAD' - STOP reframed: existing carrier extension would need Substrate Manager call, not autonomous worker pick Audited siblings: nominal-opaque-for-Secret + cardinality-for-int-lit both verified — no existing substrate (no is_nominal_opaque / MagnitudeBound patterns in dag.rs); both still legitimately producer-side work. Pattern is now four reframes deep on the R2 spin-up wave. The lesson saved is structural: read source-of-truth before authoring options. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): cardinality-for-int-lit — close as redundant; existing t-substrate-cardinality-int-lit-worker.md is authority Codex BLOCKING on #836: my new R2 spin-up brief duplicates the existing t-substrate-cardinality-int-lit-worker.md, which carries the canonical post-wise-pike-578 re-scope decisions (LiteralBits::Int(i64) stays; String-decimal range facts; i64::MIN deferred to sibling sub-lane). Single-authority violation per INVARIANTS P2. Same feedback_audit_adjacent_authority_first failure as parametric- algebra-for-Dimensions reframe (4 hours ago): assumed substrate authority didn't exist; should have grepped docs/briefs/ before authoring. This is the SECOND R2 spin-up substrate brief closed as redundant — the discipline lesson is structural. Reframed brief as no-op routing doc (documents the audit receipt; routes consumers to the existing authority); updated r2-modeling-int-lit-magnitude-worker.md to cite t-substrate-cardinality-int-lit-worker.md instead. Pattern across the R2 spin-up wave reframes (5 now): 1. nested-optional gating-on-substrate (substrate already past cardinality bridge) 2. unhandled-diagnostic predicate-entailment default (design doc recommends totality-by-omission) 3. unenumerated-effects 8-req design-doc elision 4. parametric-algebra Producer (Declaration.phantom_params already authored explicitly for this consumer) 5. cardinality-for-int-lit Producer (existing brief is autho…
