From cf164c72f0cdb3fbb29c15a286bde1eb9a3216e4 Mon Sep 17 00:00:00 2001 From: Brian Searls Date: Fri, 24 Apr 2026 00:42:05 -0400 Subject: [PATCH 01/77] docs(roadmap): record CharClass phase-1 closure + add Class 5 Gap 3 ledger row (post-#693 escalation) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

Current `OperatorKind::Logical(_)` dispatch in the three emitters is hardcoded (`if let OperatorKind::Logical(_)` branches bypass the algebra-field resolution that arithmetic operators use). The substrate already models `BooleanAlgebra` with `meet/join/complement` per `dsl/std/algebra.dag:230-236`, and comments there state *"Bool inhabits BooleanAlgebra"* — but the `inhabits` edge isn't structurally landed.

Owner: 1e-2b lane (Path A). +- **Class 5 Gap 3 — port-carried field values in `data` bodies (substrate capability gap)**: authoritative enumeration at `src/v3/DOWNSTREAM_REQUIREMENTS.md:239` (gap partially closed at M1(2.8) for literal-only fields via `ValueBody::Structural` / `SurfaceExpr::Record` / `lower_record_to_structural`; remaining open half is port-carried field values — nested records, list literals, declaration references, `Var` references, sum-variant literals). `compile_to_dag` rejects these shapes inside `data` bodies today. **Consumer impact surfaced 2026-04-24** by PR #693 escalation (sub-child `sharp-bear-829` under Surface Manager): blocks `sub_charclass_in_std_unicode` phase-2 — specifically the `tokenize.dag` retype of `StringEscapeSpec.suffix`, `LocalPunctSpec.pattern`, `OperatorSpec.symbol`, `dag_keyword_set` keys, etc. to `Char` / `List` + `CharClass` sum-variant literals. Adjacent future retype-to-structured-carrier lanes (syntax.dag keyword sets, other opaque-string fields) will hit the same wall. Dissolution: extend `compile_to_dag` to parse port-carried field values in data bodies. Alternative design call (out of scope here): shift the authority shape for these configs from `data` bodies to extractor-over-unparsed-source. Owner: unassigned; substrate-capability scope — routes through a self-hosting / substrate-capability lane, not through the consuming lanes. **Audit pattern:** future "this consumption gap has no substrate capability gap" claims should be verified by attempting the retype before the claim lands — the 2026-04-23 authoring of the Character-level row (this file, `:354`) made this claim and was factually wrong; retracted 2026-04-24. - **`emit_rust_module` gap: SurfaceLiteral → LiteralBits rename**: substrate declares `LitInt/LitBool/LitString` in `LiteralBits`; Rust enum is `Int/Bool/String`; no rename facility in `emit_rust_module` causes connective-producing slices (per #612's staging choice notes) to fail on this. Dissolution: add per-variant name mapping in spec or rename-facility in emit. Owner: unassigned; blocks deeper SG-3g slices. - **`emit_rust_module` gap: `render_variant_constructor` fails on external tuple variants**: `src/v3/compiler/src/emit/rust_target.rs:4296` unconditionally emits `Variant { _0: value }` which is wrong for external tuple variants.

This is a P2 Boundary Discipline violation — a stable lookup rule that *normalizes* duplicate authority instead of dissolving it. Held as a scaffold rather than deleted because the duplicates carry v3-only substrate content (`v3.std.substrate` imports, `ElementRef` / `PortId` references, partitioned `EffectShape`, diagnostic-assertion surface) that cannot yet live under `dsl/std/` — v2 CI recursively ingests `dsl/` and cannot parse v3 grammar. Dissolution trigger: when every module currently duplicated between `dsl/std/` and `src/v3/std/` (or `src/v3/spec/`) has converged to a single canonical home, delete the rank function + mirror policy and remove the duplicate-authority preference rule entirely. After convergence, `declaration_by_name` must resolve against the single surviving authority or fail closed on multiple matches; no rank-based bridge remains. Convergence checklist: (1) `module std.effects` — `dsl/std/effects.dag` ↔ `src/v3/std/effects.dag` (v3 copy imports `v3.std.substrate`, partitions `EffectShape`, uses `ElementRef`); (2) `module std.verification` — `dsl/std/verification.dag` ↔ `src/v3/std/verification.dag` (surfaces are disjoint today: v2 `AssertKind/TestClaim/TestCase` vs v3 `DiagnosticKind / DiagnosticReference / PortStateExpectation`; convergence requires a design call on which surface wins); (3) embedded `http_path` mirror inside `src/v3/std/effects.dag:118-260` (resolves via either staging `http_path.dag` in v3 or rewiring imports to consume `std.http_path` directly once v3-substrate staging lands).

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.

Owner: unassigned (pilot in-flight on Lane H #658); M per service family, contingent on transport capability. -- **Character-level under-consumption in tokenize + syntax authorities (mixed: consumption gap for steps 1+3, substrate gap for step 2 — see Status block below)**: `src/v3/compiler/tokenize.dag` and `dsl/extdeps/languages/dag/syntax.dag` both slice the ASCII/Unicode codepoint space in two parallel non-canonical forms. **Reserved individual codepoints as opaque strings**: `StringEscapeSpec.suffix`, `output_codepoint: Int`, `LocalPunctSpec.pattern`, `string_literal_delimiter`, `line_comment_prefix`, `OperatorSpec.symbol`, `dag_keyword_set` keys — all encode specific codepoints as byte strings. **Reserved codepoint classes as hidden Rust predicates**: `is_ascii_whitespace` / `is_ascii_digit` / `is_ascii_alphabetic` / `is_ascii_alphanumeric` plus a bare `byte == b'_'` `push_str`'d into `regen_tokenize.rs:700,727,750,752`.

Today unit tests ratchet against `u8::is_ascii_*` only. **Next step:** once `char_in_class` is evaluable from the v3 compiler test harness, assert code-point parity on `0..=127` against `byte_matches` and retire the host-stdlib-only ratchet / duplicate sync prose. Same migration gate as deleting `tokenize_char_class.rs` when `regen_tokenize` reads classes from lowered `tokenize.dag`. ### Post-merge debt (2026-04-23 thesis-doc surface — PR #672) From af451620ec27ada3f05d8a4a887e52eb4ef7a6e0 Mon Sep 17 00:00:00 2001 From: Brian Searls Date: Fri, 24 Apr 2026 12:15:07 -0400 Subject: [PATCH 06/77] WIP: gunbc Director --- docs/briefs/r1-selfhosting-manager.md | 8 ++++++ docs/briefs/r1-surface-manager.md | 41 +++++++++++++++++++++++---- docs/briefs/r1-testgen-manager.md | 14 ++++++--- 3 files changed, 54 insertions(+), 9 deletions(-) diff --git a/docs/briefs/r1-selfhosting-manager.md b/docs/briefs/r1-selfhosting-manager.md index 83a34292016..d00b57d0253 100644 --- a/docs/briefs/r1-selfhosting-manager.md +++ b/docs/briefs/r1-selfhosting-manager.md @@ -137,6 +137,14 @@ Lane-owner dispatch status (update as sub-deliverables close): Decisions log (append as they happen): +- 2026-04-24: **T-PB-A reduction wave active.** Non-test hand-Rust shims + retired today: lens_idempotency wrapper (#699), lens_parallelism wrapper + (#715), lens_parallelism compatibility alias (#724), lower pass-through + scaffold + `regen_lower.rs` + non-authoritative `lower_generated.rs` + (#729), infer payload span shim (#730), plus T-PB-A-E (#731) and + T-PB-A-F (#732).

Auditing the 35 files currently in `EXPECTED_HAND_AUTHORED_NON_TEST` shows the "irreducible" tier (build.rs, bootstrap.rs, lib.rs, dag.rs, dag/ports.rs, dag/effects.rs) isn't structurally irreducible — it's just not-yet-migrated substrate authoring. Each of those files can be generated from a `.dag` authority, with the same pattern v3's other generated files already use. + +Zero is achievable. v2 proved the cycle (1 residual was a TESTING.md choice, not a structural limit). v3's substrate is more structural than v2's (lens-as-substrate-declaration, types-as-data, programs-as-data) — so v3 should hit a tighter floor than v2. + +## Design choice — shape (γ) + +Three escalating shapes were considered: + +- **(α)** PB-1's current scope: data-bootstrap of DAG, hand-Rust everything else. Floor ~6-8. +- **(β)** Bootstrap process modeled in `.dag` + a small hand-Rust universal evaluator. Floor ~1-2. +- **(γ)** Substrate, evaluator, and bootstrap process all data. The compiled binary is fully generated; the host runtime (or the build trampoline) is the only thing not in v3's source tree. Floor: 0. + +**This proposal commits to (γ).** Rationale: + +- (β) is a bridge that gets dissolved into (γ); writing the bridge first is wasted work unless mandatory. It's not mandatory — see "First-time bootstrap" below. +- (γ) matches the thesis claim that the substrate is its own subject ([`docs/thesis/self-inspection.md`](thesis/self-inspection.md)). Hand-authored files in v3's source tree contradict that claim at the implementation layer. +- The runtime requirements for (γ) (a small generated evaluator + Cargo trampoline) are themselves generatable. There's no architectural reason to author them by hand. + +## Bootstrap as data — the conceptual core + +The current model: bootstrap is a *process* implemented in hand-Rust (`bootstrap.rs::Dag::new()`) that loads `.dag` source, runs the compiler pipeline, populates a `Dag`. The chicken-egg is "Dag::new() needs the compiler pipeline, which needs Dag::new()." + +The (γ) model: **bootstrap is data.** A `bootstrap.dag` (or equivalent authority) declares: +- Which `.dag` files load in which order +- What state the loaded `Dag` should reach +- What invariants must hold post-load +- What the entry point evaluates to + +The "evaluator" is a small generic interpreter that: +- Reads the bootstrap data +- Constructs the `Dag` +- Hands it to the rest of the compiler (also data) +- Runs `main` (also data) + +The evaluator is itself generated from a `.dag` authority that describes its operations. Per `feedback_compiler_is_dag_processor`: the compiler knows only Node / Conj / Disj / Cardinality / Bit. The evaluator therefore needs only those primitive operations — small. + +**The chicken-egg breaks at the build step**, not at runtime: the previous-generation binary reads the new bootstrap data and emits the new evaluator binary. Same cycle v2 used, applied recursively to the evaluator itself. + +## First-time bootstrap (the genuine N=0 problem) + +Even (γ) has a first-time bootstrap problem: the very first compiled binary has to come from somewhere. + +Three resolutions, in increasing aggressiveness: + +1. **Shipped pre-built binary.** The "first" binary is a release artifact (downloaded via install script, embedded in a published crate, or shipped as a release asset on GitHub). Subsequent bootstraps regenerate from source. Hand-Rust in v3's source tree: 0. Hand-Rust elsewhere (in the install script or release tooling): negligible / not part of v3. + +2. **Universal-runtime crate.** A tiny `gunbc-runtime` crate (published separately, not in v3's source tree) provides the generic evaluator. v3's source tree is `.dag` files + a generated Cargo.toml that depends on `gunbc-runtime`. The runtime crate is hand-authored, but **outside v3's source tree** (cleanly factored as runtime support, not compiler). + +3. **Procedural macro on existing rustc.** A `#[gunbc::data]` attribute (in a tiny crate) tells rustc to interpret the `.dag` content at compile time. Same shape as 2 but different boundary — the macro is the runtime; the rest is data. + +All three give **0 hand-Rust in v3's source tree.** Resolution choice is downstream of taste + ecosystem strategy; doesn't affect the in-tree floor. + +For this proposal: the in-tree floor target is 0 regardless of which N=0 resolution lands. Pick the resolution as a separate decision; it doesn't gate the migration program. + +## Subsumed lanes + +Existing lanes that fold into this program: + +- **PB-1** ([brief](briefs/pb-1-data-driven-bootstrap.md), XXL) — data-driven bootstrap loader. **Non-goals revised:** PB-1's current non-goals (don't delete tokenize/parse/lower/infer/emit; don't go binary-blob; don't change Dag runtime format) were appropriate for the ≤5-floor framing but contradict 0-floor.

Stricter; floor is N (probably 1-3). + +For this proposal: **trampolines are 0 if their content is generated.** The user's stated goal is "0 hand-authored files" — a 1-line `include!()` trampoline that's itself emitted from a `.dag` authority is generated, not hand-authored.

Full arbitrary-command runner support is the PB-Runtime lane's deliverable.

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.

Otherwise emit `Diagnostic::UnhandledDiagnosticPath { op, missing_proof, fix_hints }`. -3. **End-to-end demo: divide.** Smoke + integration test: `let x = a / b` where `b: Int` (no proof) compile-errors with the new diagnostic; `let x = a / b` where `b: Int where b != 0` (proof attached) compiles; `let x = divide_safe(a, b)` returning `Result` compiles.

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.

They derive structurally from the composition of typed primitive operations, exactly the way complexity is derived from `fold` / `descend` / `repeat` composition. Same closed-system mechanism, different property.

Per `substrate.dag`, all computation composes from 5 primitive behaviors: + +`Value | Transform | Branch | Loop | Bind` + +There is no `while(true)`, no unbounded recursion, no `eval(string)`, no raw IO escape hatch. Every form of computation MUST appear as one of these 5. The substrate is closed; the lens domain is closed; **nothing can hide**. + +For effects specifically: every external interaction (db read/write, file IO, network call, log) goes through a typed service primitive declared in `dsl/std/` or `dsl/extdeps/`. Service declarations carry effect signatures (`derive_op_effect` at `effects.dag:722-755` already does this for HTTP). There is no raw effect — no way to perform a side effect without going through a typed primitive. + +## Q2 — Every lens is a compositional fold over the 5 behaviors + +This is the unifying mechanism.

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.

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.

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.

The §0.6 site from the B4 program. Substrate gap: emit helpers (named-alias emission, match emission) need a typed role marker on the `Bind` / `Branch` node attached at lowering time, not inferred from `span.file`. + +The fix is a typed role enum field on `BindNode` / `BranchNode` — populated structurally by the lowering pass when it constructs the node for a helper role.

From 3908349f480f36e28c48d3de5681c0ee9cd942b6 Mon Sep 17 00:00:00 2001 From: Brian Searls Date: Sun, 26 Apr 2026 00:02:14 -0400 Subject: [PATCH 59/77] =?UTF-8?q?docs(briefs):=20R2=20spin-up=20Wave=202?= =?UTF-8?q?=20=E2=80=94=20T-Substrate=20sub-lane=20scoping=20briefs=20(3)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per inbox issue #828: Wave 2 of Director's R2 spin-up authoring queue. Substrate-producer briefs for the 3 T-Substrate sub-lanes consumed by Modeling Manager's Wave 3 worker briefs (gated on these landing). Authored: - r2-substrate-cardinality-for-int-lit-subset.md (M) — produces magnitude carrier consumed by T-Modeling int-lit. Coordinates with PR #806's prior cardinality work; mandatory authority audit guards against #796's rejected IntLiteralMagnitude shape resurfacing. Open design questions: magnitude representation, reconciliation narrowing point, i64::MIN representability. - r2-substrate-nominal-opaque-for-secret-subset.md (M) — produces nominal-opacity carrier consumed by T-Modeling Secret. Open design questions: carrier shape (flag/connective/sealed-accessor), generic-walk discipline, accessor gating. - r2-substrate-parametric-algebra-for-dimensions-subset.md (M) — produces phantom-parameter carrier consumed by T-Modeling Dimension. Open design questions: carrier shape, type-equivalence rule, algebra-method dispatch, lifting/coercion. All three: - Scoped narrowly to their paired R2 consumer; not full substrate-capability lanes. - Mandatory pre-author authority audit per feedback_audit_adjacent_authority_first. - Cross-program readiness signal pattern from #827's manager rework. - Coproduct dissolution receipts required for any new variants. - Open design questions surfaced explicitly so Substrate Manager (or Director pre-spin-up) can resolve at dispatch time. Wave 3 (T-Modeling worker briefs × 4) follows.

Implementation worker briefs for the 3 T-ImpossibleBugs Goal 4 classes, consuming the existing design/scoping briefs as authority. Authored: - r2-impossible-bugs-nested-optional-flatten-worker.md (M) — gated on cardinality refinement substrate (T-Substrate territory adjacent to int-lit / DB-11 alias-where). Implementation: structural normalize of OptionalOf> at type-checker; surface-syntax T?? worker decision (reject vs normalize). Cites t-impossiblebugs-nested-optional-flatten-design.md as authority. - r2-impossible-bugs-unhandled-diagnostic-paths-worker.md (M) — gated on Tier 2 substrate (predicate-entailment infrastructure; distinct from Wave 2 sub-lanes). Three paths: (a) operator dispatch consumes predicate entailment, (b) feedback_totality_by_omission dissolves partial primitives, (c) park. Worker decides at audit time. Cites t-impossiblebugs-unhandled-diagnostic-paths-design.md as authority. - r2-impossible-bugs-unenumerated-effects-worker.md (M) — NO substrate prerequisite per closed-system framing in design doc (#808). Audit- as-existence-check + lens implementation as compositional fold over 5 behaviors; redundancy detection compile-error via referential transparency + reread() escape hatch; path (i/ii) decision on OperationEffect taxonomy retain-vs-retire (default retire). Cites design doc #808 as authority. Cross-cutting: - Each cites prior design/scoping brief as authority (the existing *-design.md / *-worker.md REFRAMED files). - Explicit gating per #827 producer/consumer signal pattern; two briefs gated on substrate, one NOT gated (closed-system). - STOP-AND-ESCALATE includes 'design brief assumptions don't hold' surfacing per feedback_thesis_gate_state_drift. Wave 4 complete. Director's 14-brief queue done; awaiting PM portion (6 manager briefs + §6a + B5/B6/B7) for full R2 spin-up readiness.

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.

From 40e5fda6f43cc191051f905846bff82c4b6f063f Mon Sep 17 00:00:00 2001 From: Brian Searls Date: Sun, 26 Apr 2026 00:36:55 -0400 Subject: [PATCH 70/77] =?UTF-8?q?docs(briefs):=20cardinality-for-int-lit?= =?UTF-8?q?=20=E2=80=94=20close=20as=20redundant;=20existing=20t-substrate?= =?UTF-8?q?-cardinality-int-lit-worker.md=20is=20authority?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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'. Future R2 substrate brief authoring MUST grep docs/briefs/ + dag.rs/ substrate.dag for existing authority first.

Producer (t-substrate-cardinality-int-lit-worker.md) is re-scoped post-wise-pike-578 STOP-AND-ESCALATE: KEEPS LiteralBits::Int(i64) substrate-side; range-facts are String-decimal only; carrier widening (Int128/UInt128/Word128Carrier) deferred to a sibling sub-lane; i64::MIN-as-single-token deferred to that same sibling sub-lane.

Reframed: - Frame: explicit i64-bounded scope per producer's re-scope; this lane is range-facts consumption only, not carrier migration. - Slice rewritten to consumer-side audit + downstream consumer migration (emitters, lens evaluators that pick narrower target types based on literal magnitude post-narrowing). NO IntLit representation widening. - Acceptance updated: lane close is Goal 2 PARTIAL closure (i64-bounded); full close requires the sibling Int128/Word128 sub-lane. - STOP-AND-ESCALATE adds: 'audit reveals consumer that needs Int128/Word128 carrier' → STOP, that consumer waits on sibling sub-lane; do NOT partial-migrate. - Non-goals explicitly: NOT widening LiteralBits::Int(i64), NOT closing i64::MIN-as-single-token. Cross-program signal updated to surface the partial close to R2 Release Manager so they understand Goal 2 closure has two parts: this lane (i64-bounded) + sibling sub-lane (carrier widening).

The substrate gap: fold-template instantiations don't structurally record which template-formal binds the step closure. Lens consumers reach for the file suffix as a stand-in for "this is the standard fold path, the step formal is well-defined." +Per the audit at `lens_apply.rs:22-39`: the `span.file.ends_with("std/algebra.dag")` check at line 38 exists because the bounded R1 interpreter at `eval_std_fold` only certifies certain accumulator/element type shapes. `algebra.dag` folds use `List` accumulators that the interpreter cannot evaluate. The skip prevents the bounded interpreter from running on incompatible shapes; it falls back to a different path. -The fix is to add a typed carrier on fold-template instantiations that names the step-formal `DeclarationRef`. The dispatch becomes a structural query (does this Instantiation carry a `fold_step_formal`?), and the file-suffix check disappears. +The **actual §0.4 dissolution** is a structural eligibility predicate: given a fold `Instantiation`, can the bounded R1 interpreter certify its accumulator + element types? If yes, run; if no, skip via the fallback.
