B4.8 — Phase 2 emit-helper secondary-consumer dissolution

Closes B4.8 from docs/briefs/b4-phase-2-site-dissolution-queue.md (post-B4.3 #824 land).

Audit

Swept all span.file == / .ends_with sites in src/v3/compiler/src/ against the B4.3 carrier (BindEmitParticipation::UserCallable / BranchEmitParticipation):

Site	B4.8 candidate?
`bootstrap.rs:113` (`BOOL_TYPES_FILE`)	No — B4.5 territory (DeclarationRef std-file marker)
`emit_rust_roundtrip_fixtures.rs:166` (`bind.span.file == "runtime_reflection.v3"`)	Yes — selects user Bind by file marker; B4.3 carrier dissolves it
`lens_testgen.rs:203, :520` (verification.dag/substrate.dag)	No — std-decl selection, B4.5/B4.6 territory
`test_runner.rs:1547, :2751` (`decl.span.file == claim.file_name`)	No — variable-to-variable file relation, intrinsic to test-claim resolution; not a sentinel constant

Remaining span.file uses in emit.rs (lines 1083, 1095) pass decl.span.file into source_filtering.excludes(...), which is a structural path-collection filter, not a sentinel-string equality. No migration needed.

Change

src/v3/compiler/src/emit_rust_roundtrip_fixtures.rs:166 — MODULE_RESULT_PORT_IS_PARAM wrapper body migrated from

Behavior::Bind(bind) if !bind.params.is_empty() && bind.span.file == "runtime_reflection.v3"

to the structural carrier:

Behavior::Bind(bind) if bind.name == "id" && bind.emit_participation() == Some(BindEmitParticipation::UserCallable)

This mirrors the pattern B4.3 (#824) introduced for the in-tree emit-helper tests at emit.rs:3166-3220.

Carrier / delete-path note

Carrier: Bind::emit_participation() -> Option<BindEmitParticipation> (pub accessor on dag::Bind, pub enum dag::BindEmitParticipation), authored in B4.3.
Delete path: the file-name sentinel "runtime_reflection.v3" no longer participates in bind selection inside the wrapper; only the input-file argument passed to compile_to_dag retains it (intrinsic SourceSpan input, not a structural query target).
No replacement sentinel string introduced.

Regression

Existing boundary roundtrip test m1_3_emit_rust_test::rustc_roundtrip_emitted_module_compares_reflected_port_ids_in_list_contains exercises the migrated wrapper end-to-end (emit Rust → rustc → run → compare) and now witnesses the structural-dispatch path. Verified locally: passes.

DB-8 / fixed-point

This change touches only wrapper_body string contents in a fixture table consumed by host #[test] harnesses and the r1c_e_emit_gates ExecuteCommand bin; no generated/ratcheted file is regenerated by it. No DB-8 / fixed-point regen required.

Verdict: APPROVE — One-line fixture wrapper change replacing a file-marker + params heuristic with a name + emit_participation() predicate. Narrowly scoped, consistent with dissolving ad-hoc bind-selection markers, no invariant concerns.

Findings

None. The change replaces a fragile selector (span.file == "runtime_reflection.v3" plus non-empty params) with bind.name == "id" and emit_participation() == Some(UserCallable), which uses declared bind identity and participation instead of a file-marker heuristic. Nothing in this one-line fixture string conflicts with INVARIANTS, docs/modeling-discipline.md, CODING.md, or TESTING.md; it stays in the implementation/test-harness layer, not substrate modeling.

Verdict

APPROVE — Single, targeted update in emit_rust_roundtrip_fixtures.rs that dissolves the emit-helper bind selection in the obvious way; no rubric violations observed in the diff.

Exploratory (optional)

If emit_participation() ever returns None for this program while the bind remains user-callable, the fixture would fail loudly via .expect("function bind"); worth keeping an eye on if participation semantics evolve, but that is outside what this diff asserts.

✅ No blocking concerns; this implementation-level fixture change replaces the source-file heuristic with the modeled emit-participation fact.

Verdict: APPROVE

This looks clean. The diff replaces a fixture-local file-marker heuristic with the declared BindEmitParticipation::UserCallable authority plus the bind name, so I don’t see a concrete violation of the pinned invariants or testing guidance.

Verified with cargo test -p v3-compiler rustc_roundtrip_emitted_module_compares_reflected_port_ids_in_list_contains after correcting the package name from v3_compiler to v3-compiler.

Findings: None. The change replaces a file-span heuristic (bind.span.file == "runtime_reflection.v3" plus non-empty params) with the same structural signals the emitter already uses (bind.name == "id" and emit_participation() == Some(BindEmitParticipation::UserCallable)), which matches how emit.rs selects user-callable binds. That is consistent with boundary / single-authority thinking (read a declared fact, not a storage convention) and does not introduce fail-open paths beyond the existing .expect("function bind") on the fixture string. Nothing here touches substrate modeling in a new way; it is roundtrip fixture glue.

Verdict: APPROVE — One-line, narrowly scoped dissolution of the file-marker bind pick in emit_rust_roundtrip_fixtures.rs:166; no rubric violations observed in the diff.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(briefs): align Substrate Produces + Release R2-close acceptance Per gpt-5-5-pro REQUEST_CHANGES on PR #1126 (sha:a9285fce). Two valid findings on coordination-contract internal consistency: 1. **Substrate Produces list omitted ValueBody::Map → PB signal.** The deliverables table at line 94 named ValueBody::Map as an R2 unblocker for PB's kernel_algebra_profile mirror dissolution, but the cross-program "Produces" section listed 5 signals and did not include this one. Same dependency represented in two places with different authority. Fix: add ValueBody::Map carrier read-path/API + arrow-body evaluation as the 6th produced signal targeted at PB Manager; update count from 5 to 6 (also in Reporting-cadence line 150). Remove the "Adjacent territory" note about kernel_algebra_profile being a future sub-lane — substrate already landed via #1017+#1068. 2. **Release R2-close acceptance gate excluded PB from close criterion.** The brief's "Consumes" section correctly named all 6 other managers including PB, but the r2_close_signal_to_director_authored gate at line 103 used "5 R2-archiving managers" (Substrate-prereq / Modeling / Grounding / Impossible-Bugs / Evaluator) — could fire the R2-close signal while PB's R2-scope lanes (Tier 3 mirror dissolutions + kernel_algebra_profile consumer plumbing) are still open. Fix: gate becomes "all 6 other managers' R2-scope lanes complete" with explicit lane-set listed per manager. Distinguish R2-scope completion from manager-archives (Modeling/Impossible-Bugs archive; Substrate/PB continue into R3 with R3-scoped lanes — those don't gate R2 close). Both are P2 single-authority alignments; no scope change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * feat(scripts): manager-brief authority consumer + self-test Per gpt-5-5-pro meta-review on PR #1126: dissolves the recurring "non-live authority consumed as live" pattern that surfaced 5+ times during PR #1078 + #1126 review loops (codex tooling false-positives naming non-existent files / sections; cursor-flagged single-authority drift on Goal numbering + R3 continuation count). v1 covers 4 of gpt-5-5-pro's 5 questions: - **Q1 — cited file existence** — extracts markdown links from each brief, resolves relative paths, fails closed if any cited file doesn't exist on disk. - **Q2 — cited section anchor existence** — for `path#anchor` links, verifies the anchor matches a slugified heading in the target file. - **Q4 — `LANDED via #N` reachability** — two-stage check: (a) fast `git log --grep="(#N)"` for normal merge subjects, (b) fall back to `gh pr view` for squash-merges that drop the suffix (caught a real case for PR #900). Verifies merge SHA is `git merge-base --is-ancestor HEAD`. - **Q5 — cross-brief projection consistency** — extracts manager/lane counts and verifies all briefs that mention a projection agree both cross-brief AND with canonical values from r2-structure.md / r3-structure.md (7 standing managers, 6 other managers, 10 R3 lanes, 7 of 10 Evaluator-gated). Catches drift like "5 R2-archiving managers" vs "all 6 other managers". Q3 (controlled status vocabulary) deferred to v2 — too subjective for a mechanical check; tracked in script header as next narrowing. **Self-test** (`scripts/test-check-manager-brief-authority.sh`): 7 contract assertions — negative cases for each of Q1/Q2/Q4/Q5 (×2) + fail-closed-on-missing-brief + positive case. Mirrors the `test-check-release-doc-authority.sh` pattern. **Wiring:** - Makefile: `manager-brief-authority-check` + `-test` targets; `verify` runs the check. - CI workflow: both check + self-test wired as named steps; check receives `GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}` for the gh API fallback in Q4. **SIGPIPE under pipefail caveat documented inline:** `grep -q .` on a piped `git log` causes pipefail to report failure (grep exits early, git log gets SIGPIPE 141). Workaround: capture output and test `-z`/`-n`. Pinned in Q4 implementation comment. Closes the convergence move gpt-5-5-pro proposed; future review loops that hit the same "non-live authority" class get caught at CI rather than reviewer-by-reviewer prose iteration. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief Q4 — gh-first for CI shallow-clone compat CI failed on the first run of the checker because the workflow uses fetch-depth=1 (shallow clone), so the Q4 fall-back stage's git-log --grep="(#N)" can't see merge history. The two-stage check worked locally because git log had full history; in CI it found nothing on either stage. Restructure Q4 to gh-first: - **Stage 1 (primary):** gh pr view N --json state — returns MERGED for actually-merged PRs regardless of clone depth or squash-merge subject variance. CI passes GH_TOKEN automatically. - **Stage 2 (fallback):** git log --grep — kept for offline dev / auth-blocked environments. In CI with fetch-depth=1 this stage finds nothing; that's why Stage 1 is primary. Reasoning: "is this PR actually merged" is what we want to verify; gh state=MERGED answers it directly. The previous git-log+ancestor check was defense-in-depth, but actually fragile in shallow clones which is the CI default. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief check — set -e + return interaction Per claude-opus-4-7 review on PR #1126: three non-blocking findings addressed. 1. **set -e + return non-zero**: the per-brief driver loop used `check_q1_file_existence "$brief"; rc=$?` — under set -euo pipefail, a function returning non-zero is treated as a failed command and exits the script before the accumulator runs. Result was "stop at first failing brief," not "report all violations in one pass" as intended. Fix: use `|| rc=$?` form (with explicit `rc=0` reset). This keeps set -e from firing on expected-non-zero returns while still capturing the count. 2. **Q2 doc/code mismatch**: header comment promised both `path#anchor` markdown form AND `§"section name"` prose form. Implementation only handled markdown. Trim the comment to match the code; track prose-form in v2 follow-up alongside Q3 status-vocabulary as next narrowing. 3. **Q5 pattern overlap (exploratory)**: claude-opus-4-7 flagged that "standing managers" might substring-match "standing R2 managers". Empirical check shows it doesn't (POSIX regex requires the exact "standing managers" sequence; "R2 " breaks the match). Documented inline; no pattern change needed. 8-bit return-code truncation noted by reviewer is theoretical at current scale (briefs typically have <10 violations) and is now moot since the global `violations` accumulator is plain bash arithmetic; only the per-function `return` is uint8-bounded. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief Q4 — explicit --repo for CI gh detection CI failed Q4 even after gh-first restructure: actions/checkout@v4's shallow clone exposes the remote in a form 'gh pr view' doesn't always auto-detect, so the stage-1 gh call returned empty (no error message in v1 because stderr was redirected to /dev/null) and the stage-2 git-log fallback also failed (shallow clone has no merge history). Three fixes in this commit: 1. **Derive REPO_SLUG from `git config remote.origin.url`** at script start. Falls back to "gunb-ai/gunbc" if origin isn't readable (self-test runs in tmpdir with no remote). 2. **Pass `--repo "$REPO_SLUG"` explicitly to `gh pr view`** so it doesn't have to infer from the cwd's git remote. 3. **Capture gh stderr** to a temp file and surface it in the violation diagnostic. If gh is auth-failing or rate-limited, the violation message now shows why instead of looking like "PR doesn't exist." Both checker + self-test still pass locally. CI should now succeed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ci): grant pull-requests:read for manager-brief authority check The check uses `gh pr view --json state` to verify "LANDED via #N" claims map to MERGED PRs. Default GITHUB_TOKEN scopes only include contents:read; pull-request access fails with: GraphQL: Resource not accessible by integration (repository.pullRequest) Surfaced when the script's stderr-capture fix (ea33aeb) made the actual error message visible — diagnostic improvement paid off immediately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * fix(scripts): manager-brief checker — markdown-bold + heading-strip + Q3 trigger Per gpt-5-5-pro REQUEST_CHANGES on PR #1126 (sha:ea33aeb9). Three findings — one BLOCKING (Q5 was ceremonial on its load-bearing projection), one secondary (heading-strip glob bug), one coverage gap. 1. **Q5 markdown-bold mismatch (BLOCKING).** Live briefs use `Names this manager one of **7** standing R2 managers` — markdown emphasis around the count. The pre-fix regex `[0-9]+ standing R2 managers` required a bare leading digit, so it matched zero claims on every brief. Counts_seen stayed empty → "0 counts seen → silent OK" branch fired → check passed ceremonially. A future drift to `**6** standing R2 managers` would have been invisible. Fix: regex now optionally accepts `**` before and after the digit: `\*?\*?[0-9]+\*?\*? standing R2 managers`. Extraction strips asterisks (`tr -d '*'`) before parsing. Verified on live briefs: $ grep -oE '\*?\*?[0-9]+\*?\*? standing R2 managers' docs/briefs/r2-*-manager.md docs/briefs/r2-evaluator-manager.md:**7** standing R2 managers docs/briefs/r2-grounding-manager.md:**7** standing R2 managers docs/briefs/r2-impossible-bugs-manager.md:**7** standing R2 managers docs/briefs/r2-modeling-manager.md:**7** standing R2 managers docs/briefs/r2-pure-bootstrap-manager.md:**7** standing R2 managers docs/briefs/r2-release-manager.md:**7** standing R2 managers docs/briefs/r2-substrate-manager.md:**7** standing R2 managers Now actually catches all 7 briefs' projections. 2. **Heading-strip glob bug (Q2 secondary).** `${heading##\#* }` is a Bash glob that strips through the LAST space, so "## Goal 7 — Evaluator XL" becomes "XL" instead of "Goal 7 — Evaluator XL". Multi-word heading anchors silently false-fail. Fix: introduced `strip_heading_marker()` helper using sed regex `^#{1,6}[[:space:]]+` for accurate prefix-only stripping. 3. **Self-test fixture format mismatch (coverage gap).** Self-test used bare-digit form ("7 standing R2 managers"); live briefs use markdown-bold ("**7** standing R2 managers"). Fixture proved Q5 for a format the live docs don't use, masking finding 1. Fix: updated all clean + drift fixtures in self-test to use markdown-bold form. Verifies Q5 catches the actual format. 4. **Q3 dissolution trigger (per debt-tracking discipline).** Previous "v2; the next narrowing opportunity" was a future bucket without a checkable trigger. Replaced with concrete trigger: "first reviewer-flagged status-string drift class that Q1/Q2/Q4/Q5 don't catch." Until that surfaces, status vocabulary is captured indirectly via Q5 count-projection consistency. Local checker + self-test still pass after fixes; Q5 now actually fires on live brief content rather than silently passing ceremonial. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts+briefs): manager-brief Q2 prose-form check + align 7 citations Per gpt-5-5-pro BLOCKING on PR #1126 (sha:91b5274fc): Q2 explicitly excluded prose §"section name" citations, but live briefs use those for load-bearing INVARIANTS / r2-structure / design authority claims. The exclusion left 12 real authority drifts uncheckable. **Implements Q2-prose** (in addition to Q2-markdown-anchor): For each `§"quoted section"` or `§AnchorToken` in a brief: 1. Compute the prefix BEFORE this citation (running prefix; the bug in v0 was using before-first-§ for every iteration, so subsequent citations on the same line resolved against the first link's target instead of their own). 2. Find the most recent markdown link `[text](path)` in the prefix — that's the cited file. Fall back to bare `<NAME>.md` token via `resolve_authority_file()` (tries `$ROOT/`, `$ROOT/docs/`, `$ROOT/docs/thesis/`, `$ROOT/docs/briefs/`). 3. `grep -F` for the section text in the cited file. Permissive substring match (vs Q2-markdown's slug match) — accepts paraphrased section names while still catching the load-bearing "section deleted" failure mode. **Caught 12 real drifts on first run** — all now fixed: - r2-evaluator-manager.md: §"Goal 7 — Evaluator XL" + §"Evaluator Manager (added 2026-04-28 as Goal 7)" → §"Evaluator Manager (added 2026-04-28 amendment)" (matches r2-structure.md:159 actual heading) - r2-grounding-manager.md: §"Tier 1 — Structural correctness — Grounding completeness" → §"Tier 1 — Structural correctness" (matches THESIS.md:168 actual prose) - r2-impossible-bugs-manager.md (×2): §"R2 manager continuation" → §"Manager structure" (matches r3-structure.md:103 actual heading) - r2-impossible-bugs-manager.md: §Q1-Q3 + §Q6 → §Q1, §Q2, §Q3 + §Q6 (range citation didn't match anything literal; expand to discrete) - r2-release-manager.md (×2): §"R2 manager continuation" → §"Manager structure" - r2-release-manager.md (×2): §v2-guardrail-requirement-3 → §"v2 guardrail requirements" (matches r2-structure.md:490 body) - r2-substrate-manager.md: §"R3 lane structure" → §"Lane structure" (matches r3-structure.md:86 actual heading) Local checker + self-test still pass after fixes. Reinforces gpt-5-5-pro's earlier meta-observation: a checker that names a discipline but doesn't enforce it on the live format is documented cheating. Q2-prose closes that gap; the briefs' authority citations now have to match section text that actually exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(scripts): manager-brief — mktemp gh-stderr + Q1 false-pos trigger Per claude-opus-4-7 APPROVE-with-exploratory-observations on PR #1126 (sha:91b5274f). Two non-blocking cleanups landed. 1. **gh-stderr capture: $$ → mktemp.** Previous form used `/tmp/gh-stderr-$$` which is fine in CI but a crashed run on a shared dev box could leak the file. `mktemp` gives a unique path + paired cleanup in scope. 2. **Q1 false-positive trigger documented.** Q1 currently treats every `](path)` as a filesystem reference. Markdown reference- style link definitions and code-block examples containing `](foo)` would false-positive.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(briefs): R2 manager-brief status refresh against landed PRs Pre-spawn implementation work has progressed materially while #1078 was in flight; managers spawning today would otherwise dispatch against work that's already landed. Refresh per-manager status tables to reflect current main: - **Substrate:** ValueBody::Map landed (#1017 + #1068 tightening); NominalOpacity fail-closed field-projection enforcement (#937); B4.8 Phase-2 site dissolution landed (#1069); B4.2 first-consumer wiring landed; T-Cost-Dimension fail-closed precedent (#1003). - **Grounding:** Rust IntegerRangeFact mirror dissolved (#1005); Python primitives.dag landed (#1080); Go primitives tranche 1 + additional (ac765ce + #1046); T-Ground-Engine Phase 2 slice 1 (c0cc8b2) noted as pre-cascade footprint queued for cleanup wave per design-emission-model.md option (c). - **Impossible-Bugs:** all 3 main implementations LANDED pre-spawn (nested-optional flatten #890 + #962 follow-ups; Int/Int totality- by-omission first slice #969; unenumerated effects lens landing #971). Day-1 work is class-close completion + sibling totalization dispatch (indexing/quotient/remainder), not initial implementation. - **Pure Bootstrap:** kernel_algebra_profile substrate met via #1017 + #1068 (consumer plumbing now the remaining R2 work, dispatchable Day-1); T-PB-Runtime ExecuteCommand typed-outcome hardening (#1049) + T-PB-B boundary coverage (#1082) advanced PB-Runtime foundation for R3 lens_apply.rs retirement gate. - **Modeling:** Secret<T> producer side substantially advanced (#900 carrier + #937 fail-closed enforcement); tokenizer charclass scanner-order retype landed pre-cascade (242c65d); SourceFiltering canonical authority precedent (#1004). - **Release:** initial closure-ledger snapshot now reflects all pre-spawn landings (Impossible-Bugs/Substrate/Ground/PB-Runtime). Evaluator brief unchanged — new lane added 2026-04-28; nothing landed yet (gated on PR-A through PR-E design lock cadence). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(briefs): align Substrate Produces + Release R2-close acceptance Per gpt-5-5-pro REQUEST_CHANGES on PR #1126 (sha:a9285fce). Two valid findings on coordination-contract internal consistency: 1. **Substrate Produces list omitted ValueBody::Map → PB signal.** The deliverables table at line 94 named ValueBody::Map as an R2 unblocker for PB's kernel_algebra_profile mirror dissolution, but the cross-program "Produces" section listed 5 signals and did not include this one. Same dependency represented in two places with different authority. Fix: add ValueBody::Map carrier read-path/API + arrow-body evaluation as the 6th produced signal targeted at PB Manager; update count from 5 to 6 (also in Reporting-cadence line 150). Remove the "Adjacent territory" note about kernel_algebra_profile being a future sub-lane — substrate already landed via #1017+#1068. 2. **Release R2-close acceptance gate excluded PB from close criterion.** The brief's "Consumes" section correctly named all 6 other managers including PB, but the r2_close_signal_to_director_authored gate at line 103 used "5 R2-archiving managers" (Substrate-prereq / Modeling / Grounding / Impossible-Bugs / Evaluator) — could fire the R2-close signal while PB's R2-scope lanes (Tier 3 mirror dissolutions + kernel_algebra_profile consumer plumbing) are still open. Fix: gate becomes "all 6 other managers' R2-scope lanes complete" with explicit lane-set listed per manager. Distinguish R2-scope completion from manager-archives (Modeling/Impossible-Bugs archive; Substrate/PB continue into R3 with R3-scoped lanes — those don't gate R2 close). Both are P2 single-authority alignments; no scope change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * feat(scripts): manager-brief authority consumer + self-test Per gpt-5-5-pro meta-review on PR #1126: dissolves the recurring "non-live authority consumed as live" pattern that surfaced 5+ times during PR #1078 + #1126 review loops (codex tooling false-positives naming non-existent files / sections; cursor-flagged single-authority drift on Goal numbering + R3 continuation count). v1 covers 4 of gpt-5-5-pro's 5 questions: - **Q1 — cited file existence** — extracts markdown links from each brief, resolves relative paths, fails closed if any cited file doesn't exist on disk. - **Q2 — cited section anchor existence** — for `path#anchor` links, verifies the anchor matches a slugified heading in the target file. - **Q4 — `LANDED via #N` reachability** — two-stage check: (a) fast `git log --grep="(#N)"` for normal merge subjects, (b) fall back to `gh pr view` for squash-merges that drop the suffix (caught a real case for PR #900). Verifies merge SHA is `git merge-base --is-ancestor HEAD`. - **Q5 — cross-brief projection consistency** — extracts manager/lane counts and verifies all briefs that mention a projection agree both cross-brief AND with canonical values from r2-structure.md / r3-structure.md (7 standing managers, 6 other managers, 10 R3 lanes, 7 of 10 Evaluator-gated). Catches drift like "5 R2-archiving managers" vs "all 6 other managers". Q3 (controlled status vocabulary) deferred to v2 — too subjective for a mechanical check; tracked in script header as next narrowing. **Self-test** (`scripts/test-check-manager-brief-authority.sh`): 7 contract assertions — negative cases for each of Q1/Q2/Q4/Q5 (×2) + fail-closed-on-missing-brief + positive case. Mirrors the `test-check-release-doc-authority.sh` pattern. **Wiring:** - Makefile: `manager-brief-authority-check` + `-test` targets; `verify` runs the check. - CI workflow: both check + self-test wired as named steps; check receives `GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}` for the gh API fallback in Q4. **SIGPIPE under pipefail caveat documented inline:** `grep -q .` on a piped `git log` causes pipefail to report failure (grep exits early, git log gets SIGPIPE 141). Workaround: capture output and test `-z`/`-n`. Pinned in Q4 implementation comment. Closes the convergence move gpt-5-5-pro proposed; future review loops that hit the same "non-live authority" class get caught at CI rather than reviewer-by-reviewer prose iteration. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief Q4 — gh-first for CI shallow-clone compat CI failed on the first run of the checker because the workflow uses fetch-depth=1 (shallow clone), so the Q4 fall-back stage's git-log --grep="(#N)" can't see merge history. The two-stage check worked locally because git log had full history; in CI it found nothing on either stage. Restructure Q4 to gh-first: - **Stage 1 (primary):** gh pr view N --json state — returns MERGED for actually-merged PRs regardless of clone depth or squash-merge subject variance. CI passes GH_TOKEN automatically. - **Stage 2 (fallback):** git log --grep — kept for offline dev / auth-blocked environments. In CI with fetch-depth=1 this stage finds nothing; that's why Stage 1 is primary. Reasoning: "is this PR actually merged" is what we want to verify; gh state=MERGED answers it directly. The previous git-log+ancestor check was defense-in-depth, but actually fragile in shallow clones which is the CI default. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief check — set -e + return interaction Per claude-opus-4-7 review on PR #1126: three non-blocking findings addressed. 1. **set -e + return non-zero**: the per-brief driver loop used `check_q1_file_existence "$brief"; rc=$?` — under set -euo pipefail, a function returning non-zero is treated as a failed command and exits the script before the accumulator runs. Result was "stop at first failing brief," not "report all violations in one pass" as intended. Fix: use `|| rc=$?` form (with explicit `rc=0` reset). This keeps set -e from firing on expected-non-zero returns while still capturing the count. 2. **Q2 doc/code mismatch**: header comment promised both `path#anchor` markdown form AND `§"section name"` prose form. Implementation only handled markdown. Trim the comment to match the code; track prose-form in v2 follow-up alongside Q3 status-vocabulary as next narrowing. 3. **Q5 pattern overlap (exploratory)**: claude-opus-4-7 flagged that "standing managers" might substring-match "standing R2 managers". Empirical check shows it doesn't (POSIX regex requires the exact "standing managers" sequence; "R2 " breaks the match). Documented inline; no pattern change needed. 8-bit return-code truncation noted by reviewer is theoretical at current scale (briefs typically have <10 violations) and is now moot since the global `violations` accumulator is plain bash arithmetic; only the per-function `return` is uint8-bounded. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts): manager-brief Q4 — explicit --repo for CI gh detection CI failed Q4 even after gh-first restructure: actions/checkout@v4's shallow clone exposes the remote in a form 'gh pr view' doesn't always auto-detect, so the stage-1 gh call returned empty (no error message in v1 because stderr was redirected to /dev/null) and the stage-2 git-log fallback also failed (shallow clone has no merge history). Three fixes in this commit: 1. **Derive REPO_SLUG from `git config remote.origin.url`** at script start. Falls back to "gunb-ai/gunbc" if origin isn't readable (self-test runs in tmpdir with no remote). 2. **Pass `--repo "$REPO_SLUG"` explicitly to `gh pr view`** so it doesn't have to infer from the cwd's git remote. 3. **Capture gh stderr** to a temp file and surface it in the violation diagnostic. If gh is auth-failing or rate-limited, the violation message now shows why instead of looking like "PR doesn't exist." Both checker + self-test still pass locally. CI should now succeed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ci): grant pull-requests:read for manager-brief authority check The check uses `gh pr view --json state` to verify "LANDED via #N" claims map to MERGED PRs. Default GITHUB_TOKEN scopes only include contents:read; pull-request access fails with: GraphQL: Resource not accessible by integration (repository.pullRequest) Surfaced when the script's stderr-capture fix (ea33aeb) made the actual error message visible — diagnostic improvement paid off immediately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * fix(scripts): manager-brief checker — markdown-bold + heading-strip + Q3 trigger Per gpt-5-5-pro REQUEST_CHANGES on PR #1126 (sha:ea33aeb9). Three findings — one BLOCKING (Q5 was ceremonial on its load-bearing projection), one secondary (heading-strip glob bug), one coverage gap. 1. **Q5 markdown-bold mismatch (BLOCKING).** Live briefs use `Names this manager one of **7** standing R2 managers` — markdown emphasis around the count. The pre-fix regex `[0-9]+ standing R2 managers` required a bare leading digit, so it matched zero claims on every brief. Counts_seen stayed empty → "0 counts seen → silent OK" branch fired → check passed ceremonially. A future drift to `**6** standing R2 managers` would have been invisible. Fix: regex now optionally accepts `**` before and after the digit: `\*?\*?[0-9]+\*?\*? standing R2 managers`. Extraction strips asterisks (`tr -d '*'`) before parsing. Verified on live briefs: $ grep -oE '\*?\*?[0-9]+\*?\*? standing R2 managers' docs/briefs/r2-*-manager.md docs/briefs/r2-evaluator-manager.md:**7** standing R2 managers docs/briefs/r2-grounding-manager.md:**7** standing R2 managers docs/briefs/r2-impossible-bugs-manager.md:**7** standing R2 managers docs/briefs/r2-modeling-manager.md:**7** standing R2 managers docs/briefs/r2-pure-bootstrap-manager.md:**7** standing R2 managers docs/briefs/r2-release-manager.md:**7** standing R2 managers docs/briefs/r2-substrate-manager.md:**7** standing R2 managers Now actually catches all 7 briefs' projections. 2. **Heading-strip glob bug (Q2 secondary).** `${heading##\#* }` is a Bash glob that strips through the LAST space, so "## Goal 7 — Evaluator XL" becomes "XL" instead of "Goal 7 — Evaluator XL". Multi-word heading anchors silently false-fail. Fix: introduced `strip_heading_marker()` helper using sed regex `^#{1,6}[[:space:]]+` for accurate prefix-only stripping. 3. **Self-test fixture format mismatch (coverage gap).** Self-test used bare-digit form ("7 standing R2 managers"); live briefs use markdown-bold ("**7** standing R2 managers"). Fixture proved Q5 for a format the live docs don't use, masking finding 1. Fix: updated all clean + drift fixtures in self-test to use markdown-bold form. Verifies Q5 catches the actual format. 4. **Q3 dissolution trigger (per debt-tracking discipline).** Previous "v2; the next narrowing opportunity" was a future bucket without a checkable trigger. Replaced with concrete trigger: "first reviewer-flagged status-string drift class that Q1/Q2/Q4/Q5 don't catch." Until that surfaces, status vocabulary is captured indirectly via Q5 count-projection consistency. Local checker + self-test still pass after fixes; Q5 now actually fires on live brief content rather than silently passing ceremonial. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(scripts+briefs): manager-brief Q2 prose-form check + align 7 citations Per gpt-5-5-pro BLOCKING on PR #1126 (sha:91b5274fc): Q2 explicitly excluded prose §"section name" citations, but live briefs use those for load-bearing INVARIANTS / r2-structure / design authority claims. The exclusion left 12 real authority drifts uncheckable. **Implements Q2-prose** (in addition to Q2-markdown-anchor): For each `§"quoted section"` or `§AnchorToken` in a brief: 1. Compute the prefix BEFORE this citation (running prefix; the bug in v0 was using before-first-§ for every iteration, so subsequent citations on the same line resolved against the first link's target instead of their own). 2. Find the most recent markdown link `[text](path)` in the prefix — that's the cited file. Fall back to bare `<NAME>.md` token via `resolve_authority_file()` (tries `$ROOT/`, `$ROOT/docs/`, `$ROOT/docs/thesis/`, `$ROOT/docs/briefs/`). 3. `grep -F` for the section text in the cited file. Permissive substring match (vs Q2-markdown's slug match) — accepts paraphrased section names while still catching the load-bearing "section deleted" failure mode. **Caught 12 real drifts on first run** — all now fixed: - r2-evaluator-manager.md: §"Goal 7 — Evaluator XL" + §"Evaluator Manager (added 2026-04-28 as Goal 7)" → §"Evaluator Manager (added 2026-04-28 amendment)" (matches r2-structure.md:159 actual heading) - r2-grounding-manager.md: §"Tier 1 — Structural correctness — Grounding completeness" → §"Tier 1 — Structural correctness" (matches THESIS.md:168 actual prose) - r2-impossible-bugs-manager.md (×2): §"R2 manager continuation" → §"Manager structure" (matches r3-structure.md:103 actual heading) - r2-impossible-bugs-manager.md: §Q1-Q3 + §Q6 → §Q1, §Q2, §Q3 + §Q6 (range citation didn't match anything literal; expand to discrete) - r2-release-manager.md (×2): §"R2 manager continuation" → §"Manager structure" - r2-release-manager.md (×2): §v2-guardrail-requirement-3 → §"v2 guardrail requirements" (matches r2-structure.md:490 body) - r2-substrate-manager.md: §"R3 lane structure" → §"Lane structure" (matches r3-structure.md:86 actual heading) Local checker + self-test still pass after fixes. Reinforces gpt-5-5-pro's earlier meta-observation: a checker that names a discipline but doesn't enforce it on the live format is documented cheating. Q2-prose closes that gap; the briefs' authority citations now have to match section text that actually exists. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(scripts): manager-brief — mktemp gh-stderr + Q1 false-pos trigger Per claude-opus-4-7 APPROVE-with-exploratory-observations on PR #1126 (sha:91b5274f). Two non-blocking cleanups landed. 1. **gh-stderr capture: $$ → mktemp.** Previous form used `/tmp/gh-stderr-$$` which is fine in CI but a crashed run on a shared dev box could leak the file. `mktemp` gives a unique path + paired cleanup in scope. 2. **Q1 false-positive trigger documented.** Q1 currently treats every `](path)` as a filesystem reference. Markdown reference- style link definitions and code-block examples containing `](foo)` would false-positive. No briefs use either form today; added DISSOLUTION TRIGGER comment naming the condition that would force context-aware extraction (skip fenced code blocks + reference definitions). The third observation (squash-merge for the WIP: Gunbc PM commits) is a merge-time decision; PR-level chore.

Live brief usage caught: §4 — r2-evaluator/grounding/impossible-bugs/modeling/pure-bootstrap §6a — r2-modeling-manager.md (cite of design-substrate-carrier-port-program §6a) §0.7 — r2-pure-bootstrap-manager.md (cite of debt-paydown-synthesis §0.7) §5 — r2-release-manager.md All previously skipped → "Q2 (prose §) resolved" was vacuously true on those lines. Fix: regex `§[A-Za-z][A-Za-z0-9._-]*[A-Za-z0-9]|§[A-Za-z]` → `§[A-Za-z0-9][A-Za-z0-9._-]*[A-Za-z0-9]|§[A-Za-z0-9]` (extends [A-Za-z]-leading to [A-Za-z0-9]-leading; quoted form unchanged). Documented limitation: short digit-only tokens like §4 resolve permissively because grep -F "4" matches anywhere; multi-character tokens like §6a are discriminating. Self-test gap (also flagged): added `test_negative_q2_missing_prose_numeric_section` using §99zzz (digit-leading, multi-char so substring match doesn't trivially pass). Verifies regex extraction triggers Q2-prose violation on digit-leading citation drift. Self-test now: 9 contract assertions (7 negative + 1 positive + 1 fail-closed-on-missing-brief). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): consume Tier 1 design locks 1+2+3 from #1129 Director landed Items 1+2+3 design locks together via #1129 (`e1afabe47`): - Item 1 (Q1 asymmetric bound algebra) — `docs/design-emission-model.md` §"Q1 — `BoundDeclaration` substrate type" - Item 2 (reflection completeness) — NEW `docs/design-reflection-completeness.md` - Item 3 (Q6.5 two-layer diagnostic-kind) — `docs/design-lens-framework.md` §"Q6.5 — Two-layer authority for diagnostic kinds" Per agreed PM role on inbox #828: as each design-lock doc lands, PM consumes the lock into worker brief updates (statuses move from PENDING/gated → LIVE; cited authority anchors verified by the manager-brief authority checker). Mostly mechanical. Brief updates: - **Substrate** (3 sites): T-Substrate-Lens-Primitive flips from "gated on PR-K" to "Q6/Q6.5/Q7/Q8 LANDED via #1129; ready to dispatch"; "Diagnostic-kind extensibility (Q6 lock)" replaced with the locked Q6.5 two-layer authority cite (Layer 1 closed sum Substrate-owned; Layer 2 lens-instance via inhabitance; additive widening of `Diagnostic.kind` named). - **Evaluator** (5 sites): "Lens application gated on PR-C" → cites the landed reflection-completeness doc; PR-C row in cadence table flips to LANDED; Q6 disposition becomes Q6+Q6.5 with explicit cite to design-lens-framework.md §Q6.5; "Reflection completeness lives in PR-C" → "lives in design-reflection-completeness.md (LANDED via #1129)"; PR-C worker brief in pending list crossed out as superseded. - **Modeling** (1 site): status header now cites Q1 lock landing with explicit anchor; int-lit item already references Interval<D> via PR-PreF. - **Grounding** (2 sites): T-Ground-Diagnostic lane and Substrate- Manager-cross-program-dependency cite Q6.5 — clarifies lane is Layer-1 consumer (not Layer-2 author), no cross-manager handoff. - **Pure Bootstrap** (1 site): Q6 disposition becomes Q6+Q6.5 + reflection-completeness cite added (load-bearing for R3-T- LensProducer-Retirement per design-reflection-completeness.md §"Cascade and gates" §7.3). - **Impossible-Bugs** (1 site): Q6 cite becomes Q6+Q6.5; classes consume Layer 1, not author Layer 2. Verified: `bash scripts/check-manager-brief-authority.sh` passes all 7 briefs (Q1/Q2-md/Q2-prose/Q4/Q5); 9 contract assertions in self-test still pass. Note: one brief edit required restructuring (modeling-manager.md:3) because the original cite put §"section" inside the markdown link's display text, while the heuristic finds the rightmost `](path)` BEFORE the §. Moved cite outside the link to align: `[file.md](path) §"section"`. Same pattern as other landed cites; the checker enforces it structurally. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(scripts): manager-brief — concrete dissolution trigger for short-digit § limitation Per codex APPROVE_WITH_COMMENTS on PR #1156 (sha:00540f36): the short digit-only § resolve-permissively limitation was documented and bounded but lacked a concrete dissolution trigger. Updated to match Q3 dissolution-trigger discipline: trigger fires on first reviewer-flagged stale `§N` (single-digit) citation that survives the substring check because the digit appears elsewhere in the target file. At that point the check tightens to require structural context — match `§N` only if the target has a heading `## N`, `### N`, etc. or numbered-list item at column 0. Until that surfaces, multi-character disambiguation is the load-bearing discriminator (and live briefs predominantly use multi-char forms — §P1, §Q6, §Q6.5, §"Lane structure" — so single-digit `§4` citations are uncommon). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(design): consume Q6.5 lock in worked examples + r2-structure Q6 row Per Director (zesty-bear-812) endorsement on inbox #828: fold the design-doc Q6.5-consumption edits originally drafted in PR #1137 (jolly-ram-908) into the canonical consumption PR. Single-sourced consumption story; #1137 ends up as a clean no-op redirect. 8 lens-framework worked-example reframes + 1 r2-structure Q6 row update. All consume the Q6.5 two-layer authority disposition landed via #1129: **design-lens-framework.md (8 sites):** - §"Lens<TenantFlow>" `validate(dag, set)`: "new CompilerDiagnosticKind variant" → "lens-local diagnostic-kind declaration" - §"Lens<IFC>" `validate(dag, label)`: same reframe for IFCDowngradeViolation - §"D5 Failure modes": "appropriate CompilerDiagnosticKind variant (lens instances may extend CompilerDiagnosticKind...)" → "appropriate lens-local diagnostic-kind declaration" - §Q6 alternative (d): "pushes structural failure data into Diagnostic.kind (which is CompilerDiagnosticKind sum type — already extends per-instance per feedback_state_space_vs_behavioral_invariants)" → "pushes structural failure data into lens-local Diagnostic.kind declarations" - §Q6 anti-bridge claim renaming `no_string_parsing_in_witness_consumers` description: "Diagnostic.kind extensions" → "lens-local Diagnostic.kind declarations" - §Q6 Recommendation (d): "encode into Diagnostic.kind sum-type variants. Lens instances ... extend CompilerDiagnosticKind with their own variants" → "encode into lens-local Diagnostic.kind declarations. Lens instances ... declare their own kinds beside the lens instance" - §Q6 DECISION line: "(c)/(d) hybrid — Witness<C> stays as-is; rich structural validation failures encode into Diagnostic.kind extensions via the lens-framework's structural inhabitance" → same with "lens-local Diagnostic.kind declarations"; date stamp augmented with "refined 2026-04-29" - §Q6 Director's framing #1: "CapabilityViolation as a CompilerDiagnosticKind variant is uniform" → "CapabilityViolation as a lens-local diagnostic-kind declaration is uniform" **r2-structure.md (1 site):** §"Q1-Q8 disposition" Q6 row updated to match design-lens-framework's locked language: "encode into Diagnostic.kind extensions via lens-framework's structural inhabitance" → "encode into lens-local Diagnostic.kind declarations via lens-framework structural inhabitance, not into the closed compiler-core CompilerDiagnosticKind sum". These edits are *editorial* — the Q6.5 lock at design-lens-framework.md §"Q6.5 — Two-layer authority for diagnostic kinds" remains the canonical authority; this just aligns the worked examples + r2- structure summary row with that canonical phrasing so future readers don't see the older "extends CompilerDiagnosticKind" framing in worked examples and assume it survived. Verified: manager-brief authority check passes (7 briefs / 0 violations); 9 contract assertions in self-test pass; release-doc authority check passes. Per inbox #828 + #1130 coordination: jolly-ram-908 confirmed PR #1137 will close as redundant once #1156 lands (the brief edits were already absorbed by my prior consumption pass; these design-doc edits are the residual that's now folded in).

Non-blocking follow-ups from PR #1166 review: - Gate-string convention note: descriptive placeholders until ROADMAP alignment pass; lane-owning manager is canonical-name authority. - in-flight vs not-started convention: requires active worker PR or cited substrate landings; "worker brief authored" alone stays not-started. Flips Impossible-Bugs nested-optional + unhandled- diagnostic-paths rows back to not-started. - T-Ground-Pilot row: gate corrected to pilot_inhabitance_routing_ stability_landed; last signal cites #765 (per r2-grounding-manager). - B4 narrative: split #1069 onto Phase 2 row; Phase 1 row keeps only B4.2 first-consumer wiring as last signal. - R2-close clause: explicit that R3-continuation rows do NOT gate r2_close_signal_to_director_authored. - Replace line-136 anchor in r2-structure.md citation with section + quoted phrase (rot-resistant per code-reviewer exploratory note).

* docs(r2): land R2 closure ledger + signal-receiver protocol Adds docs/r2-closure-ledger.md as the standing artifact satisfying r2_closure_ledger_landed acceptance gate from the R2 Release Manager brief. Carries: - Per-manager rows (Substrate / Modeling / Grounding / Impossible-Bugs / Pure Bootstrap / Evaluator) at lane / sub-lane / item / class granularity matching each manager's brief. - T-LensProducer-Retirement as one row with 3 internal sub-gates (Director cascade Item 8 — sub-progress, not three lanes). - Reserved "R1 Residual (absorbed)" surface so R1C-B strict-receipt rows (sleek-pike #1164 / bold-wolf #1163) and R1 residual sweep rows merge in without table reshape. - Signal-receiver protocol: cross-manager queue channel; receipt = ledger row update + queue ack; cadence touchpoints with velocity-tripwire ≥3:1 surfacing to Director per INVARIANTS §P5(c). Release Manager remains single ledger owner; lane-level structural gates stay with lane-owning managers. Wires the brief: r2-release-manager.md owned deliverable #9 and the r2_closure_ledger_landed acceptance gate now point to the new doc. Minimal blast radius — no edits to docs/r2-structure.md per dispatch guidance. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r2): address RM review on closure ledger Non-blocking follow-ups from PR #1166 review: - Gate-string convention note: descriptive placeholders until ROADMAP alignment pass; lane-owning manager is canonical-name authority. - in-flight vs not-started convention: requires active worker PR or cited substrate landings; "worker brief authored" alone stays not-started.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r2): align v2-retirement timing with r2-structure authority Two surface mentions in r2-release-manager.md said v2 retirement operates post-R2; r2-structure.md §"R2 Release Manager" is single authority and locks it as post-R3 (moved with the R3 structured- program reframe). Inline review on PR #1166 flagged the dual- authority risk. Aligns both spots; no edits to r2-structure.md.
