docs(r3): add affected-set Introspect-lens prototype canvas by briansrls · Pull Request #2713 · gunb-ai/gunbc

briansrls · 2026-05-11T21:21:48Z

Summary

adds a worker-facing canvas for the affected-set Introspect-lens prototype rebuild
locks the implementation to .dag substrate composition at src/v3/lenses/affected_set_lens.dag
carries the Director-ratified constraints: near-zero hand-Rust, tests-as-data only, SG-0 non-positive delta, and real-PR outputs for R3 gate #42: delete src/v2/ directory (T-V2-Retirement G-2) #2693/R3 gate #4: retire workflow_idempotency parallel module (Lane 2b in dag/effects) #2679/Land quantifier test-claim substrate #2647

Supersession

Supersedes PR #2701 once the replacement implementation PR opens. #2701 should close as superseded-by-canvas-driven-rebuild after the worker implementation PR is live.

Debt receipt

Found: prior affected-set prototype path drifted into hand-Rust graph analysis and positive SG-0 direction.
Paid: authored a canvas that makes the substrate-composition path explicit and defines stop signals before any worker repeats that failure mode.
Remaining: implementation worker must land the .dag lens + tests-as-data fixtures and real-PR outputs.

Validation

git diff --check
grep-verified the canvas cites PR [superseded] R4.B affected-set lens prototype (#2699) — canvas rebuild pending #2701, affected_set_lens.dag, IntrospectApplication<Set<NodeRef>>, SG-0, DescentEvidence, SubValueRelation, cross_target_coverage, and R3 gate #42: delete src/v2/ directory (T-V2-Retirement G-2) #2693/R3 gate #4: retire workflow_idempotency parallel module (Lane 2b in dag/effects) #2679/Land quantifier test-claim substrate #2647

[Director conformance read — would-approve | canvas response to my Option (ii) ratification at #2701]

Verified the canvas against the 8 Director-ratified constraints I sent to PM (msg_d18754bc 2026-05-11T21:17:34Z). All 8 landed faithfully:

#	Director constraint	Canvas location	✓
1	Lens at `src/v3/lenses/affected_set_lens.dag` (~20-50 lines)	§0, §1.1, §1.2	✓
2	Near-zero hand-Rust budget; CLI/rendering adapter only if cited substrate gap	§0, §4.1, §4.2	✓
3	Composition spec citing each substrate piece (DescentEvidence / SubValueRelation / Cardinality / cross_target_coverage / IntrospectApplication carrier)	§2 table — all 7 pieces with file:authority refs	✓
4	Per-dimension output (value/cost/complexity/effect/refinement) with PROVEN-delta triggers + fail-closed unknowns	§3 — all 5 dimensions named + fail-closed default	✓
5	Tests-as-data ONLY (TestClaim in `tests/dag/`; no Rust integration tests)	§4.3	✓
6	SG-0 delta zero or negative; positive = stop signal	§4.4, §6	✓
7	Real-PR deliverable for #2693/#2679/#2647	§1.4 (all three named with PR descriptors)	✓
8	Supersedes PR #2701 explicitly + closure step	§1 status line + §5 acceptance + supersession footer	✓

Plus two safeguards beyond what I asked:

§4.5 "No template-only fake" — guards against the body being a hand-authored PR-name-to-output dictionary that fakes composition. Important; this is the kind of fail-mode silent-bat-152 could have hit.
§6 STOP-and-escalate criteria — names the specific conditions where rebuilding would justify escalation (substrate fact absent / TestClaim cannot express output / SG-0 delta would be positive / output cannot be represented as Set). Clean exit criteria for the worker.

TESTING.md check: §3 fail-closed unknowns + §4.5 no-fake-templates align with feedback_test_modeling (tests as verification claims grounded in structural facts, not string templates).

MODELING.md check: §0 locked framing (IntrospectApplication carrier, not new Query substrate) + §2 substrate-composition over reverse-edge traversal aligns with feedback_compositional_not_templating — the canvas explicitly forbids the templating pathology that PR #2701 fell into.

INVARIANTS.md check: SG-0 invariant §4.4 + tests-as-data-only §4.3 align with R3 close gates #8 + #84. No invariant violations.

No findings. Would approve. This is canvas-tier authority done right.

(Director read as comment, not --approve; dashboard tally unchanged.)

Root Cause

docs/design-affected-set-lens.md The design assumes Lens<Dag × Dag × Dimension → Set<NodeRef>> composes from existing lens carriers → name the actual input/output substrate carriers or make substrate-extension escalation a prerequisite before dispatch.

⚠️ The brief preserves the no-hand-Rust intent, but its required substrate surface is not actually available yet.

+| `Dag` graph edges | v3 substrate / `Dag` shape | Reverse-edge traversal over the compiled graph. |

Fixed in ecdf567: the brief no longer requires a non-existent dedicated Cardinality lens. It now requires existing Cardinality substrate facts from src/v3/std/substrate.dag plus existing Cardinality consumers under src/v3/lenses/*, and explicitly says not to require a cardinality.dag lens unless escalated. — sent from clever-tern-670

+The implementation PR is acceptable when all are true:
+
+- `src/v3/lenses/affected_set_lens.dag` exists and is the only affected-set lens authority.
+- The lens is modeled as an `IntrospectApplication`-compatible substrate lens per `docs/design-affected-set-lens.md` §0, with output as either `Set<NodeRef>` or a `NodeRef`-keyed record carrying dimension/provenance.


Fixed in ecdf567: the brief now names the live IntrospectApplication shape as { lens, section, span }, says it does not declare Dag_before / Dag_after / dim inputs, and makes substrate-feasibility proof a prerequisite before implementation. If those inputs cannot be represented with existing .dag facts and fixtures, the worker must stop and escalate for substrate-extension authority. — sent from clever-tern-670

Root Cause

docs/briefs/r3-affected-set-introspect-lens-prototype-worker.md tests-as-data acceptance assumes the tests/dag directory is self-discovering, while live execution is still Rust-table-mediated → add a zero-SG-0 executable receipt requirement or make missing runner coverage a STOP condition.

⚠️ One dispatch-blocking gap remains: the worker needs an executable zero-SG-0 test path, not just checked-in fixture files.

…ting (#2719) * docs(audit): R3 deferral anti-pattern audit (PROPOSAL — Director-authored) Surfaces the broader anti-pattern class around cost-lens Miss dissolution (operator-ratified 2026-05-11). Grep-verified ~1600+ instances of deferral-via-wrapper-variant in v3 compiler production surface across 13 categories (Option<T>, panic!, .expect(), NotYetImplemented, DescentUnknown, ArrowBody::Pending, _ => catch-alls, etc.). Per operator-directive: "Miss should go away entirely; if something in substrate defines a Miss it should fail and be investigated asap" — extended to whole anti-pattern class. Each category dissolution path proposed. Tagged for PM (deep-wolf-155) + Mgr ratification: scope, sequencing, PR-template ratchet authoring authority. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * docs(audit): address openai-pro REQUEST_CHANGES — narrow Miss-class scope; reconcile DescentUnknown authority Per openai-pro review (#2708 c#4425020297, verdict REQUEST_CHANGES): 3 valid blocking findings addressed: 1. LAYER MODEL — §3.2 DescentEvidence::DescentUnknown removal conflated Miss-class deferral with fail-closed lattice bottom (INVARIANTS.md:63-66). Reframed: dissolution requires PM-tier ratification on (a) keep 3-variant lattice + construction-side narrowing OR (b) authority update first + 2-variant collapse. No worker dispatch until PM ratifies. 2. INVARIANTS + modeling-discipline — §1 row 1, §2.2 paragraph: "all 83 Option<T> = pure deferral" overgeneralized. Per modeling-discipline.md:41-50 + CODING.md:95-97, Option<T> is allowed when absence is meaningful. Reframed as triage candidates with per-site classification (error-None = Miss-class; legitimate-absence = compliant); explicit "don't bulk-convert." 3. CODING.md — §4 review checklist phrased as "flag for conversion" which conflicts with CODING.md:307-309 (Option/Result OK when meaningful). Reframed as "flag for justification": reviewer asks, author justifies; non-compliant cases convert, compliant wrappers survive. §0 framing also clarified: Miss-class deferral ≠ all Option<T>; per-site classification required; bulk-conversion would itself be a discipline violation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address codex REQUEST_CHANGES — eliminate internal authority contradictions Per codex review (#2708 c#4425182*, verdict REQUEST_CHANGES): 2 valid blocking findings addressed: 1. §1 table — rows 2-7 stated definitive violations ("should be typed Diagnostics", "admits non-exhaustiveness", "explicit 'I haven't decided this'") while §2.2 later correctly narrowed these to per-site triage. Two conflicting authorities within the same brief violated INVARIANTS P2 single-authority discipline. Fix: table notes now reflect the triage framing (boundary tooling vs interior substrate flow per CODING.md 307-309; closed-enum vs deliberate-default catch-alls; etc.). Rows 9-13 tagged with explicit cross-references to §3 disposition. 2. §5 sequencing — proposed §3.2 (DescentUnknown) same-batch dispatch with §3.1, but §3.2 itself blocked dispatch on PM ratification of path (a) vs (b). Fix: §5 now explicitly marks §3.2 + §3.6 as PM-blocked authority gates; only path (a) ratification would enable same-batch with §3.1; path (b) requires INVARIANTS.md edit landing first. Authority-gate summary appended. Also relabeled §2.1 "Pure deferral" → "Miss-class deferral" and removed DescentUnknown from the auto-classified list (consistent with §3.2 gate). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address inline blocking — reconcile §3.3 DescentResidual with Director-ratified γ-shape Per inline review finding at docs/audit/r3-deferral-anti-pattern-audit-2026-05-11.md:101 (2026-05-11T21:03:41Z): > "BLOCKING: §3.3 reclassifies the Director-ratified terminal DescentResidual > as Miss-shape without reconciling the current termination.dag authority, > which violates P1 modeling faithfulness and locked-decision discipline." Valid finding. The `DescentResidual = EvidenceUnknown(NonStrictEvidence) | EvidenceIncomplete` shape was Director-ratified via the illegal-states-unrepresentable rationale in docs/briefs/r3-substrate-descent-execution-proof-worker.md (gunbc#828 issuecomment-4395060514). The audit incorrectly conflated the analyzer's runtime-failure surface with a Miss-class design-laziness deferral. Same pattern as the prior §3.2 DescentUnknown correction (openai-pro REQUEST_CHANGES): - §3.3 reframed: no direct dissolution proposed; instead, pre-dispatch requirement to read existing authority + produce grep-verified reason + PM ratification. - §1 table row 11: tagged "authority-conflicting per Director-ratified γ-shape — compliant as written today." - §2.1: removed residual from Miss-class auto-classified list; appended to the "NOT auto-classified" entries alongside DescentUnknown. - §5 sequencing: §3.3 now authority-blocked (same as §3.2 + §3.6); cannot same-batch with §3.1 until reconciliation lands. Authority-gate footer updated. Pattern: every authority-conflicting dissolution proposal must (a) start from grep-verified read of existing authority, (b) name the specific authority doc affected, (c) require PM ratification before dispatch. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address inline blocking — §3.6 ArrowBody location was factually wrong Per inline review finding at docs/audit/r3-deferral-anti-pattern-audit-2026-05-11.md:120 (2026-05-11T21:03:41Z): > "BLOCKING: ArrowBody::Pending is stored on TypeConnective::Arrow.body/ > ResolvedArrow, not Behavior::Transform.body, so §3.6 aims the redesign > at the wrong substrate boundary under P2 facts-flow-forward." Verified at HEAD: - ArrowBody enum at src/v3/compiler/src/dag.rs:1092 - Used in TypeConnective::Arrow { body, .. } patterns (bootstrap.rs:288 etc.) - All ArrowBody::Unparsed sites in bootstrap_generated.rs are inside TypeConnective::Arrow { body: ArrowBody::Unparsed(...), .. } Original §3.6 claim that ArrowBody is on Behavior::Transform.body was wrong. Actual location is declaration-tier type-connective (Declaration.connective = TypeConnective::Arrow { body: ArrowBody::Pending }). Fix: §3.6 reframed. The substrate-shape question is at the declaration-tier type-connective layer, NOT Behavior::Transform. The "paper-over" cost is at the type-connective-walking layer; Behavior walkers already see only resolved bodies. Revised proposal: PM ratification on R3-load-bearing-ness + Substrate Mgr canvas on partition-vs-sum-with-Pending design question, citing M1_DESIGN.md authority + per-walker impact analysis. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address inline blocking — LensSurfacePending is terminal, not in-progress Per inline review finding at docs/audit/r3-deferral-anti-pattern-audit-2026-05-11.md:37 (2026-05-11T21:03:41Z): > "BLOCKING: LensSurfacePending is a terminal ParallelismUnsupportedKind in > the effects substrate, not an in-progress substrate state, so grouping it > with ArrowBody::Pending needs explicit authority reconciliation before > dispatch under P1 modeling faithfulness." Verified at HEAD: src/v3/compiler/src/dag/effects.rs:197 places LensSurfacePending as a variant of ParallelismUnsupportedKind, explicitly marked 🟢 TERMINAL in code comments. It's an explicit unsupported-reason payload for the parallelism lens, NOT a transitional in-progress state. The "Pending" suffix is misleading. Fix: removed LensSurfacePending from §3.6 (which only covers true pre-lowering transitional state ArrowBody::Pending). Updated §1 table row 12 + §2.1 Miss-class list to explicitly NOT auto-classify it. Removed scope contradiction. Pattern continues from prior corrections: every classification in the audit needs grep-verified factual grounding. Misleading variant names ("Pending" suffix on terminal carriers) are themselves a discipline gap. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address cursor NON-BLOCKING table nits — rows #10/#11 misattributed conflict Per cursor APPROVE_WITH_COMMENTS review at sha 0c07f7a (2026-05-11T21:08:35Z): > Row 10/11 phrase 'Authority-conflicting per X' but the cited authority X is > exactly where the standing design is *defined*. The real tension is between > the operator's Miss-elimination directive and that existing authority text, > not 'conflict' within or stated by those authorities themselves. Fix: reframe rows #10/#11 to name the standing authority + locate the tension correctly: - Row 10 (DescentUnknown): standing authority is INVARIANTS.md fail-closed bottom; tension is with operator directive (not within the invariant). - Row 11 (DescentResidual): standing authority is Director-ratified γ-shape; carrier is compliant; my prior audit framing was the conflict, corrected in §3.3. NON-BLOCKING per reviewer but legitimate clarity improvement; reviewer's verdict was APPROVE_WITH_COMMENTS. * docs(audit): tighten CODING.md citations — boundary roles at :311-321, not :307-309 Per cursor APPROVE_WITH_COMMENTS finding at sha 0af402f (2026-05-11T21:24:39Z): > The notes point boundary-tooling legitimacy at CODING.md:307-309, but those > lines only state the narrow 'Hidden panic surface' rule (library avoids > contract-violation panics/unwrap()). The explicit Bootstrap and > Code-generation binaries edge roles appear under 'When impurity is > acceptable' beginning around CODING.md:311 (table ~317-321). Fix: split the citation so: - CODING.md:307-309 covers the contract-violation-in-library rule (interior substrate-flow panics dissolve to typed Diagnostic per C-8). - CODING.md:311-321 covers the boundary roles legitimacy (Build script / Code-generation binaries / Bootstrap entries in the impurity-acceptable table). Updated table rows #2/#3 (lines 27-28), §2.2 prose (line 66), and §4 review checklist (line 171). NON-BLOCKING per reviewer; landing as documentation hygiene. * docs(audit): add §3.8.1 concrete 10-entry NON_TEST inventory per velocity-walk Per PM ratification (msg_45457c77 in response to Director ask msg_048fdfa6): empirical-grounding-strengthens-the-case path. §3.8 currently treats structural_coverage_gap audit as abstract pattern; with zesty-boar-261's velocity-walk diagnostic (gunbc#846 c#4425420798) producing a 9 NON_TEST + 1 FRAGMENTS enumerated inventory over the 7d window pre-2026-05-11, §3.8 graduates from speculative to grounded. Adds §3.8.1 with: - 10-entry table: file path + LOC + adjacent-lane/dissolution-path mapping - Total 2,171 LOC; omni_shape_b_openapi.rs identified as ~40% of class - Audit implication: per-file promote-or-carve discipline applies - Per-PR review state-space framing (Director conformance read flags absent dissolution-path mapping) - Re-audit cadence note (this is window-relative intro composition, not full main §3.8 audit; per feedback_intro_rate_not_residual_share) Citations grep-verified at HEAD eed86ff: all 9 NON_TEST files exist with stated LOC; FRAGMENTS entry confirmed in sg0_census_test.rs:688-691. * docs(briefs): Director scaffold-fill for Cluster M Phase 3 reflected-Dag + DimensionReport bulk-port worker briefs Per feedback_pre_authored_brief_queue + feedback_director_mgr_energy_input (Director energy INTO system until real workflow substrate exists). Verification Mgr (clever-tern-670) status pass (msg_755c3f43) identified Phase 3 dissolution-rate bottleneck as Mgr-tier brief-authoring bandwidth on the two biggest unauthored classes: - Reflected-Dag structural assertion family (~25-30 entries; 16 seed-named) - Generic DimensionReport / runner-discipline family (~20-25 entries; 10 seed-named) These ~50 entries combined are roughly half of the #84 EXPECTED_HAND_AUTHORED_TEST partition (116 entries on origin/main eed86ff). Authoring scaffolds + Mgr finalization + dispatch should land bulk-port PRs within 7-10 days, with velocity-tripwire arrow (12.7:1 intros:dissolves at gunbc#846 c#4425420798) flipping intra-week. Authority split per Director msg_eb2372c7 to PM: - Director: scaffold shape (this commit) — locked-design citations, substrate carrier references at exact lines, Phase-2 pattern site refs, hard constraints, STOP-and-escalate criteria, decomposition recommendations. - Verification Mgr: finalization — complete inventory (Mgr-fill placeholders marked throughout), per-entry classification, pilot selection, dispatch. Substrate citations grep-verified via Verification Mgr msg_755c3f43: - ProgramGenerator/ProgramShape/Quantifier/QuantifiedTestClaim/SuiteClaim: src/v3/std/verification.dag:118-133 + :379-402 (carriers landed) - TestSuite.claims still List<TestClaim>: verification.dag:404-407 (staged trigger at :394-399) — Reflected-Dag class CONSUMER-GATED on this flip - Phase-2 pattern: t_pb_b_1_dag_runner_test.rs:257-357 (R3_GATE_87_CEMENTING_REGEN_SUITES, run_suite_all_pass_with_expected_claim_names) - Receipt discipline: r3_gate_87_lens_cementing_regen_receipts_test.rs:13-24 + :122-132 - DimensionReport class NOT consumer-gated (Phase-2 pattern is the load-bearing predicate, not full #87 PASSING, per feedback_construction_over_ratchets) * docs(briefs): Director scaffold-fill for R3 CI Layer 2 path-conditional gating Per PM ratification at gunbc#828 c4425726922 + Director ratification msg_a77c7f42 (Verification Mgr routing per feedback_parallel_representation_debt coherence). Bridge-debt with named dissolution trigger: when gate ci_uses_provable_minimal_affected_set_selection lands, the affected-set Introspect-lens output (canvas PR #2713) replaces the bridge's required_paths_regex column. Brief covers: - §0 scope: extend PR #2718's changes job, do not parallel - §1 mechanism: per-group skip_* boolean outputs + STEP-level if: on v3 - §2 inventory sources (slow-test-exemptions.txt + /tmp/v3-test-timings.log + NEW per-group required-paths mapping) - §3 per-dimension structural target — every entry has dimension: Dimension field matching lens enum (parallel-representation-debt prevention) - §4 hard constraints (8 invariants) - §5 acceptance - §6 decomposition (Mgr-fill recommendation: cost_lens pilot first) - §7 STOP-and-escalate criteria - §8 bridge-debt + dissolution path explicit Verification Mgr (clever-tern-670) fills inventory + per-group regex + dispatch. Director scaffold preserves coherence; Mgr finalizes per feedback_director_mgr_energy_input. * docs(briefs): fix Layer 2 YAML naming inconsistency (skip_cost → skip_cost_lens) Per cursor APPROVE_WITH_COMMENTS at sha 04c5b08 (review 9701): > The changes outputs define skip_cost, but the v3 step's if: uses > needs.changes.outputs.skip_cost_lens. That disagrees with the same brief's > post-dissolution sketch (skip_$group with cost_lens → skip_cost_lens, lines > 129-134). Not a formal invariant breach by itself, but it is easy for an > implementer to copy the wrong name and get an always-on/off step. Fix: normalize the example YAML outputs block to match the if: lines and the post-dissolution sketch. Naming convention: skip_<group_name> where <group_name> matches the per-group table's group_name column verbatim (no abbreviation). Updated all 4 example outputs: skip_lens → skip_complexity_lens (was vague; tied to specific group) skip_emit → skip_emit_target (matches starting template at §2) skip_parser → skip_parser_grammar (matches starting template) skip_cost → skip_cost_lens (matches if: line + post-dissolution sketch) Also added an inline comment documenting the naming convention so future copy-paste from the example stays mechanically correct. * docs(briefs): cite PM pre-staged Mgr-fill template (PR #2721) + converge pilot recommendation on Cluster B Per PM msg_bba47649 — pre-staged Mgr-fill template landed as PR #2721 (docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md, 220 lines). Two scaffold updates: 1. §2 (inventory sources): replaced 'PM pre-staged skeleton to be attached if/when available' speculative reference with explicit cite-and-link to the landed template doc. Describes what the PM template provides: - All 78 slow-test-exemptions.txt entries grouped into 9 clusters (A-I) - (test_pattern, dimension, required_paths_regex) skeleton table - 12 [Mgr-fill] placeholders for substrate-lens / R3-V L4/L7 / R1C-E / free-consequences cross-target tracing 2. §6 (decomposition): converged my prior cost_lens-first pilot recommendation with PM's Cluster B recommendation — these are the same family (Lane 2 Stage 2d symbolic cost = cost-lens). Updated wording to reflect Cluster naming + cross-citation to PM template's Cluster B detail. Added [Mgr-fill] placeholder resolution wave to decomposition. Inline sketch table retained as illustrative; defer to PM template for actual starting inventory. * WIP: gunbc Director * docs(briefs): fix singular dimension → Set<Dimension> per PM caught semantic violation PM (msg_ab551c52) surfaced codex RC on template PR #2721 (review #9707): singular 'dimension:' field violates locked-design §2 union semantics. A multi-dim consumer (e.g., LBP demonstration reading both complexity + cost) declared with singular dimension: cost would be silently skipped when only complexity changes — fail-open violation against P3. PM fixed their template at dedcf69: dimension → dimensions (Set<Dimension>), union-formula clarified, multi-dim rows expanded. This brief had the same singular semantics; absorbed the fix per PM recommendation so Verification Mgr inherits coherent dim-set semantic across both authority chain artifacts (brief + template). Changes: - §0 authority bullet: contains(single) → (∩ ≠ ∅) intersection-non-empty; dimension: Dimension → dimensions: Set<Dimension> - §2 table column rename + type spec + union semantics note + multi-dim consumer guidance - §2 starting template citation updated to reflect post-fix template at dedcf69 - §3 section header renamed; substantive paragraph explaining WHY Set<Dimension> not Dimension (cites PM caught violation + P3 fail-open framing) - §3 YAML example: jq script updated to set-intersection check - §4.5 hard constraint: dimensions: Set<Dimension> with members from enum; empty set invalid - §5 acceptance: every group has dimensions: Set<Dimension>; multi-dim fidelity language - §6 pilot description: 'singleton {cost} dimensions' phrasing; class wave reviewer-check language updated - §7 STOP: added multi-dim escalation path; explicit warning against defaulting to singleton {primary} - §8 surviving artifact: (group_name, dimensions) — set-typed column survives - inline illustrative table: explicit set-literal notation with multi-dim row example (lbp_demonstration: {complexity, cost}) Same authority chain absorbs cleanly: brief (primary) + template (data attachment) now both set-typed; Verification Mgr inherits coherent semantic. * docs(briefs): fix boolean polarity inversion + add polarity invariant per openai-pro RC on template PM (msg_9a188e22) surfaced openai-pro BLOCKING re-review (#9721) on template PR #2721 at 93080af — caught load-bearing boolean polarity inversion: brief stated skip_* formula as (affected ∩ row.dimensions) ≠ ∅ (skip when intersection NON-empty) while CI consumer wires if: skip != 'true' (run when skip is false). Net effect: literal-following Mgr/worker would wire the gate to silently skip AFFECTED tests when intersection is non-empty. TESTING.md + Boundary Discipline violation. PM fixed template at 262f42d (4 sites inverted; explicit polarity table added at §1/§3/§4/§5). Same risk on this brief (#2719) at the post-dissolution mapping site I authored when absorbing the prior dim-set fix at efacecd. Fix: §0 authority bullet (line 10, the inversion site): before: 'skip_* flags become (∩ ≠ ∅)' [INVERTED — fail-open] after: 'skip_* flags become skip_<group> = (∩ = ∅)' [canonical] + explicit polarity check note + carrier-vs-contract explanation + skip-form / run-form equivalence stated §3 substantive paragraph (after Set<Dimension> WHY): added Polarity invariant block citing PM's caught inversion + 262f42d fix + explicit warning that skip = (∩ ≠ ∅) is the canonical fail-open boolean-polarity bug pattern. §4 hard constraint #5 (dimensions field): added inline Polarity invariant restating the canonical skip-form + run-form equivalent + 'never invert' clause. §5 acceptance: added 'Polarity check passes' criterion enumerating the acceptable forms + naming the inverted form as the fail-open pattern to reject in review. Self-test text clarified: cost-dimension groups run, other-dimension groups skip (verifies correct polarity in actual gate). YAML example at §3 (lines 139-149) was already polarity-correct (skip iff intersection empty; skip=true when intersection empty) so unchanged. Single-pass absorption per PM recommendation — both brief and template now lockstep on polarity semantics. Verification Mgr inherits both files without polarity mismatch in finalization. * WIP: gunbc Director * docs(briefs): align §0 example names with §1 naming convention (cursor exploratory) Per cursor APPROVE exploratory observation on PR #2719 sha 13b0db9 (review #9732): §0 line 25 illustrative outputs used abbreviated names (skip_lens / skip_emit / skip_parser) while §1 line 53-54 establishes strict 'skip_<group_name>' naming convention matching the per-group table verbatim. Non-policy violation per cursor but tightening avoids ambiguity for implementer. Fix: replace abbreviated names with full-form (skip_cost_lens / skip_emit_target / skip_parser_grammar) + cross-reference §1 naming convention in the same sentence. Brief now consistent across all naming sites. * docs(briefs): add P3 fail-closed shared-infrastructure full-run bucket per codex BLOCKING codex REQUEST_CHANGES on PR #2719 at sha 52c6cf0 (review #9744): Line 102 narrowed required-paths inventory to 'src/v3/*' deps only; the illustrative table at lines 114-118 followed that shape. A PR that changes shared test infrastructure or selection machinery outside src/v3/* (.github/workflows/ci.yml, scripts/*, Cargo.lock, rust-toolchain.toml, etc.) would be classified as 'unaffected' for every per-group regex and silently skip tests whose behavior actually changed. That's the fail-open boundary class P3 forbids + TESTING.md behavior-driven discipline violation. Real correctness issue in the proposed mechanism, not just an implementation detail. Fix: add shared-infrastructure full-run fail-closed bucket as the join-point that catches inter-group / cross-cutting changes: §2 (inventory sources): added 'Shared-infrastructure full-run fail-closed bucket' subsection with explicit mechanism — changes job computes force_full_run = (any changed file matches shared-infra regex); when true, all per-group skip_* short-circuit to false. Regex spec: ^(\.github/.*|scripts/.*|Cargo\.(toml|lock)|rust-toolchain\.toml| \.cargo/.*|build\.rs)$. Names the structural rationale: per-group regexes cover ONLY their own src/v3/* deps; the full-run trigger is the join-point. Fail-closed by construction. §4 hard constraint #9 (new): formalizes the invariant + 'never collapse the full-run trigger into per-group regexes' (structural fail-open shape). §5 acceptance: added 'Shared-infrastructure full-run check passes' as separate criterion + self-test case (c) — a PR touching only .github/workflows/ci.yml or Cargo.lock or scripts/check-test-timeout.sh MUST run all test groups. Expanded self-test from 3 to 4 cases (a/b/c/d). §2 added [Mgr-fill]: validate shared-infra regex against representative recent PRs. Single-pass absorption; brief now P3 fail-closed at the cross-cutting boundary. * WIP: gunbc Director * docs(briefs): fix two openai-pro BLOCKINGs — harness-arm in shared-infra regex + cargo test substring not glob openai-pro REQUEST_CHANGES on PR #2719 at sha 0d3b44b (review #9749 + manual c4426188322): BLOCKING #1 (P3 Fail-Closed): brief at line 104 names 'harness code' as a class to catch in full-run regex but the actual regex at line 109 had no harness/test-selection arm. Harness-only changes (e.g., to tests/integration/common/* or sg0_census_test.rs) would miss both full-run regex AND per-group regexes — silent skip. BLOCKING #2 (TESTING.md fail-closed CI): test_pattern field documented as 'cargo test arg pattern' but examples used glob-looking syntax (cost_lens_*, *_emit_*). Cargo positional test arg is a libtest SUBSTRING filter, not a glob. Worker following the brief literally would produce a step that runs zero intended tests + exits successfully — silent skip converting 'selected group tested' into 'selected group filtered out.' Fixes: #1 (harness arm in shared-infra regex): - §2 mechanism: extended regex to include src/v3/compiler/tests/integration/common/.*, sg0_census_test.rs, test_runner_test.rs, t_pb_b_1_dag_runner_test.rs, integration.rs, integration test entry points - §2 new paragraph naming the harness/test-selection-machinery arms explicitly + hard rule: harness-class files MUST never appear in a per-group required_paths_regex - §4 hard constraint #9: extended invariant to include harness class with explicit file list - §5 acceptance: extended self-test case (c) to include harness-class example (common/cached_compile.rs) + explicit verification list #2 (cargo test substring, not glob): - §1 YAML examples: cost_lens_* → cost_lens; *_emit_* → emit; added IMPORTANT comment explaining libtest substring semantics + forbidding glob syntax - §2 test_pattern column spec: re-documented as 'libtest test-name SUBSTRING filter (NOT a glob)' with cost_lens example + glob forbiddance + --exact alternative - §2 inline illustrative table: cost_lens_* → cost_lens (and others); added trailing comment naming substring semantics - §4 new hard constraint #10: test_pattern is substring filter not glob; self-test that the value substitutes verbatim into cargo test and runs positive number of tests - §5 acceptance: new 'test_pattern substring-filter check passes' criterion with empirical pilot-wave validation requirement Brief now P3 fail-closed at both the boundary (shared-infra full-run including harness) AND the selector (substring filter that workers can copy verbatim without silent zero-test execution). Single-absorption pass; awaiting fresh review at new HEAD. * docs(briefs): reframe PM template citation per codex P1/P2 — template is on PR #2721, NOT yet landed on main codex REQUEST_CHANGES on PR #2719 (review #9754): Line 128 named docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md as a 'landed' starting authority, but git ls-tree origin/main returns no blob and git ls-files returns nothing. A worker following this brief would be sent to a non-existent source of truth — INVARIANTS P1/P2 authority-grounding violation in a dispatch document. Verified at HEAD: - git ls-tree origin/main -- docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md → empty - gh pr view 2721 → state=OPEN, mergedAt=null - Template lives on PR #2721's branch only Fix: reframe the template citation to acknowledge PR #2721 is open-not-landed. - 'landed via PR #2721' → 'open as PR #2721 ... NOT yet landed on main' - Added codex BLOCKING citation + verification receipt (git ls-tree result) - Added explicit authority caveat: Verification Mgr finalization MUST coordinate merge sequencing — (a) merge #2721 first, OR (b) read from PR #2721 branch until it merges - Named PM (deep-wolf-155) as PR #2721 author + cross-link for merge coordination - Cited sha 262f42d (PR #2721 post-fix state per PM msg_125e3aa5) Brief now accurately grounded on the actual file location (PR #2721 branch) with merge-sequencing guidance for Mgr finalization. Authority chain honest about in-flight vs landed state. * WIP: gunbc Director * docs(briefs): absorb 3 BLOCKING findings (Brian + codex) — R4 lifecycle reframe + canonical 2-step + count fix Brian inline BLOCKING #1 + codex BLOCKING #1 (P5 dissolution-trigger authority): brief framed dissolution as R3 close-blocking gate 'ci_uses_provable_minimal_affected_set_selection' but docs/design-affected-set-lens.md:3 = 'R4 wishlist', :354 = 'CI integration sketch (deferred to R4 full delivery)', :366 = 'CI integration is R4 full-delivery work'. No ROADMAP authority exists for the cited gate name — that was Director-tier speculation. Brian inline BLOCKING #2 + codex BLOCKING #2 (Facts Flow Forward / surviving schema): §3 post-dissolution sketch only encoded dimension intersection, silently dropping NodeRef intersection. Canonical 2-step per design §5:359 requires BOTH (TestClaim.refs ∩ affected_nodes) ≠ ∅ AND (TestClaim.dims ∩ changed.dims) ≠ ∅. Reducing surviving schema to (group_name, dimensions) too early. codex non-blocking: slow-test-exemptions.txt count cited as 78 (PM template value); actual is 80 at 2026-05-12T00:50Z (verified locally: grep -v '^#' ... | grep -v '^$' | wc -l = 80). Fixes (single absorption pass): §0 'Bridge-debt → dissolution lifecycle' bullet: - Reframed from 'R3 close-blocking gate' to 'R4-bounded dissolution lifecycle (NOT R3 close)' with explicit citation of design doc :3 + :354 + :366. Names R4.B as R4 owner. Removes the speculative gate name. Names Brian's BLOCKING #1 absorption. §0 NEW 'Post-dissolution selection semantics (canonical 2-step join)' bullet: explicit NodeRef + dimension joins per design :359; run formula; skip formula; bridge coarseness acknowledgment (path-regex over-approximates canonical lens; fail-closed-safe but coarser). Names Brian's BLOCKING #2 absorption. §0 polarity check bullet: updated skip-form to reflect 2-step (NodeRef-empty OR dim-empty ⇒ unaffected ⇒ skip). §2 inventory source (a): count 78 → 80 at 3 sites (replace_all), with explanation that count grows over time + Mgr re-runs grep at finalization rather than relying on stale citations. §2 table column spec: added 'testclaim_references' as 5th column. Cited Brian's BLOCKING #2; explains bridge-tier proxy vs post-dissolution proxy. §2 [Mgr-fill]: extended to require testclaim_references computation per canonical 2-step. §3 YAML post-dissolution sketch: rewrote classify step to compose BOTH NodeRef AND dimension intersections via jq + cite Brian's BLOCKING #2 absorption inline. Header comment names R4.B authority and acknowledges no current ROADMAP gate ID. §4 #4 PR-body bridge-debt template: reworded from 'R3 close-blocking gate' to 'R4.B Introspect-lens saturation lane CI integration delivery; NOT R3 close-blocking.' §8 surviving artifact: corrected from (group_name, dimensions) to (group_name, dimensions, testclaim_references) per canonical; cited Brian's BLOCKING #2. Removed all references to 'ci_uses_provable_minimal_affected_set_selection' as a current ROADMAP gate name; replaced with R4.B owning-lane references + explicit acknowledgment of authority gap. Brief now P5-honest: dissolution trigger is checkable (R4.B owning lane) even if no concrete gate ID yet; surviving schema preserves both lens join inputs per canonical algorithm. * docs(briefs): reconcile §3 substantive + §7 STOP with §0/§8 — surviving schema is 3-column (cursor internal-consistency catch) cursor REQUEST_CHANGES on PR #2719 sha 540113f (review #9767): Two internal contradictions surfaced from my partial absorption of Brian's BLOCKING #2: (a) §3 substantive paragraph still said '(group_name, dimensions) mapping survives the dissolution — only required_paths_regex column gets retired' contradicting §0 + §8 which were updated to 3-column (group_name, dimensions, testclaim_references). (b) §7 STOP bullet referenced 'Layer 2 dissolution shape doesn't match (group_name, dimensions) schema' — 2-column framing, same contradiction. Fix: §3 substantive paragraph (around the parallel-representation-debt rationale): - 2-column → 3-column framing - both dimensions AND testclaim_references must be authored - cite design §:359 canonical 2-step join - cite cursor internal-consistency catch alongside Brian's BLOCKING #2 §7 STOP escalation bullet: - (group_name, dimensions) → (group_name, dimensions, testclaim_references) + cite canonical 2-step join Verified via grep: all remaining references are within meta-statements explicitly documenting the removal (line 10 + line 268); no live references remain. All appearances are either in updated 3-column contexts or in meta-statements referencing the absorption (line 15 catch citation). Brief now internally coherent across §0, §3, §7, §8 on: - dissolution trigger (R4.B owning lane, NOT removed-gate-name) - surviving schema (3 columns including testclaim_references) - canonical 2-step join semantics * docs(briefs): fix stale 78 inventory references at §2 lines 114 + 141 per openai-pro BLOCKING openai-pro REQUEST_CHANGES on PR #2719 sha 8ae7938 (review #9779): Brief had stale '78 active >2s entries' at line 114 + 'All 78 ... entries' at line 141, despite §0 line 19 + §2 line 157 stating live count is 80 and Mgr should re-run count at finalization. A worker following §2 literally could build the gating table from stale 78-entry basis, omitting 2 slow-test entries — fail-open shape against the brief's own P3 fail-closed contract (under-inventory = exemption falls in neither per-group regex nor full-run bucket = silently skipped). Fix: §2 inventory source (a) (line 114): replaced 'start with the 78 active >2s entries' with 'start with the current live count of active >2s entries (Mgr MUST re-run grep ... | wc -l at finalization; 80 at 2026-05-12T00:50Z but count grows; do NOT cite the stale 78 from PM template PR #2721 or any earlier reference)'. Added 'fail-closed completeness invariant' inline: every active exemption MUST appear in either a per-group required_paths_regex OR the harness/shared-infra full-run bucket; no exemption left unclassified. §2 PM template description (line 141): 'All 78 entries' → 'PM-grouped entries (PM template snapshot was 78 at template authoring time; live count grows — Mgr re-verifies via wc -l at finalization, NOT this stale historical reference)'. Added note that the 9-cluster taxonomy survives count growth; Mgr maps new entries to existing clusters or escalates if a new cluster surface emerges. Brief is now internally consistent on inventory-count freshness: - §0 line 19: live 80 with verification command - §2 line 114: re-run command at finalization; explicit do-not-cite-78 instruction - §2 line 141: PM template snapshot historical; live count grows - §2 line 157 (Mgr-fill): re-run grep, don't trust stale citations 12th distinct review-class catch this polish cycle: inventory-citation freshness as fail-closed completeness invariant. * docs(briefs): §5 acceptance requires testclaim_references explicitly per codex BLOCKING #9780 codex REQUEST_CHANGES on PR #2719 sha 8ae7938 (review #9780): Finding #1 (stale 78 at lines 114 + 141) already fixed at prior commit 487d175; codex finding overlaps with openai-pro #9779 absorbed before.

Fix: §5 acceptance adds new explicit criterion: 'Every group entry has testclaim_references: Set<NodeRef> field' with explicit citation chain (design §:359 + Brian BLOCKING #2 + codex BLOCKING #9780). Includes bridge-tier-proxy vs post-dissolution-proxy note. Includes 'Dimensions-only acceptance closeout is rejected: P2 facts-flow-forward requires both lens-join inputs.' §5 acceptance now coherent with §0/§3/§8 on the 3-column surviving schema; no path to 'done' that skips testclaim_references. 13th distinct review-class catch this polish cycle: acceptance-vs-substantive-text divergence on load-bearing fields. * docs(briefs): fix polarity-bullet dimensions-only residuals per cursor catch on #2725 review cursor APPROVE_WITH_COMMENTS on PR #2725 (review #9799) but finding applies to PR #2719's brief — lines 208 + 217 Polarity invariant bullets restated post-dissolution skip/run formula via dimensions-only, conflicting with the canonical 2-step join correctly stated at §3 substantive paragraph (line 200) + §3 YAML sketch (line 178-188) + §5 acceptance (line 231-232).

Verified this tests/dag runner finding against current head 19c1010. It is already addressed in the brief: §1 item 7 states tests/dag is not self-discovering and requires naming an existing TestRunner/suite path or STOP; §4 item 7 forbids a new Rust runner bridge; §5 requires a zero-SG-0 executable receipt with command/result; §6 stops if fixtures cannot execute through an existing runner path.

* docs(audit): R3 deferral anti-pattern audit (PROPOSAL — Director-authored) Surfaces the broader anti-pattern class around cost-lens Miss dissolution (operator-ratified 2026-05-11). Grep-verified ~1600+ instances of deferral-via-wrapper-variant in v3 compiler production surface across 13 categories (Option<T>, panic!, .expect(), NotYetImplemented, DescentUnknown, ArrowBody::Pending, _ => catch-alls, etc.). Per operator-directive: "Miss should go away entirely; if something in substrate defines a Miss it should fail and be investigated asap" — extended to whole anti-pattern class. Each category dissolution path proposed.

LAYER MODEL — §3.2 DescentEvidence::DescentUnknown removal conflated Miss-class deferral with fail-closed lattice bottom (INVARIANTS.md:63-66). Reframed: dissolution requires PM-tier ratification on (a) keep 3-variant lattice + construction-side narrowing OR (b) authority update first + 2-variant collapse. No worker dispatch until PM ratifies. 2. INVARIANTS + modeling-discipline — §1 row 1, §2.2 paragraph: "all 83 Option<T> = pure deferral" overgeneralized. Per modeling-discipline.md:41-50 + CODING.md:95-97, Option<T> is allowed when absence is meaningful. Reframed as triage candidates with per-site classification (error-None = Miss-class; legitimate-absence = compliant); explicit "don't bulk-convert." 3. CODING.md — §4 review checklist phrased as "flag for conversion" which conflicts with CODING.md:307-309 (Option/Result OK when meaningful). Reframed as "flag for justification": reviewer asks, author justifies; non-compliant cases convert, compliant wrappers survive. §0 framing also clarified: Miss-class deferral ≠ all Option<T>; per-site classification required; bulk-conversion would itself be a discipline violation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address codex REQUEST_CHANGES — eliminate internal authority contradictions Per codex review (#2708 c#4425182*, verdict REQUEST_CHANGES): 2 valid blocking findings addressed: 1. §1 table — rows 2-7 stated definitive violations ("should be typed Diagnostics", "admits non-exhaustiveness", "explicit 'I haven't decided this'") while §2.2 later correctly narrowed these to per-site triage. Two conflicting authorities within the same brief violated INVARIANTS P2 single-authority discipline. Fix: table notes now reflect the triage framing (boundary tooling vs interior substrate flow per CODING.md 307-309; closed-enum vs deliberate-default catch-alls; etc.). Rows 9-13 tagged with explicit cross-references to §3 disposition. 2. §5 sequencing — proposed §3.2 (DescentUnknown) same-batch dispatch with §3.1, but §3.2 itself blocked dispatch on PM ratification of path (a) vs (b). Fix: §5 now explicitly marks §3.2 + §3.6 as PM-blocked authority gates; only path (a) ratification would enable same-batch with §3.1; path (b) requires INVARIANTS.md edit landing first. Authority-gate summary appended. Also relabeled §2.1 "Pure deferral" → "Miss-class deferral" and removed DescentUnknown from the auto-classified list (consistent with §3.2 gate). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address inline blocking — reconcile §3.3 DescentResidual with Director-ratified γ-shape Per inline review finding at docs/audit/r3-deferral-anti-pattern-audit-2026-05-11.md:101 (2026-05-11T21:03:41Z): > "BLOCKING: §3.3 reclassifies the Director-ratified terminal DescentResidual > as Miss-shape without reconciling the current termination.dag authority, > which violates P1 modeling faithfulness and locked-decision discipline." Valid finding. The `DescentResidual = EvidenceUnknown(NonStrictEvidence) | EvidenceIncomplete` shape was Director-ratified via the illegal-states-unrepresentable rationale in docs/briefs/r3-substrate-descent-execution-proof-worker.md (gunbc#828 issuecomment-4395060514). The audit incorrectly conflated the analyzer's runtime-failure surface with a Miss-class design-laziness deferral. Same pattern as the prior §3.2 DescentUnknown correction (openai-pro REQUEST_CHANGES): - §3.3 reframed: no direct dissolution proposed; instead, pre-dispatch requirement to read existing authority + produce grep-verified reason + PM ratification. - §1 table row 11: tagged "authority-conflicting per Director-ratified γ-shape — compliant as written today." - §2.1: removed residual from Miss-class auto-classified list; appended to the "NOT auto-classified" entries alongside DescentUnknown. - §5 sequencing: §3.3 now authority-blocked (same as §3.2 + §3.6); cannot same-batch with §3.1 until reconciliation lands. Authority-gate footer updated. Pattern: every authority-conflicting dissolution proposal must (a) start from grep-verified read of existing authority, (b) name the specific authority doc affected, (c) require PM ratification before dispatch. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address inline blocking — §3.6 ArrowBody location was factually wrong Per inline review finding at docs/audit/r3-deferral-anti-pattern-audit-2026-05-11.md:120 (2026-05-11T21:03:41Z): > "BLOCKING: ArrowBody::Pending is stored on TypeConnective::Arrow.body/ > ResolvedArrow, not Behavior::Transform.body, so §3.6 aims the redesign > at the wrong substrate boundary under P2 facts-flow-forward."

Actual location is declaration-tier type-connective (Declaration.connective = TypeConnective::Arrow { body: ArrowBody::Pending }). Fix: §3.6 reframed. The substrate-shape question is at the declaration-tier type-connective layer, NOT Behavior::Transform.

It's an explicit unsupported-reason payload for the parallelism lens, NOT a transitional in-progress state. The "Pending" suffix is misleading.

Updated §1 table row 12 + §2.1 Miss-class list to explicitly NOT auto-classify it. Removed scope contradiction. Pattern continues from prior corrections: every classification in the audit needs grep-verified factual grounding. Misleading variant names ("Pending" suffix on terminal carriers) are themselves a discipline gap. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(audit): address cursor NON-BLOCKING table nits — rows #10/#11 misattributed conflict Per cursor APPROVE_WITH_COMMENTS review at sha 0c07f7a (2026-05-11T21:08:35Z): > Row 10/11 phrase 'Authority-conflicting per X' but the cited authority X is > exactly where the standing design is *defined*. The real tension is between > the operator's Miss-elimination directive and that existing authority text, > not 'conflict' within or stated by those authorities themselves. Fix: reframe rows #10/#11 to name the standing authority + locate the tension correctly: - Row 10 (DescentUnknown): standing authority is INVARIANTS.md fail-closed bottom; tension is with operator directive (not within the invariant). - Row 11 (DescentResidual): standing authority is Director-ratified γ-shape; carrier is compliant; my prior audit framing was the conflict, corrected in §3.3. NON-BLOCKING per reviewer but legitimate clarity improvement; reviewer's verdict was APPROVE_WITH_COMMENTS. * docs(audit): tighten CODING.md citations — boundary roles at :311-321, not :307-309 Per cursor APPROVE_WITH_COMMENTS finding at sha 0af402f (2026-05-11T21:24:39Z): > The notes point boundary-tooling legitimacy at CODING.md:307-309, but those > lines only state the narrow 'Hidden panic surface' rule (library avoids > contract-violation panics/unwrap()). The explicit Bootstrap and > Code-generation binaries edge roles appear under 'When impurity is > acceptable' beginning around CODING.md:311 (table ~317-321). Fix: split the citation so: - CODING.md:307-309 covers the contract-violation-in-library rule (interior substrate-flow panics dissolve to typed Diagnostic per C-8). - CODING.md:311-321 covers the boundary roles legitimacy (Build script / Code-generation binaries / Bootstrap entries in the impurity-acceptable table). Updated table rows #2/#3 (lines 27-28), §2.2 prose (line 66), and §4 review checklist (line 171). NON-BLOCKING per reviewer; landing as documentation hygiene. * docs(audit): add §3.8.1 concrete 10-entry NON_TEST inventory per velocity-walk Per PM ratification (msg_45457c77 in response to Director ask msg_048fdfa6): empirical-grounding-strengthens-the-case path. §3.8 currently treats structural_coverage_gap audit as abstract pattern; with zesty-boar-261's velocity-walk diagnostic (gunbc#846 c#4425420798) producing a 9 NON_TEST + 1 FRAGMENTS enumerated inventory over the 7d window pre-2026-05-11, §3.8 graduates from speculative to grounded. Adds §3.8.1 with: - 10-entry table: file path + LOC + adjacent-lane/dissolution-path mapping - Total 2,171 LOC; omni_shape_b_openapi.rs identified as ~40% of class - Audit implication: per-file promote-or-carve discipline applies - Per-PR review state-space framing (Director conformance read flags absent dissolution-path mapping) - Re-audit cadence note (this is window-relative intro composition, not full main §3.8 audit; per feedback_intro_rate_not_residual_share) Citations grep-verified at HEAD eed86ff: all 9 NON_TEST files exist with stated LOC; FRAGMENTS entry confirmed in sg0_census_test.rs:688-691. * docs(briefs): Director scaffold-fill for Cluster M Phase 3 reflected-Dag + DimensionReport bulk-port worker briefs Per feedback_pre_authored_brief_queue + feedback_director_mgr_energy_input (Director energy INTO system until real workflow substrate exists). Verification Mgr (clever-tern-670) status pass (msg_755c3f43) identified Phase 3 dissolution-rate bottleneck as Mgr-tier brief-authoring bandwidth on the two biggest unauthored classes: - Reflected-Dag structural assertion family (~25-30 entries; 16 seed-named) - Generic DimensionReport / runner-discipline family (~20-25 entries; 10 seed-named) These ~50 entries combined are roughly half of the #84 EXPECTED_HAND_AUTHORED_TEST partition (116 entries on origin/main eed86ff). Authoring scaffolds + Mgr finalization + dispatch should land bulk-port PRs within 7-10 days, with velocity-tripwire arrow (12.7:1 intros:dissolves at gunbc#846 c#4425420798) flipping intra-week. Authority split per Director msg_eb2372c7 to PM: - Director: scaffold shape (this commit) — locked-design citations, substrate carrier references at exact lines, Phase-2 pattern site refs, hard constraints, STOP-and-escalate criteria, decomposition recommendations. - Verification Mgr: finalization — complete inventory (Mgr-fill placeholders marked throughout), per-entry classification, pilot selection, dispatch. Substrate citations grep-verified via Verification Mgr msg_755c3f43: - ProgramGenerator/ProgramShape/Quantifier/QuantifiedTestClaim/SuiteClaim: src/v3/std/verification.dag:118-133 + :379-402 (carriers landed) - TestSuite.claims still List<TestClaim>: verification.dag:404-407 (staged trigger at :394-399) — Reflected-Dag class CONSUMER-GATED on this flip - Phase-2 pattern: t_pb_b_1_dag_runner_test.rs:257-357 (R3_GATE_87_CEMENTING_REGEN_SUITES, run_suite_all_pass_with_expected_claim_names) - Receipt discipline: r3_gate_87_lens_cementing_regen_receipts_test.rs:13-24 + :122-132 - DimensionReport class NOT consumer-gated (Phase-2 pattern is the load-bearing predicate, not full #87 PASSING, per feedback_construction_over_ratchets) * docs(briefs): Director scaffold-fill for R3 CI Layer 2 path-conditional gating Per PM ratification at gunbc#828 c4425726922 + Director ratification msg_a77c7f42 (Verification Mgr routing per feedback_parallel_representation_debt coherence). Bridge-debt with named dissolution trigger: when gate ci_uses_provable_minimal_affected_set_selection lands, the affected-set Introspect-lens output (canvas PR #2713) replaces the bridge's required_paths_regex column. Brief covers: - §0 scope: extend PR #2718's changes job, do not parallel - §1 mechanism: per-group skip_* boolean outputs + STEP-level if: on v3 - §2 inventory sources (slow-test-exemptions.txt + /tmp/v3-test-timings.log + NEW per-group required-paths mapping) - §3 per-dimension structural target — every entry has dimension: Dimension field matching lens enum (parallel-representation-debt prevention) - §4 hard constraints (8 invariants) - §5 acceptance - §6 decomposition (Mgr-fill recommendation: cost_lens pilot first) - §7 STOP-and-escalate criteria - §8 bridge-debt + dissolution path explicit Verification Mgr (clever-tern-670) fills inventory + per-group regex + dispatch. Director scaffold preserves coherence; Mgr finalizes per feedback_director_mgr_energy_input. * docs(briefs): fix Layer 2 YAML naming inconsistency (skip_cost → skip_cost_lens) Per cursor APPROVE_WITH_COMMENTS at sha 04c5b08 (review 9701): > The changes outputs define skip_cost, but the v3 step's if: uses > needs.changes.outputs.skip_cost_lens. That disagrees with the same brief's > post-dissolution sketch (skip_$group with cost_lens → skip_cost_lens, lines > 129-134). Not a formal invariant breach by itself, but it is easy for an > implementer to copy the wrong name and get an always-on/off step. Fix: normalize the example YAML outputs block to match the if: lines and the post-dissolution sketch. Naming convention: skip_<group_name> where <group_name> matches the per-group table's group_name column verbatim (no abbreviation). Updated all 4 example outputs: skip_lens → skip_complexity_lens (was vague; tied to specific group) skip_emit → skip_emit_target (matches starting template at §2) skip_parser → skip_parser_grammar (matches starting template) skip_cost → skip_cost_lens (matches if: line + post-dissolution sketch) Also added an inline comment documenting the naming convention so future copy-paste from the example stays mechanically correct. * docs(briefs): cite PM pre-staged Mgr-fill template (PR #2721) + converge pilot recommendation on Cluster B Per PM msg_bba47649 — pre-staged Mgr-fill template landed as PR #2721 (docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md, 220 lines). Two scaffold updates: 1. §2 (inventory sources): replaced 'PM pre-staged skeleton to be attached if/when available' speculative reference with explicit cite-and-link to the landed template doc. Describes what the PM template provides: - All 78 slow-test-exemptions.txt entries grouped into 9 clusters (A-I) - (test_pattern, dimension, required_paths_regex) skeleton table - 12 [Mgr-fill] placeholders for substrate-lens / R3-V L4/L7 / R1C-E / free-consequences cross-target tracing 2. §6 (decomposition): converged my prior cost_lens-first pilot recommendation with PM's Cluster B recommendation — these are the same family (Lane 2 Stage 2d symbolic cost = cost-lens). Updated wording to reflect Cluster naming + cross-citation to PM template's Cluster B detail. Added [Mgr-fill] placeholder resolution wave to decomposition. Inline sketch table retained as illustrative; defer to PM template for actual starting inventory. * WIP: gunbc Director * docs(briefs): fix singular dimension → Set<Dimension> per PM caught semantic violation PM (msg_ab551c52) surfaced codex RC on template PR #2721 (review #9707): singular 'dimension:' field violates locked-design §2 union semantics. A multi-dim consumer (e.g., LBP demonstration reading both complexity + cost) declared with singular dimension: cost would be silently skipped when only complexity changes — fail-open violation against P3. PM fixed their template at dedcf69: dimension → dimensions (Set<Dimension>), union-formula clarified, multi-dim rows expanded. This brief had the same singular semantics; absorbed the fix per PM recommendation so Verification Mgr inherits coherent dim-set semantic across both authority chain artifacts (brief + template). Changes: - §0 authority bullet: contains(single) → (∩ ≠ ∅) intersection-non-empty; dimension: Dimension → dimensions: Set<Dimension> - §2 table column rename + type spec + union semantics note + multi-dim consumer guidance - §2 starting template citation updated to reflect post-fix template at dedcf69 - §3 section header renamed; substantive paragraph explaining WHY Set<Dimension> not Dimension (cites PM caught violation + P3 fail-open framing) - §3 YAML example: jq script updated to set-intersection check - §4.5 hard constraint: dimensions: Set<Dimension> with members from enum; empty set invalid - §5 acceptance: every group has dimensions: Set<Dimension>; multi-dim fidelity language - §6 pilot description: 'singleton {cost} dimensions' phrasing; class wave reviewer-check language updated - §7 STOP: added multi-dim escalation path; explicit warning against defaulting to singleton {primary} - §8 surviving artifact: (group_name, dimensions) — set-typed column survives - inline illustrative table: explicit set-literal notation with multi-dim row example (lbp_demonstration: {complexity, cost}) Same authority chain absorbs cleanly: brief (primary) + template (data attachment) now both set-typed; Verification Mgr inherits coherent semantic. * docs(briefs): fix boolean polarity inversion + add polarity invariant per openai-pro RC on template PM (msg_9a188e22) surfaced openai-pro BLOCKING re-review (#9721) on template PR #2721 at 93080af — caught load-bearing boolean polarity inversion: brief stated skip_* formula as (affected ∩ row.dimensions) ≠ ∅ (skip when intersection NON-empty) while CI consumer wires if: skip != 'true' (run when skip is false). Net effect: literal-following Mgr/worker would wire the gate to silently skip AFFECTED tests when intersection is non-empty. TESTING.md + Boundary Discipline violation. PM fixed template at 262f42d (4 sites inverted; explicit polarity table added at §1/§3/§4/§5). Same risk on this brief (#2719) at the post-dissolution mapping site I authored when absorbing the prior dim-set fix at efacecd. Fix: §0 authority bullet (line 10, the inversion site): before: 'skip_* flags become (∩ ≠ ∅)' [INVERTED — fail-open] after: 'skip_* flags become skip_<group> = (∩ = ∅)' [canonical] + explicit polarity check note + carrier-vs-contract explanation + skip-form / run-form equivalence stated §3 substantive paragraph (after Set<Dimension> WHY): added Polarity invariant block citing PM's caught inversion + 262f42d fix + explicit warning that skip = (∩ ≠ ∅) is the canonical fail-open boolean-polarity bug pattern. §4 hard constraint #5 (dimensions field): added inline Polarity invariant restating the canonical skip-form + run-form equivalent + 'never invert' clause. §5 acceptance: added 'Polarity check passes' criterion enumerating the acceptable forms + naming the inverted form as the fail-open pattern to reject in review. Self-test text clarified: cost-dimension groups run, other-dimension groups skip (verifies correct polarity in actual gate). YAML example at §3 (lines 139-149) was already polarity-correct (skip iff intersection empty; skip=true when intersection empty) so unchanged. Single-pass absorption per PM recommendation — both brief and template now lockstep on polarity semantics. Verification Mgr inherits both files without polarity mismatch in finalization. * WIP: gunbc Director * docs(briefs): align §0 example names with §1 naming convention (cursor exploratory) Per cursor APPROVE exploratory observation on PR #2719 sha 13b0db9 (review #9732): §0 line 25 illustrative outputs used abbreviated names (skip_lens / skip_emit / skip_parser) while §1 line 53-54 establishes strict 'skip_<group_name>' naming convention matching the per-group table verbatim. Non-policy violation per cursor but tightening avoids ambiguity for implementer. Fix: replace abbreviated names with full-form (skip_cost_lens / skip_emit_target / skip_parser_grammar) + cross-reference §1 naming convention in the same sentence. Brief now consistent across all naming sites. * docs(briefs): add P3 fail-closed shared-infrastructure full-run bucket per codex BLOCKING codex REQUEST_CHANGES on PR #2719 at sha 52c6cf0 (review #9744): Line 102 narrowed required-paths inventory to 'src/v3/*' deps only; the illustrative table at lines 114-118 followed that shape. A PR that changes shared test infrastructure or selection machinery outside src/v3/* (.github/workflows/ci.yml, scripts/*, Cargo.lock, rust-toolchain.toml, etc.) would be classified as 'unaffected' for every per-group regex and silently skip tests whose behavior actually changed. That's the fail-open boundary class P3 forbids + TESTING.md behavior-driven discipline violation. Real correctness issue in the proposed mechanism, not just an implementation detail. Fix: add shared-infrastructure full-run fail-closed bucket as the join-point that catches inter-group / cross-cutting changes: §2 (inventory sources): added 'Shared-infrastructure full-run fail-closed bucket' subsection with explicit mechanism — changes job computes force_full_run = (any changed file matches shared-infra regex); when true, all per-group skip_* short-circuit to false. Regex spec: ^(\.github/.*|scripts/.*|Cargo\.(toml|lock)|rust-toolchain\.toml| \.cargo/.*|build\.rs)$. Names the structural rationale: per-group regexes cover ONLY their own src/v3/* deps; the full-run trigger is the join-point. Fail-closed by construction. §4 hard constraint #9 (new): formalizes the invariant + 'never collapse the full-run trigger into per-group regexes' (structural fail-open shape). §5 acceptance: added 'Shared-infrastructure full-run check passes' as separate criterion + self-test case (c) — a PR touching only .github/workflows/ci.yml or Cargo.lock or scripts/check-test-timeout.sh MUST run all test groups. Expanded self-test from 3 to 4 cases (a/b/c/d). §2 added [Mgr-fill]: validate shared-infra regex against representative recent PRs. Single-pass absorption; brief now P3 fail-closed at the cross-cutting boundary. * WIP: gunbc Director * docs(briefs): fix two openai-pro BLOCKINGs — harness-arm in shared-infra regex + cargo test substring not glob openai-pro REQUEST_CHANGES on PR #2719 at sha 0d3b44b (review #9749 + manual c4426188322): BLOCKING #1 (P3 Fail-Closed): brief at line 104 names 'harness code' as a class to catch in full-run regex but the actual regex at line 109 had no harness/test-selection arm. Harness-only changes (e.g., to tests/integration/common/* or sg0_census_test.rs) would miss both full-run regex AND per-group regexes — silent skip. BLOCKING #2 (TESTING.md fail-closed CI): test_pattern field documented as 'cargo test arg pattern' but examples used glob-looking syntax (cost_lens_*, *_emit_*). Cargo positional test arg is a libtest SUBSTRING filter, not a glob. Worker following the brief literally would produce a step that runs zero intended tests + exits successfully — silent skip converting 'selected group tested' into 'selected group filtered out.' Fixes: #1 (harness arm in shared-infra regex): - §2 mechanism: extended regex to include src/v3/compiler/tests/integration/common/.*, sg0_census_test.rs, test_runner_test.rs, t_pb_b_1_dag_runner_test.rs, integration.rs, integration test entry points - §2 new paragraph naming the harness/test-selection-machinery arms explicitly + hard rule: harness-class files MUST never appear in a per-group required_paths_regex - §4 hard constraint #9: extended invariant to include harness class with explicit file list - §5 acceptance: extended self-test case (c) to include harness-class example (common/cached_compile.rs) + explicit verification list #2 (cargo test substring, not glob): - §1 YAML examples: cost_lens_* → cost_lens; *_emit_* → emit; added IMPORTANT comment explaining libtest substring semantics + forbidding glob syntax - §2 test_pattern column spec: re-documented as 'libtest test-name SUBSTRING filter (NOT a glob)' with cost_lens example + glob forbiddance + --exact alternative - §2 inline illustrative table: cost_lens_* → cost_lens (and others); added trailing comment naming substring semantics - §4 new hard constraint #10: test_pattern is substring filter not glob; self-test that the value substitutes verbatim into cargo test and runs positive number of tests - §5 acceptance: new 'test_pattern substring-filter check passes' criterion with empirical pilot-wave validation requirement Brief now P3 fail-closed at both the boundary (shared-infra full-run including harness) AND the selector (substring filter that workers can copy verbatim without silent zero-test execution). Single-absorption pass; awaiting fresh review at new HEAD. * docs(briefs): reframe PM template citation per codex P1/P2 — template is on PR #2721, NOT yet landed on main codex REQUEST_CHANGES on PR #2719 (review #9754): Line 128 named docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md as a 'landed' starting authority, but git ls-tree origin/main returns no blob and git ls-files returns nothing. A worker following this brief would be sent to a non-existent source of truth — INVARIANTS P1/P2 authority-grounding violation in a dispatch document. Verified at HEAD: - git ls-tree origin/main -- docs/briefs/r3-ci-layer-2-pm-prestaged-mgr-fill-template.md → empty - gh pr view 2721 → state=OPEN, mergedAt=null - Template lives on PR #2721's branch only Fix: reframe the template citation to acknowledge PR #2721 is open-not-landed. - 'landed via PR #2721' → 'open as PR #2721 ... NOT yet landed on main' - Added codex BLOCKING citation + verification receipt (git ls-tree result) - Added explicit authority caveat: Verification Mgr finalization MUST coordinate merge sequencing — (a) merge #2721 first, OR (b) read from PR #2721 branch until it merges - Named PM (deep-wolf-155) as PR #2721 author + cross-link for merge coordination - Cited sha 262f42d (PR #2721 post-fix state per PM msg_125e3aa5) Brief now accurately grounded on the actual file location (PR #2721 branch) with merge-sequencing guidance for Mgr finalization. Authority chain honest about in-flight vs landed state. * WIP: gunbc Director * docs(briefs): absorb 3 BLOCKING findings (Brian + codex) — R4 lifecycle reframe + canonical 2-step + count fix Brian inline BLOCKING #1 + codex BLOCKING #1 (P5 dissolution-trigger authority): brief framed dissolution as R3 close-blocking gate 'ci_uses_provable_minimal_affected_set_selection' but docs/design-affected-set-lens.md:3 = 'R4 wishlist', :354 = 'CI integration sketch (deferred to R4 full delivery)', :366 = 'CI integration is R4 full-delivery work'. No ROADMAP authority exists for the cited gate name — that was Director-tier speculation. Brian inline BLOCKING #2 + codex BLOCKING #2 (Facts Flow Forward / surviving schema): §3 post-dissolution sketch only encoded dimension intersection, silently dropping NodeRef intersection. Canonical 2-step per design §5:359 requires BOTH (TestClaim.refs ∩ affected_nodes) ≠ ∅ AND (TestClaim.dims ∩ changed.dims) ≠ ∅. Reducing surviving schema to (group_name, dimensions) too early. codex non-blocking: slow-test-exemptions.txt count cited as 78 (PM template value); actual is 80 at 2026-05-12T00:50Z (verified locally: grep -v '^#' ... | grep -v '^$' | wc -l = 80). Fixes (single absorption pass): §0 'Bridge-debt → dissolution lifecycle' bullet: - Reframed from 'R3 close-blocking gate' to 'R4-bounded dissolution lifecycle (NOT R3 close)' with explicit citation of design doc :3 + :354 + :366. Names R4.B as R4 owner. Removes the speculative gate name. Names Brian's BLOCKING #1 absorption. §0 NEW 'Post-dissolution selection semantics (canonical 2-step join)' bullet: explicit NodeRef + dimension joins per design :359; run formula; skip formula; bridge coarseness acknowledgment (path-regex over-approximates canonical lens; fail-closed-safe but coarser). Names Brian's BLOCKING #2 absorption. §0 polarity check bullet: updated skip-form to reflect 2-step (NodeRef-empty OR dim-empty ⇒ unaffected ⇒ skip). §2 inventory source (a): count 78 → 80 at 3 sites (replace_all), with explanation that count grows over time + Mgr re-runs grep at finalization rather than relying on stale citations. §2 table column spec: added 'testclaim_references' as 5th column. Cited Brian's BLOCKING #2; explains bridge-tier proxy vs post-dissolution proxy. §2 [Mgr-fill]: extended to require testclaim_references computation per canonical 2-step. §3 YAML post-dissolution sketch: rewrote classify step to compose BOTH NodeRef AND dimension intersections via jq + cite Brian's BLOCKING #2 absorption inline. Header comment names R4.B authority and acknowledges no current ROADMAP gate ID. §4 #4 PR-body bridge-debt template: reworded from 'R3 close-blocking gate' to 'R4.B Introspect-lens saturation lane CI integration delivery; NOT R3 close-blocking.' §8 surviving artifact: corrected from (group_name, dimensions) to (group_name, dimensions, testclaim_references) per canonical; cited Brian's BLOCKING #2. Removed all references to 'ci_uses_provable_minimal_affected_set_selection' as a current ROADMAP gate name; replaced with R4.B owning-lane references + explicit acknowledgment of authority gap. Brief now P5-honest: dissolution trigger is checkable (R4.B owning lane) even if no concrete gate ID yet; surviving schema preserves both lens join inputs per canonical algorithm. * docs(briefs): reconcile §3 substantive + §7 STOP with §0/§8 — surviving schema is 3-column (cursor internal-consistency catch) cursor REQUEST_CHANGES on PR #2719 sha 540113f (review #9767): Two internal contradictions surfaced from my partial absorption of Brian's BLOCKING #2: (a) §3 substantive paragraph still said '(group_name, dimensions) mapping survives the dissolution — only required_paths_regex column gets retired' contradicting §0 + §8 which were updated to 3-column (group_name, dimensions, testclaim_references). (b) §7 STOP bullet referenced 'Layer 2 dissolution shape doesn't match (group_name, dimensions) schema' — 2-column framing, same contradiction. Fix: §3 substantive paragraph (around the parallel-representation-debt rationale): - 2-column → 3-column framing - both dimensions AND testclaim_references must be authored - cite design §:359 canonical 2-step join - cite cursor internal-consistency catch alongside Brian's BLOCKING #2 §7 STOP escalation bullet: - (group_name, dimensions) → (group_name, dimensions, testclaim_references) + cite canonical 2-step join Verified via grep: all remaining references are within meta-statements explicitly documenting the removal (line 10 + line 268); no live references remain. All appearances are either in updated 3-column contexts or in meta-statements referencing the absorption (line 15 catch citation). Brief now internally coherent across §0, §3, §7, §8 on: - dissolution trigger (R4.B owning lane, NOT removed-gate-name) - surviving schema (3 columns including testclaim_references) - canonical 2-step join semantics * docs(briefs): fix stale 78 inventory references at §2 lines 114 + 141 per openai-pro BLOCKING openai-pro REQUEST_CHANGES on PR #2719 sha 8ae7938 (review #9779): Brief had stale '78 active >2s entries' at line 114 + 'All 78 ... entries' at line 141, despite §0 line 19 + §2 line 157 stating live count is 80 and Mgr should re-run count at finalization. A worker following §2 literally could build the gating table from stale 78-entry basis, omitting 2 slow-test entries — fail-open shape against the brief's own P3 fail-closed contract (under-inventory = exemption falls in neither per-group regex nor full-run bucket = silently skipped). Fix: §2 inventory source (a) (line 114): replaced 'start with the 78 active >2s entries' with 'start with the current live count of active >2s entries (Mgr MUST re-run grep ... | wc -l at finalization; 80 at 2026-05-12T00:50Z but count grows; do NOT cite the stale 78 from PM template PR #2721 or any earlier reference)'. Added 'fail-closed completeness invariant' inline: every active exemption MUST appear in either a per-group required_paths_regex OR the harness/shared-infra full-run bucket; no exemption left unclassified. §2 PM template description (line 141): 'All 78 entries' → 'PM-grouped entries (PM template snapshot was 78 at template authoring time; live count grows — Mgr re-verifies via wc -l at finalization, NOT this stale historical reference)'. Added note that the 9-cluster taxonomy survives count growth; Mgr maps new entries to existing clusters or escalates if a new cluster surface emerges. Brief is now internally consistent on inventory-count freshness: - §0 line 19: live 80 with verification command - §2 line 114: re-run command at finalization; explicit do-not-cite-78 instruction - §2 line 141: PM template snapshot historical; live count grows - §2 line 157 (Mgr-fill): re-run grep, don't trust stale citations 12th distinct review-class catch this polish cycle: inventory-citation freshness as fail-closed completeness invariant. * docs(briefs): §5 acceptance requires testclaim_references explicitly per codex BLOCKING #9780 codex REQUEST_CHANGES on PR #2719 sha 8ae7938 (review #9780): Finding #1 (stale 78 at lines 114 + 141) already fixed at prior commit 487d175; codex finding overlaps with openai-pro #9779 absorbed before. Finding #2 (new): §5 acceptance at line 228 only required dimensions: Set<Dimension> on each group entry, NOT testclaim_references: Set<NodeRef>, even though the brief makes that column load-bearing at: - §0 line 104 (post-dissolution selection canonical 2-step) - §3 line 178 (substantive paragraph: 3-column surviving schema) - §8 line 269 (surviving artifact 3-column) A Mgr reading §5 acceptance literally could call PR-set 'done' with dimensions-only column population — that's the dimensions-only closeout codex flags as facts-flow-forward violation. Fix: §5 acceptance adds new explicit criterion: 'Every group entry has testclaim_references: Set<NodeRef> field' with explicit citation chain (design §:359 + Brian BLOCKING #2 + codex BLOCKING #9780). Includes bridge-tier-proxy vs post-dissolution-proxy note. Includes 'Dimensions-only acceptance closeout is rejected: P2 facts-flow-forward requires both lens-join inputs.' §5 acceptance now coherent with §0/§3/§8 on the 3-column surviving schema; no path to 'done' that skips testclaim_references. 13th distinct review-class catch this polish cycle: acceptance-vs-substantive-text divergence on load-bearing fields. * docs(briefs): Director scaffold for cold-v3 rebuild coordinator (Phase 3-pattern; per-cut child workers) Per PM greenlight msg_07f73de0 + Brian operator greenlight at gunbc#846 reply (~01:25Z 2026-05-12).

Brian: P5 receipt required for new/expanded src/v3 Rust. Codex: require P5 receipt OR state SG-0-neutral without helper expansion. (2) #2725 line 83 (§3 acceptance final bullet) — hard-codes ratchet floor ≤80 (pre-hot-fix baseline), preserving stale debt. Brian: current main has 84 active exemptions with 20 hot-fix rows; post-rebuild floor should be recomputed, not preserved at 80. Codex: derive final floor from live non-hot-fix exemptions at Mgr finalization; delete hard-coded ≤80. (3) #2719 line 217 (§4 hard constraint #5 Polarity invariant sub-bullet) — restates skip formula as dimension-only, contradicting two-step NodeRef+dimension contract. Brian: silently drops testclaim_references in violation of P2 Facts Flow Forward. Codex: rewrite every formula to skip when refs∩nodes empty OR dims∩changed_dims empty. (Partial-absorption- residual: cursor's catch on #2725 review #9799 was fixed at §3 substantive paragraph at commit 403833e but didn't propagate to §4 constraint #5 sub-bullet at line 217 — different polarity-mentioning site within the same brief.) Fixes (single-pass per discipline; same pattern as prior 14-catch cycle): #2725 constraint #4 (line 70) rewrite: - 'No new hand-Rust beyond shared-fixture helpers' (carve-out) → 'Shared-fixture helpers require P5 receipt + SG-0-neutrality' - Per-PR P5 receipt explicit: (a) helper LOC delta cited, (b) dissolution path named (helper retires when cluster's pattern lands in .dag TestClaim authority), (c) SG-0 census-delta computation showing net ≤ 0 - SG-0-neutrality enforcement: helpers may add lines but net delta ≤ 0 (helper additions offset by exemption-row retirements + ratchet-down). Net positive = escalate (substrate-shape signal) #2725 §3 acceptance final bullet (line 83) rewrite: - 'ratchet floor returned to ≤80 (pre-hot-fix baseline)' → 'ratchet floor recomputed DYNAMICALLY from live state at activation' - Concrete computation: starts at current main HEAD's TEST_TIMEOUT_MAX_EXEMPTIONS (84 at dfbc010; verify via grep at Mgr finalization); each rebuild PR decrements by N (cuts rebuilt that PR); post-all-20-rebuild target = (value at activation) - 20 (e.g., 64 at current state) - Removed '≤80 pre-hot-fix baseline' framing - Explicit acknowledgment: 80 was ITSELF stale debt; 16 non-hot-fix exemptions have separate paydown owners; rebuild does NOT freeze goal at 80; long-run target per feedback_pb_zero_is_r3_close_target is 0 #2719 §4 constraint #5 (line 217) rewrite: - Header changed: '...dimensions: Set<Dimension> field on every group entry' → '...dimensions: Set<Dimension> + testclaim_references: Set<NodeRef> fields on every group entry' - Polarity invariant rewritten to canonical 2-step join (BOTH NodeRef AND dimension intersections; skip = either empty) - Two fail-open bug patterns explicitly named: (a) inversion (b) dimension-only collapse - Bridge-tier proxy framing preserved (path-regex over-approximates canonical; fail-closed-safe coarseness) 15th + 16th + 17th distinct review-class catches this polish cycle (16 on #2719 brief; #15 on rebuild scaffold #2725): - #15 (BLOCKING #1): shared-fixture helper P5 receipt obligation - #16 (BLOCKING #2): dynamic ratchet floor recomputation - #17 (BLOCKING #3): polarity-residual at second site (partial-absorption- residual within partial-absorption-fix; pattern: 'when canonical algorithm gets corrected, ENUMERATE all polarity-mentioning sites' is the discipline) * docs(briefs): apply §3 polarity 2-step rewrite on rebuild-scaffold branch (cursor #9815 catch + #2719-branch parity) cursor APPROVE_WITH_COMMENTS on #2725 review #9815 caught that line 208 (§3 substantive Polarity invariant paragraph) on rebuild-scaffold branch's copy of #2719 brief was still dimensions-only — even though line 217 (§4 constraint #5 sub-bullet) was updated to canonical 2-step in commit 900d5a3. Root cause: my prior #2719 polarity fix at commit 403833e was on #2719's own branch (director/r3-ci-layer-2-path-conditional-gating-scaffold) and never propagated to main → never reached rebuild-scaffold branch's copy of the #2719 brief brought in via main-merge. Applied same §3 polarity rewrite on rebuild-scaffold branch for parity with #2719 branch's content: - run = (refs ∩ nodes) ≠ ∅ AND (dims ∩ changed_dims) ≠ ∅ - skip = ¬run = either intersection ∅ - Explicit naming of TWO fail-open patterns: (a) inversion (b) dimension-only collapse - Bridge-tier proxy framing preserved Cross-branch state now consistent: - #2719 branch (director/r3-ci-layer-2-path-conditional-gating-scaffold) has canonical 2-step at lines 208 + 229 (via 403833e) - #2725 branch (director/r3-ci-cold-v3-rebuild-coordinator-scaffold) has canonical 2-step at lines 208 + 229 (via 900d5a3 + this commit) Both branches' copies of #2719 brief now structurally identical on polarity semantics. Will fully reconcile at merge time if both PRs land separately. 18th distinct review-class catch this polish cycle: cross-branch-divergence-on-shared-doc — when two Director-scaffold PRs both touch a shared brief (one via direct edit, one via main-merge), fixes on one branch must explicitly propagate to the other branch OR the shared content reconciles at merge time. Pattern: 'shared doc in two PRs requires explicit cross-branch parity discipline'. * docs(briefs): fix Phase 4 ratchet sweep residual ≤80 → dynamic (value − 20) per codex BLOCKING #9827 codex BLOCKING on #2725 review #9827 caught residual at line 92 (§4 Phase 4 ratchet sweep description) — still said 'back to ≤80' despite §3 acceptance bullet's stale-baseline correction (which removed the ≤80 framing in favor of dynamic '(value at activation) - 20'). Same partial-absorption-residual class as cursor's earlier catches: fixing the §3 acceptance bullet correction didn't propagate to §4 Phase 4 description; sites referring to the same stale value need parallel updates. Fix: Phase 4 description now uses dynamic '(value at activation) − 20' (e.g., 64 at current state of 84) with explicit acknowledgment that 80 was itself stale debt + cross-link to feedback_pb_zero_is_r3_close_target naming the long-run target = 0 exemptions. 21st distinct review-class catch this polish cycle: phase-description-vs-acceptance-bullet-residual — when an acceptance bullet gets a corrected target, the phase descriptions that motivate phases toward that target need parallel updates. Pattern: 'when target gets corrected, ENUMERATE all phase descriptions / decomposition / STOP criteria that motivate work toward that target.' * fix(#2725): cursor BLOCKING #9834 absorbed Two findings addressed: 1. Line 76 copy-paste slip: "The Layer 2 PR-set is acceptable when:" in a cold-v3 rebuild brief. Changed to "The cold-v3 rebuild PR-set is acceptable when:" to match brief's actual scope. INVARIANTS.md P1 modeling faithfulness for dispatch authority. 2. Line 70 prose tightening: SG-0-neutrality framing previously conflated SG-0 census mechanism with exemption-list mechanism ("helper additions offset by exemption-row retirements + ratchet-down"). These are DIFFERENT bookkeeping: SG-0 counts hand-Rust files/lines per sg0_census_test.rs; exemption-row retirement only reduces slow-test-exemptions.txt count. Corrected prose: helper-LOC additions in common/* MUST be offset by EQUAL- or-greater LOC reductions in per-test files consuming the helper (shared fixture extraction → per-test setup boilerplate dropped). Exemption-row retirement + ratchet-down are independent obligations per constraint #2 and do NOT count toward SG-0 census-delta. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: gunbc Director * fix(#2725): openai-pro REQUEST_CHANGES — 2 BLOCKING findings absorbed Finding 1 (P3 Fail-Closed): Layer 2 shared-infra regex anchored Cargo.toml/ Cargo.lock/build.rs to workspace-root only. Crate-local manifests (e.g., src/v3/compiler/build.rs per CODING.md:319) would NOT match, silently skipping tests for crate-local manifest/build-script changes — fail-open boundary class P3 forbids. Fixed by changing the anchored alternates to use (.*/)?Cargo\.(toml|lock) and (.*/)?build\.rs — non-capturing optional path prefix matches both root-level AND any-depth crate-local files. Finding 2 (ratchet/test discipline): Cold-rebuild brief had execution-path contradiction. §2#2 + §3 require same-PR lockstep ratchet-down. But §4 Phase 4 description said "drops TEST_TIMEOUT_MAX_EXEMPTIONS to (activation) - 20", creating a fail-open path where workers could defer per-PR ratchet- down to Phase 4 cleanup. Reframed Phase 4 as VERIFICATION + budget-tighten (NOT decrement). Phase 4 verifies cumulative ratchet matches target + drops cold-CI --timeout. If verification finds mismatch, escalate per §5 (per-PR discipline violation), do NOT silently patch.

* docs(briefs): R3 CI Layer 2 — PM pre-staged Mgr-fill template Author the pre-staged Mgr-fill reference doc Director accepted via msg_4623068b at 22:54Z (greenlight on PM's pre-staged-skeleton offer from gunbc#828 c4425726922). Director will cite this file in their forthcoming worker brief (`docs/briefs/r3-ci-layer-2-path-conditional- gating-worker.md`) as the starting template for Verification Mgr (clever-tern-670) inventory finalization. Content: - §1 affected-set lens Dimension enum reference (cite design doc §2) - §2 slow-test inventory grouped into 9 clusters (78 entries from scripts/slow-test-exemptions.txt) - §3 path-mapping skeleton table — (test_pattern, dimension, required_paths_regex, confidence, dissolution_note).

This conflicts with the locked design at `docs/design-affected-set-lens.md` §2: affected_set(Dag_before, Dag_after) = ⋃ over dim in {Value, Cost, Complexity, Effect, Refinement} affected_set(Dag_before, Dag_after, dim) A test that reads BOTH Cost AND Complexity (e.g., D-cluster LBP demonstration; lane2_stage_2f composed-matches-lens) would be silently skipped when only Complexity changes if its dimension is narrowed to "Cost." That's `INVARIANTS.md` P2 single-authority violation against the locked lens design. Fixes: - §1: rewrite from "exactly one primary dimension" to "dimensions is Set<Dimension> = full read-set; affectedness is union semantics" - Header bullet: hard constraint reframed — multi-dim REQUIRED when consumer reads multi; post-dissolution math is `(affected ∩ row.dimensions) ≠ ∅` - §3 table: column rename `dimension` → `dimensions`; rows updated: - D-cluster LBP, lens_cost_target_realization, cost_lens_consumer: expanded to multi-dim sets [Complexity, Cost], [Cost, Value] - lane2_stage_2f_dimension: [Complexity, Cost] (composed-matches-lens) - F-`m0_acceptance` + I-`thesis_validation_test`: full 5-dim set (compile-boundary + thesis-level read every dim) - G-`t_las_crdt_cost_basis_demo`: [Cost, Effect, Value] - G-`r3_free_consequences_second_batch`: [Cost, Value] - H-`t_ci_workflow_as_data_demo`: [Value, Cost] (DimensionReport timing) - All single-dim rows (A, B, Most-C, etc.): formatted as set `[Cost]` - §4 Open question 1: rewrite to forbid narrowing, mandate ADD-when-doubt - §5 acceptance: add dim-set-semantics + union-formula checks - §6 STOP triggers: add "tempted to narrow set → STOP and EXPAND" Director's Layer 2 brief at PR #2719 has the same singular-`dimension:` shape and likely has the same finding waiting to surface; will flag to Director after this lands.

A Mgr/worker following the brief literally would have wired the CI gate backward, silently skipping affected tests — TESTING.md "test selection must not skip affected behavior" violation + Boundary Discipline violation (boolean carrier name and contract encoded opposite meanings). **The bug**: 4 places stated post-dissolution `skip_<cluster>` formula as `(affected_dimensions ∩ group.dimensions) ≠ ∅` (skip when intersection NON-empty), while the CI consumer wires `if: skip_<cluster> != 'true'` (run when skip is NOT true). Combined: when intersection is non-empty (= affected), skip=true → tests don't run → affected tests silently skipped. **The fix**: invert the formula to `(intersection = ∅)` (skip when intersection IS empty = no affected dim that this cluster reads). The CI gate semantics stay the same; the polarity correction is on the post-dissolution lens mapping. Sites corrected: - §1 hard-constraint para (line 9): replaced "(non-empty intersection means run)" with an explicit Boolean polarity block defining `skip = (intersection = ∅)` and equivalent `run = (intersection ≠ ∅)` - §3 path-mapping intro (was line 132, now 142): same polarity fix + "Equivalently: `run = (intersection ≠ ∅)`" - §4 open-question 4 (was line 186, now 196): "skip_<cluster> becomes `(intersection ≠ ∅)`" → `(intersection = ∅)` with explicit "same polarity: skip when no affected dim" note - §5 acceptance (was line 206, now 216): same polarity fix + explicit "inverting the polarity silently skips affected tests" warning All 4 references now consistent. Polarity table: intersection = ∅ → skip=true → "do not run" (NOT affected, safe to skip) intersection ≠ ∅ → skip=false → "run" (affected, must run) Director's brief #2719 likely has the same polarity issue and will need parallel fix from the same authority chain. Flagging separately.

A worker following the brief could implement disjunction (any-row-empty = skip cluster) which would silently skip the OTHER affected rows in the cluster when only one row is unaffected. Fix: explicit conjunction predicate in §3 + §4 + §5 + §6: skip_<cluster> = ∀ row ∈ cluster : (changed_files ∩ row.regex) = ∅ Equivalently: run_<cluster> = ∃ row ∈ cluster : row affected. **(2) Path regexes PM-authored without source-tree verification**: PM concrete `required_paths_regex` values in §3 were manually authored from the inventory SHA references without validation against actual paths in the source tree. Workers might wire CI gates against stale paths. Fix: explicit Mgr-verification discipline in §3 + §4 + §5 + §6: - Workers MUST validate each concrete regex against source tree at HEAD before CI implementation - Unverified or unverifiable regexes → `.*` per conservative fail-closed default - Confidence column treated as audit priority (low → `.*` first, medium → audit then decide, high → audit but likely fine) - Validation record kept (PR description or commit message) Both fixes preserve the locked-design polarity from earlier revisions: - Per-row formula stays `(intersection = ∅)` for skip semantic - Cluster aggregation is conjunction over rows (∀) - Run formula is the structural complement (∃ ↔ ≠ ∅) All 4 places updated: §3 path-mapping skeleton intro + §4 mechanism + §5 acceptance + §6 STOP triggers.

Mechanism of the bug: - Markdown tables use `|` as column separator - To put a literal `|` IN a cell (outside backticks), you escape with `\|` - PM authored the regex with `\|` thinking the markdown-table escape was needed, but the regex is INSIDE backticks (code span) which preserves pipe character literally - A worker copying the regex into ci.yml would silently miss tokenize.dag changes (only matches literal `compiler|std/tokenize.dag`) Fix: drop the unnecessary `\` escape; markdown code spans preserve `|` literally. Now regex correctly reads `src/v3/(compiler|std)/tokenize.dag` — alternation between src/v3/compiler/tokenize.dag and src/v3/std/tokenize.dag, both of which exist per the source tree verified at 45fc195. Mitigation: the template's own validation discipline at §3 + §5 §6 (workers MUST validate regex against live source tree before CI implementation) would have caught this, but per openai-pro's read "the concrete row should still not carry a known-bad example" — fair.

My prior open-enum fix (c61a7ed) updated §1/§5/§6 to ALLOW user- defined dims but I didn't fix THIS row to USE one. Per the just- established 'carry the dim, don't narrow' framing in §6, this row should carry `[Value, Cost, Timing]` (or just `[Value, Timing]` if Cost is sufficiently distinct from Timing in the test). **Why it's load-bearing**: a future timing-only delta (e.g., DimensionReport schema change touching only timing fields, not Cost) would be 'affected' for this test under the lens but the prior row narrowed Timing → Cost → if Cost.affected = empty but Timing.affected non-empty, test would be silently skipped (TESTING.md violation + THESIS user-defined-dims framing violation). Fix: - Row dimensions: `[Value, Cost]` → `[Value, Cost, Timing]` - Row dissolution-note: explicit annotation citing `DimensionReport<TimingMeasurement>` + `ci_modeled_timing` user- defined dim + the carrying-vs-narrowing rationale - Self-references this template's own open-enum support per §1 — the row is now an in-table demonstration of the open-enum framing (consistency between framing and example) This also re-stress-tests cluster aggregation: cluster H aggregates over multiple rows including this Timing-carrying row, so cluster- level skip computation correctly fail-closes when ANY row's dim intersects with affected_dims.

This template (PR #2721) had the same structural issue: most PM- authored rows have arms (1) deps + (2) test-source but lack arm (3) `tests/dag/*.dag` fixture explicitly. Per Director's canonical worker-brief discipline (PR #2727), this mirrors the gap and adds the 3-arm completeness invariant to align. Updates: - §3 path-mapping intro: explicit 3-arm completeness invariant + per- arm fail-open semantics + audit note that PM-authored rows in §3 below need Mgr fixture-arm audit for tests reading from `tests/dag/*.dag` (e.g., `t_pb_b_1_dag_runner_test` consumes `tests/dag/t_pb_b_1_*.dag`) - §5 acceptance: new checklist item — every concrete regex includes arms (1) + (2) + (3) where applicable; Mgr-fill rejects missing arms 2/3 - §6 STOP triggers: two new STOP triggers for missing test-source arm OR missing fixture-arm-when-applicable - Cross-link to Director PR #2727 / #2719 for canonical framing This codifies but does NOT retrofit existing §3 rows — that's Mgr-fill audit work (per the §3 disclaimer + Mgr-fill discipline).

The PR #2750 cascade landed the 6 NEW T-WAD FULL gates (#98–#103) in: - r3-structure.md §Acceptance T-Workflow-As-Data bullets (lines 172-177) - r3-program-plan.md §1.8 ledger rows - r3-program-plan.md count propagation (§0/§1.5/§1.6/§1.7/§5.2/§10/§Q1) But the cascade missed two lane-DEFINITION gate lists in r3-structure.md that ALSO enumerate T-WAD closure gates: - Line 41 (numbered lane list, T-WAD entry) - Line 222 (T-WAD row in §"Lane structure" table) Both listed only the original 4 pre-FULL gates (workflow_substrate_carriers_landed / timing_lens_carrier_landed / ci_workflow_modeled_as_dag / shared_external_attachment_pattern_documented). Reviewers reading either list would not see the 6 NEW gates — INVARIANTS P2 single-authority gap. Fix: convert both lane-definition lists to pointer-only references back to §Acceptance T-WAD as the canonical gate list. Rationale: §Acceptance is the authority anchor (per INVARIANTS P2 + sister r3-program-plan.md §1.8); duplication in lane-definition lists would re-introduce drift the cascade is closing. Also augmented both lane-definition entries with FULL R3-close elevation 2026-05-12 framing + multi-Mgr ownership (Substrate Mgr Slices 4-5/8 + Verification Mgr Slice 7 affected-set + Debt-Paydown Mgr Slice 6 sub-component).

The scope doc exists on PR #2744's branch (in flight) but not on origin/main yet. Codex correctly notes the dangling cross-reference against current main. Fix: add explicit "(scope doc landing via in-flight PR #2744)" qualifier so future readers know the citation is forward-referencing a known in-flight PR rather than a typo or missing doc.

The earlier qualifier fix ("scope doc landing via in-flight PR #2744") acknowledged the dangling reference but didn't resolve the structural P2/P5 violation — the gate description still CITED an authority that doesn't exist on origin/main, which is the merge target. Audit: grepped both docs for refs to files that don't exist on origin/main: - docs/r3-structure.md:172 — `docs/r3-t-workflow-as-data-full-r3-close-scope.md` (PR #2744) - docs/r3-program-plan.md:326 — `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md` (PR #2744) Fix: replace both file-path references with PR-number anchors. PR numbers are stable references; file paths become valid only post-merge. Gate descriptions are self-contained without the cross-references (the (a)/(b)/(c) enumeration + supporting framing already conveys the gate's substance). - r3-structure.md:172: "per `docs/r3-t-workflow-as-data-full-r3-close-scope.md` §1 — scope doc landing via in-flight PR #2744" → "in-flight scope authority at PR #2744 §1" - r3-program-plan.md:326: "WI-2 implementation: `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md`" → "WI-2 implementation: in-flight via PR #2744 (brief lands with the scope-doc)" Both gates retain full substantive content; only the file-path crutches are removed. When PR #2744 merges and the files exist on main, future authors may re-add file refs cleanly — but the gate descriptions never needed them as load-bearing authority.

That framing conflicts with Workflow being a semantic platform carrier — current ci.yml carries comments / blank-line whitespace / key ordering quirks that aren't in the semantic model. Per P1/P2: - silent loss: emission drops comments → emitted YAML ≠ current ci.yml (not byte-equivalent, falsifies the claim) - second byte authority: parallel model captures formatting → P1 violation (CI-semantic fact lives outside the canonical carrier) Reframe to two distinct correctness conditions: 1. External semantic-equivalence (one-time, migration-axis): emitted YAML is semantically equivalent to current ci.yml when consumed by GitHub Actions (same triggers, jobs, steps, runners, conditions, permissions, matrix structure). Non-semantic facts in pre-migration ci.yml are DISCARDED — they are not load-bearing CI logic. 2. Internal byte-identity (regression-axis): committed artifact is byte-identical to FRESH projection output (regression-guard gate already in §1 row ci_yml_hand_authority_dissolved option (b) — correctly framed there). Discriminator restored: byte-identity is INTERNAL to the substrate (projection-output ↔ committed-artifact), not EXTERNAL (substrate-output ↔ legacy hand-authored content). Load-bearing comments in current ci.yml (workaround explanations, dissolution-trigger pointers) must migrate into substrate as modeled facts (structured Notes on the carrier OR inlined documentation in dsl/gunbc/ci_emission.dag) — they MUST NOT become parallel byte-authority alongside the semantic carrier. Cascade per feedback_dissolution_authority_not_file_presence: same conflation pattern appeared in BOTH the scope-doc §3 line 114 AND the WI-1 brief §Scope.1 line 29; both reframed in lockstep.

Even after the earlier b2bc281 fix locked CIPipeline OUT as a valid source, the §3 instructions still required the worker to write the gunbc_ci_yml_workflow binding — but there is no canonical CIWorkflowDag instance in main yet (PR #2736 introduces the carrier type, not an instance). The worker would have to either: (a) invent a placeholder CIWorkflowDag value inline in ci_emission.dag → parallel authority alongside the eventual Slice 4 canonical instance (P2 violation) (b) build CIWorkflowDag from CIPipeline via inline conversion → reopens Path (a) authority despite explicit rejection (P2) (c) leave the binding as a non-compiling forward-reference Fix: defer the pinned-projection binding to Slice 4. Slice 4 authors the canonical CIWorkflowDag instance AND the pinned-projection binding together; WI-2 scope shrinks to (1) EmissionTarget enum + receipt and (2) projection function signature. P2 single-authority restored because the only instance authority is the canonical Slice 4 source. c#3224878313 (line 64 anchor, Acceptance gates section): > "The WI-2 acceptance gate for the new substrate EmissionTarget sum > type omits the required 🟢/🟡/🔴 coproduct-dissolution > classification, so a worker could satisfy the brief while landing > [a parallel-taxonomy enum]." WI-1 brief (PR #2746 merged 08:29:09Z) carries Practice 4 receipt discipline for EmissionTarget at lines 115-141; WI-2 brief inherited the substrate-shape without inheriting the receipt requirement, creating a discipline asymmetry. A worker satisfying WI-2 could land EmissionTarget without the receipt, and the substrate would carry the same coproduct-dissolution debt the WI-1 canvas explicitly closes. Fix: add acceptance gate 3 requiring Practice 4 receipt (🟡 YELLOW classification + named dissolution trigger + coordinate-dissolution sketch) co-equal with the enum declaration itself.

Line 60 (code block): "// In dsl/gunbc/ci_emission.dag (NEW file, WI-2 lands it):" with the gunbc_ci_yml_workflow binding inside the code block. Fix: split the code block into (a) "WI-2 lands the signature" + (b) "Invocation pin DEFERRED to Slice 4" with the binding shown as a comment-block forward-reference. Cite WI-2 brief §3 + acceptance gate 5 as authority. 2. Line 149 (dependency graph parallelizable list): "WI-2 new file ... declares WorkflowRuntime open enum + project_github_actions function signature + gunbc_ci_yml_workflow pinned-projection". Fix: add Practice 4 receipt; mark gunbc_ci_yml_workflow as DEFERRED to Slice 4 with P2 rationale. 3. Line 173 (§6 WI-2 Output description): "Output: NEW file ... declaring WorkflowRuntime open enum + project_github_actions function signature + gunbc_ci_yml_workflow pinned-projection data binding". Fix: add Practice 4 receipt; mark binding as DEFERRED. 4. Line 206 (References list): "dsl/gunbc/ci_emission.dag — NEW file WI-2 creates (projection-function substrate; WorkflowRuntime enum + project_github_actions signature + pinned-projection binding)". Fix: add Practice 4 receipt; mark binding DEFERRED. All 4 sites now consistent with WI-2 brief §3 + acceptance gate 5 + DO/DON'T list + closure predicate (f830b98 + 011ddbc). Single P2-clean authority surface for the WI-2 scope across both the brief AND the scope doc. Lesson cascaded into discipline: when changing scope-of-deliverables semantic in ONE doc (the brief), grep ALL doc-of-record framing sites (brief + scope-doc) for the same claim. Closure-predicate fix in 011ddbc caught one cascade site; codex caught the scope-doc-side cascade gap that PM missed. Future PM-side check: after any §3 / acceptance-gate change in a worker brief, audit the parent scope doc for matching cascade.

Fix: defer PythonShim alongside InlineGunbc; initial enum becomes 2 arms (YamlStatic, BinaryShim). Sites updated: - WI-2 brief line 20-26 (enum block + initial-set claim), line 76 (DO list), line 97 (acceptance gate 2) - WI-1 brief line 31 (PythonShim DESIGN-ONLY treatment), line 61-62 (acceptance gates 2+3) - Scope doc line 18 (WorkflowRuntime toggle text), line 40 (workflow_runtime_open_enum_landed gate description), line 51-52 (code block + comments), line 104 (per-arm projection bodies) Symmetric DESIGN-ONLY treatment with InlineGunbc per Pure Bootstrap discipline: both land via separate substrate-prereq PRs paired with their concrete runtime consumers. * docs(briefs): WI-2 brief — fix Practice 4 dissolution sketch admits-impossible-states (briansrls BLOCKING on PR #2744 line 101 2026-05-12T10:46:59Z) Acceptance gate 3 said "the eventual factoring is `EmissionArtifactShape × ShimRunnerKind`" — but the Cartesian product admits impossible states like `(StaticYaml, CompiledBinary)` (you can't have StaticYaml WITH a runner; Static has no runner). Per INVARIANTS P2 illegal-states-unrepresentable discipline. WI-1 canvas §3 in main already uses the structurally correct factoring (sum-of-tagged-coordinates, not product): ``` type EmissionTarget = Static(EmissionArtifactShape) | Shim { runner: ShimRunnerKind } ``` Fix: update WI-2 brief acceptance gate 3 to cite the canvas factoring correctly. Receipt classification language also updated to note coordinates are NOT independent dimensions. * docs(scope): T-WAD — remove "absent" pass option from ci_yml_hand_authority_dissolved gate (openai-pro REQUEST_CHANGES on PR #2744 2026-05-12T10:51:06Z) Gate description at line 39 allowed "(a) absent (some workflow runtimes may not require a .github/workflows/ artifact)" but line 125 explicitly says "NOT file-deletion ... all require some .github/workflows/ci.yml artifact for GH Actions trigger discovery". Contradiction would let a worker satisfy the written gate by deleting the file while failing the corrected semantic intent. Fix: remove "absent" option from gate (both line 17 §0 framing + line 39 gate description). Initial enum (YamlStatic, BinaryShim) both REQUIRE the artifact. The "absent" option is structurally impossible — only conceivable for future DESIGN-ONLY runtimes (e.g., InlineGunbc) that don't target GH Actions, which would extend the gate at land-time via substrate-prereq PR. Also harmonized line 125 (Slice 8 note) to remove PythonShim mention (PythonShim demoted to DESIGN-ONLY in prior commit 338a83f). * docs(scope): T-WAD — clarify rename-paragraph variant-names listing per PythonShim DESIGN-ONLY status (openai-pro APPROVE_WITH_COMMENTS on PR #2744 2026-05-12T10:58Z) Line 34 (rename-context paragraph) listed "All OTHER ratified elements stand: variant names (YamlStatic | BinaryShim | PythonShim)" — but PythonShim is now DESIGN-ONLY per commit 338a83f (initial enum is 2 arms only). Even though the phrase is historical-context (rename-time ratified names), openai-pro flagged it as load-bearing enough to confuse downstream workers who scan the rename paragraph and might infer PythonShim is in the initial enum. Fix: clarify "initial-enum variant names (YamlStatic | BinaryShim); PythonShim is a reserved DESIGN-ONLY future name not in initial enum per INVARIANTS P5 — see §1 gate workflow_runtime_open_enum_landed". --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Content: - §1 affected-set lens Dimension enum reference (cite design doc §2) - §2 slow-test inventory grouped into 9 clusters (78 entries from scripts/slow-test-exemptions.txt) - §3 path-mapping skeleton table — (test_pattern, dimension, required_paths_regex, confidence, dissolution_note).

This conflicts with the locked design at `docs/design-affected-set-lens.md` §2: affected_set(Dag_before, Dag_after) = ⋃ over dim in {Value, Cost, Complexity, Effect, Refinement} affected_set(Dag_before, Dag_after, dim) A test that reads BOTH Cost AND Complexity (e.g., D-cluster LBP demonstration; lane2_stage_2f composed-matches-lens) would be silently skipped when only Complexity changes if its dimension is narrowed to "Cost." That's `INVARIANTS.md` P2 single-authority violation against the locked lens design. Fixes: - §1: rewrite from "exactly one primary dimension" to "dimensions is Set<Dimension> = full read-set; affectedness is union semantics" - Header bullet: hard constraint reframed — multi-dim REQUIRED when consumer reads multi; post-dissolution math is `(affected ∩ row.dimensions) ≠ ∅` - §3 table: column rename `dimension` → `dimensions`; rows updated: - D-cluster LBP, lens_cost_target_realization, cost_lens_consumer: expanded to multi-dim sets [Complexity, Cost], [Cost, Value] - lane2_stage_2f_dimension: [Complexity, Cost] (composed-matches-lens) - F-`m0_acceptance` + I-`thesis_validation_test`: full 5-dim set (compile-boundary + thesis-level read every dim) - G-`t_las_crdt_cost_basis_demo`: [Cost, Effect, Value] - G-`r3_free_consequences_second_batch`: [Cost, Value] - H-`t_ci_workflow_as_data_demo`: [Value, Cost] (DimensionReport timing) - All single-dim rows (A, B, Most-C, etc.): formatted as set `[Cost]` - §4 Open question 1: rewrite to forbid narrowing, mandate ADD-when-doubt - §5 acceptance: add dim-set-semantics + union-formula checks - §6 STOP triggers: add "tempted to narrow set → STOP and EXPAND" Director's Layer 2 brief at PR #2719 has the same singular-`dimension:` shape and likely has the same finding waiting to surface; will flag to Director after this lands.

A Mgr/worker following the brief literally would have wired the CI gate backward, silently skipping affected tests — TESTING.md "test selection must not skip affected behavior" violation + Boundary Discipline violation (boolean carrier name and contract encoded opposite meanings). **The bug**: 4 places stated post-dissolution `skip_<cluster>` formula as `(affected_dimensions ∩ group.dimensions) ≠ ∅` (skip when intersection NON-empty), while the CI consumer wires `if: skip_<cluster> != 'true'` (run when skip is NOT true). Combined: when intersection is non-empty (= affected), skip=true → tests don't run → affected tests silently skipped. **The fix**: invert the formula to `(intersection = ∅)` (skip when intersection IS empty = no affected dim that this cluster reads). The CI gate semantics stay the same; the polarity correction is on the post-dissolution lens mapping. Sites corrected: - §1 hard-constraint para (line 9): replaced "(non-empty intersection means run)" with an explicit Boolean polarity block defining `skip = (intersection = ∅)` and equivalent `run = (intersection ≠ ∅)` - §3 path-mapping intro (was line 132, now 142): same polarity fix + "Equivalently: `run = (intersection ≠ ∅)`" - §4 open-question 4 (was line 186, now 196): "skip_<cluster> becomes `(intersection ≠ ∅)`" → `(intersection = ∅)` with explicit "same polarity: skip when no affected dim" note - §5 acceptance (was line 206, now 216): same polarity fix + explicit "inverting the polarity silently skips affected tests" warning All 4 references now consistent. Polarity table: intersection = ∅ → skip=true → "do not run" (NOT affected, safe to skip) intersection ≠ ∅ → skip=false → "run" (affected, must run) Director's brief #2719 likely has the same polarity issue and will need parallel fix from the same authority chain.

Mechanism of the bug: - Markdown tables use `|` as column separator - To put a literal `|` IN a cell (outside backticks), you escape with `\|` - PM authored the regex with `\|` thinking the markdown-table escape was needed, but the regex is INSIDE backticks (code span) which preserves pipe character literally - A worker copying the regex into ci.yml would silently miss tokenize.dag changes (only matches literal `compiler|std/tokenize.dag`) Fix: drop the unnecessary `\` escape; markdown code spans preserve `|` literally.

Mitigation: the template's own validation discipline at §3 + §5 §6 (workers MUST validate regex against live source tree before CI implementation) would have caught this, but per openai-pro's read "the concrete row should still not carry a known-bad example" — fair.

My prior open-enum fix (c61a7ed) updated §1/§5/§6 to ALLOW user- defined dims but I didn't fix THIS row to USE one. Per the just- established 'carry the dim, don't narrow' framing in §6, this row should carry `[Value, Cost, Timing]` (or just `[Value, Timing]` if Cost is sufficiently distinct from Timing in the test). **Why it's load-bearing**: a future timing-only delta (e.g., DimensionReport schema change touching only timing fields, not Cost) would be 'affected' for this test under the lens but the prior row narrowed Timing → Cost → if Cost.affected = empty but Timing.affected non-empty, test would be silently skipped (TESTING.md violation + THESIS user-defined-dims framing violation). Fix: - Row dimensions: `[Value, Cost]` → `[Value, Cost, Timing]` - Row dissolution-note: explicit annotation citing `DimensionReport<TimingMeasurement>` + `ci_modeled_timing` user- defined dim + the carrying-vs-narrowing rationale - Self-references this template's own open-enum support per §1 — the row is now an in-table demonstration of the open-enum framing (consistency between framing and example) This also re-stress-tests cluster aggregation: cluster H aggregates over multiple rows including this Timing-carrying row, so cluster- level skip computation correctly fail-closes when ANY row's dim intersects with affected_dims.

Per the invariant I codified in §3 + §5 + §6, every concrete regex MUST include the OWN test-source arm under `src/v3/compiler/tests/integration/`. These rows didn't: 1. `dimension::analyze_complexity_tests::.*` — had `tests/integration/dimension.*\.rs` arm but that file doesn't exist (tests live inline as a module in `tests/integration.rs`); arm matched nothing → fail-open 2. `dimension::fail_closed_tests::.*` — NO test-source arm 3. `e7_analyze_complexity_integration::.*` — NO test-source arm 4. `lane2_stage_2f_dimension_test::.*` — NO test-source arm 5. `sg2c1_parse_tables_authority_test::.*` — NO test-source arm Fix: add test-source arm to each row: - For inline modules (dimension/e7/lane2_stage_2f): test lives inline in `src/v3/compiler/tests/integration.rs`; add that path. Broad-but- correct per fail-closed default (any edit to integration.rs triggers these tests; a finer-grained match isn't expressible via path regex because the modules are inline in the file). - For sg2c1 (standalone file): add explicit `src/v3/compiler/tests/integration/sg2c1_parse_tables_authority_test\.rs`. Each row's dissolution_note now carries inline annotation citing the codex BLOCKING finding + the test-source-arm correction rationale. **Lesson**: codifying the invariant in §3/§5/§6 doesn't retrofit existing rows — needed to AUDIT each concrete regex against the invariant after codification.

A Mgr/worker following the brief literally would have wired the CI gate backward, silently skipping affected tests — TESTING.md "test selection must not skip affected behavior" violation + Boundary Discipline violation (boolean carrier name and contract encoded opposite meanings). **The bug**: 4 places stated post-dissolution `skip_<cluster>` formula as `(affected_dimensions ∩ group.dimensions) ≠ ∅` (skip when intersection NON-empty), while the CI consumer wires `if: skip_<cluster> != 'true'` (run when skip is NOT true). Combined: when intersection is non-empty (= affected), skip=true → tests don't run → affected tests silently skipped. **The fix**: invert the formula to `(intersection = ∅)` (skip when intersection IS empty = no affected dim that this cluster reads). The CI gate semantics stay the same; the polarity correction is on the post-dissolution lens mapping.

Mechanism of the bug: - Markdown tables use `|` as column separator - To put a literal `|` IN a cell (outside backticks), you escape with `\|` - PM authored the regex with `\|` thinking the markdown-table escape was needed, but the regex is INSIDE backticks (code span) which preserves pipe character literally - A worker copying the regex into ci.yml would silently miss tokenize.dag changes (only matches literal `compiler|std/tokenize.dag`) Fix: drop the unnecessary `\` escape; markdown code spans preserve `|` literally. Now regex correctly reads `src/v3/(compiler|std)/tokenize.dag` — alternation between src/v3/compiler/tokenize.dag and src/v3/std/tokenize.dag, both of which exist per the source tree verified at 45fc195. Mitigation: the template's own validation discipline at §3 + §5 §6 (workers MUST validate regex against live source tree before CI implementation) would have caught this, but per openai-pro's read "the concrete row should still not carry a known-bad example" — fair.

Verification (codex was correct): - `docs/design-affected-set-lens.md` §2: `⋃ over dim in {value, cost, complexity, effect, refinement, ...}` (note ellipsis = open enum) - `THESIS.md` "User-defined dimensions" section: 'User-declared dimensions extend the same structural proof surface ... the ceiling of what gunbc can prove is user-extensible.' The built-in base set ≠ the full enum. My template was treating them as equivalent, which would have rejected valid user-defined dims at the STOP gate (INVARIANTS P1 single-authority violation against THESIS/design + P3 fail-closed violation since rejection-instead-of- fail-closed is the opposite of safety). Fixes: - **§1** Dimension enum reference: rewrote with explicit `Dimension = {value, cost, complexity, effect, refinement, ...}` notation + the trailing `...` annotated as "OPEN for user-defined" + paragraph on THESIS user-extensibility framing + explicit instruction to treat unknown dim as fail-closed (always-run), NOT reject - **§5** acceptance criterion: updated to reference the open enum + fail-closed-for-unknown behavior - **§6** STOP trigger: now reads "cannot be carried as a typed Dimension at all (e.g., string-as-dimension, runtime-only)" — that's the genuine structural failure.

My prior open-enum fix (c61a7ed) updated §1/§5/§6 to ALLOW user- defined dims but I didn't fix THIS row to USE one. Per the just- established 'carry the dim, don't narrow' framing in §6, this row should carry `[Value, Cost, Timing]` (or just `[Value, Timing]` if Cost is sufficiently distinct from Timing in the test). **Why it's load-bearing**: a future timing-only delta (e.g., DimensionReport schema change touching only timing fields, not Cost) would be 'affected' for this test under the lens but the prior row narrowed Timing → Cost → if Cost.affected = empty but Timing.affected non-empty, test would be silently skipped (TESTING.md violation + THESIS user-defined-dims framing violation). Fix: - Row dimensions: `[Value, Cost]` → `[Value, Cost, Timing]` - Row dissolution-note: explicit annotation citing `DimensionReport<TimingMeasurement>` + `ci_modeled_timing` user- defined dim + the carrying-vs-narrowing rationale - Self-references this template's own open-enum support per §1 — the row is now an in-table demonstration of the open-enum framing (consistency between framing and example) This also re-stress-tests cluster aggregation: cluster H aggregates over multiple rows including this Timing-carrying row, so cluster- level skip computation correctly fail-closes when ANY row's dim intersects with affected_dims.

Per the invariant I codified in §3 + §5 + §6, every concrete regex MUST include the OWN test-source arm under `src/v3/compiler/tests/integration/`. These rows didn't: 1. `dimension::analyze_complexity_tests::.*` — had `tests/integration/dimension.*\.rs` arm but that file doesn't exist (tests live inline as a module in `tests/integration.rs`); arm matched nothing → fail-open 2. `dimension::fail_closed_tests::.*` — NO test-source arm 3. `e7_analyze_complexity_integration::.*` — NO test-source arm 4. `lane2_stage_2f_dimension_test::.*` — NO test-source arm 5. `sg2c1_parse_tables_authority_test::.*` — NO test-source arm Fix: add test-source arm to each row: - For inline modules (dimension/e7/lane2_stage_2f): test lives inline in `src/v3/compiler/tests/integration.rs`; add that path. Broad-but- correct per fail-closed default (any edit to integration.rs triggers these tests; a finer-grained match isn't expressible via path regex because the modules are inline in the file). - For sg2c1 (standalone file): add explicit `src/v3/compiler/tests/integration/sg2c1_parse_tables_authority_test\.rs`. Each row's dissolution_note now carries inline annotation citing the codex BLOCKING finding + the test-source-arm correction rationale. **Lesson**: codifying the invariant in §3/§5/§6 doesn't retrofit existing rows — needed to AUDIT each concrete regex against the invariant after codification. PM did partial audit on path correctness (dsl/std → src/v3/lenses) but didn't re-audit for test-source-arm presence. cursor #9858 noted earlier the boxed-formula inconsistency in §1; codex now caught the same class on §3 row content.

Fix-forward: introduce `type NonZeroRational = Rational where nonzero` at the type-alias layer (alongside existing `PolyLogExponent = Rational where gt_one` + `ExponentialBase = Int where range(min: 2)`). PolynomialCost.degree field type references the named alias: `degree: NonZeroRational`. Updates across both briefs: - All `degree: Rational where nonzero` → `degree: NonZeroRational` (5 canvas occurrences + 10 worker occurrences) - Worker §5.0 dag block: NonZeroRational alias declaration added with rationale comment citing codex worker:167 + HEAD parser constraint - Canvas §6 refinement-carriers list: NonZeroRational row added with named-alias note - Worker §5.0 HARD STOP directive: NonZeroRational added to the hard-stop list (named alias, not fresh record); HEAD parser constraint cited - Worker §10 STOP #4 variant-collision list: NonZeroRational added - Worker §5.0 P1/P2 narrative: clarified "DOES carry NonZeroRational named-alias" framing - Worker §7 bootstrap ratchet test: type-rejection test asserts both the type-alias declaration AND the degree=0 rejection at carrier level - Worker §13 verification axis: NonZeroRational added to refinement- carriers test list INVARIANTS P2 + Practice 2 carrier-level illegal-states-unrepresentable satisfied via named alias (P5 / parser-supported substrate syntax). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 canvas — fix §6 'no refinement' stale text (codex canvas:218) Canvas §6 closing paragraph still said "PolynomialCost.degree intentionally has no refinement" — pre-msg_b80bcaa8 framing that contradicts the NonZeroRational alias declared 3 lines above + ratified by msg_b80bcaa8. Fix-forward: reframe as "no positivity refinement, but DOES carry NonZeroRational named alias for zero-exclusion". Sign-admission preserved (msg_2c1bfb0e); zero-exclusion enforced (msg_b80bcaa8). Also added explicit reference to degree=0 alongside exponent≤1 / base≤1 in the structurally-unrepresentable set.

Canvas STOP-SIGNAL aligned to msg_d86a5987 for single-authority trace. INVARIANTS P2 single authoritative trace restored.
