Authors the T-Ground-LanguageSpec brief (lane 6 of 11 in R2 Grounding Manager's program) ahead of PR-I dispatch gate. Consumes Tier 1 locks (Q1 / reflection-completeness / Q6.5) live on main; queues option-(c) slice-1 re-home, MethodContract consolidation, and Reflective Pattern E mirror retirement.

Manager review (silent-ant-322 — R2 Grounding Manager): APPROVED to mark ready-for-review. Spot-checked citations: Scope reads correctly per the engine-reframe spec:
Two minor nits (non-blocking; address in same PR if cheap):
Mark ready-for-review when convenient. I'll route to Director on merge for cross-program awareness (MethodContract consolidation may carry a Substrate signal). |
Per silent-ant-322 review on #1168: - Test plan item 4: name post-D end state (structural LanguageSpec walk only; StructureMismatch retained as substrate-load-time integrity check, not mirror parity). - Cross-refs: note pre-cascade sibling lanes will be superseded by post-cascade lane briefs once authored.

Verdict: APPROVE — This change only adds Findings: None that tie a diff line to a stated invariant/testing/coding rule. Exploratory (optional): At |
MethodContract type-shape is Substrate-owned (jolly-ram-908 #1130); this lane consumes the type and owns row population + drift resolution + parallel-rep × 3 retirement. Adds dependency-table row for the cross-manager request, splits P1 receipts (type → Substrate PR; row coordinates + PlaceholderConvention instances → this lane), and fences the type declaration as out-of-scope.

BLOCKING (3)
Root Cause
docs/briefs/t-ground-languagespec.mdAuthority inventory was copied from in-flight or absent docs without verifying repo paths → land the authority docs in this PR or rewrite the brief to checked-in THESIS/INVARIANTS/ROADMAP anchors.docs/briefs/t-ground-languagespec.mdThe DAG-ancestor check was deferred instead of performed while authoring the brief → inventory existingLanguageSpecdeclarations and make the lane operate on one named authority.docs/briefs/t-ground-languagespec.mdThe method-contract inventory checked the runtime files and Rust emit file but not all target emit files → enumerate every{runtime,emit}method authority per target and update the dissolution scope.

BLOCKING: The locked engine-reframe authority link resolves to no checked-in file, so the brief is not reviewable as live documentation and violates its own drift-stop discipline.
| - **External-realization shape** — `Arrow.body` per E-9. | ||
| - **Per-primitive `RealizationCost`** — see B below. | ||
|
|
||
| **Canonical home (P1-Step-1 DAG-ancestor check):** the brief proposes `src/v3/std/language_spec.dag` (or, if a closer ancestor surfaces during authoring, attach via inhabitance rather than declare a sibling). Worker MUST run the P1 procedure (`INVARIANTS.md:86-123`) and cite which steps resolved the location, *before* declaring the type. If Step 1 surfaces an existing parent (e.g., a target-spec carrier already in `dsl/extdeps/languages/`), re-home there and cite — escalate if no parent fits and you are tempted to declare a fifth bound-style sibling (see Q1 receipt at `design-emission-model.md:1019-1029` for the worked dissolution pattern). |

BLOCKING: This makes a new src/v3/std/language_spec.dag the default canonical home even though src/v3/std/emit_model.dag already declares LanguageSpec, creating duplicate substrate authority unless the brief names the existing type as the target and specifies move/extension/deletion.

| For every case that previously looked like "multiple inhabitants needing canonical," re-audit per Modeling problem 2 corrected: is the difference cosmetic (collapse) or meaningful (model the structural axis)? | ||

BLOCKING: Python and Go emit method authorities are python_method_templates and go_method_templates maps, not SimpleMethodSpec declarations, so this retirement instruction leaves parallel emit-side method representations alive and violates Single Authority.

Cursor review on #1168 caught: SimpleMethodSpec is Rust-only (dsl/extdeps/languages/rust/emit.dag:47); Python and Go use python_method_templates / go_method_templates Map<String, String> (emit.dag:87 / :83). Brief originally wrote "MethodTranslation + SimpleMethodSpec × 3" — incorrect. Verified per-target authority landscape and replaces the count-of-3 framing with an explicit table.

…2 target (#1172) * docs(briefs): name existing LanguageSpec target — emit_model.dag:302 Cursor review on #1168 caught parallel-authority risk: brief proposed src/v3/std/language_spec.dag as canonical home, but LanguageSpec is already declared at src/v3/std/emit_model.dag:302 (and a second time at dsl/std/languages.dag:438 — pre-existing parallel-authority debt). Fix: reframe Section A as EXTENDS the existing emit_model.dag type; new file only authored if the existing shape provably can't host the engine-reframe additions (escalates to manager first). Names the dsl/std/languages.dag duplicate as a dissolution target; drift between the two shapes resolves explicitly in the lane PR. Adds parallel-authority retirement to dissolution claim.

…calibration (5→11 sub-lanes) + §4 sub-item 6 + sequencing discipline
Director R2-Grounding audit (msg_8ae92369 2026-05-13) absorbed. Critical first-order finding: PM originally cited 5 T-Ground sub-lanes in Gap 13 framing; actual ledger count is **11 sub-lanes** per docs/r2-closure-ledger.md:108 ("11 lanes per engine-reframe") + docs/briefs/r2-grounding-manager.md:168 ("now 11 lanes; engine-reframe locked 2026-04-28"). PM-side under-counted the residual surface by ~half.
11-sub-lane recalibration:
- GREEN (1 of 11): T-Ground-Pilot (PR #765 merged 2026-04-25)
- IN-FLIGHT (7 of 11): T-Ground-Rust / Python / Go / LanguageSpec / Coercion-Fold / Lifetime-Analyzer / CrossTarget-Meta — each cites era-#1168-#1241 PRs + R3-tier slice landings; HEAD-state likely partial-cashed
- NOT-STARTED (3 of 11): T-Ground-Diagnostic / T-Ground-Tests / T-Ground-Dissolve (brief-only at R2-close)
Director estimation: 3-5 of 11 effectively GREEN at HEAD; 4-6 in-flight; 3 not-started. Full per-sub-lane HEAD audit needed (analogous to neat-heron-793 R2-Evaluator ledger refresh).
Director audit (b)/(c)/(d) findings:
- (b) NO R3 Grounding Mgr session in current subtree; authority partially dispersed under warm-wolf-698 Substrate Mgr organically (PR #1980 Coercion-Fold retirement + PR #2103 L6 + PR #2272 u128 + PR #2279 SelectedTargetInhabitance + PR #2229 cost_target_realization). Same anti-pattern as merry-gull-128 absence.
- (c) Brief coverage COMPREHENSIVE — even stronger than R2-Evaluator (8 dedicated T-Ground briefs + 9+ R3-tier slice briefs).
- (d) Director recommends OPTION (α) re-spawn R3 Grounding Mgr as 5th R3 Mgr lane (post-Evaluator re-spawn making 4), with critical scope-discrimination caveat: Mgr-tier brief authoring must discriminate Grounding-owned scope vs Substrate-Mgr-already-absorbed scope (warm-wolf-698 organic absorption).
Director sequencing discipline (Note 2 + Note 3 carried forward from msg_f0a54769):
- Close criterion = substrate-debt-only (11 sub-lanes status=green per r2-closure-ledger refresh + emit_model.dag SCAFFOLD dissolution + coercion.dag schema dissolution + emit.rs retirement + §1.8 row)
- Dispatch staffing prereq SEPARATE from close criterion (sub-item 6 ratification ≠ substrate-debt satisfaction)
- Sequencing: re-spawn AFTER operator §4 sub-item 6 ratification, NOT before
§4 sub-item 6 added: R3 Grounding Mgr dispatch shape — (α) re-spawn 5th R3 Mgr lane (PM + Director recommended with scope-discrimination canvas as first deliverable) / (β) fold into warm-wolf-698 Substrate Mgr (named scope-bloat risk: substantial dual-program lane shape; warm-wolf-698 already carries 9-worker Phase B batch + Cluster M Phase 3 coordination + canvas authoring) / (γ) Director-direct ad-hoc (PM does NOT recommend per r2-structure.md:73 anti-pattern).
Bundling: per Director recommendation, §4 sub-item 5 (Evaluator) + sub-item 6 (Grounding) need same dashboard-tier intervention (composite-shape support per operator escalation msg_acf78d37 in flight). Recommend bundling both into one operator-ratification batch — dashboard-tier intervention unblocks both lanes simultaneously.
Effort estimate revised: 6-12 weeks → 8-16 weeks (11 sub-lanes vs originally 5; scope-discrimination canvas added).
§6 checklist updated: Gap 13 entry refreshed with 11-sub-lane scope + audit completion; §4 sub-item 6 added as new checkbox bundled with sub-item 5.

…coercion-engine architectural separation (#3038) * docs(r3): fix interrogation-doc JS/TS scope drift + add Gap 11 (LogCost asymmetry / complexity composition completeness) Operator adversarial probe 2026-05-13 surfaced two issues: 1. docs/r3-close-interrogation.md §285 + §291 cited "Rust + JavaScript + Python (3 R3 Shape-A targets per §3.1)" — drift relative to §518 of same doc which correctly enumerates "R3 = 3 Shape-A targets: Rust / Python / Go". The JavaScript framing was operator-illustrative example pre-dating R3 scope finalization that authored into normative scope text. Fix: §285 scope claim corrected to "Rust + Python + Go"; JavaScript references in bug-shape examples preserved as illustrative-not-scope with explicit clarifying note pointing to §518 authority. §291 cross-target-test-claim bullet expanded to include "Go via go test" alongside the illustrative JavaScript/jest reference. 2. Operator probe: "regarding complexity - what about more complex combinations of complexity - i.e. n log (n^k) i.e. nested algorithms - do we handle all permutations of those?" + "regarding logcost - my concern is that this seems orthogonal to logcost - shouldn't it work for any arbitrary combination of cost?" HEAD audit: SymbolicCost in src/v3/std/algebra.dag has structural asymmetry — ProductCost + SumCost are recursive over arbitrary SymbolicCost; LogCost + PolynomialCost take only SizeVariable (terminal). Cannot construct Log(complex) directly. normalize() body handles sum/product identities + LinearCost-squared → PolynomialCost, but NO log-power rule (log(n^k) → k log(n)), NO log-product rule, NO nested-log handling. AsymptoticClass enumerated lattice ceilings on polynomial×log composition (loses log factor on classification). Fix: Gap 11 added to close plan §1 — Complexity composition completeness / LogCost asymmetry. Sub-promise of gate #79 complexity behavioral close that the 2026-05-13 adversarial sweep missed. Owner: Substrate Mgr (warm-wolf-698). Substrate-shape canvas decision required: (A) LogCost recursive over SymbolicCost (symmetric with Product/Sum) OR (B) dag-authored canonicalization rule that runs before LogCost construction with named log-algebra coverage. Close criterion: shape ratified + normalize/canonicalization landed + lattice tier review + cementing corpus extended with nested compositions (n log n^k, n² log n, n log² n, log log n). Plan §2 sequencing updated to include Gap 11 in Phase B (Substrate Mgr lane). §6 checklist updated with the post-§4-ratification adversarial finding status. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): add Gap 12 (property-based complexity-lens validation via ProgramGenerator) per operator adversarial probe 2026-05-13 Operator follow-up probe 2026-05-13: "for complexity - do we have testcases representing random combinations of functions, validating that the correct complexity result is generated? please add that" HEAD audit: - `ProgramGenerator` substrate carrier LANDED (gate #86; `src/v3/std/verification.dag`) but only used in `m1_5_verification_test.rs::program_generator_authoring_surface_compiles_cleanly` (compile-surface verification, NOT actual random-program generation) - `ForAll` quantifier in `verification.dag` is wired only for `ForAllTargets` (cross-target per Gap 2), NOT for `ForAll(random_program)` quantification - Complexity cementing test at `src/v3/compiler/tests/integration/cementing/complexity_lens_behavioral_completion.rs`: only 2 hand-authored cases (`literal_bind_cements_constant_complexity_summary` + `recursive_countdown_cements_linear_work_and_span`) - Zero `proptest` / `quickcheck` / random-composition tests against the complexity lens Result: gate #79 `lens_capability_register_zero_proxy_zero_stub` lens-completion can claim "behaviorally complete" while never having validated against arbitrary nested compositions — the substrate's SymbolicCost composition class is enormous vs the 2 cementing cases. Fix: Gap 12 added — Property-based complexity-lens validation via ProgramGenerator. Owner: Verification Mgr (still-moth-538). Substrate Mgr (warm-wolf-698) co-owns the ProgramGenerator-instance + oracle authoring. Sub-program: (1) ProgramGenerator complexity-instance producing structurally-bounded random function compositions; (2) complexity oracle (`.dag`-authored function from generated-program → expected ComplexitySummary; NO bridge-Rust oracle per feedback_no_textual_enforcement_bridges); (3) `ForAll<ProgramGenerator>` quantifier extension (currently only ForAllTargets); (4) property-based TestClaim asserting complexity_of(g) == oracle(g) for N≥100 samples per CI run; (5) CI integration with seed-pinning + reproducibility discipline. Close criterion: (a) ProgramGenerator complexity-instance landed; (b) `.dag`-authored oracle landed; (c) ForAll<ProgramGenerator> TestClaim landed + passing with N≥100; (d) zero oracle-vs-lens divergence; (e) CI seed-pinning ratcheted. Effort estimate: 2-3 weeks, parallelizable with Gap 11 substrate-shape canvas authoring. Gap 12 generator depends on Gap 11 substrate decision so generator can produce the full composition class. §2 sequencing updated: Gap 12 in Phase C (Verification Mgr lane); §6 checklist tracks Gap 12 as post-§4-ratification adversarial finding. Document order in §1 corrected to Gap 11 → Gap 12 (matching gap-number sequence). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address briansrls BLOCKING on PR #3037 — recalibrate Gap 11 HEAD evidence + rewrite §285 probes to R3 targets Two BLOCKING findings from operator briansrls comment-4445313478 at 2026-05-13T21:04:54Z: B1 (docs/r3-actual-close-plan.md Gap 11): operator-probe notes were promoted to HEAD evidence without verifying actual classifier behavior in src/v3/std/algebra.dag + src/v3/compiler/src/dag_cost_generated.rs. Verified HEAD evidence (revised): - `classify_symbolic_cost` at dag_cost_generated.rs:289-312 maps ALL composite costs (ProductCost / SumCost) to `ClassUnknown` — no composition handling. Prior framing "lattice ceilings to ClassPolynomial" / "collapses to ClassLinearithmic" was wrong; actual behavior is collapse to ClassUnknown for any composition. - `ClassLinearithmic` + `ClassExponential` are unreachable outputs from the classifier — only constructible via string-to-AsymptoticClass deserialization at enforced_lens_application.rs:960-962 for user-declared enforcement budgets. 2 of 8 lattice tiers are write-only. - SymbolicCost substrate has no `ExponentialCost` variant; `2^n` cannot be represented in source cost. ClassExponential is the lattice analog but unreachable from any SymbolicCost expression. - normalize() at algebra.dag:537-548 handles only sum/product identity rules + LinearCost-squared → PolynomialCost(degree=2). No log-rule simplification, no Product/Sum→named-tier normalization. Recalibrated Gap 11 "What's missing" — 6 items (was 4): (1) classify_symbolic_cost composition arms (root issue — even n log n classifies to Unknown), (2) LogCost recursive shape OR canonicalization rule, (3) ExponentialCost variant decision, (4) ClassLinearithmic/Exponential reachability gap, (5) normalize log-rule extensions, (6) cost-lens fold audit. Recalibrated close criterion — 7 items (was 5), adding (a) classifier produces all reachable tiers including ClassLinearithmic for n log n, (c) ExponentialCost ratified-or-excluded, (e) AsymptoticClass reachability review complete with formal annotation of input-only tiers. Effort estimate revised up from 2-4 weeks to 3-5 weeks per recalibrated sub-program scope. B2 (docs/r3-close-interrogation.md §285+§291+§295+§297+§312): the prior fix added a "JavaScript references are illustrative-not-scope" disclaimer but left the gating probes themselves using JavaScript examples. Per operator: "convert the concrete R3 probes to Rust/Python/Go". Rewrote 5 gating probes + introduction + 2 falsification probes + 1 R3-close-audit-for-class line to use Rust/Go/Python concretely: - Cross-target serialization round-trip: Rust → Go (not JS) - Cross-target numeric width: Rust u32 vs Go uint32 vs Python arbitrary-precision int (not JS 53-bit) - Cross-target effect divergence: Rust tokio vs Go goroutines+channels vs Python asyncio (not JS Promise) - Cross-target boundary trust: Rust ↔ Go gRPC/HTTP/FFI (not Rust ↔ JS FFI/WASM) - Cross-target test-claim transferability: cargo test / pytest / go test (removed JS jest) - Modeling-level cross-target gap: Go's nil-interface-vs-nil-concrete-type (not JS prototype-pollution) - R3 close audit demo: Rust server + Go client (not JS client) - Introduction text: "Rust ↔ Go ↔ Python via shared .dag substrate" (was Rust ↔ JavaScript ↔ Python) Disclaimer language removed — probes are now R3-scope-correct without needing a disclaimer. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3-close): fix Gap 11 PolynomialCost field-type + line-cite per cursor APPROVE_WITH_COMMENTS PR #3037 Cursor BLOCKING (sha 412a8cb, 2026-05-13T21:16Z) — 2 substantive findings on Gap 11 HEAD evidence: F1 (line 383, INVARIANTS P1 modeling-faithfulness): PolynomialCost field cited as `degree: Nat` but actual substrate at `src/v3/std/algebra.dag:193` is `degree: DegreeAtLeastTwo` (refinement type, NOT raw Nat). The refinement encodes substrate-level guarantee that polynomial degree ≥ 2 (degree 1 redundant with LinearCost; degree 0 redundant with ConstantCost). Load-bearing for ClassPolynomial classifier arm at `dag_cost_generated.rs:297-306` and string-arm decoding in `enforced_lens_application.rs`. F2 (line 380, minor lens): cite "lines 190-196 (7 variants)" misaligns with substrate — line 190 is the `type SymbolicCost inhabits Semiring<SymbolicCost>` declaration; variant arms span lines 191-197 (7 arms). Corrected cite. Fix: updated PolynomialCost row to `degree: DegreeAtLeastTwo` with named rationale + load-bearing-citation; corrected line-cite to "lines 191-197, 7 variant arms; inhabits Semiring<SymbolicCost> declaration at line 190". Cursor exploratory note acknowledged: confirms Gap 11 evidence is otherwise correct (`ProductCost / SumCost → ClassUnknown` at dag_cost_generated.rs:308-310; `ClassLinearithmic` / `ClassExponential` string arms at enforced_lens_application.rs:960-962) — the PolynomialCost field-type was the only substantive slip.

Gap 13 is analogous R2-residual to Gap 3 (R2-Evaluator); both surfaced post-§4 — R2-Evaluator via Director audit, R2-Grounding via operator adversarial probe.

Director audit (b)/(c)/(d) findings: - (b) NO R3 Grounding Mgr session in current subtree; authority partially dispersed under warm-wolf-698 Substrate Mgr organically (PR #1980 Coercion-Fold retirement + PR #2103 L6 + PR #2272 u128 + PR #2279 SelectedTargetInhabitance + PR #2229 cost_target_realization). Same anti-pattern as merry-gull-128 absence. - (c) Brief coverage COMPREHENSIVE — even stronger than R2-Evaluator (8 dedicated T-Ground briefs + 9+ R3-tier slice briefs). - (d) Director recommends OPTION (α) re-spawn R3 Grounding Mgr as 5th R3 Mgr lane (post-Evaluator re-spawn making 4), with critical scope-discrimination caveat: Mgr-tier brief authoring must discriminate Grounding-owned scope vs Substrate-Mgr-already-absorbed scope (warm-wolf-698 organic absorption). Director sequencing discipline (Note 2 + Note 3 carried forward from msg_f0a54769): - Close criterion = substrate-debt-only (11 sub-lanes status=green per r2-closure-ledger refresh + emit_model.dag SCAFFOLD dissolution + coercion.dag schema dissolution + emit.rs retirement + §1.8 row) - Dispatch staffing prereq SEPARATE from close criterion (sub-item 6 ratification ≠ substrate-debt satisfaction) - Sequencing: re-spawn AFTER operator §4 sub-item 6 ratification, NOT before §4 sub-item 6 added: R3 Grounding Mgr dispatch shape — (α) re-spawn 5th R3 Mgr lane (PM + Director recommended with scope-discrimination canvas as first deliverable) / (β) fold into warm-wolf-698 Substrate Mgr (named scope-bloat risk: substantial dual-program lane shape; warm-wolf-698 already carries 9-worker Phase B batch + Cluster M Phase 3 coordination + canvas authoring) / (γ) Director-direct ad-hoc (PM does NOT recommend per r2-structure.md:73 anti-pattern). Bundling: per Director recommendation, §4 sub-item 5 (Evaluator) + sub-item 6 (Grounding) need same dashboard-tier intervention (composite-shape support per operator escalation msg_acf78d37 in flight). Recommend bundling both into one operator-ratification batch — dashboard-tier intervention unblocks both lanes simultaneously. Effort estimate revised: 6-12 weeks → 8-16 weeks (11 sub-lanes vs originally 5; scope-discrimination canvas added). §6 checklist updated: Gap 13 entry refreshed with 11-sub-lane scope + audit completion; §4 sub-item 6 added as new checkbox bundled with sub-item 5.

Ask 4 — Cursor-composer-2 parser fix: (a) fix-dispatch authorized (class-level unblock for PR #3014/#3025/#3036/#3037) 5. Ask 5 — PR #3036 + PR #3025 merge-bypass: Director squash-merge both authorized (precondition (2) of feedback_operator_tier_merge_bypass_precedent cashed) §6 checklist updates: §4 sub-item 6 marked [x] RATIFIED with execution shape; Gap 13 marked [x] with ratification context; previous Gap 13 entry recalibrated 5→11 sub-lanes per Director audit msg_8ae92369 preserved as audit trail. §4 header: ratification outcomes split into two batches — "Initial ratification batch (PR #3013 merge)" covering items 1-5 + Phase A authorization; "Bundled-5-asks ratification batch (PR #3038 routing)" covering item 6 + dashboard-tier intervention + parser fix + bypass-merge directive. §4 sub-item 6 preamble updated: now reads "RATIFIED (α) re-spawn by operator briansrls 2026-05-13 via bundled-5-asks PM-routing — see Ratification outcomes above". Pattern parallels sub-item 5 ratification framing. §5 process discipline note updated: removed "meta-blocked" framing for Gap 3 + Gap 13 close-criteria (both sub-items 5 + 6 ratified; meta-block resolved); substrate-debt execution proceeds per ratified Mgr-lane dispatch shape (Director executes re-spawn post `--shape` flag landing per Ask 1).

"5 R2-T-Ground sub-lane status verification" — STALE; Director audit msg_8ae92369 recalibrated count to 11 sub-lanes (1 GREEN + 7 in-flight + 3 not-started); body at lines 505 + 564 already reflects 11 2. "Substrate Mgr executes sub-lane closures" — STALE; pre-assigned execution to Substrate Mgr before operator §4 sub-item 6 ratification. Operator ratified (α) re-spawn R3 Grounding Mgr (5th R3 Mgr lane) at 2026-05-13 via bundled-5-asks PM-routing; Grounding Mgr executes, NOT Substrate Mgr openai-pro finding: "the stale Gap 13 Phase E line is load-bearing planning text" — a worker following Phase E could audit 5 lanes and stop while the close criterion requires 11, AND would route execution to Substrate Mgr instead of the ratified R3 Grounding Mgr lane. Fix at line 617: - "5 R2-T-Ground sub-lane status verification" → "11 R2-T-Ground sub-lanes" with explicit recalibration note + feedback_full_predicate_over_categorized_grep_in_scope_statements citation - "Substrate Mgr executes sub-lane closures" → "R3 Grounding Mgr (5th R3 Mgr lane, re-spawn (α) RATIFIED by operator 2026-05-13 per §4 sub-item 6) executes the 11 sub-lane closures + scope-discrimination canvas as Mgr-tier first-deliverable" - Added: execution gated on --shape flag landing per §4 sub-item 1 ratification Now consistent with Gap 13 body (lines 505 + 564 + 736) + §4 sub-item 6 ratification state + Director audit findings (b)/(d). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3-close): retarget Gap 12 to existing QuantifiedTestClaim authority + runner wiring per briansrls BLOCKING on PR #3038 line 463 briansrls BLOCKING comment-... 2026-05-13T22:42:32Z on docs/r3-actual-close-plan.md:463 (INVARIANTS P2 single authority / documentation describes live state) — Gap 12 framing pointed workers at wrong authority. PRIOR (WRONG) FRAMING: "ForAll quantifier in verification.dag is wired only for ForAllTargets ... NOT for ForAll(random_program) quantification". Plan said workers should "extend ForAll quantifier surface from ForAllTargets to ForAll<ProgramGenerator>". VERIFIED HEAD EVIDENCE (correcting the framing): - `type Quantifier = ForAll | Exists` at src/v3/std/verification.dag — claim-layer quantifier for property-based testing; SEPARATE from ForAllTargets (which is the cross-target quantifier on different axis per Gap 2) - `type QuantifiedTestClaim { name, generator: ProgramGenerator, quantifier: Quantifier, predicate: TestPredicate, requires: List<ResourceReference> }` at src/v3/std/verification.dag:542 — the EXISTING single-authority for ForAll<ProgramGenerator> property-based claims - Suite integration LANDED: `type SuiteClaim = Enumerated(TestClaim) | Quantified(QuantifiedTestClaim)` at :594 - TestNode integration LANDED: `type TestNodeRef = EnumeratedTestNode(TestClaim) | QuantifiedTestNode(QuantifiedTestClaim)` at :574 - Obligation projection LANDED: `obligation_for_quantified_claim` at :627 - Test fixture LANDED: `data smoke_quantified_claim: QuantifiedTestClaim = { ... }` at test_runner_test.rs:1247 - Runner is `NotYetImplemented` at test_runner.rs:2511 with named gate #85 dissolution trigger via Cluster M Phase 2/3 Per the existing substrate, INVARIANTS P2 single-authority is structurally complete at the substrate level. The gap is the RUNNER, not the substrate. CORRECTED FRAMING: Gap 12 now targets (1) wiring the existing QuantifiedTestClaim runner per gate #85 dissolution trigger, (2) authoring complexity-specific ProgramGenerator instance + oracle, (3) authoring property-based QuantifiedTestClaim data declarations against existing substrate. NOT extending ForAllTargets. Sub-program restructured: - Step 1 (NEW): audit QuantifiedTestClaim shape sufficiency per feedback_construction_over_ratchets (model first; extend only if needed) - Step 5 (NEW): wire the runner at test_runner.rs:2511 (replace NotYetImplemented per gate #85 dissolution trigger — Cluster M Phase 2/3 lane scope per inline cite) - Removed step "extend ForAll quantifier surface from ForAllTargets" (was wrong authority) Close criterion adds (d): runner wired at test_runner.rs:2511 with N≥100 sample evaluation; removes prior "ForAll<ProgramGenerator> extension" framing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3-close): fix stale Gap 13 dispatch-prereq blocker state — operator already ratified per briansrls openai-pro BLOCKING PR #3038 briansrls openai-pro REQUEST_CHANGES (manual-trigger sha 38fd26a 22:57Z) — line 591 stale relative to ratification state: Finding (INVARIANTS P2 single-authority / top-down PM intent review): line 591 said "PM-recommendation Option (α) is on-record but execution waits on operator" — CONTRADICTS line 671 (§4 sub-item 6 RATIFIED) + line 722 (§5 process-discipline note: both sub-items ratified + execution proceeds after --shape lands). Worker following Gap 13 section could stall the lane incorrectly. Root cause: I authored the Dispatch staffing prereq paragraph BEFORE operator §4 sub-item 6 ratification landed (commit 962ce5d). When I recorded ratification at commit 198a752, I updated §4 + §6 checklist but didn't update this prereq paragraph. Stale pre-ratification framing survived. Fix: rewrote Dispatch staffing prereq paragraph to reflect post-ratification state: - "RATIFIED 2026-05-13 per §4 sub-item 6: (α) re-spawn as 5th R3 Mgr lane confirmed" - Sequencing now says "re-spawn occurs AFTER --shape flag landing per §4 Ask 1 ratification" (NOT "AFTER operator §4 sub-item 6 confirmation") - Cites Director dispatched --shape flag worker adhoc-745d73fa-6c4 per msg_14c3ad9d - Explicit: "execution is now gated on dashboard-tier --shape flag availability, NOT on operator confirmation (which is already in place)" PR #3038 was ready=True (2 distinct approvals codex + cursor on 38fd26a; 0 active reviews; mergeable=MERGEABLE; checks=passing) when briansrls manual-triggered openai-pro found this stale line.
