Pushing to session/keen-otter-117 advances this PR.

Summary

Wire §1.8 gate #10 `l7_algebraic_laws_witnessed` as an executable consumer: rename the L7 matrix lead row to the canonical `TestClaim.name` / declaration id, document slice vs §Acceptance closure in the fixture, add `l7_algebraic_laws_witnessed_passes_bounded_associativity_witness`, and promote gate #10 to CONSUMER_LANDED in `docs/r3-program-plan.md` while keeping PASSING tied to exhaustive `r3-structure.md` coverage.

INVARIANTS §P5 (b) — expanded `src/v3/**` Rust

Checkable receipt for this PR: integration-only Rust edit — `src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs` (new bounded-witness test + matrix allowlist uses canonical gate decl id). No edits to `src/v3/compiler/src/**` production code. No `sg0_census_test.rs` / SG-0 hand-path delta.

Test plan

• Remote: `cargo test -p v3-compiler r3_verification_l4_l7_l5_skeleton_test` — pass (10 tests, incl. new gate witness).
• CI on this PR: `fmt`, `ci`, `v3` jobs — green at last poll (`mergeable_state: clean`, check rollup SUCCESS).

Verification (composer-2 dashboard review @ 2026-05-10)

Cross-checked current `main`-aligned branch:

• Ledger separation: `docs/r3-program-plan.md` gate row Design: Diff Gist Mode for Branch Change Snapshots #10 stays CONSUMER_LANDED vs PASSING (exhaustive §Acceptance called out in Notes); lane summary table row for T-V-L4-L7-Direct matches.
• Canonical gate hook: `src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag` declares `data l7_algebraic_laws_witnessed` with `TestClaim.name` matching §1.8 gate id; matrix suite lists it as the lead row; comments still flag slice vs exhaustive closure.
• Integration: `l7_algebraic_laws_witnessed_passes_bounded_associativity_witness` resolves the declaration by id, asserts `claim_name`, and expects `Pass` — consistent with gate Remove LLM response caching module #9–style harness.

P5 PR-body hygiene: Agreed it was outside the diff; updated this PR description with an explicit §P5(b) receipt (integration-only `src/v3/**` Rust scope, no SG-0 delta).

Merge readiness: Required CI (`fmt`, `ci`, `v3`) is green and `mergeable_state` reports clean. GitHub `reviewDecision` / `latestReviews` still show no submitted PR reviews in the API, so the ≥2 distinct approving providers bar from merge policy is not met here yet — not squash-merging until those land (no `REQUEST_CHANGES` observed).

[Director conformance check — fallback for missing dashboard provider reviews]

Note: GitHub blocks self-approval; recording Director read for Mgr/operator visibility.

Verdict: would-approve. Substantive §1.8 gate #10 promotion DECLARED → CONSUMER_LANDED (+46/-13, 3 files).

What it does: Wires gate #10 (l7_algebraic_laws_witnessed) as an executable consumer:

1. Renames matrix lead row r3_l7_semigroup_associativity → canonical l7_algebraic_laws_witnessed (matches §1.8 gate identifier)
2. Updates L7_MATRIX_PASS_CLAIMS allowlist + matrix suite reference to canonical name
3. Adds new integration test l7_algebraic_laws_witnessed_passes_bounded_associativity_witness as explicit gate consumer
4. Promotes §1.8 row + Lane 1 L7 row in r3-program-plan.md with explicit slice-receipts-≠-PASSING discipline preserved

Conformance:

• ✅ Per feedback_naming_is_aliasing — canonical declaration ID matches gate ID; namespace alignment.
• ✅ Per feedback_declare_facts_dont_derive — declares CONSUMER_LANDED at §1.8 authority with concrete evidence (fixture path + integration harness cited inline).
• ✅ Per project_test_modeling — TestClaim discipline preserved; uses canonical AlgebraicLaw::Associativity predicate over Int +.
• ✅ Honest scope discipline: explicit "PASSING = exhaustive per-(algebra, inhabitant, law) coverage; slice receipts ≠ ledger closure" — no premature gate-flip.
• ✅ P5(b) integration-only Rust per worker's own attestation in PR body — no production code paths touched, no SG-0 hand-path delta.

Verification (claude-opus-4-7 APPROVE @ 2026-05-10)

Spot-checked HEAD against your notes:

• Three-way consistency: Fixture data l7_algebraic_laws_witnessed (TestClaim.name = §1.8 gate id, AlgebraicLaw(Associativity, …) on Int +) is first entry in r3_verification_l7_algebra_matrix_suite; integration wires L7_GATE_CLAIM + dedicated l7_algebraic_laws_witnessed_passes_bounded_associativity_witness; docs/r3-program-plan.md §1.8 row Design: Diff Gist Mode for Branch Change Snapshots #10 + T-V-L4-L7-Direct summary row stay CONSUMER_LANDED with explicit PASSING = exhaustive §Acceptance language (incl. §P1 carve for laws outside AlgebraicLawKind).
• Slice discipline: Fixture header still excludes lattice / bounded-lattice / Boolean / free-monoid rows from the passing matrix; matrix allowlist + source probes unchanged in intent.
• P5: New Rust remains under src/v3/compiler/tests/integration/ only; consumer names the gate it exercises.

Merge gate: Waiting on GitHub required checks — v3 was still pending at poll time (mergeStateStatus: BLOCKED). Will squash-merge once rollup is green and GitHub reports a clean merge state (policy: ≥2 approving review artifacts — composer-2 + this thread — and no REQUEST_CHANGES).

1. Story of the diff

This PR turns R3 §1.8 gate #10 from a staged ledger row into a canonical, executable consumer receipt without claiming full L7 closure. The plan ledger now records l7_algebraic_laws_witnessed as CONSUMER_LANDED while explicitly preserving the distinction between bounded slice receipts and exhaustive per-(algebra, inhabitant, law) acceptance coverage (docs/r3-program-plan.md:182, docs/r3-program-plan.md:236). The fixture renames the prior semigroup associativity claim into the canonical gate claim and keeps it scoped to AlgebraicLaw::Associativity over honest Int + (src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag:58–65), then the Rust integration test adds a focused consumer that compiles that fixture, resolves the canonical claim, checks the TestClaim.name, and runs it through TestRunner to require ClaimResult::Pass (src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:235–254).

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

Compliant — this diff does not add or alter substrate types, Dag storage, or cross-pass data carriers; it wires a verification fixture and ledger status. The .dag claim is test/verification data, and the Rust addition is an integration consumer of an existing TestClaim/AlgebraicLaw surface (src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag:62–65, src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:248–254).

1. INVARIANTS.md + modeling-discipline.md.

Compliant — Boundary Discipline / single authority is handled by making the canonical gate identifier the fixture declaration and TestClaim.name, then asserting the lowered claim preserves that exact name before running the claim (src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag:62–63, src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:244–249). Modeling Faithfulness is also preserved: the comments and ledger repeatedly constrain this to the honest Int additive associativity slice and refuse to treat lattice/Boolean/free-monoid obligations as covered before faithful carriers exist (src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:10–15).

1. CODING.md.

Compliant — the Rust change stays in test code, uses a small constant for the canonical claim id (src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:48), and adds one focused free-function test whose body is a direct input → claim → evaluation flow rather than introducing object state or a helper class (src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:235–256). The panic!/assert! usage is in test code and is tied to explicit contract failure.

1. TESTING.md.

Compliant — the PR adds a behavior-driven regression at the right level: the subject is the integrated .dag TestClaim consumer path, so compiling the fixture and invoking TestRunner::run_claim is the relevant interface under test (src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:237–254). The test is one claim: canonical gate claim id must lower structurally and pass the bounded associativity witness.

1. LOCKED DESIGN DECISIONS.

Compliant — no locked substrate/design decision is altered. The ledger explicitly avoids diluting the R3 acceptance rule by saying CONSUMER_LANDED is not PASSING until exhaustive L7 coverage lands (docs/r3-program-plan.md:182, docs/r3-program-plan.md:236).

1. TRACKED vs UNTRACKED DEBT.

Compliant — the remaining work is bounded and named rather than left as vague scaffolding: PASSING is tied to exhaustive per-(algebra, inhabitant, law) coverage, with distributivity/lattice absorption/non-AlgebraicLawKind laws called out as still outside the slice (docs/r3-program-plan.md:236). The fixture and test comments repeat the same dissolution boundary: this row is a consumer hook, not final ROADMAP/L7 closure (src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag:59–61, src/v3/compiler/tests/integration/r3_verification_l4_l7_l5_skeleton_test.rs:258).

2.5. Top-down PM intent review

Compliant — the diff preserves the PM-level intent of making L7 verification structural and executable while not overstating readiness. The new canonical consumer is data-authored as a .dag TestClaim (src/v3/compiler/tests/fixtures/r3_verification_l7_algebraic_laws.dag:62–65), and the ledger text keeps full acceptance gated on exhaustive L7 coverage rather than converting a bounded Int associativity receipt into a semantic closure claim (docs/r3-program-plan.md:182, docs/r3-program-plan.md:236). I do not see a must-have becoming optional, a dissolution target becoming permanent scaffolding, or hand-written implementation replacing the canonical .dag/structural direction.

3. Verdict

APPROVE. The PR cleanly lands the canonical gate #10 consumer and ledger update while preserving the slice-vs-acceptance distinction. I found no diff-cited invariant, testing, coding, or PM-intent issue requiring changes.

Verification (openai-pro gpt-5-5-pro review @ 249f77ce, mirrored in briansrls comment)

Re-checked the merged tree against every cited concern:

• Story / layering: Canonical l7_algebraic_laws_witnessed remains verification-only data + integration consumer; no substrate/Dag carrier churn (r3_verification_l7_algebraic_laws.dag gate hook + TestRunner::run_claim path).
• INVARIANTS / modeling: Declaration id + TestClaim.name still match §1.8 gate id; module + fixture comments still fence lattice / Boolean / free-monoid rows out of the passing matrix and repeat slice ≠ exhaustive §Acceptance.
• CODING / TESTING: Integration change stays in tests/integration/, single-purpose test (L7_GATE_CLAIM → structural TestClaimValue → Pass), consistent with existing L4/L7 harness style.

No findings require a follow-up commit.

Merge readiness: This PR was already squash-merged (mergedAt: 2026-05-10T16:15:52Z). Required CI was green beforehand; no further gh pr merge applies.

(Dashboard artifact line item showing only chatgpt-reviewer bootstrap logs contained no separate actionable delta beyond this APPROVE body.)
