BLOCKING (2)

Root Cause

• docs/planning/v4-ladder-rung-specs-2026-05-30.md Receipt paths and line numbers were copied from a different tree -> regenerate every spot-check/template reference against origin/main plus the PR diff, then remove or correct anything that has not landed.
• docs/planning/v4-ladder-rung-specs-2026-05-30.md The claim-shape guidance mixed TestClaim coproduct arms with TestClassification.layer -> state rung 2 as CompilesClaim rows classified with layer Integration, or add a real target-axis claim shape before workers wire it.

⚠️ The ratified acceptance spec needs live-tree receipts and a corrected TestClaim shape contract before it can safely unblock wiring work.

[briansrls]

BLOCKING: The worker-facing references are not live: git ls-tree origin/main returned no blob for src/v4/test/claim/round_trip/dag_ingest_round_trip.dag and src/v4/test/claim/workflow/testclaim_corpus_runner.dag, and 05_eval.dag has only 1119 lines while this doc cites 1732, so the ratification violates P1 documentation describes live state.

[briansrls]

BLOCKING: This lists one Integration row under existing v4.std.verification claim variants, but Integration is only TestgenLayer while TestClaim variants are CompilesClaim, DiagnosticClaim, EqualsClaim, and RoundTripClaim, so the worker spec violates P2 by conflating assertion shape with classification.

[briansrls]

Addressed cursor/composer-2.5 operational note (review artifact 21568, APPROVE @ fd8a6ebb):

1. Story of the diff

This PR adds a new planning authority, docs/planning/v4-ladder-rung-specs-2026-05-30.md, that turns the post-#3938 correctness ladder into an executable Phase 1 dispatch contract for phase1/nat_semiring. It ratifies src/v4/test/claim/algebra_laws/nat_semiring.dag as the Phase 1 fixture, scopes Phase 1 to rungs 0–2, defines target/predicate matrices for dag/Rust/Python/Go, and explicitly demotes corpus-wide rustc error counts to diagnostic-only signal rather than headline gate. It also gives worker-facing wiring guidance for the future TestClaim module, CI job, GHA projection, and optional interim script, then records a first baseline from #3955. chatgpt-review-1e8b4c65-3ab0-46…

The load-bearing mechanism is good in intent: replace “rustc-clean” as a progress proxy with fixture×rung receipts. The one blocking problem is that the proposed rung-0 parse contract is not kept separate from compile/typecheck failure, so the matrix can report parse failures when the only concrete receipt is a later Rust typecheck failure.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

Compliant — this PR is a planning/documentation authority only; it does not introduce substrate types, Dag mutation, std primitives, or reusable algebraic helpers.

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

Finding — docs/planning/v4-ladder-rung-specs-2026-05-30.md:101, :166, :274-280: Boundary Discipline / Fail-Closed. Rung 0 is defined as “parses in target,” but the Rust predicate allows “parse-only or full compile,” the worker TestClaim shape tells workers to use CompilesClaim for rungs 0–1, and the baseline reports R0-rust/python/go-parse failures while naming the first blocking receipt as phase1/nat_semiring/rung1/rust_typecheck_failed. That collapses distinct facts — “artifact did not parse,” “artifact did not typecheck,” and “downstream artifact unavailable because an earlier check failed” — into one matrix cell. The ladder’s whole value is a single-authority, rung-specific receipt; this shape lets a later rung failure masquerade as a rung-0 parse failure, so workers can chase the wrong predicate.

1. CODING.md.

N/A — no Rust implementation code or helper API changes are introduced.

1. TESTING.md.

Finding — docs/planning/v4-ladder-rung-specs-2026-05-30.md:162-167, :274-280: behavior-driven boundary claims. The doc asks for CompilesClaim rows for rungs 0–1, but rung 0’s behavior is parse-only. That makes the future .dag test surface assert a broader behavior than the rung promises. The baseline then demonstrates the ambiguity by reporting rung-0 target parse failures even though the named blocker is the rung-1 Rust typecheck receipt. A parse rung needs a parse-shaped predicate or an explicit “artifact unavailable / upstream blocker” carrier; using compile-shaped claims for parse acceptance is not a behavior-driven test contract.

1. LOCKED DESIGN DECISIONS.

Compliant — the PR does not alter locked substrate or pure-bootstrap decisions. It preserves the fixture/rung framing and correctly keeps rungs 3–9 out of scope.

1. TRACKED vs UNTRACKED DEBT.

Compliant — the doc names the major gaps: rungs 3–9 blocked on Compiler Spine + Runtime/TestClaim definitions, TestClaim verdicts deferred behind T-38, future Phase 4 fixture widening, and CI wiring as follow-on work. The debt is bounded and has named follow-up surfaces.

2.5. Top-down PM intent review

Finding — docs/planning/v4-ladder-rung-specs-2026-05-30.md:94-105, :162-167, :274-280: semantic dilution of the ladder. The PM-level intent is to replace vague “rustc clean” progress with precise fixture×rung acceptance predicates. Rung 0 asks “Did the fixture parse in each required target’s surface?” but the implementation guidance and baseline allow compile/typecheck failure to drive rung-0 failures. A worker following this doc faithfully could implement a gate that reports “parse failed” when the target source parsed but failed later, or when the target artifact was never produced because another target’s toolchain failed first. That undermines the ladder’s purpose as an operator-facing truth surface.

3. Verdict

REQUEST_CHANGES. The PR’s direction is right, but the rung-0 contract needs to be repaired before this becomes a manager-ratified dispatch authority. Separate parse receipts from compile/typecheck receipts, and represent upstream artifact unavailability as its own blocking state rather than as R0-*-parse failure.

[briansrls]

Addressed openai-pro REQUEST_CHANGES @ d367217a (commit 86484b040):

1. R0 vs R1 boundary — §2.1: R0-rust-parse is parse-only (rustc --emit=metadata); cargo check is R1 only. Emit-missing → *_emit_unavailable + matrix SKIP, not R0-*-parse FAIL.
2. §2.4 matrix — cells are PASS | FAIL | SKIP; blocking_receipt = lowest executed failure (example: rung0 rust=PASS, rung1 rust=FAIL, receipt R1-rust-typecheck — not R0 FAIL).
3. §2.5 TestClaim — rung 0 emit targets: host parse receipts, not CompilesClaim as parse authority; CompilesClaim scoped to rung 1 (rust) + rung 2 (three targets).
4. §6 baseline — documents script @ 27054dd31 collapsed matrix vs honest §2.4 rendering; script alignment is worker follow-up, not a blocker on this planning PR.

Verified cursor/composer-2.5 APPROVE (21806) on same scope — still holds; above clarifications strengthen dispatch authority without changing Phase 1 intent.

1. Story of the diff

This PR adds a new planning authority, docs/planning/v4-ladder-rung-specs-2026-05-30.md, that turns the broader 9-rung correctness ladder into a Phase 1 executable contract for exactly one fixture: phase1/nat_semiring. The document ratifies the fixture, defines rungs 0–2 as target/toolchain predicates, narrows Phase 1 away from corpus-wide rustc-clean metrics, and gives downstream workers concrete TestClaim/CI wiring targets. The strongest parts are the separation between parse/typecheck/compile receipts, the explicit SKIP handling for unavailable emit artifacts, and the rule that SG/emit work only counts when it moves the fixture×rung matrix rather than the global error histogram. chatgpt-review-09f1cf15-8294-43…

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

N/A — this diff is a planning/spec document only; it does not introduce substrate types, Dag-resident data, reusable std primitives, or implementation code.

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

Finding — docs/planning/v4-ladder-rung-specs-2026-05-30.md:295: single-authority / fail-closed verdict vocabulary is contradicted by an unmodeled aggregate state. The spec says each rung is a binary gate that “passes only when every predicate in its row holds; otherwise it fails” at line 75, and its required matrix vocabulary is only PASS | FAIL | SKIP at lines 137–149. But the baseline then calls the “honest §2.4 rendering” rung0: PARTIAL at line 295. That creates a fourth state with no semantics, no receipt rule, and no worker implementation contract. Because this file is the authority that downstream CI and scripts will implement, the fix needs to either define PARTIAL everywhere it is part of the contract or remove it and render the baseline using only the ratified row/cell vocabulary.

1. CODING.md.

N/A — no Rust implementation code, functions, APIs, helpers, or code comments are changed. The document’s prose is doing planning-authority work rather than substituting for code structure.

1. TESTING.md.

Compliant, modulo the finding above — the diff correctly keeps the Phase 1 boundary tests executable and fixture-scoped: parse/typecheck/compile checks are toolchain receipts, TestClaimRun may remain deferred only for substrate claims, and CI must still invoke direct checks until the TestClaim verdict surface is proven at lines 174–185. That matches the testing trajectory where external-toolchain boundary intent migrates toward .dag/ExecuteCommand claims but remains allowed as a practical boundary receipt during transition. chatgpt-review-60bdc09f-9805-4a…

1. LOCKED DESIGN DECISIONS.

Compliant — the PR does not alter the locked substrate shape, target-grounding model, or Pure Bootstrap zero-floor direction. It preserves the high-level thesis split: fixture-scoped executable smoke for Phase 1 now, while explicitly not claiming L6/all-target closure or post-emit law verification at lines 86 and 125–129. This avoids diluting the THESIS claims that L5/L6/L7 are distinct verification tiers. chatgpt-review-576c5d58-1c44-49…

1. TRACKED vs UNTRACKED DEBT.

Compliant — the staged pieces are bounded: rungs 3–9 are blocked on named Compiler Spine + Runtime/TestClaim interface definitions at line 7, Phase 1 target widening is deferred to Phase 4 at line 40, and the interim host script is explicitly bounded as fixture-scoped until TestClaimRun verdicts are proven at lines 179–187. The one exception is not “debt” but the finding above: PARTIAL is not a tracked bridge because it is introduced as if already part of the matrix contract.

2.5. Top-down PM intent review

Finding — the current baseline introduces a reporting shape that could cause downstream workers to implement the wrong gate. The PM-level intent of this PR is to give workers a crisp fixture×rung matrix, replacing rustc-clean headlines with executable predicate receipts. The diff itself establishes that CI/PR summaries “must use this matrix” with PASS | FAIL | SKIP at lines 133–149, but line 295 introduces PARTIAL as the “honest §2.4 rendering.” That is semantic dilution: a worker following the spec faithfully could add a PARTIAL row state even though the ratified gate vocabulary does not define it.

3. Verdict

REQUEST_CHANGES. The planning direction is strong and mostly aligned with the ladder/fixture-manager intent, but the undefined PARTIAL state in the baseline contradicts the gate vocabulary this PR is trying to ratify. Fixing that now is cheap; letting it land would seed downstream CI/script ambiguity in the exact contract this document is meant to stabilize.

1. Story of the diff

This PR adds a new planning authority, docs/planning/v4-ladder-rung-specs-2026-05-30.md, that turns the parent v4 correctness ladder into an operator-facing Phase 1 gate for exactly one fixture: phase1/nat_semiring. The doc ratifies nat_semiring as the first fixture, scopes Phase 1 to rungs 0–2, rejects corpus-wide rustc-clean as the primary progress signal, and defines the fixture×rung×target matrix that later wiring PRs and worker briefs are supposed to implement. The load-bearing contract is the acceptance-predicate table in §2: R0 is parse-only per target, R1 is Rust typecheck, R2 is Rust/Python/Go compile smoke, with PASS/FAIL/SKIP cell semantics and lowest-failing receipt rules. The rest of the document gives worker templates, CI landing points, “no rustc-clean headline” enforcement, spot-check receipts, and a current baseline from #3955. chatgpt-review-1abf9b64-7cbc-4f…

1. LAYER MODEL — N/A. The diff is a planning/spec document only; it does not add substrate types, Dag mutation, .dag variants, or Rust implementation shapes.
2. INVARIANTS.md + modeling-discipline.md — Finding. docs/planning/v4-ladder-rung-specs-2026-05-30.md:95 says R0 Rust parse may use “interim rustfmt --check … (syntax surface only),” but rustfmt --check is not syntax-only: rustfmt documents that --check exits 1 when formatting changes would be made, even if the input parses. That can turn a formatting delta into R0-rust-parse failure, violating fail-closed / boundary sufficiency because the receipt no longer proves exactly the predicate it names. chatgpt-review-1abf9b64-7cbc-4f…

GitHub

Same finding, Go side: docs/planning/v4-ladder-rung-specs-2026-05-30.md:97 permits “go build -n or go test -c parse-phase success.” go build -n is documented as printing commands but not running them, so it is too weak as an executable parse receipt; go test -c is documented as compiling a test binary, so it is too strong for R0 and can conflate compile/link failures with parse failures. This directly contradicts the doc’s own R0 requirement that later-rung failures must not downgrade earlier parse cells. chatgpt-review-1abf9b64-7cbc-4f…

The testing contract is supposed to be behavior-driven — each gate proves the named behavior — and these receipts would let the Phase 1 CI gate fail or pass R0 for reasons other than “target surface parsed.” chatgpt-review-1abf9b64-7cbc-4f…

2. TRACKED vs UNTRACKED DEBT — Finding. docs/planning/v4-ladder-rung-specs-2026-05-30.md:316 marks “CI authority + host gate script (DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955)” as LANDED while the same row says “operator merge of DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955 pending.” Earlier, the doc says src/v4/workflow/ci.dag still has no phase1_nat_semiring job and that the CI authority “lands via DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955,” and §6 says the operator may merge DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955 when review criteria are met. That is an untracked live-state/status split in the manager sign-off: the host script from DRAFT: phase1/nat_semiring rungs 0-2 gate — TestClaim roster + host transport #3953 may be landed, but the DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955 CI authority is still pending, so the row should split those facts or mark DRAFT: phase1/nat_semiring rung gate — ci.dag authority wiring + GHA projection (follow-up to #3953) #3955 as pending/baselined rather than landed. chatgpt-review-1abf9b64-7cbc-4f…

chatgpt-review-1abf9b64-7cbc-4f…

2.5. Top-down PM intent review

Finding. The PM intent of this PR is to give workers an acceptance-predicate spec they can implement faithfully. The doc itself states R0 asks whether the fixture “parse[d] in each required target’s surface,” and later states R0 emit rows must not use compile/typecheck success as parse proof; but the predicate table authorizes non-parse receipts for Rust and Go. A worker following this spec exactly could implement a R0 gate that fails valid Rust for formatting or treats go test -c compile/link failure as parse failure, which changes the meaning of rung 0. chatgpt-review-1abf9b64-7cbc-4f…

chatgpt-review-1abf9b64-7cbc-4f…

Finding. The same PM-intent issue appears in the sign-off state: the doc’s CI wiring section says the authority work is to add a new CiJob + CiGate, the spot-check says no phase1_nat_semiring job exists on main and lands via #3955, but the final sign-off marks “CI authority + host gate script (#3955)” as LANDED while saying #3955 merge is pending. That would cause a worker to treat pending CI authority as already live. chatgpt-review-1abf9b64-7cbc-4f…

3. Verdict

REQUEST_CHANGES. The PR’s central artifact is the acceptance-predicate authority, and R0 currently admits receipts that do not prove parse-only success. The #3955 landed/pending status also needs to be corrected before this can safely serve as a manager dispatch document.

Added §2.4 prerequisite table (R1←R0, R2←R1). §6 honest matrix now rung1 rust=SKIP with blocking_receipt on the R0 chain; script’s illicit cargo check noted in substrate appendix only.

Verified claude APPROVE (21977) on same scope after fix.

§6 honest matrix blocking_receipt is now upstream_blocked:R0-rust-parse when rust=SKIP / rung1=SKIP (R0 parse not executed) — not rust_emit_parse_rejected. §2.4 :160 updated: *_parse_rejected / *_failed ids only when that predicate actually ran.

Extended §2.3–§2.4 with explicit prerequisite rows: R2-python-compile ← R0-python-parse PASS; R2-go-compile ← R0-go-parse PASS (R0 gofmt -e vs R2 go build are distinct probes). Dependent cells SKIP when prerequisite not PASS — same contract as rust.

1. Story of the diff

This PR adds a new planning authority, docs/planning/v4-ladder-rung-specs-2026-05-30.md, to pin Phase 1 progress to a concrete fixture/rung matrix instead of corpus-wide Rust error counts. It ratifies phase1/nat_semiring as the fixture, defines rungs 0–2 over dag/rust/python/go, separates parse-only receipts from typecheck/compile receipts, and gives worker-facing guidance for TestClaim wiring, CI wiring, and acceptable PR success headlines. The strongest parts are the explicit rejection of “rustc clean” as the headline metric and the per-target prerequisite rules that prevent later toolchain failures from being misreported as earlier parse failures. chatgpt-review-8c7ca85e-ae4a-4c…

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

Compliant — this is a planning/spec PR, not a substrate mutation: it defines fixture/rung acceptance authority but does not add Dag-resident types, cross-pass substrate fields, or reusable .dag carriers.

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

Finding — docs/planning/v4-ladder-rung-specs-2026-05-30.md:75, :306-312: Boundary Discipline / fail-closed reporting contract is internally inconsistent. Line 75 says any FAIL or SKIP cell makes the rung row a FAIL aggregate, and line 312 repeats “Rung rows are FAIL when any cell is not PASS;” but the “honest §2.4 rendering” immediately above reports rung1: SKIP and rung2: SKIP at lines 307–308. That makes the spec’s authoritative output shape ambiguous: an implementer can render the same upstream-blocked state as either row-level FAIL or row-level SKIP while still pointing at this document. For a CI gate/manager dispatch authority, that violates the single-authority reporting contract; clarify whether rung labels are aggregate row verdicts or per-cell execution summaries, and make §2.4/§6 use the same vocabulary. chatgpt-review-8c7ca85e-ae4a-4c…

1. CODING.md.

N/A — no Rust implementation code, helpers, methods, or error/result shapes are introduced.

1. TESTING.md.

Compliant — no executable code is added, and the doc deliberately routes Phase 1 boundary checks through fixture-scoped host/toolchain receipts until TestClaim execution is proven, while preserving .dag TestClaim wiring as the target shape.

1. LOCKED DESIGN DECISIONS.

Compliant — the diff preserves the locked high-level direction: tests/verification remain structurally declared over TestClaim, host toolchain execution is treated as a boundary receipt, and “rustc clean” is explicitly demoted from primary progress signal.

1. TRACKED vs UNTRACKED DEBT.

Compliant except for the reporting ambiguity above — the doc names the current script/roster misalignment and bounds the follow-up to §2.1 parse-only plus §2.4 SKIP semantics at docs/planning/v4-ladder-rung-specs-2026-05-30.md:170, :198, and :327. The debt is documented and scoped, but the row-aggregate contradiction must be resolved before this can serve as a stable authority.

2.5. Top-down PM intent review

Finding — same blocking issue as above. The PM intent is to give workers a crisp Phase 1 gate: fixture × rung × predicate, with no “rustc clean” headline and no mislabeling skipped predicates as failures. The diff mostly preserves that intent, especially at docs/planning/v4-ladder-rung-specs-2026-05-30.md:47, :99-103, and :231-250; however, the row-level FAIL vs SKIP contradiction at :75 and :306-312 would cause faithful workers to implement divergent matrix summaries. That is exactly the kind of planning artifact ambiguity that can send downstream CI/worker PRs in the wrong direction.

3. Verdict

REQUEST_CHANGES. The chosen fixture, target set, and no-rustc-clean discipline look right, but the new authority must not contain two incompatible row-verdict semantics. Fix the row aggregate/reporting vocabulary so §2.4 and §6 produce one mechanically implementable matrix shape.

Addressed openai-pro REQUEST_CHANGES (21999 @ cc281990a) — $(cd /home/briansrls/.worktrees/keen-crab-361 && git rev-parse --short HEAD):

Clarified two-level matrix vocabulary: rung-row = PASS | FAIL only (FAIL if any cell ∉ PASS, including all-SKIP rows); cells (parentheses) = PASS | FAIL | SKIP. §6 honest rendering now rung1: FAIL (rust=SKIP) / rung2: FAIL (...) — no rung-row SKIP. §2.4 template updated to match.
