Verification (dashboard review /api/reviews/10371)

Re-checked current HEAD against the relayed finding — the verdict stands; no follow-up commit is required for this delta.

  • Scope: Single commit 98c9fca6e — worker brief docs/briefs/r3-wave1-pb2-fixedpoint-gate16-r3-horizon-worker.md, cross-links in docs/db-history/db-8.md, docs/r3-remaining-work-dependency-graph.md, comment-only lines in .github/workflows/ci.yml (self_host_ratchet), module docs on self_host_fixed_point.rs, and // commentary in src/v3/std/verification.dag adjacent to FixedPointConverges (same pattern as existing scaffold notes).
  • Semantics: No changes to TestPredicate variants, test_runner evaluation paths, R1 release acceptance wiring, or substrate shapes — only documentation and non-semantic DAG comments reinforcing two-horizon discipline and dispatch gating for pb_self_compile_fixed_point_strong.

The relay artifact describes an APPROVE with no actionable defect; there is nothing to fix unless a separate review cites a concrete issue.

Verification (dashboard review /api/reviews/10389 — cursor/composer-2)

Re-checked PR HEAD b4098783b against the relayed artifact: Findings None / Verdict APPROVE still matches the tree.

  • Shape: Wave-1 brief + db-8.md / dependency-graph / CI comment cross-reads; non-semantic // banner before FixedPointConverges in src/v3/std/verification.dag (dispatch gating + P1-style “no shadow/rename without substrate ack”); self_host_fixed_point.rs rustdoc two-horizon pin; bootstrap_generated*.rs span refresh after merge-from-main + comment line drift; no new steady-state Rust control paths.
  • Semantics: R1 vs R3 boundary prose matches code reality (R1 gate still verification.dag + runner; DB-8 CI remains non-authoritative for that bar).

No commit required for this review artifact — it is an approval with zero actionable defects.

Item 1 — dashboard /api/reviews/10402 (cursor/composer-2 on 71483b82)

Verified against PR HEAD 71483b82: The artifact’s characterization matches the tree (Wave‑1 brief + db-8 / dependency-graph / CI notes; non-semantic FixedPointConverges banner in src/v3/std/verification.dag; self_host_fixed_point rustdoc two‑horizon pin; bootstrap span regen after .dag / merge drift; no new evaluation paths, no sg0_census_test edits). Findings: none in the human sense of the log; Verdict: APPROVE stands. No code commit required for this review.

Merge-readiness (re-evaluated now)

  • GitHub checks: fmt, changes, ci pass; v3 still pending on run 25761390421 (not green yet → cannot claim full CI rollup).
  • mergeable: MERGEABLE (GitHub).
  • dashboard-ops reviews on this URL: merge_criteria.ready is false — checks_state pending and 0/2 distinct dashboard approvals on current head_sha 71483b82. Review 10402 is attached to that SHA but the dashboard parser records verdict: "unknown" (artifact text still contains an explicit APPROVE); older reviews 10371 / 10389 are approve but on prior SHAs, so they do not satisfy the dashboard’s current-HEAD approval rule as reported.
  • REQUEST_CHANGES: none reported.

Conclusion: I am not running gh pr merge yet — v3 not finished and dashboard merge gate is not ready even aside from v3. Next step is wait for v3 green, re-run dashboard-ops reviews, and have PB Mgr (or automation) ensure two parsed approvals on the green HEAD (or whatever the program’s merge script keys off — possibly fixing stdout format for 10402 if unknown is unintended).

Item 1 — codex api-review (sha b4098783, posted 2026-05-12T21:02:54Z)

Verified against current PR HEAD 71483b82: 71483b82 is b4098783 + merge origin/main only; it does not revert the Wave‑1 PB2 slice. Spot-checked PR ref: gate #16 // banner before FixedPointConverges, self_host_fixed_point rustdoc cross-reads, brief + db-8 / graph / CI alignment — unchanged in intent from what codex reviewed. The codex conclusion (R1/R3 split preserved; no new pass/fail or substrate surface) still holds for the delta on HEAD.

GitHub review object: GraphQL shows this submission as state: COMMENTED (not APPROVED), so reviewDecision stays null — that is a metadata shape issue for branch-protection semantics, not a finding that requires a code fix.

No commit from this item.


Merge-readiness (re-evaluated after v3 finished)

  • GitHub statusCheckRollup: fmt, changes, ci, v3, self_host_ratchet → all SUCCESS on 71483b82.
  • mergeable: MERGEABLE.
  • dashboard-ops reviews: still reports merge_criteria.ready: false — checks_state: "pending" (stale vs GitHub rollup in this read) and 0/2 distinct dashboard approvals on head_sha because review 10402 (composer-2 on 71483b82) is stored as verdict: "unknown" despite an APPROVE body, and older composer approve rows are on prior SHAs.

I am not running gh pr merge here: per program merge discipline, dashboard ready is still false and there is no second parsed approving provider on HEAD in that summary; formal GitHub APPROVED reviews are also absent. PB Mgr / operator needs to clear merge gate (re-run dashboard reviews after sync, second provider, or adjust review artifact parsing) before squash-merge.

Verification — dashboard /api/reviews/10418 (cursor/composer-2)

Re-checked current PR HEAD caf773e6 (matches review sha on dashboard): the artifact matches the tree.

  • P0 alignment: Wave‑1 worker brief + db-8 / dependency-graph / CI cross-reads; non-semantic // block before FixedPointConverges in src/v3/std/verification.dag:417 (dispatch / two-horizon STOP language); self_host_fixed_point.rs rustdoc still pins R1 vs R3 and DB‑8 posture.
  • Mechanical bootstrap: bootstrap_generated*.rs remain generated span fixtures consistent with .dag edits — no new TestPredicate variants or runner semantics in this slice.

Findings: none in the sense of the relayed log; Verdict: APPROVE stands. No code commit required for this review.

(dashboard-ops reviews still had checks_state: pending when read — v3 was in flight on GitHub; merge gate is separate from this approval artifact.)

Verification — dashboard /api/reviews/10451 (codex/codex-default)

Checked current PR HEAD dac0f9f against the relayed artifact — Verdict APPROVE / no findings still matches the tree.

  • src/v3/std/verification.dag: Only // framing was added adjacent to FixedPointConverges (see lines 417–422 on this HEAD; line 409 in the artifact link is the same TestPredicate block region — FixedPointConverges variant shape at 423–426 is unchanged from R1 semantics).
  • self_host_fixed_point.rs: Module docs at L1–L32 remain documentation-only (two-horizon + DB-8 / D-1 / gate-71); no new control paths.
  • bootstrap_generated*: Still span/regen fallout from the comment insert + merges, not a second evaluation authority.

No commit required for this review.

Non-blocking — Strengths

  • docs/briefs/r3-wave1-pb2-fixedpoint-gate16-r3-horizon-worker.md Wave-1 scope is bounded to P0/P1 pins unless parent preconditions hold, preserving the R1/R3 fixed-point horizon split.
  • src/v3/std/verification.dag The added comment documents the dispatch gate without introducing a new TestPredicate variant or changing R1 FixedPointConverges semantics.

✅ No blocking concerns found; the remaining Rust snapshot churn is span-only regeneration from the verification.dag comment.

Verification — reviews /api/reviews/10468 (claude-opus-4-7) + codex api-review sha:c9bd2d97

Current PR HEAD: d0b04430 (fetched pull/2783/head).

/api/reviews/10468 (claude)

Re-checked: Wave‑1 brief + db-8.md / r3-remaining-work-dependency-graph.md / CI notes + self_host_fixed_point.rs module docs + only // lines 417–422 before FixedPointConverges (423–426 unchanged). No new TestPredicate variants; R1 pb_self_compile_fixed_point evaluation unchanged in substance. bootstrap_generated*.rs remains explainable as span/regen fallout from the .dag comment insert + merges, not new AST shape. APPROVE / no findings stands — no commit.

codex c9bd2d97 (briansrls api-review)

c9bd2d97 is in the ancestry of d0b04430 (merge-base --is-ancestor → true). The strengths called out (bounded Wave‑1 brief; dispatch comment without enum/semantic change; span-only churn) still describe the PB2 slice on HEAD. No blocking concerns — no commit.

Item 1 — dashboard /api/reviews/10485 (codex/codex-default)

Verified against current PR HEAD 8d47c400 (matches review sha on dashboard): the artifact is accurate.

  • Scope: Docs / rustdoc / CI / graph cross-reads + comment-only block 417–422 before unchanged FixedPointConverges (423–426); regen churn in bootstrap_generated* is span fallout, not new AST or predicate surface.
  • Two-horizon / authority: R1 gate semantics unchanged; R3 strengthening stays explicitly dispatch-gated in prose — no silent rename of the R1 claim.

Verdict: APPROVE — no fix commit.


Merge-readiness (now)

No gh pr merge from sharp-deer-601 in this pass — wait for v3 SUCCESS, then PB Mgr squash-merge (or explicit ask to merge from this worker).

Verification — dashboard /api/reviews/10501 (cursor/composer-2)

Re-checked PR HEAD d6e889e (matches dashboard sha for review 10501) against the relayed diff narrative: Wave‑1 gate #16 brief + cross-links (db-8, dependency graph, CI) + verification.dag comment-only framing before FixedPointConverges + self_host_fixed_point rustdoc + bootstrap_generated* span regen — no substrate / behavioral / R1 pass-fail change. DB‑8 job called out as non-authoritative for the R1 claim; strong suite stays dispatch-gated in prose.

Findings: none actionable. Verdict: APPROVE stands — no commit.

Exploratory (reviewer optional): Brief still has no explicit ROADMAP.md row citation (only r3-pb-t-fixedpoint-worker.md, r3-program-plan.md, etc.). Per the artifact, that is not a P0 functional gap; treating it as optional polish / follow-on if P5 deferral wording ever needs a concrete ROADMAP anchor.

Item A — /api/reviews/10515 (cursor/composer-2)

Verified on PR HEAD ca25d08f (matches dashboard sha for 10515): Wave‑1 brief + cross-links + CI/db-history/graph prose + verification.dag comment-only guard before FixedPointConverges + self_host_fixed_point module docs + bootstrap_generated* span sync — no second pass/fail authority, no R1/R3 conflation, P5 framing satisfied via brief + explicit P0 pin language. Findings: none. Verdict: APPROVE — no commit.

Item B — codex api-review sha:8d47c400 (briansrls)

8d47c400 is ancestor of ca25d08f; the codex “no blocking concerns / stays within gate #16 authority” read still applies to the PB2 slice on HEAD.

No commit.


Merge-readiness (this moment)

  • dashboard-ops reviews: merge_criteria.ready: true, 2/2 dashboard approvals (codex + cursor), no REQUEST_CHANGES, checks_state: passing (rollup incl. v3 + self_host_ratchet SUCCESS on workflow 25766410098).
  • GitHub API (mergeStateStatus / mergeable): reports DIRTY / CONFLICTING — cannot gh pr merge --squash until the branch is rebased/merged with main and conflicts cleared (dashboard mergeable: MERGEABLE was stale vs GitHub here).

No squash-merge from sharp-deer-601 — resolve GitHub merge conflicts (or merge origin/main into the PR branch) first; PB Mgr can drive that unless you want this worker to take another merge-from-main pass.

- Cross-link self_host_fixed_point, db-8, verification.dag, and CI to
  r3-program-plan §1.8 #16 and r3-pb-t-fixedpoint-worker (two-horizon
  discipline; strong suite remains dispatch-gated).
- Point PB2 row in r3-remaining-work-dependency-graph at the brief.

No R1 verification.dag claim or test_runner semantics changed.

Item 1 — /api/reviews/10530 (codex/codex-default)

Verified: Dashboard review 10530 targets 4712063dd; that commit is in the ancestry of current PR HEAD ac7621b24 (post-rebase stack). Spot-checked ac7621b24 at the cited surfaces:

  • .github/workflows/ci.yml ~591–594: self_host_ratchet comments still separate DB‑8 / continue-on-error posture from the R1 pb_self_compile_fixed_point bar (verification.dag + test_runner).
  • docs/db-history/db-8.md §gate docs: Add Appendix A with DAG modules, interfaces, and type definitions #16: two-horizon + dispatch-gated strong suite — unchanged intent.
  • self_host_fixed_point.rs L3+: P0 rustdoc pin only.
  • src/v3/std/verification.dag:417+: comment-only guard before unchanged FixedPointConverges; bootstrap churn remains span/regen-consistent.

Verdict: APPROVE — no commit.


Merge-readiness

  • GitHub gh pr checks: fmt / changes / ci pass; v3 pending on run 25767482395 → not full green yet.
  • dashboard-ops reviews: still keyed to older head_sha 4712063dd with checks_state: pending — re-run after green HEAD if you need ready: true on ac7621b24.
  • Squash-merge: not executed — v3 in flight + prior PB Mgr handoff (nimble-crab-786 owns merge unless you explicitly reassign).

§1.5 lane status row T-LensProducer-Retirement: drop stale "valiant-otter-715

without closing their gates per Director audit (msg_312fead3); files at HEAD

Replace with: gate #5 redispatched 2026-05-13 under R3 PB Mgr tidy-raven-311
(work-item adhoc-0cb1ea52-4ab against existing brief
`docs/briefs/r3-pb-t-lensproducer-sub1-lens-apply-retirement.md`); gate #7
sequencing-held pending `BinShimFilesSubsetPredicate` substrate landing in
`src/v3/std/verification.dag` (only `LensProducerFilesSubsetPredicate`
precedent at `:44`/`:46` exists at HEAD; brief shape ratified 2026-05-09 via
gunbc#2068 c#4411574142 but carriers not yet in `verification.dag`).
