Resolves #17661

Evidence: L2 (pure-predicate arms plus composed service-projection arms, the gate mutation-proved red) → L2 required (every AC governs predicate rules and resolver behaviour, all decidable without a running plane). Residual: none.

🌿 An APPROVED badge says a verdict exists. It never says the verdict was one our rules accept.

validateMergeReady claimed to validate "the full review/merge contract" in five rules. §6.1's cross-family mandate was not among them, and rule 2 — reviewDecision === 'APPROVED' — cannot stand in for it: GitHub models no notion of model family, so no field it exposes can express the gate.

AC Evidence

AC Proof
AC-1 the live incident, pinned. The referenced PR's real pre-merge values — OPEN / null / APPROVED / checksGreen / CLEAN / [] — returned strictMergeReady: true with zero blockers and zero advisories, its only approval same-family. The arm asserts the blocker names the author family AND the approving families, since a blocker that names neither sends the reader back to the API
AC-2 the positive control. The same otherwise-identical surface with a genuinely cross-family approval returns true — the arm that stops the fix from being "always false"
AC-3 NON-VACUITY. The blocking arm uses the incident's exact field values rather than a constructed case, so it exercises the shape that actually shipped green. Mutation-proved RED below
AC-4 unresolved blocks. An unresolved verdict fails closed like checksGreen / mergeStateStatus / reviewRequests; the arm asserts the blocker names "was not resolved". The composed-service arm covers the unfetched-connection half: an unreadable review connection now blocks rather than certifying
AC-5 a third family satisfies it — authorFamily: 'gpt' cleared by a gemini approval. No allowlist anywhere: the rule is difference, so a roster change cannot rot it
AC-6 APPROVED-only coverage. Three-state arm: the same cross-family reviewer at COMMENTED and CHANGES_REQUESTED does not satisfy the mandate, at APPROVED it does. This was true in the other direction before the change
AC-7 the unrostered author blocks with its OWN reason. The arm asserts the mandate-breach message is absent — reporting a breach for an external contributor would send the reader hunting a reviewer who was never required. See the delta below: my original fail-open framing was wrong and a fixture corrected it
AC-8 the report consumer still renders. activePrCycleSection's Golden Path arm passes, and the boolean wrapper keeps its shape — verified by the full 1362-test run rather than by inspection
AC-9 unknown COUNTS as differing — operator ruling, 2026-08-24. I shipped the opposite first, arguing a family nobody can state cannot be shown to differ, so certifying on it promises a guarantee nobody can make. Sound reasoning, not the chosen trade: a guest seat whose approvals can never unblock anything has no merge-path value, and for a Claude-family author it is two eligible cross-family seats versus three. The cost is recorded at the constant rather than buried — admitting unknown assumes part of what the mandate checks. The arm asserts the decision: an arm that merely observed 'unknown' !== 'claude' would pass under either policy and could not tell a future reader which was chosen, so it also pins that two unknown seats do not differ from each other
AC-10 seat liveness is deliberately not consulted. The gate asks what an approval WAS, not who is available now — a benched peer's past approval was still genuinely cross-family. Operator-confirmed. It also keeps merge eligibility from being handed out by identityRoots.mjs, whose participationStatus rows are known stale (@neo-opus-vega's census: kimi seats recorded active while benched). That is a data-accuracy defect with its own owner, not a gate defect — and it is exactly why the gate reads family rather than availability
AC-11 the canonical §5 author decides, not the opener. The gate read author.login, so a body declaring a Claude author opened under a GPT login certified on a same-family approval — opener drift deciding merge eligibility. Fixed via resolveAuthorFamilyFromLogins: the self-id wins, the opener is the fallback, and the snapshot carries the derived login rather than the body, so a declared-author change invalidates the drift-compared read while a prose edit does not. That was declared a residual in the first cut; @neo-gpt-emmy found the answer I had not looked for. Mutation-proved: reading the opener reddens the drift arm alone
AC-12 a negative over a truncated window is UNRESOLVED. reviews(last: 100) is a suffix, so a qualifying older approval can sit outside it. A positive witness inside is decisive; finding none is missing evidence, not evidence of absence, and no longer reports the factual "mandate unsatisfied". Both controls asserted. This also made the query's own JSDoc stale — it stated hasPreviousPage gates nothing because "truncation cannot change any decision this query feeds", true until the mandate became one of them. Corrected there with the distinction: the same flag is inert for the approval anchor and load-bearing for the mandate, because "the latest approval" and "any approval" are different questions over one bounded list
AC-13 docblock scope.
AC-14 operator-legible blocker text. The message names both families, the mandate by file and section, and why an APPROVED badge is not evidence of it — written for the person doing the merge, who does not read pull-request-workflow.md mid-merge. The unrostered variant instead says the author family did not resolve and names the login

Deltas from ticket

  • The mechanism already existed, and the ticket's Fix was corrected at source before I wrote a line. My first draft described building family resolution into the validator. ai/services/graph/agentFamilyResolution.mjs already exports resolveAuthorFamily, resolveReviewerFamily, groupReviewsByFamily and hasCrossFamilyReview — all unit-tested, and wired only to a Golden Path report line, never to a gate. So this adds no resolver. It gives that module a verdict-returning form and consumes it. The ticket body carries the correction with the old framing struck.
  • Two defects surfaced while wiring, both now fixed here. (1) The coverage predicate counted reviews of any state, so a cross-family COMMENT read as coverage. (2) An unresolvable author family was collapsed into true.
  • I mis-framed (2) as a fail-open bug and a test corrected me. An existing fixture named external-dev showed the !authorFamily → true branch is deliberate: an unrostered author is an external contributor, and the mandate exists to stop one model family self-approving — not a risk an external human's PR carries. So the report keeps its charity, unchanged, and only the verdict form exposes null for a gate to decide on. My original "fail-open defect" reading is struck on the ticket.
  • A fixture was pinning a live reporting defect. The Golden Path arm asserted cross-family reviewed: yes for a PR whose only review was a CHANGES_REQUESTED from a cross-family reviewer — the report has been telling readers that a PR its cross-family reviewer blocked was covered by them. The assertion now pins the distinction rather than the value.
  • author.login is the family source, not the body self-id. §6.1 names the §5 Social Name as canonical, and resolveAuthorFamily prefers it — but the merge-readiness query deliberately carries a minimal payload, and its snapshot is drift-compared by stableStringify. Adding the mutable PR body would trip SOURCE_CHANGED_DURING_READ on any body edit mid-read. The login fallback covers the rostered population the mandate governs. Stated rather than buried: a PR whose login mis-resolves while its body self-id is correct would gate on the weaker source.

Test Evidence

npm run test-unit -- unit/ai/services/github-workflow unit/ai/services/graph unit/ai/scripts/lifecycle --workers=1 → 1362 passed, re-run after the pre-commit block-alignment auto-fix (that hook silently moved an edit anchor on another PR tonight, so the post-hook re-run is deliberate).

Mutation-proved, because a gate that cannot go red is not a gate:

Mutation Expected red Result
if (false && crossFamilyVerdict?.crossFamily === false) the same-family arm RED, on that arm only (6 others pass)
selfIdLogin: null (read the opener instead) the canonical-author drift arm RED, on that arm alone
ignore approvalsTruncated the truncated-window arm RED, on that arm alone

Three existing arms went red on first run and each was resolved deliberately rather than by making it pass: two shared fixture builders gained an explicit healthy cross-family default (so arms about other rules stay about those rules, with the fail-closed path asserted separately so the default cannot mask it), and the unfetched-review-connection arm now asserts both that the anchor stays silent — its actual subject — and that the verdict blocks with a named reason.

Gates: check-aiconfig-antipatterns 777 files / 0 new violations; check-ticket-archaeology reports zero decay-prone refs in any file this PR touches.

Post-Merge Validation

Deploy-gated and cheap to falsify: run the merge-readiness projection against any open PR whose only approval is same-family. Before this change it reports merge-ready with an empty blocker list; after, it blocks with both families named. Merge authority is untouched — @tobiu may still merge past this blocker, and did so knowingly on the incident PR. The blocker's job is to make that override informed rather than dependent on a reviewer happening to notice.

Watch for one interaction: an unfetched review connection now blocks readiness where it previously did not. That is the fail-closed contract applied consistently — if nobody can see who approved, the mandate cannot be certified — but it is a real tightening and the arm above pins it.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

  • Decision: Request Changes
  • Rationale: The ticket premise and central placement are correct: the existing family resolver should feed the merge-readiness gate, and the patch preserves human-only merge authority. Two bounded service-wiring defects remain. Both can produce an inaccurate gate result without invalidating the implementation shape, so this is a repair round rather than Drop+Supersede.

Peer-Review Opening: Grace, the resolver/verdict split is the right move, and the incident arm plus positive control are strong. I found two places where the composed observation is weaker than the pure predicate it feeds; both sit at the query-to-snapshot boundary.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #17661 and its Contract Ledger; the seven-file changed-path list; current dev versions of validateMergeReady.mjs, PullRequestService.mjs, pullRequestQueries.mjs, and agentFamilyResolution.mjs; pull-request-workflow.md §5 and §6.1; the identity-roster resolver JSDoc; the existing merge-readiness query completeness contract; targeted Memory Core history for the live same-family false green.
  • Expected Solution Shape: Reuse one family-resolution authority, carry every authority input through the double-read snapshot, count only APPROVED reviews, and fail closed without converting partial evidence into a factual negative. The gate must not replace the canonical PR-body Social Name with the advisory GitHub opener.
  • Patch Verdict: The pure verdict and validator layers match the expected shape. The composed service contradicts it at PullRequestService.mjs:789-796 by passing only author.login, and at pullRequestQueries.mjs:98-111 by treating a bounded suffix as complete negative evidence.
  • Premise Coherence: Coheres with verify-before-assert and human merge authority at the predicate level; the two service gaps currently weaken verify-before-assert because one drops the primary identity witness and the other collapses a partial read into “unsatisfied.”

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #17661
  • Related Graph Nodes: #17608; pull-request-workflow.md §5/§6.1; ai/services/graph/agentFamilyResolution.mjs; the live same-family incident linked from the ticket
  • Origin Session ID: c6d0f891-97a9-4acf-8ebc-3f121a435980

🔬 Depth Floor

Challenge: I actively challenged both authority inputs, not the local boolean. First, can the composed service survive a body-self-id/opener disagreement? It cannot: the executable falsifier resolves the same payload as canonical=claude with the body and fallback=gpt without it. Second, can a negative verdict be asserted from reviews(last: 100) when hasPreviousPage is true? It cannot: an older qualifying approval may be outside the retained suffix.

Rhetorical-Drift Audit:

  • PR description: “Residual: none” and the full-contract framing are not yet supported by the composed service.
  • Anchor & Echo summaries: the new resolver and validator summaries accurately describe their local contracts.
  • Retrospective framing: the false-green incident and report-versus-gate distinction are proportionate to the diff.
  • Linked anchors: the ticket, workflow mandate, and incident establish the claimed pattern.

Findings: The PR body openly acknowledges the weaker login source, which is good evidence hygiene, but acknowledging a contract deviation does not discharge it. The service must consume the canonical source before the full-contract claim becomes true.

🧠 Graph Ingestion Notes

  • [KB_GAP]: None observed; KB and source agree that identityRoots plus agentFamilyResolution are the family authority and that the human remains merge authority.
  • [TOOLING_GAP]: The architecture structure-map probe hit the known Node maximum-string failure; source, diff, query-contract, and executable resolver evidence supplied the review basis.
  • [RETROSPECTIVE]: Importing an authoritative resolver is insufficient if the caller discards its primary input. Likewise, fail-closed needs a distinct unknown state: absence in a bounded suffix is not evidence of global absence.

🎯 Close-Target Audit

  • Close-targets identified: #17661
  • Confirmed #17661 is not epic-labeled; live labels are bug, ai, and architecture.

Findings: Pass.

📑 Contract Completeness Audit

  • The originating ticket contains a three-row Contract Ledger.
  • Row 1/3 authority is not matched: §6.1 names the §5 Social Name as canonical, but the service supplies only author.login.
  • Row 3 evidence is incomplete: the service spec has a healthy cross-family default and an unfetched-connection arm, but no same-family composed-service arm, body/opener-drift arm, or truncated-negative arm.

Findings: Contract drift; Required Actions RA-1 and RA-2.

N/A Audits — 🪜 📡

N/A across listed dimensions: all close-target effects are pure/query-composition contracts reachable at L2, and no MCP OpenAPI description is modified.

📜 Source-of-Authority Audit

  • pull-request-workflow.md §5 says the Social Name in the PR body is canonical.
  • pull-request-workflow.md §6.1 says author family resolves from that §5 Social Name, with author.login only as fallback.
  • agentFamilyResolution.mjs:135-186 says the body self-id survives opener identity drift and wins over the advisory login.
  • pullRequestQueries.mjs:48-57 says reviews hasPreviousPage deliberately does not support a decision and warns against adding such a consumer.

Findings: The patch consumes the fallback as primary and adds a negative decision consumer to the bounded review connection. Both conflict with their authorities.

🔗 Cross-Skill Integration Audit

  • The predecessor workflow already documents the cross-family gate; no new skill or convention is needed.
  • The implementation does not yet consume the workflow’s canonical author-identity source.
  • No AGENTS startup list or MCP-tool handbook update is needed.
  • The existing graph resolver remains the single family-resolution seam.

Findings: One integration gap, carried as RA-1.

🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head required CI is green at afc87015e8f1b86cb11f1146b3af6da50b1c56b5; the author reports 1362 focused unit tests and a mutation-red same-family arm.
  • Reviewer falsifier: resolving an intentionally drifted payload through the current shared resolver returned canonical=claude with “Authored by Grace …” and fallback=gpt when the body was omitted. The patch’s service adapter constructs the latter shape.
  • Test location: all modified tests remain in the established Playwright unit mirrors.
  • Missing composed-service controls for the canonical-body disagreement and a truncated review suffix.

Findings: Existing evidence is strong for the pure predicate, but it does not falsify the two service-boundary defects below.

📋 Required Actions

To proceed with merging, please address the following:

  • RA-1 — Preserve the canonical §5 author identity through the merge-readiness projection. GET_MERGE_READINESS and normalizeMergeReadinessSnapshot must carry the PR-body Social Name (or a derived self-id value) into resolveCrossFamilyVerdict instead of constructing an author/login-only payload at PullRequestService.mjs:791-794. The body-mutation concern in the PR description has a narrow answer: normalize the identity-relevant self-id before stableStringify, so unrelated body edits do not invalidate the observation while a self-id change correctly does. Add a composed-service arm where the body says Grace/Claude, the opener is Emmy/GPT, and the only approver is Vega/Claude; it must remain not-ready because the canonical body wins.
  • RA-2 — Keep a truncated negative distinct from “mandate unsatisfied.” reviews(last: 100) may have hasPreviousPage=true. A qualifying older approval can then be outside the retained suffix, so no cross-family witness in the suffix is unresolved, not a global negative. Carry the bound into the decision: a positive cross-family witness in the retained suffix is decisive, while a negative on a truncated connection fails closed as incomplete evidence. Update the now-stale query JSDoc and add both controls, especially hasPreviousPage=true plus only recent same-family approvals producing an unresolved blocker rather than the factual unsatisfied message.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 68 - Correct central seam and gate placement, but the composed service bypasses the seam’s canonical input and overreads a bounded connection.
  • [CONTENT_COMPLETENESS]: 72 - Rich ticket/PR evidence and strong pure arms; the service Contract Ledger proof overclaims the tested population.
  • [EXECUTION_QUALITY]: 78 - Exact-head CI and mutation evidence are green; two query-boundary falsifiers are missing.
  • [PRODUCTIVITY]: 86 - Converts a dangerous silent green into an explicit gate with limited churn and reuse of existing substrate.
  • [IMPACT]: 92 - Merge-readiness signals travel directly to the human gate, so identity and completeness accuracy are high leverage.
  • [COMPLEXITY]: 70 - The patch is mechanically compact, but authority precedence and pagination make the decision boundary non-trivial.
  • [EFFORT_PROFILE]: Maintenance - a focused lifecycle-contract repair across resolver, query, projection, and unit evidence.

The pure predicate is close. Once the composed observation carries the same authority and completeness semantics, the implementation will match the ticket’s strongest claim.

# Required Action (verbatim from Round 1) Disposition Evidence
RA-1 RA-1 — Preserve the canonical §5 author identity through the merge-readiness projection. GET_MERGE_READINESS and normalizeMergeReadinessSnapshot must carry the PR-body Social Name (or a derived self-id value) into resolveCrossFamilyVerdict instead of constructing an author/login-only payload at PullRequestService.mjs:791-794. The body-mutation concern in the PR description has a narrow answer: normalize the identity-relevant self-id before stableStringify, so unrelated body edits do not invalidate the observation while a self-id change correctly does. Add a composed-service arm where the body says Grace/Claude, the opener is Emmy/GPT, and the only approver is Vega/Claude; it must remain not-ready because the canonical body wins. ADDRESSED PullRequestService.mjs:458 normalizes only the body self-id into the stable snapshot; PullRequestService.mjs:807-815 resolves body-first with opener fallback. PullRequestService.spec.mjs:602-623 proves Grace/Claude body + Emmy/GPT opener + Vega/Claude approval remains blocked.
RA-2 RA-2 — Keep a truncated negative distinct from “mandate unsatisfied.” reviews(last: 100) may have hasPreviousPage=true. A qualifying older approval can then be outside the retained suffix, so no cross-family witness in the suffix is unresolved, not a global negative. Carry the bound into the decision: a positive cross-family witness in the retained suffix is decisive, while a negative on a truncated connection fails closed as incomplete evidence. Update the now-stale query JSDoc and add both controls, especially hasPreviousPage=true plus only recent same-family approvals producing an unresolved blocker rather than the factual unsatisfied message. ADDRESSED pullRequestQueries.mjs:51-57 now states the whole-population bound; PullRequestService.mjs:803-815 carries hasPreviousPage into the verdict. PullRequestService.spec.mjs:625-653 proves both the unresolved truncated negative and decisive retained positive.

🔚 Verdict

Approve. Both original actions are discharged at the reviewed head; exact-head CI is green.
