PR Review Summary

Status: Approved

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This is a narrow, operator-directed fact update across the declared identity mirror surfaces. The temporary-window decay risk is covered by #13039, the schema follow-up is separated into #13041, and the diff does not alter routing, quorum, handle, or subscription semantics.

Peer-Review Opening: I reviewed PR #13040 at exact head dc318049fc4b820b3f75d85978afc1eafc5a63d2 as the requested cross-family reviewer.

Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #13038 close target, #13039 window-end follow-up, #13041 structured-field follow-up, #12531/#12599 fact-update precedent, changed-file list, current PR checks, official Anthropic models overview, and local checkout at head dc318049fc4b820b3f75d85978afc1eafc5a63d2.
• Expected Solution Shape: A correct temporary model-assignment fact update should change only the declared mirror surfaces, keep @neo-opus-ada identity/routing stable, single-source capability values from §neo_fable, preserve subscriptionTemplate and participationStatus, and leave a dated reversion/extension path. It must not invent a new schema field cycle-1 or make Fable 5 a permanent assignment without post-window evidence.
• Patch Verdict: Matches. The diff touches README, identityRoots.mjs, ModelStats.md, and MemoryCoreMcpAuth.md; subscriptionTemplate/participationStatus remain unchanged; #13039 is natively blockedBy #13038; #13041 holds the structured modelAssignment schema follow-up.

• Related Graph Nodes: #13039, #13041, #12531, PR #12599, ADR 0012, ADR 0018, @neo-opus-ada, §neo_opus, §neo_fable

Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively checked the three drift-prone edges: whether stale @neo-opus-ada Opus-4.8 assertions remain outside intentional baseline annotations; whether the temporary window has a native decay-mitigation relationship; and whether the source values still match Anthropic's current model docs. No blocker surfaced.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: accurately frames a temporary fact-update, not a rename or behavior/routing change.
• Anchor & Echo summaries/comments: identityRoots comment names operator authority, window, baseline, and invariant; it does not claim a permanent model assignment.
• [RETROSPECTIVE] tag: N/A; none present.
• Linked anchors: #12531/#12599 establish the same fact-update surface family; #13039 and #13041 exist as the decay/schema follow-ups described.

Findings: Pass.

Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None. The only limitation was that gh issue view does not expose issue dependency fields; read-only GraphQL verified #13039.blockedBy -> #13038.
• [RETROSPECTIVE]: Temporary model assignments need two artifacts: a truthful now-record and a dated decay-mitigation ticket. #13040/#13039 is the right split; #13041 is the correct place for graph-queryable structure.

Close-Target Audit

• Close-target identified: PR body and commit subject target #13038.
• #13038 labels are documentation, enhancement, ai; confirmed not epic-labeled.
• #13039/#13041 are related follow-ups, not close-targets.

Findings: Pass.

Contract Completeness Audit

• #13038 contains a Contract Ledger for the four target surfaces.
• Implemented diff matches the ledger: identityRoots.mjs @neo-opus-ada values, ModelStats §neo_opus + update history/date, README roster row, and MemoryCoreMcpAuth binding row.
• #13039 exists and is natively blocked by #13038, satisfying the window-end decay-mitigation AC.

Findings: Pass.

Evidence Audit

• PR body declares Evidence: L2 (targeted unit spec 6/6 green + repo-wide stale-fact sweep) -> L2 required.
• Achieved evidence matches the file-state ACs: targeted identityRoots spec passes, official docs/source sweep corroborates the copied §neo_fable values, and stale-current-fact grep returns only intentional baseline/window annotations.
• Residual is correctly listed: post-merge graph re-seed for #13038.

Findings: Pass.

Provenance Audit

Internal provenance is coherent: operator directive -> #13038 fact-update ticket -> Ada/Fable coordination -> four-surface implementation. External capability values are not re-derived from memory: Anthropic's current models overview confirms claude-fable-5, 1M context, 128k max output, $10/$50 per MTok pricing, adaptive thinking always on, and GA beginning June 9, 2026: https://platform.claude.com/docs/en/about-claude/models/overview

Source-of-Authority Audit

The PR cites operator authority for the temporary assignment and steward authority for schema/routing questions. I verified the public substrate pieces available to reviewers: #13038 records the operator-directed window and anti-rename boundary; the PR comment records @neo-fable's three answers; #13041 carries the schema follow-up instead of landing it here; and identityRoots.mjs keeps modelFamily: 'claude' plus existing routing fields unchanged.

Cross-Skill Integration Audit

• No skill files, MCP/OpenAPI tool surfaces, AGENTS substrate, or workflow conventions are modified.
• The only future schema convention is explicitly deferred to #13041, with IdentitySchema.md named there.
• The Fleet Manager consumer relationship is captured as a future reader of modelAssignment, not duplicated in #13040.

Findings: Pass.

Test-Execution & Location Audit

• Branch checked out locally at dc318049fc4b820b3f75d85978afc1eafc5a63d2.
• Ran node --check ai/graph/identityRoots.mjs: parse OK.
• Ran UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs identityRoots: 6/6 passed.
• Ran git diff --check origin/dev...HEAD: clean.
• Ran gh pr checks 13040: Analyze, Classify test scope, CodeQL, Retired Primitives Check, integration-unified, Tree JSON lint, lint-pr-body, and unit all pass.

Findings: Pass. Final freshness read: PR is OPEN, mergedAt: null, head dc318049fc4b820b3f75d85978afc1eafc5a63d2; GitHub currently reports mergeStateStatus: UNKNOWN, so the human merge gate should let GitHub recalculate before merging.

Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 - I actively checked handle stability, modelFamily/review semantics, subscriptionTemplate stability, and schema deferral; none introduce architectural drift.
• [CONTENT_COMPLETENESS]: 100 - I actively checked the Fat Ticket ledger, PR body evidence/residuals, source references, follow-up tickets, and public mirror rows; all required surfaces are documented.
• [EXECUTION_QUALITY]: 100 - Focused parse/unit checks, diff check, CI, dependency relationship, commit author, and stale-surface sweep all passed with no observed defect.
• [PRODUCTIVITY]: 100 - The PR fully delivers #13038's transparency record while separating the window-end and schema work into #13039/#13041.
• [IMPACT]: 60 - Substantive identity-registry hygiene with Fleet Manager implications, but no runtime behavior, routing, or schema change lands in this PR.
• [COMPLEXITY]: 45 - Moderate-low: four mirror surfaces plus relationship/follow-up verification; the semantics are important but the diff is value-level.
• [EFFORT_PROFILE]: Maintenance - High-value fact consistency and decay mitigation, implemented as a narrow registry/docs update rather than a new subsystem.

Approved. Human-only merge gate applies; I will not merge.
