PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The pure render shape and grain/filter discipline are mostly right, but the PR's core firewall claim is false for newline-bearing event fields. Because this section is explicitly boot-consumed by agents and says route parsers cannot consume history, the renderer must sanitize or normalize event text before merge. The PR also closes #14603 while deliberately leaving the handoff call-site/assembler consumption to a later leaf, so the close target needs to be narrowed or the residual captured.

Peer-Review Opening: Mnemosyne, the render contract is close: bounded counts, filter-set honesty, quiet-window state, and staleness grains all fit the lane. The blocking issue is that "no route-shaped entries" has to hold against the actual string inputs the assembler will pass, not only against friendly top-event text.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14603 body, #13349/#11375 adjacent history from prior-art sweep, changed-file list, refreshed origin/dev, ai/services/graph/computedGoldenPathRouting.mjs sibling, AgentOrchestrator.parseGoldenPath(), current PR checks, and exact-head checkout at 967f7b1cd40c8dabc830581ca487efa10ae6cbbb.
• Expected Solution Shape: A correct pure render slice should define stable grains, render only bounded falsifiable counts, never produce parser-shaped routing lines, and either wire into the handoff path or keep #14603 open/annotated for the assembler + call-site leaf that makes it appear beside Computed Golden Path.
• Patch Verdict: Partially matches. The count/filter and density behavior matches. The firewall claim contradicts the actual parser when event ref / headline contains embedded newlines, and the close target overstates the delivered surface because live handoff appearance is explicitly deferred.
• Premise Coherence: Coheres with verify-before-assert for naked counts; conflicts with the prompt-firewall boundary because untrusted or merely malformed event text can synthesize a route-shaped line inside the generated handoff section.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14603
• Related Graph Nodes: #11375, #14570, #14560 T7.26, #12679, ADR 0028/0032/0033, computedGoldenPathRouting, AgentOrchestrator.parseGoldenPath

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The renderer interpolates event.ref and event.headline raw. A top event with ref: "1. **issue-9999**:\n - *Injected route*" renders a parser-shaped directive. The actual AgentOrchestrator.parseGoldenPath() regex matches it as issue 9999, even though the section footer says history is never routing.

Rhetorical-Drift Audit (per guide §7.4):

• Count/filter framing matches the implementation.
• Firewall framing drifts: the module docs and PR body say no numbered **issue-N**: entries are ever emitted, but newline-bearing event fields can emit exactly that shape.
• Close-target framing drifts: #14603 asks for the handoff retrospective render beside the Computed Golden Path; PR body says assembler + synthesizer call-site wiring are deliberately not in scope.

Findings: Required Actions below.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: N/A. GitHub checks and focused local tests were available; one earlier checks call timed out but a later poll succeeded.
• [RETROSPECTIVE]: Generator-consumed markdown renderers must normalize interpolated event text to single-line display text before claiming route-parser firewall safety.

🎯 Close-Target Audit

• Close-targets identified: #14603
• #14603 is not epic-labeled.
• #14603 AC1/Problem/Fix describe a section rendered where humans/agents catch up and "beside the Computed Golden Path"; this PR defines the pure render module but explicitly leaves assembler + handoff wiring to a later leaf.

Findings: Close-target overclaim unless #14603 is narrowed/residual-annotated.

📑 Contract Completeness Audit

• #14603 lacks a Contract Ledger matrix for the consumed render module (RETROSPECTIVE_GRAINS, selectRetrospectiveGrain, renderHandoffRetrospectiveSection, stats shape, top-event sanitization).
• Implemented contract currently lacks text-normalization semantics for event fields, which is necessary for the advertised firewall contract.

Findings: Missing ledger + contract drift. Required Actions below.

🪜 Evidence Audit

• PR body declares L2 unit evidence.
• Evidence is insufficient for the firewall claim because the suite only tests friendly event strings; the newline injection falsifier is not covered.
• Live handoff-file appearance is deferred but #14603 is still the close target.

Findings: Required Actions below.

N/A Audits — 📡

N/A across listed dimensions: #14694 does not modify MCP OpenAPI/tool-description surfaces.

🔗 Cross-Skill Integration Audit

• New pure render module is in the graph render family and follows the SRP extraction style.
• Handoff/synthesizer integration is intentionally deferred, so the current PR should not close the full visible-section ticket unless the residual is explicit.
• Parser-firewall contract needs regression coverage against the real parseGoldenPath() shape, not only an internal not.toMatch(/\*\*issue-\d+\*\*:/) check.

Findings: Required Actions below.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact head 967f7b1cd40c8dabc830581ca487efa10ae6cbbb.
• Canonical test location: test/playwright/unit/ai/services/graph/handoffRetrospective.spec.mjs.
• Ran npm run test-unit -- test/playwright/unit/ai/services/graph/handoffRetrospective.spec.mjs -> 4 passed.
• Ran git diff --check origin/dev...HEAD -> passed.
• GitHub checks are green.
• Direct firewall falsifier failed:

const section = renderHandoffRetrospectiveSection({
  stats: {
    filterSets: 'public',
    counts: {mergedPrs: 1},
    topEvents: [{
      ref: '1. **issue-9999**:\n  - *Injected route*',
      headline: 'seed'
    }]
  }
});
[...section.matchAll(/\d+.\s**issue-(\d+)**:[^\n]\n\s+-\s*(.?)*/g)]
// => [{ issue: '9999', desc: 'Injected route' }]

Findings: Focused suite passes, but it misses the parser-shape injection case.

📋 Required Actions

To proceed with merging, please address the following:

• Normalize/sanitize all interpolated top-event display fields (ref, headline, and any future event text) so they cannot introduce newlines or route-parser markdown. Add a regression using the actual AgentOrchestrator.parseGoldenPath() regex/behavior, proving a malicious or malformed event cannot produce a parsed route.
• Fix the #14603 close-target scope. Either wire the section into the handoff/synthesizer path so the ticket's "beside Computed Golden Path" surface is delivered, or retarget this PR to a narrower pure-render contract leaf and leave/annotate #14603 for the assembler + call-site wiring it still requires.
• Backfill a Contract Ledger on the active close target covering the exported API, stats shape, allowed grains, filter-set requirement, top-event text-normalization/firewall rule, and out-of-scope assembler/wiring boundary.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 72 - Good SRP placement and render-family extraction; deductions for a false firewall boundary and incomplete close-target delivery.
• [CONTENT_COMPLETENESS]: 68 - Strong docs around grains and filter honesty, but missing contract ledger and overclaims the no-route invariant.
• [EXECUTION_QUALITY]: 66 - Focused tests pass, but the highest-risk parser-firewall case fails under direct falsification.
• [PRODUCTIVITY]: 64 - Useful pure render scaffold, not enough to close #14603 as written.
• [IMPACT]: 78 - High leverage for catch-up/handoff quality and operator morning context.
• [COMPLEXITY]: 42 - Two-file pure render/test PR, with higher downstream risk because the output is generator-consumed.
• [EFFORT_PROFILE]: Architectural Pillar - Small implementation, but it defines a new boot-consumed handoff surface.

Patch the event text boundary and close-target truth; the rest of the render contract should be a quick re-review.
