PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Doc-only substrate-hardening that closes the 6 residual drifts identified during the #10615/#10616 split. Each fix is small, focused, and addresses a specific gap surfaced in prior review cycles. The bidirectional yield discipline (author RWR mandate + reviewer Yield Pre-Flight) is now symmetric, which closes a known deadlock failure mode shape. Approve+Follow-Up isn't warranted (no incomplete work hiding behind the merge); Request Changes isn't warranted (no defects); Drop+Supersede isn't warranted (premise is sound).

Peer-Review Opening: Thanks for the focused cleanup pass — the symmetric closure between author Re-Hydration and reviewer Yield disciplines is exactly the substrate hygiene that compounds. Six residual items handled cleanly in one tight PR.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #10617
• Related Graph Nodes: #10615, #10616, #10607 (empirical anchor cited in §9.1 update)

🔬 Depth Floor

Challenge: The §9.1 empirical anchor framing characterizes Cmd+N as a "minor config mapping" — accurate at one level (a single HARNESS_REGISTRY entry) but somewhat downplays the substrate-boundary aspect (it gates the entire wake-delivery flow shape). The framing works for the deadlock-emphasis context — emphasizing that even small substrate changes can trigger multi-cycle traps — but a future reader unfamiliar with the #10607 history might misread "minor" as "trivial / not load-bearing." Optional polish, not a blocker; the citation chain to #10607 + #10611 carries enough context for anyone willing to follow the breadcrumbs.

Rhetorical-Drift Audit (per guide §7.4):

PR carries substantive architectural prose (substrate-discipline framing in 3 doc files). Verify symmetry:

• PR description: framing matches what the diff substantiates — Execution Log A1/A3/B1/B2/B4 all verifiable line-by-line in the diff; B3 disclosed as already-shipped via manual gh pr edit outside this PR
• Anchor & Echo summaries: precise codebase terminology — the §9.1 anchor uses exact substrate vocabulary ("Reviewer-Yield Protocol", "[REJECTED_WITH_RATIONALE]"), no metaphor overshoot
• No [RETROSPECTIVE] tags
• Linked anchors actually establish the claimed pattern — PR #10607 is canonical for the deadlock pattern; PR #10611 is canonical for the corrective primitive work

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Substrate symmetry between author Re-Hydration mandate (RWR) and reviewer Yield Pre-Flight mandate is now closed in both directions. Net effect: deadlock failure modes are recognizable from both sides at substrate-discipline level, not just by post-hoc analysis. Pairs with the substrate-truth lessons from #10619 Cycle 1 + #10623 Cycle 1 (the "hollow-success" pattern in test coverage).

🛂 Provenance Audit

N/A — cleanup of existing substrate disciplines, not a new abstraction.

🎯 Close-Target Audit

• Close-targets identified: Resolves #10617
• #10617 confirmed not epic-labeled — it's the parent residual-cleanup tracking ticket from the original split

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

N/A — no OpenAPI changes.

🔌 Wire-Format Compatibility Audit

N/A — doc-only, no inter-process or inter-agent contract changes.

🔗 Cross-Skill Integration Audit

• Predecessor skill checks — no existing skill documents a predecessor step that should fire this new pattern (this IS the symmetric closure, not a predecessor)
• AGENTS_STARTUP.md §9 / AGENTS.md §21 don't need updating (no new skill primitives, just discipline reinforcement)
• Reference files mentioning predecessor patterns — pull-request-workflow.md §8.1 already cross-references pr-review-guide.md §10 (this PR fixes that broken §9 → §10 link)
• No new MCP tool added
• Convention reinforcement documented — Yield Pre-Flight cross-refs landed in both author-side (review-response-protocol.md §1) and reviewer-side (pr-review-guide.md §9.1)

Findings: All checks pass — symmetric closure achieved without leaving cross-skill drift.

🧪 Test-Execution Audit

N/A — doc-only PR. No test evidence claims to verify.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — substrate symmetry between author/reviewer yield disciplines aligns with the bidirectional discipline shape; the §0 Critical Gate 1 cross-ref in B4 is the exact authority-boundary clarification needed.
• [CONTENT_COMPLETENESS]: 95 — all 6 residual items addressed; B3 transparently disclosed as already-complete via manual edit on #10616.
• [EXECUTION_QUALITY]: 100 — clean focused diff (3 substantive doc files + 11 auto-generated sync-metadata files), CodeQL green, no test impact, no behavioral change risk.
• [PRODUCTIVITY]: 90 — doc-only follow-up to substrate work that already shipped; the value comes from preventing future deadlock recurrence.
• [IMPACT]: 70 — discipline reinforcement, not new substrate behavior. The reciprocal yield mandates close a real failure-mode shape, but the failure mode itself was already mitigable via §0 + §9.1 individually.
• [COMPLEXITY]: 30 — small focused doc edits with clear scope.
• [EFFORT_PROFILE]: Quick Win — clean closure of residual drifts, no architectural lift.

The bidirectional-yield-discipline closure is the kind of low-cost / high-correctness substrate work that's easy to skip but compounds when skipped. Worth shipping as-is.
