● # PR Review Summary

Status: Approved

LGTM. I reviewed the current head a0c43d855, pushed one tiny reviewer cleanup commit for whitespace/terminology, and revalidated the branch after that push.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This PR delivers the cross-harness prompt-landing matrix required by #10649 without bundling the separate implementation fixes. The remaining live proof belongs to the planned bridge delivery test, so it is correctly represented as post-merge validation rather than extra scope in this docs PR.

Peer-Review Opening: I reviewed this as the #10649 validation-matrix slice under the #10647 safety envelope.

Context & Graph Linking

• Target Epic / Issue ID: Resolves #10649
• Related Graph Nodes: #10647, #10601, #10644, #10645, #10650, wake prompt landing, bridge backlog isolation, harness prompt surface

Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The matrix is intentionally a runbook/evidence artifact, not proof that the next bridge restart will succeed. The important non-blocking watchpoint is that future validation must not regress into layer-local success: requirements 6-9 need prompt-surface evidence, not only A2A persistence, subscription state, or osascript exit status.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches the single-doc diff.
• Matrix language: after reviewer cleanup, requirement references and the Codex appName wording match the mechanical gate.
• [RETROSPECTIVE] tag: see below; scoped to validation discipline, not implementation completion.
• Linked anchors: #10649 is the validation-matrix ticket; #10647 is the parent safety envelope.

Findings: Pass after reviewer cleanup commit a0c43d855.

Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: Initial branch had one trailing-whitespace failure caught by git diff --check; reviewer cleanup commit a0c43d855 fixed it before approval.
• [RETROSPECTIVE]: Wake delivery must be validated as prompt-surface landing. Storage/list success, wake event emission, adapter selection, and successful adapter exit are necessary layers, but none are sufficient proof without the recipient prompt/composer effect.

Provenance Audit

Internal origin: #10649 under #10647, created from the 2026-05-03 wake/heartbeat regression analysis and session 89b259c3-27ec-4afb-baaf-fd39b55bffe1. External provenance audit is N/A; this is a repo-specific incident gate, not an imported architectural abstraction.

---

Close-Target Audit

• Close-targets identified: Resolves #10649
• #10649 labels verified: enhancement, ai, testing, architecture; not epic

Findings: Pass.

---

MCP-Tool-Description Budget Audit

N/A. The PR does not modify MCP OpenAPI descriptions.

---

Wire-Format Compatibility Audit

N/A. The PR does not alter JSON-RPC, A2A, wake-event, or bridge payload wire formats.

---

Cross-Skill Integration Audit

• Existing skill predecessor steps checked conceptually: this doc defines test evidence requirements, while #10650 owns the operational restart/re-enable protocol.
• AGENTS_STARTUP.md / AGENTS.md updates are not required for this doc-only matrix.
• No MCP tool surface or skill payload changed.
• New convention is documented in ai/docs/wake-prompt-landing-matrix.md, including when it applies and which evidence is required.

Findings: All checks pass — no integration gaps.

---

Test-Execution Audit

• Branch checked out locally via checkout_pull_request.
• Docs-only change; no framework/runtime test required.
• git diff --check origin/dev...HEAD passed after reviewer cleanup.
• GitHub checks at head a0c43d855: CodeQL and Analyze completed successfully.

Findings: Docs validation and GitHub checks pass.

Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 - 5 points deducted because the PR defines the validation discipline but the actual cross-harness proof remains a post-merge operational run; the split is correct for #10649.
• [CONTENT_COMPLETENESS]: 95 - 5 points deducted because the PR body test evidence is brief, but the document itself covers the ticket's required matrix columns, harness rows, negative assertions, backlog isolation preflight, and manual-vs-deterministic evidence split.
• [EXECUTION_QUALITY]: 95 - 5 points deducted because the initial branch had trailing whitespace and two wording nits; commit a0c43d855 fixed those and the current head is clean.
• [PRODUCTIVITY]: 100 - I checked the #10649 acceptance criteria and confirmed the current doc covers the matrix, storage-vs-delivery distinction, Claude/Antigravity/Codex rows, Antigravity file-write negative assertion, fresh-session negative assertion, manual UI evidence requirements, and backend/adapter deterministic-test expectations.
• [IMPACT]: 80 - This is a major safety gate for the wake/heartbeat restart path, but it is documentation/runbook scope rather than a core substrate implementation.
• [COMPLEXITY]: 30 - Low structural complexity: one markdown document, no runtime paths, no wire-format changes, and no MCP tool surface changes.
• [EFFORT_PROFILE]: Quick Win - High coordination value with low implementation complexity.

Closing note: the next merge gate is still human-only. This approval means the PR is eligible for @tobiu to merge after normal repository checks; it is not an instruction for any agent to run gh pr merge.
