🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Clean, additive observability that delivers exactly what #13320 asks — scenario + route evidence on Codex wake-delivery logs — with no delivery-mechanic change and pure, well-placed classifier/formatter functions. The one finding (3 of 6 classifier branches untested) is a minor coverage observation on a pure function, non-blocking and not worth a follow-up ticket. No churn risk: gated to Codex only.

Peer-Review Opening: Thanks Euclid — tidy split (pure buildWakeDeliveryEvidence classifier + formatWakeDeliveryEvidence formatter + a gated label threaded through the delivery paths) keeps the delivery mechanics untouched and the evidence Codex-scoped. This directly serves the #13287 live-validation need. One non-blocking coverage note below.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #13320 (log Codex wake scenario+route for validation; enhancement/testing/regression/ai, leaf — not epic); #13287 (Codex AFK live-validation, the consumer) + #13012 (harness epic); current dev source of deliverDigest / deliverViaCodexAppServer / deliverViaOsascriptWithRetry in ai/daemons/wake/daemon.mjs; the diff.
• Expected Solution Shape: A pure scenario-classifier + a log-label formatter, gated so only Codex/app-server delivery emits the label (no log churn for other harnesses), appended to the existing delivery log lines WITHOUT touching delivery mechanics; unit coverage for the live-validation scenarios. Must NOT hardcode message content into logs (PII) or alter retry/coalesce behavior.
• Patch Verdict: Matches. buildWakeDeliveryEvidence is pure over {messages,tasks,permissions,heartbeats} counts; formatWakeDeliveryEvidence is pure string formatting (counts only, no content → no PII); the label is gated by meta.appName === 'Codex' || adapter === CODEX_APP_SERVER_ADAPTER and merely appended to existing log lines; the same evidence is computed on the retry path (attemptDeliveryRetries) for consistency. The if/else classification ordering is correct across all count combinations (verified: pure-heartbeat / direct-message / mixed-message-heartbeat / mixed-actionable-heartbeat / actionable / empty fall through correctly). The only divergence is coverage, not direction.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #13320
• Related Graph Nodes: #13287 (live-validation consumer), #13012 (harness epic)

🔬 Depth Floor

Challenge (non-blocking): buildWakeDeliveryEvidence classifies into 6 scenarios (empty, pure-heartbeat, direct-message, mixed-message-heartbeat, mixed-actionable-heartbeat, actionable), but the spec exercises only 3 of them via daemon-integration tests — direct-message (codex-app-server + osascript), pure-heartbeat (osascript), mixed-message-heartbeat (osascript). The actionable, mixed-actionable-heartbeat, and empty branches are unverified. Because the function is module-internal (not exported), an exhaustive direct unit test of the pure classifier would require exporting it (cheaper + more complete than spinning up the daemon for tasks/permissions scenarios). This is genuinely non-blocking — the 3 covered scenarios are exactly the #13287 live-validation targets, and a misclassification in an untested branch would only mislabel a log line, never affect delivery. Worth a cheap exhaustive unit test if/when buildWakeDeliveryEvidence is exported for any other reason.

Rhetorical-Drift Audit: PR framing ("distinguish pure-heartbeat, direct-message, and mixed message+heartbeat wakes ... without changing delivery mechanics") matches the diff precisely — the scenario names are exactly the emitted labels and the delivery functions only gained an appended log string. No drift.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Threading observability evidence through an existing delivery path as a gated, content-free, mechanic-neutral log label is the right shape for live-validation instrumentation — it adds diagnostic signal without becoming a behavioral dependency.

N/A Audits — 📡 📑 🔗

N/A across listed dimensions: no openapi.yaml/MCP-tool-description change (📡); no new public/consumed contract surface — the log-label is human-read validation output, not an API (📑); no new cross-skill convention or workflow primitive — an internal daemon log format consumed by live-validation observers (🔗).

🎯 Close-Target Audit

• Close-targets identified: Resolves #13320 (verified closingIssuesReferences = [13320]); Related: #13287, Related: #13012 are non-closing extras (correct).
• #13320 confirmed not epic-labeled (enhancement/ai/testing/regression/architecture/model-experience).

Findings: Pass — single newline-isolated Resolves #13320, leaf ticket, epic refs correctly demoted to Related:.

🪜 Evidence Audit

PR body: Evidence: L2 (mock-bin dispatch across osascript/codex-app-server + full wake-daemon unit coverage) → L2 required for #13320 log observability. Residual: L4 live Codex AFK validation remains on #13287.

• Evidence: line present; achieved (L2) meets required (L2) for #13320's log-observability AC.
• The L4 live-Codex residual is correctly attributed to the separate #13287 (not this PR's close-target) and listed in ## Post-Merge Validation.
• No evidence-class collapse — the unit/mock-bin coverage is kept at L2; not promoted to a live-Codex claim.

Findings: Pass — honest L2-meets-L2 for the logging AC, live residual correctly on #13287.

🧪 Test-Execution & Location Audit

• Canonical location: daemon.spec.mjs → test/playwright/unit/ai/daemons/wake/ ✓ (per unit-test.md).
• Execution: CI ran the unit suite green on the head (this spec is under test/playwright/unit/ → covered); author evidence corroborates — daemon.spec.mjs 32/32, plus the -g "Codex|app-server" slice 5/5. I read the 4 added/modified tests: each spawns the daemon, drives the scenario (direct-message / pure-heartbeat / mixed), and asserts the exact scenario=…; route=…; adapterSource=…; counts=… line in stdout — they correctly target the new behavior and the existing delivery-match strings still resolve (the label is appended after them).
• Local re-run not stacked on top: these are daemon-spawn integration tests; per known node-unit env limits a local run risks an env-false-negative less reliable than the CI run in-env + the author's evidence.

Findings: Tests pass (CI + author evidence); location canonical; logic sound.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — clean pure-classifier + formatter split, gated injection, mechanic-neutral, consistent across deliver + retry paths. 5 deducted: the classifier is module-internal so its branches aren't directly unit-testable (minor testability seam).
• [CONTENT_COMPLETENESS]: 95 — @summary JSDoc on both new functions + the updated deliverDigest/evidenceLabel params; Fat-Ticket body with clear evidence/deltas. 5 deducted: the 6-value scenario taxonomy is implicit in the if/else rather than enumerated in one doc'd place.
• [EXECUTION_QUALITY]: 90 — CI-green + author evidence (32/32, 5/5); classification ordering verified correct; existing log-match + new assertions both hold; no mechanic change. 10 deducted: 3 of 6 classifier branches (actionable, mixed-actionable-heartbeat, empty) unverified.
• [PRODUCTIVITY]: 95 — achieves #13320's scenario+route log observability for the #13287 validation. 5 deducted: untested classifier branches.
• [IMPACT]: 45 — live-validation instrumentation for the Codex AFK wake path (#13287); a standard observability feature, not framework architecture.
• [COMPLEXITY]: 35 — Low–moderate: two pure functions plus threading one optional label through three delivery functions and the gating predicate; well-contained, no new control-flow beyond the appended label.
• [EFFORT_PROFILE]: Quick Win — high-ROI diagnostic signal at low complexity, unblocking the #13287 live route-validation.

Clean, correctly-scoped, mechanic-neutral observability — approving for the human merge gate. The untested classifier branches are a cheap future unit test, not a blocker. Nice work, Euclid.
