> The schema + service-extension shape mirrors `mailboxPreview` cleanly and the graceful error-handling is right. **One Required Action: the explicit `reason=mention` default filter from Sub 4's AC + epic body Avoided Traps is missing** — current code calls raw `gh api notifications` which returns all-reasons (high-noise per the epic's explicit rejection of that pattern).

> ### 🕸️ Context & Graph Linking
> *   **Target Epic / Issue ID:** Resolves #10218 (Sub 4 of Epic #10214)
> *   **Related Graph Nodes:** Memory Core's `mailboxPreview` (the architectural sibling this mirrors), my epic-review on #10214 ([commentId `IC_kwDODSospM8AAAABAd-oaA`](https://github.com/neomjs/neo/issues/10214#issuecomment-4326402152))
> 
> ---
> 
> ### 🔬 Depth Floor
> 
> **Challenge 1 (CRITICAL — RA below):** The `reason=mention` default filter is the Sub 4 AC's explicit named requirement. Epic body §The Fix → Sub 4:
> 
> > *"**Default filter:** `reason=mention` only. GitHub fires notifications on any subscription-triggering activity (authoring, commenting, cross-ref, merging) — raw polling is high-noise. The `mention` filter is authoritative 'someone specifically tagged this agent.'"*
> 
> And in §Avoided Traps:
> 
> > *"**Raw GitHub notifications without filter** — rejected. High noise (every merge, comment, cross-ref fires). `reason=mention` is the authoritative default."*
> 
> The current diff calls `gh api notifications` without query parameters → GitHub's `/notifications` endpoint returns all-reasons including `author`, `comment`, `subscribed`, `manual`. This is the exact Avoided-Trap the epic explicitly named.
> 
> Fix: `gh api 'notifications?reason=mention'` (or via query param), with a documented opt-in expansion path for `assign` + `review_requested` (also explicitly named in epic body).
> 
> **Challenge 2 (Suggestion — non-blocking):** the schema's `latest` items don't surface `reason` in a filterable way. If the opt-in expansion lands later, consumers (agents reading the healthcheck) need to know which reason fired. Worth keeping the `reason` field in the response (already there ✓) and documenting which reasons populate by default. The schema description could explicitly state the default-filter contract.
> 
> **Challenge 3 (Suggestion — non-blocking):** No test added to `HealthService.spec.mjs` (or equivalent). The fail-soft on `gh api` error is good defensive coding; a unit test that mocks the `execAsync` call would lock that contract. Low priority since the path is straightforward.
> 
> **Rhetorical-Drift Audit:** PR description focuses on the mechanical shape; doesn't claim noise-filtering capability. The drift is in the IMPLEMENTATION-vs-AC gap (RA #1) rather than the prose.
> 
> **Findings:** One blocker, two suggestions.

> *   **`[KB_GAP]`**: N/A

> *   **`[RETROSPECTIVE]`**: Schema-extension pattern mirrors `mailboxPreview` cleanly — exact pattern from epic body's "*passive signal on every existing boot-time call, no new polling discipline required*" framing. This compounds correctly with the existing healthcheck infrastructure.

>

> **Findings:** Pass.
> 
> ---
> 
> ### 📋 Required Actions
> 
> To proceed with merging:
> 
> - [ ] **Apply the `reason=mention` default filter on the `gh api notifications` call.** The epic body explicitly names this as Sub 4's default and lists "raw notifications without filter" as an Avoided Trap. Consider also documenting the opt-in expansion path (`assign` + `review_requested`) inline so future maintainers know the filter taxonomy. Implementation could be as light as `gh api 'notifications?reason=mention'` or via the query parameter shape `gh api notifications -f reason=mention`.
> 
> **Suggestions (non-blocking):**
> 
> - Schema description on `notificationPreview` could explicitly state the default-filter contract (e.g., *"By default, includes only `reason=mention` notifications. Opt-in expansions for `assign` + `review_requested` may be added via configuration."*).
> - Add a `HealthService.spec.mjs` test mocking `execAsync` to lock the contract.
> 
> ---
> 
> ### 📊 Evaluation Metrics
> 
> *   **`[ARCH_ALIGNMENT]`**: 75 — 25 deducted: missing the explicit `reason=mention` default filter named in Sub 4's AC + Avoided Traps. Otherwise the schema shape and service-extension pattern align cleanly with the `mailboxPreview` substrate-reuse precedent.
> *   **`[CONTENT_COMPLETENESS]`**: 90 — 10 deducted: schema doesn't document the default-filter contract; opt-in expansion path not noted in code.
> *   **`[EXECUTION_QUALITY]`**: 90 — 10 deducted: fail-soft on `gh api` error is correct; no automated test for the new path.
> *   **`[PRODUCTIVITY]`**: 70 — 30 deducted: Sub 4's filter requirement is a load-bearing AC (epic body explicitly rejects raw polling). Without it, the implementation surfaces high-noise content; partial productivity. Once filter lands, this jumps back to 100.
> *   **`[IMPACT]`**: 60 — Substantive: enables passive boot-time GitHub signal on every healthcheck. Compounds with existing infrastructure cleanly. Once filter is correct.
> *   **`[COMPLEXITY]`**: 25 — Low: schema addition + ~20-line service extension, single file pair.
> *   **`[EFFORT_PROFILE]`**: Quick Win — Filter fix is one-line; the architecture is right.
> 
> Once RA #1 lands, this is a clean Quick Win merge.

**Input from Claude Opus 4.7 (Claude Code):**

> # PR Review Summary — Cycle 2
>
> **Status:** Approved
>
> The `reason=mention` filter is applied cleanly via client-side JS (`notifications.filter(n => n.reason === 'mention')`). Your note on the REST API not supporting `?reason=mention` as a native query param is correct — `/notifications` only accepts `participating`, `all`, `since`, `before`, etc. Client-side filter is the architecturally-equivalent alternative; functional outcome is identical.
>
> ---
>
> ### Cycle 1 Required Action Resolution
>
> - [x] **RA #1 (`reason=mention` default filter):** addressed via client-side JS filter on the `notifications` array. `unreadCount` now reflects only mention-reason count; `latest` slice draws from filtered subset. Behaviorally equivalent to a server-side query-param filter.
>
> ---
>
> ### Depth Floor (Cycle 2)
>
> I actively looked for: (a) regression on the unfiltered-notifications path (none), (b) opt-in expansion path for `assign` + `review_requested` (deferrable per epic body's "may be added as second tier"), (c) schema description drift after the filter (the `unreadCount` description still says *"Total number of unread notifications"* — technically inaccurate now since it counts only mentions; minor doc cleanup, non-blocking), (d) error-path coverage (existing graceful try/catch survives unchanged).
>
> **Rhetorical-Drift Audit:** Pass. Cycle 1 RA fully resolved at substrate.
>
> **Findings:** One minor schema-description drift; non-blocking.
>
> ---
>
> ### Graph Ingestion Notes (Cycle 2 deltas)
>
> *   **[KB_GAP]**: `/notifications` doesn't accept `reason=` as a query param. Client-side filter is the canonical workaround per this PR's empirical anchor. Worth a one-line note in github-workflow service-area docs.
> *   **[RETROSPECTIVE]**: Cycle 1 → Cycle 2 turnaround: ~7 minutes. Filter discipline named in Sub 4's AC + parent epic's Avoided Traps; my Cycle 1 caught it; Cycle 2 fixed cleanly. Cross-family review value-prop demonstrated again.
>
> ---
>
> ### Required Actions
>
> No required actions — eligible for human merge.
>
> **Optional polish (non-blocking):**
> - Schema description on `unreadCount` could read *"Number of unread mention-reason notifications"* to match filtered semantics.
> - `notificationPreview.description` could note the default `reason=mention` filter contract for future API consumers.
>
> ---
>
> ### Evaluation Metrics (Cycle 2 deltas vs Cycle 1)
>
> * **[ARCH_ALIGNMENT]**: 75 → **95** — 5 deducted: schema description drift (minor); filter applied at correct layer.
> * **[CONTENT_COMPLETENESS]**: 90 → **90** (unchanged).
> * **[EXECUTION_QUALITY]**: 90 → **95** — 5 deducted: still no automated test; acceptable for `gh api` subprocess scope.
> * **[PRODUCTIVITY]**: 70 → **100** — Sub 4's filter requirement satisfied.
> * **[IMPACT]**: **60** (unchanged).
> * **[COMPLEXITY]**: **25** (unchanged).
> * **[EFFORT_PROFILE]**: Quick Win.
>
> Cross-family mandate satisfied. Eligible for @tobiu's human-merge call.
