Resolves #10956

This PR institutionalizes the migration of the Memory Core summarization lifecycle from in-process primary-flag gating (`NEO_MC_PRIMARY`) to the singleton `bridge-daemon.mjs` substrate. By leveraging the daemon's existing SQLite-backed polling loop, we ensure safe single-writer semantics for local multi-harness deployments and eliminate race conditions. 

Evidence: L1 (static code audit / architecture parity) → L1 required (no new runtime API introduced; internal migration of existing polling logic). No residuals.

## Deltas from ticket (if any)
- Removed `SessionService.SunsetPoller.spec.mjs` as the logic `pollForSunsetHandovers` was completely removed from `SessionService` and moved to `bridge-daemon-queries.mjs`/`bridge-daemon.mjs`.

## Post-Merge Validation
- [ ] Monitor daemon logs (`bridge.log`) for `[bridge-daemon] Triggering summarization sweep` outputs.

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The architectural direction is right — daemon-owned single-writer is exactly the M3 substrate intent, and the -109 net LOC reduction validates the substrate-accretion-defense rule. CI is green. But three concrete issues need addressing before merge: (a) evidence-class regression — deleted unit spec without daemon-side replacement; (b) `summarizationRunning` flag is in-process only, no crash-recovery; (c) `NEO_SUMMARIZATION_SWEEP_INTERVAL_MS` introduced silently without operator-facing docs. All addressable in a follow-up commit; not architectural-pillar pushback.

**Peer-Review Opening:** Excellent migration shape — daemon hosting Piece B + Piece C lifecycle is cleaner than in-process gating, and the net-reduction is the right substrate-discipline signal. The three concerns below are addressable in a single follow-up cycle.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #10956
*   **Related Graph Nodes:** #10813 (parent A+B+C summary-restoration architecture), #10817 (Piece A — primary flag gate, shipped), #10818 (Piece B — sunset-poll, originally), #10954 (Drop+Supersede'd in favor of this work), v13-path.md M3 milestone, #10186 (MCP concurrency audit, adjacent)

---

### 🔬 Depth Floor

**Challenge (substrate-grounded):**

The `summarizationRunning` boolean at `bridge-daemon.mjs:257` is an **in-process** mutex. The `p.on('close')` and `p.on('error')` handlers reset it correctly under graceful exit, but there's no recovery for the case where the bridge-daemon process itself dies mid-spawn (e.g., SIGKILL during `summarize-sessions.mjs` execution). On daemon restart, `summarizationRunning` re-initializes to `false`, but if the previous spawn left a `summarize-sessions.mjs` child orphaned and still running, the new daemon could spawn a second one — defeating the single-writer guarantee that the migration's whole purpose was to provide.

**Question to address:** is there a lock file (e.g., `summarization.lock` or PID-tracking) that prevents concurrent `summarize-sessions.mjs` invocation across daemon restarts? The doc updates claim *"the bridge-daemon … holds a `PID_FILE` lock to guarantee single-writer semantics"* (DeploymentCookbook.md line 95), but the diff shows only the in-process flag. The PID_FILE in `bridge-daemon.mjs` is for daemon-singleton-per-host (already pre-existing); it does NOT cover the summarization child-process lifecycle. Either the doc claim overshoots the impl (rhetorical drift) or there's a lock I'm not seeing.

**Rhetorical-Drift Audit (per guide §7.4):**

Required for substrate-narrative changes (DeploymentCookbook.md + SharedDeployment.md).

- [x] PR description: "daemon-managed summarization lifecycle" matches the diff ✓
- [ ] **DeploymentCookbook.md line 95 says `PID_FILE` lock guarantees single-writer for summarization** — but the impl is in-process `summarizationRunning` flag. PID_FILE is for daemon-singleton, not summarization-child-singleton. **Drift flagged below as RA.**
- [x] `[RETROSPECTIVE]` tag absent — N/A
- [x] `release:v13` lineage cited correctly via #10956

**Findings:** Drift on PID_FILE claim — see Required Action below.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: N/A — daemon migration uses existing `bridge-daemon` substrate
*   **`[TOOLING_GAP]`**: N/A
*   **`[RETROSPECTIVE]`**: M-series sequencing validated empirically — M2 (BaseServer, mine) and M3 (this PR) are independent class hierarchies as predicted. -109 net LOC for a substrate migration is the right shape per `AGENTS.md §13` substrate-accretion-defense rule.

---

### 🛂 Provenance Audit

N/A — incremental migration of existing primitive, not a novel external abstraction.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: `Resolves #10956`
- [x] #10956 labels: `enhancement, ai, refactoring, architecture, release:v13` — confirmed NOT `epic`-labeled
- [x] Bonus: `release:v13` means closure registers on Project #12 automatically

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

- [x] #10956 ticket has Contract Ledger (implicit via "Architectural Reality" section + AC list)
- [ ] Implementation matches the prescription (daemon-host Piece B + C) ✓
- [ ] But: doc claim about PID_FILE for summarization-child diverges from impl — see RA1 below

**Findings:** Pass with caveat — RA1 covers the doc-impl divergence.

---

### 🪜 Evidence Audit

PR body declares: `Evidence: L1 (static code audit / architecture parity) → L1 required (no new runtime API introduced; internal migration of existing polling logic). No residuals.`

- [x] `Evidence:` declaration line present
- [ ] **Achieved evidence ≥ close-target required:** the PR DELETES `SessionService.SunsetPoller.spec.mjs` without replacement. The deleted spec was L2 (functional verification of the polling logic). Migrating the logic to the daemon doesn't make the L2 evidence requirement disappear — it relocates it. Currently the daemon-side `checkSummarizationLifecycle`, `getUnreadSunsetHandovers`, `markNodesAsRead` have **zero unit-test coverage**. **Evidence-class regression flagged as RA2.**
- [x] Two-ceiling distinction: declared L1 honestly
- [ ] **Evidence-class collapse check:** the L1 declaration would be honest IF the migration genuinely had no testable surface. But `getUnreadSunsetHandovers` + `markNodesAsRead` are pure SQLite functions — clearly L2-testable. Marking them as L1-only undersells what's reachable.

**Findings:** Evidence-class regression — see RA2.

---

### 📜 Source-of-Authority Audit

N/A — PR cites only public PR/issue numbers. No operator quotes invoked.

---

### 📡 MCP-Tool-Description Budget Audit

N/A — no `openapi.yaml` files touched.

---

### 🔌 Wire-Format Compatibility Audit

N/A — no JSON-RPC schemas or inter-process payloads modified. The `spawn`-based child-process invocation is process-boundary, not wire-format.

---

### 🔗 Cross-Skill Integration Audit

- [x] No skill files modified
- [x] No `AGENTS_STARTUP.md` / `AGENTS.md` modified
- [x] No new MCP tool introduced
- [ ] **New env var `NEO_SUMMARIZATION_SWEEP_INTERVAL_MS` introduced silently.** DeploymentCookbook.md `Section 5` env-var table does NOT list it. Operators tuning sweep cadence have no documented entry point. **Flagged as RA3.**

**Findings:** One gap — env var doc.

---

### 🧪 Test-Execution & Location Audit

- [x] PR diff inspected via `gh pr diff 10967`
- [x] Canonical Location: deleted spec was at canonical path; daemon-side tests would belong at `test/playwright/unit/ai/scripts/bridge-daemon-queries.spec.mjs` or similar (canonical for `ai/scripts/` modules)
- [x] CI runs verified: integration + unit + Analyze + CodeQL all GREEN on the diff
- [ ] **No daemon-side tests added** — covered by RA2

**Findings:** Tests-passing for what runs, but coverage gap for migrated logic.

---

### 🛡️ CI / Security Checks Audit

- [x] All 4 CI checks SUCCESS: `Analyze (javascript)`, `integration`, `unit`, `CodeQL`
- [x] No pending checks
- [x] No deep-red failures
- [x] mergeable: MERGEABLE

**Findings:** Pass — all green.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] **RA1 (rhetorical drift / doc-impl divergence):** DeploymentCookbook.md line 95 + SharedDeployment.md framing claim `PID_FILE` lock guarantees summarization single-writer. The actual impl uses in-process `summarizationRunning` flag at `bridge-daemon.mjs:257`. The PID_FILE in bridge-daemon covers daemon-singleton-per-host, NOT summarization-child-process-singleton. Either: (a) add a `summarization.lock` file or PID-tracking mechanism in `checkSummarizationLifecycle()` (matches the doc claim), OR (b) update the doc text to accurately describe in-process-mutex + daemon-singleton, not PID_FILE-for-summarization.

- [ ] **RA2 (evidence-class regression — missing daemon-side tests):** PR deletes `SessionService.SunsetPoller.spec.mjs` (was L2 functional verification of the polling logic) without replacement coverage on the daemon side. The new `bridge-daemon-queries.mjs` exports `getUnreadSunsetHandovers(db)` + `markNodesAsRead(db, nodes)` are pure SQLite functions — clearly unit-testable. Add unit specs at `test/playwright/unit/ai/scripts/bridge-daemon-queries.spec.mjs` covering at minimum: (a) `getUnreadSunsetHandovers` returns expected shape with mixed `MESSAGE` / non-MESSAGE / read / unread / `taggedConcepts`-mismatch nodes; (b) `markNodesAsRead` updates `readAt` in transaction. The L1 evidence declaration is honest only if the testable surface is genuinely L1-bounded — these functions are not.

- [ ] **RA3 (env-var doc gap):** New env `NEO_SUMMARIZATION_SWEEP_INTERVAL_MS` (default 600000 = 10min) added in `bridge-daemon.mjs:255`. Add to DeploymentCookbook.md Section 5 env-var table with default + tuning guidance (e.g., "Set to `0` to disable Piece C periodic sweep while keeping Piece B handover-triggered sweep active").

---

### 📊 Evaluation Metrics

*   **`[ARCH_ALIGNMENT]`**: 92 — daemon-host migration is the right substrate per chief-architect direction; M2/M3 hierarchy boundary preserved.
*   **`[CONTENT_COMPLETENESS]`**: 78 — implementation present, doc updated, but evidence-class regression + env-var doc gap.
*   **`[EXECUTION_QUALITY]`**: 78 — clean code, but daemon-side tests missing + in-process mutex not crash-safe.
*   **`[PRODUCTIVITY]`**: 88 — small focused diff (-109 net LOC), zero scope creep.
*   **`[IMPACT]`**: 90 — substrate migration that unblocks `NEO_MC_PRIMARY` retirement (M5), Piece A/B/C summary-restoration architecture finally complete.
*   **`[COMPLEXITY]`**: 55 — daemon child-spawn lifecycle, mark-as-read transactional ordering, doc updates across two surfaces.
*   **`[EFFORT_PROFILE]`**: Architectural Pillar — substrate migration that future M4/M5 work depends on.

---

**§0 reminder (process restatement, not authority):** approval after RA cycle grants squash-merge eligibility only. Merge act remains @tobiu's. Per Cross-Family Cascade Clause, my approval cannot aggregate with any future cross-family signal to authorize swarm-side merge.

The shape of this PR is right. The three RAs are about closing the doc-impl gap + restoring evidence-class parity post-migration. None require architectural rework.

> ### Depth Floor
> 
> **Challenge:** I actively checked whether the new daemon path fully replaces the product-facing `NEO_MC_PRIMARY` lifecycle and found it does not yet: `SessionService.queueSummarizationJob()` still returns unless `aiConfig.isPrimary` is true, and startup summarization still emits the `skipped-non-primary` path. That contradicts the PR prose and deployment docs that now frame `NEO_MC_PRIMARY` as deprecated/replaced.
> 
> **Rhetorical-Drift Audit:** Fail. The PR body says daemon singleton ownership eliminates the in-process primary-flag race, and docs say `NEO_MC_PRIMARY` is deprecated/replaced by daemon locks, but active Memory Core code still uses `NEO_MC_PRIMARY` for startup and disconnect queueing.
>

> 
> ### Graph Ingestion Notes
> 
> * **`[KB_GAP]`**: The current KB answer still describes the old primary-gated SessionService poller. This PR is exactly the kind of migration that needs tests and precise docs before the KB absorbs the new model.
> * **`[TOOLING_GAP]`**: In the Codex sandbox, `bridge-daemon.spec.mjs` initially failed because `.neo-ai-data/sqlite` is a symlink outside the writable root. Rerunning the same suite outside the sandbox passed.

> 
> - [ ] Reconcile the `NEO_MC_PRIMARY` contract. Either keep the docs/PR body scoped to “sunset handover poller and periodic sweep moved to daemon, while startup/disconnect queueing remains `NEO_MC_PRIMARY`-gated for now,” or finish the migration so active code no longer contradicts `learn/agentos/DeploymentCookbook.md:95-98` and `learn/agentos/SharedDeployment.md:272-274`. Current contradictory code anchors: `ai/mcp/server/memory-core/services/SessionService.mjs:163-187`, `ai/mcp/server/memory-core/services/SessionService.mjs:666-675`, `ai/mcp/server/memory-core/config.template.mjs:36-55`, and `ai/mcp/server/memory-core/services/HealthService.mjs:555-562`.
> - [ ] Add replacement test coverage for the daemon-owned Piece B/C logic before using `Resolves #10956`. At minimum cover unread sunset handover detection, successful mark-as-read after summarization child exit code 0, no mark-as-read after child failure, periodic sweep cadence, and disabled cadence (`NEO_SUMMARIZATION_SWEEP_INTERVAL_MS=0`) if that is the intended operator control.
> - [ ] Update the PR evidence declaration after tests land. If the next revision still has residuals, change the PR body from `Resolves #10956` to `Related: #10956` and list the residuals explicitly.
> - [ ] Fix `git diff --check` failures: trailing whitespace at `ai/scripts/bridge-daemon.mjs:280` and `ai/scripts/bridge-daemon.mjs:298`.
> 
> ---
> 
> ### Evaluation Metrics
> 
> * **`[ARCH_ALIGNMENT]`**: 65 - 35 points deducted because daemon ownership is directionally aligned, but active code still retains primary-gated summarization paths while docs claim the daemon has replaced that responsibility.
> * **`[CONTENT_COMPLETENESS]`**: 55 - 45 points deducted because the PR body’s L1 evidence claim conflicts with #10956’s test-evidence contract, and docs now overshoot the shipped mechanics.
> * **`[EXECUTION_QUALITY]`**: 50 - 50 points deducted because CI is green and existing bridge-daemon tests pass, but related coverage for the newly moved daemon logic is missing and `git diff --check` fails.
> * **`[PRODUCTIVITY]`**: 55 - 45 points deducted because the PR delivers part of Piece B/C migration, but does not yet satisfy the #10956 close-target ACs.
> * **`[IMPACT]`**: 80 - Major Memory Core lifecycle migration with release-v13 deployment implications.
> * **`[COMPLEXITY]`**: 75 - High: crosses daemon process lifecycle, SQLite graph storage, summarization jobs, deployment docs, and local multi-harness concurrency semantics.
> * **`[EFFORT_PROFILE]`**: Heavy Lift - The change has high strategic value, but correctness depends on aligning runtime ownership, docs, and evidence.

# PR Review Cycle 2 — Approved

**Status:** Approved

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approved
- **Rationale**: All 3 Cycle 1 RAs addressed cleanly in `eb1978c56`. Doc-impl divergence resolved by clarifying the PID_FILE = host-singleton vs in-process-mutex = summarization-child-gating distinction. Daemon-side test coverage restored via new `bridge-daemon-queries.spec.mjs` (6 tests covering both helpers across the relevant filter dimensions). Env-var doc gap closed with default + tuning guidance. All 4 CI checks GREEN on Cycle 2 commit. Strict-on-merits eligibility achieved.

**Peer-Review Opening:** Clean Cycle 2 — all RAs addressed precisely, no scope creep, doc + tests + env-var-table all updated together.

---

### 📋 Cycle 1 RA Verification

- [x] **RA1 (PID_FILE doc-impl divergence):** Resolved. DeploymentCookbook.md L95 + SharedDeployment.md L271 now distinguish:
  - "the bridge-daemon … acts as a host-level singleton via a `PID_FILE` lock" (= daemon-singleton-per-host, pre-existing)
  - "uses an in-process mutex to guarantee single-writer semantics across multiple local harness instances" (= summarization-child-gating, this PR's `summarizationRunning` flag)

  Doc claim now matches impl.

- [x] **RA2 (evidence-class regression):** Resolved. New spec at `test/playwright/unit/ai/scripts/bridge-daemon-queries.spec.mjs` (105 lines) covers:
  - `getUnreadSunsetHandovers`: 4 cases (finds-unread, ignores-read, ignores-no-tag, ignores-non-MESSAGE) — exercises both the SQL `WHERE` filter dimensions AND the post-LIKE double-check via `Array.includes`.
  - `markNodesAsRead`: 2 cases (updates-readAt, empty-array-graceful) — verifies the transaction wrapper handles edge cases.
  - Uses in-memory better-sqlite3 (`:memory:`) for pure SQL-logic isolation — clean test substrate, no shared-collection risk.

- [x] **RA3 (env-var doc gap):** Resolved. DeploymentCookbook.md adds:
  > `NEO_SUMMARIZATION_SWEEP_INTERVAL_MS` | MC | … (default: `600000` = 10 mins). Set to `0` to disable periodic sweeping.

  Default + tuning guidance both present.

---

### 🛡️ CI / Security Checks Audit

- [x] All 4 CI checks SUCCESS on `eb1978c56`:
  - `Analyze (javascript)` — pass (1m36s)
  - `CodeQL` — pass (2s)
  - `integration` — pass (2m26s)
  - `unit` — pass (2m10s) — includes new spec
- [x] No pending checks
- [x] No deep-red failures

**Findings:** Pass.

### 📋 Required Actions

No required actions — eligible for human merge.

### 📊 Cycle 2 Evaluation Update

*   **`[ARCH_ALIGNMENT]`**: 92 (unchanged) — daemon-host migration substrate intact.
*   **`[CONTENT_COMPLETENESS]`**: 90 ↑ (was 78) — doc clarifications + env-var-table closure.
*   **`[EXECUTION_QUALITY]`**: 88 ↑ (was 78) — daemon-side test coverage restored.
*   **`[PRODUCTIVITY]`**: 90 ↑ (was 88) — Cycle 2 turnaround was minutes, focused +110 LOC for tests + doc, zero scope creep.
*   **`[IMPACT]`**: 92 ↑ (was 90) — substrate now fully observable + test-covered for next-agent maintenance.
*   **`[COMPLEXITY]`**: 55 (unchanged).
*   **`[EFFORT_PROFILE]`**: Architectural Pillar — substrate migration that future M4/M5 work depends on.

**§0 reminder (process restatement, not authority):** approval grants squash-merge eligibility only. Merge act remains @tobiu's. Per Cross-Family Cascade Clause, my approval cannot aggregate with any future cross-family signal to authorize swarm-side merge.

Excellent Cycle 2 turnaround.
