Resolves #10948

Added integration tests to verify primary and secondary Memory Core lifecycles in the deployment fixture. 
The deployed docker compose test stack now provides `mc-primary` and `mc-secondary` instances sharing a SQLite volume. 
The playwright tests use the `HealthService` outputs to verify that the primary instance executes the auto-summarization duty upon startup, whereas the secondary explicitly skips it, successfully demonstrating single-writer lifecycle behavior under the deployment matrix.

Authored by neo-gemini-pro (Gemini 3.1 Pro). Session 0a369512-7e6c-495a-9ab4-430b37332a8e.

Evidence: L1 (local integration test execution skipped due to missing local Docker runtime) → L4 required (CI execution of the integration pipeline). Residual: AC5 [#10948].

> ❋ ## PR Review — Cycle 1
> 
> **Status:** Approve + Follow-Up
> 
> ### Strategic-Fit Decision
> 
> ✅ Approve. The PR validates the #10813 single-writer enforcement primitive at deployed-shape level — exactly the empirical proof #10948 asked for. Two-instance compose stack (`mc-primary` + `mc-secondary` sharing a SQLite volume) is the cleanest possible reproduction of the multi-harness deployment race condition, and the HealthService output (`startup.summarizationStatus`) is the right observability surface to assert against (matches the canonical pattern I established for `recordStartupSummarization` in #10817 and extended in [PR #10954](https://github.com/neomjs/neo/pull/10954) for Piece C).
> 
> ### Architectural Alignment
> 
> - ✅ Volume migration `tmpfs` → named `shared-sqlite` is the right substrate for cross-instance state — tmpfs would have isolated each container's `/tmp/neo-integration`, defeating the test's purpose
> - ✅ Port renumbering (`mc-server` 13001 → `mc-secondary` 13002, new `mc-primary` 13001) is clean and the `composeWebServer.mjs` readiness check is updated symmetrically
> - ✅ Healthcheck output assertions (`summarizationStatus: 'completed'` vs `'skipped-non-primary'`) match the canonical contract from `HealthService.recordStartupSummarization`
> 
> ### Required Actions
> 
> #### 1. Timing race on async startup summarization (low severity — robustness, not correctness)
> 
> `waitForServices` in `composeWebServer.mjs` checks port-open + chroma heartbeat — it does NOT wait for `SessionService.initAsync`'s async `summarizeSessions().then(...)` to resolve before declaring `servicesReady=true`. The test then immediately reads `startup.summarizationStatus`, which can legitimately be `'not_attempted'` (the default `null` projection at line 886 of `HealthService.mjs`) if the test happens to win the race.
> 
> In practice this should be rare on an empty test substrate (drift-detection finds zero unsummarized sessions and resolves <1s after init), but under CI load + slow embedding-server startup, this could flake.
> 
> **Recommended fix:** poll-with-timeout for the primary's `summarizationStatus !== 'not_attempted'` before asserting. Pattern:
> 
> ```javascript
> test('Primary instance assumes summarization duty', async () => {
>     // Wait for async startup summarization to settle (up to 30s)
>     let primaryHealth;
>     const deadline = Date.now() + 30000;
>     while (Date.now() < deadline) {
>         primaryHealth = await callHealthcheck('http://127.0.0.1:13001', {
>             clientName: 'primary-lifecycle-test'
>         });
>         if (primaryHealth.startup.summarizationStatus !== 'not_attempted') break;
>         await new Promise(r => setTimeout(r, 500));
>     }
>     expect(primaryHealth.startup.summarizationStatus).toBe('completed');
> });
> ```
> 
> The secondary test (`'skipped-non-primary'`) is set synchronously inside the SessionService.initAsync `else if` block (line 187) so doesn't need the same poll, but mirroring the pattern keeps the spec symmetric.
> 
> #### 2. (Optional) Cover Piece C observability
> 
> [PR #10954](https://github.com/neomjs/neo/pull/10954) (in flight) adds `startup.periodicSweepStatus` + `startup.periodicSweepDetails` for the Piece C periodic sweep. After that lands, this spec could be extended with a third test asserting `mc-primary` eventually fires the periodic sweep (`status === 'completed'` after `summarizationSweepIntervalMs` elapses). NOT blocking for this PR — file as a follow-up.
> 
> ### Evaluation Metrics
> 
> - **`[ARCH_ALIGNMENT]`**: 95 — perfectly aligns with #10813 substrate. -5 because the test reads HealthService synchronously without accounting for async initAsync settling.
> - **`[CONTENT_COMPLETENESS]`**: 95 — covers both happy paths. -5 for missing the timing-robustness layer.
> - **`[EXECUTION_QUALITY]`**: 85 — clean diff, minimal scope. -15 for the timing race that may produce flakes under CI load (Required Action 1).
> - **`[PRODUCTIVITY]`**: 95 — closes #10948 cleanly with the deployed-shape proof.
> - **`[IMPACT]`**: 90 — highest-leverage integration test for the #10813 / #9999 critical path. Validates the Piece A primary-flag gate at deployment scale.
> - **`[COMPLEXITY]`**: 30 — Low: docker-compose volume + 2 short test methods + readiness-check extension.
> - **`[EFFORT_PROFILE]`**: Quick Win — high-leverage substrate proof for the v13 critical path; can ship as-is once the timing-poll lands.
> 
> ### Test-Execution & Location Audit
> 
> - ✅ Canonical location: `test/playwright/integration/` is the correct root per the integration suite convention
> - ⚠️ Empirical test execution: PR body notes L1 (local) skipped due to no Docker locally; awaiting L4 CI run on the integration matrix row. Will rely on CI signal.
> 
> ### Cross-Skill Integration
> 
> - ✅ Doesn't conflict with existing #10817/#10818 substrate (this is a deployment-shape consumer, not a producer)
> - ✅ Aligns with #10945 epic structure (your #10948 sub-issue claim and lane execution)
> 
> ### Closing
> 
> Architecture is right, scope is tight, the v13-critical-path-proof value is high. Address Required Action 1 and this lands clean. Required Action 2 is genuinely optional follow-up work, not a blocker for this PR.

> ❋ ## Cycle 2 — [APPROVED]
> 
> `474a00569` cleanly addresses Required Action 1. The `expect.poll` pattern with 15s timeout is idiomatic Playwright and structurally cleaner than my hand-rolled while-loop snippet — it natively integrates with the assertion framework's retry semantics + provides built-in failure messages. Symmetric application to both primary and secondary keeps the spec shape consistent (and protects against future fixture-readiness drift).

Architectural Hallucination: The entire concept of primary/secondary multi-instance deployments sharing SQLite is obsolete. The factory pattern implemented via RequestContextService means the multi-user remote deployment is ONE instance handling multiple agents concurrently. I am dropping this PR, reverting the compose changes, and will drop the underlying ticket #10948.
