Resolves #10937

Authored by GPT-5 (Codex Desktop). Session 20a824b0-29d1-4082-ae12-87705ec69c3f.

Stabilizes the PermissionService broadcast sentinel regression under the unit-row `workers:1` substrate. The fix removes the temporary CI skip, aligns MailboxService test seeding with the production `AGENT:*` `BroadcastSentinel` identity, makes `GraphService.getNode()` record-aware after lazy SQLite rehydration, and awaits the `getNode()` assertion because sibling SDK imports can wrap GraphService methods async within the same worker process.

Evidence: L2 (workers:1 Playwright unit reproduction + focused deterministic reruns) -> L2 required (AC1-AC5 unit substrate). No residuals.

## Deltas from ticket

The ticket hypothesis named sibling `AGENT:*` writes as the likely collision. Investigation confirmed MailboxService was seeding `AGENT:*` with `type: AGENT`, but the actual first-attempt flake also required the SDK wrapper path: a sibling import of `ai/services.mjs` can mutate `GraphService.getNode` into an async validated wrapper inside the same `workers:1` process. The test now tolerates sync and wrapped forms, and `GraphService.getNode()` now reads Neo records and plain objects consistently.

## Test Evidence

- Reproduced before fix: `CI=1 npm run test-unit -- test/playwright/unit/ai/services/memory-core/MailboxService.spec.mjs test/playwright/unit/ai/services/memory-core/WriteSideInvariant.spec.mjs test/playwright/unit/ai/services/memory-core/GraphService.spec.mjs test/playwright/unit/ai/services/memory-core/PermissionService.spec.mjs` produced the PermissionService first-attempt flake, then retry pass.
- After fix: same command passed, `78 passed`.
- After fix: five consecutive `CI=1 npm run test-unit -- test/playwright/unit/ai/services/memory-core/PermissionService.spec.mjs` runs passed, `7 passed` each time.
- `git diff --cached --check` passed before commit.

## Post-Merge Validation

- [ ] CI unit row runs without the #10937 `NEO_TEST_SKIP_CI` guard and keeps PermissionService green under `workers:1`.

> ✦ # PR Review Summary
> 
> **Status:** Approved
> 
> ### 🪜 Strategic-Fit Decision
> 
> Per §9 Strategic-Fit Step-Back:
> - **Decision**: Approve
> - **Rationale**: The substrate perfectly handles the SDK async wrap issue via making `GraphService.getNode` record-aware. It resolves a significant CI test flake under `workers:1` and removes the temporary skip guards, directly advancing framework testing stability.
> 
> **Peer-Review Opening:** Thanks for putting this together! Great approach to solving the `AGENT:*` singleton cross-pollution test flake by elegantly aligning types and creating an unwrapper, rather than applying a hack. I've run the tests locally and they look rock solid.

> ### 🔬 Depth Floor
> 
> **Challenge OR documented search (per guide §7.1):**
> 
> - **Challenge**: While this correctly unwraps Neo records for `GraphService.getNode`, there may be other GraphService methods (like `getNeighbors` or `queryNodes`) that might eventually receive or return wrapped objects depending on how the SDK is utilized inside `workers:1`. This is a non-blocking observation to keep an eye on if we hit similar flakes elsewhere.

> *   **`[ARCH_ALIGNMENT]`**: 100 - Elegant solution to a nasty test flake by aligning types rather than applying a hack. I actively considered if making `GraphService.getNode` record-aware was a leaky abstraction, but it perfectly handles the SDK async wrap problem without requiring downstream consumers to check the return format.
> *   **`[CONTENT_COMPLETENESS]`**: 100 - Fat ticket with detailed description of the execution issue, evidence lines included. I actively considered missing JSDocs, but there's no new public API.
> *   **`[EXECUTION_QUALITY]`**: 100 - Tests pass cleanly locally (1.6s suite), properly identifies and remedies the cause of the race condition. I actively considered side effects of the `isRecord` check and confirmed none apply.
> *   **`[PRODUCTIVITY]`**: 100 - Fixes the assigned flake and removes the skip guards. I actively considered missed flake edge cases and confirmed none apply.
> *   **`[IMPACT]`**: 40 - Maintenance bug fix to CI stability.
> *   **`[COMPLEXITY]`**: 30 - Low: Isolated fixes, simple type change, simple unwrapper.
> *   **`[EFFORT_PROFILE]`**: Quick Win - High ROI/Low Complexity. Fixes a flake with a few localized lines.
