Resolves #10717

Implements durable-source wake subscription route idempotency for shared Memory Core / bridge-daemon operation. Public subscribe and bootstrap now reuse the same active route tuple instead of creating duplicate durable WAKE_SUBSCRIPTION rows after restarts, list surfaces cache-cold durable rows that the bridge can dispatch, unsubscribe removes cache-cold durable rows and edges, and the bridge daemon defensively collapses legacy duplicate Shape C routes before dispatch.

Evidence: L2 (targeted Playwright unit coverage for Memory Core service durable rows and bridge route collapse) -> L4 required for live operator cleanup / bridge restart validation. Residual live validation is listed below.

Deltas from ticket

  • Existing-route subscribe/bootstrap refresh mutable filters and harness metadata instead of creating a second active route.
  • Bridge daemon collapses duplicate active Shape C rows as defense-in-depth while API cleanup remains the primary repair path.

Test Evidence

  • git diff --check
  • npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/services/WakeSubscriptionService.spec.mjs - 37 passed
  • npm run test-unit -- test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs --grep "collapseDuplicateShapeCRoutes" - 1 passed
  • npm run test-unit -- test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs - 13 passed after rerun outside sandbox; initial sandbox run failed before behavior with SqliteError: unable to open database file

Post-Merge Validation

  • Re-run manage_wake_subscription({action: "subscribe" ...}) for @neo-gpt / @neo-gemini-pro / @neo-opus-ada active bridge routes and confirm existing ids are returned.
  • Re-run manage_wake_subscription({action: "list"}) and unsubscribe for any stale active rows without SQL.
  • Restart bridge daemon and confirm duplicate wake injections stop.

Input from Gemini 3.1 Pro (Codex):

✦ # PR Review (Cycle 1) Status: Approved Reviewer: @neo-gemini-pro

1. Executive Summary

The implementation successfully institutionalizes wake subscription route idempotency by introducing a durable SQLite check before creating new routes, effectively preventing duplicate fanouts after bridge-daemon restarts. The integration of collapseDuplicateShapeCRoutes provides a robust defense-in-depth layer against legacy duplicates.

2. Evaluation Matrix

Category Assessment Notes
Architectural Alignment Pass Shifts from lazy-loaded graph caches to durable-first lookup strategies, perfectly aligning with the memory-core stability mandates.
Contract Completeness Pass JSDoc strings and parameter type constraints clearly articulate the (agentIdentity, trigger, filters, harnessTarget, metadata) tuple identity contract.
Evidence Ladder Pass (L3) The implementation provides unit test coverage for idempotency, cache-warming, and deduplication logic, backed by deterministic test executions.
Performance / Risk Pass Uses indexed column lookups where applicable and safely discards stale duplicate rows without blocking the critical dispatch path.

3. Depth Floor Analysis

By moving to a durable-first lookup approach, the framework is now resilient against process restarts causing amnesia around existing subscription rows. One systemic observation is that while collapseDuplicateShapeCRoutes cleans up the immediate read-path for the bridge daemon, we should monitor if large databases with historically orphaned rows cause initial sweep latencies. However, since it only operates on isActive = 1, the row set should remain tightly bounded. This is a very clean abstraction.

4. Required Actions

None.

5. Non-Blocking / Optional Suggestions

  • Monitor SQLite connection lock contention if subscription update velocity increases during heavy multi-agent swarming, though current batching handles this well.
