Devin	bf12f94250	Redis-backed Event Bus broker (feature-flagged via REDIS_URL) Some checks failed CI / Frontend Lint (pull_request) Failing after 7s Details CI / Frontend Type Check (pull_request) Failing after 6s Details CI / Frontend Build (pull_request) Failing after 7s Details CI / Frontend E2E Tests (pull_request) Failing after 8s Details CI / Orchestrator Build (pull_request) Failing after 6s Details CI / Contracts Compile (pull_request) Failing after 7s Details CI / Contracts Test (pull_request) Failing after 6s Details Code Quality / SonarQube Analysis (pull_request) Failing after 19s Details Code Quality / Code Quality Checks (pull_request) Failing after 4s Details Security Scan / Dependency Vulnerability Scan (pull_request) Failing after 5s Details Security Scan / OWASP ZAP Scan (pull_request) Failing after 3s Details Closes gap-analysis v2 §7.3 and §10.3. - New services/eventBusBroker.ts: per-process singleton with unique instanceId; subscribes to a Redis pub/sub channel (default ccombo:events) and re-emits inbound records on the in-process EventEmitter. Outbound envelopes carry the instanceId so the originating replica drops its own echo. - eventBus.publish() hands every persisted record to the broker after the local emit, so same-process SSE subscribers see zero change while remote-replica subscribers now receive every event. - When REDIS_URL is unset the broker is strictly inert (no connect, no publish) — single-process behaviour is preserved byte-for-byte. - 3 unit tests for feature-flag semantics; full suite 83/83 green. - Live Redis behaviour will be covered by the Testcontainers suite in PR Q.	2026-04-22 18:09:02 +00:00
