Architecture conformance fix per plan §12 Phase 4: - Plan specifies Matchmaker Deployment as internal service with no external exposure - Extracted tickers.go from acb-api to new cmd/acb-matchmaker/ - Tickers: bot pairing (1 min), health checking (15 min), stale job reaping (5 min) - Alerting webhooks moved from acb-api to acb-matchmaker - Created Dockerfile for acb-matchmaker container - Created K8s deployment manifest (no service needed - internal only) - Fixed syntax error in cmd/acb-api/db.go (prematurely closed schemaSQL string) This separates concerns per the plan: - acb-api: HTTP endpoints for bot registration, job coordination, bot status - acb-matchmaker: Internal tickers for matchmaking, health checks, reaping Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
