feat(B.13-B.17+B.16): Error-Handling-Infra, Observability, Graceful Shutdown, Cost-Cap, API Versioning
B.13 Error-Handling-Infrastruktur:
- ErrorCategory Enum (TRANSIENT/PERMANENT/PARTIAL), ApiError erweitert
- Einheitliches Error-Response-Format: {code, detail, field, trace_id, retryable, category}
- 3 FastAPI Exception-Handler (ApiError, HTTPException, unhandled)
- classify_exception() Helper, 6 neue Error-Codes
- 28 Tests in test_error_handling.py
B.14 Observability & trace_id-Korrelation:
- trace_id pro Request (UUID4 short) in structlog contextvars
- X-Trace-Id Response-Header
- Sensitive Fields structlog processor
- llm_complete()/llm_embed() akzeptieren trace_id kwarg
- 12 Tests in test_observability.py
B.15 Graceful Shutdown & Connection Draining:
- _shutdown_event + _inflight_requests Tracking in main.py
- drain_all_connections() in ws_helpers.py
- Worker on_shutdown pausiert WorkflowInstances (status=paused)
- 8 Tests in test_graceful_shutdown.py
B.16 API Versioning Strategie:
- Plugin-Dev-Guide Kapitel 30: URL-basiertes Versioning, Breaking Change Prozess
B.17 Cost Overrun Protection:
- llm_monthly_budget_usd + llm_hard_cutoff Settings
- _check_tenant_budget() vor jedem LLM-Call
- _track_tenant_cost() in Redis (INCRBYFLOAT)
- _check_cost_alerts() bei 50%/80%/100% -> post_system_message()

B-WS: app/core/ws_helpers.py (NEU) — gemeinsame WebSocket Helpers
- authenticate_ws: Session-Auth für WebSocket (Cookie/Token → User/Tenant)
- check_ws_origin: Origin-Check (delegiert auf verify_ws_origin)
- check_ws_tenant: User-Tenant-Membership-Check
- cleanup_ws_connection: Connection aus Registry entfernen + WS schließen
- start_heartbeat: Background Ping-Task
- send_ws_error: strukturierte Error-Message an Client
- handle_ws_message: Message-Dispatch mit Error-Handling
B-WS: app/core/ws_pubsub.py (NEU) — Redis Pub/Sub für Multi-Worker-Fanout
- publish_to_channel / subscribe_to_channel
- get_tenant_channel / broadcast_to_tenants
B-WS: WebSocketManager + AIUIControlWSManager angepasst
- connect() nutzt authenticate_ws + check_ws_origin + check_ws_tenant
- disconnect() nutzt cleanup_ws_connection + cancelt Heartbeat/PubSub
- broadcast() unterstützt Redis Pub/Sub Fanout
B-ERR-WS: WS Error-Handling in ws_helpers integriert
- send_ws_error für strukturierte Errors
- handle_ws_message fängt Handler-Exceptions
B-WS-TEST: 24 Tests in test_ws_helpers.py — alle grün
- Auth, Origin, Error, Dispatch, Cleanup, Heartbeat, Pub/Sub Roundtrip
