-CustomerCore API — Server-Sent Events (SSE) Stream Router (Phase 10)
-
-WHY SERVER-SENT EVENTS INSTEAD OF WEBSOCKETS?
------------------------------------------------
-Both SSE and WebSockets provide real-time server → client communication.
-The key difference:
-
-  WebSocket:
-    - Bidirectional (both client and server can send messages)
-    - More complex to implement (requires upgrade handshake, heartbeats, reconnection logic)
-    - Better for chat applications, collaborative editing, live games
-
-  Server-Sent Events (SSE):
-    - Unidirectional (server → client only)
-    - Uses a regular HTTP connection — works through proxies and firewalls that block WebSockets
-    - Browsers handle reconnection automatically (EventSource API)
-    - Built-in support in FastAPI via StreamingResponse
-    - Ideal for: progress updates, live logs, dashboard feeds
-
-CustomerCore's triage stream is read-only from the client's perspective — the client
-watches triage progress but doesn't send messages. SSE is the correct choice.
-
-HOW IT WORKS:
-  1. Client subscribes: GET /api/v1/triage/{ticket_id}/stream
-  2. Server opens a long-lived HTTP connection
-  3. As the triage progresses, the server pushes status events:
-       data: {"status": "processing", "step": "classify_agent"}\n\n
-       data: {"status": "processing", "step": "rag_agent"}\n\n
-       data: {"status": "complete", "result": {...}}\n\n
-  4. Client closes the connection when it receives status=complete or status=failed
-
-SSE EVENT FORMAT (per the W3C spec):
-  data: <json_payload>\n\n
-  The double newline signals the end of one event — the browser's EventSource parses this.
+CustomerCore API — Server-Sent Events (SSE) Stream Router (Phase 13)
+
+Wires the Supabase persistent repository layer into the streaming endpoints.
+Replaces the in-memory triage_store with TicketRepository.

-CustomerCore API — Triage Router (Phase 10)
-
-This is the core of the CustomerCore API — the routes that accept tickets,
-invoke the LangGraph 6-agent supervisor, handle HITL pausing, and return results.
-
-ASYNC BACKGROUND PROCESSING:
-------------------------------
-Ticket triage is NOT synchronous. The LangGraph supervisor makes LLM calls that
-take 2–8 seconds. We cannot block the HTTP connection for that long because:
-  - HTTP clients have timeouts (usually 30s, but we target <10s response)
-  - Blocking threads wastes server resources
-  - The caller doesn't need to wait — they can poll or subscribe to SSE
-
-Pattern used (async background task):
-  1. POST /triage → immediately return ticket_id + status=pending (200ms)
-  2. FastAPI BackgroundTasks schedules the LangGraph run asynchronously
-  3. Client polls GET /triage/{id} OR subscribes to GET /triage/{id}/stream (SSE)
-  4. When complete, GET /triage/{id} returns the full result
-
-This is the same pattern used by OpenAI's batch API, Anthropic's async API,
-and every production ML inference system that takes >1s per request.
+CustomerCore API — Triage Router (Phase 13)
+
+Wires the Supabase persistent repository layer into the triage routes.
+Replaces the in-memory triage_store with TicketRepository.
