Root cause: ensure_structured_column() executed a synchronous blocking engine.connect().execute(SELECT information_schema.columns ...) inside the async request path (_build_chat_history / _maybe_compress_history), freezing the uvicorn event loop and hanging all endpoints (~200s, recovered only by docker restart). Fix: - chat_context.py: remove per-request ensure_structured_column() calls; run once idempotently at app startup (main.py lifespan). Use CURRENT_DATABASE() for PostgreSQL compatibility. - main.py: add startup-only ensure_structured_column() hook (try/except). - llm_client.py: trust_env=False + bounded httpx.Timeout/wait_for so broken endpoints fail fast instead of hanging the event loop. - chat_service.py: run media generation in a background daemon thread with its own event loop (_launch_media_task_bg) so SSE end does not cancel image/video tasks (#811); remove TEMP faulthandler diagnostic. Safe-align: persist accumulated live container changes (admin/*, knowledge, market, models, config, observability, mcp_client, platform_knowledge, im_bot_platform, chat_media, capability_registry, requirements) and add workflow_templates. Verified: live failover test (model-006 -> conn-refused) returns in ~1.9s with concurrent login 0.83s/200; event-loop responsiveness restored (sub-second).
