Functions

router

Build the HTTP router over db. Read endpoints take the read lock; /ingest takes the write lock. Guards are dropped before any .await. GET /watch upgrades to a WebSocket fed by the post-commit sink.

router_with_auth

router with an optional bearer/?token= requirement on every route except unauthenticated GET /health.

router_with_ui

Same as router_with_auth, then ServeDir as the fallback so API routes win.

run_mcp_stdio

Run the MCP loop until reader hits EOF.

serve

Bind addr (port 0 is ephemeral) and serve.

serve_with_ui

serve plus a UI dist directory mounted behind the API routes.
