Admin only. Runs in background. Body accepts three shapes (all optional — empty body / `null` syncs every registered table): - ``["kbc_job", "orders"]`` — bare JSON array of table ids - ``{"tables": ["kbc_job", "orders"]}`` — object with a ``tables`` key (matches the wire shape of the response, more discoverable for clients building requests by hand) - ``null`` / no body — sync everything Both array forms have shipped at different times; accepting both keeps older clients (PR-build CLIs, helper scripts) working while surfacing the shape that mirrors the response payload. Anything else returns HTTP 422 with a structured detail. Returns 409 if a previously-triggered sync is still running. Two concurrent extractor subprocesses fight for the same `extract.duckdb` file lock — that contention starves uvicorn, makes `/api/health` time out, flips the container to `unhealthy`, and (behind a `reverse_proxy` upstream like the bundled Caddy overlay) bricks external traffic until contention drains. Fast-fail here keeps that from happening.
