- **Log timeliness**: the base process line-buffers stdout before forking
workers, the proactive compiler, and the WebSocket broker. This keeps each
newline-terminated diagnostic attached to its actual journal time instead of
releasing an old block-buffered failure during unrelated later traffic.
releasing an old block-buffered failure during unrelated later traffic. The
private CLI timing gate labels its deliberate invalid-source request as
`UCE expected compile error`; public and unmarked CLI compilation failures
retain the ordinary `UCE compile error` operator signal.
- **WebSocket end-to-end**: a headless client performs a raw WS handshake to
`:HTTP_PORT` with path `/site/tests/websockets.ws.uce` (self-resolving
