before it switches the service. Precompile uses two low-priority processes by

1–16 process count for the host. A failed worker, compile, serialization, or

result report aborts the switch and leaves the current service running. The
managed invocation is bounded to 900 seconds by default; set
`UCE_PRECOMPILE_TIMEOUT` on `manage-uce-service.sh restart` to select another
GNU `timeout` duration. Timeout exit 124 also aborts before the service switch.
A trusted direct `--precompile` process may set `UCE_PRECOMPILE_FILES_IN` and
`UCE_PRECOMPILE_BIN_DIRECTORY` to isolate that invocation's source scan and
artifact registry. Both overrides apply only to precompile mode; normal server
workers continue to use `/etc/uce/settings.cfg`. The parallel precompile
regression uses private roots so a running proactive compiler cannot consume
or publish its controlled race fixtures.
Equivalent manual systemd service for a source checkout (`<UCE_REPO>` = checkout root):
