"""MultiProjectCITelemetrySource fans out the hardened per-project CI lookup.

One red project yields a breaching sample; a green one a non-breaching sample; a
None signal or a per-project error yields NO sample (unknown, never "green") and
never aborts the sweep. Each project's ci_watch_workflow (or the configured
default) is passed through to the reused lookup.
