The 2:25 slow run left exactly one red: kimi-for-coding answers 404
model_not_found because the channel removed it from the account group
between 09:44 (four green probes, correct model_reported) and 15:00. L8
was reading that as "the capability table drifted", which is a statement
about the model the channel no longer serves.
The 404/model_not_found rule already used by T10 now lives in one helper
and is applied on the L1-L9 side too, via the same unreachable fallback:
that one rejection skips and records an uncovered row, every other
RequestRejectedError still bubbles, since those are the real failures
this suite exists to catch.
