A job piped into tail loses its exit status, because the command runs under
bash -c and the sentinel then reports the pipeline's zero rather than the
job's. That is the same false-green the CRLF fix closed, arriving by a
different road, and it cost a Soul run today.
The second is smaller and just as costly to rediscover: CultLib has no
Cargo.toml at its root, so a rust job must cd into the package first or cargo
fails in a way that looks like a broken image.
