Track T by default: the FAILING STEP named no owner. Line 2 of 14 is
tools/expect_same.sh test_cast_deref_varparam26 "$(/tmp/test_cast_deref_varparam26)" "$(printf 'abc 3')". The job's ownsrc(test/test_cast_deref_varparam.pas, 2 file(s)) is NOT used here on purpose: it is what the job compiles, not what broke, and guessing a lane from it is what sent three reds in one job to the wrong lane. This is a FALLBACK, not a finding — nothing says the defect is Track T's. Re-lane it before working it.
The SLUG names
test_cast_deref_varparam, and that is not what broke. The slug is derived from the job'ssrc:selector so that it stays stable across a renumbering — it is the dedupe key and the close key — butsrc:says what the job is ABOUT. The failing step namesexpect_same. Read theFailing step:bullet, not the file name in the title, before you reproduce anything: the row the slug names may be passing.

Range
The named sha
4fbed6c4157eCANNOT be the cause — it touches no buildable file (docs / tickets / tstate only). It is the sha that was TESTED, i.e. the upper bound of an untested range; the cause is somewhere below it.
bad 4fbed6c4157e, last good 7f86a12a6628, 4 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.
