Track T by default: the FAILING STEP named no owner. Line 2 of 2 is
tools/expect_same.sh c_szfldptrarr26 "$(/tmp/c_szfldptrarr26)" "FIELD PTRARR OK 16 32 7 24". The job's ownsrc(test/c_sizeof_ptr_to_array_field.c, 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
c_sizeof_ptr_to_array_field, 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
e4203b5aeed9CANNOT 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 e4203b5aeed9, last good 6bfc726d5677, 1 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.
