Track T by default: the FAILING STEP named no owner. Line 2 of 13 is out=$(timeout 60 /tmp/test_ts_hl_diag26 2>&1); rc=$?; \ tools/expect_same.sh test_ts_hl_diag26_exit "$rc" "212" && \ too. The job's own src (test/test_threadsafe_heap_lock_deadlock_diag.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_threadsafe_heap_lock_deadlock_diag, and that is not what broke. The slug is derived from the job's src: selector so that it stays stable across a renumbering — it is the dedupe key and the close key — but src: says what the job is ABOUT. The failing step names expect_same. Read the Failing step: bullet, not the file name in the title, before you reproduce anything: the row the slug names may be passing.

origin/master has advanced 3 commit(s) since this sha. Re-verify at current HEAD before acting — the callback is tagged to the sha that was tested, which may no longer be the state of the tree.
