Track T by default: the FAILING STEP named no owner. Line 6 of 10 is tools/expect_same.sh hostshape26/native "$(/tmp/test_nilpy_hostshape26 2>/dev/null)" "$(printf 'HOSTSHAPE-MODE wide\nHOS. The job's own src (test/test_nilpy_reflected_host_call_shapes.npy, 3 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_nilpy_reflected_host_call_shapes, 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 9 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.

Range

The named sha 1086f130add0 CANNOT 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 1086f130add0, and this is the job's first-ever run — there is no earlier passing sha, so no interval contains the cause and every commit a range could name is equally innocent. No idle bisect will happen; a red here is a finding about the job, not a regression from the commits around it.
