Track A from the job NAME
test-emit-obj, not from its source. This job names a MECHANISM rather than a subject — the source it was fed (test/c_threadsafe_object_offset_zero.c) is what the mechanism was run ON, not what is being tested, so a lane guessed from it would be wrong by construction. The ranker reads frontmatter, so this line decides who works it; re-lane it if this job has changed what it covers.
The SLUG names
c_threadsafe_object_offset_zero, 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 namesemit_obj_target_set_check. Read theFailing 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 12 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
aef4ee1310f9CANNOT 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 aef4ee1310f9, last good f88e0ea1f464, 2 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.

Log
- 2026-09-25 — the borg watcher saw
test-emit-obj#src:test/c_threadsafe_object_offset_zero.c@2GREEN at dcb660109dad (tier full) and did NOT close this: the job's class iscorpus, which testmgr treats as runtime-nondeterministic (RUN_RETRY_CLASSES) — a single pass does not refute a red there. The green is recorded because it is evidence and because a ticket that stops moving with no reason reads as forgotten; closing this one is a human's call.
