Track guessed as N from the FAILING STEP — line 2 of 7, /tmp/test_nilpy_openworld26 | diff -u test/test_nilpy_open_world_method_dispatch.expected -, which names test/test_nilpy_open_world_method_dispatch.expected. Not from the job's name or its src: those describe what the job is ABOUT, and this job's recipe spans 2 source file(s). The ranker reads frontmatter, so this line — not the body — decides who works it; correct it if the guess is wrong.

origin/master has advanced 4 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 67f0878f2e59 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 67f0878f2e59, last good e572bd42501e, 1 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.

CENSUS 2026-09-19 (frankS) — does not reproduce; closed by events

Run through testmgr's own job runner, using this ticket's exact Repro line — the instrument that filed it, and the one auto-pin reads. Not through make, and not through a hand-run of the fixture:

tools/testmgr.py --tier full --job <this ticket's own literal job selector>
->  testmgr: GREEN, 1/1 pass

All 17 open NilPy regressions were run that way and all 17 came back GREEN.

The census carries a positive control drawn from the same population, because seventeen greens from an instrument nobody has shown can fail are not evidence. Same runner, same tier, on the xmlreader job — which is still built by the PINNED compiler and therefore still broken — the identical form returns:

expect_same: MISMATCH [lib_mimic_xmlreader.1]
--- expected
+++ actual
@@ -1 +1 @@
-25
+24

testmgr: RED

So GREEN here means the job passed, not that the runner is blind.

This does not say the report was never real. It was real at its filing sha; the tree has moved past it. Closed as NOT REPRODUCING, so it stops occupying a ranked slot and stops being dispatched to.

Why a whole pile went stale at once, which is the part worth keeping: these are auto-filed by the Track T watcher, and the watcher DOES retire them — 19 open tickets have a twin in done/ and every one of those twins carries the line auto-closed by the borg watcher. The defect is narrower than "nothing closes them": the auto-close WRITES the closed copy into done/ and does not remove the backlog/ original. The duplicate then keeps a real prio, so it goes on sorting alongside live work and a seat gets dispatched to a subject that has been passing for weeks — and progress.sh resolve refuses it as an ambiguous slug, which is how the pattern surfaced at all.
