Track T by default: the FAILING STEP named no owner. Line 2 of 2 is tools/expect_same.sh crtl_tiny_regex_match26 "$(/tmp/crtl_tiny_regex_match26)" "tiny-regex: all cases pass". The job's own src (test/crtl_tiny_regex_match.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.

origin/master has advanced 1 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.

Log

• 2026-09-01 — the seven watcher saw test-core#src:test/crtl_tiny_regex_match.c GREEN at 747d3479f74e (tier native) and did NOT close this: the job's class is corpus, 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.

VERIFIED FIXED 2026-09-01 (frankC) — no longer reproduces at HEAD

Swept as part of "which of the 12 open auto-filed regressions still reproduce?". Re-ran this ticket's OWN job recipe at 2d9878ac8, compiler 6afb21f66d10 (built from the pin, self-host fixedpoint converged):

PXX_ALLOW_FULL_SUITE=1 tools/testmgr.py --tier native --job 'test-core#src:test/crtl_tiny_regex_match.c'

GREEN, twice. Run a second time deliberately: a single green run on a regression that may be intermittent proves nothing, and this test's population includes at least one known race. Two independent runs, both green.

Cause NOT bisected, and this ticket does not claim one. It no longer reproduces; which commit fixed it is unestablished. Recorded that way on purpose — an invented cause is worse than an absent one, and the bisect range in this ticket dates the window it was FILED in, not the window it was fixed in.

• 2026-09-01 — resolved; this names the commit that carried the resolve, which is not always the one that carried the change — commit bee5a0d19.
