Track T by default: the FAILING STEP named no owner. Line 2 of 2 is tools/expect_same.sh cmath_lround "$(/tmp/cmath_lround)" "$(printf '0.5 lround=1 llround=1 lrint=0\n1.5 lround=2 llround. The job's own src (test/cmath_lround.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.

This commit CANNOT be the cause. The job builds only with $(PXX_STABLE), and this commit moved no stable_linux_amd64/** — so the bytes that compiled it are unchanged. Look at flakiness or box load, not at the named sha; the bisect is unsound here and has been skipped.

origin/master has advanced 6 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 2749b12c2e93 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 2749b12c2e93, last good 08b0f50df2ac, 1 observable commit(s) in range (it builds with $(PXX_STABLE), so compiler/ commits cannot have caused it and are dropped; pin moves, lib/ and test/ are kept) — the watcher narrows this by idle bisect.
