Track T by default: the FAILING STEP named no owner. Line 70 of 76 is grep -q 'warning: __thread is x86-64 only' /tmp/ctls_rv.log || { echo "FAIL ctls: riscv32 degraded SILENTLY -- no warnin. The job's own src (test/c_thread_local_is_per_thread.c, 5 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.

• Failing step: line 70 of 76 of the job's recipe; it names no source file of its own — so it is the JOB's sources, one line up, that are unproven here, not this step's.

2026-09-24 (frankS): re-laned to A, fixed

The edfcc2c0d4 author. The failing step was an OLD assertion that the refusal still happens; fixed against what the tree does now and checked by hand against the edfcc2c0d4 binary (ffae15b05785): both rows PASS.

• 2026-09-24 — resolved; this names the commit that carried the resolve, which is not always the one that carried the change — commit a34ce5e04.
