Track guessed as N from the test source. The failing step (line 2 of 3) named no source of its own, but this job has only ONE source — so first-source and only-source are the same file here and there is no other lane in frame. 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 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 2 of 3 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.

Range

bad 759c3fe03246, and this is the job's first-ever run — there is no earlier passing sha, so no interval contains the cause and every commit a range could name is equally innocent. No idle bisect will happen; a red here is a finding about the job, not a regression from the commits around it.
