Track T from the job NAME tools-devtest, not from its source. This job names a MECHANISM rather than a subject — the source it was fed (none) is what the mechanism was run ON, not what is being tested, so a lane guessed from it would be wrong by construction. The ranker reads frontmatter, so this line decides who works it; re-lane it if this job has changed what it covers.

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.

• Type: regression (auto-filed by Track T watcher, host seven, twatch 0c5ad13167ab). Untriaged.
• Found: 2026-09-09T06:23:41Z
• Test source: unknown (see repro commands)
• Failing step: line 1 of 1 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.

• 2026-09-09 — the seven watcher saw tools-devtest#00 GREEN at 8c0ccdd019f8 (tier full) and did NOT close this: this is a repeat stub (regression-tools-devtest-00-4, not regression-tools-devtest-00) — the job already went red, was closed, and came back, so one green is the outcome a live intermittent bug produces most of the time. 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.
