Track A from the job NAME test-debug-g, not from its source. This job names a MECHANISM rather than a subject — the source it was fed (tools/compiler_srchash.sh) 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 3 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 5d083bd91f9a 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 5d083bd91f9a, last good 68c168230560, 3 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.

Log tail

compiler/.pascal26.fixedpoint was written for DIFFERENT SOURCES than the tree has.
  stamp sources: <none — written before the stamp carried a source hash>
  tree sources:  e1a707c6b8f26d56792be74f7134217d0f88a3793afef9fbecf17cc77a4dad5a
A stamp NEWER than sources it does not describe is how this step
printed 'verified' three times in one day without building anything.
Recover with:  rm -f compiler/.pascal26.fixedpoint && make compiler/pascal26

Stub ticket: signal only. Track T agent (face 2) enriches or a dev track takes it from the repro line.

Log

• 2026-09-03 — auto-closed by the seven watcher: test-debug-g#src:tools/compiler_srchash.sh passes at 71a66c7d1437 (tier native); it was red at 5d083bd91f9a. Reopening is by a fresh NEW-RED stub, since a second red is a second finding with its own range.
