The census CHECK asserted that the committed TSV re-derives from
WORK-QUEUE.md as it stands on disk. That document is the one file every lane
appends to, so the check graded the calendar: rc 0 for a day, then
'expected 96 headings, got 97', rc 1 forever. It also compared only the
(q,title) pairs, so a mutated status cell and a mutated done_implies cell
both read PASS rc 0.
- verify_workqueue_census.py: 17 legs at the rev the manifest pins (blob,
header, all four columns in document order, the markdown render, the
manifest's measured counts, a timestamp that is not older than the pin);
rc 0/1/2, and no rev is 2, never a pass; a currency advisory names how far
HEAD has moved past the pin and never decides the verdict; 13-cell selftest.
- extract_workqueue_census.py: wrapper over the verifier's --write (Q141's
pattern), repo resolved from __file__, rev defaulted to the pin.
- manifest.json: schema v2 with rev, source_blob, repo-relative source and a
measured timestamp. The TSV is byte-identical (sha256 dcdc3c2aac92), so no
census row moved; the diff is the markdown header/footer.
- CHECK-q147: a root entry point grading the repair in four legs.
