# CHECK-q155 -- the 2026-11-02 workqueue census graded the queue it described,
# and now does so from bytes it can name.
#
# THE DEFECT THIS GRADES (measured at 0ec1c64, before this tick's edits)
#   `wizard-work/ledger/2026-11-02-workqueue-census/CHECK` was a Python program
#   with a `python3` shebang, so `bash CHECK` -- the invocation every caller in
#   this tree uses -- read rc 2 on shell syntax errors before grading a cell.
#   Behind that, it re-derived its rows from the LIVE WORK-QUEUE.md: the queue
#   is append-only, so the next item to land reddened a census whose 88 rows
#   were never wrong. Measured in a scratch copy: baseline rc 0; one appended
#   `## Q199 -- ...` heading -> rc 1, three legs failing (row count, headings,
#   manifest.rows). And the manifest carried no revision at all, so nothing said
#   which queue state the rows described; the README's stated source sha256
#   (`cea6cd3c...`) did not match the file it named (`ceb6cd3c...`).
#
# WHAT THIS GRADES
#   1. gate    bash CHECK -> rc 0 on the committed artifact, and it names its pin
#   2. probes  probe_census.sh -> 13/13 cells read the code they must: mutated
#              Title/Q cells rc 1, corrupted digest rc 1, pin revision that does
#              not hold the blob rc 1, absent blob/TSV/grader rc 2, a queue
#              append absorbed as ADVISORY at rc 0, a dirty extractor refused at
#              rc 1, and --allow-dirty's unpinned manifest left ungradable at rc 2
#   3. lint    the documented invocation is a SOUND CHECK line (tools/check_lint)
#
#   rc 0 every leg holds   rc 1 a leg failed   rc 2 could not grade
