The first whole-gate run went red on a defect in this tick's own artifact:
docs/queue-index.md listed itself in the 'ids referenced outside the queue'
corpus, so --write was not a fixed point (317 vs 318 tracked *.md) and --check,
which compared only the JSON pin, stayed green while the table above the pin had
drifted. Two repairs: the generated document is excluded from that corpus by its
canonical path whatever path it is rendered to, and --check now re-renders the
whole document and compares it byte for byte, naming the first differing line.
check.sh 20/20; falsify 5/5.
