# against a RESEARCH doc. Checks 4 and 5 read it against the skill's own
# sources.md and honoured neither half: a truthiness test collapsed None into
# [], so an unreadable Contributing files block disabled both checks and the
# script still exited 0 with no output — the failure mode
# parse_contributing_files' docstring names in as many words. The assertions
# below are therefore about the INFO appearing; a silent exit 0 is exactly the
