The home page and the stats export counted every file carrying a provenance record, the provenance page and the README only the system files. The site published 553 and 566 for the same quantity, one click apart, and the export paired the wider count with composition.systems as its denominator. common.count_catalog_matched is now the single source, scoped to the systems bucket. The FAQ had drifted from the profiles it describes: MAME pinned at 0.287 against 0.289 in mame.yml, Adler-32 attributed to Dolphin's IPL rather than the DSP ROMs that carry known_hash_adler32, and the per-emulator verbose report named as the only content check on an existence platform, which skips the DISCREPANCY line the platform report raises itself. Tests read both sides: no generator may count matches inline, and each FAQ claim is checked against the profile or the script that owns it.
