"""Runs inside the archipelago Docker image. Reports which game (if any)
a single mounted .apworld registers itself as under Archipelago's own
World registry - the import/registration step only, no seed generation.

Used to verify a freshly downloaded .apworld's actual content matches
the sheet row that fetched it, rather than trusting release/asset
name-matching alone (see AssetMatcher): the filename
and release title are just text an author chose, but AutoWorldRegister
is filled from the World class's own "game" attribute, which is what
Archipelago itself will treat this file as - the authoritative source.
