 - The dead Unity `NameFile` projection class has been deleted. Runtime name
   generation reads `AetheriaRuntimeNameFile` records from the typed catalog
   facade; legacy `GameData/NameFile/*.msgpack` remains migration input only.
+- Pending Unity runtime commit envelopes now name their source catalog IDs as
+  `CorporationLegacyId`, `ItemDefinitionLegacyId`, and
+  `HullItemDefinitionLegacyId`; the applier has always projected those fields
+  into typed corporation and item-definition record keys.
 - Entity restore and loadout manufacturer-distance weighting no longer read
   legacy `Faction` entries through `ItemManager`; they use `Galaxy.ResolveFaction`
   over the typed corporation projection.
