 The temporary `engineImportExceptions` list in `scripts/package-boundaries.json`
 contains exact file/package pairs with reasons. The checker reports the used
-entries and rejects duplicates, missing reasons and unused entries. Its three

 Source-only factories use dedicated `layers/<family>/source` exports where
 available, preserving the same factory implementation without loading rendering.
