FW-490 Idea Register
The register contains exactly 490 stable collection items from FW-001 through FW-490. An item remains a collection item: idea ≠ decision ≠ entity ≠ requirement ≠ implementation.
FW-153 regression: Catalog/ID presence or a code reference is not presented as implementation_present without matching code scope and suitable evidence.
