Against the vendor-page wording (the official document was not retrievable), ucsrename at 9fa4543 is stricter than the 'CatID-only' reading: it requires FXName, CreatorID and SourceID, supports only UserData as an optional block, forbids underscores in every field, and converts spaces to hyphens. ucs-tools at 2e307eb follows the 'CatID-only' reading in parse and validate (and reports FULL versus MINIMAL), supports UserCategory and VendorCategory, but its compose command requires FX, creator and source arguments. The two also bundle different list versions: ucsrename 8.2 (WOODHandl), ucs-tools 8.2.1 (WOODHndl).

Curator qualifications: Excerpted evidence located; tools disagree on required fields (ucsrename required vs ucs-tools optional) - kept.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
