Attribution confidence: high
Notes: Identifier is present in OpenJK’s initial Raven source-import snapshot. Dated commit evidence identifies later registration changes relative to the origin snapshot.

Later changes

These commits occur after the ultimate-origin introduction on TaystJK’s inherited first-parent lineage. Registration evidence is exact; behavior evidence requires a changed bound cvar reference or a changed registered command-handler hunk.
