Upstream registration evidence: codemp/cgame/cg_xcvar.h:140
Attribution method: squash-feature-group-explicit-credit
Attribution confidence: medium
Notes: The earliest authored/submitted introduction is shared by eternaljk, taystjk, japro, vulkan; fork-lineage order selects eternaljk. The identifier’s single-prefix squash feature group explicitly credits japro.

Dated project introductions

Authored dates come from the exact registration’s first content commit, PR dates identify when work was proposed to each project, and integration dates come from each first-parent mainline. A project merging first does not override earlier upstream authorship or submission.

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.
