Provenance

Origin: EternalJK

Ultimate-origin introduction: 37a07abc8b26 in EternalJK (content authored 2013-04-30, integrated 2014-03-30)
Upstream registration evidence: codemp/client/cl_console.cpp:540
Attribution method: shared-earliest-commit-lineage-order
Attribution confidence: medium
Notes: eternaljk retains origin because content authorship and PR submission predate the project that merged the work first. The earliest authored/submitted introduction is shared by eternaljk, taystjk, japro, vulkan; fork-lineage order selects eternaljk.

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.

Date	Change source	Commit / subject	Evidence	Confidence
`2014-03-30`	OpenJK	`4e834782a30a` [SP] Console no longer uses frac in determining opacity. Renamed the cvar for this fix. SetColor call now sets RGB to 1.0f instead of 0.0f, as it should.

`2015-11-24`	EternalJK	`c8f6ea17a324` Remove SP code	Changed registration, default, flags, module, renderer scope, handler, or gating. `code/client/cl_console.cpp`	`medium`
