`r_fastsky`

Base Jedi Academy

Needs review. The inventory/provenance evidence is recorded, but some behavior, options, or attribution still lacks a direct user-facing source.

Controls r_fastsky in the renderer module. Consult the cited behavior reads before relying on values not listed here.

Provenance

Origin: Base Jedi Academy

Baseline evidence: 14cea1563762
Upstream registration evidence: code/renderer/tr_init.cpp:1162
Attribution method: present-in-openjk-initial-source-import
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.
