`g_tweakSaber`

jaPRO

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

Set with tweakSaber. Each bit is a separate option, so the command toggles one of them per use and leaves the rest alone. Setting a raw value by hand replaces every option at once.

Configured with /tweakSaber command.

Bits

Use tweakSaber to toggle one option at a time; see the command page for syntax. The value column is that bit on its own. The labels come from the source table.

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.

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.
