- a player build ships beside the dev one — dev chords and probe surfaces go dark, and a gate enforces what a player can still reach, by medium not by module - the binary carries its own shaders and its shipped UI, finds the WoW folder by itself, and keeps its local state in one benilla-config folder - the glue screens get a capture shutter, and the engine stops depending on the protocol crate Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
