Ride + corridor showed no corridor: with a room present the viz plays on its screens (radio/window/wall), so a dark model viz on the Ride's dash radio is invisible, and the shared rig was filming it through the room camera grammar meant for another world (directCamera rooms now keep the subject grammar + viz framing). Battery pins switched to combos that visibly read (Chamber + Kaleido, Stage + Assembly); scenario text states the visibility rule so a dead pin can't hide again.
Actors and objects change only at camera cuts. int/bool/discrete
params skip drift, lookahead and reactivity; discrete slowAxis steps
on the section-held journey. Venues fade instead of toggling on
interpolated popMul; roadside density is arrangement-only.
DESIGN.md collects the project's design decisions; AGENTS.md points
agents at it and the build-visualizer loop.
