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.
Headcount split (1-3 actors by population, rest junk): actors take the
first indices so popMul gating never hides the cast while thinning junk.
Each figure is the track's monolith (shared part geometries, own palette
material, distinct entries per figure, feet planted via bbox) and walks
a closed analytic loop - stand at furniture A facing it, meet at the
centre facing its partner (a lone figure watches the window instead),
stand at furniture B facing it - on a slow seeded unsynced period.
Smootherstep legs rest at both ends, so figures pause, look, then move;
facing blends toward the next leg's target for smooth turns. Positions
first for all figures, then yaws off same-frame positions; nothing
integrates, so seeks match playback. Figures breathe brighter than junk
to read against their own room in monochrome palettes.
Verified: 24/24 tests, scene lint clean, re-render bit-identical,
chamber strips centre 0.09/0.12 (pre-existing flat), drone 0.26->0.57,
elegy 0.61->0.59, agit unchanged.
Tables, chairs, cupboards, shelves with seeded book rows, potted plants
and box stacks built from primitives, dealt from a shuffled deck per
(seed, arrangement) so the first slots always land distinct types. Same
spiral + repulsion placement with per-item footprint radii; front clamp
pulled to z<=-1.5 for furniture scale so close cameras never wear a
table as a lens bar. Static (junk doesn't bob) with the existing
story-driven emissive breathe; re-hang on arrangement jumps moves
everything under the camera cut. popKey drops the actor dependence.
Verified: 24/24 tests, scene lint clean, same-frame re-render
bit-identical, rooms read as furnished across centre/drone/elegy.
Chamber-forced strips: elegy direction 0.26->0.61; centre stays
pre-existing-flat (0.11->0.09, dark song, same early arrangement);
drone agit unchanged (viz-driven).
