ActorGenerator is the cast with bodies: generateActor{mpl} takes
{summary,rng,archetype,personality,identity} and returns a serialisable
ActorSpec — same audio-tilts-centre / seed-picks-within rule as
Personality/Identity, forked rng so adding an actor never shifts later
decisions. Five archetypes (monolith/swarm/walker/vehicle/structure),
per-track actor set on look.actors, HUD helper included. Stage C will
grow as a library on this without infra changes.
Mesh twin of Identity.form: actors/meshes.js builds BufferGeometry from
the same assembly (cast SDF → Shape → ExtrudeGeometry, box/capsule/
torus/sphere primitives, symmetry folding radial/mirror/stack). Shared
with the shader impostor path — one character, two projectors.
Renderer depth targets: createDepthTarget / createTarget{depthTexture}
for WebGL DepthTexture plumbing.
Compositor shared rig: one PerspectiveCamera + DepthTexture so a ground
mesh can occlude a subject mesh from another layer. 4/scale dolly,
Personality.camera drift/sway/spin, framing shift — matches particles.js
and shader epilogue behaviour. ModelLayer (kind:model) with
build/update(actorSpec) and sharedCamera injection; createLayer dispatches
on model. Shader contract gains MODEL_PREAMBLE.
LookGenerator now derives actors before scenes; ArcDriver._actorFor +
_layerFor wires ActorSpec into ModelLayer; schema validates kind:model
and actor archetype; lint determinism gate covers actors/.
Gate: lint 107 files clean, 70 shader literals, 68 scenes green; vite
build 294 modules; ActorGenerator determinism + mesh smoke tests pass.
