Give the room a reason.
Design the view on entry, a recognizable landmark, a required route and an optional discovery. Compare architecture from the current model with an authored procedural baseline. The retrained model uses eight design families. Four whole families remain held out.
Composition
Composition v3 keeps the same 424 → 96 → 2 network. It trains on 800 controlled variations from eight families, with 192 same-family validation rooms and 256 rooms from four held-out families. Explicit checks reject proposals that miss the view, density or route requirements; fallback is labelled. Family reference knows the selected grammar; the procedural baseline selects only training grammars.
Design intent
Eight families are used in training and four remain held out by family, rather than by seed. A draft is saved on this device only when you choose Save. Exports keep geometry provenance and annotations together.
