Designer work was reduced to explicit plan, room, asset, material, and presentation contracts.
PLANReference + scale
ROOMEditable geometry
STAGEAssets + materials
PROOFReview output
No designer-adoption claim
An add-on experiment showed that product-wide navigation and precision controls required ownership of the shell.
NEEDApplication-wide UX
SHELLBforartists fork
ENGINEReusable Python

A DXF or reference image becomes explicit scale, wall segments, opening markers, and typed room intent.
INPUTDXF / reference
SCALEMeasured / drawing
TRACEWalls + openings
RECEIPTIntent + warnings
Synthetic fixtures only
Room controllers generate their own geometry without taking ownership of furniture, cameras, or lights.
PARAMSRoom intent
GENERATEShell + trim
PRESERVEAssets + camera + lights
Bounded host smoke
Assets cross provider, rights, file, normalization, and provenance gates before reaching the workstation shelf.
SOURCEProvider / local
RIGHTSBundle / defer / reject
IMPORTScale + origin + names
Optional connectors remain bounded
Unit contracts, repository validation, and host scenarios produce a bounded room-to-render receipt.

System viewGenerated geometry has an ownership boundaryA rebuild may replace controller-owned children, but it must preserve furniture, cameras, lights, and other user-authored scene content.
