The published design
“The blending of color and texture by using various materials give the ‘Carlton’ an appearance all its own. The interior arrangement is very practical and consequently proves highly acceptable to the housewife. Asphalt shingles are used on the roof.” — Home Builders Catalog, p. 642 (1928). 6 rooms, bath and sun room; blue-print working plans sold for twenty dollars.
Our model of the published plan, graded by the independent evaluator across 2 floors— it shares no code with our generator, so it isn't grading its own homework. Read from an AI vision pass at 80% confidence; the model is approximate.
Replication fidelity — measured against the published drawing
Scored floor-by-floor against a transcription of the source sheet (room set, door graph, area shares, interior dimensions) — gated in CI so it can't silently regress. Compare for yourself: the published drawing ↗ (Public Domain Mark 1.0 (published 1928, US)).
Ground floor29×23.15 ft · 5 rooms
SunRoom (10′×13′) projects from the left of the main block — the tiled model shows the rectangular core true to the plate; the Reproduction and Source underlay views draw the wing in place. Full polygonal-envelope support is on the engine roadmap.
Auto-generated wall-first reproduction seeded from the AI read — NOT yet human-verified; the amber score is its honest ink match. The refine loop and the review queue improve it.
