The measured building.

Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial text-first sequential locator review using <=1000px JPEG derivative of public/archive/drawings/complete-upright/IMG_1226.webp. Access-image normalized regions before rotation; rotationDegrees is clockwise turn required for primary lettering. Locator coverage does not mean complete regional extraction. No modeling. Partial timed visual review: Sequential 2200px WebP review; additive selected remaining properties only. No geometry acceptance. Partial timed visual review: Selected additional source-local property review; normalized regions reference unrotated access derivative; no metric transform. Partial timed visual review: Selected source questions and verified prior property crosswalk only; no exhaustive region or source completion claimed.

Highlighted reading: 8′-8″. Horizontal printed span between inner stair enclosure sides; not flight width or accepted slab opening.

cropped or faint evidence and companion sheets
Remaining dimensions and endpoint classification
Materials, schedules and companion details not yet completely reconciled
Accepted source registration and geometry checking
Closed geometry and finish/rough/structural endpoint classification
Complete quantities, schedules, companion details and revision reconciliation
Accepted source registration and held-out geometry checks
Exact finish/rough/structural endpoints and closed physical boundaries remain unresolved.
Complete opening/fixture quantities, schedules, companion details and historical revision authority remain unresolved.
Source registration, installed condition, clear heights and held-out geometry checks remain unaccepted.
All other unrecorded regions, fine dimensions, notes and callouts require further review.
No new visual source reading in this pass; prior fine numeric chains and geometry questions remain open.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
