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.
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.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass review from catalogue/OCR then one 1000px JPEG locator derivative of public/archive/drawings/complete-upright/IMG_1084.webp. Regions normalized in unrotated access image; actual principal text is upright (0 degrees). Small blurry values remain unresolved; no modeling authorized. Partial timed visual review: Source-local additive detail review; no installed quantity, accepted room geometry, physical placement or wall cuts established. Partial timed visual review: Source-local Construction No.14 expansion-joint fabrication; dimensions not transferred to roof geometry. Partial timed visual review: Printed source-local type/component or section control only; no accepted physical geometry, installed quantity or world registration. Original layer retained separately from revisions. Partial timed visual review: Previously verified rod fractions reused. This crop does not independently supply inch marks for rod designations; no numeric-unit closure. Partial timed visual review: undefined
