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.

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.

Sheet number unresolved
Extraction: Reviewed · extraction partial. Sheet title; Section C-C; Main entrance HALF PLAN; Bronze rail note and pier fixture Partial timed visual review: Source-local photographed design detail; no installed quantity, accepted geometry or world placement authorized. Partial timed visual review: Source-local photographed drawing evidence only; stacked marks are interpreted as drawing references, not historical entrance identifiers. No installed quantities or accepted geometry. Partial timed visual review: Main Section C-C step material and companion reference. Known count/run/slab/elevations reused; no step profile inferred from symbolic sawtooth. Partial timed visual review: Section C-C and upper HALF PLAN. Raw pixel content upright despite EXIF 6. Stair count/run/datum values reused; additional slab evidence distinct from tread/riser profile. Partial timed visual review: Half-plan local source dimensions. Raw encoded pixels read upright at zero rotation despite parent EXIF 6; EXIF is not used as reading transform.
Highlighted reading: 23.

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.
