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 text-first then sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1238.webp. Selected legible source regions only, not full measured extraction. Coordinates normalized in unrotated access image; principal lettering upright. No model geometry authorized. Partial timed visual review: Source-local printed/observed section controls, independent local ceiling/roof and finish scopes; no building geometry approval. Partial timed visual review: Source-local architectural evidence only; no physical registration, installed quantity or accepted geometry. Existing verified measurements omitted; conflicting locator readings preserved. Partial timed visual review: D-D targeted conflict and reciprocal section-reference review; prior records retained. Partial timed visual review: Interior Section D-D local ceiling/light-well relationship. Raw pixel content upright despite EXIF 6. Prior room 606 transcription resolution reused.
