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 sequential 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1206.webp after OCR/catalogue and reports. Actual clockwise reading rotation 0 degrees. Coordinates normalized access-image before rotation. No full-region extraction/modeling claim. Partial timed visual review: Additive bounded follow-up; coordinates normalized to unrotated access raster. Original plan/topology records retained. No model acceptance or complete-sheet claim. Partial timed visual review: Bounded text-first follow-up; ten sequential inspections total across nine derivatives including one W-6 same-source core crop. No accepted physical geometry. Existing verified readings omitted. IMG_1209 uses prior closeout text only. Partial timed visual review: Access ceiling note and master crop inspected; master reading orientation 270 degrees. Pit crop missed label and produced no depth reading. Partial timed visual review: undefined Partial timed visual review: Source-local partial review; no physical coordinates accepted. Partial timed visual review: undefined Partial timed visual review: Text reuse only: prior first-floor close-up package already contains selected heights/dimensions; no visual review or count-chain duplication.

Companion IMG_1206 shows an apparent 3-inch final digit on named POST OFFICE WORK space. Bounded reading remains unreviewed; retain prior f1-room-post-office-work-space-ceiling-height null (IMG_1202) separately and do not silently replace it. This label is not the public lobby height.
