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 locator review: catalogue/OCR searched before sequential inspection of one <=1000px JPEG65 derivative from public/archive/drawings/complete-upright/IMG_1121.webp. Selected visible regions only, not full measured extraction. Coordinates normalized to unrotated access image; principal lettering upright. No modeling authorized. Partial timed visual review: OCR, queue and existing extraction packages searched first. One sequential upright WebP inspection; only additive selected properties recorded. Previously verified readings reused without duplication. No complete extraction or accepted geometry. Partial timed visual review: OCR and existing text packages searched before one sequential upright WebP inspection. Additive region review; existing verified properties reused, not copied. No accepted geometry or cross-floor connection. Partial timed visual review: H first-floor plan numbered flight bands and landing arrangement; F sixth/seventh floor scope confirmed. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Selected fine closure only; not exhaustive source extraction. Partial timed visual review: Text-only canonical/queue/OCR reuse; no new image inspection. Partial timed visual review: undefined Partial timed visual review: undefined
