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 after catalogue/OCR of <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1116.webp. Primary lettering upright; no complete region review claim. Access-image normalized regions. No model geometry inferred. Partial timed visual review: Source-local printed evidence only; no accepted building transform, installed quantity, or reconstructed geometry. Prior verified measurements omitted; unresolved endpoints and companions retained. Partial timed visual review: Text/OCR, review-queue and prior-package audit; prior verified readings reused without duplication. No accepted geometry or building connections. Partial timed visual review: Additive selected-region review. Prior verified records reused without duplication; no accepted geometry. Partial timed visual review: Section A-A basement flights targeted; drawn tread counts are candidates, with calculated going withheld from physical authoring. Partial timed visual review: Selected fine closure only; not exhaustive source extraction. Partial timed visual review: Targeted basement-finish-label crop again contains no separately printed absolute elevation beside the label. Retain null; do not calculate 93.25 minus 15 as printed authority. Partial timed visual review: Text-only canonical/queue/OCR reuse; no new image inspection. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage.
