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_1110.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: Text reuse only; gate spacing, bar dimensions, material and reversed Stair C applicability preserved in parallel-review-detail-stairs-20261012a.json. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Bottom note's 6′0″ maximum is readable but initial bracket wording remains photograph-edge clipped. Broad section-dimension question is not closed. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage.
