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_1265.webp after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Normalized access-image regions before rotation. Full fine-region extraction remains outstanding. Partial timed visual review: Text-first OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null. Partial timed visual review: Typical section at window for Stairs A and C; existing B/D/E and handrail schedule evidence reused. Partial timed visual review: Upper-left typical A/C construction crop. Other common B/D/E and railing facts preserved in existing IMG1122/1123 packages. Partial timed visual review: B/D/E flight rail and landing-newel witness endpoint classes. Two crops; full physical height above tread remains unresolved. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.
