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 using <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1153.webp. Lettering upright. Regions are original access-image normalized coordinates. Locating a region does not claim full review of its fine detail. No modeling. Partial timed visual review: Additive bounded remaining-region review of upright WebP after queue, OCR and prior packages; no geometry acceptance. Partial timed visual review: Additive targeted review; source-local details only. No installed quantities, finished room geometry or model acceptance established. Partial timed visual review: Prior finish/material/fixture text findings reused; source not reopened and no duplicate properties added. Partial timed visual review: Source-local view inventory and selective notes/individual properties; repeated-photo correspondence does not establish revision equivalence, installed quantity or exact geometry. Partial timed visual review: Selected source-local properties; source remains incomplete.
