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 text-first then sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1154.webp. Selected legible regions only, not full extraction. Coordinates normalized to unrotated access image; actual principal text upright. No modeling authorized. 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 source-local detail followup; existing verified readings retained. Sequential upright WebP review or explicit text-summary reuse; no modeling 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: Additive finish/fixture note review after prior records; fine detail limited by access derivative resolution; no geometry acceptance. Partial timed visual review: Selected source-local properties; source remains incomplete. Partial timed visual review: Whole access locator reused to navigate companion W234; no redundant previously measured leaf dimensions added.
