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 catalogue/OCR-first then sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1331.webp. IMG_1322 additionally has one 250x435 post-schedule crop. Regions normalized in unrotated access-image coordinates; rotationDegrees is clockwise correction. Selected evidence only, no full extraction/modeling. Partial timed visual review: 2026-10-11 remaining-region review. Prior queue, OCR and packages reused; ten sequential inspections total, confined to IMG_1329/1334/1336/1337. Normalized regions in unrotated complete-upright WebP. Research only; no accepted geometry or complete extraction. Partial timed visual review: OCR and prior package text review only this pass; no new visual verification. Partial timed visual review: Additive source-local review; normalized coordinates in unrotated 2200×1650 access WebP. Reuse previous verified records; no accepted geometry or complete extraction. Partial timed visual review: Additive source-local lighting review; source regions normalized in unrotated access-image coordinates. Printed numbers are preserved separately from fixture types. No world coordinates, complete extraction or installed acceptance. Partial timed visual review: undefined Partial timed visual review: New readings use raw 4032x3024 master-image coordinates, ignoring EXIF. Regional identities are modern extraction IDs, not historical identifiers. No accepted installed transforms or building geometry. Partial timed visual review: undefined Partial timed visual review: Bounded additive source review. Printed schedule quantities and source-local apparatus detail dimensions do not establish installed building geometry. Partial timed visual review: undefined
