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_1146.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 source-local followup of remaining legible annotations after OCR, queue and prior packages. Coordinates refer to unrotated derivative; no accepted installed geometry. Partial timed visual review: Normalized regions refer to unrotated derivative. Rotation records clockwise reading orientation; dimensions local to printed detail and do not establish installed world axes. Partial timed visual review: Selected new witnesses/clauses only; source remains incomplete. Partial timed visual review: Entry return and selected column/jamb offsets already exist. Broad remaining_column_return_chain question remains open; no duplicate glyph extraction.
Highlighted reading: 6". Printed source-local witness or object mark only. Column numerals are historical marks, not quantities; witnesses not converted to room geometry.
