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. Selected Main Street printed elevations and chain dimensions; Main entrance and flagpole parapet dimensions; one labeled Sixth Street entrance retaining-wall/ramp section as a site-wall construction witness. Partial timed visual review: Source-local photographed design detail; no installed quantity, accepted geometry or world placement authorized. Partial timed visual review: Source-local photographed drawing evidence only; stacked marks are interpreted as drawing references, not historical entrance identifiers. No installed quantities or accepted geometry. Partial timed visual review: Interior face of parapet looking toward Main Street; page-left/right only. Raw pixel content is upright despite stored EXIF 6. New readings are independent receipts, not silent corrections to prior package.
