The measured building.

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.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

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 sequential 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1257.webp after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Normalized access-image regions before rotation. Full fine-region extraction remains outstanding. Partial timed visual review: Printed specification or source-local detail only; no installed quantity, accepted room geometry, host placement or building transform established. Partial timed visual review: undefined

Highlighted reading: 3/16" STL PLATE. Printed specification or source-local detail only; no installed quantity, accepted room geometry, host placement or building transform established.

Unresolved extraction work

Partial locator only: review all fine dimensions, specifications, note regions and companion details
Reconcile original linework with handwritten annotations/revisions
Register physical instances, quantities, element dimensions and spatial relationships
Remaining small dimension fractions, profile boundaries, fasteners and dense notes require targeted master/clearer companion review
Installed instances, quantities, room registration and revisions remain unresolved
All-region measured extraction and architectural acceptance remain incomplete
Complete door dimensions, yoke/strap sizes, hinge/gauge details and meeting-stile profiles remain open.
Whole-sheet mesh/shelf/pit question remains open; this crop covers the mailing-door family only.
Opening-specific deployment and original/revision authority unresolved.
Remaining regional dimensions, notes, schedules, fasteners and companion details are not fully extracted.
Original/revision authority, installed instances, quantities and room/floor registration remain unresolved.
Source-local evidence is excluded from model authoring and architectural release.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
