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.

Architectural ornament study for the U.S. Courthouse

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass review of public/archive/drawings/complete-upright/IMG_1021.webp after catalogue/OCR and existing observations. Coordinates are normalized access-image coordinates before rotation. Actual reading rotation 270 degrees. Foreground drawing only. Partial timed visual review: Additive source-local follow-up after queue, OCR and prior packages. Coordinates use unrotated access image; actual clockwise reading correction recorded. Existing verified readings reused without duplication. No physical geometry or completion claim. Partial timed visual review: undefined Partial timed visual review: Prior canonical evidence and standard region inventory crosswalk only; source not reopened in this batch. Partial timed visual review: undefined

Transcribe remaining faint dimensions and small callouts
Review full sheet and companion detail relationships
Reconcile handwritten dates/revisions separately from original drawing
Register to physical building instances; quantities not established
Full fine-dimension/profile endpoint extraction remains incomplete
Physical instance, floor and room registration unresolved
Companion sheets, revisions and installed quantities require reconciliation
Original versus revision authority and installed/as-built applicability unresolved.
Installed quantity, floor/room host, anchors and accepted source-to-building transform unresolved.
Remaining fine dimensions, schedules, notes and companion sections require review; modeling unchecked.
Installed placement, floor/room, count and revision authority
Remaining exact profile dimensions and unreviewed notes
Installed source-to-element assignment, floor/room and quantity verification
Governing issue/revision authority and remaining companion details
Checked-field date, signature identity and marginal annotation purpose remain unresolved

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.
