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.

Courtroom 612—detail view

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_0987.webp. Access-image normalized coordinates are unrotated derivative coordinates; rotationDegrees records clockwise correction needed for readable text. No model geometry authorized by this evidence. Partial timed visual review: Text-only reuse of documented master-exposure blur; reopening the same blurred chain would add no evidence. Sharper IMG0986 is not used to close IMG0987-specific questions. Partial timed visual review: Additive remaining-region review; source regions use original access derivative coordinates. Reuse prior verified evidence; preserve conflicts separately. No physical geometry inference. Partial timed visual review: Reused prior source-quality review; no additional image inspection because clearer companion IMG_0986 was available. No duplicate dimensional readings. Partial timed visual review: undefined

Highlighted reading: ½"=1'-0". Selected visible source evidence; partial review. Applies only to depicted assembly, not whole building.

Unresolved extraction work

all small dimensions and marginal notes
full-sheet completeness and companion reconciliation
floor/room registration where not explicitly printed
This exposure's original and orange chain remains illegible; no collection-wide irrecoverable-gap declaration.
Companion chain and revision authority remain open.
Remaining dimensions, notes, schedules and companion details outside this bounded review remain open.
Physical room/floor/instance registration and historical issue authority remain unverified; no geometry or whole-source acceptance.
Untranscribed fine dimension chains, fraction readings and profile endpoints require source-resolution crops.
Physical room/floor/instance registration and companion details remain unreviewed.
Extraction partial; modeling/checking unchecked; no geometry acceptance.
Exposure-specific blur is a source gap; collection irrecoverability not established
illegible: local original white and orange revised dimensions in this exposure
awaiting-companion: IMG0986 same-sheet chain and full-size details
unreviewed: whole-source coverage and historical authority
