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: Timed partial review of archive/folder-195/web/IMG_0903.webp; public derivative absent. Source upside down; rotated 180 degrees for reading. Regions below refer to original access-image orientation. Directly read Naturalization Clerk counter, Room 620. Specification close-up only. Partial timed visual review: Bounded source review; prior readings reused, every new property source-local and authoring-ineligible. No whole-image completion or installed quantity established. Partial timed visual review: Additive bounded detail review, 2026-10-11. Existing verified extraction reused; no building geometry accepted and no full-sheet completeness claim. Regions are normalized raw access-image coordinates before presentation rotation. Partial timed visual review: undefined
