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.

Sheet W208

Extraction: Reviewed · extraction partial. Targeted W208 companion review decoded repeated 6/10 and 7/10 marks at the Main/Broadway corner condition. Partial timed visual review: Printed specification or source-local detail only; no installed quantity, accepted room geometry, host placement or building transform established.

Unresolved extraction work

Whole-sheet notes, material codes, revisions and callouts remain partially reviewed
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

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.

Unique opening match gate

RETRACTED — 4/11 to B02 conflicts with oriented W-6 plan

The W207 4/11 and adjacent 4/12 marks remain verified printed readings, but the earlier assignment of 4/11 to elevation B02 is retracted. W-6 independently prints 4/11 on the Broadway/page-right strip near Madison/south; its north arrow points page-bottom. The W-6 position conflicts with B02 near Main/north. B09 is only a nearby station candidate, not an accepted identity.

Transfer of the separate B05 diagnostic geometry to the W207 target

PROHIBITED — no elevation bay is accepted for 4/11

The B05 horizontal-placement packet is a separate diagnostic built before the W207 split circle was decoded. Its provisional station, traced envelope and candidate wall host do not describe the W207 4/11 instance and must not be copied to B02.
