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. Text-first review followed by one complete upright source and sequential crops from the same photograph. Reviewed title block, intermediate-landing plan, Sections A-A/B-B/C-C, gate detail, railing detail and major finish/component callouts. A later sequential Section A-A crop verified the depicted two-flight basement-to-first topology, three-flight first-to-second topology, associated landing counts, handrail-at-beam brace, flush wood block, terrazzo-floor/marble-base interface and unplastered basement joint. Duplicate/companion photographs IMG_1115 and IMG_1116 were identified but not opened. Partial timed visual review: Text-first OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null. Partial timed visual review: Section A-A basement-to-first independent tread recount. Two crops; upper dashed/hidden portion remains a candidate. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Selected fine closure only; not exhaustive source extraction. Partial timed visual review: undefined Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.

Top overall intermediate-landing plan source witness. Covers multiple flight/landing intervals; endpoints are exterior witness projections and not rail-to-rail clear distance. Review correction review-correction-20261013e-w225-plan-top: The targeted IMG1262 master re-read corroborates the previously recorded IMG1117 15ft9in witness.
