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.

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.

Sixth Street elevation
Original sheet identity has not yet been reconciled.
Extraction: Reviewed · extraction partial. Partial: façade opening identities/counts and selected printed datums. Drawing number, registration and opening dimensions still unresolved. Partial timed visual review: Text-only prior evidence inventory; catalogue labels are discovery-only and prior verified identity retained. Partial timed visual review: Source-local architectural evidence only; no physical registration, installed quantity or accepted geometry. Existing verified measurements omitted; conflicting locator readings preserved.
Highlighted reading: 1 opening. Opening envelope visually identified. Image station is not a physical distance; dimensions remain unresolved.

Unresolved extraction work
- Physical plan registration: No readable horizontal station chain or overall width occurs in the three assigned full elevation photographs. All station_ft, width_ft, height_ft, sill/head values remain null. Register traces to separately extracted foundation/floor-plan controls before 3D physical placement.
- Main full-elevation count: Assigned IMG_1241 is a lower corner crop. Inspect candidate full Main source separately; archive index titles may be wrong.
- Sheet numbers: Title blocks omitted or cropped in assigned views. Sheet numbers cannot be responsibly invented from image sequence.
- Upper level variation: Left-edge F7 chain is 171.75; Madison upper-opening reference is 173.75. Preserve both; do not impose a single universal F7 floor slab. Ambiguous secondary annotation on IMG_1233 not used as separate numeric measurement.
- Main second-floor label conflict: IMG_1241 prints 125.75 at both second and third floors. Its 21′0″ and 11′6″ chain and IMG_1233's explicit second114.25 contradict the second-floor label.
- Opening dimension schedules: OCR identifies IMG1250–1252 as upper-story Broadway details, IMG1253–1254 as heavy-type casement windows including basement/penthouse sash. These have not been visually measured in this bounded pass. No exact opening width/height can be inferred from elevation scale alone.
- Lower envelope and attachment profiles: OCR/index companions identify lower elevations/grilles, balustrades, steps, Broadway/Madison entries. Numeric profile projections remain null pending these details.
- Rooftop and small ancillary openings: Main-volume counts exclude rooftop stair/penthouse openings, vents, grille subpanels, door leaves, and facade lighting. Separate records required for an exhaustive whole-building object inventory.
- Sill/head datums: The drawn opening rectangles support approximate image bboxes only. Floor datums are not opening sills or heads. Do not replace missing sill/head values with floor lines.
- Unreadable minor marks: Some parapet/grade spot levels, window schedule circles, and faint marginal annotations remain unreadable within the four-full-image/eight-crop visual budget. This dataset is a bounded extraction, not a claim that every number in the archive has been transcribed.
- Finished/rough/structural boundary classes and physical source-to-plan registration remain unaccepted.
- Remaining fine dimensions, all material/finish schedules, notes and historical revisions need regional and companion review.
- No installed quantity, geometry, as-built state or architectural release is accepted.
- Unclear secondary upper annotation, parapet and roof notes
- All classified opening edges, material profiles and schedule crosswalks
- Retain existing printed floor properties; no chain re-extraction
- Spot-grade glyphs, wall layers, sheet identity and revision authority
- Exact dimensions and witness endpoints not fully extracted
- Companion-detail, revision and floor/room registration unresolved
- All-region review and modeling acceptance 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.
