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.

Broadway 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. Reuse of existing text/registered property data only; no new image review. Main upper wall corners and visible floor datum courses. 69 previously identified Broadway opening instances, individually repicked visible envelopes. Main coping/parapet/cornice/frieze/F3 belt envelopes. Basement dashed windows, sidewalk/finish-grade guide lines, visible boiler reference. Text-first physical-pilot gate 3 audit; existing reviewed plan, elevation and section records reused without reopening an archival image. Page-right 4/11 metric/cardinal conflict audit; Existing B02 visible elevation envelope, master pixels about x1199–1298/y1311–1437; opening mark was not independently decoded from this elevation. Page-right 4/11 metric/cardinal conflict audit; Existing B09 visible envelope, master pixels x2763–2864/y1318–1444; metric alternative only, not a confirmed key match. Page-right 4/11 metric/cardinal conflict audit; Right-end street label fixes right as south/Madison. 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. Partial timed visual review: Bounded target crop inspection; source-local printed/observed evidence only.
Highlighted reading: 127.7773 ft (provisional trace).

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.
- Remaining details and notes
- Vertical stone-face continuation and local projections
- Full wall construction thickness
- Architectural reveal/window sections
- Sheet number/titleblock and all drafting notes/details not exhaustively transcribed.
- Circled window/type marks not reliably legible at bounded review; preserved as null.
- Coping ornaments, pilaster capitals/fluting, sash subdivision, hardware and grille ornament not metrically extracted.
- Lower opening portions obscured by railings/terraces have not been reconstructed.
- No detail-sheet closure, wall section or accepted masonry profile.
- No independent horizontal control check on this elevation.
- Identify exact Broadway wall face against plan witness lines and derive X offset.
- Resolve exterior finish face versus column/wall witness and local pilaster projections.
- Extract story-dependent wall thickness and setbacks.
- Resolve cornice, parapet, belt and lower-base projection depths from details/sections.
- Determine rough masonry versus frame versus clear opening boundaries.
- A W-6-to-world registration solved from classified, source-picked controls with held-out plan residuals.
- A page-right/west/Broadway W-6 chain with exact grid/column identifiers and a resolved end-chain transition.
- A direct plan key tying one W-6 room/opening instance to opening-broadway-F4-B05/broadway-bay-05.
- A face bridge from the W-6 room-side exterior-wall trace to W403's exterior FACE OF STONE, without assuming wall thickness.
- A classification of the IMG_1231 visible opening envelope as the same jamb/masonry/frame boundary measured by W-6.
- One held-out horizontal plan/elevation control with independently known station and comparable endpoints; report its residual and tolerance.
- Review acceptance of the B05 elevation envelope host and station origin; acceptedHostElementId and acceptedStationFeet must become non-null.
- Independently decode IMG_1231 fourth-floor opening keys at both B02 and B09 and the relevant W207 orientation/detail mark.
- Read the W-6 grid names bounding Room 421/4/11, with source-picked axes and a withheld same-class plan/elevation station check.
- Classify exact plan and elevation opening edges as masonry, finished jamb, frame, sash or clear aperture before comparing width residuals.
- Tie the W403 outside FACE OF STONE section to the corrected bay and obtain the opposing interior face and complete layer chain.
- 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.
- Rooftop notes and accepted face/roof construction layers
- Unique W207 bay correspondence and historic opening boundary classes
- Grille/stone/grade details and regional station correspondence
- All held-out station checks, revisions and wall-face registration
- Exact dimensions and witness endpoints not fully extracted
- Companion-detail, revision and floor/room registration unresolved
- All-region review and modeling acceptance incomplete
- Roof-superstructure terra-cotta/copper notes do not establish material or projection depth of main cornice, parapet/frieze bands; all window/frame/clear-width nulls remain open. highpoint-to-coping fractional discrepancy not re-reviewed.
- Classified finished/rough/masonry/frame witness endpoints and installation registration remain unresolved.
- Companion drawings, original/revision authority and as-built applicability remain unresolved.
- Complete remaining notes, courses, profiles, opening construction and whole-source/model acceptance remain outstanding.
