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.

Basement plan—Post Office storage and court exhibits

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Independent registration, named and numbered room/core locations, coarse boundary traces and selected visible door relationships. Partial timed visual review: Additive bounded follow-up; coordinates normalized to unrotated access raster. Original plan/topology records retained. No model acceptance or complete-sheet claim. Partial timed visual review: undefined Partial timed visual review: Source-local partial review; no physical coordinates accepted. Partial timed visual review: undefined Partial timed visual review: Basement Stair C / Elevator 2 wrapper and selected local witness, not a complete basement extraction.

Highlighted reading: 35.4731 ft (trace). Manual source location in the explicitly stated upright reference. Metric geometry is a provisional trace, not a printed dimension.

Unresolved extraction work

All dimensions and notes
All wall thicknesses/materials
Door/window schedules
Physical slab edges and openings
Every room clear dimension
All stair/shaft vertical details
Regional levels and complete cross-sheet coordination
Every remaining dimension, schedule, callout and companion detail needs region review; no accepted physical/world geometry.
Source-local applicability, construction thicknesses, complete object inventory and as-built correspondence remain unresolved.
Exact installed quantities and type-to-instance assignment
Rough/finished/structural endpoint classes, complete host outline and source-to-building registration
Governing original/revision and companion-detail authority; no accepted physical geometry
All uninspected source regions, notes, schedules and companion details; whole source remains partial
Accepted finish/rough/structural endpoint classes and source-to-building transform absent
All physical construction layers, exact material limits, installed quantities and as-built correspondence unresolved
Remaining fine chains, schedules, callouts, revisions and companion details require review; exhaustive extraction not certified
Classified finish/rough/structural faces, closed boundaries and source-to-building registration
Original/revision authority, companion details and as-built correspondence
All unreviewed regions, notes, schedules and callouts; no whole-source completeness
Full basement room/opening dimensions, boundaries and levels remain unresolved; no generic glyph can close these.
Accepted source-to-building transform and like-for-like finished/rough/structural face classification
Exact closed slab opening, landing perimeter and headroom
Construction/rail/nosing detail and revision/as-built reconciliation
All remaining unreviewed regions, notes, schedules and companion details
