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.

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.
Source-pick both Room 402-side and corridor-side faces at the same stations, classify finish or construction boundaries, and independently verify the printed 4-inch witness connects those faces.
Pick the wall's two true terminations at its demising intersections; split it at the door with exact two-jamb coordinates and verify the opening width, head and threshold against a door schedule or detail.
Close reciprocal Room 402/corridor/Room 443 face and door topology, including more than one check of the 7-foot clear corridor witness.
Validate the frozen W-6 transform locally for classified physical faces and carry uncertainty into canonical X/Z coordinates.
Establish the wall's physical base and top from an applicable section, ceiling/slab detail or schedule; the 137.25 finished-floor datum and 11.5-foot story interval alone do not give wall height.

On registered W6/IMG_1212 and W7/IMG_1213, repick the same physical edge classes and closed floor-opening contours at Stair E; solve the W226 plan-to-canonical transform from non-collinear correspondences and check held-out edges and the adjacent-floor join before authoring one fourth-to-fifth-floor segment.

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
Each physical wall/room/opening still needs classified finish/rough/structural faces, closed boundaries, build-up, levels, installed quantity and checked building registration; source glyph closure does not supply these.
Exact finished/rough/structural/clear endpoint classes, closed boundaries and physical dimensions remain unresolved.
Installed quantities, construction build-up, fixture/material schedules, original/revision authority and companion applicability remain unresolved.
Source-to-building registration, datum continuity, independent checks and architectural acceptance remain unaccepted.
All remaining unreviewed notes, regions, callouts and schedules require further review.
