- f4-w6-west-room-407-vault-membership: No separate room number is printed inside the vault; retain the relationship as conditional.
- f4-w6-west-door-handing-conflict: Inward swing is visible, but hinge/hand naming requires an agreed approach-side convention and remains null.

- 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.
- 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.

- 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.
