Sheet W224
Extraction: Reviewed · extraction partial. Bounded duplicate-source review of W224's ordinary third-through-sixth-floor Stair D plan and its two placement witness chains. Partial timed visual review: Text-first OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null. Partial timed visual review: Whole access locator inspected to confirm reading orientation; diagnostic placement and fan-room acoustic evidence reused, no duplicate properties added. Partial timed visual review: Text reuse only: prior verified evidence retained without duplication; no new visual review or completeness claim. Partial timed visual review: Text reuse only: preserve existing verified stair counts/width controls and unresolved endpoint classes without new visual review or duplicate numeric readings. Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.
Highlighted reading: 6'-1 1/4" ON 6TH FL.. Alternate W224 photograph. Printed controls and the sixth-floor landing exception are corroborated; every candidate building transform remains conditional on explicit column and wall-face offsets.

Unresolved extraction work
- Independent proof that Columns 82 and 68 lie exactly on the candidate framing-line coordinates rather than at nonzero connection offsets
- Rough-wall versus finish-wall classification for the 1-foot-4-inch witness endpoint
- Exact wall line referenced by the 9-foot ordinate
- Reconciliation of the non-closing provisional fourth-floor trace and the residual fifth-floor trace
- Rough-versus-finish classification and independent plan reconciliation of the 4-foot-4-inch sixth-floor wall-witness variant
- Accepted host wall, entry jamb, threshold and slab-opening geometry
- Printed individual riser heights, construction thicknesses, stringers, rails, nosings, headroom and landing support
- Remaining fractional dimensions and endpoint classes
- Host wall, opening, landing and component profiles
- Companion sheet registration and revision reconciliation
- Independent placement/model checking
- Non-closing plan traces and column/wall endpoint reconciliation
- Host opening and threshold geometry
- Full fabrication extraction
- Independent model checking
- Complete fine dimension chains and classified rough/finish endpoints
- Source-to-building registration, landing polygons, slab openings and installed instances
- Companion detail/revision authority and independent physical checks
- Rail-to-rail clear width and rough/finish face classification remain unaccepted
- Closed landing/slab-opening boundaries, physical elevations and headroom
- Checked source-to-building transform and installed instance applicability
- Full unreviewed notes, fine profiles, connections and revision authority
- Complete fine dimension/profile chains, fasteners, connection details, material and finish extents remain partial.
- Installed instances, floor applicability, governing revisions, closed landings/shaft boundaries, headroom, accepted registration and independent physical checks remain unresolved.
- No pending source-reading IDs does not mean exhaustive review; unrecorded notes, profiles and structural interfaces still require coverage.
