Sheet W224
Extraction: Reviewed · extraction partial. Typical lower stair plan and sections A-A/B-B: flight widths, numbered 9+2+9 arrangement, going, landing spans, selected materials and seventh datum. Read column reference marks 82/68, 1′4″ horizontal offset, and 9′0″ TO CL COL82 ordinate; face endpoints remain unresolved. Entry leaf size and swing, nominal 4-inch ordinary-floor partition, and offset witness semantics; no exact finished-face insertion. Stair D W224/W-6 fourth-floor placement comparison; no accepted insertion or opening polygon. Partial timed visual review: Existing W224 detailed packages reused as text only; no source inspection or new measurement. Outstanding roof/fan-room regions, rail/newel, thickness and registration retained. Partial timed visual review: Text/OCR, review-queue and prior-package audit; prior verified readings reused without duplication. No accepted geometry or building connections. Partial timed visual review: Additive selected-region review. Prior verified records reused without duplication; no accepted geometry. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. 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: New section A-A local notes/witnesses do not settle the uncertain tread-material abbreviation, finish/core planes, headroom, profiles or any world-transform question. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage.
Highlighted reading: Hinge at page-upper jamb; leaf swings inward toward stair landing. In type axes the hinge is at the smaller-v jamb; the open leaf projects toward -u. No numeric jamb station is inferred.
