Original sheet identity has not yet been reconciled.
Extraction: Reviewed · extraction partial. Partial timed visual review: Partial sequential 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1265.webp after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Normalized access-image regions before rotation. Full fine-region extraction remains outstanding. 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: Typical section at window for Stairs A and C; existing B/D/E and handrail schedule evidence reused. Partial timed visual review: Upper-left typical A/C construction crop. Other common B/D/E and railing facts preserved in existing IMG1122/1123 packages. Partial timed visual review: B/D/E flight rail and landing-newel witness endpoint classes. Two crops; full physical height above tread remains unresolved. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.
Highlighted reading: [steel square tubing body and cast-iron profiled cap are separate callout components]. Material/profile boundary relationship only. Tube thickness and complete cap offsets remain uncertified; existing nominal4-in side reused.

Unresolved extraction work
- Partial locator only: review all fine dimensions, specifications, note regions and companion details
- Reconcile original linework with handwritten annotations/revisions
- Register physical instances, quantities, element dimensions and spatial relationships
- Remaining fractional dimensions and endpoint classes
- Host wall, opening, landing and component profiles
- Companion sheet registration and revision reconciliation
- Independent placement/model checking
- All unreviewed fabrication details and material-code cells
- Newel tube/cap profiles and connections
- W225/W226 storey-specific registration
- Independent overlay and fabrication checking
- Complete fractional dimensions and witness endpoint classification
- Installed instance registration and component quantities
- Companion details and handwritten revision reconciliation
- Independent modeling and checks
- 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
- Accepted rail-to-rail clear width, closed landing/slab-opening boundaries and headroom
- Complete material/gauge/fastener schedules, cap/moulding profiles and finish extents; remaining notes and revisions not fully reviewed
- Checked source-to-building transforms, storey/installed instance applicability and independent physical checks
- Complete rail/string/cap offsets, tread product and panelled-riser materials not certified
- 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.
- String cap/base offset fractions not reopened: prior native crop failed; clearer independent evidence is still required.
