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.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial locator review after catalogue/OCR of <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1110.webp. Primary lettering upright; no complete region review claim. Access-image normalized regions. No model geometry inferred. Partial timed visual review: Source-local printed evidence only; no accepted building transform, installed quantity, or reconstructed geometry. Prior verified measurements omitted; unresolved endpoints and companions 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: Text reuse only; gate spacing, bar dimensions, material and reversed Stair C applicability preserved in parallel-review-detail-stairs-20261012a.json. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Bottom note's 6′0″ maximum is readable but initial bracket wording remains photograph-edge clipped. Broad section-dimension question is not closed. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage.

Highlighted reading: 5/8" x 1/8". Upper lattice leader gives flat-bar width; paired thickness separately recorded.

Bottom note's 6′0″ maximum is readable but initial bracket wording remains photograph-edge clipped. Broad section-dimension question is not closed.
Complete fine dimension chains, rail/string/nosing profiles, fastener/gauge/material schedules and exact finish/rough endpoint classes remain partial.
Installed instance/storey assignment, source-to-building registration, closed slab openings, headroom and independent physical checks remain outstanding.
Companion W228 details and governing revision/installation applicability remain unresolved; source extraction does not approve model geometry.
Complete member/profile dimensions, fastener sizes, finish thicknesses and endpoint classes
Installed instance allocation, floor/terminal applicability and revision disposition
Companion W228/exposure reconciliation, source-to-building registration and independent physical checks
Complete fine chains, rail/stringer/nosing profiles, fasteners, material/finish extents and endpoint classes remain partial.
Installed quantities, closed landing/slab-opening boundaries, headroom, physical clear widths, source-to-building registration and independent checks remain unresolved.
Companion W228 and governing original/revision applicability remain unresolved; no accepted geometry or whole-source completion.
