Extraction: Reviewed · extraction partial. Partial timed visual review: Partial text-first and one sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1187.webp. Coordinates normalized to unrotated access image; clockwise correction given by rotationDegrees. Selected regions only, not full measured extraction. No modeling authorized. Partial timed visual review: Selected bounded crop only. Prior verified values retained. Partial timed visual review: Additive selected region follow-up; previously verified findings omitted. Dimension witnesses apply only to depicted source-local spans. Extraction partial; modeling not started.
Highlighted reading: Elevation of concrete floor = 79.70. Printed numeric source elevation resolved; source unit and numerical city-datum definition remain open. No modern elevation conversion.

Unresolved extraction work
- locator review only: all dense notes, dimension chains, utility marks and fine fractions need complete region extraction
- original survey datum, later annotations and revision authority reconciliation
- source-to-instance registration, quantities and companion construction details
- Remaining fractional dimensions, leaders and endpoint assignments
- Full regional notes and companion detail reconciliation
- Physical instance registration and quantities; no accepted model geometry
- Source elevation unit and numerical city-datum definition remain unresolved
