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.
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.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
Printed source-local detail evidence only; no accepted room geometry, installed quantity or placement. Floor and room assignments follow printed labels.
Drawing notation: BRONZE PLATE
Printed source-local detail evidence only; no accepted room geometry, installed quantity or placement. Floor and room assignments follow printed labels.
Printed source-local component or finish evidence only; no installed quantity, placement or accepted geometry. Nominal nipple sizes are not outside diameters.
Drawing notation: TRANSLUCENT GLASS PANELS
Printed source-local component or finish evidence only; no installed quantity, placement or accepted geometry. Nominal nipple sizes are not outside diameters.
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level.
Drawing notation: THUMB NUT; TOP REMOVABLE FOR RELAMPING
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level.
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level.
Drawing notation: STANDARD PORCELAIN RECEPTACLE
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level.
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level. Review correction review-correction-20261014f-p18-back-construction: Same original P18 back note reads HEAVY GAUGE BRONZE BACK, not CASTELLATED. Derivative inventory, generation/copy scripts and matching hashes independently establish raw-to-access clockwise90 mapping (1-y,x), not EXIF inference. Old access rectangle maps raw[.43,.09,.77,.44] within new crop; observed label falls within old rectangle. Original text retained as historical extraction. HEAVY GAUGE supplies no numeric thickness/gauge, revision selection or accepted installed geometry.
Drawing notation: HEAVY GAUGE CASTELLATED BACK
Selected source-access normalized region; printed/type-local property. Nominal pipe/casing sizes are not measured outside diameters. Assignment labels establish intended type use only. Source access orientation recorded at image level.
Printed type/component specification only; no installed selection, quantity, world geometry or governing revision. Exact P18 section back witness. HEAVY GAUGE supplies no numeric gauge or thickness; BRONZE is material lettering, not process certification. Earlier CASTELLATED wording retained for primary curation.
