Object: Elevator No. 3 hatch/enclosure opening candidate
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.

horizontal_hatch_or_enclosure_witness
7'-4 1/2"7.375 ft
Dependency: Classify both endpoints and determine whether the witness is hatch-clear, car, rail, rough-enclosure, or finish-face geometry. Authoring eligibility: none. Source audit state: conditional.

vertical_internal_dimension_chain_segment_candidate
4'-7"4.583333 ft
The numeral is readable, but the property represented by the segment and its exact endpoints are not. It is not an overall hatch depth. Dependency: Classify the apparent outer/inner face at one end. Dependency: Classify the central crosshair/reference at the other end. Dependency: Confirm this is not a car, rail, or equipment offset. Authoring eligibility: none. Source audit state: conditional.

vertical_clear_hatch_or_shaft_depth
UnresolvedNumeric value unresolved
No sum is calculated from the visible 4'-7" segment because the complementary value and endpoint continuity are unresolved. Dependency: Securely transcribe either a single overall dimension or every segment in a demonstrably continuous endpoint chain. Dependency: Classify both terminal faces. Dependency: Confirm clear-hatch/shaft applicability. Authoring eligibility: none. Source audit state: unresolved.
