The measured building.

printed_width_candidate

39 in

Opening annotation candidate; paired-leaf versus single-leaf width and jamb endpoints unresolved. Review correction review-correction-20261014b-detail1011m-1205-detail1010-f1-mailing-platform-vestibule-opening-middle-printed_width_candidate: Same IMG1205 upper middle platform/vestibule diagonal glyph reads3'-2 x7'-10, not3'-3. Independent native strip and expanded host witness distinguish this from the already verified lower mailing/workspace annotation. Earlier39in retained; correction proposed only. Numeric glyph withdrawal only; prior value/notation/unit stay historical and no physical geometry or governing revision is selected.

printed_height_candidate

94 in

Opening-label height candidate; do not apply to all three openings or accept physical geometry.

fractional_reference_mark

Preserved printed reference candidate; not room number or assumed historic door ID. Denominator needs schedule crosswalk.

leaf_symbol_count

2 count

Observed symbol count at this opening only; not installed quantity or width. Double arcs extend to both sides of the partition, a double-acting candidate.

host_relationship

Opening interrupts the shared platform/vestibule boundary; exact jambs and partition construction remain unresolved. Fractional type marks preserved for later close crop rather than invented door or room numbers.

opening-middle-literal-reference-mark

Literal circled numerator/denominator reference mark above same paired opening. Do not interpret as a length, quantity or historical room number. Source-local original-layer witness only; no installation, quantity or geometric acceptance.

opening-middle-platform-vestibule-host

Observed original-layer opposed swing symbols in common boundary separating labeled platform above from labeled vestibule below. Source-local adjacency; no exact opening width, topology transform or room geometry. Source-local original-layer witness only; no installation, quantity or geometric acceptance.

upper-middle-opening-width-resolution

38 in

Upper middle diagonal annotation between platform and vestibule, beside mark1/29; distinct from lower mailing/work-space3'-2 label. Printed2 is independently re-read in both targeted strip and expanded host crop. Pair versus leaf and finished/rough faces remain unresolved. Source-local original-layer witness only; no installation, quantity or geometric acceptance.

upper-middle-opening-height-resolution

94 in

Height component of upper middle paired-opening annotation only. Source-local original-layer witness only; no installation, quantity or geometric acceptance.
