1 SET JAMBS ... DRS 3-0 × 7-0 1¾ THK ... MARK6037 ft
First jamb schedule row refers to door height; not overall jamb stock length. Other ditto rows require separate ownership review. Source-local witness/clause only; no physical instance, installed quantity, accepted geometry or original/revision installation authority established. Review correction officewitness1014d-unit-withdrawal-officewitness1014d-img923-mark603-door-height: Primary source-unit curation. Same-image original-layer numerical glyphs remain unchanged, but the earlier ft assignment was unsupported by securely observed unit marks or an independently verified unit convention. Withdraw the unit-valued interpretation while preserving original value/unit/notation/raw review history. New source record has unlabeled numeric glyphs, not a replacement measured dimension. Door row 3-0 ×7-0 /1¾ THK contains no securely observed foot/inch symbols; customary feet/inches decoding remains an explicit unestablished interpretation.
