Paired on the measurement’s name only, which cannot know that three span lengths sum to the deck length. Step 3 works these out properly for every item it matches — reading every crop behind the item, deriving what the drawings imply and showing its arithmetic. This item has not had that pass yet; the button runs it for this one.

  "description": "This crop is a schematic construction clearance diagram showing a rectangular envelope 22'-0\" wide, split into two 13'-0\" halves about a vertical track centerline. A leader identifies the 'top of high rail' location within the envelope. The diagram is noted as 'NO SCALE' and appears to define required clearance limits relative to a rail track centerline."

  "description": "This crop is a detail titled 'CONSTRUCTION CLEARANCE DIAGRAM' (no scale) showing a rectangular clearance envelope around a railroad track. It gives an overall vertical dimension of 22'-0\" and horizontal dimensions of 13'-0\" on each side of the track centerline, with callouts identifying the track centerline and the top of high rail. It appears to define the required minimum construction clearance envelope around an existing rail line, related to the vertical clearance notes for the bridges described elsewhere on the sheet."
