Can a Crew, a Model, and a Robot Agree on What a Rafter Is?

Three parties each describe the same roof, but none can read the others' description. The town assessor's record states asphalt shingle, average condition, built in 1962. A vision model analyzing satellite imagery and a street-level photograph claims it is a gable roof with moderate pitch, two planes, and a chimney interrupting the north side.
An estimator standing in the driveway says the roof consists of twenty-two squares, stick-framed with ring-shank sheathing nails, and likely plywood over original boards. All three parties are describing one assembly, but there is no shared vocabulary among them. Adding a crew with a crane or eventually a robot would make the situation worse, not better.
