Accuracy was the thing we spent the most time on. The AI
extracts quantities from the blueprint and flags anything
ambiguous for review — you still review the output before
sending. The goal is catching the things that get missed when
a human is on hour six of a manual count, not replacing the
estimator's judgment.
