ProofLine checks a maintenance work order against the photos a contractor sends. Each line of the work order gets a verdict: Supported, Not met, or Needs evidence, with the photo it relied on. When a photo can't prove a line, ProofLine doesn't guess. It asks for the exact photo it needs and re-checks only that line when it arrives. For repairs, it compares before and after photos, first checking they show the same place using fixed features like outlets and door trim. Every result is summarised in an email with the problems first. Under the hood it's an agent on a fixed call budget: when a verdict is unclear, it decides whether to look closer or call SAM 3.1 to find and count objects, then plain code checks every verdict, so nothing is marked done without real evidence. On 31 labelled test cases, 22 requirements weren't finished and none were marked done; all 39 verdicts matched an acceptable label.
