Why teams trust the number
Metadata only. Grasp reads commit history and PR<br>events, never file contents. Hard evidence only. AI attribution counts co-author trailers<br>and bot accounts; we report it as a floor, not a guess. Honest limits. The Grasp Score is a<br>potential indicator. It tells you where to look, and we say so on every report.<br>No AI inside. Grasp itself uses no AI: every score is deterministic, reproducible<br>arithmetic over git metadata. Run it twice and you get the same number, and the raw data lets<br>you re-derive it yourself.
