AI slop detection
Catches boilerplate in PR bodies, commit messages, and changed comments.

Rules with receipts.

Included with Critique - standalone ready - open-source version coming soon
Run it before reviews, or run it alone.
Checkpoint lives inside the same GitHub App and dashboard. It can protect credits for Critique review, or operate as a cheap contributor gate for repos that only need deterministic intake.
