Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

- Bugs in production
- Unexpected behavior
- Performance problems
- Build failures
- Integration issues
