Proctor is a security-relevant tool: teams use it to decide whether to trust a change. If you find a way for a change to pass proctor in CI while hiding test tampering, and it's realistic enough to be abused, please report it privately through GitHub's private vulnerability reporting instead of a public issue.

Ordinary detection gaps (an agent cheat that proctor doesn't recognize yet) are not vulnerabilities. Please open a normal PR with the diff in tests/fixtures/cheats/.
