PromiseProof Verify · Judge Mode

Re-derive the verdict yourself.

A user turned activity-based personalization off. This page runs the same frozen, deterministic evaluator the repository ships, right here in your browser, with no network call, over the recorded evidence. It says PASS. Now tamper the evidence and watch the same evaluator return a broken promise, while the report you sealed a moment ago refuses to reproduce.

The AI that repairs the promise never owns PASS. An unchanged evaluator does, and you are about to run it.

You do not have to take our word for it. Run the check yourself, right here, in a few clicks. No sign-up, no setup.

This verifier is interactive and needs JavaScript. The same deterministic evaluator, evidence, and reports are in the GitHub repository, and a plain-language summary is on the overview page.
