Verify it yourself

An agent proposes an action. OmegaEngine scores it, decides, and seals the decision with a tamper-evident signature. Evaluate one below — then edit the sealed envelope and re-verify.

This page runs entirely in your browser with a public demo key, so you can tamper freely. In production the signature is computed with a server-held secret you never receive — so an edited or forged decision can never produce a valid signature. Same canonical-JSON + HMAC-SHA256 mechanism as the live engine.
