WitnessOS in your browser
Fire governed actions, evaluate policy, and inspect signed receipts. The evidence ladder is real: this page demonstrates the same receipt structure the gateway produces, including the anchoring step where an RFC 3161 authority timestamps the record.
WitnessOS Simulation
Interactive Simulation
In-browser simulation: this page runs entirely in your browser with sample data. It illustrates the WitnessOS governed-action flow (policy evaluation, hash-chained events, signed receipts). No real action is executed here. The real record, made 5 Sep 2026, carries an RFC 3161 timestamp (revocation-verified at issuance) whose timestamp and Merkle inclusion proof independently re-verify offline from the export bundle: anchoring VERDICT PASS. The provider response behind that record is our own, so under the hardened ladder the receipt grades E2 Enforced. It was issued under an earlier evidence path and is shown here as E2, not E4. WitnessOS can produce independently verifiable E4 evidence for governed agent actions: E4 requires legitimate E3 corroborated evidence plus independently authenticated external anchoring, as introduced in WitnessOS Gateway v0.1.0 and witnessos-verifier v0.3.5.
