Mickai-only chain
OAR chain files are produced exclusively by the Mickai SIOS when it logs agent actions. Files from other sources will fail the ML-DSA-65 signature check, which is the point: the verifier proves Mickai's chain integrity, not arbitrary signature verification. To obtain a sample OAR chain, install Mickai and run any agent action.
No sample to hand? Download a Mickai-signed sample chain and drop it into the verifier below.
