Mosaicagent

Agencies change an agent's model, framework and hosting while clients need continuity about what was evaluated, which policies applied and what failed. Mosaicagent creates a portable identity and signed evidence history across approved migrations, with client-readable dimensions rather than a naked trust badge. The supplied research confirms a live agent leaderboard, a free public transparency log and public attestation infrastructure, while finding no verified agency portal joining them. Funding, service levels and public infrastructure fees are observed market references, not fixed product pricing. A shared schema could gain adoption, but network effects are hypothetical and portability depends on governance. A cryptographic signature proves who signed a record and that it was not altered; it does not prove the underlying claim, agent identity continuity or future safety. Identity, software version, evaluation run, result, policy event, attestation, anchor receipt, client interpretation and procurement decision remain separate. Only hashes and non-sensitive metadata belong on a public ledger. The product can make evidence portable and tamper-evident within a stated threat model. It cannot create objective trust or guarantee behavior.
