**Holds when.**

- Persona Protocol v0.3 as proposed; not an adopted standard

**Protocol.** TrustCarry Protocol v0.3, historically titled and aliased as Persona Protocol v0.3.

**Supporting passage from Persona Protocol v0.3.**

> None of these integrations changes the meaning of a protocol object. An MCP tool listing is not evidence of competence. An A2A Agent Card is a discovery and presentation document, even when signed. An attestation establishes only what its evidence and its appraisal policy support. A credential remains an issuer claim. An authority token remains bounded by its issuer and its scope.
