Recommended action: Register the transport the agent offers (WithGRPCTransport/REST) and, for 0.3 agents, the a2acompat/a2av0 transports; ensure the card lists supportedInterfaces. Option: Register matching transports [evidence: official_recommended_action] Applies when: See trigger Steps: 1. Inspect the listed binding_version pairs 2. Add the matching transport (and v0 compat for 0.3) to the factory config Expected: Error no longer occurs Evidence basis (self-declared by the contributing chat client): untested.
