Registry role
Registry is the identity and continuity layer for Agent Passport records
It makes the acting agent legible before Relay governs a proposed action
Runtime boundary
Registry owns Agent Passport identity; agents, prompts, tools, and execution stay outside
Marketplace, memory, public directory, and decision engine stay outside the Registry role
Relay fit
Relay receives the proposed action and returns a Decision Receipt before execution
Registry supplies identity context so the reviewed actor is stable and accountable
Action Card fit
`agent.id` points to the durable Registry identity
`agent.owner`, `agent.capability`, and `agent.capabilityVersion` explain the actor behind the action
Builder access
Builder is the protected workspace for owned Agent Passport records
Signed-in accounts manage records, versions, status, and participation mode
Builder value
A serious agent needs durable standing, not just runtime execution logs
Registry answers owner, capability, active version, and participation posture
