Relay owns traces
Relay creates the decision receipt, trace, replay, and review route
Registry only supplies the stable actor context behind the reviewed agent
Passport ref
A trace can carry a Passport ref for the agent involved
That ref identifies the agent, owner, capability, version, and standing
Role boundary
Registry does not inspect replay detail or private action payloads
It does not issue decisions, approve actions, or store Relay traffic
Public boundary
Public pages can show safe identity and standing context
Private traces, replay detail, and decision receipts stay in protected Relay surfaces
When it matters
Agent-to-agent review needs to know which actor a trace refers to
Registry keeps that actor reference stable without becoming the trace system
