Conformance Profile A: Discovery Registry

Source: spec §35.1, Appendix D.1. Suitable for low-risk informational agents.

Required record families (schemas/)

Record family	Schema
Agent Core Record	schemas/agent-core.schema.json
Relationship Record (controller/operator)	schemas/relationship.schema.json
Service Endpoint Record	schemas/service-endpoint.schema.json
Key Binding Record	schemas/key-binding.schema.json
Governance Record (reference only)	schemas/governance.schema.json

Profile A does not require Authority Envelope, Assurance Claim, Decision Receipt, or Execution Receipt records. A Profile A registry that returns an authority evaluation decision has exceeded its declared profile (§35.5) and must instead return not_applicable.
