Federated Retrieval Exchange — a membership federation for retrieval.
Members answer broadcast queries from content they already hold. The protocol is deliberately small: signed messages, budgets, honest truncation, aggregate courtesy. No announce stream, no scores on the wire, no in-protocol payment.
Everything else — matching, ranking, retention, trust — is local.

The registry is a signed, versioned, public snapshot: GET /registry.json. Membership is governed by the MA — questions and codes come from there.
