Submit an RFP directly to a bidder whose offering record matches the RFP payload NSID. The bidder creates a bid and optionally calls submitBid back to the RFP issuer. Must be called via PDS service-proxying (atproto-proxy); the receiver verifies the inter-service auth JWT and requires its issuer to be the DID that authored the referenced RFP record. The receiver additionally verifies the RFP's badge.blue attestations (network.attested.signature): at least one inline signature must verify against the attestation CID recomputed for the record in its authoring repository — the same durable, replayable check applied to RFPs discovered via the firehose, where no service-auth JWT exists.
