The directory of presence providers a policy may name

Third parties that prove a person was present for an intent, such as a card issuer's partner proving the cardholder tapped their own card (method CARD_TAP). Decionis operates the directory; each entry names the provider's attestation iss and the JWKS it publishes its Ed25519 keys at. An organisation trusts a provider only once it admits it (PUT /v1/execution/presence-providers/{provider_id}/admission). Requires policy:read, policy:write or org:* scope.
