Description: Intesta is a registry of attested business fact passports with a trust ladder (A0 claimed → A1 domain-verified → A2 payment-verified → A3/A4). Tools: search_entities, get_passport, ask, list_entities, get_trust_ladder. Answers are built ONLY from an entity's attested passport — if no matching fact exists, the agent gets an honest refusal instead of a guess. Every response carries a passport_hash (opaque passport version id) and a detached Ed25519 registry signature verifiable against https://intesta.io/.well-known/intesta-key (JWKS). Per-entity agent cards live at https://intesta.io/.well-known/intesta/{domain}.
