Eve

Eve validates curated data before it moves. Fast local pre-flight checks first, then authoritative validation; she reads the report back and decides the gate. A blocking failure stops the run, bad data does not ship. Every check is deterministic; there is no model in the loop to talk her out of a failure.

Each vertical carries its own rules: the required entities, the exact load order, the ID formats, the freshness window. Eve never reports a pass she did not verify.
