Summary
create_segment accepts any criteria_hash: String including an empty string. The criteria_hash field is documented as an IPFS hash of the targeting criteria. An empty hash means the segment has no resolvable definition — any consumer (targeting engine, privacy layer) that fetches the criteria from IPFS will get nothing. The segment can still have members added to it, creating a segment whose membership rules are unknown.
