Notes and record state

Record note
Classified as hybrid because current first-party documentation describes off-chain order matching with on-chain settlement and self-custodial controls. HEI models Antarctic, Antarctic Exchange, AX, AMLP, AHLP, supported-chain deposit surfaces, and professional trading modes as one exchange entity.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
