How would audit records be chained, batched and anchored to the ledger?
Designed, not yet built
Short answer
Audit records must be hash-chained per node, batched into Merkle trees and the batch root anchored to the ledger at an interval (still an open decision). That is REQ-4502, a top-priority requirement for all three tiers. Not yet. It is designed in the specification and not built in the pilot. Test in the specification: deleting a local record breaks verification. Parts of it are explicitly marked as open in the specification.
This is designed, not built.
