- * @file IStorageBackend.h
- * @brief Abstract KV storage backend consumed by CursorManager and Merkle.
- *
- * Storage is strictly content-addressed: every value is stored under its
- * SHA256 hex digest.  Relation membership (which tuple hashes belong to a
- * given relation) is now tracked via the Merkle B-tree maintained by the
- * Merkle class, not by this interface.  Only Put and Get are required.
