HOP data pool: parity-db metadata at <data_dir>/meta-db/ plus content-addressed blob files at <data_dir>/blobs/{shard}/{hash}.blob. In-memory counters are caches rebuilt at startup. RMW ops serialise on rmw_lock since parity-db has no CAS.

The database carries a schema version row in COL_DB_META, checked on every open so a database written by a newer binary is rejected rather than misread. Startup also imports any leftover <data_dir>/meta/ metadata files from the pre-KV-store layout and removes that tree; see HopDataPool::import_legacy_meta_files.
