content_hash(32B)+payload_kind -> (disk,file,slot,page_bytes,crc,last_access,hit_count,flags). Validated topology (research C + multi-proc re-bench): owner ranks write durably (serialized on LMDB's write mutex, ~11x headroom over spill demand), all ranks read exists_prefix lockless (~1-3us, coherent). writemap=False (multi-process-safe). last_access/hit_count carry the replicated logical clock so L3 eviction selection is rank-uniform (3.3 consumes it). write_batch commits an object's entries atomically + durably (data->fsync->index->fsync ordering); iter_entries + reopen drive cold-rebuild; clear() is the flush_cache hook. 7/7 unit tests (venv lmdb 2.2.1).
