Filesystem-native analytical tables you can actually read. Each table is plain Parquet plus JSON files you can open with everyday tools, with a fast SQL engine on top: row-level edits (delete, update, merge), near-instant repeat queries, full table history with time travel, and optional encryption. Built in Rust.

Claims mapped to offline tests.
