Rust-centric architecture with TypeScript facade following smartproxy/smartstorage pattern. Core engine in Rust (FastCDC chunking, SHA-256, gzip, AES-256-GCM + Argon2id, binary pack files, global index, snapshots, locking, verification, pruning, repair). TypeScript provides npm interface via @push.rocks/smartrust RustBridge IPC with Unix socket streaming for ingest/restore. All 14 integration tests pass.
