## Built-in self-test coverage

The self-test generates:

- repeated text;
- tiny JSON files;
- exact rank-1 2D byte field;
- exact finite-difference polynomial word stream;
- random MP4-like bytes;
- sparse modified near-duplicate random MP4-like bytes;
- plain archive;
- encrypted archive;
- recovery-tail archive with one corrupted shard.

It then verifies exact extraction by byte-comparing input and output trees.

## Known limits

- Pure Python is not expected to beat native C/Rust compressors in speed.
- Recovery repairs replacement corruption in up to two detected shards; it does not repair arbitrary insertion/deletion damage.
- Password mode uses standard primitives implemented in auditable Python, but it has not undergone independent cryptographic audit.
- Windows ACLs, alternate data streams, and macOS resource forks are not fully preserved by the current portable metadata layer.
