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.
