Roadmap
=======

The development roadmap is maintained in ``ROADMAP.md`` at the project
root.  Key phases:

1. **Decompression MVP**  --  Done. Portable decompressor, CLI tool,
   CMake build system.

2. **Original Compression Engine**  --  Done. LZ77+Huffman compressor
   with custom Huffman trees, full backward compatibility, and UC2
   personality (``-q`` for scripting).  Automated DOSBox-X round-trip
   validates 4+5 files in both directions.

3. **Modernized Master-Block Deduplication**  --  Done.
   CDC with Gear hash, Merkle DAG with content addressing,
   cross-archive block store, SimHash near-duplicate detection,
   and delta compression.  All Phase 3 items complete.

4. **Modern Compression Backends**  --  Done.  rANS entropy coder (method
   10), zstd-style dictionary metadata, content-aware preprocessing
   (BCJ, BWT, delta), LZ4 ultra-fast, benchmark mode (``uc2 -B``).

5. **Quantum-Resistant Encryption**  --  CRYSTALS-Kyber + AES-256-GCM.

6. **DOS / FreeDOS / Retro-Computing**  --  DJGPP toolchain, vintage
   hardware support, self-extracting archives.

7. **Cryptographic Integrity & Timestamping**  --  BLAKE3 hashing done
   (pure C, 256-bit digests).  Remaining: integration into archive
   blocks, OpenTimestamps.

8. **Decentralized & Cloud Integration**  --  IPFS pinning,
   content-addressable dedup, cloud archiving.

9. **Zero-Knowledge Proofs**  --  Privacy-preserving archive verification.

10. **Ecosystem Integrations**  --  libarchive plugin, streaming dedup
    ingestion, file manager plugins.
