Content-fingerprint grouping via FNV-1a hash of file headers: files sharing identical first 4096 bytes are assigned a custom master block built from the largest file in the group. Masters are compressed with SuperMaster and written as MASMETA records in the central directory. Files below 1 KB or without a group continue using the SuperMaster. Includes CLI integration test and documentation updates (format spec, usage, roadmap).

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
|
|
producing bitstreams compatible with the original format.
|
|
|
|
3. **Modernized Master-Block Deduplication** — In progress.
|
|
Content-fingerprint grouping and custom master-block generation done
|
|
(FNV-1a sampling, MASMETA cdir records, SuperMaster-compressed
|
|
masters). Remaining: content-defined chunking, Merkle DAG,
|
|
cross-archive dedup, near-duplicate detection.
|
|
|
|
4. **Modern Compression Backends** — ANS entropy coding,
|
|
zstd-inspired dictionary compression, content-aware preprocessing.
|
|
|
|
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,
|
|
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.
