QATQ v0.1.0-rc1
Pre-release
Pre-release
QATQ v0.1.0-rc1 is a source release candidate for review from the tagged repository state. It is not a crates.io publish, and no crate, binary, or container artifacts are being published yet.
Highlights:
- Phase 2 exact/lossless path: byte-plane block/RLE candidates, adjacent-bit delta-XOR byte-plane RLE probing, raw-bits fallback, and the QATC large-tensor container path.
- Public fixtures: deterministic generated fixture corpus in
fixtures/generatedwithfixtures/public.manifest; four fixtures, 40,960 values, and 163,840 bytes covered bydocs/PUBLIC_FIXTURE_AUDIT.md. - CI and fuzz scaffold: GitHub Actions CI plus cargo-fuzz targets for decode payload handling and Phase 2 round-trip coverage.
- Baselines: public comparative codec tables for raw f32, zstd, lz4, fp8-e4m3, lossy-i4, turboquant-q4, phase1-q4, and Phase 2 lossless modes.
- Quality-proxy report: deterministic codec-level inner-product probes in
docs/PUBLIC_QUALITY_EXPERIMENTS.md; this is not a model-quality or perplexity claim.
Release-review scope:
- Install/build from tag only.
- Run
docs/RELEASE_CHECKLIST.mdfrom a clean clone. - Confirm docs, examples, fixture generation, package contents, and CLI commands work from the tagged state.
Known final-v0.1.0 blockers:
- Keep crates.io publishing deferred until public API names are stable.
- Add longer or scheduled fuzzing.
- Add at least one end-to-end model/task quality experiment before making stronger QATQ-vs-TurboQuant quality claims.
- Keep lossless claims limited to Phase 2.
