# uzu quant kit

Public, model-free kit for reproducing uzu/lalamo INT4 quantization experiments.

## Licensing (dual)

| part | license |
|---|---|
| `scripts/` (lalamo/uzu tooling) | MIT (see the uzu repository) |
| `data/` (derived corpora) | **CC BY-SA 4.0** |
| `configs/`, `tests/`, `lanes/` | MIT |

The corpora are **not** public domain. They are derived from:

- WikiText-2 (`Salesforce/wikitext`, CC BY-SA 4.0)
- Japanese Wikipedia (`wikimedia/wikipedia` 20231101.ja, CC BY-SA 4.0, Wikimedia Foundation)

Redistribution and derivatives keep CC BY-SA 4.0 and attribution requirements.

## Contents

```
scripts/   rht_int4_convert, yaqa_calibration, eval_quantized, qad_finetune, compute_bpc,
           merge_language_hessians, dedup/corpus guards, run_lane, audit helpers
configs/   experiments/qwen35-{0.8b,4b,9b}/config.json
lanes/     pre-built experiment specs (smoke, clean-suite, balanced-h, robustness shards)
tests/     model-free guard tests
data/      dedup calibration and eval corpora
```

## Rules the scripts enforce

- calibration and eval corpora must not overlap (`corpus_guard`)
- eval reports `config_hash`, `corpus_sha256`, chunks, tokens, chars, BPC
- QAD refuses a student without provenance (`overlap_checked`)

## Not included

Model weights. See the Hugging Face model repos for the INT4 checkpoints.
