# Reproduction bundle

Deterministic CPU-only audit of all six exact registered claims for OpenReview
`QYA0Q28ssf`, pinned to immutable arXiv `2602.16601v1`.

```bash
PYTHONWARNINGS=error python3 reproduce.py --output replay --source-dir source
python3 build_manifest.py --verify
```

The bundle checks exact Gaussian KL/chi-squared identities, observability,
perturbative two-sided scaling, persistent and summable error recurrences,
geometric fresh-data memory, pinned source experiments, and a destructive
harmonic-error control that falsifies registered Claim 4 as literally worded.
