# Reproduction bundle

Reproduction of **"An Odd Estimator for Shapley Values"** (arXiv:2602.01399v1,
OpenReview `xILwgiWAUk`).

Claims 1-3 are exact algebraic identities (Observation 3.1, Theorem 3.2,
Theorem 3.5). They are settled by exhaustive enumeration of all 2^d coalitions
and by solving the constrained Fourier regression through its exact KKT system —
no sampling, no estimator — and each is paired with a negative control that must
fail.

Claims 4-6 are assertions about Table 1 / Figure 2. They are audited against the
published table, transcribed from a SHA-256-pinned PDF.

```bash
python3 exp_odd.py      # claims 1-3
python3 exp_table1.py   # claims 4-6
python3 build_pages.py  # regenerate pages/
```

Requires numpy and pypdf.
