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.

python3 exp_odd.py      # claims 1-3
python3 exp_table1.py   # claims 4-6

Requires numpy and pypdf.
