  recovered and lower R² throughout — it optimises tree-model lift, not
  equations.
- Heavy-tailed noise (Student t(2), infinite variance): exact formula
  recovered at R² 0.956 vs LightGBM 0.866 — the permutation test is
  distribution-free, so heavy tails cost it nothing.
- Known boundaries, measured: on piecewise targets trees win outright
  (LightGBM 0.998 vs 0.808 — if a tree model beats beamfeat by a wide
  margin, the signal is likely piecewise, not algebraic; OpenFE records 0.998
  there too, but bit-identically to raw LightGBM and from a feature touching
