EthanfelandClaude Sonnet 4.6 445da1e69b fix: replace std clamp with anchor regularization to prevent OOD noise ...

The std clamp was post-hoc and only addressed magnitude, not direction.
x0 was drifting to mean=-0.55/std=3.1 (ODE expected mean=0/std=1).

Replace with anchor_weight * MSE(x0, x0_init) added directly to the loss.
The optimizer now balances style matching against staying near the initial
N(0,1) noise — gradient-aware, prevents both magnitude and mean drift.

Also logs style/anchor losses and x0_std per step for diagnostics.
