# ============================================================
# Asymmetric Lyapunov Regularization Experiment
# ============================================================
# Hypothesis: Using asymmetric penalty will balance between
# preventing chaos and allowing learning.
#
# Asymmetric loss:
# - Strong penalty for chaos (lambda > 0): relu(lambda)^2
# - Weak penalty for collapse (lambda < -1): 0.1 * relu(-lambda-1)^2
#
# This allows dynamics in the "sweet spot" of slightly negative
# Lyapunov exponents (stable but not dead).
