Conditioned PSD sensing bottleneck

Represent an intermediate feature as a low-rank PSD matrix and compress it using nonnegative measurements \(\langle A_i,X\rangle\), while penalizing the empirical ratio between maximum and minimum measurement distortion over low-rank feature pairs. This directly discourages collapsed directions and excessively amplified directions in a covariance or Gram-feature bottleneck.

Finite-horizon Lyapunov regularization for neural updates

Add a loss term requiring a neural optimizer or recurrent module to decrease a nonnegative Lyapunov-like energy over M update steps, rather than forcing monotonic one-step decrease. The term includes an empirically estimated mismatch allowance, so stochastic or delayed updates are tolerated while persistent instability remains penalized.
