A prominent $π^{0}π^{0}$ mass threshold enhancement, mirroring the $π^+π^-$ channel, is definitively observed in $ψ(3686)$ decays, challenging simple chiral descriptions.

$U$-spin symmetry is substantially broken in $D^0 \to K\pi\pi$ decays, with measured breaking parameters reaching magnitudes up to $4.45$.

Altermagnetic symmetry breaks the optical silence of spin-forbidden dark excitons, generating symmetric exciton-magnon sidebands that directly track underlying spin correlations.

DSR is introduced, a causal post-selection operator that repairs destination support without retraining the host predictor or increasing the maintained set size, and shows that finite-set support allocation is a useful prediction-side control point when a fixed hypothesis set serves as the interface to downstream systems.
