  • Added fresh complex-pole solving for every trial.
  • Added complete VJP recomputation after every accepted geometry.
  • Added local branch, physical-template, passivity, reciprocity, residual, geometry, Q-improvement, Armijo, and plausible-gain gates.
  • Added resonance-stationary projected gradient optimization as the default.
  • Added optional safeguarded inverse BFGS with warm-up, curvature gates, and fail-safe resets.
  • Added atomic restart state and complete evaluation history.
  • Added matched incumbent/candidate FDTD checkpointing every two accepted steps by default.
