"""Verifier layer: parse hypothesis, simulate, score, summarise mismatch.

Public API:

- :func:`parse_equation` (``parser``): convert a SymPy-grammar string into a
  callable ODE right-hand-side, validated against a strict whitelist.
- :func:`simulate_hypothesis` (``simulator``): run the parsed RHS forward in
  time via ``scipy.integrate.odeint``.
- :func:`compute_match` (``metrics``): R-squared between observed and
  predicted trajectories.
- :func:`summarize_mismatch` (``mismatch``): generate a one-sentence English
  description of where prediction diverges from observation.
- :func:`compute_reward` (``reward``): combine all components into a
  :class:`RewardBreakdown`.
