  95inductive Uncertainty where
  96  /-- Symmetric 1σ uncertainty (standard deviation), in the same units as the value. -/
  97  | sigma (σ : ℝ) (hσ : 0 ≤ σ)
  98  /-- Interval uncertainty: the true value lies in `[lo, hi]`. -/
  99  | interval (lo hi : ℝ) (hlohi : lo ≤ hi)
 100  /-- Finite discrete distribution scaffold: list of `(value, weight)` pairs.
 101      We do not require proof obligations (nonneg/sum=1) in v2; protocols must state hygiene. -/
