  15/-- **DEFINITION: PMNS Unitarity Forcing**
  16    A matrix `U` satisfies `PMNSUnitarity U` if it is unitary and its Born-rule
  17    probabilities `‖U i j‖^2` match the framework’s predicted weight tensor.
  18
  19    Note: existence of such a `U` is currently treated as a quarantined conjecture
  20    (`IndisputableMonolith/Physics/PMNS/Construction.lean`). The certified particle
  21    claims do **not** depend on that existence statement. -/
