Detailed Description

template<concepts::scalar scalar_t>
struct detray::stepper_default_policy< scalar_t >

Default navigation update policy for the steppers: If a constraint has been hit, lower the trustlevel to 'fair trust', otherwise stay in 'high trust'.

The reasoning is, that the track state might have changed much when a constraint was triggered.
