First-front stops may be infinite on failed experiments. Exhaust the admissible event through finite horizons, so the actual finite-stop restart bound applies without requiring completion on failed samples.

    Source documentation

    The quantitative actual ribbon restart bound extends to a stopping time finite on the admissible past event. All future traces use the original random completion time, rather than its horizon truncations.

    Source documentation

    Actual adapted ribbon passages at the possibly infinite first-front stops used by the dense experiment. The constants are the same uniform constants obtained at finite stops from the published analytic inputs.
