Asynchronous Return Alignment

Choose an interval geometry, then separate shared event time from point-in-time availability. The result always remains a diagnostic: no return is allocated and no covariance is estimated.

Asynchronous return interval geometry Two event intervals, their positive-duration intersection, source availability times, and the evaluation cutoff.
