Optional reverse recurrence for a sliding-window reduction: the per-step downdate that removes the sample leaving the window, the inverse of equation (which folds an arriving sample in). Only meaningful when equation_type: recurrence on an observation’s auxiliary dynamics. When present, the observer is a windowed reduction — its state is maintained by equation (add) and evict_equation (evict) and rebuilt exactly from the window on resync — rather than a cumulative accumulator over the whole trajectory (equation alone). Absent for ordinary state variables and cumulative reductions.
