5/// Post-processes forwarding actions from an inner strategy.

7/// Filters are applied in order by `ComposedStrategy`. Each filter can
8/// reorder, remove, or augment faces in `Forward` actions — for example,
9/// removing faces with RSSI below a threshold.
10///
11/// If a filter removes all faces from a `Forward` action, the composed
12/// strategy falls through to the next action in the list (typically `Nack`
13/// or `Suppress`).
