+`filter_for1(Aa01)` is a no-op for the first two families (Aa01 is intermediate),

+right-output membership wherever it occurs. All `filter_for2` calls are no-ops
+except the final `(Aa01, Ab01)` stage of `a01b2_a2b01`, which checks that output
+pair. In that family's second stage, the former inner
+`filter_for2(Aa01, Ab01)` check is absorbed into
+**`filter_for32(Aa01, Aa2, Ab01)`**; `Aa2` remains an unrestricted summation atom.
+
+For two cell-bearing output atoms the relative cell is `(Rb - Ra) % period`;
+with `Aa01` at the origin it is `Rb % period`. An empty sector retains the existing
+unrestricted behavior. The numerical regression also disables symmetry after each
+filtered run to verify replacement of the previous backend's filter.
