- [Period-Decided Disposition](https://banes-lab.com/records/architecture/period-decided-disposition.md): A design rule that a duplicate is first counted by its distinguished copies and then read by the period of each derivation edge, so a periodic copy owes a comparator and a one-shot copy is a record whose source is repaired instead.
