Period-Decided Disposition

Kind: principle

Layer: Execution Core

Record: architecture:period-decided-disposition

Severity: recommended

Scope: duplicate, derivation

Canonical: Ontology

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.

Listed in Architecture principles, after Declare-Before-Read Order and before Derived Party Count.
