Status: IN
The noop-default meta-pattern (Builder empty methods, Template Method hooks, Strategy optional fallback) and the null-object meta-pattern (NullIterator always-done, null Strategy fallback) independently enable incremental pattern adoption through degenerate objects with safe default behavior — together constituting a pervasive compositional infrastructure layer that makes composition uniformly applicable without all-or-nothing commitment across Creational, Behavioral-inheritance, and Behavioral-composition categories.
Two independently discovered meta-patterns converge on incremental adoptability as cross-category compositional infrastructure
