Status: IN
Builder's empty-by-default build methods, Template Method's hook operations (default to no-op, may be overridden), and Strategy's optional null-with-fallback all instantiate a common selective-override meta-pattern: provide safe default behavior (typically doing nothing) so that clients or subclasses engage only with the operations they need, enabling incremental adoption rather than all-or-nothing commitment.
Three independently documented no-op/default mechanisms across Creational, Behavioral-inheritance, and Behavioral-composition categories converge on a single cross-category selective-override meta-pattern
