Template Method's fine-grained override control (five operation kinds, non-virtual skeleton, hook vs. abstract distinction) constitutes the principled counterexample to composition's general superiority: it demonstrates that inheritance-based reuse can be made disciplined under specific structural constraints — a controlled inversion channel within the otherwise composition-dominant paradigm.
Template Method is the exception that proves the composition rule by showing when inheritance works
