{"id":"deferred-duplication-principle-spans-temporal-and-spatial-domains","text":"The deferred-duplication principle (Memento's incremental deltas and copy-on-write Proxy's deferred copying) and the controlled-sharing meta-pattern (Singleton registries and Flyweight factories) represent two complementary efficiency strategies observable in the GoF catalog: deferring duplication until modification (applied independently in temporal and spatial domains) and sharing instances via creational infrastructure until differentiation is needed. Together, these strategies suggest a recurring concern with managing the costs associated with object proliferation, though the antecedents establish these as patterns within specific subsets of the catalog rather than as a unified architectural framework governing all GoF state management.","truth_value":"IN","source":"","source_url":"","source_hash":"","justifications":[{"type":"SL","antecedents":["memento-incremental-optimization-mirrors-cow-proxy","controlled-sharing-meta-pattern"],"outlist":[],"label":"Deferred duplication and controlled sharing are two faces of the same efficiency strategy combating composition's object proliferation"}],"dependents":["efficiency-meta-patterns-manage-composition-proliferation-costs"],"metadata":{"source_type":"derived","review_result":"pass","repair_action":"softened"},"created_at":"2026-06-18T02:19:13+00:00","updated_at":"2026-06-18T06:15:08+00:00","reviewed_at":"2026-06-18T06:15:08+00:00","verified_at":"","retracted_at":"","explanation":{"steps":[{"node":"deferred-duplication-principle-spans-temporal-and-spatial-domains","truth_value":"IN","reason":"SL justification valid","antecedents":["memento-incremental-optimization-mirrors-cow-proxy","controlled-sharing-meta-pattern"],"label":"Deferred duplication and controlled sharing are two faces of the same efficiency strategy combating composition's object proliferation"},{"node":"memento-incremental-optimization-mirrors-cow-proxy","truth_value":"IN","reason":"SL justification valid","antecedents":["memento-incremental-when-predictable-sequence","copy-on-write-proxy-optimization"],"label":"Memento incremental deltas and copy-on-write Proxy share the defer-duplication-until-necessary principle"},{"node":"memento-incremental-when-predictable-sequence","truth_value":"IN","reason":"premise"},{"node":"copy-on-write-proxy-optimization","truth_value":"IN","reason":"premise"},{"node":"controlled-sharing-meta-pattern","truth_value":"IN","reason":"SL justification valid","antecedents":["gof-state-subclasses-often-singletons","flyweight-factory-ensures-sharing"],"label":"Depth-1 — two independent base observations (State-as-Singleton and Flyweight-via-Factory) converge on a cross-category meta-pattern where creational mechanisms serve as sharing infrastructure for behavioral and structural patterns"},{"node":"gof-state-subclasses-often-singletons","truth_value":"IN","reason":"premise"},{"node":"flyweight-factory-ensures-sharing","truth_value":"IN","reason":"premise"}]}}
