{"id":"decorator-identity-and-order-constrain-wrapping-taxonomy","text":"Decorator's operational constraints (identity breakage and composition order sensitivity) are consequences of transparent recursive delegation via single-child wrapping. Since Decorator is structurally identical to degenerate Composite, these constraints likely apply to any mechanism sharing that same single-child wrapping structure. This suggests that the wrapping taxonomy (Proxy→Decorator→Strategy), which operates on this structural foundation, may be bounded not only by encapsulation concerns but also by the fragility inherent in transparent recursive delegation — though the extent to which these constraints limit other points on the taxonomy requires further examination.","truth_value":"IN","source":"","source_url":"","source_hash":"","justifications":[{"type":"SL","antecedents":["decorator-operational-constraints","decorator-composite-structural-unity-grounds-wrapping-taxonomy"],"outlist":[],"label":"Decorator's
