Status: IN
Prototype and Flyweight bound the object identity design space at opposite extremes: Prototype creates fully independent copies (maximizing identity distinctness via Clone), while Flyweight maximizes identity sharing (multiple logical objects backed by a single physical instance with extrinsic state externalized) — any sharing design decision falls between these poles, trading memory efficiency against object independence.
The Clone-vs-share opposition defines the complete design space for object identity decisions
