The concept defines the mechanism of object identity as a distinct property from object equality, governed by the hash-consed storage addresses allocated during runtime instantiation. It utilizes the formal operation of hash-based address comparison to determine if two references denote the exact same memory location within a single-address-space memory model. This principle serves as a foundational rule in computer science regarding the lifecycle of mutable data structures and the semantics of reference semantics.
