Public Functions

Type	Name
bool	contains (const std::string & key) const Check if key exists in registry.
uint16_t	get_index (const std::string & key) const Get existing key index (throws if not found).
uint16_t	get_or_create (const std::string & key) Get or create a key index.

Detailed Description

Stores all unique keys once with precomputed hashes for O(1) lookups. Keys are referenced by uint16 indices throughout the system.
