get(key: string)

Current holder of key, or null. Reactive (reads entries).

@paramkeystring

register(key: string, value: T)

Registers value under key. Idempotent for the same (key, value) pair. Registering a DIFFERENT value under an existing key is swap-is-noop: the first registration stays live and dev mode warns - unregister the current holder first for a true swap.

@paramkeystring

@paramvalueT

unregister#void

unregister(key: string, value: T)

Removes the registration for key - but only while value is still the registered holder. A stale holder unregistering after a successor has claimed the key leaves the successor untouched.
