RawRingApi
@RequiresOptIn(level = RequiresOptIn.Level.ERROR, message = "Raw ring API: the sink owns this C pointer and releases it on close. Opt in only at the native audio handoff boundary.")
Marks the native ring handoff that exposes the real-time core's raw C pointer.
Opting in means the caller accepts that the sink owns the pointer, that it stays valid only until the sink closes, and that no Kotlin code may free it.
