Interface ReplayOptions<S>

Apply at most this many events from the recording (clamped to [0, events.length]). Use to scrub to a specific point.

Called after each applied event with the resulting state.

When true, every intermediate state is deep-frozen — surfaces accidental action mutations as TypeErrors. Slower; use in tests, not production.

The recording's initialState is structured-cloned before freezing, so the caller's reference is never mutated.
