- Snapshot listener set before notifying so subscribers can subscribe/ unsubscribe during notification without breaking the pass - Per-callback try/catch so one throwing subscriber does not silence others - Object.freeze on each state object so the live reference returned by get() cannot be accidentally mutated externally (compile-time Readonly<> is hint only) - 3 new tests pinning these invariants
