When narrative content drives a physical actuator, three interrupt paths look like "just restore state" until they are not: an incoming Messages / iMessage / RCS / SMS conversation or in-line reply composer mid-session, a Wireless Emergency Alert / Presidential / AMBER / earthquake / severe-weather government alert, and a headphone-safety / loud-sound-reduction / system volume-limit sheet. Each needs a default that fails closed — toward idle, toward re-arm only after a named beat, toward interrupt-clear ≠ motor authority.
on incoming_messages_thread_or_reply_composer_opened(): ramp_to(IDLE, at=next_beat_boundary) armed = false on thread_dismissed_or_reply_sent(): # messaging UI gone ≠ motor envelope restored await user_resume(); await next_named_beat(); arm() on wireless_emergency_alert_or_government_alert_opened(): ramp_to(IDLE, at=next_beat_boundary) armed = false on alert_dismissed_or_acknowledged(): # alert UI cleared ≠ motor authority await user_resume(); await next_named_beat(); arm() on headphone_safety_or_volume_limit_sheet_opened(): ramp_to(IDLE, at=next_beat_boundary) armed = false on warning_dismissed_or_volume_lowered(): # safety UI gone ≠ previous intensity restored await user_resume(); await next_named_beat(); arm() The incoming-Messages rule is easy to mix up with an incoming voice or video call, a tap-to-open push, a co-player progress notification, Notification Center, and a Contacts or Calendar picker. A call is a telephony interrupt. A push-open brings an app forward. A progress notification is not a conversation surface. Notification Center is a shade of history. A picker is a people-or-event sheet. A Messages thread is a conversation surface. Dismissing it or sending a reply clears that surface; it must not restore motor authority.
The Wireless Emergency Alert rule sits next to — but is not — a user-scheduled alarm or calendar notice, a tap-to-open push, Notification Center, Focus / Do Not Disturb, or a Live Activity / Dynamic Island. An alarm is user-scheduled. A push is opt-in app mail. Notification Center is a history shade. Focus can silence ordinary alerts; WEA can pierce it. Live Activity is a phone-side glance. A WEA is a government or carrier emergency alert. Acknowledge only clears that alert; it must not restore motor authority.
The headphone-safety rule is an OS hearing-safety dialog, not a Bluetooth audio-route change, not muting story audio, not a voice-assistant takeover, and not VoiceOver or a magnifier. Audio-route change is an already-paired headset connecting, disconnecting, or flipping to speaker. Mute is a playback control. A voice assistant takes over the session. VoiceOver is an accessibility surface. A volume-limit sheet is a safety warning. Dismissing it or turning the volume down only clears that warning; it must not restore motor authority.
Buyers can test two of the three without code: open a Messages thread or in-line reply mid-session and see whether dismissing it or sending a reply restarts intensity, and trigger a headphone safety or volume-limit warning then dismiss it. A Wireless Emergency Alert is harder to stage, but the acceptance question is the same: acknowledging the alert must not put motor authority back on. These map to questions like "how do AI stories control physical devices" and "Lovense alternative with AI stories."
