When narrative content drives a physical actuator, three interrupt paths look like "just restore state" until they are not: an Emergency SOS / Crash Detection / Medical ID emergency-call or Emergency SOS via satellite mid-session, a Find My Play Sound / remote lock / Lost Mode, and a liquid-detected USB-C or Lightning port / "This Accessory May Not Be Supported" / uncertified charger or data accessory sheet. Each needs a default that fails closed — toward idle, toward re-arm only after a named beat, toward interrupt-clear ≠ motor authority.

A call is regular telephony. A WEA is a carrier or government broadcast. An alarm is user-scheduled. A push-open brings an app forward. Emergency SOS is the phone's own emergency-calling flow, including crash detection, Medical ID emergency call, and SOS via satellite. Canceling or ending that flow clears that surface; it must not restore motor authority.
The Find My rule sits next to — but is not — a local user locking the screen, an in-app or device biometric re-auth, Guided Access or a Screen Time limit, a force-quit, or a user-scheduled alarm. A local lock is a user action on this device. Biometric re-auth is an identity challenge. Guided Access and Screen Time are restriction surfaces. Force-quit ends the process. A Find My Play Sound, remote lock, or Lost Mode is a remote locate or lock action. Dismissing the sound or unlocking only clears that action; it must not restore motor authority.
The liquid-detected / uncertified-accessory rule is an OS accessory-safety dialog, not a charging-started or charging-stopped play policy, not USB tethering or a personal hotspot, not a thermal step-down, not a Bluetooth pairing request, and not a hardware stop button. Charging-gate is a play policy around power state. Tethering is a network path. Thermal trip is a temperature step-down. Pairing is a Bluetooth consent sheet. A hardware stop is a physical control. A liquid-detected or uncertified-accessory sheet is a safety warning. Dismissing it or unplugging only clears that warning; it must not restore motor authority.
Buyers can test two of the three without code: trigger a Find My play-sound or remote lock mid-session and see whether dismissing it or unlocking restarts intensity, and trigger a liquid-detected or uncertified-accessory warning then dismiss it. Emergency SOS is harder to stage safely, but the acceptance question is the same: canceling the countdown or ending the emergency call 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."
