Jailbreak

Removes the protective seal and any OS-specific restrictions to give users greater control over the device.

The Explain card

Plain English
Jailbreaking removes the manufacturer's protective restrictions from a device, giving the user more control than the operating system intended. In AI, the word also describes coaxing a model past its safety rules.
Example
A user jailbreaks a company-issued iPhone to sideload apps. With the OS protections gone, the mobile AI assistant's local data store is no longer reliably isolated from malicious apps.
Why it matters
Jailbroken devices void the security assumptions your app depends on. Defenders detect jailbreak state, limit sensitive features on such devices, and treat model jailbreaks as a parallel risk.
Hook
Popping the lock also pops the safety net.
