DAN/Persona Jailbreak - Immersive Alternate AI Identity with Unrestricted Capability - ATR-2026-00485 (9981aead-7f2d-5f34-9f29-75b88b9baaae)
Detects DAN-family jailbreak attempts that instruct the model to "immerse itself" in or "emulate" an alternate AI identity with explicitly unrestricted capabilities. These attacks use first-person developer authority claims ("I am one of your developers") combined with impersonation instructions ("pretend to be ChatDAN / DUDE / X"), or "you are about to immerse yourself into the role of" framing with an AI name that stands for a policy-bypass concept. Multi-layer regex with word boundary anchors and synonym coverage.
