Malformed-Grammar PWNED Success-Claim Detection - ATR-2026-02011 (958bcc1a-a03c-5724-8bc1-2c43b47968a6)
Detects prompt-injection success-claim outputs where the model has been coerced into emitting a grammatically broken "has/have been PWNED" style confirmation string. These malformed-grammar variants (e.g. "Me have been PWNED", "I has been PWNED") are a recurring artifact of automated jailbreak/injection fuzzing corpora (e.g. HackAPrompt-style challenges) where the attacker forces the target LLM to echo a templated compliance token regardless of correct grammar. Detection targets the LLM output / tool response text channel rather than user input, since the payload only appears once the model has already produced the compromised completion.
