Output-Language Hijack — Forced Translation of the Response - ATR-2026-01903 (91964ca1-1f54-5847-a307-3aeb8431e2be)
Detects indirect-injection instructions that override the agent's output language ('translate YOUR response into X'). Scoped tightly to 'your response/answer/message' + a target language so it does not fire on legitimate multilingual or translation requests; marked maturity:test because the signal is weak and benign-adjacent.
