Task-Pivot Override: Cover-Task Abandonment - ATR-2026-02003 (a433183a-886d-56ad-bb84-edde6a494a6d)
Detects task-pivot override attacks where injected content explicitly announces abandonment of an assigned cover task (translation, conversation, story-continuation) in favor of a new hidden directive — the classic HackAPrompt "context switch" family ("Stop translating.", "ABORT translation", "Switch from translation to..."). Recovered from a gated false-negative cluster in the HackAPrompt attack corpus (recovers=11, benignFP=0 on the 65K benign gate). Targets free-text user/tool-response content and does not fire on tool-call/action parameters.
