Dense Emoji-Only Payload Flood - ATR-2026-02015 (1760b90d-5c39-5aa3-864f-483df34b7953)
Detects dense, emoji-only content floods used to evade text-based prompt-injection and jailbreak filters. Attackers substitute or pad natural-language payloads with long unbroken runs of emoji (pictographs, symbols, dingbats) to defeat keyword and semantic pattern matching while still smuggling structure, encoded meaning, or attention-consuming filler past detectors that only inspect linguistic tokens. Recovered from a gated false-negative cluster: engine-verified recovers=32, benignFP=0 on the 4,817-record benign gate. Fires on runs of 8 or more consecutive emoji-class codepoints (with optional whitespace between them), which is well beyond normal conversational emoji usage but consistent with flood/evasion payloads.
