Standard translation metrics and 235B-parameter LLM judges actively reward the worst social media translations due to cultural blindness, but progressively decaying masked cultural scaffolding enables an 8B model to rival Gemini-3.1-Pro.

Severity scores are meaningless without spatial grounding: gating RL rewards on strictly ordered localization and classification dependencies forces MLLMs to diagnose visual degradation rather than hallucinate holistic quality metrics.

Current translation metrics miss the mark on capturing the cultural nuances and emotional resonance crucial for effective social media UGC translation.
