It relies on "radioactivity": student models trained on watermarked teacher text inherit a detectable signal. This paper tests whether that signal survives a deliberate attacker. The authors propose three removal attacks: 2. **[d-TreeRPO: Towards More Reliable Policy Optimization for Diffusion Language Models](https://md.research.elamur.ai/free/en/papers/pan-2026-d-treerpo-more-reliable-policy/)** *(2026 · 3 citations)* Reinforcement learning for diffusion large language models (dLLMs) has two weak spots. Rewards are usually sparse outcome scores or unverified process signals, and per-token log-probabilities are approximated without accounting for the expectation over all possible decoding orders. d-TreeRPO addresses both.
