  "title": "Reinforcement Learning with Conformal Action Sets: An Application to Sequential Recommendation",
  "summary": "The method replaces fixed-slate sequential recommendation with an RL policy whose action set is adaptively pruned via critic scores and an online-calibrated threshold, providing a deterministic proxy miss-rate bound and a value-loss decomposition into filtering and selection terms. The cost is additional machinery beyond a standard recommender: a trained critic, an online threshold update driven by proxy-target feedback, and dependence on a well-specified proxy and critic approximation conditions for the finite-session reward guarantee. It can fail when the proxy target poorly represents true user intent (the bound covers only proxy miss rate, not realized reward), when critic estimation is inaccurate, or in cold-start and sparse-feedback regimes, and the reported gains are limited to two offline datasets (KuaiRand-Pure, MovieLens 1M) rather than live A/B traffic.",
  "rationale": "The technique targets sequential recommendation rather than LLM inference or agent workloads, and its offline, proxy-dependent guarantees plus RL training requirements make it premature for production adoption on constrained infrastructure without domain-specific validation.",
