doing RL *literally* in production doesn’t really work outside of narrow settings like RLHF but the right way to do continual RL *is* exactly this semi-synthetic task loop, which you can do on-the-fly by mining tasks from traces + evolving high-fidelity sims from observations

When we first started Harbor-Index a few months ago, we thought: how hard could it be? 1,311 tasks passed our difficulty filter. What's left is just sampling a few hard tasks across benchmarks right? ...until an LLM audit flagged 1,004 of them as broken. For the next few
