[research] Agent memory or context modifications cause regressions in previously working task sequences

Snapshot the agent's state \(memory, context window\) at critical decision points in your regression suite. Re-run evals from these snapshots to isolate whether failures are due to new logic or corrupted memory state.

Journey Context:
When an agent fails a regression test, it is hard to know if the prompt change broke the logic, or if a prior step injected bad context that poisoned the failing step. By checkpointing and replaying from state snapshots, you can deterministically isolate the point of failure. This is crucial for agents that accumulate state over long sessions.
