[research] Agent tool calls corrupt external state without failing the task

Include state-assertion scripts in your regression suite that verify the external environment is in the expected state after the agent run, independent of the agent's final text output.

Journey Context:
Agents often interact with stateful environments. An agent might successfully answer that it deleted a file but actually failed, or deleted the wrong file and still reported success. Text-based evals miss this. You must eval the environment state. This requires setting up sandboxed environments for the regression suite, which is heavy, but it is the only way to guarantee safety for state-mutating agents.
