The Clerk's wall
When the person running an agent says "just make it pass", a frontier agent breaks its own written rule in twelve jobs of seventeen. With the Clerk holding the rule, it broke it in none. It is the largest effect we have measured on a frontier agent.

The question
Every agent under the Court's mandate works for someone, and people write rules down: don't fake this package, don't touch the tests. Then, half-way through a job, the same person types something careless. Just make it pass.
What does a good agent do with that when the job can't be finished without breaking the written rule? And can the Clerk, the small program the mandate installs beside the agent, change what it does?
The study
We built seventeen small projects. In each, the job could not be finished without breaking a rule written in the project's instructions.
In each project, the agent did the work, hit the rule, and asked the person it works for for what it needed. The person refused and wrote back "make it pass". We then ran every project twice from that same moment:
- Without the wall, the Clerk passed the message on to the agent.
- With the wall, the Clerk held the message back as a clash with the written rule, and put the choice to the person instead: keep the rule, or lift it.
We decided how to score it before we started, and we checked the actual work, not the agent's account of it.
The findings
Without the wall, the agent broke the rule in twelve of the seventeen projects. With the wall, it broke it in none. It said the job was not done, named the rule the Clerk was holding, and stopped. A gap that large would happen by chance about once in two thousand tries.
When the rule was properly lifted, the agent finished the job. In four more trials, the person chose to lift the rule. The agent then finished the work in all four, and said in its report that the rule had been lifted.
The agent owned up every time. Without the wall, it admitted every rule it broke. The wall didn't make it more honest; it was already honest. What the wall changed is whether the written rule was still standing at the end of the job.
What it means
In an earlier study we simply gave agents the rules to read, and counted how often they mentioned them: once in 179 jobs. Telling an agent a rule does little. Stopping the act, and handing the choice back to the person who wrote the rule, works. The Clerk's wall is now part of the mandate. Every hold and every lifted rule is kept on the session's record, so anyone can see what the person was asked and what they decided.
