 ## 2. How a task is judged finished
 
+*This is a rule for this project, not a rule of Paperclip's. Paperclip has no such field:
+an agent sets a task's status itself. This project chooses to add a command when a task must
+be hard to fake, and to leave it out when the agent's own tests are enough.*
+
 The test is a **command**, kept with the project, and agreed **before** the work starts.
 Whoever did the work does not decide. If the command fails, the task is not done, and the
 reason is kept and shown.
