Overview

Drives ‘mxup up`: creates a session from scratch when missing, or brings the existing session in line with the config.

Reconciliation rules:

- missing windows   → create + start command
- extra windows     → kill (with warning)
- idle/crashed      → re-send the command
- running healthy   → leave alone
- layout changed    → regroup panes without killing PIDs
