# 6-remove-agent-stacks.sh — remove ALL boot-time screen/crush stack relaunchers.
# Target state: no screen/crush sessions auto-start on reboot, any account.
#   - reachableceo-agent-stack.service (boot respawn RCEO-PMO/RCEO-Work + prompt injection)
#   - tsg-supervisor.timer/.service (5-min self-heal respawning TSG PMO/Work screens)
#   - tsg-agent-stacks.service (dead unit: ExecStart script already missing)
#   - launcher scripts moved to backup so nothing re-triggers them by accident
# Everything is backed up to removed-agent-stacks/ in this repo; rollback =
# restore files + systemctl enable. Also quits the leftover ROOT screen
# 'ukrrs-gateway-final' (perf-pass leftover). Does NOT touch screen 'boot'
# (may host the live crush session; it dies at the multiqueue bounce anyway).
# Self-elevating. Run from the guest:  ~/projects/ultix/6-remove-agent-stacks.sh
