+### Fixed
+- Fixed missing `STARTING` and `LIVE` desktop notifications by adding `--property=KillMode=process` to the udev `systemd-run` rule. Prevents systemd control-group teardown from terminating the detached `fiero-prompt watch` process when the prompt script exits.

-The udev rule fires on any `power_supply` `change` event where `ATTR{type}=="Mains"` and `ATTR{online}` is `1` (plugged) or `0` (unplugged). This invokes `fiero-prompt.sh` as the logged-in user via `systemd-run` + `su` (so udev does not kill the long-running prompt), which presents a desktop notification action prompt and issues `sudo -n systemctl start|stop` accordingly. The first prompt run also spawns a detached, flock-serialized event watcher (`fiero-prompt watch`) that stays alive for the session.
+The udev rule fires on any `power_supply` `change` event where `ATTR{type}=="Mains"` and `ATTR{online}` is `1` (plugged) or `0` (unplugged). This invokes `fiero-prompt.sh` as the logged-in user via `systemd-run` + `su` (so udev does not kill the long-running prompt), which presents a desktop notification action prompt and issues `sudo -n systemctl start|stop` accordingly. The first prompt run also spawns a detached, flock-serialized event watcher (`fiero-prompt watch`) that stays alive for the session. That watcher is a child of the transient unit, and `setsid` severs the session but **not** the cgroup, so the rule pins `KillMode=process`: the default `control-group` would SIGTERM the whole cgroup — watcher included — the moment `su` exits, silently dropping every `STARTING`/`LIVE` notification. The transient unit then lingers `inactive` for as long as the watcher runs.
