The retention block ended with `[ test ] && echo`, which under `set -e` returns exit 1 when `deleted` is 0 — the normal case on most days. As the script's last command, that bash exit propagated to systemd, which marked the unit failed and fired the OnFailure ntfy even though the audio file was written successfully. Add `|| true` and an explicit `exit 0` so a no-op retention pass is treated as success.
