- **2026-06-01: power_off must pass an absolute `key_file_path`.** bscpylgtv's
`StorageSqliteDict` defaults the key DB to `os.getcwd()/.aiopylgtv.sqlite`
(its `$USER_HOME` fallback is not `$HOME`). The old pve173 setup worked only
because it SSHed in as seth, landing CWD in `/home/seth`. Under systemd
(cwd=/) it threw `sqlite3.OperationalError: unable to open database file`.
Fix: `WebOsClient.create(ip, key_file_path="~/.aiopylgtv.sqlite")`.
- **2026-06-01: power_off retries (2×, 10s apart).** A TV woken seconds earlier
answers TCP :3000 but refuses a WebSocket control session for ~20-30s, so an
immediate OFF-after-ON can fail. Retry covers it; normal case (TV already up)
succeeds first try in ~3s. Bounded under the bridge's 60s subprocess timeout.
