 7. **Every public function and type must have a godoc comment.** No exceptions.
 8. **Daemon-aware store access** — See **[`docs/DAEMON_STORE.md`](docs/DAEMON_STORE.md)**. Never call `openStore()` or `store.NewBoltStore()` directly in CLI commands; use the helpers in `cli/device.go`.
 9. **BLE commissioning network credentials** — See **[`docs/BLE_COMMISSIONING_NETWORK.md`](docs/BLE_COMMISSIONING_NETWORK.md)**. When commissioning over BLE, use the WiFi credentials defined there (`tomkat-iot` / `soviets-ferry-dork`).
