### FEAT-11 — Hotspot SSID/password settings + 5GHz WiFi role swap
- **Status**: `SHIPPED` 2026-08-12
- **Area**: `app.py`, `templates/settings.html`, `static/js/settings.js`,
`deploy/yaris-hotspot.sudoers`, `deploy/yaris_uplink.py`, `deploy/install_netwatch.sh`,
`modules/app_network.py`
- **Phase**: Phase 27
- **What**: Two related changes:
1. **Hotspot settings UI** — the Pi Settings page "In-car access" card now has SSID +
password fields (password write-only). `GET /api/hotspot` reads the current SSID via
nmcli; `POST /api/hotspot` updates SSID/password and restarts the AP immediately.
Backed by `deploy/yaris-hotspot.sudoers` (privileged nmcli on the `Hotspot-local`
profile).
2. **WiFi role swap** — the fast TP-Link T3U (wlan1) now hosts the in-car AP on **5GHz**
("vroom vroom yaris de course" at 10.42.0.1) for fast phone access (Android dev, video
browsing); the weak onboard BCM43438 (wlan0) carries the internet uplink (home WiFi
"BuzzBis" + phone hotspot, static IP 192.168.50.220). This was done because the AP on
the onboard radio was too slow for interactive Android work. Tradeoff: away-from-home
uploads now run over the weak radio (accepted — background task). A single radio cannot
be AP + client at once, so the phone-hotspot uplink must stay on wlan0.
- **Files**: `yaris_uplink.py` (PRIMARY=wlan0, AP_INTERFACE=wlan1, AP_CONNECTION=Hotspot-local),
`app_network.py` (uplink on wlan0, AP on wlan1), `install_netwatch.sh` (rebinds profiles).
