The app reaches it through a root-owned socket, `/run/kiosk-wifi-helper.sock` (`kiosk-wifi-helper.socket`, group-restricted to the kiosk user, `0660`), rather than `sudo`: the app can end up running with Linux's "no new privileges" flag, and then sudo refuses with *"The no new privileges flag is set"*.

+- **Web UI now installs by default** during first-time provisioning (fixed port 8090, no prompt) instead of being opt-in — the Addons menu entry still works standalone for reconfiguring the port or reinstalling it on a kiosk provisioned before this change.
 - **The web UI can now install/reconfigure CUPS Printing, LMS Server, Squeezelite Player, and Asterisk Intercom, and check for updates** — the same four addons plus Update named directly. Every one of these is the exact same interactive `action_*` function the terminal menu already uses (no prompt/mutation refactor of any addon file), driven by piping the right answers on stdin — the same technique this project's own bash tests already use to drive these functions.
 - **Privilege model:** the web service itself still runs as `$KIOSK_USER` with zero ambient `sudo`. A new narrow, allow-listed root helper is the only way it ever gains privilege — reachable only via a single-path passwordless sudo rule (generated and validated with `visudo -c -f` before being installed), and it re-checks its own fixed action allow-list before dispatching anything. Chosen over running the whole service as root after asking directly: since this repo has no login of its own by design, a request that reaches the web UI with no reverse proxy in front is effectively unauthenticated, so the allow-list bounds what that can actually do to five vetted actions, never a root shell.
 - Long-running installs stream live output to the browser via Server-Sent Events, one action at a time — a second request while one is in flight gets a clear `409`, never silently queued or dropped.
@@ -1597,7 +1590,7 @@ full migration pass.
 **Previous (v2.16.0):**
 - **New: Web UI** (Addons → Web UI) — a small Node/Express app (`webui/`) giving a browser-based editor for Sites & Page Timing, Display & Interaction, and Password Protection & Lockout, the three Core Settings menus that are pure `config.json` read/write with no privileged system mutation involved. Runs as a systemd service under `$KIOSK_USER` (the same user Electron runs as), so it never needs `sudo` — it reads/writes `config.json` with normal filesystem permissions.
 - `webui/lib/config.js` re-implements `lib/config.sh`'s exact field list, defaults, and merge-on-save contract in JS — `kiosk-app/main.js` already reads the same `config.json` directly in JS, so this isn't a new pattern — meaning it can never silently clobber fields it doesn't track (Authelia's credentials, the unused quiet-hours fields, etc), the same failure mode previously fixed in `lib/config.sh`'s own history.
-- **Login follows the kiosk's password protection.** With password protection on (Core Settings → Password Protection & Lockout), the Web UI asks for the same PIN/password the lock screen uses (a session lasts 12 hours; 5 wrong tries in a row slow it down like the lock screen does; changing the code signs every browser out). With protection off there is no login, so beyond a trusted LAN turn protection on or put it behind a reverse proxy (e.g. Caddy) with Authelia forward-auth — Authelia integration is out of scope for this repo. Direct LAN access with protection off has no authentication at all — treat it like SSH access to the kiosk.
+- **No login of its own, by design.** Authelia runs elsewhere; the expectation is a reverse proxy (e.g. Caddy) with Authelia forward-auth in front of it, the same way other self-hosted apps get protected — Authelia integration is explicitly out of scope for this repo. Direct LAN access with no proxy in front has no authentication at all — treat it like SSH access to the kiosk.
 - Deliberately narrow scope for this first pass: WiFi, Timezone, Power/Display/Quiet Hours, Complete Uninstall, every other addon, and everything in Advanced remain terminal-only — a network-facing process shouldn't be handed `sudo`-level system mutation (netplan, `timedatectl`, `apt`, systemd timers) without a lot more thought than this pass gives it. A "restart kiosk display" action was left out for the same reason — would need a narrow polkit grant, a follow-up.
 - Wired into Complete Uninstall (`webui_do_uninstall`) and Clone Settings (addon-presence detection) the same way every other addon is.
 - This is the single-kiosk piece of the web-based GUI mentioned in this doc's "Modular Management" notes for a while — a central multi-kiosk fleet dashboard is an intentional follow-up, not part of this pass.

+### Same ports on every install
+
+New installs of this stack use the same three ports whether you install it from the kiosk add-on or from `ubuntu-post-install`:
+**8098** is the one to use (the Room for Books home page, with Koha behind the menu), 8099 is Add books direct, and 8097 is the
+public catalogue, which stays closed. If one is taken, the next free port is used and the installer prints it. Existing installs
+keep the ports they already have.
+
+## HTTPS with Caddy (and the live camera scanner)
+
+Phones only allow a live camera on an HTTPS page. One command adds Caddy in front of the library:
+
+```bash
+# a real domain that points at this machine (ports 80 and 443 reachable): the certificate is automatic
+sudo ./install.sh --domain library.example.com
+
+# a name only your own network knows (library.home.lan): Caddy makes its own certificate authority
+sudo ./install.sh --domain library.home.lan --lan-tls     # then install caddy-root.crt on your phones
+```
+
+It writes `Caddyfile`, starts a `caddy` container (the compose `caddy` profile), sets `STAFF_URL=https://<name>` and closes the plain-HTTP
+ports to the network (`BIND_ADDR=127.0.0.1`; add `--keep-direct` to leave them open). Then use `https://<name>/`: everything works
+as before, and the **Live scan** buttons appear on Add books and Lend / return. Behind your own Caddy instead, point it at the library
+port: `library.example.com { reverse_proxy <this machine>:8098 }` and set `STAFF_URL=https://library.example.com` in `.env`.
