-The root part is `/usr/local/bin/kiosk-wifi-helper` (status/scan/connect and region only). 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.

+
+## Signing in once
+
+Staff who are signed in to the library site (and allowed to edit the catalogue) open **Add books** without a second login. Koha itself confirms the sign-in; the shared secret is `SSO_SECRET` in `.env`. The read-only `guest` login still uses the Add books prompt, and the direct Add books port never accepts a Koha sign-in. If `SSO_SECRET` is empty, Add books just asks for its own login as before.
+
+## The home page (the Room for Books site at `/add/`)
+
+**One address.** `http://<ip>:<port>/` (and later `https://your-domain/` behind Caddy) opens this page; there is no separate
+port to remember. Koha's own staff screens live on the same address at `/cgi-bin/koha/mainpage.pl`, reached from the menu
+(*Koha (full staff screens)*). Everyone signs in at the same prompt: staff with the admin login, borrowers with their card number
+and password, the guest with the guest login.
+
+One simple page: a **Look up** box (books by title, author or ISBN, and people by name or card number), four big buttons
+(**Check out**, **Return**, **Add books**, **Add a person**) and **Recently added** books with their covers. The **menu**
+(top right) holds the rest: browse all books, lend / return, people and library cards, barcodes and settings, export / import,
+and a link to Koha's own staff screens. Borrowers and the read-only guest see just the lookup, recent books and (borrowers) My books.
+
+**Adding by title:** on Add books, scan or type an ISBN to add it straight away; type a title or author instead and you get a list
+of matches (cover, author, year, publisher) from Open Library and the Library of Congress to choose from. Books you already have
+are marked, with an *Add another copy* button.
+
+## Everyday use (details)
+
+One page for the day-to-day, so you rarely need Koha's own screens:
+
+- **Library**: a cover grid of everything you own. Search by title, author or ISBN; filter by shelf, format
+  (book/DVD/CD) and status (on the shelf / checked out); sort by title, author or newest. Click a book for its
+  page: copies with barcode, status, who has it and when it is due; change a copy's shelf or call number,
+  add another copy, remove a copy, or delete the book. (Title/author edits are one click away in Koha.)
+- **Lend / return**: scan or type a library card number (or search by name), then scan books to check them out;
+  "Return a book" takes a scan with no person needed; **Renew** extends a loan; the list below shows everything
+  that is out, overdue ones flagged. Check-in goes through Koha's own check-in code, so holds and rules still apply.
+- **People**: add someone with just a name (the card number is assigned automatically), search, and
+  **Print card** for a library card with a scannable Code 39 barcode.
+- **Add books**: scan an ISBN (or use the phone camera), as before.
+
+The read-only `guest` login only sees the Library and book pages (no copy status names, no editing, no lending).
+
+### Collections, QR cards, more about a book
+
+- **Collections** (Kids, Cookbooks, ...) are per copy, shown on the book page next to the shelf, and filterable on the
+  Library page. Choose **+ New collection...** (or **+ New shelf...**) in the dropdown to add one: no Koha screens needed.
+- **Library cards** carry a Code 39 barcode and a **QR code** of the card number. **Save as picture** makes an image to text
+  or AirDrop to a phone; on Lend / return, **Scan card or phone QR with camera** reads either one from a photo.
+  **Print everyone's cards** (People) lays out a sheet of cards.
+- **More about a book**: a description and subjects from Open Library, plus look-up links (Goodreads, LibraryThing,
+  WorldCat). **AR BookFind** is a link only: Renaissance's terms forbid automated access, so nothing is fetched from it.
+
+### Reading levels (AR) and spreadsheets
+
+AR BookFind has no public feed or import, and its terms forbid automated look-ups, so this site does not fetch from it.
+Instead: the book page has an **Open AR BookFind** link (plus **Copy title** to paste into its search) and boxes to record the
+**level, points and quiz number** you find there (the read-only guest sees them). **Library page -> Export / import** downloads
+`library.csv` (one row per copy, with any reading level) and imports a CSV of `isbn, level, points[, quiz]` you made yourself
+(for example from a spreadsheet or a Renaissance report you are entitled to export). Levels are stored in `reading-levels.json`
+in the Add books data volume, keyed by ISBN, so they survive a Koha reinstall and are included in the usual backups of that folder.
+
+### Live camera scanning (needs HTTPS)
+
+Browsers only allow a live camera on HTTPS pages (or on the machine itself). Put the library site behind Caddy with a real
+certificate and **Live scan** buttons appear: Add books (scan a stack of ISBNs one after another), Lend / return (live card or
+phone-QR scan, live book check-out for the chosen person, live returns). Chrome on Android reads codes in the browser; other
+browsers send small camera frames to the server's decoder a couple of times a second. On plain HTTP the photo buttons stay.
+
+### Copying reading levels from AR BookFind
+
+On the AR BookFind book page, select everything (Ctrl/Cmd+A), copy, and paste into the box on the book page here: the level,
+points, quiz number and interest level fill in by themselves; check them and press Save.
+
+### Tags, and borrowers signing in
+
+- **Tags**: any number per book (to read, kids, signed...). Add and remove them on the book page; click one to see every
+  book that has it; the Library page can filter by tag. They are stored in `tags.json` in the Add books data volume, which
+  the usual backups of that folder include.
+- **Borrowers sign in**: every person gets a login, **their library card number + a password**. Adding someone shows
+  their password once (a different easy one like `maple482`, or the same one for everyone: People -> *Sign-in passwords for new
+  people*). *Give everyone a sign-in* covers people added earlier; *New password* resets one person. A borrower who signs in
+  sees the library and a **My books** page: what they have out, when each is due (or overdue), **Renew**, and **Change my
+  password**. They cannot lend, edit or see other people. Passwords are Koha's own patron passwords; this stack relaxes Koha's
+  default strength rule (4+ characters instead of 8 with upper/lower/digit) once, at install or update.
+  Ten wrong guesses from one address locks sign-in attempts from it for five minutes.
+
+### Reading levels: pop-up or in-page AR BookFind
+
+The book page's AR box has **Open beside this page** (a pop-up window next to the book) and **Show it here** (AR BookFind inside the
+page; some browsers block its cookies inside another page, then use the pop-up). Either copies the title first so you can paste
+it into AR's search; AR's own page cannot be pre-filled from here.
+
+### 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`.
