Subject: [PATCH] feat(tizen): Samsung Tizen TV web player (.wgt)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ports the ScreenTinker player to a Tizen TV / signage web app, speaking the
SAME /device socket.io protocol as the Android player — no server changes; a
Tizen display pairs from the same dashboard.

- app.js: device protocol client — register (pairing_code | device_id+token),
  device:registered/paired/unpaired/playlist-update, 15s heartbeat, keep-awake.
  Always reaches the server prompt until the display is actually paired; a
  saved-but-unreachable server falls back to the prompt (no blank screen); BACK
  returns to it.
- player.js: fullscreen single-zone renderer — image (duration timer), video
  (play-to-end + loop), YouTube (iframe embed), widget (iframe render endpoint).
- config.xml: Tizen TV manifest; build-wgt.sh packages (signs if Tizen CLI
  present, else unsigned); README covers URL-Launcher and signed-.wgt deploy.

Validated: headless protocol test vs the live server passed end-to-end
(register -> pair -> reconnect-auth -> playlist(2) -> content 200); loads +
renders in Chromium with no JS errors.

Not yet ported (fullscreen single-zone covers most signage): multi-zone, video
walls, screenshots, remote control, self-OTA. .wgt is a build artifact (gitignored).

+# ScreenTinker — Tizen TV Player (`.wgt`)
+
+A Samsung **Tizen TV / signage** web port of the ScreenTinker player. It speaks the
+**exact same `/device` socket.io protocol** as the Android player, so a Tizen
+display pairs and plays from the same dashboard with no server changes.
+
+## What it does
+- Enter a server URL → connects to `{server}/device` (socket.io v4).
+- Registers, shows a **6-digit pairing code**; you claim it in the dashboard
+  (Devices → Pair a display). On `device:paired` it switches to playback.
+- Reconnects automatically with a stored `device_id` + `device_token`.
+- Renders **fullscreen single-zone** playlists, looping:
+  - **image** → shown for `duration_sec` (min 3s)
+  - **video** (`/api/content/{id}/file` or `remote_url`) → plays to end, then next; single item loops
+  - **YouTube** (`mime video/youtube`) → muted autoplay `<iframe>` embed
+  - **widget** → `<iframe>` of `{server}/api/widgets/{id}/render`
+- Sends `device:heartbeat` every 15s (with best-effort Tizen telemetry).
+- Keeps the screen awake (`tizen.power` / Samsung `appcommon` screensaver-off).
+
+## Files

+js/app.js           device protocol client (register, pair, heartbeat, state)
+js/player.js        fullscreen playlist renderer
+js/socket.io.min.js socket.io-client v4.7.5 (bundled)
+icon.png
+build-wgt.sh        package (signed if Tizen CLI present, else unsigned)
+```
+
+## Build
+```bash
+./build-wgt.sh            # -> ScreenTinker.wgt
+```
+Without the Tizen CLI this is an **unsigned** `.wgt`.
+
+## Deploy — two paths
+
+### A) URL Launcher (easiest, no signing) — Samsung signage (SSSP)
+No package needed. Host this folder on any web server (e.g. the ScreenTinker
+server itself) and point the display's **URL Launcher** at `…/index.html`.
+The TV runs it as a web app on boot. Best for Samsung B2B signage displays.
+
+### B) Signed `.wgt` (retail TVs / installed app)
+Retail Tizen TVs require a Samsung-signed package:
+1. Install **Tizen Studio** + the TV extension.
+2. **Certificate Manager** → create a Samsung author + distributor certificate
+   (needs a free Samsung account; distributor cert must include the TV's **DUID**).
+3. Create a signing **profile**, then:
+   ```bash
+   ./build-wgt.sh <profileName>     # uses `tizen package -t wgt -s <profileName>`
+   ```
+4. Put the TV in **Developer Mode** (Apps → 12345 → enter host IP), then install:
+   ```bash
+   sdb connect <tv-ip>
+   tizen install -n ScreenTinker.wgt -t <tv-device>
+   ```
+
+## Validated (2026-06-09)
+- **Protocol**: headless test against the live server passed end-to-end —
+  `register(pairing_code) → device:registered → pair → reconnect(device_id+token)
+  → device:playlist-update(2 items) → GET /api/content/{id}/file = 200`.
+- **Runtime**: loads + renders in Chromium with no JS errors (setup screen verified).
+- Not yet on real Tizen hardware — needs signing + a TV (or URL Launcher).
+
+## Not yet ported (Android player has these; fullscreen single-zone covers most signage)
+Multi-zone layouts, video walls (`wall:sync`), screenshots, remote touch/control,
+and self-OTA (Tizen apps update via Samsung's store / URL Launcher refresh, not the
+Android `PackageInstaller` flow).
