-3. **Sender** (tablet): **Send** → **same transport** → pick receiver → PIN → approve screen capture.

+# Alpha soak checklist (LAN demo)
+
+Manual QA on **two devices** on the same Wi‑Fi. Goal: stable show path without experimental transports or stream protection.
+
+## Before you start
+
+| Setting | Sender | Receiver |
+|---------|--------|----------|
+| Transport | **UDP** | **UDP** (must match) |
+| Stream protection | **None** | **None** |
+| Video codec | **H.264 (AUTO)** | **H.264 (AUTO)** |
+| Resolution (sender) | **720p** or **Auto** for first pass | — |
+| Multi-receiver | **One** receiver selected | — |
+
+PIN default: `1234` (change in settings if needed).
+
+## Happy path (~15 min)
+
+1. Install the same debug/release APK on both devices.
+2. **Receiver:** Main → **Receive** → **Start listening** (notification shows *Listening*).
+3. **Sender:** Main → **Send** → refresh discovery → pick receiver → enter PIN → approve screen capture.
+4. Confirm sender notification: *Casting via UDP · WxH*.
+5. Confirm video and audio on receiver for **≥ 5 minutes**.
+6. Rotate sender once; confirm stream recovers or stop/restart cleanly.
+7. Press **Stop** on sender notification; receiver returns to awaiting state.
+
+## Stress (optional, ~10 min)
+
+- Background sender app for 30s, return — stream continues or fails with clear status (no silent hang).
+- Lock/unlock receiver once during cast.
+- Second cast session without reinstall (stop → start again).
+
+## Pass criteria
+
+- No crash on either device during happy path.
+- Video appears within **10s** of capture consent.
+- Stop ends services and notifications on both sides.
+
+## If something fails
+
+| Symptom | Check |
+|---------|--------|
+| No video | Transport match; receiver listening first; open receiver UI once for surface attach |
+| Auth failed | PIN; same Wi‑Fi; firewall on LAN |
+| *Screen capture data missing* | Reinstall APK; Android 13+ consent intent |
+| Choppy only on UDP | Retry with **TCP** on both sides (fallback test) |
+
+## Not in alpha soak scope
+
+- QUIC / WebRTC / USB-tether transports
+- FEC / NACK stream protection
+- 1:N multi-receiver (unless explicitly testing)
+- OTA / crash upload (backend track)

 ### Alpha app checklist

- [ ] Happy path: UDP + H.264/AAC + single receiver, stream protection **None**
- [ ] README matches `CastSettings` / `CastConfig` defaults
- [ ] Fix misleading strings (e.g. camera “not implemented”)
- [ ] Two-device QA script (rotate, background, notification stop)
- [ ] Optional: cap multi-receiver at 1 for show, or soak 1:N
+- [ ] Happy path: UDP + H.264/AAC + single receiver, stream protection **None** — see [ALPHA_SOAK.md](ALPHA_SOAK.md)
+- [x] README matches `CastSettings` / `CastConfig` defaults (UDP default, resolution presets)
+- [x] Fix misleading strings (camera permission / API messaging)
+- [x] Two-device QA script — [ALPHA_SOAK.md](ALPHA_SOAK.md)
+- [x] Sender resolution UI: Original / 720p / 480p / Auto (release builds; legacy modes dev-only)
+- [x] Remove orphan `ReceiverActivity` (receiver entry is `ReceiverPlaybackActivity`)
+- [ ] Optional: cap multi-receiver at 1 for show, or soak 1:N — soak doc recommends one receiver
