# HANDOFF — Session State
## Branch
`main` — dirty (all changes uncommitted, builds clean)
`main` — clean, uncommitted TASK 10 changes
## What shipped this session
1. **Show Desktop toggle on Live backdrop** — `Source.ShowDesktop` bool persisted in DB (schema migration + read/write in LayoutStore). When checked, the primary monitor captures regardless of fullscreen game state. Toggling off falls back to the running game or releases to the static placeholder. `ClearBackdropCaptureAsync` clears `CaptureKey` + `VideoImageSource` so the static fallback actually renders.
1. **TASK 10 — Polar billing + Velopack auto-updates (steps 1–7)** — full license key activation flow:
- **Velopack** — NuGet `Velopack` 1.2.0 added, bootstrap in `App.xaml.cs` (`VelopackApp.Build().Run()` in try/catch). Self-hosted update URL TBD (DO droplet). The bootstrap is a no-op until the update URL is configured.
- **PolarLicenseService** — `Services/PolarLicenseService.cs`: `POST .../validate` with `key` + `organization_id`. Returns `status` (`granted`/`revoked`/`expired`) + `expires_at`. No auth. Network errors surfaced gracefully.
- **License key entry UI** — About overlay gains a third panel (same pattern as Licenses): text input + "Activate" button + status message. "Enter License Key" button added to the hub (alongside "Unlock Premium" which opens the Polar checkout URL). `IsHubVisible` computed property hides the hub when either sub-panel is open.
- **Entitlement persistence** — `LayoutStore` gains `LoadLicenseKey`/`SaveLicenseKey`, `LoadLicenseValidatedAt`/`SaveLicenseValidatedAt`, `LoadIsPremium`/`SaveIsPremium` via the Settings key/value table (no schema version bump needed). 14-day offline grace period: cached premium state trusted while online re-validation runs in the background.
- **BrandFlash toggle** — `IsPremium` property setter flips `BrandFlashEnabled = !value`. On startup, `ValidateLicenseAtStartupAsync` loads cached state → attempts online re-validation → overrides cache on success → lapses on failure/expiry. Premium removes the watermark; free tier keeps it.
- **PremiumUrl wired** — set to `https://buy.polar.sh/polar_cl_ueMy8AyAClO0o0yo19IroZwKTbD587gzUsjEW3bFapw`. `IsPremiumAvailable` now true. About overlay "Unlock Premium" button lights up. Tooltip updated.
- **About text updated** — "one-time unlock" → "subscription".
2. **Top bar — status light + avatar + Log In button** — red/green/pulsing ellipse (disconnected/connected/live). Avatar border visible only when connected, loads via `BitmapImage` in code-behind (not XAML binding). "Log In" button visible when disconnected, calls `StartStreamCommand` which opens GoLiveWindow with the sign-in flow. `ShowStartStream` now requires `IsConnected` too.
3. **Chat preview — one-at-a-time mock messages** — `RunMockChatPreviewAsync`: simple async loop, displays `MockChatMessages[n]` via `UpdateChatBoxPreview(chatBox, Take(n+1))`, 1000ms between messages, wraps at end. `ChatPreviewEnabled` property on Source (default true). Stops when real messages arrive, restarts on fade timer clear.
4. **Default backdrop seeds for all scenes** — `SeedEndingBackdrop` replaces existing (not skip-if-exists). `SeedChatBackdrop` added. `EnsureDefaultBackdrop` called on every scene switch — if a scene has no background, seeds the default from `Assets/`. Removed Chat skip from EnsureDefaultBackdrop.
5. **New backdrop assets** — `ending-backdrop.jpg` and `chat-backdrop.jpg` added to Assets + csproj as `<Resource>`.
6. **SceneCatalog fix** — Chat scene display name corrected to "Chat" (was "YouTube Chat" — that name belongs to the layer/SourceType.ChatBox, not the scene).
7. **Left panel spacing + context menu reorder** — HR margins matched, Row 4 changed from `*` to `Auto`, context menu items reordered (Border Thickness first).
8. **Border animation rendering** — code-behind Storyboard approach via `_activeBorderAnimations` dictionary, `FindBorderShape`, `CreateBorderAnimation` for all 9 types.
2. **Polar MCP auth** — authenticated via `opencode mcp auth Polar`. Polar MCP connected.

## Build
```bash
taskkill.exe /F /IM ytLive.exe # if running
"/mnt/c/Program Files/dotnet/dotnet.exe" build "C:\Users\gramp\Documents\Code\projects\ytLive\ytLive.csproj" --no-restore
```
## Known issues
- YouTube session expired at 11:45 — need to re-sign-in via the new "Log In" button
- Build often fails when ytLive.exe is running — `taskkill.exe /F /IM ytLive.exe` first
- `Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback` integration test is flaky in headless CI
## Next steps
1. **TASK 10 + Velopack** — license validation + auto-updates (1 full session)
2. **TASK 20** — hotkeys (global keyboard shortcuts)
3. **TASK 19** — scene transitions (Cut/Fade/Move/Custom)
4. **TASK 21** — media source (video file playback)
5. **TASK 22** — audio sync offset
6. **TASK 23** — studio mode
**0 warnings, 0 errors.**
