TASK 5 items 1-3: reusable stream, health banner, docs refresh

Browse Source 
- Reusable stream: GetOrCreateReusableStreamAsync, cached via LayoutStore, bound at broadcast insert
- Health monitoring: GetStreamHealthAsync polls liveStreams.status, report-by-exception banner
- Go-live order: ensure stream → create broadcast → then start pump (URL must exist first)
- Full broadcast form scoped (TASK 5 items 6-7) in TASKS.md + ai.md
- TASK 23 trimmed to technical scope, TASK 26 added (marcom/launch kit)
- Confidential files: MONETIZATION.md + MARCOM.md (gitignored, not committed)
- .gitignore updated for confidential business files
- HANDOFF.md updated with session state and next steps

| File | Purpose |
|------|---------|
| `YouTubeAuthService.cs` | OAuth2 via Google: loopback callback (`http://localhost:8765/oauth2/callback`), token exchange, refresh, channel fetch. Constructor takes optional `HttpClient` + `sessionChanged` callback (test seam + save hook); session persists via `Helpers/TokenStore` (DPAPI); `ClearSession()` signs out (called by `MainViewModel.StopStream` on End Livestream) |
| `YouTubeStreamService.cs` | Broadcast/stream management via the v3 API (`enableAutoStart/Stop`). **`CreateBroadcast` always sends `privacyStatus = "private"`** (ship step 7 — private-only until v1; injectable `HttpClient? http = null` ctor seam so tests can fake the API and assert the forced privacy). **Not yet switched to the `variable` reusable stream** |
| `YouTubeStreamService.cs` | Broadcast/stream management via the v3 API. **`CreateBroadcast` always sends `privacyStatus = "private"`** (ship step 7 — private-only until v1) and the one-click v3 flags (`enableAutoStart/Stop`, `enableMonitorStream=false`, `latencyPreference=low`); injectable `HttpClient? http = null` ctor seam so tests can fake the API. **`GetOrCreateReusableStreamAsync` (TASK 5, shipped 2026-08-16)** returns the channel's `ReusableStream` — lists `liveStreams?mine=true` and reuses the existing `cdn.isReusable` stream, inserting once only on first use (`resolution=variable`, `frameRate=variable`, `isReusable=true`); a stream id given to `CreateBroadcast` binds at insert via `contentDetails.boundStreamId`. RTMP URL = `ingestionAddress + "/" + streamName`. **`GetStreamHealthAsync(streamId)` (TASK 5 item 3, shipped 2026-08-16)** polls `liveStreams?part=status` → `StreamHealth` with parsed `configurationIssues[]` |
| `StreamHealthReporter.cs` | Pure report-by-exception decision (TASK 5 item 3): `BannerFor(issues)` → `HealthIssueReport(Text?, IsError)` — null text on good/ok/noData/info-only, first warning/error issue produces its type text, error beats warning for color |
| `YouTubeChatService.cs` | Polls `liveChat/messages`, raises `MessageReceived`; `IDisposable` |
| `LayoutStore.cs` | SQLite persistence (`Microsoft.Data.Sqlite`) at `%APPDATA%\ytLlive\ytLlive.db`; assets stored as BLOBs keyed by SHA-256 content hash; save/open layout files; schema `user_version` 6 (`Source.ClipShape`/`IsMirrored` via `ALTER TABLE` for pre-v2 DBs; v3 = singleton `Webcam` + per-scene `WebcamSceneConfig`, migrated idempotently **without backfill** — the stale `Source.DeviceId` column remains but is no longer read/written; v4 = `WebcamSceneConfig.RectWidth`/`RectHeight`, the pre-Round rect for the round-to-rect restore; v5 = `Source.IsBackdrop` + `Source.CaptureKey`, the live-capture backdrop; v6 = `Scene.HasBackdrop` — Live-only policy, one-time backfill turns Starting/BRB/Chat/Ending off + drops their backdrop sources; `MainViewModel.EnforceBackdropPolicy` re-normalizes on every load) |

Settings key/value table holds app state: `MicSourceName`, `ReusableStream` (TASK 5 — the cached reusable stream's id/address/name so the pump has its RTMP URL at startup) |
| `VideoFrame.cs` | Normalized CPU frame seam (`Width`/`Height`/tightly-packed BGRA `byte[]`) — the only pixel type the rest of the app knows about; future capture sources (screen, background-removed webcam) feed the same seam |
| `CameraDeviceInfo.cs` | `(Id, DisplayName)` for a physical capture device |
| `ICameraEnumerator.cs` | `GetCamerasAsync()` — seam so the picker/`CameraManager` never touch WinRT (tests inject fakes) |
