gramps 7827d239e2 docs(commercial): one source of truth for the money — prices, entitlement, channels 
The commercial plan was spread over five documents written in five different weeks,
and they contradicted each other: product.md sold the Store, decisions.md called the
Store dead then re-opened, Distribution.md (736 lines) still described Polar as a
download host, MARCOM.md quoted "no subscription" next to a paid tier, and README.md
promised "free forever". An outsider could not tell what ships.

docs/ai/commercial.md is now the only place money is decided: free = whole app at a
921,600 px / 30 fps output profile covering the recording as well as the stream; Pro =
$10/mo or $400 lifetime through Polar, key bound to the buyer's YouTube channel ID via
a claim page, 2 activations, 7–14 day lease with offline grace, fail closed, never
downgrade a running stream; one portable zip + winget primary, Steam and the Store
parked; Azure Trusted Signing (~$9.99/mo), no EV; Founding 200 promo; ~$135/yr costs;
anti-piracy posture and what is permanently rejected.

Everything else now points at it instead of restating it:
- product.md — money sections replaced with pointers; packaging rewritten to
  winget-first, Store parked; signing updated to Trusted Signing.
- decisions.md — graveyard with cause of death for free-forever, the Store ordering,
  the updater, and the 2026-10-30 reversal of the quality-ceiling rejection.
- Distribution.md — rewritten to release mechanics only (artifact, GitHub Releases,
  winget manifest, signing, checklist, takedown): 736 → 120 lines.
- TASKS.md — TASK 54 rewritten, TASK 48's route settled, TASK 10 superseded, five new
  rows (entitlement seam, output-profile gate, licence UI, system messages, packaging).
- README.md — "free forever" replaced with the real split.
- capture.md — obs-backgroundremoval is GPL-3.0 and so licence-INCOMPATIBLE since the
  proprietary EULA; the old "compatible" line was falsified by that change.
- TASKS/task-10, task-48, task-51, task-54 — superseded-banner at the top of each, so
  none of them reads as current policy.
- HANDOFF.md — rewritten: plan settled, next code unit is the entitlement seam.

MARCOM.md and MONETIZATION.md (gitignored) were corrected in place: policy pointer at
the top of each, the flash removed from every live claim, the Polar fee break-even
corrected to ~$900/mo, and the projections flagged as written against a dead model.

## What it is
A Windows-only WPF (.NET 8) app that live-streams to YouTube. Five fixed scenes
(Starting / Live / BRB / Chat / Ending), a pure C# software compositor over an always-1920×1080
master, a bundled-ffmpeg encoder pushing RTMP, and a WASAPI audio chain. Freemium — free is the
whole app at a 720p30 output profile, Pro buys higher output quality — under a proprietary EULA,
with no account creation: it links an existing YouTube channel. One-click go-live is the product;
OBS is the escape hatch for anything bigger.
## Build, run, test
Windows `dotnet.exe` from WSL; takes are read in **Release**. Full detail in
[`docs/ai/environment.md`](docs/ai/environment.md).
```bash
"/mnt/c/Program Files/dotnet/dotnet.exe" build "C:\Users\gramp\Documents\Code\projects\ytLive\ytLive.csproj"
"/mnt/c/Program Files/dotnet/dotnet.exe" run -c Release
"/mnt/c/Program Files/dotnet/dotnet.exe" vstest "C:\Users\gramp\Documents\Code\projects\ytLive\ytLive.Tests\bin\Debug\net8.0-windows10.0.19041.0\ytLive.Tests.dll"
```
`./scripts/verify.sh "<files>"` is the one pre-commit gate (doc budgets, clean build at 0
warnings, tests, scope).
## Architecture
C# / WPF (.NET 8) following MVVM:
| Path | Role |
|------|------|
| `Models/` | Plain data types — Scene, Source (incl. `ClipShape`, `IsMirrored`, `VideoImageSource`), QualityOption, StreamConfig, StreamHealth, YouTubeChannel, ChatMessage, **Socials (`SocialService` enum + `SocialEntry`/`SocialsConfig` + `SocialServiceIcons`) — the social bar** |
| `ViewModels/` | MainViewModel — `public partial class`, one file per functional area (Scenes, Background, Webcam, Audio, Trax, Socials, Streaming, Chat, Overlays, Account, License, Recording — split complete, see `ViewModels/index.md`); **Chat.cs is a thin delegating facade over `Services/ChatOverlayLayer.cs` (Commit G, first true decomposition), and now also over `Services/AlertOverlayLayer.cs` (TASK 43 — the native alert box, same true-component pattern)**; GoLiveViewModel, ReuseImageViewModel, CameraPickerViewModel, **SocialsDialogViewModel** |
| `Services/` | YouTube OAuth2, stream/broadcast management, live chat polling, LayoutStore (SQLite), **SocialValidator (`ISocialValidator` seam + `HttpSocialValidator` default)**, **webcam: `VideoFrame` seam + `CameraDeviceInfo`/`ICameraEnumerator`/`ICameraFrameSource` interfaces + `MediaCaptureCameraEnumerator`/`MediaCaptureFrameSource` (WinRT) + `CameraManager`**, **screen capture: `IFullScreenDetector`/`Win32FullScreenDetector` + `IScreenCaptureSource`/`ScreenCaptureFrameSource` (WinRT GraphicsCapture) + `ScreenCaptureManager` + `ScreenCaptureSourceFactory` + `Direct3D11Helper`/`CaptureInterop` (COM bridges)**, **media source: `IMediaFrameSource` + `MediaVideoSource` (spawns ffmpeg `rawvideo` BGRA decode) + `MediaVideoSourceManager` (refcount-by-path session owner) + pure `RawVideoFrameReader` + `IDecodeProcess`/`FfmpegDecodeProcess` process seam (binary-stdout mirror of `IEncoderProcess`; see [`TASKS/task-21-media-source.md`](TASKS/task-21-media-source.md))**, **compositor: `SceneCompositor` + `CompositorOptions` + pure `StretchMath` + `StaticPixelCache` (see [`docs/ai/frame-pipeline.md`](docs/ai/frame-pipeline.md) → "Scene compositor")**, **alerts: `ChatOverlayLayer` + `AlertOverlayLayer`/`AlertRenderer` (the native celebration-zone overlay, TASK 43 — see [`docs/ai/overlays.md`](docs/ai/overlays.md))**, **audio: `IAudioSource` seam + `WasapiLoopbackAudioSource`/`WasapiMicAudioSource` (NAudio WASAPI) + `AudioMixer` + pure `AudioLevelMeter`/`WaveToFloat`/`VoiceFilterChain`/`LowShelfFilter`/`HighShelfFilter`/`NoiseGate`/`Compressor`/`AutoDucker`/`AudioRingBuffer`/`TinyResampler`/`AudioSyncDelay` + `MusicPlayer` + `ITraxPlayer` (TRAX toggle seam — FakePlayer in tests; the dot is green/red/gray and the error scrolls terse in the desktop-audio bar; MusicVolume fixed 0.5) + `IAudioPipeWriter`/`NamedPipeAudioWriter` (see [`docs/ai/output.md`](docs/ai/output.md) → "Live audio capture")**, **encoder: `IFfmpegEncoder`/`FfmpegEncoder` + `IEncoderProcess`/`FfmpegEncoderProcess` + `IFfmpegLocator`/`FfmpegLocator` + pure `FfmpegArgs`/`FfmpegProgressParser`/`FfmpegEncoderPicker` + the `FramePump` frame producer (see [`docs/ai/output.md`](docs/ai/output.md) → "Live encoder" + [`docs/ai/frame-pipeline.md`](docs/ai/frame-pipeline.md) → "Live frame pipeline")**, **notifications: `INotificationService` seam (`AppNotificationSeverity` Info/Success/Warning/Error) + `NotificationService` (Notification.Wpf toasts, see "Toast notifications")** |
| `Helpers/` | ViewModelBase (INotifyPropertyChanged), RelayCommand, ImageCache, AppLog (file logger), FocusPreservingListBox, OAuthCredentials, **TokenStore (DPAPI session persistence)**, **BuildStamp (wordmark release counter `#N`, incremented by `GenerateBuildStamp` from the local `BuildCounter.txt`; per-build GUID/time are logged to startup.log)**, visibility converters |
| `Themes/` | `Controls.xaml` — the single dark-theme source, merged once in `App.xaml` (see `Themes/index.md`) |
| `MainWindow.xaml` | Dark theme; top bar + health banner; work area has a fixed 360px left column and preview column, top-left readouts/resolution and scene strip above preview, lower left panel + preview; bottom bar is an empty spacer |
## Where the truth lives
| Subsystem | File | Read when |
|---|---|---|
| Capture: backdrop, webcam, background effects, vertical tier | [`docs/ai/capture.md`](docs/ai/capture.md) | touching any frame source, the Background row, camera acquisition, or the 9:16 geometry |
| Compositor, render budget, frame pump | [`docs/ai/frame-pipeline.md`](docs/ai/frame-pipeline.md) | changing the render loop, per-frame cost, pacing, backpressure, or dropped/juddering frames |
| ffmpeg, encoder, recording, audio chain | [`docs/ai/output.md`](docs/ai/output.md) | ffmpeg args, REC/ON-AIR, the audio mix, loudness or sync |
| Social bar, alerts, chat overlays | [`docs/ai/overlays.md`](docs/ai/overlays.md) | anything drawn on top of the output |
| Go-live, broadcasts, health, chat API | [`docs/ai/youtube-api.md`](docs/ai/youtube-api.md) | go-live, broadcast lifecycle, health polling, streaming close-out |
| Control surface, theming, transitions | [`docs/ai/ui-surface.md`](docs/ai/ui-surface.md) | anything the creator looks at |
| Brand, packaging, legal posture | [`docs/ai/product.md`](docs/ai/product.md) | branding, naming, packaging behaviour, legal obligations |
| Prices, entitlement, channels, signing, promo | [`docs/ai/commercial.md`](docs/ai/commercial.md) | anything about money: pricing, licence keys, output cap, winget/Steam/Store, costs |
| Hosts, build commands, test map | [`docs/ai/environment.md`](docs/ai/environment.md) | building, running, adding a test |
| Routes for every subsystem | [`docs/ai/index.md`](docs/ai/index.md) | you want the full table with a "read when" per file |
Lookup, not reading: [`MyMistakes.md`](MyMistakes.md) (grep first on any "did this before?" wall) ·
[`TASKS.md`](TASKS.md) (the queue) · `TASKS/` (per-task detail and API research) ·
`<dir>/index.md` (per-directory map).
## Current state
[`HANDOFF.md`](HANDOFF.md) — branch, what's in flight, the next action, live landmines. Do not
restate it here.
