# ytLlive — Task List

> **Catalog:** task files live in [`TASKS/`](TASKS/) (one file per task). This file is the
> index. Memory-map conventions: [`schema.md`](schema.md); architecture/decisions: [`ai.md`](ai.md).

> **Checklist markers** — every task's Status line uses the same states:
> 1. ✅ — completed / shipped
> 2. 🔶 — in progress
> 3. ⏳ — blocked / waiting
> 4. ☐ — not started / queued
> 5. ❌ — exception (known-issue, deliberately excluded, or merged)

> **2026-09-01 — v1 = feature-complete ruling:** there is no v1.x. Everything queues to
> v1 or to **"Out of product — permanently"** (file end). Read those two sections before
> adding or reviving anything here.

## Open items (at a glance)

### Creator-reported batch (2026-09-26) — proof-of-concept round, recordings used as the reference

The creator is **not** getting YouTube private test recordings saved, so local recordings are the
proof of concept for compositing; the live path is assumed to share it. **Verified true, not assumed:**
one `_framePump` is built in the `MainViewModel` ctor with a single `brandFlash:` callback, and BOTH
`Streaming.Operations.cs:68` (go-live) and `:199` (record) call that same `StartAsync` — there is no
second encoder path needing a "redirect". Record+simulcast is one ffmpeg with two outputs.

1. ✅ **Recording save dialog: Cancel discards** — was silently saving under the default name. Enter
   accepts the default; Cancel/Escape/X **deletes** the footage and names the file if the delete fails.
   `MainViewModel.CompleteRecordingSave` (internal) + `ytLive.Tests/RecordingSaveDialogTests.cs`.
2. ✅ **Brand flash in ALL scenes + in recordings** — was gated on `IsLive` via
   `UpdateLiveVisuals()`, so a recording made without ever going live carried no credit. The
   presenter is now `Start()`ed once in the `MainViewModel` ctor and never stopped on live-state
   churn; the licence gate rides on `IsPremium` → `Enabled` as before. Also fixed the
   premium-edge/restart trap that app-lifetime exposed. Tests: `BrandFlashOutputTests`
   (12 facts) incl. `Credit_IsComposited_WithNoLiveSession_AndSoARecordingCarriesIt` and
   `ADowngradeMidSession_RestartsTheCadenceTimer`.
3. ☐ **Ticker confined to the alert box.** The announcement strip is a **global 1920×48 top overlay**
   (`AlertOverlayLayer` comment + `BlitOverlay(…, 0, 0)`), but the creator wants it over the *Stream
   Alerts video* — i.e. inside the `SourceType.AlertBox` rect, in preview AND output. Needs a rect
   + scale/clip decision (see `ai.md`).
4. ☐ **Two instances still refuse to run.** `InstanceProfile` isolates layout/auth/log/WebView, but
   `FfmpegLocator._toolsDir` is still the hardcoded shared `%APPDATA%\ytLlive\tools` and both
   instances can `Directory.CreateDirectory` + `ExtractBinaries` into it. Also the launch method is
   unconfirmed: `dotnet run` while the first app holds `bin/…/ytLive.exe` dies with `MSB3027` before
   any instance starts — that is a build-output lock, not a log conflict.
5. ☐ **Post-session efficacy report** — on end of stream *or* recording, report what worked and what
   failed, including the **dropped frames** the creator saw. `CurrentHealth` already tracks
   `DroppedFrames`/`StreamDuration`; `SessionTeardownTests` is the natural home for the roll-up.
- **TASK 3** — items 16 (Text source) + 20 (RewardEvent capture → SQLite, Alerts' persistence half) open; **17 (Alerts) is DONE via TASK 43 (2026-09-24) — native six-event alert box**
- **TASK 9** — item 5 open (webcam identity key reconciliation)
- **TASK 10** — Velopack update URL pending
- **Shipping / release build (creator-queued 2026-09-26)** — no publish config exists yet:
  the csproj has only `OutputType=WinExe` + `TargetFramework`, so a plain `dotnet publish`
  is **framework-dependent** (customer needs the .NET 8 Desktop Runtime preinstalled).
  `Distribution.md` targets a self-contained ~80–120MB `LlamaCasty.exe` uploaded to Polar
  as a File Download benefit. Two deliverables:
  1. **`scripts/publish.sh`** wrapping
     `dotnet publish ytLive.csproj -c Release -r win-x64 --self-contained true -o ./publish/win-x64`,
     and **asserting the output contains no test/xunit artifacts**. (The compile side needs
     nothing — the tests are a separate project with a one-way reference, plus explicit
     `<Compile Remove="ytLive.Tests\**" />` in `ytLive.csproj`; the risk is *packaging*:
     `ytLive.Tests/bin/.../ytLive.exe` exists and would ship a Debug build + test DLLs if
     anyone ever zips a bin folder by hand. Never copy folders; always publish.)
  2. **Condition `InternalsVisibleTo("ytLive.Tests")` to Debug only** (`ytLive.csproj:78-82`
     is unconditional, so it ships in Release) — it hands the test assembly name to anyone
     decompiling and advertises that `internal` members are externally reachable, which
     conflicts with the obfuscation posture in `Distribution.md` §1.2.
  3. **Decide the shipped exe name.** `Distribution.md` promises the customer
     `LlamaCasty.exe`; `<AssemblyName>ytLive</AssemblyName>` actually publishes `ytLive.exe`.
     Renaming the AssemblyName is 4 lines (1 csproj + 3 pack URIs that spell the assembly
     name — `MainWindow.xaml:14` is the **window icon**, so missing it ships a broken
     taskbar/Alt-Tab icon). Namespaces stay `ytLive.*`; the 230-file re-brand is NOT
     wanted. Do **NOT** touch the `%APPDATA%\ytLlive` folder — breaking (orphans users'
     layout DB). See the naming table in `ai.md`.
  Do **NOT** add `-p:PublishTrimmed=true`: WPF is not trim-compatible and it fails at
  runtime (BAML/XAML resource resolution), not at build time. `PublishReadyToRun` is safe.
- **TASK 12** — queued future
- **TASK 13** — queued post-v1
- **TASK 14** — Branch 2 shipped; branch 3+ in progress
- **TASK 21** — UI picker slice remaining (Windows-only verification pending)
- **TASK 32–36** — all queued future work (2026-09-01)
- **Webcam resource lifecycle (2026-09-17)** — startup slice shipped (OS poll at start, single-camera
  auto-lock, persistent red alert in the Layers panel on lock failure, re-polls until resolved); gate
  slice shipped same day — webcam = app-level default, one per stream per scene, Add places the
  default directly, offered only when a camera is ATTAINABLE (identity + live session, not just a
  saved identity), app base lock keeps the session after the last placement is removed, startup
  adopts a solo camera as default. TASK 26's app-wide gate superseded by creator directive. The App
  Settings webcam selector is now **TASK 40 Unit A** (plan saved 2026-09-22). Remaining next slice
  (user-queued): static (+) catalog rows (Background, YouTubeEvent, quoted labels) with reason-greying.
- **TASK 40 — App Settings round** — plan saved 2026-09-22 (`TASKS/task-40-app-settings-round.md`),
  four units, one Good Dog test each: **A** active web camera section under Recordings (Change…
  sub-menu = live enumeration incl. vcams; Tune… config dialog via `ICameraControlProbe`, live-only
  tweaks), **B** gear moved top-left right of the wordmark (left-click App Settings, right-click
  Bug/Feature/About), **C** persist output resolution default + surface default scene
  transition/duration + confirm-before-End, **D** accent/theme color (consolidate 69 hardcoded
  accent sites into a DynamicResource brush + picker). **Unit B (gear) is DONE early** — shipped 2026-09-22
  as part of TASK 42 (top bar redesign): gear top-right of the brand, single click = the Settings/Bug/
  Feature/About menu, removed from BottomBar. A + C + D remain queued.
- **TASK 37** — queued (2026-09-20): split the layout data into a `default` set (the established DB)
  and a `current` set carrying the build-id; a saved `current` is honored only by the same build-id,
  otherwise defaults load — enables one-click revert to defaults too. Capture needed work OUT of
  current scope here; do not bolt it onto an in-flight change.
- **TASK 41 — Test Stream mode** — DONE 2026-09-22 (`TASKS/task-41-test-stream-mode.md`): a Test
  button next to Start runs the real private-only go-live pipeline with `IsTestStream` set, and the
  TEST drawer (right rail, third tab) hosts Mock Chat Input (real `liveChat/messages.insert` → ~2s
  poll round-trip renders on the overlay) + simulated Subscriber/New Member/Super Chat events that
  inject through the poller's `MessageReceived` seam (`IsSimulated` — YouTube's insert API only
  creates text, so these are local-only by design; styled member/SuperChat rows validate the chat
  overlay). **Real Stinger/TTS alert widgets resolved by TASK 43's native alert box.**
- **TASK 43 — Native events & alerts** — **DONE 2026-09-24** (`TASKS/task-43-native-alerts.md`):
  StreamElements replaced with NATIVE YouTube events. Chat parity half: `YouTubeChatService` now
  decodes all SIX `liveChat/messages` event types (`ChatEventKind` on `ChatMessage`) — the four
  formerly-empty event rows fixed — and re-arms its poll on the server's `pollingIntervalMillis`
  (streamList semantics, clamp 1000–6000ms, `maxResults=2000`). Alerts half: a new
  **`SourceType.AlertBox`** ("Stream Alerts", one per layout) is an OBS-style celebration zone
  where the six events play **six unique branded animations** (`AlertRenderer` + the
  `AlertOverlayLayer` component; 33ms ticker, deterministic `Advance` test clock; idle =
  transparent). Creator rulings baked in: free-sub mention = chat row only (no sub alert — YouTube
  emits none), NO viewer count, every alert card carries the "made with LlamaCasty!" brand line.
- **TASK 44 — TEST-tab chat fix** — **DONE 2026-09-25** (`TASKS/task-44-test-chat-fix.md`):
  the open creator report ("I still cannot post a chat message in the TEST tab") was a single
  cause: `GetBroadcastLiveChatIdAsync` read `contentDetails.liveChatId` (lifeChatId lives in
  **`snippet`**) AND ran before the broadcast was live (RTMP push flips ready→live via
  enableAutoStart; YouTube only populates the id on live broadcasts — official GetLiveChatId.java
  sample lists broadcastStatus=active). Fixed by reading `snippet.liveChatId` and polling with a
  bounded retry after the frame pump starts; chat stays non-fatal.
- **TASK 47 take four (2026-09-26)** — the announcement strip was **output-only** (a
  frame-pump callback with no preview consumer, since a master-width global overlay cannot
  ride a per-element `Image`) and the marquee was paced at a fixed `140px/s` (~17s per
  pass, so a 10s alert showed the text once). Now: a `tickerPreviewSink` publishes it to a
  global `AlertTickerElement` in `PreviewPane.xaml` (mirroring `SocialBarElement`), and the
  creator picks **Scroll / Flash / Solid** in the panel, with Scroll paced in *reads per
  alert* (3 inside a 10s alert) rather than px/s. 15 new facts; suite 339/339.
- **TASK 47 — Alert box video** — **DONE 2026-09-26** (`TASKS/task-47-alert-videos.md`):
  the TASK 43 alert box now plays a **video** on every alert — a shipped built-in mp4
  (`Assets/alert-default.mp4`, stamped into the `Asset` table at startup) that the creator can
  swap for their own file via the new Stream Alerts section (path only, never stored in the DB;
  six `AlertRenderer` animations remain the fallback). Per-alert decode via a new
  `IAlertClipDecoder` fx (ffmpeg rawvideo bgra + f32le pipes, real-time paced, disposed at
  drain); ~0.3s fade-in/out rides the alpha envelope + scales the audio (mixed into the live
  stream at unity — **no duck**, a per-alert Volume slider instead); an auto-composed message
  **ticker** ("Funder — Super Chat · $10.00") scrolls along the very top of the frame
  (never-baked dynamic overlay threaded through SceneCompositor + FramePump). Creator rulings:
  custom + fallback (not either/or), ticker on top, no ducking.

## 1.0 gates (do these before the first shipped build)

- **Kill the dev multi-instance affordance.** `Helpers/InstanceProfile.cs` is already entirely
  `#if DEBUG`, so a Release build ships as `DataRoot => DefaultRoot` / `WebViewDataFolder => null`.
  Nothing to do but *keep it that way* — and re-prove it:
  `InstanceIsolationTests.TheAlternateProfile_IsConfinedToTheDebugBuild` (source-level, always runs)
  plus a Release build in which the `InstanceVariable` **field** is absent from metadata.
  ⚠️ Do NOT grep the binary for `YTLIVE_INSTANCE` — consts are inlined and appear in neither build.
- **TASK 36 is now shipped** — the branding flash composites into recordings and the stream. Test
  VODs from an unlicensed instance carry the credit; use a license key for clean captures.
- Still queued from earlier: `scripts/publish.sh` (self-contained win-x64, no test artifacts,
  Debug-only `InternalsVisibleTo`, no WPF trimming), and the `LlamaCasty.exe` assembly rename
  (three pack URIs incl. `MainWindow.xaml:14` — do not rename `%APPDATA%\ytLlive`).
- Decide the open business question: `OverlayHost.xaml` copy says Polar unlocks *alerts* too, but
  alerts are not gated by `IsPremium`. Either fix the copy or gate the alerts — do not leave it.

## Out of product — permanently

These were explicitly ruled out:

- **D3D11 swap compositor** (superseded by software compositor; TASK 3 item 16)
- **Background removal** (ONNX/DirectML; TASK 3 item 19)
- **OBS-style source expansion** (game capture, browser source, media playlist, VLC, color-key, MIDI — the minimal source set is deliberate; creators who need more have graduated to OBS)
- **Multi-layout** (auto-save, single layout; multi-layout = OBS territory)
- **Cross-process stream resume** (API makes it impossible; creator ruling 2026-09-01)
