The bar now renders ONE surface from the FIRST decision the creator makes — Record or Stream — with each world being the whole bar. Creator directive: "I wrote the fucking thing and I still can't figure-out how to do stuff", "forget this one dog plan bullshit". OBS/streaming-tool reference for the one-surface paradigm: https://obsproject.com (single mode toggle + context actions) — cited per spin-guard habit; the go-live/test pattern follows CEV (https://cev-desktop.aSean.xyz) precedent. - Mode: single segmented REC|ON-AIR switch (SegmentToggle/SegmentLabel in Themes/Controls.xaml); radio-exclusive world selection, one tap to flip. - Record world: switch + Start Recording, zero YouTube identity. - Stream world: switch + Go Live + Test + account zone right (Sign In until connected, then avatar with Change Account/Logout context menu). - Test is a child of Stream: procs only stream-armed AND signed-in. - Running: one reality line "dot word elapsed" (REC/LIVE/TEST; green/red/ gold) + End; worlds + switch retire. - Gear moved up from bottom bar, ~3 wordmark letters past the brand, single click opens Settings/Bug/Feature/About menu (TASK 40 Unit B shipped early). - Fix folded in: BeginTestStream now arms OnAirPillOn explicitly (unarmed pump booted with zero encoder outputs -> "At least one output is required" forced-stop cascade from TASK 41's pipeline). - VM: world/reality props + RaiseTopBarModes() wired into StreamStatus, pill, IsRecording, IsTestStream, IsConnected setters. Doc: ai.md top-bar model, ViewModels/index.md, Controls/index.md, TASKS.md, HANDOFF.md, new TASKS/task-42-top-bar-redesign.md; task-40 note. Tests: TopBarModeTests.cs (new Good Dog), PillRadioTests + TestStreamTests gates updated. Build 0 warnings; full suite 314/315 — single abort is the pre-existing env-dependent RealMouseDrag test (Path of Exile 2 running)

# Controls — index
|
||
|
||
The phase-2 carved pieces of what used to be one monolithic `MainWindow.xaml`
|
||
(1,681 lines → a 123-line shell). Each is a `UserControl` in the `ytLive.Controls`
|
||
namespace, extracted one roll-back commit at a time (refactor-commit-12..18).
|
||
See [`schema.md`](../schema.md) for the memory-map conventions.
|
||
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `BottomBar.xaml(.cs)` | Footer (Row 3): stream stats (bitrate/fps/dropped/duration/health), resolution dropdown (gear menu moved up to TopBar 2026-09-22) |
|
||
| `HealthBanner.xaml(.cs)` | Row 1 status banner + the 7 value→visibility converters live in the app theme, not here |
|
||
| `TopBar.xaml(.cs)` | Row 0 session surface (2026-09-22 redesign): brand + gear menu (left), one segmented REC|ON-AIR mode switch + world actions (Record: Start Recording · Stream: Go Live + Test) + reality line while running (dot/word/elapsed) + End (center), account zone — Sign In or avatar w/ Change Account/Logout context menu (right). `RefreshAvatar()`, `GearButton_Click` |
|
||
| `PreviewPane.xaml(.cs)` | Row 1 Col 1 center: the 1920×1080 `OverlayCanvas`/`SelectionOverlay`/`BrandFlashLayer`/`SocialBarElement`, text pull-out drawer, and the live-controls row (TRAX / game / mic meters + sliders + speakers + socials) |
|
||
| `SceneThumbnailStrip.xaml(.cs)` | Row 0 scene-picker strip (`ItemsControl` over `Scenes`), staged-red / live-green border highlight |
|
||
| `LeftPanel.xaml(.cs)` | Row 1 Col 0 left panel: edit mode → layers+properties; live → YouTube chat. Source add/edit/remove, list drag-to-reorder, snapshot revert-accept |
|
||
| `OverlayHost.xaml(.cs)` | Root-grid overlay dialogs: Settings / Report Bug / Feature Request / About (+ licenses + license-key entry). `BackToAbout_Click` lives here |
|
||
| `SceneThumbnailStrip.xaml.cs` | Code-behind for the strip above |
|
||
| `LeftPanel.xaml.cs` | Code-behind for the panel above |
|

||
## Window ↔ control contract
|
||
|
||
The shell (`MainWindow.xaml(.cs)`) wires up each control and routes the few
|
||
cross-cutting calls through it:
|
||
|
||
- Ctor finds each control by `x:Name` (`TopBar`, `PreviewPane`, `LeftPanel`)
|
||
AFTER `InitializeComponent`, **before** any method touches it (null-ref guard).
|
||
- `_previewPane.IsClickInsidePreview/Drawer` + `_leftPanel.IsClickInside` →
|
||
deselection guard in `Window_PreviewMouseLeftButtonDown`.
|
||
- `_previewPane.UpdateSelectionOverlay(bool)` + `_leftPanel.OnSelectionChanged(vm)`
|
||
→ selection/edit-mode routing from the VM's `SelectedElement` change.
|
||
- `_topBar.RefreshAvatar()` on `IsConnected`/`AccountAvatarUrl` change.
|
||
- Handlers in moved controls cast `(DataContext as MainViewModel)` — controls
|
||
inherit the window's DataContext; never pass the VM through a property.
|
||
|
||
## Gotchas learned the hard way
|
||
|
||
- **A UserControl cannot see `Window.Resources`** (StaticResource resolves by
|
||
element lookup, so it stops at the control boundary). The 7 converters
|
||
(`BoolToVis`, `InverseBoolToVis`, `NotNullToVis`, `NullToVis`, `HiddenBoolToVis`,
|
||
`EnumToBool`, `AllTrueToVis`) were promoted from `MainWindow.Resources` into
|
||
`Themes/Controls.xaml` (see [`Themes/index.md`](../Themes/index.md)).
|
||
- **Moved XAML can lose its namespace**: a block cut from MainWindow carries no
|
||
root xmlns, so any `models:`/`Helpers:` ref in it breaks the build with
|
||
`MC2000: Value cannot be null (key)`. Declare `xmlns:models` / `xmlns:Helpers`
|
||
on each control's root (LeftPanel hit this).
|
||
- **Name-looked-up host stubs must stay in the window**, not a control:
|
||
`WebViewHostPanel` (ctor `InitWebView2(WebViewHostPanel)`) and `ToastArea`
|
||
(`NotificationService.InArea("ToastArea")`) are resolved by name from the
|
||
window root — so `OverlayHost` deliberately leaves them as thin window-root
|
||
children (Commit 18). Since the 2026-09-14 composition-capture redesign only
|
||
`ToastArea` remains — `WebViewHostPanel` is deleted (web sources no longer
|
||
host a multiline XAML control; `InitWebView2()` runs from `MainWindow_Loaded`
|
||
with no panel argument).
|
||
- When cutting visual wrappers, don't drop the outer `Border`'s
|
||
background/glow/margin — Commit 15 initially lost the preview's outer border
|
||
and had to restore it same-commit.

controls bind to), [`Themes/index.md`](../Themes/index.md) (styles/converters),

||

|
||
`MainWindow.xaml` shell at repo root that hosts these.
