The paid delta is output quality, so the rule needs to be measurable rather than a word:
921,600 pixels and 30 fps, fail-closed. Models/OutputProfile.cs is that rule as pure
policy — a permitted tier passes through untouched (Pro, or the free tier's own 720p30),
a disallowed one resolves to the best tier the budget allows and carries ITS bitrate, so
a capped user is never offered an 8 Mbps budget for a 720p frame.
Applied once, in BuildEncoderOptions. That is genuinely one place: the stream and the
local recording are two output blocks of ONE ffmpeg process fed by one EncoderOptions,
so there is no second encoder to forget. (commercial.md claimed "both encoders — never
two checks"; the code is stronger than the doc, and the doc is corrected.)
Developer override, as asked: a "Developer mode — all resolutions" checkbox in App
Settings, bound to MainViewModel.DeveloperMode, which feeds HasProOutput. It is not
hidden in a release build — Controls/DeveloperPanel's Page and Compile items are removed
when Configuration != Debug, and OverlayHost adds it at runtime inside #if DEBUG, so a
shipped exe has no BAML for it at all. The setter also refuses the value when
DevBuild.IsDevelopment is false, which is now the single source for that question (the
scoreboard partial had its own duplicate const).
Two traps worth their lines: a `const bool` dev flag makes `if (!Flag) return;` an
unreachable-code warning in one configuration or the other (CS0162), so DevBuild uses
static readonly; and a Condition on an ItemGroup is invisible to a test reading
item.Attribute("Condition") — read the parent.
Tests: 14 pass across OutputProfileTests, AssemblyIdentityTests and StorePackagingTests.
The invariant test is the one that matters: iterate every shipped tier under a free
entitlement and assert none emits more than the budget, so a future 4K tier fails here
instead of shipping to everyone. App builds Debug and Release at 0 warnings.
The creator (2026-10-30): the brand-logo field in App Settings showed only a file NAME, so a
myopic user could not confirm which picture was set. Now a 28x28 thumbnail sits left of the
field showing the actual image, and hovering it opens an enlarged copy (up to 420x320) beside
the panel with the file name underneath. A click collapses it; moving the pointer away closes
it, unless the pointer walked onto the popup itself, where it stays so the creator can look
closely.
Mechanics:
- `MainViewModel.BrandLogoPreviewImage` decodes the stored asset ONCE and freezes it, so the
thumbnail and the enlargement share one bitmap and no dispatcher hop is needed. A corrupt
image returns null instead of taking the dialog down.
- The thumbnail is hidden when no image is set (NotNullToVis), so there is nothing to hover and
no empty frame can appear.
- The popup is a separate window: WPF refuses to open one until its placement target is in a
live visual tree, which is why the test hosts the control in a real window rather than
asserting on a detached control.
Guard: BrandLogoPreviewTests — the wiring (image binding, the no-image gate, the four gesture
handlers, the readable enlargement size) and the control's open/close behaviour.
OverlayHost.xaml(.cs) takes the window-root overlay dialog grid (settings/
bug/feature/about panels); BackToAbout_Click moved in via inherited DataContext.
WebViewHostPanel + ToastArea stay as thin window-root stubs so the WebView2 ctor
init and NotificationService InArea('ToastArea') name lookups are untouched.
This completes Phase 2: MainWindow.xaml is now a 123-line shell.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in same commit.
