Two related deliverables addressing the user's morning asks.
1. Branding: Dragon WHITE.png and Wild Dragon Logo WHITE.png from the brand kit are copied into src/TeamsISO.App/Assets/ and registered as <Resource> items in the .csproj. The rail's placeholder 'W' glyph is replaced by the real dragon mark (40x40, HighQuality bitmap scaling) with a 'Wild Dragon' caption underneath.
2. NDI Access Manager automation: NdiAccessManagerConfig service reads/writes %APPDATA%\\NDI\\ndi-config.v1.json, working in JsonNode trees so we don't clobber unrelated keys. ApplyTranscoderTopology() sets groups.send=[teamsiso-input] and groups.recv=[public, teamsiso-input] so all local senders (Teams + anything else) broadcast on the private group while local receivers can still see public sources too. Engine-side, the user's per-pipeline OutputGroups override pushes TeamsISO outputs back onto Public so downstream switchers see clean ISOs.
Atomic write: temp + replace, with timestamped backup of the prior config. ReadCurrentGroups() can be used by future UI to show what's currently configured. RestoreDefaults() reverts.
Settings panel grows an 'Apply transcoder topology' button under the NDI Network section. Click writes the system config, sets the engine's discovery=teamsiso-input / output=public, refreshes the bound text boxes, and pops a dialog with a 'restart Teams' reminder + the backup path.
First step of Phase E.1 from the new spec at docs/superpowers/specs/2026-05-08-embedded-teams-orchestration.md: a third icon in the left rail launches the Microsoft Teams desktop client as a subprocess of TeamsISO so the operator doesn't have to leave the app to start a meeting.
Services/TeamsLauncher tries the ms-teams: URI first, falls back to %LOCALAPPDATA%\\Microsoft\\WindowsApps\\ms-teams.exe (new Teams), then the classic Update.exe handoff. On failure surfaces a friendly MessageBox with the install link.
The spec doc lays out the full three-phase roadmap (launcher -> window orchestration -> in-app meeting controls via Graph API or UIAutomation) and explicitly calls out what's out of scope (replacing Teams' media stack).
_NEXT.md updated to mark Phase D done and queue Phase E + remaining polish items (code-signing, Inter/JetBrains Mono font bundling, real Wild Dragon dragon-mark, drops counter, running-fps display).
MainWindow drops the standard Windows title bar (WindowStyle=None + WindowChrome with CaptionHeight=44, ResizeBorderThickness=6, UseAeroCaptionButtons=False) and draws its own minimize / maximize-restore / close buttons inline in the existing header strip. The custom buttons opt into shell:WindowChrome.IsHitTestVisibleInChrome=True so clicks fire on them rather than starting a window drag.
Result: the entire top of the window is now ours, matching the Microsoft Teams desktop client's flush header look. The 'TeamsISO + by Wild Dragon' branding sits at the same baseline as the engine-status pill and the caption controls, and dragging anywhere not occupied by an interactive widget moves the window.
Caption-button styles in the theme: 46x32 hover-tinted, with the close button turning the Windows 11 #C42B1C red on hover. Maximize-button glyph swaps between the single-rectangle and overlapping-rectangles variants on StateChanged.
Drive-by: ParticipantViewModel.{FramesIn,FramesOut,IncomingResolution} setters dropped from private to public so {Run Text=...} bindings (which default to TwoWay on Run) can attach without WPF throwing 'cannot work on read-only property'.
IsoPipeline now publishes refs to its currently-live NdiReceiver and NdiSender (set by RunInnerPipelineAsync, cleared on exit) so a stats poll from any thread can read FramesCaptured / FramesSent without entangling the pipeline's lifetime with its observer. The receiver's raw-frame channel is wrapped with a TappedChannelWriter so the most recent RawFrame is captured for source-resolution display, again without changing the receiver's contract.
IsoController.GetStats() drops the stub return-Empty and instead reads the live pipeline.GetStats() outside the gate so a slow stats read can't serialize the controller's other operations.
WPF: MainViewModel runs a 1 Hz DispatcherTimer that pulls stats for every participant view-model and pushes them via UpdateStats(). ParticipantViewModel grows three displayable properties — FramesIn, FramesOut, IncomingResolution — bound into the participants DataGrid as a new 'Live' column showing the down/up frame counts and the source resolution underneath the machine name.
Tests: 74/74 unit + 9/9 NDI integration green; the existing round-trip integration test exercises the new wiring at runtime (live receiver/sender refs are set, frames flow, channels close cleanly).
Replaces the Stone theme with Wild Dragon branding (canvas #0A0A0A, accent cyan #97EDF0, secondary #9AE0FD, coral alert #FB819C — sourced from wilddragon.net) and reorganizes MainWindow into a Microsoft Teams-style three-column layout: a 72px left rail (logo + Participants/Settings nav + engine-status indicator), a center content area (header + participants card), and a right settings panel.
Adds InitialsConverter so participant avatars render real initials (Brendon Power -> 'BP', '(Local)' -> 'L') instead of a generic glyph. Drops the obsolete StoneTheme.xaml; the project now ships exactly one theme dictionary.
Typography: Inter (with Segoe UI Variable Display fallback) for the sans stack, JetBrains Mono (Cascadia Mono fallback) for machine names and timecodes — matching the wilddragon.net site.
Verified live against the running Teams meeting: app launches, participant 'Brendon Power' displays with avatar, settings panel surfaces NDI groups + Hide-Local toggle, engine status pill shows green/live.
Adopts the design language from Dammyjay93/interface-design: warm Stone neutrals, accent orange (#EA580C), borders-only depth (no shadows), 8px spacing grid, all-caps section labels, mono typography for machine names and timecodes.
Themes/StoneTheme.xaml is the single source of truth for design tokens (color brushes, typography styles, spacing) plus restyled control templates (Button, TextBox, ComboBox, ComboBoxItem, CheckBox, DataGrid + DataGridColumnHeader / DataGridRow / DataGridCell, ScrollBar). MainWindow consumes the tokens and is laid out with a header (title + status pill), section-headed Settings sidebar (Output Format / NDI Network / Display), card-wrapped participant list, and a mono status footer.
Settings sidebar surfaces the new NDI group configuration (discovery + output) and a Hide-(Local) checkbox. The latter filters the user's own self-preview from the participants list at the MainViewModel layer (HideLocalSelf=true by default) so operators don't accidentally route their own preview as an ISO. Apply Changes round-trips both FrameProcessingSettings and NdiGroupSettings through the controller in one go.
- TeamsISO.App: hand-rolled net8.0-windows WPF csproj since the WPF
template isn't shipped on linux-arm64 .NET SDK; UI is a placeholder
for Phase C.
- TeamsISO.Engine.IntegrationTests: cross-platform xunit project with a
skipped scaffold fact tagged [Trait("requires", "ndi")] for Phase B.
- TeamsISO.Linux.slnf: solution filter for non-Windows CI that excludes
the WPF project (which can only build on Windows).
