New AutoRecordOnCall preference (DISPLAY tab). When checked, recording auto-flips ON the moment Teams transitions into a call (UIA Leave button appears in tree), and auto-flips OFF when the call ends.
Completes the unattended-show story: with Launch + AutoHide + AutoRecord all ticked, the operator launches TeamsISO and walks away — Teams runs invisibly, recording begins/ends with the meeting, ISOs route, all done. Toast surfaces each transition so they know what's happening if they glance at the screen.
Implementation: transition detection lives in the existing UIA-probe code in OnStatsTick. previousInCall != inCall gate prevents the auto-toggle from re-firing on every poll. Direct call to _controller.SetRecording + Settings.RecordIsosToDisk = ... so the existing recording infrastructure handles the rest. Toast for visibility, swallow-on-error so a recording config issue can't break the IN-CALL pill update path.
The IN-CALL pill now reads 'IN CALL · Weekly Standup' (or 'IN CALL' if Teams' window doesn't expose a meeting title), so operators using auto-hide know WHICH meeting they're in without restoring the Teams window.
Implementation: TeamsLauncher.GetActiveWindowTitle uses EnumWindows + GetWindowTextW to read every Teams top-level window title (hidden windows too — title bar text is accessible even with SW_HIDE), picks the longest as a heuristic for 'most informative' (Teams creates several windows per process; the call window has the meaningful title). MainViewModel.ExtractMeetingTitle strips the ' | Microsoft Teams' / ' - Microsoft Teams' suffix variations and clamps overly long titles to 50 chars with an ellipsis.
10 new unit tests for ExtractMeetingTitle covering: standard formats with both separators, bare 'Microsoft Teams' (returns empty so the pill stays at 'IN CALL'), long-title truncation, outer-whitespace trimming, unrecognized formats passing through.
169/169 tests passing.
Adds a small URL input + Join button to the IN-CALL bar. Operators paste a https://teams.microsoft.com/l/meetup-join/... or msteams:/l/meetup-join/... link, click Join, and Teams launches into the meeting in one shot. Eliminates the open-Teams → Calendar → find meeting → click join dance — operators get meeting links from email/Outlook and can now join straight from TeamsISO.
TeamsLauncher.TryJoinMeeting validates the URL targets Teams (only http(s) URLs containing teams.microsoft.com / teams.live.com, or msteams: deep-links — won't shell-exec arbitrary clipboard contents). On success, integrates with AutoHideTeamsWindows so the Teams meeting window briefly appears then vanishes; operator is in the call, driving routing from TeamsISO.
VM-side: MainViewModel.JoinMeetingCommand + JoinMeetingUrl two-way bound. Field clears on success; warn-toast on failure with the specific reason (empty / not-a-teams-url / launch-failed).
Operators using auto-hide Teams couldn't tell whether they were in a meeting without restoring the Teams window. New status pill in the IN-CALL bar header shows:
• empty when Teams isn't running
• 'READY' (gray dot) when Teams is running but not in a call
• 'IN CALL' (cyan dot) when Teams is in an active meeting
Detection: TeamsControlBridge.IsInCall() walks Teams' UIA tree looking for the Leave / Hang-up button. Present iff in a call — works across Teams versions because Teams only exposes the Leave control while a call is active. Same candidate-name list the LeaveCall command uses, with localized strings for EN/DE/ES/FR/PT/JA already in place.
Polled at the existing 1Hz stats tick. UIA traversal can take 50-200ms in a busy call, so the probe runs off-thread; the property update is dispatched back via _dispatcher.InvokeAsync. Failure paths swallow exceptions — a flaky UIA call must never crash the stats timer.
159/159 tests passing, 0 warnings, 0 errors.
Two new persisted preferences in DISPLAY settings, paired to give operators the 'launch TeamsISO, never see Teams' experience the user asked for:
- LaunchTeamsOnStartup: TeamsISO auto-starts Teams in the background each launch (fire-and-forget background task in App.OnStartup, after the main window has materialized so a slow Teams launch doesn't delay the UI).
- AutoHideTeamsWindows: as soon as Teams' windows materialize after launch, hide them. New TeamsLauncher.AutoHideAfterLaunchAsync runs a polling loop (250ms / up to 15s) that catches the splash, main window, and any follow-up panels Teams opens. Teams takes 2-5s to render its main window and the splash arrives separately, so a one-shot hide right after launch wouldn't be enough.
When TeamsISO starts and Teams is already running (from a prior session), the auto-hide path still fires so the 'I only see TeamsISO' rule applies even when Teams was launched externally.
Operator drives everything through the IN-CALL bar (mute / camera / share / leave / marker) + participants DataGrid (ISO routing). Eye-toggle in the rail still restores Teams windows on demand.
Both toggles default to off — opt-in. Persisted via UIPreferences so they survive process restart.
Two user-reported bugs:
1) CheckBox content was clipping in the 380px settings panel ('Control surface (Stream Deck / Companion / w...' / 'LAN-reachable (allow other machines on yo...'). The Wd.CheckBox template used a horizontal StackPanel which doesn't bound child width, so long Content strings ran off the column without wrapping. Replaced StackPanel with a Grid (Auto + *) and injected a TextBlock style with TextWrapping=Wrap into the ContentPresenter resources — when WPF auto-wraps a string Content in a TextBlock, the resource lookup gives it Wrap.
2) The rail Launch Teams button ambushed operators: clicking with Teams already running (which is common when the eye-toggle has hidden Teams' windows) opened a 'Close all Teams windows now?' dialog. Operators expect Launch to mean 'show me Teams', not 'stop Teams'. Split the actions:
- Left-click: Teams not running → launch; Teams hidden → restore + foreground; Teams visible → bring to front. Always idempotent-progressive.
- Right-click: ask to stop Teams (preserves the kill path for those who want it).
TeamsLauncher.TryLaunch now collects per-attempt errors instead of swallowing them — a real failure surfaces 'ms-teams: URI → <reason>' / 'AppsFolder shell → <reason>' / 'classic Update.exe → not found at <path>' so 'No Teams found' isn't a black box.
Also added a 2nd path: explorer.exe shell:appsFolder\\\\MSTeams_8wekyb3d8bbwe!MSTeams (AppX activation via the OS's own Start-menu verb) as a fallback if the URI handler is misconfigured. Removed the broken bare-stub call to %LOCALAPPDATA%\\\\Microsoft\\\\WindowsApps\\\\ms-teams.exe — that's a 0-byte AppX placeholder that never worked outside an AppX context.
When the new ControlSurfaceLanReachable preference is on, both the REST/WebSocket control surface and the OSC bridge bind to all interfaces (http://+:port/ via HttpListener wildcard, IPAddress.Any for OSC) instead of loopback. The settings VM persists the toggle, restarts both surfaces when flipped, and surfaces a ControlSurfaceUrl computed from the first non-loopback IPv4 + a Copy button so operators can paste the URL onto a control PC.
Use case: a headless host PC runs Teams + TeamsISO; a thin client on the same LAN drives it via /ui or a Stream Deck. Closed-network deployment, no auth — documented as a trusted-LAN-only mode in docs/CONTROL-SURFACE.md, including the one-time 'netsh http add urlacl url=http://+:9755/ user=Everyone' requirement and the firewall rule.
Four polish items + a test pass.
1. Inter Variable (rsms/inter v3.19, OFL) is bundled at Assets/Fonts/Inter.ttf (~800 KB) and registered as a WPF Resource. WildDragonTheme.xaml's Wd.Font.Sans now points at pack://application:,,,/Assets/Fonts/#Inter so the typography matches wilddragon.net regardless of whether the user has Inter installed system-wide. Falls back to Segoe UI Variable Display if the resource is missing.
2. 'Stop all ISOs' button at the right of the participants header. Bound to a new MainViewModel.StopAllIsosCommand that snapshots the enabled list, awaits DisableIsoAsync sequentially, and silently swallows per-pipeline failures (best-effort emergency stop). CanExecute gates on whether any ISO is currently enabled.
3. WindowStateStore service persists the main window's Left/Top/Width/Height/State to %LOCALAPPDATA%\\TeamsISO\\window.json on close and restores it on SourceInitialized. Multi-monitor friendly: a saved position with no corner inside any virtual screen is rejected so a disconnected monitor doesn't strand the window off-screen.
4. Two new unit tests cover FrameProcessor's drops + duplicates accounting. 76/76 unit tests pass (was 74).
Six related polish items, all building on tonight's groundwork.
1. App icon: teamsiso.ico generated from dragon-mark.png at 7 sizes (16-256), wired as ApplicationIcon in the WPF csproj, MainWindow.Icon, AboutWindow.Icon, and ARPPRODUCTICON in the WiX MSI. Taskbar / window / Add-Remove-Programs all show the dragon mark now.
2. Running incoming FPS: ring buffer of last 30 frame timestamps in IsoPipeline; ComputeFps() returns moving-average rate. Surfaced on IsoHealthStats.IncomingFps and shown in the Source column of the participants DataGrid as 'WxH · 59.94 fps'. Resets cleanly on every supervisor restart.
3. Drops counter: FrameProcessor.Stats already aggregated FramesDropped (closest-frame strategy when the receiver outpaces the processor) and FramesDuplicated; just plumbed _liveProcessor through IsoPipeline so GetStats() can read them. Exposed in the Live column under the in/out counters as a coral-tinted 'drop N'.
4. Console --version flag: prints engine version (with embedded git SHA), .NET version, OS, NDI runtime banner, expected prefix, exit-code legend, plus a wilddragon.net link. Useful for support tickets.
5. About dialog: chromeless modal with the dragon mark + version / .NET / OS / NDI runtime fields and a link to wilddragon.net. Triggered by clicking the rail logo.
6. Teams launcher Stop toggle: TeamsLauncher gains IsRunning() and StopAll(). The rail's Teams button now toggles — if Teams is up, ask to close all Teams windows via WM_CLOSE; otherwise launch as before. Confirms before stopping so we don't kill the user's call mid-transition.
Tests: 74/74 unit + 9/9 NDI integration green throughout. MSI builds clean and now embeds the dragon icon for ARP.
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).
