HANDOFF — Session State

Branch / Commit State

main, dirty working tree being committed as one unit (web source rendering fix — user-confirmed working). NOT pushed — user rule: never push without explicit instruction (2026-08-24). No feature branches pre-1.0: all work lands on main per work unit.

The web-source rendering fix (2026-08-28) — USER-CONFIRMED WORKING

The bug: preloaded web resources rendered truncated (upper-left only) and misbehaved as the box resized. The WebView2 control was being resized to the element box as it changed.

The fix — one idea, three-line change, the OBS/CEF pattern:

• Services/WebView2Manager.cs — viewport is FIXED at the master canvas size (1920×1080), never tracks the box. Control lives off-screen at (-5000,-5000). Page renders full at its designed size; the preview scales the captured frame independently via <Image Stretch="Uniform">. This is what OBS obs-browser does (fixed-viewport texture + independent scene-item scale). Removed the PropertyChanged resize hook. Added an immediate CaptureFrame on NavigationCompleted so content appears instantly on load (was waiting for the next 100ms tick).
• ViewModels/MainViewModel.cs — InitWebView2 now calls RegisterLoadedWebSources() itself; before, registration only happened when LoadLayout ran after manager init, so preloaded sources never registered at startup.
• MainWindow.xaml — scene-element <Image> had a LOCAL Stretch="UniformToFill" that outranked the Style DataTrigger (WPF precedence). Removed the local attribute; Style default is UniformToFill; IsWebSource trigger overrides to Stretch="Uniform" (no crop/truncation).
• ytLive.Tests/WebView2ManagerTests.cs — 3 scale-sync tests tested the removed behavior; replaced with 2 tests asserting the fixed 1920×1080 viewport and that it does not track source dimensions.

Build: 0 warnings, 0 errors. User verified it renders correctly.

Key facts / landmines

• App running locks ytLive.exe → build fails MSB3027 until creator exits the app.
• Startup diagnostics: unhandled exceptions + checkpoints go to %APPDATA%\ytLlive\startup.log (Helpers/AppLog.cs). On a silent startup crash, read that.
• Pre-existing test failures (unrelated to web source, do not chase): AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback + RoundClipInteractionTests.Round_Clip_Corner_Is_Grabbable_And_Shape_Is_Circle.
• Real-MainWindow tests MUST set LayoutPathOverride — DB pollution wiped real data once.
• Good Dog Rule: ONE integration test per change; no new feature branches pre-1.0.
• Scope Lock: declare the file list, run scripts/scope-check.sh before every commit.
• Every feature change ships memory updates in the SAME commit — TASKS.md status + this file.
• No CODING.md; conventions live in AGENTS.md + ai.md.

Next steps

1. Await creator comments on the committed rendering fix; address what he raises; also testing the box-vs-content padding fix (CSS reset + (0,0) anchor) just committed.
2. Follow-up only if the creator asks: graceful handling of navigation errors / invalid URIs (TASK 17 ×9).
3. Continue queue: TASK 18 local recording, TASK 21 media source, TASK 22 audio sync offset.
