HANDOFF — Session State

Branch / Commit State

main, working tree clean. Web-source bounding work is DONE, verified, committed, and PUSHED (2026-08-28) — the first push in a while; the web feature is complete and on origin. No feature branches pre-1.0: all work lands on main per work unit.

The web-source rendering work (2026-08-28) — DONE: canvas-size viewport + ALPHA-BBOX crop

VERDICT (creator, 2026-08-28): bounding is PERFECT. Verified with a second widget resource that has no glow effect. The earlier "remaining defect / dead-space gap" was the WIDGET'S OWN GLOW effect pushing out its perceived borders — NOT a code bug. The alpha-bbox was already hugging the glow halo; with a plain widget the dashed selection border sits exactly on the widget edge.

History of failures (log wiped from MyMistakes.md per task-complete rule; see git history): box-size rendering clipped full-bleed widgets to their upper-left chunk; JSON.stringify return double-encoded under ExecuteScriptAsync (crop silently disabled); scrollWidth/scrollHeight at canvas size = whole viewport for full-canvas wrappers (no trim); DOM-element-union measured an unsettled layout on NavigationCompleted (BROKE the image); sizing the container to the crop (ab29ec8) made things worse (reverted).

The model that shipped:

• Services/WebView2Manager.cs — page renders at 1920×1080 (stable, never tracked); overflow:hidden
  • transparent-bg injection. FindContentBounds scans the Bgra32 capture per frame and crops to the bounding box of NON-TRANSPARENT pixels — the widget's true rendered extent, measured from the frame itself. No DOM query, no layout timing: it can never truncate visible content (worst case = full frame = the confirmed-good image). Stretch="Fill" maps the cropped frame flush under the selection box → the box hugs the widget on all four sides. QueryContentBoundsAsync + the JS script are DELETED.
• MainWindow.xaml — web <Image> Stretch set to Fill via the IsWebSource DataTrigger (unchanged).
• Invariant: render at canvas size; crop to the alpha extent; Fill to the box.
• Unit tests: 7/7 (3 FindContentBounds, 4 control-size.)

Property panel / sliders (2026-08-28): web URI ✕ clears the textbox; web ✓/✕ icon buttons IsTabStop="False" so Tab walks X→Y→W→H→URI; Slider style IsMoveToPointEnabled="True" restores click-anywhere-on-bar. All three confirmed fixed by the creator.

Build: 0 warnings; tests 7/7 (WebView2Manager). Rejected for the record: box-sized viewport (upper-left truncation), fixed 1920×1080 + Uniform (letterbox dead space), CSS margin/100% reset (enlarged gap), viewport==box (reflow/truncation/scrollbars), DOM-union crop (broke the image), container==content auto-fit sized to the crop (ab29ec8, reverted).

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. Done (2026-08-28): web-source bounding verified PERFECT and pushed. If an animated widget causes visible crop jitter later, add hysteresis as a follow-up — not queued.
2. Graceful handling of navigation errors / invalid URIs (TASK 17 ×9) — only if the creator asks.
3. Continue queue: TASK 18 local recording, TASK 21 media source, TASK 22 audio sync offset.
