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 work (2026-08-28) — CURRENT MODEL: canvas-size viewport + content crop

Root cause finally isolated: hosting the page at the ELEMENT-box size clips full-bleed widgets (designed for ~1920×1080) to their upper-left chunk inside a small viewport — "image truncated to the upper-left corner regardless of scaling." That truncation persisted across every earlier model because all of them rendered the page at the box (or a mix); e917c41's full 1920×1080 render was the only one that showed full content, and its letterbox dead space was purely the display Uniform + the box aspect mismatch — not the render.

The model (implemented, visual verification pending):

• Services/WebView2Manager.cs — page renders at the MASTER CANVAS size (1920×1080), stable, never tracked: full-bleed widgets render FULL (no upper-left truncation); dragging the box never reflows the page; overflow:hidden (html+body) + transparent-bg injection. After each nav QueryContentBoundsAsync reads the page's real content rect (scrollWidth/scrollHeight vs innerWidth/innerHeight) and CaptureFrame crops to the actual content bounds anchored at (0,0). Immediate capture on NavigationCompleted.
• MainWindow.xaml — web <Image> Stretch="Fill": the cropped 1920×1080 frame maps flush under the box (Box == widget bounds at every size, pinned (0,0), no dead space).
• Invariants: render at canvas size; crop to content; Fill to box.

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 4/4. 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).

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's verdict on viewport==box (geometry-agnostic) rendering — visual check with a widget URL at several box sizes; the selection frame must snap flush with no padding.
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.
