The container tracks the element's own Width/Height again; the crop stays in the bitmap.

# 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 + ALPHA-BBOX crop
|
||
|
||
**History of failures (see MyMistakes.md for the full log):** box-size rendering clipped full-bleed
|
||
widgets to their upper-left chunk (fixed — page renders at the master canvas 1920×1080, stable, the
|
||
one render the creator confirmed solid). Then four crop attempts failed in different ways: (1) the
|
||
`JSON.stringify` return double-encoded under `ExecuteScriptAsync`, silently disabling the crop;
|
||
(2) `scrollWidth/scrollHeight` at canvas size returns the whole viewport for full-canvas wrapper
|
||
bodies → no trim (ghost boundary); (3) union-of-DOM-elements measured an unsettled layout on
|
||
NavigationCompleted and BROKE the image (creator's "don't break the rendering" boundary crossed).
|
||
(4) Reverting to f39ebd9's scroll-crop was another dead end (#2 again).
|
||
|
||
**The CURRENT MODEL (this commit):**
|
||
- `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: 3 new for `FindContentBounds` (tight box, no-alpha no-crop, full-alpha no-crop).
|
||
|
||
**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).
|
||
|
||
## 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 the ALPHA-BBOX crop — reload a widget URL at several box sizes; the
|
||
selection frame must snap flush to the widget with no dead space, image must stay identical for
|
||
full-bleed widgets. If an animated widget causes visible jitter, add crop hysteresis as a follow-up.
|
||
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. |
