Preview: promote selected layer for hit testing
Temporarily raise the selected preview item and prioritize it in the custom hit test without changing scene order. Refresh integration-test expectations for Brand logo layers and explicit thumbnail assets.

vv webcam Unit 2: the Chat scene in the vertical tier - rect only, tile or one whole 607x540 area
The creator's locked table (2026-10-17) gives the Chat scene its own rules in the 9:16 tier: RECT ONLY - the circle option is not offered - and a size that is either the normal small tile or ENLARGED to fill one whole 607x540 area (top or bottom). Unit 1 shipped the per-scene placement; this unit is the Chat scene's own variant of it. The rule lives on the MODEL, not on the button: - Models/SceneElement.cs: ClipShape and ToggleClipShape() are now virtual. - Models/WebcamSceneConfig.cs: VerticalShapeLocked (set per scene by the VM) OVERRIDES the ClipShape property, so no writer can slip a circle in - the toggle, the Shape button and the placement swap all go through it. The lock is cleared BEFORE the 16:9 layout comes back, so the desktop shape returns. - ViewModels/MainViewModel.Webcam.cs: CanToggleClipShape (the circle is NOT offered in the vertical Chat layout - the Shape button disappears, it is not merely greyed out), IsChatSceneCamera, ResizeWebcamInVerticalTier. - Models/VerticalCameraLayout.cs: FillsArea (the "enlarged" state, derived - no new column) and SizeFor - the Chat camera's TWO sizes, the tile or the whole area, whichever is nearer the requested width, so the resize handle has two detents instead of any size in between. - An enlarged camera FILLS the area its centre is in (top or bottom), so dragging it up/down swaps the areas. - The Chat camera is auto-tiled like the Live one when the vertical tier is picked - otherwise the vertical chat stream has no camera at all. - Controls/PreviewPane.xaml.cs: the resize routes through the VM; the drag assigns, lets the model clamp into the band, then snaps (so the enlarged camera can be dragged from the top area to the bottom one). Test: ytLive.Tests/VerticalChatCameraLayoutTests.cs - the ONE Good Dog test for the unit: the vertical tier is picked -> the Chat camera comes into the band as a small RECT tile -> the circle option is not offered and cannot be set even on the model -> dragged up and enlarged it fills the TOP area exactly -> back to 16:9 the desktop layout is restored exactly and the circle option is offered again. 430/430 tests pass, 0 warnings. Research (the creator's table is the established practice, not our invention): - Streamlabs' vertical guide: "splitting the screen in half horizontally, placing the camera feed in the top half and the main content on the bottom (or vice versa) may be the bet", and a just-chatting vertical wants the camera "to take up most of the screen" (streamlabs.com/content-hub/post/overlays-vertical-and-horizontal-streaming) - Bloopbot's vertical overlay docs describe the same per-layer model we use at scene granularity: "move or resize a layer on Vertical and it stops being Auto-placed. It keeps the place you gave it, and the horizontal layout is not touched" (bloopbot.com/docs/vertical-overlays-twitch-dual-format) - our swap-at-tier-change, stored per scene. - Landmine recorded: "about the bottom 560 px of the vertical video can be covered by Twitch's chat and player controls on phones" (Bloopbot) - the Chat camera's enlarged BOTTOM area may be half-hidden by the platform chrome; TASK 53's safe-zone work decides that. Memory in the same commit: ai.md (the Chat rules, the shape lock, the tests), TASKS.md + TASKS/task-57-vertical-camera-layout.md (TASK 57 complete), HANDOFF.md, MyMistakes.md (3 recipes: lock the model property not the UI button; two detents for a discrete size set; the edit tool cannot match an oldString with an em dash), Models/ViewModels/Controls index rows. |

vv webcam Unit 1: the vertical (9:16) tier keeps its OWN camera placement per scene
The vertical tier is a centred band crop of the SAME 1920x1080 master (band x
656.25, w 607.5, h 1080), so the 16:9 camera placement (x~1408) falls outside the
cropped window and the creator is simply not in the vertical stream. Each scene
now keeps its own vertical position, size and shape; switching back to 16:9
restores the desktop layout exactly (the creator's locked table, 2026-10-17).
Geometry only - NO render-path change. The preview and the compositor both read
the element's own X/Y/W/H + ClipShape, so the tier switch swaps the LIVE geometry:
- Models/VerticalCameraLayout.cs (new): the pure math - the band, its two 607x540
areas, the six spots (top/bottom x left/centre/right), the 32px inset and the
270x152 default tile (480x270 in the 1080x1920 output) in the bottom-right spot,
the corner the 16:9 default webcam uses.
- Models/WebcamSceneConfig.cs: the vertical placement lives in seven additive
columns (VerticalX/Y/Width/Height/ClipShape/RectWidth/RectHeight; NULL = "this
scene has no vertical placement yet"). The 16:9 layout stays in the old columns
and is parked in the transient Landscape* fields while the vertical tier is
live; Begin/EndVerticalLayout + CommitLiveLayoutToVertical do the swap. The
X/Y/W/H overrides clamp every write into the band - outside it the camera is
invisible in the vertical output.
- Models/SceneElement.cs: X/Y/Width/Height became virtual so the derived element
constrains every writer (drag, resize handle, typed fields) in ONE choke point
instead of three writers each re-implementing the rule.
- ViewModels/MainViewModel.Webcam.cs + .Streaming.cs: IsVerticalTier/VerticalBand,
ResolveVerticalCameraLayout(s) (the tier swap), MoveWebcamInVerticalTier /
SnapWebcamInVerticalTier (the six-spot snap, by the tile's centre),
EnsureVerticalCameraLayout; ApplyStreamQuality is the tier-change hook. The
Live scene gets its small tile automatically on the first vertical switch (the
vertical stream would otherwise have no camera at all); the other scenes keep
their 16:9 placement until the creator drags them into the band.
- Controls/PreviewPane.xaml.cs: the drag/resize route through the VM snap under
the vertical tier instead of free-floating over the master.
Controls/LeftPanel.xaml: the webcam properties gained a Geometry section
(X/Y/W/H) for the manual entry the creator asked for, bound to the LIVE
placement, gated on the VM's IsWebcamSelected (NOT SelectedElement.IsWebcam -
the TASK 51 test finds that panel by binding text and would match twice).
- The store: seven guarded ADD COLUMNs, the INSERT/SELECT extended, and the
X/Y/W/H/ClipShape columns stay the 16:9 layout - while the vertical tier is
live the save writes the parked values there and the live ones into Vertical*.
Test: ytLive.Tests/VerticalWebcamLayoutTests.cs - the ONE Good Dog test. The
vertical tier brings the Live camera INTO the band as a small tile; dragging it to
the top-right lands it top-right inside the band; back to 16:9 the desktop layout
is restored exactly (1408/778/480x270); both placements survive a save + reload.
Full suite 429/429, 0 warnings. LayerReorderPersistenceTests.RealMouseDrag fails
ALONE on a clean tree in this environment - pre-existing flake, proven by stashing
this work, not a regression.
Derivative work: OBS has no built-in per-aspect-ratio layout storage - the
maintainers' answer is "create a second scene and add the scene you want to send
as source" (obsproject.com/forum/threads/161307) - and Streamyard's dual-aspect
guide says the same ("no built-in way to store separate layouts per aspect ratio",
so you rely on manual workarounds and plugins):
https://streamyard.com/blog/dual-aspect-ratio-streaming-tool
Our per-scene, per-tier stored placement, resolved on the tier change, is the
step past both.
Memory in the same commit: ai.md (new section), TASKS.md + TASKS/task-57-*.md
(Unit 1 shipped, Unit 2 = the Chat scene still open), HANDOFF.md, MyMistakes.md

webcam-identity rule) and the Models/Services/ViewModels/Controls index rows.

Zoom: anchor the capture, magnify the full composite, draw on top (Unit: zoom rework per creator correction)
Creator corrected the "loupe" zoom on 2026-10-08: the click anchors a fixed
capture region (box/2 centred on the click) and the box is a live 2x view of
that region — dragging the box never changes its content; it magnifies the
fully-composited frame (every layer, incl. webcam) and draws LAST (n+1).
Rectangle shape is 4:3 ("more of a 640x480 aspect").
- MainViewModel.Zoom.cs rewritten: ActivateZoom anchors CaptureX/CaptureY
(independently clamped); UpdateZoomMove relocates the box only; the per-frame
BuildZoomFrame/ZoomFrameBuilder path is gone.
- SceneCompositor: skips the active ZoomSceneElement in every layer loop and
BlitZooms it last via the new pure ZoomMagnifier (2x bilinear, temp snapshot
via ArrayPool, round clip).
- Preview: ZoomBox hoisted above CanvasGrid as a sibling; its brush samples the
whole composed preview at the fixed capture (2x).
- Tests: ZoomMagnifierTests (box-over-blue shows green capture at 2x incl. an
extra red "layer" — the loupe/backdrop-only regressions both fail it) +
round-clip; ZoomBoxInteractionTests rewritten (anchored capture, move-doesn't-
change-capture, 4:3/9:16/square). 404 pass, 2 known environment flakes.

Zoom: compose the box as a real 2x layer above the background (Unit: zoom layer + magnification proof)
Right-click now creates a transient ZoomSceneElement at z-index 1 whose pixels are a genuine 2x magnified sample of the backdrop (live capture under art), composited into stream/recording like any layer while the output crop stays the tier. All shapes are centered on the click and clamped to frame; healed on load/scene-create, never persisted, hidden from the layers list + element template (IsZoomLayer). BuildCompositorOptions is now internal = always tier crop (test seam). ZoomFrameBuilder is a pure static sampler (box/2 window centered on the box center, single-slot cache) proven by a banded-backdrop test; LayerReorderPersistenceTests drag resolves rows by item since the collapsed zoom row shifts container indices. Also books TASK 51 (webcam background Remove + Blur) and syncs memory docs (HANDOFF, MyMistakes, indexes). Full suite: 405 passed, 0 warnings. |

Zoom: fix preview zoom box + shape-aspect anchoring (Unit: zoom box visuals)
Right-click in the live preview now procs a box that is actually visible and populated with the zoomed region, and each Zoom View Shape sculpts the box per spec. OBS-style derivative: magnifier box shows the composited region and dims the surroundings (same pattern as OBS "zoom" / preview region highlights). Root causes of the invisible box (two WPF traps, recorded in MyMistakes.md): - Empty <VisualBrush Stretch="None"/> used as an OpacityMask paints nothing, so the mask alpha is 0 and the WHOLE box (border included) went transparent. - ZoomBox lived inside CanvasGrid while its VisualBrush sampled CanvasGrid — a circular reference WPF renders as nothing. Hoisted ZoomBox to a sibling of CanvasGrid inside a new PreviewCanvas wrapper (same 1920x1080 space). Shape semantics (MainViewModel.ActivateZoom): - Circle: square, click point = center. - VerticalRectangle (phone): tall 9:16, click point = top-left corner. - HorizontalRectangle (tablet): wide 16:9, click point = top-left corner. - Boxes stay fully inside 1920x1080 via Math.Clamp. UI: ZoomRectOutline/ZoomCircleOutline shapes replace the square Border; circle clips the box to an EllipseGeometry; brush Visual released when inactive. Zoom View Shape dropdown now uses the standard YtComboBox style. Test (Good Dog rule, one integration test): ZoomBoxInteractionTests verifies aspect/anchoring/clamp per shape and the matching outline+clip in the real MainWindow. Full suite 404 passed, 0 warnings. Memory: HANDOFF.md zoom state updated; WPF VisualBrush traps appended to MyMistakes.md. |

refactor: extract PreviewPane out of MainWindow.xaml — Phase 2, Commit 15
PreviewPane.xaml(.cs) takes the center preview (Row 1 Col 1): the 1920x1080
canvas (OverlayCanvas/SelectionOverlay/BrandFlashLayer/SocialBarElement),
the text pull-out drawer, and the live-controls row (TRAX / game / mic meters,
volume sliders, speaker toggles, socials button) inside the preserved
glow/background Border.
Code-behind moved into the control (drive by DataContext==MainViewModel):
preview drag/select/resize/hit-test (Preview_Mouse{Down,Move,Up},
EndPreviewDrag, HitHandle, HitElement), webcam context-menu handlers
(WebcamMenu_ChangeWebcam/SetBorderAnimation/StopBorderAnimation/
FindBorderShape/CreateBorderAnimation/AddDoubleAnimation/SetBorderColor/
HideInScene/Remove), social-bar glow (SocialBar_MouseLeftButtonDown,
SocialsButton_Mouse{Enter,Leave}, SocialGlowTick), audio controls
(VolumeSlider_*, GameVolumeSlider_*, MicSpeaker_*, GameSpeaker_*,
SetSliderValueFromClick, FindParent), and TraxButton_*.
Window keeps the left source/property/chat panel + thumbnail strip + overlay
host, and routes the selection overlay and preview hit-testing through the
control's public surface (_previewPane.UpdateSelectionOverlay(bool),
IsClickInsidePreview/Drawer, PreviewPane.IsDraggableElement). BackgroundMenu_*
stayed in the window because the left-panel source context menu uses them
(the preview's own desktop/refresh menu binds RefreshCaptureCommand instead).
Preserved the outer preview Border (background/glow/margin) that was initially
dropped in the cut — caught and restored before commit. Pruned now-unused usings
(System.Net.Http, Media.Effects, Media.Animation, Media.Imaging, Shapes,
Threading) from MainWindow.xaml.cs.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in the same commit.
