Models — index

Plain data types. No logic beyond what a property can carry. See schema.md for the memory-map conventions.

File	Purpose
Scene.cs	A scene: Name, IsHidden, IsChatScene, IsEditing, HasBackdrop (Live-only policy flag, default off — only the canonical Live scene has one, see SceneCatalog), Elements collection (images + webcam config), WebcamConfig accessor
SceneCatalog.cs	The five canonical scenes (Starting/Live/BRB/Chat/Ending) — the product, by name: All, IsCanonical, Is(name, canonical) (case-insensitive trim), IsChat, HasBackdrop(name) (true only for Live). Drives the empty-DB seed, the "+" missing-scenes menu, and MainViewModel.EnforceBackdropPolicy
Source.cs	A source: SourceType enum (DisplayCapture/WindowCapture/Background/Image/TextOverlay/ChatBox/Countdown/WebSource/MediaSource/AlertBox (TASK 43 — the celebration zone, one per layout) — Webcam removed), X/Y/Width/Height, Opacity, IsEnabled, ImageSource (static) / VideoImageSource (live frames), DisplaySource (IsLiveCapture → video, else static), ClipShape enum (Traditional/Round), IsMirrored + MirrorScale, MirrorButtonText/ShapeButtonText, asset identity, IsImageSource (XAML binds this, never Type), backdrop surface: IsBackdrop (permanent bottom layer, never removable), CaptureKey (persisted monitor:<n>/window:<hwnd>/picker:<name>), IsLiveCapture (Type is Display/WindowCapture)
SceneElement.cs	Base for anything placeable in a scene: shared layout/clip/mirror/border surface, virtual IsWebcam/virtual IsImageSource/virtual IsZoomLayer (TASK 52); ToggleClipShape + persisted RectWidth/RectHeight (pre-Round rect so round→rect restores after reload)
ZoomSceneElement.cs	Transient zoom box (TASK 52, creator-corrected 2026-10-08): carries the box rect AND the anchored CaptureX/CaptureY (the fixed box/2 capture window set on ActivateZoom; moving the box never touches it). IsZoomActive flips Kind Static→Dynamic (leaves the baked base while active); never persisted (LayoutStore save skips non-Source/non-WebcamSceneConfig rows), never shown in the layers list or the element template (IsZoomLayer gates both). The compositor SKIPS the active element in every layer loop and draws its 2x content LAST (layer n+1) via ZoomMagnifier.
Webcam.cs	Singleton webcam identity: Id, DeviceId, Name (one row app-wide)
BackgroundEffect.cs	TASK 51: per-webcam background effect enum None / Remove / Blur, carried by WebcamSceneConfig
WebcamSceneConfig.cs	Per-scene webcam placement (subclass of SceneElement): geometry + IsVisible + border (BorderColor/BorderOpacity/BorderWidth/BorderAnimation) + VideoImageSource; WebcamId links to Webcam; TASK 51: BackgroundEffect + BackgroundStrength (0..1, default 0.5) + the radio-pill surface RemoveBackground/BlurBackground (one on turns the other off; both off = None)
QualityOption.cs	Resolution tier record (Display, Fps, Bitrate, Width, Height); Label formats as 1080p60 (8Mbps) — drives the bottom-bar dropdown and the output-rect math
StreamConfig.cs	StreamConfig (note: TargetBitrate/Resolution defaults are stale — not yet wired to the dropdown), StreamHealth (bitrate/FPS/dropped/duration), StreamStatus enum
MicStatus.cs	Footer mic indicator: NotConnected / Connected / Problem — the state behind the MIC button's status dot (red = no device/capture off, green = capturing, yellow = a requested mic failed: in use/unplugged)
YouTube.cs	YouTubeChannel and ChatMessage (chat feed) — since TASK 43 every message carries Kind (ChatEventKind None/SuperChat/SuperSticker/NewMember/MemberGift/GiftReceived/MemberMilestone) + event payload fields (SuperChatDisplayString, SuperStickerDescription, GiftNewMembersCount, GifterName, MilestoneMonths)
Socials.cs	Social bar (global layer, never a Source): SocialService enum (YouTube/Twitch/X/Instagram/TikTok/Facebook/Discord/Kick/Threads/Bluesky/GitHub/LinkedIn/Pinterest/Snapchat/Reddit/WhatsApp/Telegram/Link/Website/Fediverse), SocialEntry (Service/Handle/ProfileUrl/FediverseSoftware), SocialsConfig (Entries + BarPosition Top/Bottom + BarEnabled on/off — BarJustify dropped, column back-compat), SocialServiceIcons (canonical URL builder + DetectService (URL domain / fediverse @user@domain → Fediverse / bare→Website) + bundled SVG logo path data per service (LogoDataFor) + LogoDataForFediverse(software) mapping nodeinfo software names (mastodon/peertube/pixelfed/misskey/lemmy/pleroma/firefish) to logos with a generic fediverse glyph fallback (FediverseIconData) + LockedIconData/DoNotIconData — initials/colors gone)
