The creator's profile still showed the previous Starting art after the replacement, with
`Art.DefaultVersion = 4` recorded — so the version gate had already declared itself done. It
compared a constant against the embedded resource, and those two were compiled at different
moments (version 4 landed with the OLD image embedded; the corrected image reached the assembly
one build later). A version bump can always be raced that way.
The seed now compares BYTES: `LayoutStore.AssetMatches` hashes the bundled resource and checks the
row the background already points at. Same bytes → leave it untouched (so this is idempotent and
never churns the database). Different bytes → re-stamp. The version constant and its setting are
gone, because a heal that only runs once can silently skip the one launch it was needed for.
`SceneThumbnailTests` planted its own art on a background still flagged as default art — in the
real app that state only ever means stale bundled art, because Browse… sets the path and clears
the flag. The fixture now models a creator's own picture.
Tests: 572 green, 0 warnings. Verified the profile's Starting asset hash (167CDD3B…, the
two-category render) differs from the shipped `starting-background.jpg` (5FC6DD22…), so the next
launch re-seeds it.
LayoutStore.cs 1402 -> 47-line shell + 5 partials, grouped by functionality
(line count is a consequence, not the goal):
- LayoutStore.Migrations.cs: all DB schema migration (EnsureSchema, GetUserVersion,
MigrateSourceTable/WebcamConfigTable/ToV3/SceneTable/SceneSocialBarColumn/
SocialsTable/SocialEntryTable)
- LayoutStore.Load.cs: Load() scene/source read-back
- LayoutStore.Save.cs: Save() full scene tree write
- LayoutStore.Settings.cs: key/value settings + mic/record-folder/reusable-stream
+ license/transition/broadcast/hotkey/window-state GetSetting/UpsertSetting
- LayoutStore.Assets.cs: GetAssetBytes/UpsertAsset blob IO
- LayoutStore.cs: shell — Instance, fields, ctor, Dispose
Converted to public partial class LayoutStore : IDisposable. Pruned per-file
dead usings. Phase 3 DOWN: no production .cs exceeds 500 lines.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 3 tracker updated in same commit.
