HANDOFF — 2026-11-02 (test failure follow-up)

State

main; Logs tabs committed as 9fa06c6, local and not pushed.
ChannelStatsServiceTests uses dates relative to UTC so its 90-day upload assertion does not expire with the calendar; fix committed as 3985a41.
ScoreboardPropertiesTests now checks for the themed PropertyPillCheck style instead of stale YtCheckBox markup; committed as 221b816.
PropertiesHierarchyTests now checks shared styles and scopes the duplicate shape bindings to the Shape block; committed as 91e308e.
GeometryFieldWidthTests now identifies the shared draggable-layer Geometry block; committed as 82609a5.
NotificationServiceTests runs tint assertions with real theme resources and uses the current Brush.ErrorContainer token; committed as caf91e6.
ScoreboardSimulationTests now checks the shared Helpers/DevBuild.cs compile-time gate; focused test passes. This task is ready to commit.
Clean app build is 0 warnings. Full suite: 4 failed / 518 passed of 522; remaining failures are being handled one task and one local commit at a time.

Commit the scoreboard-simulation guard update, then take the next remaining failure. Do not push absent a milestone/checkpoint request.

Build/test with Windows dotnet.exe; the full suite can hang in WASAPI teardown.
verify.sh cannot pass until the remaining 4 suite failures are resolved; scope checks are run separately when that gate exits early.
Any integration test constructing MainWindow must set LayoutPathOverride to a temporary DB and clear it in finally.
Bundled FFmpeg stays outside the single-file exe (ExcludeFromSingleFile="true").
