💡 Motivation and Context

The release job failed because BackgroundFlushContinuesAfterException waited only one second for its second background flush. The same commit passed in the regular CI workflow.

The test now uses explicit task signals instead of timed waits. It holds the first flush until the next batch is queued, then lets that flush throw and checks that the next batch is delivered. It also watches the background tasks so a worker that exits after the exception fails an assertion instead of leaving the test waiting forever. Production code is unchanged.

💚 How did you test it?

• dotnet restore --locked-mode, bin/fmt --check, and the Release build passed after syncing with main.
• The full test suite passed with dotnet test --configuration Release --no-build --nologo -- RunConfiguration.TargetPlatform=ARM64: 2,883 passed and four existing skips. Both test targets rolled forward to the installed .NET 9 runtime on this Mac.
• The updated test passed 20 repeated runs on each target before the sync.
• Temporarily made the background worker exit after an exception. The updated test failed on both targets without a timeout. Reverted that mutation.
• Autoreview reported no actionable findings.

📝 Checklist

• All commits are signed (see Commit signing)
• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran pnpm changeset to generate a changeset file

This is a test-only change. No changeset or documentation update is needed.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Pi used shell, file editing, GitHub CLI, and autoreview tools to investigate the failure and update the test in a dedicated worktree. Explicit synchronization was chosen instead of increasing the timeout. The regression check confirmed that the test still detects a worker stopping after a flush exception. Human review is required.
