Summary

• Update GitHub.Copilot.SDK from 1.0.27-preview.3 to 1.0.27, including the third-party notice and runtime version assertion.
• The exact package bundles Copilot runtime 1.0.104; the release notes instead mention 1.0.104-3. The runtime status and native library hash tests confirm the packaged version and payload.
• Compared the release, preview-to-release source and tests, and exact-package metadata, targets and XML documentation. The package references runtime repository commit 9301f9874504241ceb199febd252b7411a92bd52; the SDK release tag resolves to bf3a9111707c47579d20a5524d03cde85a35d161.
• The only .NET public API addition in this comparison is SessionQuotaPlanTier.Access. The app does not use quota plan tiers, so no additional integration is needed. Runtime-internal improvements are included automatically, but their effects were not independently established.

Scope

• App UI / workflow
• Core services / data model
• Copilot SDK / agent behavior
• Preview / WebView2
• Documentation / release readiness
• Tests / tooling
• Other:

Validation

• dotnet build RepoSyncRadar.sln -warnaserror --no-restore - passed with 0 warnings and 0 errors after restore with a temporary mapped source.
• N/A - dotnet test RepoSyncRadar.sln --timeout 10m --no-restore --no-build -- --filter-not-trait Category=Manual failed: 1,582 passed and 2 unrelated TcpPreviewPortAllocatorTests failed to detect a listening port. Both failures also reproduced in a focused run.
• Focused tests: dotnet test tests\RepoSyncRadar.App.Tests\RepoSyncRadar.App.Tests.csproj --no-restore --no-build -- --filter-class RepoSyncRadar.App.Tests.Copilot.CopilotInProcessRuntimeTests - 16 passed, including runtime status, native hash, and policy schema checks; dotnet test tests\RepoSyncRadar.App.Tests\RepoSyncRadar.App.Tests.csproj --no-restore --no-build -- --filter-class RepoSyncRadar.App.Tests.Components.ThirdPartyNoticesPanelTests - 1 passed.
• N/A - manual smoke / screenshots not run; the only UI change is the third-party SDK version text, covered by the focused component test.

The configured proxy did not yet provide 1.0.27, so restore used a temporary source containing the official NuGet CDN package after SHA-512 verification, with other dependencies mapped to the existing proxy.

Risk And Rollback

• User impact: SDK and its bundled native runtime are updated; the displayed license version reflects the installed package.
• Operational risk: The updated runtime may change behavior; native runtime, policy, and application tests passed, while the two unrelated port allocator tests remain failing in this environment.
• Rollback plan: Revert this PR to restore SDK 1.0.27-preview.3 and its runtime assertion.

Release Notes

• User-facing change
• Internal-only change
• No release note needed

Release note draft: Updated the GitHub Copilot SDK and bundled runtime.

🔵 Needs a closer look

Focused tests reportedly pass, but installed-package startup and model-turn validation remain unconfirmed for the native runtime update.
