Summary

Update GitHub.Copilot.SDK from 1.0.26-preview.0 to the stable 1.0.26 release. This aligns the bundled Copilot CLI runtime to 1.0.103, updates the displayed third-party notice, and keeps the in-process runtime version assertion in sync. The SDK release notes and v1.0.25-to-v1.0.26 source diff were reviewed; the app does not use the removed remote-session API, so no functional migration was needed. The SDK's FFI callback lifetime and request-correlated send/wait improvements are picked up automatically.

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 - passed (0 warnings, 0 errors)
• dotnet test RepoSyncRadar.sln -- --filter-not-trait Category=Manual - executed with the skill-prescribed --timeout 10m before --; 1,579 passed and 2 failed. The failures were TcpPreviewPortAllocatorTests.AllocateSingle_Skips_Listening_Preferred_Port and AllocateComparison_Skips_Pair_When_After_Port_Is_Listening; both are unrelated port-allocation assertions. App.Tests (827), App.E2E.Tests (27), and Integrations.Tests (55) passed.
• Focused tests: N/A - SDK/runtime and notice tests ran in the full solution test suite.
• Manual smoke / screenshots, if UI or WebView behavior changed; otherwise replace with N/A - no UI/WebView changes: N/A - no UI/WebView changes

Risk And Rollback

• User impact: Stable SDK and bundled runtime update; no app workflow changes.
• Operational risk: Low. The in-process runtime bundle and reported runtime version were exercised by automated tests.
• Rollback plan: Revert the package, notice, and runtime assertion version changes together.

Release Notes

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

Release note draft:
