What changed in this PR

Updates the CodeCoverage and AffectedTests dependencies used by TestFx to upstream build 20261021.4.

Changes:

Advances both packages from 18.13.0-preview.26519.2 to 18.13.0-preview.26521.4.
Updates dependency provenance to commit a15070b339d58b217540acab00b14cd1645c23a6.

Test-value evidence: The supplied version declarations match the PR metadata. Integration results for these package versions were unavailable.

File	Description
`eng/Versions.props`	Updates both package version properties.
`eng/Version.Details.xml`	Records matching package versions and upstream commit hashes.

Correct CI distinction between node reuse and MSBuild multithreading

eng/common/build.sh:88

Only node reuse defaults off on CI; eng/common/tools.sh:56–65 still defaults msbuild_multi_threaded to true, so this wording incorrectly implies that CI disables MSBuild's -mt mode. Restore the distinction between the two defaults in Arcade and re-sync this mirrored file.

🔍 Build Failure Analysis

Summary — all four build legs fail in Restore because the flowed 18.13.0-preview.26524.1 Microsoft.Testing.Extensions packages are not available on any configured feed.

Root cause: dependency flow references an unavailable package build

The PR updates both CodeCoverage and AffectedTests to 18.13.0-preview.26524.1. Restore cannot find that version for Microsoft.Testing.Extensions.AffectedTests, Microsoft.Testing.Extensions.AffectedTests.Storage.AzureDevOps, or Microsoft.Testing.Extensions.CodeCoverage; the test-tools feed reports 18.13.0-preview.26523.4 as the nearest version, and the other configured feeds report no matching package.

This produces 139 NU1102 errors across the Linux Release, Windows Debug, Windows Release, and Windows application-model acceptance legs. The errors are repeated across consuming test projects, but they all have the same package-publication/version-pin cause.

Proposed fix

Ensure the 18.13.0-preview.26524.1 build publishes all three packages to the configured test-tools feed, then rerun this PR. If that build will not be published, regenerate or revert the dependency flow to a coherent available build; update both eng/Versions.props and the matching version/SHA entries in eng/Version.Details.xml together. I did not emit an inline suggestion because changing only the package-version lines would leave Darc dependency metadata inconsistent, and the binlogs cannot establish the source SHA for an alternative build.

Build overview

Leg	Result	Projects	Errors	Failed target/project
Linux Release	Failed	56	27	`Restore` / `NonWindowsTests.slnf`
Windows Debug	Failed	74	56	`Restore` / `TestFx.slnx`
Windows Release	Failed	74	56	`Restore` / `TestFx.slnx`
Windows application-model acceptance	Failed	25	4	`Restore` / `MSTest.Acceptance.IntegrationTests.csproj`

The per-leg totals include one terminal Build failed. record; all 139 coded errors are NU1102 restore failures.

Final test-triage resolution — Azure Pipelines build 1648234

Analysis is final for check microsoft.testfx. No test-failure signal was found, so no issue is warranted.

The collector found 0 failed or retried test results, 0 slow-test candidates and 0 crash or hang diagnostics. Evidence collection was complete (no fetch failures or skipped reports).
The build failed because of Build task failures. They occurred in the Windows Debug, Windows Release and Linux Release legs. A Build UWP and package-contract acceptance tests task also failed, in the Windows application-model acceptance leg.
These are build or compilation failures, not test failures. Build Failure Analysis owns them, and this analysis does not diagnose their cause.

Confidence: high that there is no test-level failure to triage. Test results are absent because the build failed before tests ran, so this is not evidence that the tests are healthy.

Next step: fix the build errors reported by Build Failure Analysis, then re-run so the tests execute.
