Conversation
The NuGet.Client-Official "Publish Using Darc" stage fails installing the darc CLI: "The --add-source option cannot be combined with package source mapping." This began on 2026-06-18 when #7453 bumped global.json to SDK 10.0.300, which now rejects 'dotnet tool install --add-source' when <packageSourceMapping> is configured. eng/common is VMR-managed; the fix exists upstream (dotnet/arcade#16642) and already flowed to release/7.6.x via #7437, but dev's VMR backflow is behind. Manually port #7437's eng/common changes (excluding vmr-sync.yml, which has diverged on dev): - darc-init.ps1 / darc-init.sh: --add-source -> --source - post-build/redact-logs.ps1: --add-source -> --source - core-templates/steps/source-index-stage1-publish.yml: --add-source -> --source - core-templates/steps/publish-logs.yml: drop deprecated symbol-server PATs Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Description
Symptom
The
NuGet.Client-Officialbuild's Publish Using Darc stage has been failing since 2026-06-18:The "darc.exe is not recognized" error is a symptom — the real failure is the
dotnet tool install ... --add-sourceline just above it failing, so darc never installs.Root cause
NuGet.Confighas long used<packageSourceMapping>.eng/commontool-install scripts usedotnet tool install --add-source.global.jsontools.dotnetfrom10.0.100→10.0.300. SDK 10.0.300 now rejects--add-sourcewhen package source mapping is configured (Reject --add-source when package source mapping is enabled dotnet/sdk#52863); 10.0.100 allowed it. The last green build used 10.0.100; the first red build used 10.0.300 with the identical command.Fix
eng/commonis VMR-managed. The fix already exists upstream (dotnet/arcade#16642,--add-source→--source) and flowed torelease/7.6.xvia backflow PR #7437, butdev's VMR backflow is behind. This PR manually ports #7437'seng/commonchanges todev:eng/common/darc-init.ps1/darc-init.sh—--add-source→--sourceeng/common/post-build/redact-logs.ps1—--add-source→--sourceeng/common/core-templates/steps/source-index-stage1-publish.yml—--add-source→--sourceeng/common/core-templates/steps/publish-logs.yml— drop deprecated symbol-server PATs--sourceoverrides the source list (compatible with package source mapping) instead of appending an unmapped feed. The next VMR backflow will carry the identical change, so this won't conflict.vmr-sync.yml(also changed by #7437) was intentionally excluded — dev's version has diverged from release/7.6.x (it contains additional VMR-sha-checkout steps) and it's unrelated to this fix.PR Checklist
