Bug: tracked-csproj-bak-files-carry-stale-project-content

[drmoisan]

• Work Mode: minor-audit

Summary

Eight *.csproj.bak backup files are tracked in git on main. They carry superseded project content: two still contain the altcover import that #929 removed from the live project file. They confuse repository-wide searches and consistency checks, and they are stale copies of build configuration.

Environment

• OS/version: n/a
• Python version: n/a
• Command/flags used: git ls-tree -r --name-only origin/main
• Data source or fixture: repository tree

Steps to Reproduce

1. git ls-tree -r --name-only origin/main | grep "\.csproj\.bak$" lists:
   • QuickFiler.Test/QuickFiler.Test.csproj.bak
   • QuickFiler/QuickFiler.csproj.bak
   • Tags/Tags.csproj.bak
   • TaskTree/TaskTree.csproj.bak
   • TaskVisualization.Test/TaskVisualization.Test.csproj.bak
   • TaskVisualization/TaskVisualization.csproj.bak
   • ToDoModel.Test/ToDoModel.Test.csproj.bak
   • ToDoModel/ToDoModel.csproj.bak
2. git grep -l -i altcover origin/main -- "*.csproj.bak" matches QuickFiler.Test.csproj.bak and QuickFiler.csproj.bak.

Expected Behavior

Backup copies of project files are not tracked, and .gitignore excludes *.bak.

Actual Behavior

Eight backups are tracked, and two contain tokens that the live project files no longer have.

Logs / Screenshots

• Attached minimal logs or screenshot
• Snippet: reported as a follow-up by Bug: package-manifest-consistency-residuals #929 (PR fix(929): remove altcover imports, correct SVGControl binding redirects, pass client-id to the repair workflow token step #949).

Impact / Severity

• Blocker
• High
• Medium
• Low

Restoring sections dropped by the promotion tooling.

Suspected Cause / Notes

Probably Visual Studio or NuGet migration backups that were committed by accident. Confirm that no build step or script reads them before deleting them. QuickFiler.Test.csproj.bak and QuickFiler.csproj.bak still contain the altcover import that #929 removed from the live project file.

Proposed Fix / Validation Ideas

• Delete the eight files, and add *.csproj.bak (or *.bak) to .gitignore.
• Optionally extend the Bug: evidence-and-identity-hygiene-sweep #927 repository hygiene guard to flag tracked backup files, with a negative control.
