 ## Copilot Workflow
 
+- **PII scan before committing**: Before staging or creating any local `git commit`, run the repository's PII scanner (`pwsh .scripts/Find-Pii.ps1`, or `-FailOnFind` as a hard gate) and remind the user to do the same. It seeds real values from the gitignored Local config files and flags any that have leaked into tracked files or history. Never commit if high-confidence (seed) PII is reported. The generated `pii-report*.csv` is gitignored and must never be committed.
 - **Test execution**: Never run tests automatically — they may be integration tests requiring extra setup. Always prompt (ideally with a visual yes/no button) before running any tests.
 - **Preserve git history during renames/moves**: When renaming or relocating files, first perform the rename/move (preferably via `git mv`), then make content edits to the file in its new location/name. This two-step approach preserves git history across the rename. Do not delete-and-recreate files when a rename or move is the intent.
 - **Build after refactoring**: After any refactoring, build the **entire solution** (not just the affected project) to catch edge-case compilation errors in dependent projects. When multiple `.sln` / `.slnx` files exist, prefer the one with a `.Debug.slnx` suffix.
