**Verifying workload map usage and code consistency**

I’m double-checking that `combinedWorkloads` streams correctly, using `GetValueOrDefault` safely on the dictionary, making sure `totalHistoricalWorkload` is properly handled or removed, and verifying no duplication in fairness logic. I’m also ensuring null checks and early returns work as expected when personnel or workloads are empty, and considering if running `dotnet format` might help maintain code style before updating the plan status.

**Clarifying string escaping in PowerShell**

I'm figuring out how to correctly include double quotes inside a string assignment in PowerShell. The current use of single quotes with escaped double quotes is treated literally, so I need to switch to double quotes with proper escaping or use a here-string to get the desired line formatting. I'll try assigning the line with a here-string to avoid confusion around escapes.

**Planning targeted file revert and reapply**

I see the overall diff is overwhelmed by whitespace changes caused by trimming, which makes the changes hard to review. To fix this, I’m going to revert the entire file back to HEAD and then carefully reapply only the intended fairness-related modifications. This way, I can avoid noisy trailing space changes and keep the diff clean and focused on meaningful edits. It will be a bit manual but manageable given I know exactly which sections to update.
