**Switching to PowerShell script file approach**

I'm seeing that passing scripts with braces and quotes directly to `pwsh -Command` is tricky due to escaping problems. To avoid these quoting issues, I'm planning to write the PowerShell commands to a temporary `.ps1` file using `Set-Content`, then execute that file with `pwsh -File`. This should simplify running the script without dealing with complex escaping.

**Adjusting regex replacement with options**

I'm fixing the regex replacement by adding Singleline mode so dot matches newlines, ensuring the pattern includes both `#region` and `#endregion` to preserve sections properly. I’m also checking that special characters and escaping are handled correctly, and pondering why the previous attempt failed silently—likely an uncaught exception in the function call—so I’ll try again with these fixes.

**Planning systematic patch creation**

I’m deciding to revert the file to a clean state and then apply all modifications via regex-based method replacements to avoid inconsistent partial edits. To ensure precision, I’ll manually craft a patch capturing all intended changes with exact context from the original, targeting specific methods and additions, then apply it with git.

**Generating detailed patch steps**

I'm outlining a comprehensive patch by breaking down the extensive code modifications into sequential chunks for clarity and accuracy, planning to carefully replace and update methods, insert helpers, and adjust logs and calculations step-by-step.

**Planning PowerShell script file modifications**

I'm outlining a PowerShell script approach to modify the target file by loading lines into a list, finding indexes of key code markers, and inserting, replacing, or removing lines accordingly. This will let me perform all changes deterministically and avoid quoting or in-line command issues. I'll create `apply_fairness.ps1` to implement these sequential edits with clear, maintainable logic.

**Refining script index searches within method scopes**

I see the script's global index searches might target wrong occurrences across methods, risking misplaced edits. I'll revise it to find line indices strictly within specified method start and end ranges, crafting helper functions to scan line-by-line in that range. This way, modifications like inserting near 'var personnelTasks = decisionVars' will be precise and safe. I'll overhaul the script accordingly before running.

**Analyzing duplicate insertion issues**

I'm untangling why the script inserted duplicate lines like `var historicalWorkloads` twice due to running multiple insertions without removing originals. It looks like repeated insertions happened because the script added blocks twice or didn’t clean old lines before inserting, causing confusing duplicates. Given this complication, I’m leaning toward scrapping the insertion approach and instead using a full method text replacement via string replace to avoid duplicates and simplify the update, so I’ll revert and prepare for that next.

**Planning global string replacements**

I'm planning to implement modifications by reading the entire file as text and performing exact string replacements for various method blocks and snippets to ensure precision. I'll write a PowerShell script that reads the file, extracts original method code sections for accuracy, and then replaces them sequentially with new versions, carefully handling line endings and avoiding duplicate insertions. This approach should keep the process manageable while guaranteeing exact changes.
