+# Workstation Organization
+
+## Problem
+Home directory was cluttered with 4+ years of project history (104GB) and redundant software packages.
+
+## Solution
+1. **Software Cleanup**: Two phases of package removal synced to Ansible (`state: absent`).
+2. **Project Audit**: Scripted identification of Git repositories.
+3. **Automated Removal**: Deleted 22 clean repositories that have remote origins.
+4. **Safety**: Retained dirty repos and repos without remotes.
+
+## Reclaimed
+- Disk Space: ~21 GB in Projects + ~2.4 GB in system packages.
