 ### 4. Refactor Shell Configuration Architecture
 
-- [ ] Consolidate PATH modifications into single, organized section in `commonrc.sh.tmpl`
-- [ ] Create modular PATH loading system (one block per tool with conditional checks)
-- [ ] Separate PATH, environment variables, and shell completions into logical sections
-- [ ] Document load order (`.bashrc` → `commonrc.sh` → `.bash_aliases`)
-- [ ] Add comments explaining each tool's PATH modification
-- [ ] Eliminate duplicate PATH additions
-- [ ] Create standard pattern for conditional tool loading
-- [ ] Add PATH deduplication function
-- [ ] Move WSL-specific settings to dedicated section (currently at commonrc.sh.tmpl:109-114)
-- [ ] Organize tool sections alphabetically or by category

+- [x] Sync tool order between Bash and Fish configs for consistency
