+🎯 **What:** The `group_photos` function in `Cachyos/Scripts/WIP/gphotos/Splitter.py` had high cognitive complexity due to a deeply nested inner loop.
+💡 **Why:** Deep nesting makes the code harder to read, maintain, and reason about. By extracting the core file processing logic into smaller, dedicated helper functions (`process_file`, `ensure_space_in_group`, and `move_file_to_group`), the structure becomes clearer, and the iteration state can be managed explicitly through returns.
+✅ **Verification:** Validated that `ruff check` passes and the existing test suite (`python3 Cachyos/Scripts/WIP/gphotos/test_splitter.py`) passes perfectly, confirming that group counting, sizing, and moving boundaries all function properly without regression.
+✨ **Result:** A simplified `group_photos` function with significantly reduced nesting and cognitive complexity, promoting cleaner code health.
