+### Agent Model Used
+- Claude Opus 4.5
+
+### File List
+
+| File | Action | Description |
+|------|--------|-------------|
+| `public/images/auth-pattern.svg` | Created | Geometric dot pattern SVG using Warm Gold at 6% opacity (138 bytes) |
+| `resources/css/app.css` | Modified | Added `.auth-pattern` CSS class with pseudo-element overlay |
+| `resources/views/components/layouts/auth/split.blade.php` | Modified | Applied `auth-pattern` class to form panel |
+| `tests/Feature/Auth/AuthBackgroundPatternTest.php` | Created | 12 tests covering pattern asset, CSS, and layout integration |
+
+### Change Log
+
+- **AC1**: Created `auth-pattern.svg` - geometric dot pattern with Warm Gold (#A68966) at 6% opacity, 20x20px tiles, 138 bytes
+- **AC2**: Applied pattern to auth split layout form panel via `auth-pattern` class
+- **AC3**: Pattern opacity set to 6% (within 5-8% range) - subtle and non-distracting
+- **AC4**: Implemented using CSS pseudo-element overlay with `background-repeat: repeat` and `pointer-events: none`
+- **AC5**: SVG is only 138 bytes (well under 5KB), loads efficiently, works without JavaScript
+- **AC6**: Pattern uses `repeat` for seamless scaling, no horizontal scroll issues
+
+### Completion Notes
+
+- Used Option A (Geometric) as recommended - simple dot pattern for clean, modern aesthetic
+- Used Option 2 (Pseudo-element Overlay) for better control and accessibility
+- All 12 new tests pass
+- All 45 auth tests pass
+- All 20 RTL/LTR layout tests pass
+
+### Status
+Ready for Review
