+# RAID WebDAV Integration - Complete
+
+## Date: 2026-05-17
+## Status: Phase 1 Complete (100%)
+
+## Implemented Features
+
+### Core RAID Module
+- ✅ parity.rs (105 lines) - XOR Parity calculation
+- ✅ level_5.rs (197 lines) - RAID 5 read/write logic
+- ✅ controller.rs (134 lines) - RAID controller (RAID 0/1/5)
+- ✅ exporter.rs (95 lines) - RAID to virtual disk export
+
+### WebDAV Integration
+- ✅ raid_webdav_auto.rs (135 lines) - Auto-mount WebDAV server
+- ✅ Auto-mount sparseimage on startup
+- ✅ Mount point verification
+- ✅ WebDAV handler configuration
+

+
+## Usage
+
+### Start RAID WebDAV Server
+```bash
+cargo run --bin raid_webdav_auto \
+  --vdisk-path data/raid_simple.sparseimage \
+  --mount-name RAID_AUTO \
+  --port 4933
+```
+
+### macOS Finder Mount
+```
+1. Finder → Cmd+K
+2. http://localhost:4933/webdav
+3. Connect (Guest/Guest)
+4. Access test_video.mp4 (258MB)
+```
+
+## Performance
+
+- Virtual disk: 258MB test file
+- Mount time: <3 seconds
+- WebDAV overhead: minimal (local filesystem)
+
+## Next Steps
+
+1. Performance testing (throughput measurement)
+2. RAID 6 implementation (Reed-Solomon)
+3. RAID 10/50/60 (nested RAID)
+4. Multi-user WebDAV support
+
+## Code Quality
+
+- Total lines: 666 (RAID + WebDAV)
+- Tests: 5 passed
+- Coverage: parity, level_5, exporter
