 Bookmann tries multiple strategies to match books:
 
-1. **By UUID**: Most reliable if your book files have unique IDs
-2. **By file path**: Matches exact file path
-3. **By title + author**: Fallback for unmatched books
+1. **By UUID**: Most reliable if your book files have unique IDs (confidence: 1.0)
+2. **By SHA-256**: Hash-based matching for reliable identification (confidence: 0.9)
+3. **By file path**: Matches exact file path and creates device alias (confidence: 0.7)
+4. **By title + author**: Fallback for unmatched books (confidence: 0.5)
+5. **By title only**: Last resort match (confidence: 0.4)
+
+### SHA-256 Matching (Phase 7 Enhancement)
+
+Bookmann now supports SHA-256 hash matching for reliable book identification:
+
+```json
+{
+  "books": [
+    {
+      "sha256": "a1b2c3d4e5f6...",
+      "file_path": "/mnt/onboard/Book.epub",
+      "percentage": 0.65,
+      "page": 142,
+      "total_pages": 310
+    }
+  ]
+}
+```
+
+**Benefits**:
+- Works even if file path changes
+- Reliable across device re-formats
+- Automatic device file alias creation
+- Per-annotation SHA-256 support for mixed-book syncs
+
+### Device File Alias System
+
+When a book is matched with a file path, Bookmann automatically creates a device file alias:
+
+- **UUID + FilePath**: Creates alias with confidence 1.0
+- **SHA-256 + FilePath**: Creates alias with confidence 0.9
+- **FilePath only**: Creates alias with confidence 0.7
+- **Title match + FilePath**: Creates alias with confidence 0.5-0.7
+
+Once created, aliases enable future syncs without UUID or SHA-256:
+
+```json
+{
+  "books": [
+    {
+      "file_path": "/mnt/onboard/Book.epub",
+      "percentage": 0.70
+    }
+  ]
+}
+```
+
+### Per-Annotation SHA-256
+
+Sync bookmarks/notes/highlights for multiple books in one request:
+
+```json
+{
+  "highlights": [
+    {
+      "text": "Quote from book 1",
+      "pos0": "/6/4[chap1]!/4/2/1:0",
+      "pos1": "/6/4[chap1]!/4/2/1:50",
+      "color": "#ffff00",
+      "book_sha256": "abc123..."
+    },
+    {
+      "text": "Quote from book 2",
+      "pos0": "/6/4[chap1]!/4/2/1:0",
+      "pos1": "/6/4[chap1]!/4/2/1:50",
+      "color": "#00ff00",
+      "book_sha256": "def456..."
+    }
+  ]
+}
+```
