 9  # Input: NIP-35 event dict with tags field
10  # Output: {"passed": bool}
11  #
12  # Steps:
13  #   1. Extract 'entry_id' tag value from tags
14  #   2. Query database or cache for existing entries with same entry_id
15  #   3. Return {"passed": False} if entry_id already exists
16  #   4. Return {"passed": True} if entry_id is unique
17  #
18  # Edge cases:
19  #   - Missing entry_id (other rules should catch this)
20  #   - Empty entry_id string (treat as unique but invalid)
21  #
22  # Dependencies: Database access (sqlite3 or external API call)
23  # Estimated complexity: Low (15-20) lines
24  # Priority: High (prevents duplicate indexing)
