10  # Output: {"passed": bool}
11  #
12  # Steps:
13  #   1. Extract 'v' tag value from tags
14  #   2. Compare against supported version list (currently only "1" is supported per NIP-35)
15  #   3. Return {"passed": False} if version is not "1"
16  #   4. Return {"passed": True} if version is "1"
17  #
18  # Edge cases:
19  #   - Missing 'v' tag (reject as unsupported)
20  #   - Multiple 'v' tags (take first occurrence)
21  #   - Empty version string (reject as unsupported)
22  #
23  # Dependencies: None (stdlib only)
24  # Estimated complexity: Low (10-15) lines
25  # Priority: High (foundational schema validation)
