  "$comment": "MSP-1 v1.0.1 uses object form as canonical for trust. level is required and uses low, medium, or high. verificationLevel is separate from level and uses self-declared or verified. Authority meaning belongs in the authority term; legacy authoritative trust values should receive advisory compatibility handling.
