Security Metadata Field Decode

This structural rule validates that each known MISB ST 0102 tag value can be decoded by the field codec defined for that tag.

What This Test Does​

The rule:

  • decodes the nested security local set structure
  • applies the tag-specific MISB ST 0102 field decoder to each known tag
  • reports invalid field length, malformed encoding, or other field-level decode failures

✅ Pass Criteria​

The test passes when all known MISB ST 0102 fields in the detected security local sets decode successfully.

❌ Fail Criteria​

The test fails when a known MISB ST 0102 field has an invalid encoded value, invalid field length, or other decode error.

Notes​

Unknown-tag handling is covered separately by the Unknown Tag for Revision rule. This rule focuses on tags that are known to the resolved MISB ST 0102 schema but whose raw value cannot be decoded correctly.
