Decoded claim inspection

JWT contents are untrusted until signature verification and application-specific claim validation succeed.

Trust and standards boundaries

Formatting is not schema validation, Base64 is not encryption, URL normalization is not a privacy guarantee, UUID metadata is not provenance, and decoded JWT claims are not trusted until cryptographic and application-specific validation succeeds. RS256 tools accept explicit PEM key formats and do not fetch issuer keys or make authorization decisions.
