How to use this reference
Editorial lesson: trusted issuer and valid signature establish token provenance, not authorization for every consumer. Require explicit purpose at issuance and matching operation scope at consumption. Panel 1.12.3 release notes require a scope when generating tokens; Wings 1.12.2 release notes describe verifying subsystem-required scopes. Review the producer and consumer together.
