Designing PIC-X. Deriving an Initial PIC Context of Authority.

PIC-X receives an OAuth access token at the selected realm token endpoint, validates it, and derives the initial PIC Context of Authority, or PCA. A PCA is the logical Context of Authority. Its signed representation is a PIC PCA COSE. PIC-X then returns a realm-signed PIC Token JWT carrying a settled PIC Continuity COSE in pic.root.

PIC-X stands for Provenance Identity Continuity Exchange.

Verifiable Authority Continuity across execution boundaries.

PIC has reached a point where the questions are becoming practical:

How can we use it? How can we test it? What should a real implementation look like?

Answering those questions requires more than specifications. It requires building the components that enable software engineers and architects to experiment with PIC in real systems.
