Designing PIC-X. Exchanging an OAuth Access Token for an Initial PCA.

PIC-X receives an OAuth access token, validates it, and converts it into the initial PCA from which the PIC lineage begins.

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.
