Designing PIC-X: From Specification to Architecture to Code

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.
