CPC Validation

CPC Validation is the reference validation framework for Constraint Physical Computing (CPC). It defines a canonical constraint IR, qualified RC, Digital, and FPGA execution backends, independent cross-backend semantic validation, and an RFC-0009 physical-evidence lifecycle. Version 0.6.0 adds the accepted RFC-0010 architecture for driven-dissipative open-system execution and referenced readout, together with an execution-specification model, conformance validation, and a simulated reference witness. The RFC-0009 P1 FPGA evidence remains the repository's concrete physical-execution milestone; RFC-0010 does not by itself establish a physical open-system realization.
