CALM

CALM (Common Architecture Language Model) is a machine-readable specification for describing software architecture as versioned code. It defines a JSON Schema for nodes, relationships, flows, and controls so an architecture can be validated, diffed, and governed in a pipeline rather than drawn in a diagram.
