CFDL

This example uses pack contracts in contracts.cfdl for lease, construction stub, and exit; standalone streams for ops revenue and ops expense (per guidance).

Full developer lifecycle split across files: time.cfdl (phases), structure.cfdl (entities), contracts.cfdl (CRE pack contracts). Entry is model.cfdl with version, model, use pack, time, and imports.
