Packages

This project is organized as a set of focused Julia packages. The table below summarizes responsibilities and typical usage.

Package	Purpose	Typical Use
`JCGECore`	RunSpec, sections, sets/mappings, scenarios, validation, and closure-condition roles	Define model structure and closure choices
`JCGEBlocks`	Reusable CGE blocks, auxiliary-quantity equations, and stable equation-condition keys	Assemble production/household/market systems, make supplementary quantities endogenous, and declare accounting checks
`JCGERuntime`	Role-aware compilation, solver execution, residual diagnostics, and experiment workflows	Solve a RunSpec and run parameter/policy batches
`JCGECalibrate`	SAM loading and calibration	Derive parameters and starting values
`JCGEOutput`	Equation rendering, results containers, accounting-check reporting, and satellite quantities	Export equations, tidy results, physical-flow projections, balance checks, and DualSignals
`JCGEExamples`	Reference models	Canonical model ports and tests
`JCGEImportData`	Canonical IO/SAM schema	Convert external data to CSV inputs
`JCGEImportMPSGE`	MPSGE.jl importer	Translate MPSGE objects to RunSpecs
`JCGEAgentInterface`	MCP-compatible interface for agents	AI-assisted discovery, modeling guidance, solving, validation, and reporting

Each package has its own documentation site and API reference. This repository keeps the ecosystem narrative consistent, but package-specific details belong in those package docs.
