Six diagram types (DFD, state machine, component, C4, ERD, dependency) compiled to GDS specifications with 27 verification checks and 223 tests. Each diagram type follows the standard DSL pattern: elements, model, compiler (GDSSpec + SystemIR), and domain-specific checks.
Demonstrates gds-software DFD DSL with a classic order processing scenario — 2 external entities, 3 processes, 2 data stores, 11 data flows. Includes 46 tests covering model, compilation, verification, canonical decomposition, and query API.
Alias duplicate imports with underscore prefixes so marimo treats them as cell-private. Fixes "was defined by another cell" errors in the verification and visualization guide notebooks.
Three diagram types compiling to GDS role blocks and composition trees: - CLD (Causal Loop Diagrams): stateless signal relay, h = g - SCN (Supply Chain Networks): stateful inventory dynamics, h = f ∘ g - VSM (Value Stream Maps): partially stateful process chains 11 domain verification checks (CLD-001..003, SCN-001..004, VSM-001..004), verification engine with union dispatch, 175 tests at 95% coverage.
Package overview, getting started tutorial, diagram types guide, verification guide, and 16 auto-generated API reference pages. Updated mkdocs.yml nav and ecosystem index.
