Local CDSL Engine
This package rebuilds cad.cdsl.llm.v1 models through the CDSL-only path:
sketch_solver -> llm_compiler -> llm_engine -> STEP
Supported profiles are defined by SHAPE_GENERATORS in sketch_solver.py.
Supported feature atomic operations are defined by the dispatch in llm_engine.py
and their required parameters are defined by REQUIRED in llm_compiler.py.
Their human-readable contract is in profile_schema.json; the complete,
machine-enforced CDSL object contract is in cdsl_schema.json.
The Studio only accepts self-contained profile data and requires successful
engine=cdsl_only output. It never uses the legacy translator fallback or
compiler_context.
Engine schema maintenance
profile_schema.json and cdsl_schema.json together are the source of truth
for the engine contract exposed to the CAD Agent and the backend validator.
Any addition, removal, rename, or
parameter-contract change in sketch_solver.py, llm_compiler.py, or
llm_engine.py must update both files in the same change.
backend/tests/test_profile_schema.py fails when the registered profiles or
supported atomic operations diverge from the document.
