+# 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`.
+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`.
