"""Frozen legacy engine paths.

``llm_compiler`` (thin CDSL to build_pack) and ``llm_engine`` (build_pack
executor) predate the session-based runtime and are not used by
``run_cdsl_only``.  ``exact_rebuild`` hosts the SolidWorks-exact fallback
rebuilds and the project-specific geometric compensations.

Do not extend these modules; new capability belongs in the session runtime
(``executors/``) or the schema contracts.  The top-level ``llm_compiler.py``
and ``llm_engine.py`` shims keep every historical import path working.
