Compiler Surface Policy

This page defines the root-level sc_neurocore.compiler API boundary. The package facade exports the stable symbols used by ordinary compiler clients. Some modules remain direct public modules because existing workflows import them by module path. The remaining modules are internal build tools used by the compiler facade, deployment facade, or hardware evidence pipeline.

Use from sc_neurocore.compiler import ... for facade symbols. Import direct public modules only when their module path is shown below. Internal build tools can change without a deprecation window.

Enforcement

tests/test_compiler_surface_policy.py reads this table and the filesystem on each run. A new root compiler module must either join the package facade, become a direct public or compatibility module, or appear here as an internal build tool with a clear reason.
