- Derive builtin call names from shared signatures and keep call semantics with their ABI contracts.
- Separate runtime dependency detection, exception metadata, and library policy from the core IR while preserving existing exports.
- Enforce the frontend signature boundary and validate native compilation and policy behavior.
- Remove C emission, debugging options, and automatic backend fallback.
- Complete LLVM lowering and native bootstrap coverage across supported targets.
- Link executables and libraries with precompiled C runtime packs, including iOS and Android.
- Compile production IR serialization and runtime dependency scans on both native backends
- Support native JSON callbacks and checked records with unknown payloads
- Verify native IR round trips and executable generation with focused sanitizer coverage
