- Share frontend loading, package selection, contracts, and FFI parsing between Node and native clients.
- Preserve collection layouts and optional method returns while lowering long nullish chains without recursive stack growth.
- Rebuild the frontend from TypeScript through native lowering and C emission with matching output.
- Compile the production C emitter and reproduce its output across native generations.
- Support the union operations, recursive spreads, and compression options needed by the emitter.
- Fix temporary ownership and verify the bootstrap and shared call operands with both backends and sanitizers.
- Add native RequestInit, AbortSignal, and streaming request and response body support.
- Lower the static fetch surface through both C and LLVM without the embedded engine.
- Add differential, Node-typing, sanitizer, and regression coverage.
