- Keep typed callbacks on native paths while preserving receivers, evaluation order, and method replacement.
- Preserve caught class identity, collection narrowing, and missing indexed values across typed code.
- Add standard terminal access and filesystem error metadata with differential coverage and versioned runtime compatibility.
- Add native worker execution with isolated module state, structured messages, and lifecycle controls.
- Support shared buffers and integer atomics with coordinated runtime ownership and cancellation.
- Extend compiler, runtime-pack, differential, and compatibility coverage for native concurrency.
