- Preserve callback identity, receiver binding, and class references across unions and collections.
- Track record field presence independently of undefined values and improve native runtime behavior.
- Expand differential coverage and streamline CI bootstrap and compiler rebuild checks.
- 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.
- Preserve live class identity through interface receivers and object methods.
- Extend synchronous text reads and regular expression replacement callbacks.
- Keep unsupported generic dispatch boundaries explicit.
- Support concrete generic inheritance, forward references, and nullable substitutions.
- Bound recursive specialization demands while preserving independent concrete uses.
- Preserve class identity through checked assertions and contextual lowering.
- Sort primitive arrays with stable native ordering and pure conversion keys.
- Preserve sparse semantics and argument effects while avoiding callback overhead.
- Verify Unicode ordering and ownership across native and WASI paths.
- Support boolean, bigint, and mixed value keys in native Maps and Sets.
- Reuse key hashes and copy collections directly into compact storage.
- Preserve collection identity, ordering, iteration, and ownership behavior.
