WebAssembly runtime targets the latest specification, supporting instructions except VectorInstructions. Includes proposals like Tail Call and Wasm GC. Allows invoking functions, handling imports, and managing strings.

Implements a single-writer concurrent hashmap allowing lock-free, wait-free reads. Supports coroutines, ensuring non-blocking operations, and uses left-right concurrency for efficient data management.

Annotation-driven virtualisation of functions into WebAssembly binaries, enabling native or VM execution with unified interface, in-process updates, sandboxed execution and A/B testing.
