Wasm Forge

Wrap any file inside a valid, byte-exact WebAssembly envelope with a real SHA-256 — then verify and unwrap it. And run real .wasm right here: it parses the module, auto-stubs imports, and calls the exports.

Honest labeling: the envelope's reversible flag is set only after a self-verified byte-exact round-trip. This is a container with an integrity hash — not encryption. The module exports a no-op execute stub so it's a valid, instantiable module.
