Why should you care about WebAssembly?
summary
WebAssembly is shown as a practical in‑process sandbox: real C binaries like dcraw compiled to wasm run inside a Go app without crashing the host, using the wazero runtime and the WASI/WASI‑style ABI for args and file I/O. Policy and extensibility examples include Trivy loading wasm modules from OCI for site‑specific scoring, and an HTTP‑wasm middleware ABI that lets sidecars host per‑request filters; the demos work in production‑style repos.
