Adapters

An adapter in this stack is not a SvelteKit adapter in the official sense. It does not replace the compiler and it does not start listenHTTP. adaptWorkspace({ ws, adapter, out }) reads ws/.svelte-d/manifest.json and copies the artifacts that adapter knows how to ship. The names are static, libwasm-spa, vibe0, and vibe0-proxy. bunx svelte-kit-d adapt static --out build is the CLI form.

static is files. libwasm-spa is the wasm module plus the JS glue that instantiates it. vibe0 is the host binary. vibe0-proxy is the host that reverse-proxies Vite. None of them parse Svelte with svelte/compiler. If you need a new output shape, add an adapter that consumes the manifest; do not add a Node server “just for preview.”
