The web client is real: `tethercore` with the full iroh stack now builds for wasm32-unknown-unknown, producing tethercore.wasm. - Runtime abstraction: a `Spawner` replaces the bare tokio runtime Handle across the Transport trait + Engine + all transports — tokio Handle on native, the browser event loop (wasm-bindgen-futures::spawn_local) on wasm. The engine no longer builds a tokio multi-thread runtime on wasm (there are no OS threads). - IrohTransport's internal tasks (re-register loop, blob fetch) route through the Spawner; its 30s timer uses n0-future (iroh's cross-platform async) instead of tokio::time, which isn't available on wasm. - iroh on wasm: default-features=false + tls-ring (ring builds for wasm with a wasm-capable clang) + iroh-gossip net; getrandom uses its wasm_js backend. - build-web.sh documents the toolchain (Homebrew LLVM clang for ring's C, the getrandom rustflag) and produces the .wasm. Native (default + iroh + all clients) is byte-unaffected and verified clean throughout. Remaining for a running web app: wasm-bindgen JS bindings + a browser shim (relay-only in-browser).
