# llimphi-wasm-runner

The host side of Tier 3 WASM apps.

`WasmGuest` loads a `.wasm` following the `llimphi-wasm-app-sdk` ABI, instantiates
it with wasmi and runs its Elm loop:

1. `wasm_init` builds the guest's `Model` (it lives in the instance).
2. `wasm_view` returns a serialized `WireNode`; we deserialize and cache it.
3. `wire_to_view` materializes it into a real Llimphi `View<RunnerMsg>`.
4. A click emits `RunnerMsg::Guest(bytes)`; `WasmGuest::dispatch` bounces those
   bytes back to `wasm_dispatch` and refreshes the view.

The host keeps a single live `Store` per app, so the `Model` persists between
frames — exactly Llimphi's Elm contract, only with the transition running on the
other side of the WASM boundary.

It is the Linux-side twin of wawa's WASM app executor (`sys_render_frame` +
capabilities by physical boundary): the same spirit, another host.
