M1: three realms, one TodoMVC - #150

Conversation
The runtime component (kernel crate + world) boots in a SharedWorker over a kv import and wasi:http, serves device state, the app registry (bundles fetched from the home origin, assets re-hashed), in-memory tasks per app, and a long-poll event export; app sessions get a bound MessagePort that reaches exactly the tasks mirror and the three asset calls. The visor component (Dioxus over stream-dom) renders the strip and two drawer tenants with voices as types; the TodoMVC app component keeps its state in the tasks service. Glue: boot/worker/frame, a WIT- over-MessagePort proxy, the frame policy, the hash-pinned srcdoc loader, build + translate, five Playwright scenarios. Found on the way and recorded in docs/design.md: generate! must not set async: true (the translator, not wasm-tools, catches the async lowering of a sync WIT function); and a polyengine liveness bug — a parked driver's stale pendingHostCalls snapshot — fixed upstream (#289) and consumed here at that git revision with the pre-<sha> translator asset.

Runtime component in the SharedWorker (kernel crate: device, app registry with asset re-hashing, in-memory
tasks, long-pollevents,apps.abort), visor component (Dioxus over stream-dom; voices as types; strip + Apps/Settings tenants), TodoMVC app component overpolyvisor:app/tasks, and the glue:boot.ts/worker.ts/frame.ts, WIT-over-MessagePort RPC, the frame policy on stream-dom'sPolicy, hash-pinned srcdoc loader withdefault-src 'none', build + translate, e2e.Gates:
just cigreen;deno task e2e5/5 — boot, open-app (opaque frame; strip geometry immobile), todo-roundtrip (through the worker, survives a tab reload with a second tab holding the worker), frame-network-dead (zero requests from the frame), instantiates-without-jspi.Two findings recorded in
docs/design.md:generate!never setsasync: true; the translator (notwasm-tools validate) catches an async lowering of a sync WIT function, sositeis now part ofjust ci.pendingHostCallsrace snapshot) — fixed upstream in driver: a host call registered while a driver is parked wakes it (stale race snapshot) polyengine#289; this tree consumes polyengine at that git revision with thepre-<sha>translator asset until a release carries it.Deferred to M2: the browser-level frame-teardown scenario (needs a hostile fixture component; the path was exercised by the policy catching the example's outbound
href).Automerge armed.
