+# Async
+
+Effect View components run synchronously by default. Apply `Async.async` when a
+component must wait for an asynchronous Effect before it can return JSX. The
+component suspends while the Effect runs and accepts React Suspense props such
+as `fallback`.
+
+```tsx title="src/UserCard.tsx"
+import { Effect } from "effect"
+import { Async, Component } from "effect-view"
+import { loadUser } from "./api"
+
+export const UserCard = Component.make("UserCard")(
+  function* ({ userId }: { readonly userId: string }) {
+    const user = yield* Component.useOnChange(
+      () => loadUser(userId),
+      [userId],
+    )
+
+    return <article>{user.name}</article>
+  },
+).pipe(Async.async)
+```
+
+Pass a fallback when rendering the component:
+
+```tsx
+const User = yield* UserCard.use
+
+return <User userId="123" fallback={<p>Loading user...</p>} />
+```
+
+Or configure a default fallback once:
+
+```tsx
+export const UserCard = Component.make("UserCard")(
+  function* ({ userId }: { readonly userId: string }) {
+    const user = yield* Component.useOnChange(
+      () => loadUser(userId),
+      [userId],
+    )
+
+    return <article>{user.name}</article>
+  },
+).pipe(
+  Async.async,
+  Async.withOptions({ defaultFallback: <p>Loading user...</p> }),
+)
+```
+
+## Hook ordering
+
+**Important:** Do not use React hooks or Effect View hook helpers after an
+asynchronous computation in the component body. After the computation suspends,
+the generator continuation runs outside React's synchronous render phase.
+
+Place every hook before the first operation that may suspend:
+
+```tsx
+import { useState } from "react"
+
+const UserCard = Component.make("UserCard")(
+  function* ({ userId }: { readonly userId: string }) {
+    // Hooks and hook helpers go before asynchronous work.
+    const [showDetails, setShowDetails] = useState(false)
+
+    // This may suspend, so no hooks may be used after it.
+    const user = yield* Component.useOnChange(
+      () => loadUser(userId),
+      [userId],
+    )
+
+    return (
+      <article>
+        <button onClick={() => setShowDetails((value) => !value)}>
+          {user.name}
+        </button>
+        {showDetails && <p>{user.bio}</p>}
+      </article>
+    )
+  },
+).pipe(Async.async)
+```
+
+## Memoization
+
+An async computation starts whenever its component renders. Apply
+`Memoized.memoized` after `Async.async` to prevent an unrelated parent render
+from restarting an async child whose props have not changed:
+
+```tsx
+import { Async, Component, Memoized } from "effect-view"
+
+export const UserCard = Component.make("UserCard")(
+  function* ({ userId }: { readonly userId: string }) {
+    const user = yield* Component.useOnChange(
+      () => loadUser(userId),
+      [userId],
+    )
+
+    return <article>{user.name}</article>
+  },
+).pipe(
+  Async.async,
+  Memoized.memoized,
+)
+```
+
+Async components compare props with `Object.is` by default and ignore the
+`fallback` prop during that comparison. A changed `userId` renders the child
+again, closes the previous dependency scope, and runs `loadUser` for the new
+value.
+
+If props contain immutable objects or arrays that may be recreated with the same
+content, use `Equal.asEquivalence()` for full structural equality:
+
+```tsx
+import { Equal } from "effect"
+import { Async, Component, Memoized } from "effect-view"
+
+export const UserCard = Component.make("UserCard")(
+  function* (props: { readonly user: { readonly id: string } }) {
+    const details = yield* Component.useOnChange(
+      () => loadUser(props.user.id),
+      [props.user.id],
+    )
+
+    return <article>{details.name}</article>
+  },
+).pipe(
+  Async.async,
+  Memoized.memoized,
+  Memoized.withOptions({
+    propsEquivalence: Equal.asEquivalence(),
+  }),
+)
+```
+
+Supplying `propsEquivalence` replaces the async component's default comparison,
+so `fallback` is also included in this structural comparison.

 ## Synchronous and asynchronous components

+A regular Effect View component runs its body during React render. Effects
+executed directly by that body—including setup passed to `useOnMount`,
+`useOnChange`, or `useLayer`—must complete synchronously every time they run.
+Yielding services and reading synchronous state is fine; sleeping, fetching, or
+awaiting a promise is not.
 
-Use `Async.async` when render genuinely depends on an asynchronous Effect. The
-component then suspends and accepts React Suspense props such as `fallback`:
+Choose the integration that matches the asynchronous work:
 
-```tsx title="src/UserView.tsx"
-import { Async, Component, Memoized } from "effect-view"
-import { loadUser } from "./api"
-
-export const UserView = Component.make("UserView")(
-  function* (props: { readonly userId: string }) {
-    const user = yield* Component.useOnChange(
-      () => loadUser(props.userId),
-      [props.userId],
-    )
-
-    return <h2>{user.name}</h2>
-  },
-).pipe(
-  Async.async,
-  Async.withOptions({ defaultFallback: <p>Loading user...</p> }),
-  Memoized.memoized,
-)
-```
-
-Use it from an Effect View parent in the usual way:
-
-```tsx
-const User = yield* UserView.use
-
-return <User userId={selectedUserId} />
-```
-
-`Memoized.memoized` prevents an unrelated parent re-render from restarting an
-async child whose props have not changed. A changed `userId` creates a new
-dependency scope, cleans up the previous one, and runs `loadUser` again.
-
-An async component's rejected Effect is handled by the nearest React error
-boundary. Suspense handles waiting, not failures.
-
-For server data that should be cached, refreshed, and shared, prefer the
-[Query module](./query) over a raw async component.
+- Make the component asynchronous with [`Async.async`](./async) when it must
+  wait for a one-off asynchronous Effect before producing JSX. The component
+  suspends while it waits.
+- Use [Query](./query) for server reads that need caching, sharing, refresh, or
+  invalidation.
+- Use [Mutation](./mutation) for user-triggered writes with observable pending
+  and error state.
+- Use `useRunPromise` or `useCallbackPromise` for asynchronous event work that
+  does not need Mutation state.
+- Use a post-commit hook with a scoped fiber for subscriptions or background
+  work tied to the component lifecycle.
