  - aui-build runs React Compiler over packages that depend on tap and remaps `react/compiler-runtime` to the tap shim subpath, so compiled hooks and components work both in React components and inside tap resource renders
  - `@assistant-ui/tap/react-shim` exports `useMemoCache` (tap inside a resource render, `React.__COMPILER_RUNTIME.c` otherwise, with a React 18 polyfill); new `@assistant-ui/tap/react-shim/compiler-runtime` subpath mirrors `react/compiler-runtime`'s `c` export
  - tap implements `useSyncExternalStore` and a no-op `useDebugValue`; `useSubscribable` now builds on `useSyncExternalStore` so its store reads stay visible to the compiler
  - `AssistantProviderBase` opts out via `"use no memo"` because the runtime receives options through an effect inside a re-rendered child element

## 0.8.0

### Minor Changes

- feat: drop the experimental deps array from `useResource`/`useResources` and make `useResources` take an array of elements directly instead of a `getElements` callback. The React Compiler memoizes element inputs, so the manual dependency arrays were redundant; re-renders are now controlled by element identity. ([@Yonom](https://github.com/Yonom))

The React bridge hosts (useResource, useResources, useTapRoot) now also commit in useEffect instead of useLayoutEffect. ([@Yonom](https://github.com/Yonom))

### Patch Changes

- [#4318](https://github.com/assistant-ui/assistant-ui/pull/4318) [`1b6a0d6`](https://github.com/assistant-ui/assistant-ui/commit/1b6a0d6ae40b343b233c8c12ab119b13c43cb69b) - fix: React parity for useReducer and StrictMode. User reducers now compute during render instead of eagerly at dispatch (matching React, which reserves eager computation for useState), so dev-mode reducer invocation counts and kept results match React; a same-state dispatch now renders once like React instead of bailing out at dispatch. The React bridge keeps one host fiber across both StrictMode render passes (hosted identities match across passes like React's own hook state) and lets React's strict replay drive the effect cycle (mount, unmount, mount). ([@Yonom](https://github.com/Yonom))

- [#4318](https://github.com/assistant-ui/assistant-ui/pull/4318) [`1b6a0d6`](https://github.com/assistant-ui/assistant-ui/commit/1b6a0d6ae40b343b233c8c12ab119b13c43cb69b) - feat(tap): resources carry all hook arguments; elements are `{ hook, args }` ([@Yonom](https://github.com/Yonom))

  A `ResourceElement` is now `{ hook, args }` (was `{ type, props }`): the underlying hook plus the full tuple of arguments to call it with. This lets a resource take multiple positional arguments, exactly like a hook, and makes hosting just `hook(...args)`:

  ```ts
  const usePair = (a: number, b: string) => ({ a, b });
  const Pair = resource(usePair);
  const element = Pair(1, "hi"); // { hook: usePair, args: [1, "hi"] }
  ```

  The single-object case is unchanged ergonomically (`Counter({ initialValue: 0 })` still works; its `args` is just `[{ initialValue: 0 }]`), so existing resources and call sites are unaffected. `resource()`'s overloads collapse into one variadic signature, and the `fnSymbol` / `callResourceFn` indirection is gone (the element holds the hook directly; `renderResourceFiber` calls `fiber.hook(...args)`).

  Breaking (internal/advanced):
  - The second type parameter of `Resource` / `ResourceElement` / `ContravariantResource` now means the argument tuple `A extends readonly unknown[]` rather than a single payload `P`. Explicit two-arg annotations must wrap the payload in a tuple (e.g. `ResourceElement<R, [Props]>`).
  - A resource's identity is now its hook. Reading `element.props` becomes `element.args[0]`; reading `element.type` becomes `element.hook`. `attachTransformScopes` is now keyed by (and called with) the hook rather than the factory.
  - `useResource(element, deps)`'s second arg is unchanged in behavior (renamed `argsDeps`).

- [#4318](https://github.com/assistant-ui/assistant-ui/pull/4318) [`1b6a0d6`](https://github.com/assistant-ui/assistant-ui/commit/1b6a0d6ae40b343b233c8c12ab119b13c43cb69b) - refactor: adopt the extracted-hook convention for resources ([@Yonom](https://github.com/Yonom))

  A resource body is a hook, so resources are now authored as a `use`-prefixed hook
  wrapped with `resource()`:

  ```ts
  const useCounter = () => { ... };
  const Counter = resource(useCounter);
  ```

  `resource()` turns a hook into a Resource; `useResource(Counter(props))` turns it
  back into a hook call. Extracting the body to a `use`-prefixed hook lets React's
  stock rules-of-hooks and exhaustive-deps lint resource bodies directly. No
  public API or runtime behavior changes.

- [#4318](https://github.com/assistant-ui/assistant-ui/pull/4318) [`1b6a0d6`](https://github.com/assistant-ui/assistant-ui/commit/1b6a0d6ae40b343b233c8c12ab119b13c43cb69b) - refactor: rename the root APIs to `useTapRoot` / `createTapRoot` and make them callback-based ([@Yonom](https://github.com/Yonom))

  `useResourceRoot(element)` is now `useTapRoot(fn)` and `createResourceRoot().render(element)` is now `createTapRoot(fn)`. Both take a render callback instead of a pre-built resource element, so you no longer have to wrap a hook in `resource()` just to host it as a root. The callback must be a **named** function expression (so React's rules-of-hooks lints the body):

  ```ts
  // before
  const root = createResourceRoot();
  const handle = root.render(Counter());
  handle.getValue();

  // after
  const root = createTapRoot(function CounterRoot() {
    return useResource(Counter());
  });
  root.getValue();
  ```

  `createTapRoot` returns `{ getValue, subscribe, unmount }` directly (no separate `.render` step).

  `flushResourcesSync` is also renamed to `flushTapSync`, to match the `tap` naming of the root APIs (and to stay distinct from react-dom's `flushSync`).

## 0.6.0

### Minor Changes

- [#4282](https://github.com/assistant-ui/assistant-ui/pull/4282) [`01cf957`](https://github.com/assistant-ui/assistant-ui/commit/01cf957c209b1a58c69f5621565397de6d1eb794) - feat: React integration ([@Yonom](https://github.com/Yonom))

  `@assistant-ui/tap` now requires `react` as a peer dependency and ships a React integration:
  - Resource API at the package root: `useResource` (host a resource element), `useResources` (keyed lists), and `useResourceRoot` (a subscribable `{ getValue, subscribe }` boundary). Each is isomorphic: it works inside a resource render and inside a React component.
  - Author resource state and effects with plain React hooks. A React dispatcher installed around every resource render makes `import { useState } from "react"` (and `useReducer`/`useRef`/`useMemo`/`useCallback`/`useEffect`/`useEffectEvent`/`use`) route to tap inside a resource, with no build step. It also backs `react/compiler-runtime`'s `useMemoCache`, so React Compiler output runs in a resource without a `"use no memo"` opt-out. Hooks tap has no equivalent for throw when called inside a resource.
  - `@assistant-ui/tap/react-shim`: a runtime drop-in for `"react"` that assistant-ui's own packages are built against (their `react` imports are pre-routed to it), so they route to tap inside a resource render and to React otherwise without depending on the consumer's bundler. It ships no type declarations; keep importing from `"react"` so React's own types apply.
  - Also exports `resource`, `withKey`, `createResourceRoot`, `flushResourcesSync`, the `createResourceContext` / `withContextProvider` context API, and the `Resource` / `ContravariantResource` / `ResourceElement` types.

### Patch Changes

- [#4085](https://github.com/assistant-ui/assistant-ui/pull/4085) [`01244a5`](https://github.com/assistant-ui/assistant-ui/commit/01244a56026ee92bd4e49cb985136f9eb6d45154) - chore: update dependencies ([@Yonom](https://github.com/Yonom))

- [#4097](https://github.com/assistant-ui/assistant-ui/pull/4097) [`1e21076`](https://github.com/assistant-ui/assistant-ui/commit/1e2107648bc281f1673f4ad053fd019b28a602d0) - build(x-buildutils): migrate `aui-build` from `ts.createProgram` to `tsdown` with `unbundle: true` ([@Yonom](https://github.com/Yonom))

  Tsdown drives both JS and `.d.ts` emission. Reference-directive restoration is preserved (tsdown/oxc drop `/// <reference>` lines, so we re-inject them in a `build:done` hook). `deps.skipNodeModulesBundle: true` keeps the old "never bundle anything from `node_modules`" behavior — devDependencies stay external instead of getting inlined into `dist`.

  Side fixes the new strict dts pipeline surfaced:
  - `@assistant-ui/tap`: dropped the `fnSymbol` brand from the public `ResourceElement` type. It referenced an `@internal` symbol that `stripInternal` removed from emit, leaving the published `.d.ts` with a dangling reference.
  - `@assistant-ui/store`: un-marked `ClientSchema` as `@internal`. It was already re-exported from the public package index; treating the re-export as authoritative.
