-# Reusable workflow that performs every `npm publish` in this repo.
+# Single top-level workflow for every npm publish in this repo.
 #
-# Why this exists: npmjs.com Trusted Publishing accepts only ONE
-# (org, repo, workflow_filename, environment) tuple per package. If
-# `react-native` were published from `publish-release.yml` AND
-# `nightly.yml` directly, we'd need two Trusted Publisher entries per
-# package — npm rejects that. By moving every `npm publish` into this
-# single reusable workflow file, the OIDC `job_workflow_ref` claim
-# always resolves to `publish-npm.yml` regardless of which top-level
-# workflow triggered the run, so each package needs exactly one
-# Trusted Publisher entry pointing here.
+# Why: npmjs.com Trusted Publishing matches the `workflow_ref` OIDC claim,
+# which is always the TOP-LEVEL workflow filename. npm allows only ONE
+# trusted publisher per package, so every `npm publish` must originate
+# from the same top-level file. By consolidating all publish triggers
+# here, the OIDC claim is always `publish-npm.yml`.

+# React Native
+
+A framework for building native applications using React.
+
+This file provides guidance for coding agents working in this repository.
+
+## Repo structure
+
+React Native is a monorepo: the `react-native` package, the packages published alongside it, and the apps and tooling used to develop them.
+
+| Path | Contents |
+| --- | --- |
+| `packages/react-native/Libraries` | JavaScript source (Flow) — the legacy location, with code gradually moving to `src/private` |
+| `packages/react-native/src/private` | JavaScript source (Flow) |
+| `packages/react-native/ReactCommon` | Shared C++ — Fabric renderer, TurboModules, JSI, Yoga, `jsinspector-modern` |
+| `packages/react-native/ReactAndroid` | Android runtime (Kotlin, Java, JNI) |
+| `packages/react-native/{React,ReactApple}` | Apple runtime (Objective-C++, Swift) |
+| `packages/rn-tester` | RNTester — test app showcasing each core component and API, plus a `Playground` scratch surface |
+| `packages/*` | Other published packages — Metro config, Codegen, ESLint config, dev-middleware, React Native DevTools frontend |
+| `private/*` | Unpublished — the `helloworld` sample app, the `react-native-fantom` test runner |
+| `scripts/*` | Repository tooling — build, test, release, and CI scripts |
+
+Architecture notes live in `__docs__` directories beside the code they describe, indexed by [`__docs__/README.md`](__docs__/README.md). Treat them as reference for the subsystem you are working in, not as required reading.
+
+## Common commands
+
+Run these from the repository root:
+
+| Command | Purpose |
+| --- | --- |
+| `yarn test <path>` | Jest unit tests, found in `__tests__` directories |
+| `yarn fantom <path>` | [Fantom](private/react-native-fantom/__docs__/README.md) integration tests, named `*-itest.js` |
+| `yarn lint` | ESLint |
+| `yarn format` | Prettier and clang-format |
+| `yarn flow-check` | Flow |
+| `yarn start`, `yarn android` | Metro, and RNTester on Android. See [RNTester](packages/rn-tester/README.md) for iOS |
+
+Native builds use Gradle on Android, and CocoaPods or Swift Package Manager on iOS. See [Building from source](https://reactnative.dev/contributing/how-to-build-from-source).
+
+## Gotchas
+
+- JavaScript sources are typed with Flow, and the public API is exported from `packages/react-native/index.js`. TypeScript types are generated from those sources, and `packages/react-native/ReactNativeApi.d.ts` is a committed snapshot of that API — run `yarn build-types` to regenerate both whenever the public API changes.
+- The public native API is snapshotted as well: C++ under `scripts/cxx-api` (`yarn cxx-api-build`), and Android in `packages/react-native/ReactAndroid/api/ReactAndroid.api`. CI validates both.
+- Native modules and components are declared by JavaScript specs (`Native*.js`, `*NativeComponent.js`), from which their native counterparts are generated. Do not hand-edit generated code.
+- `CHANGELOG.md` is compiled at release time. Changelog entries belong in the pull request description.
+
+## Contributing guidelines
+
+- Keep each change focused — no unrelated refactors, formatting, or dependency updates.
+- Complete the pull request template — the motivation and the user-visible effect, and a [changelog entry](https://reactnative.dev/contributing/changelogs-in-pull-requests) with its category and type tags.
+- In the test plan, give the exact commands you ran and their results, plus screenshots or a video for user-interface changes.
+
+See [CONTRIBUTING.md](CONTRIBUTING.md) for the full process, including how to report bugs.

 # Changelog
 
+## v0.87.0
+
+### Breaking
+
+- **Appearance**: Fix return type of `useColorScheme()` hook (now  `ColorSchemeName | null`) ([ef6463c25d](https://github.com/react/react-native/commit/ef6463c25d78990386a15bb26319d1d4d224df14) by [@huntie](https://github.com/huntie))
+- **Appearance**: `useColorScheme()` no longer returns `'unspecified'` (this was always the case, but is a breaking type change) ([8ac88f481a](https://github.com/react/react-native/commit/8ac88f481a51cec28adfe985382ac7b3648921e5) by [@huntie](https://github.com/huntie))
+- **CLI**: The `react-native/core-cli-utils` package is no longer published. It remains available in the React Native repo as a reference implementation. ([9c3fddf9cd](https://github.com/react/react-native/commit/9c3fddf9cd03788a57ffca0f195bb92b84fab281) by [@huntie](https://github.com/huntie))
+- **Hermes**: Remove Legacy Hermes from C++ code ([f9476256bd](https://github.com/react/react-native/commit/f9476256bd1b5d56f46f79bb31a32e77e8e23fe6) by [@cipolleschi](https://github.com/cipolleschi))
+- **JavaScript API**: Deep imports to `'react-native/src/private/...'` have been restricted, and are no longer visible to TypeScript. These subpaths still exist, but do not have type coverage. ([142b6172a9](https://github.com/react/react-native/commit/142b6172a94ea178ed8d0fd9ffb03a64c4dd9676) by [@huntie](https://github.com/huntie))
+- **JavaScript API**: The `NativeDialogManagerAndroid` export is removed. ([a793d21a7e](https://github.com/react/react-native/commit/a793d21a7ebdea0e5a065190497a67619bdefa89) by [@huntie](https://github.com/huntie))
+- **JavaScript API**: The `Touchable` root export (undocumented) is removed. If you are extending `Touchable` as a type, please use `ViewProps` instead. ([6fbf3062f9](https://github.com/react/react-native/commit/6fbf3062f9085c93bcb35c6a61c76029abbc16a5) by [@huntie](https://github.com/huntie))
+- **JavaScript API**: `react-native/rn-get-polyfills` is removed — please use `react-native/js-polyfills` (package) ([b6a535afee](https://github.com/react/react-native/commit/b6a535afee1e099db00e62b904e3611f41227544) by [@huntie](https://github.com/huntie))
+- **Jest**: `react-native/jest-preset` is removed — all projects must now migrate to `react-native/jest-preset` (package) ([9ee21ddd9b](https://github.com/react/react-native/commit/9ee21ddd9b0d6b997709786fda4bd0b67be1ec7d) by [@huntie](https://github.com/huntie))
+- **Legacy Architecture**: Compile out RuntimeScheduler_Legacy under RCT_REMOVE_LEGACY_ARCH ([d205267a5f](https://github.com/react/react-native/commit/d205267a5fa96b343ef9860e9b2d209e5bc8832c) by [@christophpurrer](https://github.com/christophpurrer))
+- **LogBox**: Set max font scaling in `LogBox` to avoid layout breaking ([4aef2b0126](https://github.com/react/react-native/commit/4aef2b0126c22ab386c970a84d61a9ef2c4b3ddd) by [@pchalupa](https://github.com/pchalupa))
+- **Node**: Require Node.js >= 22.13.0 ([a0d39e7a9c](https://github.com/react/react-native/commit/a0d39e7a9c26446b6fe4af4ab7be00aa1c68ddca) by [@huntie](https://github.com/huntie))
+- **React Native DevTools**: Remove support for connecting to the standalone `react-devtools` package via WebSocket. Use React Native DevTools instead. ([f1971caa44](https://github.com/react/react-native/commit/f1971caa447a9d8f2f6185e99ceb45d512940e86) by [@huntie](https://github.com/huntie))

+- **Strict TypeScript API**: React Native's default JavaScript API is now the [Strict TypeScript API](https://reactnative.dev/docs/strict-typescript-api). Use `customConditions: ["react-native-legacy-deep-imports"]` to opt out. ([c948b61c05](https://github.com/react/react-native/commit/c948b61c051a2d5cfc79925e93eb49904db972c8) by [@huntie](https://github.com/huntie))

 # The React Native Ecosystem
 
-We aim to build a vibrant and inclusive ecosystem of partners, core contributors, and community that goes beyond the main React Native GitHub repository. This document explains the roles and responsibilities of various stakeholders and provides guidelines for the community organization. The structure outlined in this document has been in place for a while but had not been written down before.
+The React Native project is now part of the [React Foundation](https://react.foundation/).
 
-There are three types of stakeholders:
-
-* **Partners:** Companies significantly invested in React Native and take responsibility for the React Native vision and community.
-* **Core Contributors:** Individual people who contribute to the React Native project.
-* **Community Contributors:** Individuals who support projects in the [react-native-community](https://github.com/react-native-community) organization.
-
-## Partners
-
-Partners are companies that are significantly invested in React Native and demonstrate ownership. Informed by their use of React Native, they push for improvements of the core and/or the ecosystem around it. Examples of this may include large scale contributions to `react-native` or owning essential tools or libraries.
-
-Partners think of React Native as a product; they understand the trade offs that the project makes as well as future plans and goals. Together we shape the vision for React Native to make it the best way to build applications.
-
-### Application process
-To become a React Native partner, an existing partner needs to refer and champion your application. Partners will undergo a 3 month incubating period, after which Partners will vote to convert to full membership.
-
-Partnership is not a status symbol, it is a commitment to invest significant resources into improving React Native.
-
-Maintaining partner status requires consistently meeting the baseline responsibilities, including:
-* Attending monthly meeting.
-* Contributing to the release process.
-* Engaging in the core contributor Discord.
-
-Examples of contributing to the release include being a [community releaser](https://reactnative.dev/contributing/release-roles-responsibilities#release-role-2-community-releaser), testing new releases, and technical support for release issues.
-
-### Current partners:

-
-When you are contributing to React Native, you'll most likely meet somebody who works at one of the partner companies and who is a core contributor.
-
-## Core Contributors
-
-Core contributors are individuals who contribute to the React Native project. A core contributor is somebody who displayed a lasting commitment to the evolution and maintenance of React Native. The work done by core contributors includes responsibilities mentioned in the “Partners” section above, and concretely means that they:
-
-* Consistently contribute high quality changes, fixes and improvements
-* Actively review changes and provide quality feedback to contributors
-* Manage the release process of React Native by maintaining release branches, communicating changes to users and publishing releases
-* Love to help out other users with issues on GitHub
-* Mentor and encourage first time contributors
-* Identify React Native community members who could be effective core contributors
-* Help build an inclusive community with people from all backgrounds
-* Are great at communicating with other contributors and the community in general
-
-These are behaviors we have observed in our existing core contributors. They aren't strict rules but rather outline their usual responsibilities. We do not expect every core contributor to do all of the above things all the time. Most importantly, we want to create a supportive and friendly environment that fosters collaboration. Above all else, **we are always polite and friendly.**
-
-Core contributor status is attained after consistently contributing and taking on the responsibilities outlined above and granted by other core contributors. Similarly, after a long period of inactivity (~6 months or more), a core contributor may be contacted to understand if they’re still interested in being part of the program.
-
-You can use this [form](https://forms.gle/4jpA4QeNUvAUDnNe8) to either:
-* Apply yourself to become a Core Contributor. Make sure to include a list of valuable contributions you did to the React Native repository and ecosystem.
-* Nominate someone to become a Core Contributor.
-
-As a core contributor, you will have access to the core contributor Discord which is used for light-weight coordination and discussion.
-
-**We aim to make contributing to React Native as easy and transparent as possible.** We have discussion groups dedicated to the [new architecture rollout](https://github.com/reactwg/react-native-new-architecture), [releases](https://github.com/reactwg/react-native-releases), and [general questions and proposals](https://github.com/react-native-community/discussions-and-proposals). We are always looking for active, enthusiastic members of the React Native community to become core contributors.
-
-## Community Contributors
-
-Community contributors are individuals who support projects in the [react-native-community](https://github.com/react-native-community) organization. This organization exists as an incubator for high quality components that extend the capabilities of React Native with functionality that many but not all applications require. Meta engineers will provide guidance to help build a vibrant community of people and components that make React Native better.
-
-This structure has multiple benefits:
-
-* Keep the core of React Native small, which improves performance and reduces the surface area
-* Provide visibility to projects through shared representation, for example on the React Native website or on Twitter
-* Ensure a consistent and high standard for code, documentation, user experience, stability and contributions for third-party components
-* Upgrade the most important components right away when we make breaking changes and move the ecosystem forward at a fast pace
-* Find new maintainers for projects that are important but were abandoned by previous owners
-
-Additionally, some companies may choose to sponsor the development of one or many of the packages that are part of the community organization. They will commit to maintain projects, triage issues, fix bugs and develop features. In turn, they will be able to gain visibility for their work, for example through a mention of active maintainers in the README of individual projects after a consistent period of contributions. Such a mention may be removed if maintainers abandon the project.
-
-If you are working on a popular component and would like to move it to the React Native community, please create an issue on the [discussions-and-proposals repository](https://github.com/react-native-community/discussions-and-proposals).
+The ecosystem information previously maintained in this document has been superseded by the [React Foundation website](https://react.foundation/). Visit the website for current information about the React Native ecosystem.

-React Native brings [**React**'s][r] declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
-
-- **Declarative.** React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
-- **Component-Based.** Build encapsulated components that manage their state, then compose them to make complex UIs.
-- **Developer Velocity.** See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
-- **Portability.** Reuse code across iOS, Android, and [other platforms][p].

+React Native lets you build native apps using [React](https://react.dev/). Written
+in JavaScript, rendered with native code.
 
-## Contents
+- **Native UI.** React Native primitives render to native platform UI, meaning your app
+  uses the same native platform APIs other apps do. Gestures, text scaling, and
+  accessibility behave the way users expect on each OS.
+- **React, everywhere.** Declarative UI, components, hooks, and Suspense, reused
+  across Android, iOS, and [other platforms](https://reactnative.dev/docs/out-of-tree-platforms).
+- **Developer Velocity.** See local changes in seconds. Changes to JavaScript code are applied with Fast Refresh, without rebuilding the native app.
+- **Extend it yourself.** Native Modules let you call platform code directly from JavaScript, synchronously and type-safe — or reach for [thousands of existing libraries](https://reactnative.directory/).

+React Native is developed and supported by many companies and individual core contributors. Find out more on the [React Foundation website](https://react.foundation/).
 
+## Building your first React Native app
 
-## 📋 Requirements
+Follow the [Getting Started guide](https://reactnative.dev/docs/environment-setup) for a new app, or [Integration with Existing Apps](https://reactnative.dev/docs/integration-with-existing-apps) to adopt React Native incrementally.
 
-React Native apps may target iOS 15.1 and Android 7.0 (API 24) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like [Expo](https://expo.dev) can be used to work around this.
+### Using a Framework
 
-## 🎉 Building your first React Native app
+We believe that the best way to experience React Native is through a Framework, a toolbox with all the necessary APIs to let you build production ready apps. [Expo](https://docs.expo.dev/get-started/set-up-your-environment/) is a production-grade React Native Framework, with file-based routing, a standard library of native modules, and much more.
 
-Follow the [Getting Started guide](https://reactnative.dev/docs/getting-started). The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
+To create a new Expo project, run the following in your terminal:
 
-- [Trying out React Native][hello-world]
-- [Creating a New Application][new-app]
-- [Adding React Native to an Existing Application][existing]
+    npx create-expo-app@latest
 
-[hello-world]: https://snack.expo.dev/@samples/hello-world
-[new-app]: https://reactnative.dev/docs/getting-started
-[existing]: https://reactnative.dev/docs/integration-with-existing-apps
+Then follow the rest of [Expo's getting started guide](https://docs.expo.dev/get-started/set-up-your-environment/) to start building.
 
-## 📖 Documentation
+### Without a Framework
 
-The full documentation for React Native can be found on our [website][docs].
+You can also use React Native without a Framework, however we've found that most developers benefit from one — navigation, native dependencies, and platform tooling are problems the ecosystem has already solved. If a Framework doesn't suit your app, follow [Getting Started Without a Framework](https://reactnative.dev/docs/getting-started-without-a-framework).
 
-The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the [React documentation][r-docs].
+## Documentation
 
-The source for the React Native documentation and website is hosted on a separate repository, [**@facebook/react-native-website**][repo-website].

+Android resource-path helpers used when copying React Native assets into `drawable-*` / `raw` folders. Consumed by bundling and build tooling; most apps never import this directly.

+
+| Export | Signature | Notes |
+|---|---|---|
+| `getAndroidResourceFolderName` | `(asset: PackagerAsset, scale: number) => string` | e.g. `drawable-xhdpi`; non-drawable types resolve to `raw` |
+| `getAndroidResourceIdentifier` | `(asset: PackagerAsset) => string` | Sanitised resource name |
+| `drawableFileTypes` | `Set<string>` | Asset types that map to a `drawable-*` folder |

-## Installation
+> [!Warning]
+> **This package is deprecated (since 0.87)** and will be removed in a future release. Use [`AssetRegistry`](https://reactnative.dev/docs/assetregistry) from `react-native` (or the `react-native/asset-registry` build entry point) instead of `@react-native/assets-registry/registry`, and [`@react-native/asset-utils`](https://www.npmjs.com/package/@react-native/asset-utils) instead of `@react-native/assets-registry/path-support`.
 
-```
-yarn add --dev @react-native/assets-registry
-```
+Runtime registry that maps asset IDs generated in a Metro bundle to asset metadata. It backs `<Image>`, `Image.resolveAssetSource()`, and any code that resolves `require('./img.png')` on native.
 
-*Note: We're using `yarn` to install deps. Feel free to change commands to use `npm` 3+ and `npx` if you like*
+Most apps never import this directly — assets are handled through `<Image>`.

-1. `yarn` to install the dependencies. You just need to run this once
-2. `yarn jest packages/assets-registry`.
+| Export | Signature | Notes |
+|---|---|---|
+| `registerAsset` | `(asset: PackagerAsset) => number` | Stores the asset; returns a numeric ID |

+Android resource-path helpers, used when copying assets into `drawable-*` folders.
+
+| Export | Signature | Notes |
+|---|---|---|
+| `getAndroidResourceFolderName` | `(asset: PackagerAsset, scale: number) => string` | e.g. `drawable-xhdpi`; non-drawable types resolve to `raw` |
+| `getAndroidResourceIdentifier` | `(asset: PackagerAsset) => string` | Sanitised resource name |
+| `getBasePath` | `(asset: PackagerAsset) => string` | `httpServerLocation` without the leading slash |

-### Migration Note
-
-This Jest preset used to be part of the core `react-native` package and accessible at `react-native/jest-preset.js`. As long as `@react-native/jest-preset` is installed, `react-native/jest-preset.js` will be aliased to this package and continue to work but is deprecated.
-
-Follow the installation instructions above to migrate to `@react-native/jest-preset` and change `preset: 'react-native'` to `preset: '@react-native/jest-preset` to migrate.

+ * This is a purely lexical judgement - we never touch the filesystem, and we
+ * never resolve the platform-specific implementation (Platform.ios.js,
+ * Platform.android.js). Metro does that later; the identity we care about here
+ * is the extension-less module `<rn-root>/Libraries/Utilities/Platform`.
+ *
+ * `filename` may be absolute or project-root-relative: Metro passes
+ * `path.relative(projectRoot, filePath)`, while Babel callers generally pass an
+ * absolute path. Both work, because everything below is relative arithmetic on
+ * the importer's own path. It does mean a relative importer path is interpreted
+ * as being rooted at the project root, so this assumes the project root is not
+ * itself inside the react-native package - true for any real app, and for RN's
+ * own repo, where the project root is the monorepo root.
+ *
+ * The React Native package root is identified by its directory name, which
+ * holds for every layout we need to support:
+ *
+ *   node_modules/react-native/...
+ *   packages/react-native/...
+ *   node_modules/.pnpm/react-native@x.y.z/node_modules/react-native/...
+ *
+ * We deliberately do not accept a path that merely ends in
+ * `Libraries/Utilities/Platform`: an app with its own module of that name must
+ * not be inlined.

+ * Renders a boolean input.
+ *
+ * This is a controlled component that requires an `onValueChange` callback
+ * that updates the `value` prop in order for the component to reflect user
+ * actions. If the `value` prop is not updated, the component will continue to
+ * render the supplied `value` prop instead of the expected result of any user
+ * actions.
+ *
+ * Example:
+ *
+ * ```tsx
+ * import React, {useState} from 'react';
+ * import {View, Switch, StyleSheet} from 'react-native';
+ *
+ * const App = () => {
+ *   const [isEnabled, setIsEnabled] = useState(false);
+ *   const toggleSwitch = () => setIsEnabled(previousState => !previousState);
+ *
+ *   return (
+ *     <View style={styles.container}>
+ *       <Switch
+ *         trackColor={{false: '#767577', true: '#81b0ff'}}

-/**
- * A foundational component for inputting text into the app via a
- * keyboard. Props provide configurability for several features, such as
- * auto-correction, auto-capitalization, placeholder text, and different keyboard
- * types, such as a numeric keypad.
- *
- * The simplest use case is to plop down a `TextInput` and subscribe to the
- * `onChangeText` events to read the user input. There are also other events,
- * such as `onSubmitEditing` and `onFocus` that can be subscribed to. A simple
- * example:
- *
- * ```ReactNativeWebPlayer
- * import React, { Component } from 'react';
- * import { AppRegistry, TextInput } from 'react-native';
- *
- * export default class UselessTextInput extends Component {
- *   constructor(props) {
- *     super(props);
- *     this.state = { text: 'Useless Placeholder' };
- *   }
- *
- *   render() {
- *     return (
- *       <TextInput
- *         style={{height: 40, borderColor: 'gray', borderWidth: 1}}
- *         onChangeText={(text) => this.setState({text})}
- *         value={this.state.text}
- *       />
- *     );
- *   }
- * }
- *
- * // skip this line if using Create React Native App
- * AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
- * ```
- *
- * Two methods exposed via the native element are .focus() and .blur() that
- * will focus or blur the TextInput programmatically.
- *
- * Note that some props are only available with `multiline={true/false}`.
- * Additionally, border styles that apply to only one side of the element
- * (e.g., `borderBottomColor`, `borderLeftWidth`, etc.) will not be applied if
- * `multiline=false`. To achieve the same effect, you can wrap your `TextInput`
- * in a `View`:
- *
- * ```ReactNativeWebPlayer
- * import React, { Component } from 'react';
- * import { AppRegistry, View, TextInput } from 'react-native';
- *
- * class UselessTextInput extends Component {
- *   render() {
- *     return (
- *       <TextInput
- *         {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
- *         editable={true}
- *         maxLength={40}
- *       />
- *     );
- *   }
- * }
- *
- * export default class UselessTextInputMultiline extends Component {
- *   constructor(props) {
- *     super(props);
- *     this.state = {
- *       text: 'Useless Multiline Placeholder',
- *     };
- *   }
- *
- *   // If you type something in the text box that is a color, the background will change to that
- *   // color.
- *   render() {
- *     return (
- *      <View style={{
- *        backgroundColor: this.state.text,
- *        borderBottomColor: '#000000',
- *        borderBottomWidth: 1 }}
- *      >
- *        <UselessTextInput
- *          multiline={true}
- *          numberOfLines={4}
- *          onChangeText={(text) => this.setState({text})}
- *          value={this.state.text}
- *        />
- *      </View>
- *     );
- *   }
- * }
- *
- * // skip these lines if using Create React Native App
- * AppRegistry.registerComponent(
- *  'AwesomeProject',
- *  () => UselessTextInputMultiline
- * );
- * ```
- *
- * `TextInput` has by default a border at the bottom of its view. This border
- * has its padding set by the background image provided by the system, and it
- * cannot be changed. Solutions to avoid this is to either not set height
- * explicitly, case in which the system will take care of displaying the border
- * in the correct position, or to not display the border by setting
- * `underlineColorAndroid` to transparent.
- *
- * Note that on Android performing text selection in input can change

+/**
+ * A foundational component for inputting text into the app via a
+ * keyboard. Props provide configurability for several features, such as
+ * auto-correction, auto-capitalization, placeholder text, and different keyboard
+ * types, such as a numeric keypad.
+ *
+ * The simplest use case is to plop down a `TextInput` and subscribe to the
+ * `onChangeText` events to read the user input. There are also other events,
+ * such as `onSubmitEditing` and `onFocus` that can be subscribed to.
+ *
+ * Example:
+ *
+ * ```tsx
+ * import React, { Component } from 'react';
+ * import { AppRegistry, TextInput } from 'react-native';
+ *
+ * export default class UselessTextInput extends Component {
+ *   constructor(props) {
+ *     super(props);
+ *     this.state = { text: 'Useless Placeholder' };
+ *   }
+ *
+ *   render() {
+ *     return (
+ *       <TextInput
+ *         style={{height: 40, borderColor: 'gray', borderWidth: 1}}
+ *         onChangeText={(text) => this.setState({text})}
+ *         value={this.state.text}
+ *       />
+ *     );
+ *   }
+ * }
+ *
+ * // skip this line if using Create React Native App
+ * AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
+ * ```
+ *
+ * Two methods exposed via the native element are .focus() and .blur() that
+ * will focus or blur the TextInput programmatically.
+ *
+ * Note that some props are only available with `multiline={true/false}`.
+ * Additionally, border styles that apply to only one side of the element
+ * (e.g., `borderBottomColor`, `borderLeftWidth`, etc.) will not be applied if
+ * `multiline=false`. To achieve the same effect, you can wrap your `TextInput`
+ * in a `View`:
+ *
+ * Example:
+ *
+ * ```tsx
+ * import React, { Component } from 'react';
+ * import { AppRegistry, View, TextInput } from 'react-native';
+ *
+ * class UselessTextInput extends Component {
+ *   render() {
+ *     return (
+ *       <TextInput
+ *         {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
+ *         editable={true}
+ *         maxLength={40}
+ *       />
+ *     );
+ *   }
+ * }
+ *
+ * export default class UselessTextInputMultiline extends Component {
+ *   constructor(props) {
+ *     super(props);
+ *     this.state = {
+ *       text: 'Useless Multiline Placeholder',
+ *     };
+ *   }
+ *
+ *   // If you type something in the text box that is a color, the background will change to that
+ *   // color.
+ *   render() {
+ *     return (
+ *      <View style={{
+ *        backgroundColor: this.state.text,
+ *        borderBottomColor: '#000000',
+ *        borderBottomWidth: 1 }}
+ *      >
+ *        <UselessTextInput
+ *          multiline={true}
+ *          numberOfLines={4}
+ *          onChangeText={(text) => this.setState({text})}
+ *          value={this.state.text}
+ *        />
+ *      </View>
+ *     );
+ *   }
+ * }
+ *
+ * // skip these lines if using Create React Native App
+ * AppRegistry.registerComponent(
+ *  'AwesomeProject',
+ *  () => UselessTextInputMultiline
+ * );
+ * ```
+ *
+ * `TextInput` has by default a border at the bottom of its view. This border
+ * has its padding set by the background image provided by the system, and it
+ * cannot be changed. Solutions to avoid this is to either not set height
+ * explicitly, case in which the system will take care of displaying the border
+ * in the correct position, or to not display the border by setting
+ * `underlineColorAndroid` to transparent.
+ *
+ * Note that on Android performing text selection in input can change
+ * app's activity `windowSoftInputMode` param to `adjustResize`.
+ * This may cause issues with components that have position: 'absolute'
+ * while keyboard is active. To avoid this behavior either specify `windowSoftInputMode`
+ * in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html )
+ * or control this param programmatically with native code.
+ *

-/**
- * `Touchable`: Taps done right.
- *
- * You hook your `ResponderEventPlugin` events into `Touchable`. `Touchable`
- * will measure time/geometry and tells you when to give feedback to the user.
- *
- * ====================== Touchable Tutorial ===============================
- * The `Touchable` mixin helps you handle the "press" interaction. It analyzes
- * the geometry of elements, and observes when another responder (scroll view
- * etc) has stolen the touch lock. It notifies your component when it should
- * give feedback to the user. (bouncing/highlighting/unhighlighting).
- *
- * - When a touch was activated (typically you highlight)
- * - When a touch was deactivated (typically you unhighlight)
- * - When a touch was "pressed" - a touch ended while still within the geometry
- *   of the element, and no other element (like scroller) has "stolen" touch
- *   lock ("responder") (Typically you bounce the element).
- *
- * A good tap interaction isn't as simple as you might think. There should be a
- * slight delay before showing a highlight when starting a touch. If a
- * subsequent touch move exceeds the boundary of the element, it should
- * unhighlight, but if that same touch is brought back within the boundary, it
- * should rehighlight again. A touch can move in and out of that boundary
- * several times, each time toggling highlighting, but a "press" is only
- * triggered if that touch ends while within the element's boundary and no
- * scroller (or anything else) has stolen the lock on touches.
- *
- * To create a new type of component that handles interaction using the
- * `Touchable` mixin, do the following:
- *
- * - Initialize the `Touchable` state.
- *
- *   getInitialState: function() {
- *     return merge(this.touchableGetInitialState(), yourComponentState);
- *   }
- *
- * - Choose the rendered component who's touches should start the interactive
- *   sequence. On that rendered node, forward all `Touchable` responder
- *   handlers. You can choose any rendered node you like. Choose a node whose
- *   hit target you'd like to instigate the interaction sequence:
- *
- *   // In render function:
- *   return (
- *     <View
- *       onStartShouldSetResponder={this.touchableHandleStartShouldSetResponder}
- *       onResponderTerminationRequest={this.touchableHandleResponderTerminationRequest}
- *       onResponderGrant={this.touchableHandleResponderGrant}
- *       onResponderMove={this.touchableHandleResponderMove}
- *       onResponderRelease={this.touchableHandleResponderRelease}
- *       onResponderTerminate={this.touchableHandleResponderTerminate}>
- *       <View>
- *         Even though the hit detection/interactions are triggered by the
- *         wrapping (typically larger) node, we usually end up implementing
- *         custom logic that highlights this inner one.
- *       </View>
- *     </View>
- *   );
- *
- * - You may set up your own handlers for each of these events, so long as you
- *   also invoke the `touchable*` handlers inside of your custom handler.
- *
- * - Implement the handlers on your component class in order to provide
- *   feedback to the user. See documentation for each of these class methods
- *   that you should implement.
- *
- *   touchableHandlePress: function() {
- *      this.performBounceAnimation();  // or whatever you want to do.
- *   },
- *   touchableHandleActivePressIn: function() {
- *     this.beginHighlighting(...);  // Whatever you like to convey activation
- *   },
- *   touchableHandleActivePressOut: function() {
- *     this.endHighlighting(...);  // Whatever you like to convey deactivation

- * A wrapper for making views respond properly to touches.

+//
+// Mechanism:
+//
+// 1. Step 1 resizes the container wrapping the row. The row's content-determined
+//    size does not change, so Yoga re-MEASURES the row subtree with new
+//    constraints (a measure-only pass: `zeroOutLayoutRecursively` wipes the
+//    `display: none` child and sets `hasNewLayout` on it) but restores the row's
+//    final layout from cache. RN's metrics traversal never visits the centered
+//    wrapper, so the `hasNewLayout` flag on the hidden child is never consumed --
+//    it leaks across the commit.
+//
+// 2. Step 2 changes only the TextInput's props. Fabric clones the row with a new
+//    children list; `adoptYogaChild` clones the untouched centered wrapper via
+//    `clone({})`, which SHARES the hidden child's yoga node (stale
+//    `hasNewLayout`, owner = previous generation's wrapper). During layout the
+//    wrapper is a clean cache hit, so `cloneChildrenIfNeeded()` never repairs
+//    ownership -- yet `calculateLayoutInternal` still flags the wrapper with
+//    `hasNewLayout`. RN's traversal then descends into the wrapper, finds the
+//    shared hidden child flagged but owned by the old generation, and trips the
+//    assert.
+//
+// The KeyboardAvoidingView + focus/typing path reproduces the same sequence
+// organically (keyboard resize = step 1, restyle-on-change = step 2). If Yoga
+// aborts, `runTask` re-throws the native error synchronously and this test fails.

-/**
- * `PanResponder` reconciles several touches into a single gesture. It makes
- * single-touch gestures resilient to extra touches, and can be used to
- * recognize simple multi-touch gestures.
- *
- * It provides a predictable wrapper of the responder handlers provided by the
- * [gesture responder system](docs/gesture-responder-system.html).
- * For each handler, it provides a new `gestureState` object alongside the
- * native event object:
- *
- * ```
- * onPanResponderMove: (event, gestureState) => {}
- * ```
- *
- * A native event is a synthetic touch event with the following form:
- *
- *  - `nativeEvent`
- *      + `changedTouches` - Array of all touch events that have changed since the last event
- *      + `identifier` - The ID of the touch
- *      + `locationX` - The X position of the touch, relative to the element
- *      + `locationY` - The Y position of the touch, relative to the element
- *      + `pageX` - The X position of the touch, relative to the root element
- *      + `pageY` - The Y position of the touch, relative to the root element
- *      + `target` - The node id of the element receiving the touch event
- *      + `timestamp` - A time identifier for the touch, useful for velocity calculation
- *      + `touches` - Array of all current touches on the screen
- *
- * A `gestureState` object has the following:
- *
- *  - `stateID` - ID of the gestureState- persisted as long as there at least
- *     one touch on screen
- *  - `moveX` - the latest screen coordinates of the recently-moved touch
- *  - `moveY` - the latest screen coordinates of the recently-moved touch
- *  - `x0` - the screen coordinates of the responder grant
- *  - `y0` - the screen coordinates of the responder grant
- *  - `dx` - accumulated distance of the gesture since the touch started
- *  - `dy` - accumulated distance of the gesture since the touch started
- *  - `vx` - current velocity of the gesture
- *  - `vy` - current velocity of the gesture
- *  - `numberActiveTouches` - Number of touches currently on screen
- *
- * ### Basic Usage
- *
- * ```

- *     this._panResponder = PanResponder.create({

- *
- *         // The accumulated gesture distance since becoming responder is
- *         // gestureState.d{x,y}
- *       },
- *       onPanResponderTerminationRequest: (evt, gestureState) => true,
- *       onPanResponderRelease: (evt, gestureState) => {
- *         // The user has released all touches while this view is the
- *         // responder. This typically means a gesture has succeeded
- *       },
- *       onPanResponderTerminate: (evt, gestureState) => {
- *         // Another component has become the responder, so this gesture

+ * A styling abstraction for React Native, inspired by CSS stylesheets.
+ *
+ * Use `StyleSheet.create()` to define a group of named styles in one place,
+ * separate from your render logic. The styles are plain objects, so the call
+ * is effectively an identity function — its main benefit is static type
+ * checking of each style against the valid native style properties for a
+ * `View`, `Text`, or `Image`. Naming styles and moving them out of the render
+ * tree also keeps components easier to read.
+ *
+ * Example:
+ *
+ * ```tsx
+ * const styles = StyleSheet.create({
+ *   container: {
+ *     flex: 1,
+ *     padding: 24,
+ *   },
+ *   title: {
+ *     fontSize: 20,
+ *     fontWeight: '600',
+ *   },
+ * });
+ *
+ * function Screen() {
+ *   return (
+ *     <View style={styles.container}>
+ *       <Text style={styles.title}>Hello</Text>
+ *     </View>
+ *   );
+ * }
+ * ```
+ *
+ * The module also provides helpers for combining styles — `compose` (merge
+ * two styles, with the second overriding the first) and `flatten` (collapse
+ * an array of styles into a single object) — plus the constants `absoluteFill`,
+ * `absoluteFillObject`, and `hairlineWidth` for common layout patterns.

+ * under
+ * `ReactAndroid/src/test/java/com/facebook/react/fabric/FabricMountingManagerInstrumentationTest`.
+ *
+ * These tests focus on the small, JNI-free slice of the public API:
+ *   - `onSurfaceStart`  — populates the allocated-view registry for a new
+ *                         surface.
+ *   - `onSurfaceStop`   — removes the registry entry for a surface.
+ *   - `isViewAllocated` — returns whether a `(surfaceId, tag)` pair is
+ *                         registered.
+ *
+ * These three methods only touch in-memory state guarded by
+ * `allocatedViewsMutex_`; they never call into Java. That is what makes them
+ * unit-testable here.
+ *
+ * `react/fabric:jni` is an Android-only native library, so this target is
+ * built as a JNI instrumentation test: the gtest binary is packaged into an
+ * APK and executed on a device/emulator. A JavaVM is therefore attached, which
+ * `~FabricMountingManager()` requires — it calls
+ * `jni::ThreadScope::WithClassLoader`, which throws `std::runtime_error` when
+ * fbjni has not been initialized (see
+ * `xplat/spectrum/androidLibs/fbjni/cxx/fbjni/detail/Environment.h`).

+ * `alias_ref<JCollection<...>>` is a null reference, the function must
+ * short-circuit and return an empty vector rather than dereferencing the
+ * null collection. `alias_ref` is default-constructible to a null state

+ * path that leaves `javaModules` unset (for example, new-architecture
+ * bring-up paths that legitimately pass no legacy Java modules). Because
+ * the crash would only surface once the process actually reaches this

 #### 4. Update the rendering
 
-The last step is to check if the previous work produced any rendering updates
-(transactions produced by commits in React, or view commands being dispatched).
-If that is the case, it notifies the host platform that it should apply the
-necessary mutations to reach that state.
-
-In the future, this step could be extended to do more of the work that browsers
-do. For example, it could run resize observations and run resize observer
-callbacks, or update animations and run animation frame callbacks.
+The last step applies work that browsers perform after task and microtask
+execution, before the next task is selected (see
+[HTML — update the rendering](https://html.spec.whatwg.org/multipage/webappapis.html#update-the-rendering)).
+
+In [`RuntimeScheduler_Modern`](../RuntimeScheduler_Modern.h), this step
+currently:
+
+1. Dispatches pending Event Timing entries (when enabled).
+2. Runs
+   [Resize Observer](https://drafts.csswg.org/resize-observer/#broadcast-resize-notifications-h)
+   observations via
+   `RuntimeSchedulerResizeObserverDelegate::runResizeObservations()`. See the
+   [ResizeObserver API](../../../../../src/private/webapis/resizeobserver/__docs__/README.md).
+3. Updates [Intersection Observer](https://www.w3.org/TR/intersection-observer/)
+   observations via `RuntimeSchedulerIntersectionObserverDelegate`.
+4. Drains pending rendering updates (commits, view commands) so the host
+   platform can apply mutations.
+
+Observer steps run before the rendering-update queue is drained. Resize and
+intersection observer integration is only implemented in
+`RuntimeScheduler_Modern`; `RuntimeScheduler_Legacy` treats the corresponding
+delegates as no-ops.
+
+Additional browser work in this phase (e.g. animation frame callbacks) may be
+added in the future.

+# Prebuilt ReactNativeDependencies — self-serving headers + deps facades
+
+How the third-party C/C++ deps (`RCT-Folly`, `glog`, `boost`,
+`DoubleConversion`, `fmt`, `fast_float`, `SocketRocket`) are served when
+`ReactNativeDependenciesUtils.build_react_native_deps_from_source()` is false
+(prebuilt-deps mode). Source-deps mode is unaffected by everything below.
+
+## Pod-served headers, CocoaPods only (`rndependencies.rb`)
+
+In prebuilt-deps mode the `ReactNativeDependencies` POD (CocoaPods) is the
+single authority for the third-party deps: compiled code lives in its
+xcframework binary, and the artifact's own
+`Headers/{folly,glog,boost,fmt,double-conversion,fast_float,SocketRocket}` are
+flattened into the pod's `Headers/` by the podspec's `prepare_command`.
+Consumers resolve bare `<folly/...>` / `<SocketRocket/...>` via CocoaPods
+public-header linkage from `s.dependency "ReactNativeDependencies"`, plus
+`HEADER_SEARCH_PATHS` entries pointing at
+`$(PODS_ROOT)/ReactNativeDependencies/Headers`: per-podspec via
+`add_rn_third_party_dependencies`, and globally (aggregate + every pod target)
+via `ReactNativeDependenciesUtils.configure_aggregate_xcconfig` at post-install
+— ReactNativeHeaders is pure-RN, so this is the only global home of the deps
+namespaces. The real source pods are neither depended on nor searched.
+
+For SPM, the deps XCFRAMEWORK itself cannot serve headers: it is framework-type
+without `HeadersPath`, and its root `Headers/` is invisible to SPM binaryTargets
+(verified 2026-07-04 — `HeadersPath` is rejected on framework entries). The deps
+prebuild therefore emits a headers-only LIBRARY-type sidecar,
+`ReactNativeDependenciesHeaders.xcframework` (same recipe as ReactNativeHeaders:
+stub archives + per-slice `Headers/`), which SPM auto-serves with zero flags.
+The sidecar ships inside the deps tarball and as a standalone artifact.
+
+## Why SocketRocket is vended here
+
+React-Core compiled from source (source-core + prebuilt-deps mix) imports
+`<SocketRocket/SRWebSocket.h>` (`RCTReconnectingWebSocket.m`), and in
+prebuilt-deps mode there is NO real SocketRocket pod in the graph — the artifact
+is the sole supplier. This does not reintroduce the 2026-07-03 dual-copy
+regression: that bug relocated SocketRocket copies onto every pod's search path
+(via ReactNativeHeaders → React-Core-prebuilt) while a REAL SocketRocket pod
+coexisted. Here there is exactly one physical copy and no coexisting pod.
+
+## Deps facades (`rndeps_facades.rb`, declared in `react_native_pods.rb`)
+
+The real source pods are only declared in the deps-from-source branch, so in
+prebuilt-deps mode a community podspec's hardcoded `s.dependency "RCT-Folly"` /
+`"RCT-Folly/Fabric"` / `"glog"` would resolve from the CocoaPods trunk and
+compile from source next to the prebuilt binary. `RNDepsFacades` generates
+dependency-only facade podspecs (`build/rndeps-facades/<Name>/`), installed as
+LOCAL pods (`:path`, so Podfile-local resolution beats trunk, nothing fetched):
+no sources, no headers, single dependency on `ReactNativeDependencies`.
+Versions + subspecs are DERIVED from the real podspecs in
+`third-party-podspecs/` (RCT-Folly keeps `/Default` + `/Fabric`,
+`default_subspecs = ["Default"]`). SocketRocket has no local podspec — its
+facade version is SYNTHESIZED from
+`Helpers::Constants::socket_rocket_config[:version]`, fail-closed if absent.
+`:modular_headers` is intentionally dropped on facade declarations: a
+dependency-only placeholder builds no module; consumers get modules from
+`ReactNativeDependencies`.
+
+## Mode × supplier table
+
+| core × deps         | real 3P pods in graph                           | SocketRocket headers supplier   |
+| ------------------- | ----------------------------------------------- | ------------------------------- |
+| source + source     | yes (`react_native_pods.rb` deps-source branch) | real pod                        |
+| source + prebuilt   | no                                              | RNDeps artifact (sole supplier) |
+| prebuilt + source   | yes                                             | real pod                        |
+| prebuilt + prebuilt | no                                              | RNDeps artifact                 |
+
+## SocketRocket privacy manifest
+
+Upstream SocketRocket ships NO privacy manifest, and the deps artifact
+historically carried bundles only for boost/folly/glog. Fixed alongside this
+work: the deps prebuild (`scripts/releases/ios-prebuild/configuration.js`) now
+embeds `ReactNativeDependencies_SocketRocket.bundle/PrivacyInfo.xcprivacy`,
+sourced from an RN-authored manifest at
+`scripts/releases/ios-prebuild/resources/SocketRocket/PrivacyInfo.xcprivacy`
+(accurate-empty: SocketRocket uses no Required Reason APIs). Facades remain
+resource-free by design.

+# Facade podspecs for the prebuilt React Native Core path.
+#
+# In prebuilt mode the compiled code AND headers for the React core pods live
+# entirely inside React.xcframework + React-Core-prebuilt (which flattens the
+# ReactNativeHeaders namespaces into its Headers/). Re-installing the SOURCE
+# podspecs in that mode is what makes them ship duplicate headers that shadow the
+# prebuilt artifact (via HEADER_SEARCH_PATHS, CocoaPods .hmap header maps, and
+# the all-product-headers VFS overlay) and break the React framework's clang
+# explicit-module precompile.
+#
+# Instead we install dependency-only FACADE podspecs for those names: they ship
+# no source files and (with one narrow exception, see FACADE_REEXPOSED_HEADERS)
+# no headers, so CocoaPods makes them PBXAggregateTarget
+# placeholders (should_build? == false) and nothing is laid down to shadow. Each
+# facade depends on React-Core-prebuilt so its consumers transitively pick up the
+# prebuilt framework + headers. The pod NAMES still resolve, so ReactCodegen,
+# third-party modules, and RN's own podspec graph keep resolving `React-Core`,
+# `Yoga`, `React-Core/Default`, etc.
+#
+# MAINTENANCE MODEL: the set of facaded pods is explicit (FACADE_PODS) so the
+# prebuilt rollout can be staged, but each facade's VERSION and SUBSPECS are
+# DERIVED from the real podspec at `pod install` time (Pod::Specification.from_file).
+# That removes the drift risk that would otherwise bite third-party libraries:
+# if React adds/renames `React-Core/<Subspec>`, the facade exposes it
+# automatically — nobody has to hand-maintain a parallel subspec list.
+#
+# This is staged: phase 1 facades a small set and KEEPS the existing
+# podspec_sources / add_rncore_dependency / configure_aggregate_xcconfig /
+# -fmodule-map-file machinery. The set is expanded until the cold prebuilt
+# build passes; the distributed prebuilt helpers are only deleted afterwards.

@@ -111,123 +111,54 @@ The build process uses specific `xcodebuild` flags:
 - Build times vary depending on the target platform and configuration
 - XCFrameworks support multiple architectures in a single bundle
 
-## Known Issues
-
-The generated XCFrameworks currently use CocoaPods-style header structures
-rather than standard framework header conventions. This may cause modularity
-issues when:
-
-- Consuming the XCFrameworks in projects that expect standard framework headers
-- Building dependent frameworks that rely on proper module boundaries
-- Integrating with Swift Package Manager projects expecting modular headers
-
-## VFS Overlay System
-
-The prebuilt XCFrameworks use Clang's Virtual File System (VFS) overlay
-mechanism to enable header imports without modifying the actual header file
-structure. This is necessary because React Native's headers are organized
-differently than standard framework conventions.
-
-### Overview
-
-The VFS overlay creates a virtual mapping between the import paths used in code
-(e.g., `#import <react/renderer/graphics/Size.h>`) and the actual physical
-locations of headers within the XCFramework. This allows the prebuilt frameworks
-to work seamlessly while maintaining the original import syntax.
-
-### Build-Time VFS Generation (`vfs.js`)
-
-The `vfs.js` script creates a VFS overlay template during the prebuild process:
-
-1. **Header Collection** (`headers.js`): Scans all podspec files in the React
-   Native package to discover header files and their target import paths.
-
-2. **VFS Structure Building**: The `buildVFSStructure()` function creates a
-   hierarchical directory tree representation from the header mappings. Clang's
-   VFS overlay requires directories to contain their children in a tree
-   structure.
-
-3. **YAML Generation**: The `generateVFSOverlayYAML()` function converts the VFS
-   structure into Clang's expected YAML format.
-
-4. **Template Creation**: The generated overlay uses `${ROOT_PATH}` as a
-   placeholder for the actual installation path. This template is included in
-   the XCFramework as `React-VFS-template.yaml`.
-
-#### Key Functions
-
-- `createVFSOverlay(rootFolder)`: Main entry point that generates the complete
-  VFS overlay YAML string
-- `createVFSOverlayContents(rootFolder)`: Creates the VFS overlay object
-  structure
-- `buildVFSStructure(mappings)`: Builds the hierarchical directory tree from
-  flat mappings
-- `resolveVFSOverlay(vfsTemplate, rootPath)`: Replaces `${ROOT_PATH}` with the
-  actual path
-
-### Runtime VFS Processing (CocoaPods)
-
-When consuming prebuilt frameworks via CocoaPods, the VFS overlay is processed
-at pod install time by `rncore.rb`:
-
-#### `process_vfs_overlay()`
-
-Called during `react_native_post_install`, this method:
-
-1. Reads the `React-VFS-template.yaml` from the XCFramework
-2. Resolves the `${ROOT_PATH}` placeholder with the actual XCFramework path
-3. Writes the resolved overlay to
-   `$(PODS_ROOT)/React-Core-prebuilt/React-VFS.yaml`
-
-#### `add_rncore_dependency(s)`
-
-Adds VFS overlay compiler flags to podspecs that depend on React Native:
-
-```ruby
-# For C/C++ compilation
-OTHER_CFLAGS += "-ivfsoverlay $(PODS_ROOT)/React-Core-prebuilt/React-VFS.yaml"
-OTHER_CPLUSPLUSFLAGS += "-ivfsoverlay $(PODS_ROOT)/React-Core-prebuilt/React-VFS.yaml"
-
-# For Swift compilation (flags passed to underlying Clang)
-OTHER_SWIFT_FLAGS += "-Xcc -ivfsoverlay -Xcc $(PODS_ROOT)/React-Core-prebuilt/React-VFS.yaml"
-```
-
-#### `configure_aggregate_xcconfig(installer)`
-
-Configures VFS overlay flags for:
-
-- **Aggregate targets**: Main app targets that don't go through podspec
-  processing
-- **All pod targets**: Third-party pods that don't explicitly call
-  `add_rncore_dependency`
-
-This ensures all compilation units in the project can resolve React Native
-headers through the VFS overlay.
-
-### VFS Overlay Format
-
-The VFS overlay uses Clang's hierarchical YAML format:
-
-```yaml
-version: 0
-case-sensitive: false
-roots:
-  - name: '${ROOT_PATH}/Headers'
-    type: 'directory'
-    contents:
-      - name: 'react'
-        type: 'directory'
-        contents:
-          - name: 'renderer'
-            type: 'directory'
-            contents:
-              - name: 'Size.h'
-                type: 'file'
-                external-contents: '${ROOT_PATH}/Headers/React/react/renderer/Size.h'
-```
-
-The structure maps virtual paths (what the compiler sees) to physical paths
-(where the files actually exist in the XCFramework).
+## Header Resolution (headers-spec layout)
+
+The prebuilt XCFrameworks ship a **headers-spec layout** so that header imports
+resolve through plain header/framework search paths — there is **no clang VFS
+overlay**. The layout contract is defined and validated in code:
+
+- `headers-spec.js`: the executable layout contract (rules R1–R8) — which
+  namespaces are hoisted, which carry module maps, and how collisions are
+  rejected.
+- `headers-inventory.js`: scans the source tree to build the live header
+  inventory that feeds the spec.
+- `headers-compose.js`: emits the layout. `emitReactFrameworkHeaders()` writes
+  the `React/` and bare-aliased headers into every slice's
+  `React.framework/Headers`, and `buildReactNativeHeadersXcframework()`
+  assembles the headers-only `ReactNativeHeaders.xcframework` carrying every
+  other namespace (incl. `react/`) plus the third-party dependency namespaces
+  (`folly`, `glog`, `boost`, `fmt`, `double-conversion`, `fast_float`). The
+  Hermes public headers (`<hermes/...>`) are folded in only on the SwiftPM
+  consumer side (`ensureHeadersLayout`); the published prebuild artifact does
+  not yet carry them (TODO in `xcframework.js`).
+
+### Artifacts
+
+The prebuild (`xcframework.js`) always produces:
+
+- `React.xcframework` — the compiled React core. Each slice's `React.framework`
+  carries the headers-spec layout (every `<React/...>` header + the framework
+  module map). CocoaPods consumes that layout directly, through
+  `FRAMEWORK_SEARCH_PATHS`. SwiftPM consumes the same headers indirectly: the
+  XCFramework is not a member of the Swift package graph, so the consumer side
+  stages a copy of `React.framework/Headers` into
+  `ReactHeadersTarget/include/React` and rewrites `framework module React` to a
+  plain `module React`, vended as the `ReactHeaders` target (see
+  `spm-header-paths-contract.md` in the SwiftPM docs).
+- `ReactNativeHeaders.xcframework` — headers-only; carries every other
+  namespace. Consumed by SwiftPM as a `binaryTarget` and by CocoaPods via the
+  `React-Core-prebuilt` pod (headers flattened onto the header search path).
+
+### CocoaPods consumption
+
+The `React-Core-prebuilt` pod vends `React.xcframework` (so `<React/...>` and
+`@import React;` resolve through the framework module via
+`FRAMEWORK_SEARCH_PATHS`) and flattens `ReactNativeHeaders.xcframework`'s
+headers into a top-level `Headers/` exposed on the pod header search path (so
+`<react/...>`, `<yoga/...>`, `<folly/...>` resolve). `rncore.rb` adds the
+`HEADER_SEARCH_PATHS` entry to `React-Core-prebuilt/Headers` for podspec,
+aggregate (main app), and third-party pod targets. No `-ivfsoverlay` flags are
+added.

+# How the prebuilt header layout is created — rules and rationale
+
+This documents the header-generation system introduced by the VFS-overlay
+removal PR (#57285): how every header that ships in the prebuilt artifacts is
+discovered, classified, placed, and made modular. The system lives in three
+scripts under `scripts/ios-prebuild/`:
+
+| Script                 | Role                                                                                                                                                          |
+| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `headers-inventory.js` | **Discover + classify** every shipped header (the facts)                                                                                                      |
+| `headers-spec.js`      | **The rules** (R1–R11) — turns the inventory into a layout plan + module maps                                                                                 |
+| `headers-compose.js`   | **Emit** — projects the plan into `React.xcframework` and `ReactNativeHeaders.xcframework`                                                                    |
+| `headers-verify.js`    | **Gate** — generator-time verification: include-health ratchet, structural byte-compare, consumer-shaped compile smokes (runs in the prebuild CI compose job) |
+
+One principle drives the whole design: **content authority = the source files,
+layout authority = the spec.** No header is ever edited; only _where it goes_
+and _which module owns it_ is computed.
+
+## Why this exists (what replaced the VFS overlay)
+
+Previously a clang VFS overlay synthesized a virtual header tree at build time
+so includes like `<React/RCTBridge.h>`, `<react/renderer/...>`, `<folly/...>`
+would resolve against the prebuilt artifact. That approach broke down under
+clang **explicit modules** (the overlay shadowed the framework's own module),
+made code-signature stability awkward, and required consumer-side machinery.
+
+The replacement is purely physical: two artifacts whose on-disk layout makes
+every include form resolve through standard mechanisms —
+`FRAMEWORK_SEARCH_PATHS` for `<React/...>` and a plain header search path for
+everything else. No overlay, no include rewriting, no consumer flags.
+

+```
+
+## Stage 1 — Inventory: discover and classify (headers-inventory.js)
+
+### Discovery
+
+Headers are enumerated through the **same podspec-driven discovery the prebuild
+itself uses** (`headers.js`), so the inventory cannot drift from the shipped
+set. Each header gets:
+
+- a **natural path** — the include path consumers actually write
+  (`React/RCTBridge.h`, `react/renderer/core/ShadowNode.h`, `yoga/Yoga.h`). This
+  is the canonical identity; the podspec `header_dir` supplies the namespace,
+  and header_dir-less pods get their pod name as prefix.
+- one or more **identities** — the physical source file plus the pod-namespaced
+  path. `React_RCTAppDelegate` headers get a **second, synthetic bare-root
+  identity** (`RCTAppDelegate.h` with no prefix) because app templates
+  historically wrote `#import <RCTAppDelegate.h>`.
+
+### Language classification
+
+`scanHeader()` does a guard-aware scan of each header's text:
+
+- Tracks a `#if/#ifdef __cplusplus` **stack**, so C++ constructs and includes
+  that only exist under a C++ guard don't taint the ObjC surface
+  (`cxxGuarded: true` edges).
+- ObjC markers: `@interface/@protocol/@implementation/@class/@end`,
+  `NS_ASSUME_NONNULL_BEGIN`.
+- C++ markers: `namespace`, `template <`, `extern "C++"`, `enum class`,
+  `constexpr`, `using namespace/alias` — plus one non-obvious heuristic: a **C++
+  default member initializer inside a struct/class aggregate**
+  (`struct X { CGFloat size = NAN; };`), which is illegal in C/ObjC but has no
+  keyword the line scan would catch.
+
+Result: `lang ∈ {objc, objcxx, cxx, c}`.
+
+### Include classification
+
+Every `#include/#import` is resolved and classified: `internal` (another shipped
+header — quoted includes are resolved against the source dir and mapped back to
+a natural path), `thirdParty` (folly/glog/boost/fmt/
+double-conversion/fast_float), `hermes`, `system` (Apple SDK), `std`,
+`metaInternal` (FB-internal, never resolvable in OSS), `otherPlatform`
+(android/jni), `notShipped` (our namespace but not in the shipped set — a
+flattening mismatch), `unresolved`.
+
+### The bucket — "can this header live in a clang module?"
+
+The key output. A **fixpoint over unguarded include edges** propagates two facts
+through the internal include graph: _does this header transitively reach C++?_
+and _which third-party libs does it reach?_ — considering only edges an ObjC
+consumer would actually follow (cxx-guarded edges are skipped).
+
+| Bucket                   | Meaning                                                                                                                                        |
+| ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
+| `objc-modular-candidate` | Pure ObjC surface; reaches no C++ and no third-party lib unguarded → **can** be a module member                                                |
+| `objc-blocked`           | ObjC header, but transitively reaches C++/third-party (e.g. Fabric headers importing `<react/renderer/...>`) → cannot be a clean module member |
+| `objcxx`                 | Mixed ObjC++ in the header itself                                                                                                              |
+| `cxx`                    | Pure C++ (also anything `.hpp`)                                                                                                                |
+
+Only `objc-modular-candidate` headers can enter module maps; everything else
+stays **textual** (resolved by search path at the consumer's use site — exactly
+the semantics the old VFS overlay provided).
+
+## Stage 2 — The rules (headers-spec.js)
+
+The spec's docblock is the contract; each rule exists because of a concrete
+failure mode:
+
+**R1 — `React.framework/Headers` root = the `React/` namespace, hoisted.** The
+framework _name_ supplies the `React/` prefix, so `#import <React/RCTBridge.h>`
+resolves verbatim through `FRAMEWORK_SEARCH_PATHS`. Bare root aliases (R6) also
+live here. The lowercase `react/` namespace is deliberately **not** here:
+resolving `<react/...>` through `React.framework` requires case-folding
+`react.framework` → `React.framework`, which only works on case-insensitive
+filesystems. The header-search-path route (R2) is exact everywhere.
+
+**R2 — every other namespace ships in ONE headers-only xcframework,
+`ReactNativeHeaders`.** Namespace dirs at its `Headers/` root: `react/`,
+`yoga/`, `jsi/`, `cxxreact/`, `React_RCTAppDelegate/`, … **including the
+third-party deps namespaces** (folly/glog/boost/fmt/double-conversion/
+fast_float, copied out of the ReactNativeDependencies artifact — which thereby
+becomes binary-only). SPM/Xcode auto-serve a binaryTarget's `Headers/` on the
+consumer's search path, so everything resolves with zero flags.
+
+**R3 — NO include rewriting, anywhere.** Shipped headers are byte-identical to
+the repo. If a header's includes don't work in the packaged layout, the fix is
+in the _source header_ or the _rules_ — never a packaging-time patch. This is
+what keeps source builds and prebuilt builds semantically identical.
+
+**R4 — the React framework module map is an umbrella over the _safe_ ObjC
+surface.** A header enters the umbrella iff `isUmbrellaSafe`:
+
+```text
+bucket == objc-modular-candidate
+∧ React/-namespace
+∧ no '+' in the filename            (category headers, e.g. +Private — see R9)
+∧ no C extern-inline definition
+```
+
+The extern-inline exclusion is empirical: a C99 `extern inline` definition emits
+a **strong symbol in every importing translation unit** → duplicate symbols at
+link (found via `RCTTextInputNativeCommands.h`). In practice this yields ~225
+umbrella headers out of ~317 in the framework.
+
+**R5 — every ReactNativeHeaders namespace with modular candidates gets a plain
+(non-framework) module** declaring exactly those candidates. Why: a framework
+module (React) may not _textually_ include non-modular headers under
+`-Wnon-modular-include-in-framework-module` — so when a React.framework header
+imports `<yoga/Yoga.h>`, yoga's header must itself belong to a module (found
+empirically via yoga + RCTDeprecation). Details:
+
+- Module _names_ are internal to clang's module graph — consumers never
+  `@import yoga`; they `#import <yoga/Yoga.h>` and clang maps the header to its
+  owning module.
+- The `react` namespace's module is renamed `ReactNativeHeaders_react` so it can
+  never alias the `React` framework module on a case-insensitive filesystem.
+  (Header paths are unchanged; only the module name differs.)
+- Namespaces whose name isn't a valid module identifier (`jsinspector-modern`,
+  `double-conversion`) are exempt — they currently have no modular candidates;
+  the verifier asserts that stays true.
+
+**R6 — bare includes migrate to `<React/X>`.** Bare root aliases
+(`RCTAppDelegate.h` etc.) are physically placed at the framework Headers root,
+so `<React/RCTAppDelegate.h>` works; the bare angle form
+(`#import <RCTAppDelegate.h>`) has no framework spelling and is the one
+accepted, measured ecosystem migration (~4 lines total).
+
+**R7 — sign AFTER composing.** The code signature pins the header manifest;
+composing after signing would invalidate it.
+
+**R8 — collisions are hard errors.** Two different source files may never
+project to the same destination path. `computeSpecPlan` throws; the artifact is
+not produced.
+
+**R9 — private React headers, exposed in the default `React` module via a
+curated allowlist.** Privileged framework consumers (Expo) import headers the
+public umbrella excludes. Rather than a `React.Private` submodule (which would
+force a Swift `import React.Private` in consumers) they are appended to the
+module map, split by bucket:
+
+```text
+framework module React {
+  umbrella header "React-umbrella.h"
+  header "RCTBridge+Private.h"                 // objc-modular-candidate → real member
+  textual header "RCTComponentViewFactory.h"   // objc-blocked → textual only
+  textual header "RCTMountingManager.h"        // (…6 Fabric headers total)
+  ...
+  export *
+  module * { export * }
+}
+```
+
+An `objc-blocked` header **must** be `textual` — a real member would re-trip the
+non-modular-include error that got it excluded from the umbrella in the first
+place. Textual works because its C++ includes resolve at the consumer's use
+site. "Private" is by convention (naming), not enforcement: a single binary
+artifact cannot hard-gate an app from headers a framework legitimately needs.
+Validation **fails closed**: an allowlisted header missing from the inventory,
+or a `modular` entry whose bucket drifted, aborts the build with a targeted
+message.
+
+**R10 — per-namespace umbrella headers, derived, for namespaces consumers
+probe.** Expo's `RCTAppDelegateUmbrella.h` does
+`__has_include(<React_RCTAppDelegate/React_RCTAppDelegate-umbrella.h>)` — a
+CocoaPods-era artifact filename. The flattened layout ships the individual
+headers but no umbrella, so the probe silently failed. The fix emits
+`<ns>/<ns>-umbrella.h` for each namespace in `UMBRELLA_NAMESPACES` (currently
+just `React_RCTAppDelegate`), with content **derived from the namespace's
+modular header set** — never hand-listed, so it can't drift (it correctly omits
+e.g. the since-removed `RCTArchConfiguratorProtocol.h`). The umbrella is also
+added to that namespace's R5 module so importing it stays modular. Fails closed
+if the namespace loses all modular headers.
+
+**R11 — one source file, one content location (redirect shims).** Some sources
+ship under several spellings: `React/X.h` plus a legacy pod-namespace form
+(`CoreModules/X.h`, `RCTAnimation/X.h`, `RCTImage/X.h`, …), or a bare root alias
+plus `React_RCTAppDelegate/X.h` — 116 sources at the time of writing. Under the
+VFS overlay every spelling mapped to _one physical file_, so `#import`-once and
+module ownership were coherent. A flattened layout that _copies_ the content
+breaks both: any `-fmodules` consumer touching two spellings — even
+transitively, e.g. importing legacy `<RCTImage/X.h>` whose header pulls a
+modular `<React/...>` — hits **redefinition errors** (found by the headers gate
+on its first run). The rule: the **module-owned spelling keeps the content**
+(the `React/` form when it exists — umbrella/module-React owner or canonical
+textual home; else the R5-module namespaced form), and every other spelling is
+emitted as a one-line redirect shim (`#import <owner>`). Shims that are
+namespace-module members are fine: they import the owning module, so
+declarations stay single-owned.
+
+## Stage 3 — Emission (headers-compose.js)
+
+`computeSpecPlan(rnRoot)` = inventory → plan, throwing on R8 collisions. Then:
+
+### `emitReactFrameworkHeaders` (per slice of React.xcframework)
+
+1. Stage all R1 entries (byte-copies of the source files) + the generated
+   `React-umbrella.h`.
+2. For each slice (`ios-arm64`, `ios-arm64_x86_64-simulator`, …): replace
+   `React.framework/Headers` with the stage, replace `Modules/` with the
+   generated module map (R4 + R9).
+3. (Stacked PR #57305 adds resource embedding here — `PrivacyInfo.xcprivacy` and
+   `RCTI18nStrings.bundle` per slice — orthogonal to headers.)
+
+### `buildReactNativeHeadersXcframework`
+
+1. Stage all R2 entries, then copy the six deps namespaces from
+   `third-party/ReactNativeDependencies.xcframework/Headers`. A declared deps
+   namespace that is missing is a **hard error** — previously a warn-and-ship,
+   which once produced a silently deps-less artifact (1.6 MB instead of 11 MB).
+2. Optionally fold in the `hermes/` public headers (consumer-side compose path).
+3. Write the R10 umbrella files, then the R5 module map.
+4. Compile a stub static archive per slice (headers-only artifacts still need a
+   library for `xcodebuild -create-xcframework`) and compose the xcframework.
+
+### `ensureHeadersLayout` (consumer-side)
+
+Applies the same emission to an already-downloaded cache slot (so any consumer
+with a cached `React.xcframework` gets composed artifacts without a published
+`ReactNativeHeaders`). Idempotent via a freshness marker (source realpath +
+mtime + hermes presence).

+- **CocoaPods**: `React-Core-prebuilt`'s `prepare_command` flattens

+  (`rncore_facades.rb`) so no source headers shadow the artifact.

+`DEPS_NAMESPACES` (headers-spec.js) is the single source of truth for
+third-party namespaces — the inventory's include classifier derives from it, and
+compose enforces set-equality with the deps artifact in both directions.
+
+The unit tests (`__tests__/headers-spec-test.js`) exercise R9/R10/R11, the R5
+exemption assert, the ratchet diff, and the gate fixtures red/green.
+
+## Resilience against new headers (drift analysis)
+
+The system is **derived-by-construction for the common case** — a new ordinary
+header requires zero maintenance — but its consumer-facing contracts are
+**allowlist-maintained** and only fail downstream. Grouped by _when_ a change
+surfaces (daily CI = prebuild compose + rn-tester prebuilt consumer lanes):
+
+### A. Auto-adapts — nothing to do
+
+- **New header in an existing pod**: podspec-glob discovery → inventory → placed
+  by R1/R2; joins the umbrella (R4) or its namespace module (R5) automatically
+  iff `isUmbrellaSafe`.
+- **New pod/namespace** (valid module identifier): gets an R5 module
+  automatically.
+- **New header in `React_RCTAppDelegate`**: joins the derived R10 umbrella.
+- **New `+Category` / extern-inline / objc-blocked header**: auto-excluded from
+  the modular surface — the _safe_ default for app consumers.
+
+### B. Fails loudly at compose time (the fail-closed guards)
+
+R8 collisions, R9 allowlist drift (rename/removal, modular→blocked), R10
+total-loss, missing deps namespaces, facade re-vend glob. These protect the
+spec's _own_ invariants and cannot silently regress.
+
+### C. Fails loudly at the GENERATOR — the headers gate (`headers-verify.js`)
+
+These classes previously failed late (consumer CI lane) or not at all; the gate
+— run in the prebuild compose job — moved them to compose time:
+
+- **A new umbrella member that doesn't compile standalone** (its include chain
+  hits a `notShipped` header, or the language scanner misbucketed a C++-only
+  header as C): the gate's ObjC TU precompiles the `React` module — compiling
+  _every_ umbrella header — at generator time.
+- **A broken R5 namespace module**: the gate imports one header from every
+  namespace module, precompiling each (previously lazy — a module rn-tester
+  never imported was latent).
+- **A public header gaining a quoted `#import "Private.h"` of a non-shipped
+  header**: recorded by the inventory (`quotedNotShipped`) and caught by the
+  include-health ratchet against `headers-include-baseline.json` — no compile
+  coverage needed.
+- **The privileged-consumer (Expo) contract**: the gate compiles an Expo-shaped
+  ObjC++ TU (every R9 textual Fabric header) and a Swift TU (`import React` +
+  `RCTBridge.moduleRegistry`), plus `__has_include` asserts for the R9/R10
+  surfaces — a tested invariant instead of a downstream discovery.
+
+Proof the gate earns its keep — its FIRST run found two real shipping defects:
+the dual-identity redefinitions that became R11, and an undeclared
+`SocketRocket` namespace in the deps artifact (caught by the set-equality guard
+the moment it was added). SocketRocket now lives in `DEPS_NAMESPACES` alongside
+the other third-party deps namespaces, with a single physical home in the
+ReactNativeDependenciesHeaders sidecar: relocating a second textual copy into
+ReactNativeHeaders collided with the real pod's own headers under
+`use_frameworks` (the duplicate-`@interface` / poisoned-module-graph Expo
+regression, 2026-07-03), so the set-equality gate asserts the declared namespace
+set — `DEPS_NAMESPACES` — matches the deps artifact's namespaces exactly, in
+both directions.
+
+### D. Remaining silent gaps — allowlist maintenance (by design)
+
+The contracts describing what _external_ consumers need are still curated lists;
+a new consumer need shows up downstream first, then becomes a one-line allowlist
+addition (now protected by the gate once added):
+
+1. **New privileged-consumer headers**: a new `+Private.h` or Fabric-class
+   objc-blocked header an Expo-class consumer starts importing —
+   `PRIVATE_REACT_HEADERS` is manual by design.
+2. **New umbrella-probe namespaces**: a consumer probing `<ns/ns-umbrella.h>`
+   for a namespace not in `UMBRELLA_NAMESPACES`.
+3. **Partial R10 shrink**: a `React_RCTAppDelegate` header flipping
+   modular→blocked drops out of the derived umbrella (fail-closed triggers only
+   on _total_ loss). Mitigated: the Expo probe surface is compile-tested, so a
+   shrink that breaks the umbrella itself is caught.
+
+### Remaining recommendation (not yet implemented)
+
+- **Artifact snapshot metrics** (per-namespace header counts, size bounds) as a
+  coarse tripwire for large silent drops beyond what the structural gate
+  byte-compares.

+/**
+ * THE HEADERS SPEC — executable contract for the packaged header layout.
+ *
+ * One source of truth: the prebuild compose step (headers-compose.js) EMITS
+ * artifacts from it, and the SPM tooling derives what consumers need from it
+ * (nothing extra, by design).
+ *
+ * The rules:
+ *
+ * R1. React.framework/Headers ROOT serves the `React/` namespace (contents
+ *     hoisted to root) plus the bare root aliases. The framework name supplies
+ *     the `React/` prefix, so `<React/RCTBridge.h>` resolves verbatim through
+ *     FRAMEWORK_SEARCH_PATHS. The `react/` (lowercase) namespace is NOT here —
+ *     it ships in ReactNativeHeaders (R2). Resolving it through React.framework
+ *     would require case-folding `react.framework` → `React.framework`, which
+ *     only works on case-insensitive filesystems; the header-search-path route
+ *     is exact and works everywhere.
+ * R2. Every other RN namespace (incl. `react/`) ships in ONE headers-only
+ *     library xcframework ("ReactNativeHeaders"), namespace dirs at its
+ *     Headers root. PURE-RN: the third-party deps namespaces (DEPS_NAMESPACES)
+ *     are NOT here — they ship in the ReactNativeDependenciesHeaders sidecar
+ *     built by the deps prebuild from its own artifact headers, so every
+ *     namespace has exactly ONE physical home (the SocketRocket dual-copy
+ *     regression class is structurally impossible). Both are served by exact
+ *     header-search-path lookup, so resolution is filesystem-case-independent.
+ * R3. NO include rewriting anywhere — source headers are byte-identical to
+ *     the repo (content authority = source files; layout authority = this
+ *     spec). Consumers compile unchanged except bare-form angle includes
+ *     (R6).
+ * R4. React.framework gets a framework module map with an umbrella over the
+ *     ObjC modular surface: objc-modular-candidate ∧ React/-namespace ∧ no
+ *     '+'-category header ∧ no C extern-inline definition (C99 extern inline
+ *     emits a STRONG symbol per importing .m TU → duplicate symbols;
+ *     RCTTextInputNativeCommands.h found empirically).
+ * R5. Every namespace with objc-modular-candidates gets a module declaring
+ *     exactly those candidates (framework modules may not textually include
+ *     non-modular framework headers; yoga + RCTDeprecation found
+ *     empirically). Namespaces whose name is not a valid module identifier
+ *     (e.g. jsinspector-modern) are exempt — they have no candidates today;
+ *     planFromInventory FAILS CLOSED if that changes. `react/` is also exempt: its few
+ *     objc-modular-candidates stay textual (as they already were inside
+ *     React.framework) so no `react` module aliases the `React` framework
+ *     module.
+ * R6. Bare root aliases are servable only as `<React/X>` — bare angle forms
+ *     (`#import <RCTAppDelegate.h>`) have no framework spelling. This is the
+ *     accepted, measured consumer migration (~4 lines ecosystem-wide).
+ * R7. Artifacts are code-signed AFTER header composition (signature pins the
+ *     header manifest).
+ * R8. Collisions are ERRORS: two different source files may never project to
+ *     the same destination path.
+ * R9. Private React headers — a curated allowlist of `<React/...>` headers the
+ *     umbrella (R4) excludes (they are `+`-suffixed and/or objc-blocked) — are
+ *     added to the React framework module map so privileged consumers can reach
+ *     them. The allowlist fails closed on drift (validatePrivateReactHeaders).
+ * R10. Per-namespace umbrella headers are emitted into ReactNativeHeaders so
+ *     consumers that import a whole namespace (e.g. Expo) get one entry point;
+ *     each is derived from namespaceModules (R5) so it cannot drift.
+ * R11. ONE source file, ONE content location. Some sources ship under several
+ *     spellings (React/X.h + a legacy pod-namespace form like CoreModules/X.h,
+ *     or a bare root alias + React_RCTAppDelegate/X.h). Under the VFS overlay
+ *     all spellings mapped to one physical file, so #import-once and module
+ *     ownership were coherent. The flattened layout would duplicate the
+ *     declarations — any -fmodules consumer touching two spellings (even
+ *     transitively: a legacy-spelling import whose header pulls a modular
+ *     <React/...>) hits redefinition errors. Therefore: the MODULE-OWNED
+ *     spelling keeps the content (the React/ form when it exists — it is the
+ *     umbrella/module-React owner or the canonical textual home; else the
+ *     R5-module namespaced form), and every other spelling is emitted as a
+ *     one-line redirect shim (`#import <owner>`). Shims that are namespace-
+ *     module members are fine: they import the owning module, so declarations
+ *     stay single-owned.

+ * Headers gate — verifies the composed prebuilt header layout at GENERATOR
+ * time, so consumer-facing regressions fail the prebuild instead of a
+ * downstream (rn-tester / Expo / community) build. Three stages:
+ *
+ *  1. INCLUDE HEALTH (no artifact needed): every shipped header's
+ *     notShipped / unresolved / quotedNotShipped includes are ratcheted
+ *     against a committed baseline (headers-include-baseline.json). A NEW
+ *     offender fails; a resolved one is reported so the baseline can shrink.
+ *     Update intentionally with --update-baseline.
+ *  2. STRUCTURAL: the composed artifact's module maps / umbrellas are
+ *     byte-identical to what the current spec renders, and the R9 private
+ *     headers + deps namespaces are physically present.
+ *  3. COMPILE (simulator SDK, syntax-only):
+ *     a. An ObjC TU that __has_include-asserts the R9/R10 surfaces, then
+ *        imports <React/RCTBridge.h> under -fmodules (precompiling the React
+ *        module = compiling EVERY umbrella header + the R9 modular member),
+ *        one header from every R5 namespace module (precompiling each), and
+ *        the R10 per-namespace umbrella.
+ *     b. A privileged-consumer ObjC++ TU (the Expo shape): textually imports
+ *        every R9 textual Fabric header against ReactNativeHeaders.
+ *     c. A Swift TU: `import React` + `RCTBridge.moduleRegistry` — the Expo
+ *        Swift case, proving the R9 modular header is module-visible.
+ *     d. Swift C++-interop TUs that import React plus every importable module
+ *        declared by the composed ReactNativeHeaders module map, then the
+ *        shipped inspector umbrella as an isolated probe module, forcing
+ *        ClangImporter to instantiate imported C++ value-type special members.

+ *   scaffold                   Generate Package.swift for community deps that
+ *                              lack SPM support.
+ *   sync / codegen / download  Advanced/internal: `sync` is invoked by the
+ *                              generated Xcode build phase; `codegen` and
+ *                              `download` run a single pipeline step.
+ *
+ * Zero-arg `npx react-native spm` auto-detects: a freshly-scaffolded CocoaPods
+ * project (clean tree, stock Podfile) → `add --deintegrate`; an injected
+ * project → `update`; otherwise → `add` (fails loud on a CocoaPods project,
+ * directing you to `--deintegrate`).
+ *
+ * Options:
+ *   --version <ver>             React Native version. Pinned into
+ *                               .spm-injected.json and reused by later runs
+ *                               until a new one is passed (default: the
+ *                               resolved node_modules/react-native version).
+ *   --yes                       Skip the dirty-pbxproj confirmation prompt.
+ *   [add] --xcodeproj <path>    Which .xcodeproj to inject into (when several).
+ *   [add] --product-name <name> Which app target to inject into (when several).
+ *   [add] --deintegrate         Run `pod deintegrate` + strip RN from the
+ *                               Podfile before injecting.
+ *   [advanced] --artifacts <path>          Local two-flavor artifact root;
+ *                               must contain debug/ and release/ cache slots.
+ *   [advanced] --download <auto|skip|force> Artifact policy (default: auto).
+ *   [advanced] --skip-codegen   Skip the react-native codegen step.
+ *   [advanced] --config-command <json> Override the autolinking config command.
+ *
+ * Steps performed (add/update):
+ *   1. react-native codegen → build/generated/ios/ + install SPM codegen template
+ *   2. generate-spm-autolinking-config.js → build/generated/autolinking/autolinking.json
+ *   3. generate-spm-autolinking.js → build/generated/autolinking/Package.swift
+ *   4. download-spm-artifacts.js → cache dir (per --download policy)
+ *   5. generate-spm-package.js → build/xcframeworks/Package.swift + symlinks
+ *   6. inject SPM packages into the existing .xcodeproj (in place)
+ *
+ * The injection is committed with your project; its XCLocalSwiftPackageReference
+ * entries point at stable sub-package paths under build/ (xcframeworks,
+ * generated/autolinking, generated/ios), so adding/removing community deps
+ * changes those sub-packages (gitignored) and never re-injects. No app-level

+# SwiftPM (Apple platforms) — Preview
+
+[🏠 Home](../../../../../__docs__/README.md)
+
+> **Preview.** SwiftPM support is an early preview: the commands, flags,
+> generated layout, and distribution model may change in future releases, and it
+> is not yet recommended for production. CocoaPods remains the supported
+> default.
+
+The scripts in `scripts/spm/` let a React Native iOS app consume React Native
+through **Swift Package Manager** instead of CocoaPods, using prebuilt
+XCFrameworks. Support is opt-in and additive: `npx react-native spm` injects
+package references into the app's existing `.xcodeproj` in place, and `deinit`
+reverses exactly what it injected.
+
+The motivation, staged migration plan, and open questions live in
+[RFC0994](https://github.com/react-native-community/discussions-and-proposals/blob/main/proposals/0994-swift-package-manager-support-for-react-native-ios-projects.md).
+The documents here describe how the implementation actually works.
+
+## 🚀 Usage
+
+```bash
+cd ios
+npx react-native spm      # add on first run, update thereafter
+```
+
+**If any autolinked dependency ships no `Package.swift`, this stops with
+`error: Package.swift is missing for library "<name>"` and exit code 2.** That
+is deliberate — `add` and `update` never scaffold silently, so a missing
+manifest is visible and fixed on purpose. Generate the manifests first, then
+re-run setup:
+
+```bash
+npx react-native spm scaffold   # writes Package.swift into node_modules/<dep>/
+npx react-native spm            # then inject as usual
+```
+
+Because `node_modules` isn't committed, persist each scaffolded manifest with
+`npx patch-package <dep>` and commit the patch — otherwise the same error
+returns on every fresh install and in CI. Better still, contribute the manifest
+upstream. See
+[Community packages without a Package.swift](./spm-scripts.md#community-packages-without-a-packageswift).
+
+See **[spm-scripts.md](./spm-scripts.md)** for the CLI actions and flags,
+CocoaPods migration, brownfield apps, what to commit, fresh clones and CI, and
+troubleshooting.
+
+## 📐 Design
+
+Three documents cover the design, each owning one area:
+
+| Document                                                       | Covers                                                                                                                                                                                                                          |
+| -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| [spm-scripts.md](./spm-scripts.md)                             | The tool itself: CLI surface, the six-step pipeline, [every file it creates or modifies](./spm-scripts.md#files-the-tool-touches), the two auto-sync hooks, and how Debug/Release flavor selection works.                       |
+| [spm-header-paths-contract.md](./spm-header-paths-contract.md) | How headers and package references resolve. The contract is **zero-`-I`**: no header search paths and no `unsafeFlags` in any generated manifest. Also covers remote mode.                                                      |
+| [spm-autolinking-plugins.md](./spm-autolinking-plugins.md)     | The extension seam for frameworks with their own module system (Expo is the first consumer): discovery, the full context/return contract including `flavoredFrameworks`, `watchPaths` and `scriptPhases`, and failure behavior. |
+
+Two ideas explain most of the architecture:
+
+- **Headers go through SwiftPM; runtime binaries do not.** A `binaryTarget`
+  cannot vary by build configuration, but React Native ships flavored binaries
+  (a debug `React.framework` carries the dev menu and assertions; release strips
+  them). So the package graph vends headers only, and the flavored frameworks
+  are linked and embedded through generated Xcode build settings instead.
+- **Generated state is regenerable, and the injection is reversible.**
+  Everything under `build/` is gitignored and rebuilt from the app's
+  `package.json`; everything written into the `.xcodeproj` is recorded in a
+  `.spm-injected.json` marker so `deinit` can undo precisely that.
+
+## 🔗 Relationship with other systems
+
+### Part of
+
+- iOS build system — the alternative to the CocoaPods integration in
+  [`scripts/cocoapods/`](../../cocoapods).
+
+### Used by this
+
+- **Prebuilt XCFrameworks** from [`scripts/ios-prebuild/`](../../ios-prebuild) —
+  produces the `React`, `ReactNativeDependencies`, `hermes-engine`, and
+  headers-only artifacts that these scripts download, stage, and link.
+- **Codegen** (`generate-codegen-artifacts.js`) — its output is installed as a
+  local `React-GeneratedCode` package rather than a Pod.
+- **`@react-native-community/cli config`** — supplies the autolinking metadata
+  (`autolinking.json`) that the SwiftPM autolinker turns into a `Package.swift`.
+  Overridable via `--configCommand`.
+
+### Uses this
+
+- Apps opting into SwiftPM, via the `spm` React Native CLI command.
+- Frameworks layering their own module system on top of React Native, via
+  [autolinking plugins](./spm-autolinking-plugins.md).

+# SwiftPM Autolinking Plugins (Preview)
+
+> **Preview / unstable contract.** The discovery mechanism and the plugin
+> function's context/return shape may change while the first consumers (Expo)
+> validate it. Pin to a React Native version if you depend on it.
+
+How a framework with its own module system — Expo is the first consumer —
+contributes to the SwiftPM autolinking graph that `npx react-native spm`
+generates. See [spm-scripts.md](./spm-scripts.md) for the base tool.
+
+## Why a plugin (not a static list or a post-process)
+
+The documented extension points don't cover a framework:
+
+- `spm.modules` in `react-native.config.js` is a **static** list of simple
+  source modules. A framework discovers its modules **dynamically** (scanning
+  `node_modules`), generates a **module registry**, and ships mixed
+  Swift/ObjC/C++ modules (e.g. `ExpoModulesCore`) that `spm scaffold` can't
+  handle.
+- A one-shot **post-process** of the generated `Package.swift` is **clobbered on
+  the next sync**: the Xcode [auto-sync hooks](./spm-scripts.md#auto-sync)
+  re-run autolinking on every dependency change. A framework's contribution must
+  run _whenever autolinking runs_.
+
+A plugin is exactly that. It is invoked from `generate-spm-autolinking.js`'s
+`main()` — the single function that both `add` / `update` **and** the build-time
+`sync` call — so the contribution is regenerated on every build and never goes
+stale.
+
+(This is the SwiftPM analog of the seams CocoaPods gave Expo: the Podfile,
+`use_expo_modules!`, and `react_native_post_install` hooks.)
+
+## Discovery — transitive, zero app config
+
+A dependency opts in from its **own** `react-native.config.js`, so installing
+the framework is enough (mirrors how CocoaPods pulls in `use_expo_modules!`
+transitively):
+
+```js
+// node_modules/expo/react-native.config.js
+module.exports = {
+  spm: {autolinkingPlugin: './spm/autolinking-plugin.js'},
+};
+```
+
+The autolinker already walks every dependency's `react-native.config.js`; any
+that declares `spm.autolinkingPlugin` is `require`d and invoked. No app-level
+registration or allowlist is required.
+
+**Opt-out escape hatch.** An app can exclude a plugin from its own
+`react-native.config.js`:
+
+```js
+module.exports = {
+  spm: {denyPlugins: ['some-framework']}, // npm names to skip
+};
+```
+
+## The contract
+
+A plugin is a function exported from the module named above
+(`module.exports = fn`, or `default` / `plugin` named exports also work):
+
+```js
+module.exports = function plugin(context) {
+  return {
+    packageDependencies: [
+      // Local package (e.g. a scanned module dir) …
+      {
+        name: 'ExpoModulesCore',
+        path: '../../../node_modules/expo-modules-core/ios',
+      },
+      // … or a remote/published package:
+      // {name: 'SomePkg', url: 'https://…/SomePkg.git', version: '1.2.3'},
+    ],
+    productDependencies: [
+      // Linked by the app's AutolinkedAggregate target:
+      {name: 'ExpoModulesCore', package: 'ExpoModulesCore'},
+    ],
+    generatedSources: [
+      // e.g. the generated module registry, registered with codegen:
+      {path: 'build/generated/expo/ExpoModulesProvider.swift'},
+    ],
+    flavoredFrameworks: [
+      // Precompiled dynamic XCFrameworks that come in mandatory Debug/Release
+      // pairs. RN validates and stages both outside the SwiftPM graph.
+      {
+        id: 'expo-modules-core',
+        frameworkName: 'ExpoModulesCore',
+        linkage: 'dynamic',
+        flavors: {
+          debug: '/…/output/debug/xcframeworks/ExpoModulesCore.xcframework',
+          release: '/…/output/release/xcframeworks/ExpoModulesCore.xcframework',
+        },
+      },
+    ],
+    watchPaths: [
+      // Inputs whose edits must re-trigger the auto-sync — the plugin's own
+      // manifest and per-module config (absolute paths, dirs or files):
+      '/…/node_modules/expo/Package.swift',
+      '/…/node_modules/expo/expo-module.config.json',
+    ],
+    scriptPhases: [
+      // Build-time shell phases on the app target — SwiftPM's missing
+      // `script_phase`:
+      {
+        id: 'expo-constants.generate-app-config',
+        name: 'Generate Expo App Config',
+        script: '"$NODE_BINARY" .../createExpoConfig.js',
+        position: 'beforeCompile', // default: 'end'
+        inputPaths: ['$(SRCROOT)/../app.config.js'],
+        outputPaths: ['$(DERIVED_FILE_DIR)/EXConstants.bundle/app.config'],
+        alwaysOutOfDate: true,
+      },
+    ],
+  };
+};
+```
+
+### `flavoredFrameworks` — per-configuration precompiled frameworks
+
+Each entry is
+`{id, frameworkName, linkage: 'dynamic', flavors: {debug, release}}`. Both
+flavor paths must be absolute and present when `spm add` or `spm update` runs.
+The framework and executable names, public headers, and platform slices must
+agree across flavors. Static binaries, nested frameworks, duplicate IDs, and
+duplicate embedded framework names are fatal.
+
+The declarations are recorded to
+`<outputDir>/.spm-plugin-flavored-frameworks.json`, normalized into the same
+immutable app-local slots as React Native, and added to Xcode's exact linker and
+embed settings. They are not emitted as SwiftPM product dependencies. Adding or
+removing one requires `spm update`; the build-time `spm sync` intentionally does
+not mutate runtime framework settings.
+
+### `watchPaths` — plugin staleness inputs
+
+`watchPaths` is an array of **absolute** paths (dirs **or** files) the Xcode
+auto-sync hooks watch to decide whether they must re-sync. RN already watches
+each module's source dir plus every npm dep's checked-in `Package.swift` and
+`.react-native/` dir; a plugin adds the inputs only it knows about — e.g.
+`packages/expo/Package.swift`, `expo-module.config.json`, and per-module
+manifests. On the next build the phase re-syncs when a watched **file** is newer
+than the last sync, a watched **dir** has a newer child, or a watched path has
+**vanished** (a rename forces a re-sync so the config error surfaces).
+
+Unlike `flavoredFrameworks`, watch paths are best-effort: a non-array is ignored
+with a warning (never fatal), and each non-string / empty / **relative** entry
+is dropped with a warning. Absolute-only, because the generated phase tests
+these paths with no cwd context. The kept paths are folded into
+`<outputDir>/.spm-sync-watch-paths` alongside RN's own, then deduped and sorted.
+
+### `scriptPhases` — build-time shell phases on the app target
+
+SwiftPM has no equivalent of CocoaPods' `script_phase`, so a framework that must
+run a script during the app's build — `expo-constants` writing
+`EXConstants.bundle/app.config` is the first consumer — declares it here. Each
+entry is recorded to `<outputDir>/.spm-plugin-script-phases.json`, which
+`spm add` / `spm update` reads to emit one `PBXShellScriptBuildPhase` per entry
+on the injected app target:
+
+| Key                          | Meaning                                                                                                                                                                                                                                                                                                                         |

Renaming it is a _remove + add_, not a rename. |

+| `position`                   | `'beforeCompile'` or `'end'`. Optional, default `'end'` — see **Placement** below.                                                                                                                                                                                                                                              |
+| `inputPaths` / `outputPaths` | Optional Xcode input/output file lists, which is what lets Xcode skip an up-to-date phase.                                                                                                                                                                                                                                      |
+| `alwaysOutOfDate`            | Optional; when `true` the phase runs on every build regardless of its file lists.                                                                                                                                                                                                                                               |
+
+**Placement.** `'end'` appends at the true end of the target's `buildPhases` —
+after the app's own JS-bundle phase. `'beforeCompile'` lands directly after the
+"Sync SPM Autolinking" phase, which stays first because it regenerates the
+content everything else reads, and always **before Sources**: React Native never
+re-seats its own sync phase, so if you have dragged that below Sources your
+`beforeCompile` phases are seated ahead of Sources instead of following it.
+Phases sharing a position keep their declared order.
+
+**Position is enforced on every sync.** `add`/`update` compares where the plugin
+phases actually sit in `buildPhases` against the declared placement and, **only
+when the two differ**, lifts their membership lines and re-seats them in
+declared order. So changing `position` — or swapping two phases that share one —
+takes effect on the next `spm add`/`update`, with no remove + re-add. When they
+agree nothing is rewritten, which is what keeps an unchanged declaration
+re-syncing to a byte-identical project. The consequence worth knowing: a phase
+you **drag somewhere else in Xcode is moved back** to its declared position on
+the next sync, because the plugin's declaration is the source of truth. Only the
+`id` behaves differently — it is a key, not a label, so renaming it is a remove
+
+- add.
+
+Phases are injected by `spm add` / `spm update` **only**. The build-time `sync`
+rewrites the sidecar but never touches the `.xcodeproj`, so a newly declared
+phase appears on the next `add`/`update`, not on the next build. Each phase's
+UUID is derived from its `id` and recorded in the `.spm-injected.json` marker's
+`scriptPhases` map, so a re-run refreshes the phase's `name`, `script`, path
+lists, `alwaysOutOfDate` and placement in place, `update` removes phases that
+left the sidecar, and `deinit` reverts all of them.
+
+Validation is **fatal**, like `flavoredFrameworks` and unlike `watchPaths`: a
+non-array `scriptPhases`, a malformed entry, or a duplicate `id` (within one
+plugin or across plugins) aborts the run. A silently dropped phase would produce
+a green build whose generated content was never written — a runtime failure with
+no build-time signal — and two phases sharing an `id` would collapse onto one
+ledger key. `__proto__`, `constructor`, and `prototype` are rejected as ids even
+though the charset admits them: as keys of that ledger they never become own
+properties, so the phase would look recorded, disappear when the marker is
+serialized, and be unremovable by `deinit`.
+
+**Hostile names.** A `name` reaches the project file twice. In the `name` field
+— what Xcode displays — it lands verbatim, escaped as an OpenStep string, so any
+single-line string is expressible. Beside the phase's UUID, on the object's
+definition line and on its `buildPhases` member line, it also becomes a
+`/* … */` comment; those comments are cosmetic (Xcode regenerates them from the
+`name` field) but the text around them is scanned by delimiter, so the name is
+**normalized** there: `{}(),;="*/`, tabs and whitespace runs collapse to single
+spaces (`spm-pbxproj.js`'s `commentSafe`), falling back to the phase `id` —
+normalized the same way — and then to no comment at all if nothing survives
+either. Without that, a `{` in a comment would make the injector read the next
+object's body as this one's, and a `,` would make `deinit` delete the wrong line
+— corruption with no error. Only a line break is therefore rejected outright; a
+name is a display name, and no Xcode phase name spans lines.
+
+The injector's read of the sidecar is deliberately lenient — the file does not
+exist yet on a first `spm add`, and a stale or hand-edited copy must not break
+injection. An absent file yields no phases silently, an unparseable one warns,
+and a single entry failing the same checks (bad or reserved `id`, empty or
+multi-line `name`, missing `script`, unknown `position`, duplicate `id`) is
+**skipped, never coerced** — the sidecar is the only gate on a hand edit, so it
+enforces exactly the rules the plugin contract does.
+
+**Gating is the script's job.** The phase runs for every configuration and
+platform the target builds; if it should be a no-op for some of them (Release
+only, simulator only, …), the script must check `$CONFIGURATION` /
+`$PLATFORM_NAME` and exit early.

+| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `appRoot`         | The Xcode project directory (`<app>/ios`) being injected — **not** the app package root. Deriving package-root-relative paths from it (e.g. `path.join(appRoot, 'node_modules')`) silently breaks; use `projectRoot` for that. |
+| `projectRoot`     | The JS root (nearest `package.json`) — where the framework scans `node_modules`.                                                                                                                                               |

+| `autolinking`     | Parsed `autolinking.json` — RN's already-discovered deps, so the plugin can react to them.                                                                                                                                     |

+
+#### `context.react` — depending on React
+
+A plugin that emits its own `Package.swift` must declare React as a dependency.
+Rather than re-deriving React Native's package path, identity, and product names
+— which differ between local and remote mode and **move as RN repackages** —
+take them from `context.react`:
+
+```js
+react: {
+  packageRef:
+    {name: 'ReactNative', path: '<absolute>', relPath: '<relative-to-outputDir>'} // local
+    | {name: '<identity>', url: '<url>', version: '<version>'},                   // remote (SPM-resolved)
+  products: [
+    {name: 'ReactHeaders', package: 'ReactNative'},
+    {name: 'ReactNativeHeaders', package: 'ReactNative'},
+    {name: 'ReactNativeDependenciesHeaders', package: 'ReactNative'},
+    {name: 'ReactAppHeaders', package: 'React-GeneratedCode'}, // ← separate, per-app package
+  ],
+}
+```
+
+Local vs remote is signalled by which `packageRef` keys are present (`path` xor
+`url`+`version`). `packageRef.path` is **absolute** — always correct no matter
+which subdirectory of `outputDir` the plugin writes its own manifest into (the
+generated manifests are gitignored and regenerated every sync, so there's no
+portability cost); `relPath` (relative to `outputDir`) is provided as a
+convenience. `products` is the set React Native wires into **its own**
+autolinked targets (so a plugin's target compiles against exactly RN's React
+surface), filtered to those resolvable this run — every listed product is safe
+to reference without guarding. Note the fourth entry: `ReactAppHeaders` lives in
+the separate `React-GeneratedCode` package (per-app codegen), which a
+hand-rolled plugin would miss, and which is omitted when that package is absent.
+Because RN derives this list from one source of truth alongside its own product
+wiring, it stays correct across repackaging.
+

+| `scriptPhases`        | Recorded for `spm add` / `update` to emit one `PBXShellScriptBuildPhase` per entry on the app target. Malformed entries and duplicate `id`s are fatal. |
+
+The plugin returns **data** — it never writes into React Native's generated
+tree. RN owns the merge, so a re-sync reproduces the same `Package.swift`
+byte-for-byte (idempotent). Package and product contributions are **deduped by
+name** across plugins.

+
+Because steps 1–4 run in the one `main()`, everything above shares the same seam
+— there is no separate hook to wire for the build-time path.
+
+## Failure behavior
+
+Fail-closed and **named**: a plugin that fails to load, doesn't export a
+function, throws, or returns a malformed contribution aborts the run with a
+message identifying the framework. A framework silently dropping its modules (a
+green build missing native code) is worse than a loud stop.
+
+## Status & open items (Preview)
+
+- **Implemented & tested:** discovery (transitive + deny-list), invocation,
+  package + product merge, fail-closed validation, and dual-flavor framework
+  normalization/link/embed outside SwiftPM.
+- **Implemented & tested:** `generatedSources` **app-target wiring**. The merge
+  writes `.spm-plugin-generated-sources.json`; the `spm add`/`update` xcodeproj
+  injector (generate-spm-xcodeproj.js) reads it and wires each source **into the
+  app target** — a `PBXFileReference` + `PBXBuildFile` + a Sources-build-phase
+  entry, parented under one "SPM Generated Sources" navigator group. This is
+  what makes an `@objc` class (e.g. Expo's `ExpoModulesProvider`) reach the ObjC
+  classlist: a class inside the static Autolinked aggregate never does, so
+  `NSClassFromString` discovery would fail. Paths are stored SRCROOT-relative
+  when under the app root (the usual `build/generated/…` case), else absolute
+  (`sourceTree = "<absolute>"`). All UUIDs are namespaced on the normalized path
+  (deterministic/idempotent) and recorded in the `.spm-injected.json` marker's
+  `generatedSources` map, so `deinit` reverts them and `update` reconciles
+  entries that left the manifest. A target without a Sources phase logs loudly
+  and skips the wiring (injection otherwise succeeds). v1 targets only the
+  injected app target and assumes `.swift` in practice (`.m`/`.mm` are mapped as
+  future-proofing).
+- **Implemented & tested:** `scriptPhases`, contract through injection.
+  `invokePlugins` validates every entry fatally (`id` charset plus the reserved
+  `__proto__`/`constructor`/`prototype` names, a single-line `name`, a required
+  `script`, the `position` enum, optional path lists and `alwaysOutOfDate`, plus
+  duplicate `id`s), and the merge always rewrites
+  `.spm-plugin-script-phases.json` — `[]` when no plugin declares any, so
+  removing a plugin clears stale entries. The `spm add`/`update` xcodeproj
+  injector reads that sidecar and emits one `PBXShellScriptBuildPhase` per entry
+  on the app target at the requested position, recording the id→UUID map in the
+  `.spm-injected.json` marker so a re-run refreshes each phase's content in
+  place, re-seats it when its declared position or order changed, `update`
+  removes phases that left the sidecar, and `deinit` reverts them. Like
+  `flavoredFrameworks`, the build-time `sync` only rewrites the sidecar; it
+  never mutates the project.
+- **Co-design with Expo (not final):** codegen **provider ordering** — codegen
+  must consume the same discovered module set the plugin contributes — is
+  intentionally left for the first real plugin to drive to a stable shape.
+- Contract to be ratified via RFC once Expo's plugin proves it (framed as a
+  generic hook, not Expo-specific code in RN).

+# SPM headers & package references — how they resolve
+
+React Native's SPM consumption is **zero-I**: no `-I` / `-F` header search paths
+and no `unsafeFlags` in any generated manifest. Headers are served by SPM
+products/binary targets, and every generated `Package.swift` references the
+React Native + codegen packages with plain, fixed-relative paths computed at
+generation time (no runtime discovery). This document is the single source of
+truth for how that resolves.
+
+> History: earlier iterations materialized two header trees and fed them to
+> consumers as `-I` flags read from `spm-paths.json` /
+> `.react-native/paths.json` via an inlined Swift loader. That whole mechanism
+> (the loader `renderRNPathsLoader`, the `writeAppPathsJson` /
+> `writeSharedPathsJson` writers, and both JSON files) has been **deleted** —
+> manifests are now declarative. If you find a reference to those files, it is
+> stale.
+
+## How headers resolve (no search paths)

+
+The one remaining materialized header tree is the per-app farm at
+`<appRoot>/build/generated/ios/ReactAppHeaders` (built by
+`buildPerAppHeaderTree` in `spm-utils.js`, called from the orchestrators). It is
+vended as the `ReactAppHeaders` SPM target — consumers reach it through a
+product dependency, never through `-I`.
+
+`autolinking.json` (the `@react-native-community/cli config` output) is an INPUT
+used to generate the manifests; it is never read by a manifest.
+
+## How each manifest references the React + codegen packages
+
+Every generated manifest sits at a known depth inside the app and is regenerated
+on every `react-native spm` run, so package references are plain fixed-relative
+paths — no walk-up, no JSON, no `import Foundation`.
+
+| Manifest                 | Location                                       | How it references the React + codegen packages                                                                       |

+| Per-dep synth wrapper    | `build/generated/autolinking/packages/<Name>/` | `.package(path: "../../../../xcframeworks")` + `"../../../ios"`                                                      |
+| Codegen template         | `build/generated/ios/Package.swift`            | `.package(path: "../../xcframeworks")` (or the remote url)                                                           |
+| App target (pbxproj)     | `<App>.xcodeproj`                              | local `XCLocalSwiftPackageReference` (or `XCRemoteSwiftPackageReference` in remote mode)                             |
+| Scaffolded community lib | `node_modules/<dep>/Package.swift`             | scaffold-time relative paths to the app's xcframeworks + codegen packages (or `.package(url:exact:)` in remote mode) |
+
+## Remote-package mode
+
+Remote mode is gated by a **URL alone** — `RN_SPM_REMOTE_URL` (or the persisted
+`url`). When set, the whole app graph flips to a single remote React Native
+package identity: `.package(path: build/xcframeworks)` becomes
+`.package(url:exact:)` everywhere (aggregator/synth/codegen template/pbxproj),
+and the local artifact download + compose is skipped. SPM's
+one-version-per-package rule then unifies app + every library on one resolved
+React Native. The package identity is derived from the URL tail (swift-tools 6
+dropped `.package(name:url:)`) — nothing hardcodes a repo name.
+
+**Version is derived from npm, not pinned by hand.** The SPM-pinned RN version
+is not a free parameter: the SPM graph must compile against the same React
+Native the JS/native code uses, so the app (graph root) pins EXACT to the
+_installed_ RN version, read from `node_modules/react-native/package.json`.
+`RN_SPM_REMOTE_VERSION` and the persisted `versionOverride` are **overrides**,
+not the source of truth — they're only needed when the installed version isn't
+publishable (e.g. the monorepo `1000.0.0` dev placeholder, which has no remote
+tag). A _derived_ version is never persisted, so an `npm install` that upgrades
+RN auto-re-pins the SPM graph on the next `spm` run; an _override_ is persisted
+as `versionOverride` so it survives Xcode-phase re-syncs without the env.
+
+Persisted schema is `{url, versionOverride?}`. Legacy `{url, version}` is still
+read, with `version` honored as an override (back-compat). If remote mode is on
+but no usable version can be resolved — react-native isn't installed, or it's a
+non-publishable dev placeholder and no override is set — the tooling errors
+(exit 2, a hard Xcode build error) directing you to set `RN_SPM_REMOTE_VERSION`
+or install a released react-native, rather than silently pinning an unpublished
+tag.
+
+## Hand-authored community library contract
+
+A library that ships its own `Package.swift` (no scaffolder/autolinker marker)
+is left untouched by the tooling. It needs only two things, and **no discovery
+code**:
+
+1. Depend on the React Native SPM package and its products — in remote mode
+   `.package(url: "<repo>", exact: "<version>")` +
+   `.product(name: "ReactNative", …)` and
+   `.product(name: "ReactNativeHeaders", …)`. (Libraries should declare a
+   version RANGE in production; the consuming app pins EXACT.)
+2. Ship its own generated code: set `codegenConfig.includesGeneratedCode: true`
+   and generate with
+   `generate-codegen-artifacts.js --path . --targetPlatform ios --source library`.
+   Output lands at `<outputDir>/build/generated/ios/ReactCodegen/`, reachable
+   from the manifest with one safe `.headerSearchPath(...)` into the library's
+   own tree. The app-side codegen then skips the lib's spec (no duplicate
+   symbols).
+
+This makes the library self-contained — it carries no app-layout knowledge and
+needs no per-app codegen headers from the consuming app. Proven with
+`@chrfalch/react-native-calculator` (a hand-authored Fabric/TurboModule lib).

+# SwiftPM Scripts – React Native iOS via Swift Package Manager (Preview)
+
+> **Preview.** SwiftPM support is an early preview: the commands, flags,
+> generated layout, and distribution model may change in future releases, and it
+> is not yet recommended for production. Feedback is welcome. CocoaPods remains
+> the supported default.
+
+Build React Native iOS apps using **Swift Package Manager** with prebuilt
+XCFrameworks, as an alternative to CocoaPods. It is **opt-in and additive** —
+CocoaPods remains the default; `spm` injects into your existing `.xcodeproj` in
+place and is fully reversible.
+
+## Quick Start
+
+```bash
+cd ios
+
+# First-time setup: injects SwiftPM packages into your existing MyApp.xcodeproj,
+# in place. `npx react-native spm` with no action auto-resolves to `add` (or
+# `update` once injected); on a fresh CocoaPods app it converts in one command
+# (implies --deintegrate). To do it explicitly:
+npx react-native spm add --deintegrate
+
+# Open in Xcode (or `npm run ios`). Incremental dep changes auto-sync on build.
+open MyApp.xcodeproj
+```
+
+After the initial run, the project carries **auto-sync hooks** that detect
+dependency changes and re-run autolinking before compilation (see
+[Auto-Sync](#auto-sync)) — you don't re-invoke `react-native spm` manually for
+day-to-day dependency changes. **On a fresh clone or CI checkout, run
+`npx react-native spm` once before building** (see
+[Fresh clones & CI](#fresh-clones--ci)).
+
+> **Note:** `react-native spm` is a thin wrapper over
+> `node node_modules/react-native/scripts/setup-apple-spm.js`. If the CLI alias
+> is unavailable in your environment, invoke the script directly with the same
+> actions and the kebab-case flag equivalents (e.g. `--skip-codegen`).
+
+## CocoaPods → SwiftPM migration
+
+`spm add` injects into a project that is **not** CocoaPods-integrated. On a
+CocoaPods app it fails loud and points you at `--deintegrate`, which:

+1. runs `pod deintegrate` — removes CocoaPods integration from the `.xcodeproj`
+   (Pods references, `[CP]` build phases, xcconfig links). Your `Podfile` is
+   left on disk.
+2. strips **only** the React Native directives (`use_react_native!`,
+   `use_native_modules!`, `prepare_react_native_project!`) from the Podfile —
+   every other line, **including your own `pod '…'` entries, is preserved**.
+3. injects SwiftPM into the `.xcodeproj`.
+
+React Native now comes from SwiftPM; no pods are linked yet (deintegrate removed
+the integration).
+
+### Keeping non-RN pods
+
+Non-RN pods can stay side-by-side. After `spm add --deintegrate` your Podfile
+still lists them (only the RN directives were removed) — re-integrate them with
+a normal install:
+
+```bash
+pod install     # re-integrates the remaining (non-RN) pods; (re)creates the .xcworkspace
+```
+
+Then **open the `.xcworkspace`** (not the `.xcodeproj`): the workspace includes
+the SwiftPM-injected project, so React Native resolves through SwiftPM and your
+other pods through CocoaPods, together.
+
+> **Do not re-add `use_react_native!`.** React Native must be provided by
+> _either_ SwiftPM _or_ CocoaPods, never both — they share `build/generated/`,
+> so a dual-managed RN does not build. `spm add` refuses to run while the
+> Podfile still declares `use_react_native!`.
+
+The migration is fully reversible — see
+[Removing / resetting](#removing--resetting).
+
+## Brownfield apps
+
+`spm add` injects into your existing `.xcodeproj` in place, so an app that
+embeds React Native works the same way — point it at the right project and
+target:
+
+```bash
+npx react-native spm add --xcodeproj MyApp.xcodeproj --productName MyApp
+```
+
+**Requirement:** the `.xcodeproj` must live **inside the React Native JS tree**
+— i.e. the app's `package.json` is a parent directory of the project. Both setup
+and the build-time sync locate React Native by walking up from the project to
+the nearest `package.json`. The common "native project at the repo root with the
+RN JS in a sibling/child subfolder" layout is **not supported yet** — there is
+no way to point at a JS root outside the project's ancestors.
+
+Brownfield apps that keep CocoaPods for their other native dependencies follow
+the [coexistence rules above](#keeping-non-rn-pods): React Native from SwiftPM,
+everything else from CocoaPods, and no `use_react_native!` in the Podfile.
+
+## CLI Actions
+
+```bash
+react-native spm [action] [options]
+```
+
+With no action, the command **auto-resolves**: if SwiftPM has been injected
+(`.spm-injected.json` marker present) it routes to `update`; otherwise `add`. On
+a freshly-scaffolded CocoaPods project (clean git tree, stock Podfile) the
+zero-arg path additionally implies `--deintegrate` (the safe-gate), so
+`npx react-native spm` converts a brand-new app to SwiftPM in one command.
+
+When invoked from the JS root of a standard RN app (sibling `ios/` subdir), the
+command auto-redirects into `ios/` with a banner.

+| `--configCommand <json>`         | [advanced] JSON array of the argv used to generate `autolinking.json`, overriding the default `@react-native-community/cli config` command. Also settable via the `RCT_SPM_AUTOLINKING_CONFIG_COMMAND` env var. Either way the value is remembered, so you pass it once. Example: `'["npx","expo-modules-autolinking","react-native-config","--json","--platform","ios"]'` |
+
+### The autolinking config command is remembered
+
+An app that replaces `@react-native-community/cli` autolinking (an Expo app, for
+example) has to tell `spm` how to produce `autolinking.json`. Pass the command
+once, on `add` or `update`:
+
+```bash
+npx react-native spm add --configCommand '["npx","expo-modules-autolinking","react-native-config","--json","--platform","ios"]'
+```
+
+Every action that needs `autolinking.json` — `add`, `update`, `scaffold`, and
+the build-time `sync` — resolves the command in this order:
+
+1. `--configCommand`
+2. `RCT_SPM_AUTOLINKING_CONFIG_COMMAND`
+3. the `configCommand` pinned in `MyApp.xcodeproj/.spm-injected.json` by an
+   earlier `add`/`update`
+4. the default `@react-native-community/cli config`
+
+`add`/`update` pin whichever of the first two routes supplied the command,
+validated as an argv array; a later run that passes neither keeps the existing
+pin, and passing `--configCommand` again replaces it. The pin exists because the
+**Sync SPM Autolinking** build phase inherits neither your flag nor the shell
+that exported the env var — without it, a successful `add` is followed by
+failing builds, because the phase re-derives `autolinking.json` with the default
+command. A pin never shadows the env var, so an override in your shell still
+takes effect, and a pin that no longer parses is ignored in favor of the
+default.
+
+`deinit` deletes `.spm-injected.json`, and the pin with it. A later `add`
+therefore falls back to the default command unless you pass `--configCommand`
+(or export the env var) again.
+
+### Pinning the React Native version
+
+The resolved version selects **which artifact slots the project is wired to**,
+so it has to stay the same from one run to the next. `--version` is therefore
+recorded in the `.spm-injected.json` marker (as `artifactsVersionOverride`) and
+read back by later runs, which resolve the version in this order:
+
+1. an explicit `--version <ver>`,
+2. the version a previous `--version` pinned into the marker,
+3. `node_modules/react-native/package.json`.
+
+So you pass the flag once, and a later flagless `add`/`update` stays on the
+slots it selected. Without the pin, that flagless run falls back to
+`package.json` and re-points the project at different artifact slots while the
+marker still advertises the pinned version.
+
+`deinit` deletes the marker, and with it the pin — a later `add` resolves
+`node_modules/react-native/package.json` again unless you pass `--version`.
+
+### Debug/Release flavor is automatic
+
+React Native ships **flavored** prebuilt binaries: the _debug_ `React.framework`
+(and `hermes-engine` / `ReactNativeDependencies`) carry the dev experience — dev
+menu, assertions, `RN_DEBUG_STRING_CONVERTIBLE` — while _release_ strips them
+for production. A Debug build must embed the debug binaries and a
+Release/archive the release ones.
+
+SwiftPM `binaryTarget`s can't branch on the build configuration, so runtime
+frameworks are deliberately kept out of the package graph. `spm add` downloads
+and validates **both** flavors into immutable app-local slots. It injects
+SDK/architecture-qualified Xcode settings that link the exact selected binaries,
+plus one phase that copies and signs the selected frameworks into the app.
+Configurations containing `debug` or `development` select Debug; every other
+configuration selects Release. Selection uses only generated build settings and
+standard macOS tools: builds do not run Node, mutate symlinks, regenerate the
+package graph, or require a second build.
+
+Those same debug-flavored configurations also get
+`SWIFT_ACTIVE_COMPILATION_CONDITIONS = "$(inherited) DEBUG"` — the only thing
+that makes Swift's `#if DEBUG` true (`GCC_PREPROCESSOR_DEFINITIONS` reaches
+C/ObjC/C++ only), and what `AppDelegate.swift`'s `bundleURL()` branches on to
+load from Metro instead of a bundled `main.jsbundle`. CocoaPods injects it at
+`pod install` time, so this keeps SwiftPM apps at parity. An existing value is
+left alone.

+
+Injection is **purely additive** and **idempotent**: every other byte of your
+project — signing, capabilities, your own Build Phases — stays untouched, and a
+re-run is a no-op. The injected refs point at three stable sub-package paths
+under `build/`, so adding or removing community deps changes the sub-package
+contents (gitignored) and never re-injects. `deinit` removes exactly what was
+injected, leaving the project byte-identical to its pre-`add` state — with the
+exceptions called out above, and one more described next.
+
+**Build settings that already exist** are edited in place. The four array
+settings `add` merges into — `HEADER_SEARCH_PATHS`, `OTHER_LDFLAGS`,
+`FRAMEWORK_SEARCH_PATHS`, `LD_RUNPATH_SEARCH_PATHS` — keep the shape they were
+written in: Xcode's multi-line form as well as the compact one-line form hand
+edits and other generators (XcodeGen, Tuist) emit. One that exists as a plain
+_scalar_ is promoted to a `( … )` array — the shape an Xcode-authored target can
+carry, e.g. a
+`LD_RUNPATH_SEARCH_PATHS = "$(inherited) @executable_path/Frameworks";` written
+as a scalar rather than a list. `add` records the pre-injection value in the
+marker and `deinit` restores it by rewriting the whole field — once folded
+together, the injected members and your own are indistinguishable — so **members
+you add to a promoted array by hand afterwards are lost**. That applies to
+`update` too, which reverts to the recorded baseline before re-injecting.
+
+## Fresh clones & CI
+
+Everything under `build/` is gitignored, so a clean checkout has no resolvable
+Swift packages until they are regenerated. Xcode resolves the package graph
+before build phases **and** before scheme pre-actions, so neither
+[auto-sync hook](#auto-sync) can rescue this: with `build/generated/autolinking`
+missing, the build stops at _"Resolve Package Graph … doesn't exist"_ having run
+neither hook.
+
+Verified on Xcode 26.6 against a freshly-injected app with `build/` deleted:
+`xcodebuild -scheme … build` fails in nine lines of log, with
+`Resolve Package Graph` as the first step and no trace of the pre-action;
+`xcodebuild -resolvePackageDependencies` fails identically. Opening the project
+in Xcode also resolves the graph on load, before you press Build.
+
+So run the setup command once after cloning, before building — the SwiftPM
+analog of `pod install`:
+
+```bash
+npx react-native spm      # downloads artifacts (if missing) + regenerates build/
+```
+
+On an already-injected project this routes to `update`: it fetches the
+xcframework artifacts into the shared cache if they aren't present and
+regenerates `build/xcframeworks` + `build/generated`. After this first run,
+incremental dependency changes are picked up automatically by the auto-sync
+hooks.
+
+**Automate it** so nobody has to remember — add a `postinstall` hook, which runs
+as part of the `npm install` / `yarn install` your CI already does before
+`xcodebuild`:
+
+```json
+{
+  "scripts": {
+    "postinstall": "react-native spm"
+  }
+}
+```
+
+`npx react-native spm` auto-redirects from the JS root into `ios/`, so the hook
+works from the app root; in CI (non-interactive) it proceeds without prompting.
+It re-runs the full pipeline (codegen + an idempotent re-inject that is a no-op
+when nothing changed), so it is slightly heavier than the internal `sync` the
+build phase calls — a fine trade for not having to remember a command.
+
+> A future remote-package distribution (a tagged `Package.swift` repo +
+> `binaryTarget(url:checksum:)`) removes this step entirely: SwiftPM resolves
+> and fetches the artifacts itself during normal package resolution. Until then,
+> the one-time setup run is required on clean machines.
+
+## Local Native Modules
+
+Modules not discovered via autolinking can be declared in
+`react-native.config.js`:
+
+```js
+module.exports = {
+  spm: {
+    modules: [
+      {
+        name: 'MyNativeModule',
+        path: 'ios/MyNativeModule', // relative to app root
+        exclude: ['*.podspec'], // optional
+        publicHeadersPath: '.', // optional
+      },
+    ],
+  },
+};
+```
+
+Each entry becomes a target in `build/generated/autolinking/Package.swift`.
+Sources outside `build/generated/autolinking/` are automatically mirrored with
+file-level symlinks.
+
+## Dependencies between libraries
+
+SwiftPM has no equivalent of a podspec's `s.dependency`, so a library that needs
+another native library declares it explicitly with `spm.dependencies` in its
+**own** `react-native.config.js` — a list of npm names:
+
+```js
+// react-native-reanimated/react-native.config.js
+module.exports = {
+  dependency: {platforms: {ios: {}}},
+  spm: {dependencies: ['react-native-worklets']},
+};
+```
+
+The autolinker starts from the directly-autolinked deps, follows each one's
+`spm.dependencies` **recursively**, and dedupes the result, so a transitive
+dependency is pulled into the package graph even when the app never depends on
+it directly. Declared names are mapped to Swift target names, so the dependent
+library's target can import it.
+
+This is a **library-author** surface, like the podspec dependency it replaces —
+apps don't normally set it.
+
+## Self-managed community packages
+
+A community library that ships its own `Package.swift` is referenced directly by
+the autolinker instead of being wrapped. To keep SwiftPM's package identity
+(which it derives from the path basename) unique across deps — even when several
+libs put their manifest inside an `ios/` subdir — each self-managed dep is
+exposed through a uniquely-named symlink at
+`build/generated/autolinking/libs/<SwiftName>/`. The aggregator `Package.swift`
+references that path, so two libs both shipping `<dep>/ios/Package.swift` never
+collide on identity `"ios"`.
+
+The `libs/` directory is wiped and recreated on every autolinker run, so
+deleting a dep via `npm uninstall` cleans up the alias automatically on the next
+build.
+
+## Community packages without a Package.swift
+
+If an autolinked library ships **no `Package.swift`**, `spm add`/`update` stops
+with a per-dep error (`Package.swift is missing for library "<name>"`) and exits
+**2** — a distinct code from a generic failure, so CI and the Xcode sync hooks
+can treat it as a hard error while staying lenient about transient sync
+failures.
+
+`add` and `update` deliberately **never** scaffold on your behalf:
+auto-scaffolding would hide a real gap in the dependency's SPM support. Generate
+the manifest from the library's podspec explicitly, then re-run setup:
+
+```bash
+npx react-native spm scaffold      # writes Package.swift into node_modules/<dep>/
+npx react-native spm               # then inject/update as usual
+```
+
+(`scaffold` also runs codegen and regenerates the autolinking package, but it
+does not inject into the `.xcodeproj` — so on a first-time setup you still
+follow it with `npx react-native spm`.)
+
+Because `node_modules/` isn't committed, persist it so it survives the next
+install:
+
+```bash
+npx patch-package <dep>            # then commit the generated patch
+```
+
+**Better: contribute the manifest upstream.** The generated `Package.swift` is a
+normal, committable manifest — the ideal fix is for the library to ship it
+itself, so every consumer gets SwiftPM support without a local patch. Please
+**file an issue or open a PR on the library** with the scaffolded
+`Package.swift` (mention it was generated by `react-native spm scaffold` for
+React Native SwiftPM support). Until it lands upstream, the `patch-package`
+workaround keeps your app building.
+
+> A library whose sources mix Swift **and** Objective-C/C++ in one target, or
+> that ships neither a `Package.swift` nor a podspec, can't be scaffolded
+> automatically — the error says so. Opt it out via `react-native.config.js`
+> (`platforms.ios = null`) or ask the maintainer for a prebuilt xcframework.
+
+## Framework plugins (Preview)
+
+Frameworks with their own module system (e.g. Expo) contribute to the
+autolinking graph through a **plugin** — a function invoked on every
+regeneration (including the build-time sync) that adds SwiftPM package refs,
+product dependencies, and generated sources. Discovery is transitive (installing
+the framework is enough), and the plugin returns data that RN merges
+idempotently.
+
+See **[spm-autolinking-plugins.md](./spm-autolinking-plugins.md)** for the
+discovery mechanism, the full context/return contract, lifecycle, and failure
+behavior.
+
+## Removing / resetting
+
+To remove SwiftPM entirely, use `deinit` (the inverse of `add`):
+
+```bash
+react-native spm deinit   # surgically removes everything `add` injected
+pod install               # then, to restore CocoaPods
+```
+
+To reset the regenerable build state (without un-injecting), just delete the
+gitignored dirs and re-run:
+
+```bash
+rm -rf build/xcframeworks build/generated .build
+react-native spm update
+```
+
+Xcode's "Clean Build Folder" (Cmd+Shift+K) only removes DerivedData — it does
+not touch SwiftPM-generated directories. The cached xcframework slot is shared
+across apps; refresh it with `react-native spm update --download force`.

+
+### Header Resolution
+
+React Native uses CocoaPods-style imports (`#import <React/RCTBridge.h>`) that
+SwiftPM doesn't natively support. The prebuilt artifacts serve them through
+SwiftPM package products — no `-I` search-path flags, and no clang VFS overlay:
+
+1. **`<React/…>` and `import React`** resolve through the invariant
+   **`ReactHeaders` Clang target**. It stages one canonical header copy after
+   proving Debug and Release expose identical public headers, and uses a plain
+   `module React` module map with `React/`-prefixed paths.
+2. **Lowercase C++ `react/` and every other RN namespace** (`yoga/`, `jsi/`,
+   `jsinspector-modern`, …) comes from **`ReactNativeHeaders.xcframework`**, a
+   headers-only (LIBRARY-type) binaryTarget whose per-slice `Headers/` SwiftPM
+   auto-serves to dependents.
+3. **Third-party dependency namespaces** (`folly/`, `glog/`, `boost/`, `fmt/`,
+   `double-conversion/`, `fast_float/`, `SocketRocket/`) come from
+   **`ReactNativeDependenciesHeaders.xcframework`**, the deps headers-only
+   sidecar (same mechanism — the binary `ReactNativeDependencies.xcframework` is
+   framework-type and can't expose those headers to SwiftPM).
+
+Targets that compile against React take these as product dependencies
+(`ReactHeaders`, `ReactNativeHeaders`, `ReactNativeDependenciesHeaders`, plus
+the app's `ReactAppHeaders`), so all of the above resolve with zero search-path
+flags.
+
+### Auto-Sync
+
+Autolinking is kept up to date without manual re-runs of `react-native spm` by
+**two hooks running the same sync script**, injected by `add`/`update`:
+
+| Hook                               | Where                                                                                       | Role                                                                                                |
+| ---------------------------------- | ------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- |
+| Scheme pre-action                  | The app's **shared** scheme (`xcshareddata/xcschemes/`), under `BuildAction` → `PreActions` | Fires earlier in the build than a build phase can, so it is the one that normally does the re-sync. |
+| `Sync SPM Autolinking` build phase | `.xcodeproj`, prepended before `Sources`                                                    | **Safety net** for builds that bypass the scheme (and for a scheme whose pre-action was stripped).  |
+
+Neither hook can bootstrap a clean checkout. Xcode resolves the Swift package
+graph before build phases **and** before scheme pre-actions, so if the generated
+packages are missing entirely, resolution fails and the build stops before
+either hook runs — see [Fresh clones & CI](#fresh-clones--ci). The hooks keep an
+_existing_ set of generated packages current; they do not create the first one.
+
+**How the sync script works:**
+
+1. Compares timestamps of staleness inputs against
+   `build/generated/autolinking/.spm-sync-stamp`:
+   - `package.json` — dependency declarations
+   - `react-native.config.js` — `spm.modules` config
+   - `node_modules/` directory mtime — updated by any package manager (npm,
+     yarn, pnpm, bun); also checks parent `node_modules` for monorepo setups
+   - a missing `build/xcframeworks/` (e.g. after a manual clean) also marks
+     stale
+   - every path in `.spm-sync-watch-paths` — RN's own inputs plus any
+     [plugin](./spm-autolinking-plugins.md#watchpaths--plugin-staleness-inputs)
+     `watchPaths`; a watched file that is newer, a watched dir with a newer
+     child, or a watched path that has **vanished** all mark stale
+2. If any input is newer (or the stamp is missing): runs
+   `npx react-native spm sync`, which re-executes autolinking + package
+   generation (downloading artifacts if the cache slot is incomplete) and writes
+   the stamp file.
+3. If all inputs are fresh: exits immediately (~1ms).
+
+**Ordering.** As observed in an `xcodebuild -scheme … build` log on Xcode 26.6:
+
+| Step                                            | Owner             |
+| ----------------------------------------------- | ----------------- |
+| Resolve Package Graph                           | Xcode             |
+| **Sync SPM Autolinking**                        | scheme pre-action |
+| Prepare packages / ComputeTargetDependencyGraph | Xcode             |
+| CreateBuildDescription                          | Xcode             |
+| **Sync SPM Autolinking** (safety net)           | build phase 1     |
+| Sources (compile)                               | build phase 2     |
+| Frameworks (link)                               | build phase 3     |
+| Embed React Native Flavored Frameworks          | build phase 4     |
+| Resources (copy)                                | build phase 5     |
+| Build JS Bundle                                 | build phase 6     |
+
+Resolution coming first is what makes the one-time setup run necessary on a
+clean checkout; it is not something either hook can work around.
+
+A sync failure is lenient by default but **not unconditionally**. The generated
+script branches on the exit code:
+
+- **Exit 2** — an autolinked dependency ships no `Package.swift`. This **fails
+  the build** (`exit 1`), deliberately: the autolinker has already printed an
+  `error:` line per dep, and the fix needs a terminal (see
+  [Community packages without a Package.swift](#community-packages-without-a-packageswift)).
+- **Any other non-zero exit** — emits
+  `warning: SPM sync failed — build may use stale codegen/autolinking` and lets
+  the build continue, so an already-generated package graph can still produce a
+  successful build.
+
+That split is the whole reason the missing-manifest case has its own exit code:
+a transient sync hiccup should not break a build that could still succeed, while
+a genuinely missing manifest should not pass silently.

+ * Red tests for the transitive dependency expander.

+ *     spm: { dependencies: ['react-native-test-library-common'] },
+ *   };
+ *
+ * The expander takes the directly-autolinked deps (from autolinking.json) and
+ * follows each one's spm.dependencies recursively, resolving names to package
+ * roots via Node module resolution. Behavior mirrors podspec `s.dependency`:
+ *
+ *   - Transitive deps with iOS native code → added as autolinked targets
+ *   - Transitive deps without iOS native code → silently skipped
+ *   - Deduped by package name (first occurrence wins)
+ *   - Cycles are detected (visited set keyed on name)
+ *   - Unresolvable names throw with a clear message
+ *
+ * I/O is injected (readConfig, resolveDep) so the tests stay pure.

+ * Red tests for the SPM port of packages/react-native/scripts/cocoapods/autolinking.rb.

+ * The Ruby script (list_native_modules!) does the following:
+ *   1. Accepts a config_command (default-documented as ['npx', '@react-native-community/cli', 'config'])
+ *   2. Warns if config_command is empty / invalid (autolinking.rb:19-26)
+ *   3. Captures stdout + exit status of the command (autolinking.rb:28)
+ *   4. Warns if exit status is non-zero (autolinking.rb:30-37)
+ *   5. Parses the JSON output (autolinking.rb:38)
+ *   6. Derives output path = <config.project.ios.sourceDir>/build/generated/autolinking/autolinking.json (autolinking.rb:41-43)
+ *   7. Creates the output directory if missing (autolinking.rb:46)
+ *   8. Writes the RAW JSON string unchanged to that path (autolinking.rb:47)
+ *
+ * These tests assert the same surface for the JS port (generate-spm-autolinking-config.js),
+ * which does not yet exist — so they are red by construction.

+/**
+ * SwiftPM autolinking plugins — the extension seam for frameworks (Expo first)
+ * that need to contribute their own SwiftPM package refs / product deps /
+ * generated sources into the autolinked package graph.
+ *
+ * PREVIEW / UNSTABLE CONTRACT. The discovery mechanism and the plugin
+ * function's context/return shape may change while the first real consumers
+ * (Expo) validate it.
+ *
+ * Why a plugin and not a post-process: the Xcode auto-sync build phase
+ * re-runs autolinking on every dependency change, so a one-shot rewrite of the
+ * generated Package.swift is clobbered on the next sync. Plugins are invoked
+ * from generate-spm-autolinking.js:main() — the single function both `add`/
+ * `update` and the build-time `sync` call — so a contribution runs on EVERY
+ * regeneration.
+ *
+ * Discovery (transitive, mirrors CocoaPods' `use_expo_modules!`): any
+ * autolinked dependency can register a plugin from its own
+ * react-native.config.js —
+ *
+ *     // node_modules/expo/react-native.config.js
+ *     module.exports = { spm: { autolinkingPlugin: './spm/plugin.js' } };
+ *
+ * Installing the framework is enough; no app-level config is required. An app
+ * MAY still exclude a plugin via `spm.denyPlugins` (npm-name list) in its own
+ * react-native.config.js — an escape hatch, not a required allowlist.
+ *
+ * Contract:
+ *
+ *     module.exports = function plugin(context) {
+ *       // context: {appRoot, projectRoot, reactNativeRoot, autolinking,
+ *       //           outputDir, react}
+ *       // context.react (?ReactDescriptor): how to depend on React —
+ *       //   {packageRef, products}. packageRef is local ({name, path (absolute),
+ *       //   relPath}) or remote ({name, url, version}); products is the set RN
+ *       //   gives its own autolinked targets (incl. ReactAppHeaders from the
+ *       //   separate React-GeneratedCode package), filtered to what resolves
+ *       //   this run. Use it instead of re-deriving RN's path/identity/products.
+ *       return {
+ *         packageDependencies: [{name, path}] | [{name, url, version}],
+ *         productDependencies: [{name, package}],
+ *         // Sources compiled INTO THE APP TARGET (not the static Autolinked
+ *         // aggregate) — the only place an @objc class reaches the ObjC
+ *         // classlist, so emit files here when a class must be reachable by
+ *         // name (e.g. via NSClassFromString), as Expo's ExpoModulesProvider
+ *         // needs. Recorded to `.spm-plugin-generated-sources.json`; the
+ *         // `spm add`/`update` xcodeproj injector wires each into the app
+ *         // target (PBXFileReference + Sources-phase entry), marker-tracked
+ *         // so deinit reverts and update reconciles.
+ *         generatedSources: [{path}],
+ *         // Precompiled dynamic frameworks selected and embedded by RN outside
+ *         // the SwiftPM graph. Both flavors are mandatory.
+ *         flavoredFrameworks: [{id, frameworkName, linkage: 'dynamic',
+ *           flavors: {debug, release}}],
+ *         // Absolute paths (dirs OR files) the Xcode auto-sync build phase
+ *         // should watch for staleness — e.g. the plugin dep's own
+ *         // `Package.swift`, `expo-module.config.json`, and per-module
+ *         // manifests. Folded into `.spm-sync-watch-paths`; a file edit or a
+ *         // dir add/remove there re-triggers the sync. Relative/empty/non-string
+ *         // entries are dropped with a warning; a non-array is ignored.
+ *         watchPaths: ['/abs/path/Package.swift', '/abs/dir'],
+ *         // Build-time shell phases on the app target — SwiftPM has no
+ *         // `script_phase`. Only id/name/script are required; `id` is the
+ *         // ledger key and UUID seed, `position` defaults to 'end'. Recorded
+ *         // to `.spm-plugin-script-phases.json`, from which the `spm add`/
+ *         // `update` injector emits a PBXShellScriptBuildPhase per entry.
+ *         // Malformed entries and duplicate ids are fatal.
+ *         scriptPhases: [{id, name, script, position, inputPaths, outputPaths,
+ *           alwaysOutOfDate}],
+ *       };
+ *     };
+ *
+ * The plugin returns DATA; it never writes into RN's generated tree. RN owns
+ * the merge, so regeneration stays deterministic and idempotent.

+/**
+ * download-spm-artifacts.js
+ *
+ * Downloads the three React Native iOS xcframeworks from Maven, extracts
+ * them to a local cache directory, and writes artifacts.json for use by
+ * generate-spm-package.js.
+ *
+ * Supports stable releases, nightlies, and snapshot builds, matching
+ * the same resolution logic used by the existing CocoaPods scripts.
+ *
+ * Artifacts handled:
+ *   React                  – react-native-core tarball from Maven
+ *   ReactNativeDependencies – react-native-dependencies tarball from Maven
+ *   hermes-engine          – hermes-ios tarball from Maven
+ *
+ * Usage:
+ *   node scripts/download-spm-artifacts.js [options]
+ *
+ * Options:
+ *   --version <ver>    RN version. Defaults to version in package.json.
+ *                      Use "nightly" to resolve the latest nightly.
+ *   --flavor  <f>      debug (default) or release.
+ *   --output  <dir>    Where to write xcframeworks.
+ *                      Default: ~/Library/Caches/ReactNative/spm-artifacts/{version}/{flavor}/
+ *                      (downloaded tarballs are shared with CocoaPods in
+ *                      ~/Library/Caches/ReactNative/; RCT_SKIP_CACHES=1 bypasses.)
+ *
+ * Per-artifact version overrides (mirrors existing env vars):
+ *   HERMES_VERSION=<ver|nightly|latest-v1>
+ *   RN_DEP_VERSION=<ver|nightly>
+ *
+ * Repository selection:
+ *   Release tarballs are looked up on the React Native Maven mirror first,
+ *   with Maven Central as the fallback when the mirror doesn't have the
+ *   artifact (or errors). Nightlies/snapshots always come from Sonatype.
+ *   ENTERPRISE_REPOSITORY=<url>   Custom Maven repository (must match the
+ *                                 Maven structure). When set it is the ONLY
+ *                                 repository consulted (no mirror/Central).
+ *   RCT_REACT_NATIVE_MAVEN_MIRROR_ENABLED=false|0
+ *                                 Skip the mirror and go straight to Maven
+ *                                 Central.
+ *
+ * Output:
+ *   <output>/React.xcframework/
+ *   <output>/ReactNativeDependencies.xcframework/
+ *   <output>/hermes-engine.xcframework/
+ *   <output>/artifacts.json        ← maps target names to xcframework paths

+ *
+ * Invokes the React Native community CLI to produce its config and writes the
+ * raw JSON to <project.ios.sourceDir>/build/generated/autolinking/autolinking.json.
+ * The config command can be overridden by `--config-command` or
+ * `RCT_SPM_AUTOLINKING_CONFIG_COMMAND`, in that order, before the default.

+ * No filtering or reshaping happens here — the downstream consumer
+ * (generate-spm-autolinking.js) does its own iOS-only filtering when reading

+ * generate-spm-autolinking.js – Generates autolinked/Package.swift, the SPM
+ * equivalent of CocoaPods' `use_native_modules!`.
+ *
+ * Usage:
+ *   node generate-spm-autolinking.js [options]
+ *
+ * Options:
+ *   --app-root <path>            Path to the app directory (default: cwd)
+ *   --react-native-root <path>   Path to react-native package root
+ *   --autolinking-json <path>    Path to autolinking.json (default: build/generated/autolinking/autolinking.json)
+ *   --output <path>              Output dir (default: autolinked/)
+ *
+ * Reads:
+ *   - build/generated/autolinking/autolinking.json (produced by react-native codegen)
+ *   - react-native.config.js (for spm.modules extra modules, optional)
+ *
+ * Generates:
+ *   - autolinked/Package.swift
+ *
+ * V1 behavior:
+ *   - Processes npm-package native modules with platforms.ios != null from autolinking.json
+ *   - Also processes any `spm.modules` entries from react-native.config.js for local modules
+ *   - Targets resolve React headers via SPM product dependencies (no flags)
+ *
+ * V2 behavior (future):
+ *   - npm packages with their own Package.swift use .package(url: ...) instead of inline targets

+
+// Bump when the emitter's output format changes in a way that requires
+// re-scaffolding existing files (rather than just being a content drift the
+// cache-slot label already handles). v2: swift-tools-version moved to
+// line 1 — pre-v2 scaffolds emit it on a later line, which recent Xcode
+// rejects with "Swift tools version 3.1.0 ... no longer supported". v4: the
+// single `let rnHeaders = appRoot + "/.../ReactHeadersAll"` split into the two
+// `rnCoreHeaders` / `appHeaders` lets (merged tree replaced by two trees), so
+// pre-v4 scaffolds reference a tree that is no longer materialized. v5:
+// header resolution moved to product dependencies (ReactNativeHeaders +
+// ReactAppHeaders binary/headers targets) — the rnCoreHeaders/appHeaders
+// trees no longer exist, so pre-v5 scaffolds carry dead lets and would break
+// if anything still referenced them. v7: the runtime appRoot walker and the
+// siblingPath helper are gone — package paths are plain relative strings
+// computed at scaffold time (the walker anchored on
+// build/xcframeworks/Package.swift, which remote mode no longer writes).
+//
+// Skip-rule contract: when an existing file's version is < this constant,
+// the scaffolder regenerates regardless of --force (the bump implies the
+// existing file is broken under current tooling). A file with the marker
+// but no version line is treated as v1.
+// v8: relative app paths (codegen / xcframeworks) are now computed from the
+// autolinker's libs/<SwiftName> symlink location instead of the real dep.root,
+// fixing a doubled-path resolution failure on fresh SwiftPM resolves.
+// v9: header search paths derived from each subspec's header_mappings_dir
+// (dirname) so namespaced includes (`<reanimated/...>`) resolve. v10:
+// publicHeadersPath derived from the header_mappings_dir namespace root so a
+// package exposes `<namespace/...>` to dependents; pod-style sibling deps
+// (reanimated's `s.dependency "RNWorklets"`) wired to their npm package. v11:
+// sibling .package path uses the libs/<SwiftName> symlink name, not the npm
+// name (fixes "package ... doesn't exist" on resolve). v12: preprocessor
+// defines from pod_target_xcconfig emitted as `.define(...)`. v13: ObjC(++)
+// targets get an ambient-import prefix header (Foundation/UIKit) `-include`d,
+// replacing CocoaPods' generated prefix.pch. v18: React-core deps also get
+// the ReactNativeDependenciesHeaders product (ReactNativeHeaders went
+// pure-RN; folly/glog/boost/... now come from the deps sidecar);

+ * sync-spm-autolinking.js – Lightweight script invoked by the Xcode pre-build
+ * phase to re-run invariant codegen and autolinking output when dependency
+ * inputs have changed.
+ *
+ * Usage (called from the Xcode build phase shell script):
+ *   node sync-spm-autolinking.js --app-root <path> --react-native-root <path>
+ *
+ * The autolinking config (autolinking.json) is generated by the caller
+ * (setup-apple-spm.js) BEFORE this script runs, so codegen below can reuse it
+ * (findCodegenEnabledLibraries short-circuits on a present autolinking.json)
+ * and the slow `@react-native-community/cli config` runs exactly once per sync.
+ *
+ * This script:
+ *   0. Runs react-native codegen → build/generated/ios/ (reuses autolinking.json)
+ *   1. Installs the codegen template into build/generated/ios/Package.swift,
+ *      replacing codegen's mis-rooted default (done immediately, before any
+ *      step below that can throw — see the failure-atomicity comment at the
+ *      call site)
+ *   2. Calls generate-spm-autolinking.js → build/generated/autolinking/Package.swift
+ *   3. Rebuilds the generated-headers farm
+ *   4. Writes build/generated/autolinking/.spm-sync-stamp
+ *
+ * Runtime frameworks are deliberately not downloaded or regenerated from an
+ * Xcode build. `spm add` / `spm update` own the immutable dual-flavor slots and
+ * the app target's linker/embed configuration.

+# ResizeObserver
+
+[🏠 Home](../../../../../../../__docs__/README.md)
+
+This directory contains the React Native implementation of the
+[ResizeObserver API](https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserver).
+
+## 🚀 Usage
+
+`ResizeObserver` is meant to be used from JavaScript, exposed as a global class.
+
+## 📐 Design
+
+This is the high-level design of the ResizeObserver API:
+
+![ResizeObserver architecture design](./architecture.excalidraw.png)
+
+The global `ResizeObserver` class is defined in JavaScript and it does its setup
+using a native module.
+
+In native, it relies on commit hooks from `UIManager` to learn which nodes had
+layout updates after each commit (`shadowTreeDidCommit` with the affected layout
+nodes). The commit hook records which observed targets may have resized. A
+dedicated step in the Event Loop (as specified in the Web spec, via
+`RuntimeSchedulerResizeObserverDelegate`) then runs resize observations against
+the latest committed tree and notifies JavaScript when there are pending
+entries. JavaScript pulls those entries via `takeRecords` and dispatches them to
+the right observers.
+
+Unlike layout events (`onLayout`), `ResizeObserver` lets callers choose which
+box to observe (`content-box`, `border-box`, or `device-pixel-content-box`) and
+delivers sizes for those boxes in the notification. Notifications are delivered
+from the «update the rendering» step of the Event Loop (via
+`RuntimeSchedulerResizeObserverDelegate`) — after the task that committed the
+layout change and that task's microtask checkpoint, not synchronously when
+layout is computed.
+

+//
+// This is a secondary entry point for frameworks and libraries that depend on
+// specific React Native internals, serving as a compatibility bridge.
+//
+// Consuming codebases must opt in via tsconfig.json:
+//   "customConditions": ["react-native-unstable-internals"]
+//
+// Having this entry point:
+// - Maintains a known list of which React Native internals are in use.
+// - Enables us to relocate supporting files more freely.
+// - Gives us time to decide on the future of these APIs (independent from
+//   removal of the Strict API opt out).
+//
+// The long term future of these exports is to formalize/delete them where
+// appropriate, and collapse this entry point.
+//
+// Replaces RFC0985
+// https://github.com/react-native-community/discussions-and-proposals/pull/985
+// where we reviewed internal APIs used in the ecosystem.
+//
+// IMPORTANT: Keep this file in sync with unstable-internals-do-not-use.d.ts.

 This package provides the default `tsconfig.json` used by newly built React Native apps.
 
 This template is customized for specific versions of React Native, and should be updated in sync with the rest of your app.
 
-## Strict TypeScript API
+## Opting out of the Strict TypeScript API (default in 0.87)
 
-To opt into the new [strict TypeScript API](https://reactnative.dev/blog/2025/06/12/moving-towards-a-stable-javascript-api#strict-typescript-api-opt-in) you can extend from `@react-native/typescript-config/strict`
-
-```jsonc
-{

-  // ...
-}
-```
+To opt out of the new [Strict TypeScript API](https://reactnative.dev/docs/strict-typescript-api) you can extend from `@react-native/typescript-config/strict`
 
-or alternatively add the `customConditions` yourself:
+If your app still needs access to deep `'react-native/Libraries/*'` imports (deprecated in 0.80), you can opt out via `customConditions` in your `tsconfig.json`:
 
 ```jsonc
 {
   "extends": "@react-native/typescript-config",
   "compilerOptions": {
     // ...
-    "customConditions": ["react-native-strict-api", "react-native"]
+    "customConditions": ["react-native", "react-native-legacy-deep-imports"]
   }
 }

+# maintainVisibleContentPosition Design and Architecture
+
+## 1. Overview
+
+### 1.1 Purpose
+
+`maintainVisibleContentPosition` (MVCP) is a React Native prop on `ScrollView`
+and `FlatList` that prevents unwanted scroll jumps when items are prepended to a
+list. When new items are added at the beginning of a list, MVCP computes a
+scroll delta correction to keep the previously visible content at the same
+screen position.
+
+### 1.2 What Problem It Solves
+
+Without MVCP, prepending items to a scrollable list causes all existing content
+to shift downward visually — the scroll offset remains the same but the user's
+visible content changes. This creates a jarring UX where the user loses their
+place in the list. MVCP compensates by adjusting `contentOffset` by the same
+amount that the anchor view shifted, keeping the visible content locked to the
+same screen position.
+
+### 1.3 Scope
+
+- **Components:** `ScrollView` (iOS Fabric, Android), `FlatList` (via
+  ScrollView)
+- **Operations handled:** Prepends, appends, deletes, item updates, size changes
+- **Axes:** Vertical and horizontal lists
+- **Modes:** Normal and inverted lists
+- **Layers:** JS (detection), Native iOS Fabric, Native Android
+
+**Note:** iOS Paper (Legacy) MVCP implementation was removed in June 2026
+(commit `86350ab9884`, PR #56831). Only iOS Fabric and Android retain MVCP
+support.
+
+---
+
+## 2. Architecture Overview
+
+### 2.1 High-Level Design
+
+MVCP follows a **three-layer split** between JS and native:
+
+```text
+┌──────────────────────────────────────────────────────────┐
+│  JS Layer (VirtualizedList / ScrollView)                 │
+│  - Detects prepends via firstVisibleItemKey comparison   │
+│  - Tracks pendingScrollUpdateCount                       │
+│  - Suppresses render window updates during correction    │
+│  - Forwards maintainVisibleContentPosition prop to native│
+└────────────────────────┬─────────────────────────────────┘
+                         │ prop: {minIndexForVisible, autoscrollToTopThreshold}
+┌────────────────────────▼────────────────────────────────┐
+│  Native Layer (per-platform)                            │
+│  ┌─────────────┐  ┌────────────────┐                    │
+│  │ iOS Fabric  │  │   Android      │                    │
+│  │ Mounting    │  │ UIManager      │                    │
+│  │ Transaction │  │ Listener       │                    │
+│  │ Callbacks   │  │ Callbacks      │                    │
+│  └─────────────┘  └────────────────┘                    │
+│                                                         │
+│  Core algorithm (all platforms):                        │
+│  1. Capture anchor view frame before mount              │
+│  2. Apply mutations (insert, remove, update)            │
+│  3. Compute delta = newFrame - oldFrame                 │
+│  4. Apply delta to contentOffset                        │
+│                                                         │
+│  Anchor recomputation happens in the next cycle's       │
+│  WILL_MOUNT phase, not in DID_MOUNT.                    │
+└─────────────────────────────────────────────────────────┘
+```
+
+### 2.2 Core Algorithm: Frame Delta Correction
+
+All platforms implement the same fundamental algorithm:
+
+```text
+delta = anchorFrameAfterMount - anchorFrameBeforeMount
+contentOffset += delta
+```
+
+Frames are **snapshots**, not live references. Once captured, frame values don't
+change even if the view is later moved or removed. This makes the approach safe
+across all platforms.
+
+---
+
+## 3. Key Components
+
+### 3.1 JS Layer
+
+#### 3.1.1 VirtualizedList (`packages/virtualized-lists/Lists/VirtualizedList.js`)
+
+**Responsibilities:**
+
+- Detects prepends by comparing `firstVisibleItemKey` across renders
+- Computes `maintainVisibleContentPositionAdjustment` (prepend delta in item
+  count)
+- Increments `pendingScrollUpdateCount` to suppress render window updates
+- Adjusts `cellsAroundViewport` render window by the adjustment amount
+
+**Key state field:** `pendingScrollUpdateCount` — dual-purpose:
+
+1. Initial scroll index tracking (set to `1` when `initialScrollIndex > 0`)
+2. MVCP adjustment tracking (incremented on prepend detection, decremented on
+   scroll events)
+
+**Detection flow (in `getDerivedStateFromProps`):**
+
+```js
+// When maintainVisibleContentPosition != null:
+if (firstVisibleItemKey changed between renders) {
+    // Item was prepended — find where the previous anchor is now
+    newAdjustment = firstVisibleItemIndex - minIndexForVisible
+    cellsAroundViewport shifted by adjustment
+    pendingScrollUpdateCount++
+}
+```
+
+**Guard interactions:**
+
+- `_adjustCellsAroundViewport`: Returns early when
+  `pendingScrollUpdateCount > 0`, preventing render window updates during MVCP
+  corrections
+- `_maybeCallOnEdgeReached`: Suppresses edge callbacks while
+  `pendingScrollUpdateCount > 0`
+
+#### 3.1.2 ScrollView (`packages/react-native/Libraries/Components/ScrollView/ScrollView.js`)
+
+**Responsibilities:**
+
+- Passes `maintainVisibleContentPosition` prop through to native component
+- Sets `collapsableChildren = true` when MVCP is active, preventing React from
+  collapsing/merging child views — critical for stable native view references
+
+**Prop type:**
+
+```js
+maintainVisibleContentPosition?: ?{
+  minIndexForVisible: number,
+  autoscrollToTopThreshold?: ?number,
+}
+```
+
+#### 3.1.3 ListMetricsAggregator (`packages/virtualized-lists/Lists/ListMetricsAggregator.js`)
+
+**Responsibilities:**
+
+- Tracks cell layout metrics for approximate sizing
+- Clears metrics on orientation change (prevents stale metric corruption)
+- Guards against divide-by-zero in `_averageCellLength` computation
+
+**Key state:**
+
+- `_cellMetrics: Map<string, CellMetrics>` — per-cell layout info
+- `_measuredCellsCount: number` — count of measured cells
+- `_averageCellLength: number` — computed average, guarded by `if (count > 0)`
+
+### 3.2 iOS Fabric Layer
+
+#### 3.2.1 RCTScrollViewComponentView (`RCTScrollViewComponentView.mm`)
+
+**Mounting transaction callbacks:**
+
+- `mountingTransactionWillMount:` — triggers
+  `_prepareForMaintainVisibleScrollPosition`
+- `mountingTransactionDidMount:` — triggers `_remountChildren` then
+  `_adjustForMaintainVisibleContentPosition`
+
+**Core methods:**
+
+- `_prepareForMaintainVisibleScrollPosition` — recomputes anchor before mount;
+  scans subviews to find first visible view
+- `_adjustForMaintainVisibleContentPosition` — computes delta, applies
+  correction
+
+**State variables:**
+
+| Variable                                            | Type              | Purpose                                    |
+| --------------------------------------------------- | ----------------- | ------------------------------------------ |
+| `_prevFirstVisibleFrame`                            | `CGRect`          | Captured frame of anchor before mount      |
+| `_firstVisibleView`                                 | `__weak UIView *` | Reference to current first visible subview |
+| `_firstVisibleViewTag`                              | `NSInteger`       | Tag for recycle detection                  |
+| `_avoidAdjustmentForMaintainVisibleContentPosition` | `BOOL`            | Skip gate for immediate update mode        |
+
+**Tag comparison safeguard:**
+
+```objc
+// Abort if the first visible view has been recycled for a different item.
+// The tag was captured in _prepareForMaintainVisibleScrollPosition (before
+// mounting), and RCTComponentViewRegistry assigns new tags during dequeue
+// (mounting) and resets them to 0 during enqueue (unmounting). When items
+// are removed and re-added, recycled views get new tags based on their
+// position, so the view at position 0 may have a different tag than before.
+// If the tag changed, we bail out to avoid applying the MVCP delta to the
+// wrong view, which would produce incorrect scroll offsets.
+if (_firstVisibleView.tag != _firstVisibleViewTag) {
+    return;  // View was recycled - abort correction
+}
+```
+
+**Status:** Always active. `RCTComponentViewRegistry` assigns tags during
+dequeue (`componentViewDescriptor.view.tag = tag`) and resets to 0 during
+enqueue (`componentViewDescriptor.view.tag = 0`). When items are removed and
+re-added, recycled UIViews get new tags based on their position. The view at
+position 0 may have a different tag than before, so the check must always run.
+
+#### 3.2.2 RCTComponentViewRegistry (`RCTComponentViewRegistry.mm`)
+
+**Recycle pool mechanics:**
+
+- Pool size: 1024 views per component type
+- **Enqueue:** Delete mutations -> `prepareForRecycle()` -> push to pool
+- **Dequeue:** Create mutations -> pop from pool -> set new tag -> register
+- **Memory pressure:** Clears entire pool on `didReceiveMemoryWarning`
+
+### 3.3 Android Layer
+
+#### 3.3.1 MaintainVisibleScrollPositionHelper (`MaintainVisibleScrollPositionHelper.kt`)
+
+**Class signature:**
+
+```kotlin
+internal class MaintainVisibleScrollPositionHelper<ScrollViewT>(
+    private val scrollView: ScrollViewT,
+    private val horizontal: Boolean,
+) : UIManagerListener where ScrollViewT : HasSmoothScroll?, ScrollViewT : ViewGroup?
+```
+
+**State variables:**
+
+| Variable                | Type                   | Purpose                                        |
+| ----------------------- | ---------------------- | ---------------------------------------------- |
+| `config`                | `Config?`              | MVCP configuration                             |
+| `firstVisibleViewRef`   | `WeakReference<View>?` | Anchor view reference (auto-nullifies if GC'd) |
+| `prevFirstVisibleFrame` | `Rect?`                | Captured frame of anchor                       |
+| `isListening`           | `boolean`              | Whether listener is active                     |
+
+**Lifecycle callbacks:**
+
+- `willDispatchViewUpdates` — calls `computeTargetView()` (pre-layout, first
+  capture)
+- `willMountItems` — calls `computeTargetView()` (pre-layout, second capture)
+- `didMountItems` — calls `updateScrollPositionInternal()`
+
+**`computeTargetView`:**
+
+- Iterates from `config.minIndexForVisible` through `contentView.childCount`
+- Selects first child where `position > currentScroll` or the last child
+- Stores `WeakReference(child)` in `firstVisibleViewRef`
+- Captures `child.getHitRect(frame)` into `prevFirstVisibleFrame`
+
+**`updateScrollPositionInternal`:**
+
+- Retrieves cached `firstVisibleViewRef` and `prevFirstVisibleFrame` (captured
+  by `willMountItems`)
+- Computes delta on `left` (horizontal) or `top` (vertical) coordinates
+- `scrollToPreservingMomentum()`
+- Updates `prevFirstVisibleFrame` to new frame after correction
+- Calls `emitScrollEventNoThrottle()` to ensure JS state is current
+- Early return if `firstVisibleViewRef.get()` is null (view GC'd)
+- **Threshold:** Uses `delta != 0` (vs iOS `ABS(delta) > 0.5`)
+
+#### 3.3.2 ReactScrollView (`ReactScrollView.java`)
+
+**MVCP field:**
+
+```java
+private @Nullable MaintainVisibleScrollPositionHelper mMaintainVisibleContentPositionHelper;
+```
+
+**`setMaintainVisibleContentPosition`:**
+
+- `config != null && helper == null`: creates new helper with
+  `horizontal = false`, calls `start()`
+- `config == null && helper != null`: calls `stop()`, sets helper to `null`
+- Helper exists: updates config via `setConfig()`
+
+**`horizontal` flag:** Hardcoded to `false` — `ReactScrollView` only supports
+vertical scrolling.
+
+**Lifecycle integration:**
+
+- `onAttachedToWindow`: calls `helper.start()`
+- `onDetachedFromWindow`: calls `helper.stop()`
+
+#### 3.3.3 ReactViewGroup Content Culling (`ReactViewGroup.kt`)
+
+**Culling mechanism:**
+
+- `allChildren` array: stores ALL children (visible + culled) for O(1)
+  re-addition
+- `removeClippedSubviews` boolean: enables culling
+- Off-screen children: `removeViewInLayout()` — detached but kept in
+  `allChildren`
+- On-screen children: `addViewInLayout()` — re-attached from `allChildren`
+
+**MVCP interaction:** `computeTargetView` iterates `contentView.childCount`
+(visible children only, not `allChildrenCount`), meaning culling affects anchor
+candidate selection.
+
+---
+
+## 4. Events & Lifecycle
+
+### 4.1 Mount Cycle Events
+
+Both active platforms follow the same high-level pattern:
+
+```text
+1. WILL_MOUNT (before mutations):
+    - Capture anchor view's frame -> prevFirstVisibleFrame
+   - Store anchor view reference -> firstVisibleView
+
+2. MOUNT (mutations applied):
+   - New items inserted, existing items shifted
+   - Layout computed, frames updated
+
+3. DID_MOUNT (after mutations):
+   - Compute delta = (anchor's frame now) - (captured frame)
+   - Apply delta to contentOffset
+
+Anchor recomputation happens in the next cycle's WILL_MOUNT phase, not in DID_MOUNT.
+```
+
+#### 4.1.1 iOS Fabric Event Flow
+
+```text
+RCTMountingManager.performTransaction:
+  |
+  +-- _observerCoordinator.notifyObserversMountingTransactionWillMount
+  |      -> RCTScrollViewComponentView.mountingTransactionWillMount
+  |         -> _prepareForMaintainVisibleScrollPosition
+  |            -> Scan _contentView.subviews from minIndexForVisible
+  |            -> Find first partially visible subview
+  |            -> Store: _firstVisibleView, _firstVisibleViewTag, _prevFirstVisibleFrame
+  |
+  +-- RCTPerformMountInstructions (mutations applied)
+  |      Create: dequeue from RCTComponentViewRegistry
+  |      Delete: enqueue to RCTComponentViewRegistry
+  |      Update: update existing views
+  |
+  +-- _observerCoordinator.notifyObserversMountingTransactionDidMount
+  |      -> RCTScrollViewComponentView.mountingTransactionDidMount
+  |         -> _remountChildren (no-op when enableViewCulling is true;
+  |            calls updateClippedSubviewsWithClipRect when false)
+  |         -> _adjustForMaintainVisibleContentPosition
+  |            -> Tag comparison check (always active)
+  |            -> delta = _firstVisibleView.frame - _prevFirstVisibleFrame
+  |            -> Abort if ABS(delta) <= 0.5
+  |            -> contentOffset += delta
+  |            -> autoscrollToTopThreshold check (animate to start if near top)
+```
+
+#### 4.1.2 Android Event Flow
+
+```text
+SurfaceMountingManager.onBatchComplete:
+  |
+  +-- UIManagerImplementationExecutor.notifyWillDispatchViewUpdates
+  |      -> MaintainVisibleScrollPositionHelper.willDispatchViewUpdates
+  |         -> computeTargetView() [pre-layout, first capture]
+  |
+  +-- UIManagerImplementationExecutor.notifyWillMountItems
+  |      -> MaintainVisibleScrollPositionHelper.willMountItems
+  |         -> computeTargetView() [pre-layout, second capture, overwrites first]
+  |
+  +-- View mount / layout updates
+  |      Children added/removed from contentView
+  |      UPDATE_LAYOUT: view.measure() + view.layout() — frames set here
+  |      Culling: off-screen children removed from children (kept in allChildren)
+  |
+  +-- UIManagerImplementationExecutor.notifyDidMountItems
+  |      -> MaintainVisibleScrollPositionHelper.didMountItems
+  |         -> updateScrollPositionInternal()
+  |            -> firstVisibleView = firstVisibleViewRef.get()
+  |            -> if firstVisibleView != null:
+  |            ->    delta = firstVisibleView.frame - prevFirstVisibleFrame
+  |            ->    if delta != 0: scrollToPreservingMomentum(currentScroll + delta)
+  |            ->    Update prevFirstVisibleFrame to new frame
+  |            ->    emitScrollEventNoThrottle()
+```
+
+### 4.2 Scroll Events
+
+**JS-side scroll event handling (`_onScroll` in VirtualizedList):**
+
+```js
+if (this.state.pendingScrollUpdateCount > 0) {
+  this.setState({pendingScrollUpdateCount: state.pendingScrollUpdateCount - 1});
+}
+```
+
+Each scroll event decrements `pendingScrollUpdateCount`. When it reaches 0,
+render window updates resume and edge callbacks are re-enabled.
+
+### 4.3 Observer Registration Lifecycle
+
+| Platform   | Registration Trigger                                                                  | Deregistration Trigger                                               |
+| ---------- | ------------------------------------------------------------------------------------- | -------------------------------------------------------------------- |
+| iOS Fabric | `mountingTransactionWillMount` callback (automatic via observer coordinator)          | `mountingTransactionDidMount` callback                               |
+| Android    | `setMaintainVisibleContentPosition:` config != null (creates helper, calls `start()`) | `setMaintainVisibleContentPosition:` config == null (calls `stop()`) |
+
+---
+
+## 5. Code Flows
+
+### 5.1 Normal Operation — Single Prepend
+
+```text
+User scrolls to item 5 (offset = 500)
+  |
+  v
+JS renders: [X, A, B, C, D, E, F, G, H]  (prepend 1 item)

+  v
+VirtualizedList detects firstVisibleItemKey changed

+Native: contentOffset += 50 -> offset = 550
+Native: Anchor stays at same screen position (550 - 550 = 0, top of viewport)
+  |
+  v
+Next cycle's WILL_MOUNT: Recompute anchor for next correction
+JS: Scroll event fires -> pendingScrollUpdateCount decrements
+JS: Render window updates resume
+```
+
+### 5.2 Rapid Consecutive Prepends
+
+```text
+First prepend:
+  _prepare (pre-mount):   capture A at y=0  [stale frame, pre-layout]
+  mount + layout:         A moves to y=100  [frames updated]
+  _adjust:                delta = 100 - 0 = 100, offset = 100
+
+Second prepend:
+  _prepare (pre-mount):   capture A at y=100  [stale frame, but from correct layout pass]
+  mount + layout:         A moves to y=200
+  _adjust:                delta = 200 - 100 = 100, offset = 200
+
+Why this works:
+  _prepare runs BEFORE layout blocks fire, so it always captures
+  a stale frame from the previous layout pass. The delta is computed
+  as (post-layout frame) - (pre-layout frame), which correctly
+  represents the frame shift caused by the mount.
+
+  The _prepare capture for batch N+1 uses the frame that was captured
+  by _prepare in batch N (which was stale from N-1's layout). But
+  since the delta is computed from the ACTUAL post-layout frame
+  minus that captured frame, the delta is still correct.
+
+Additional role: anchor re-selection
+  If the correction pushed A off-screen, the next _prepare finds the new
+  first visible view (e.g., B). The next _prepare then anchors to B instead of
+  the now-invisible A. Without recomputation, stale frame data from the wrong view would
+  be used for the next correction.
+```
+
+### 5.3 View Recycling — iOS Fabric
+
+```text
+Initial state: [A, B, C, D, E], anchor = B at y=100
+  _firstVisibleView = vB, _firstVisibleViewTag = 101
+  _prevFirstVisibleFrame = {y: 100}
+
+User removes A, adds X at top: [X, B, C, D, E]
+  Differ generates: Delete A, Create X, Update B,C,D,E
+
+Delete A: vA.tag = 0 -> enqueue to recycle pool
+Create X: dequeue vA from pool -> set vA.tag = 200 (X's tag)
+          SAME UIView object, NEW tag
+
+Mount: B moves to index 1, frame.y = 150
+  _firstVisibleView still points to vB (same object, tag unchanged)
+
+Tag check:
+  _firstVisibleView.tag (101) != _firstVisibleViewTag (101) -> PASS
+  (Tag check would fail if _firstVisibleView was recycled)
+
+delta = 150 - 100 = 50
+contentOffset += 50
+```
+
+**Bug scenario when anchor is recycled:** If the anchor view itself happens to
+be recycled (deleted and recreated with a new tag), the tag comparison detects
+the mismatch and aborts the correction. The next batch will recompute and
+correct from fresh data.
+
+> **Important:** The tag check is **always active** (no feature flag gate).
+> `RCTComponentViewRegistry` assigns tags during dequeue and resets to 0 during
+> enqueue. When items are removed and re-added, recycled UIViews get new tags
+> based on their position. The view at position 0 may have a different tag than
+> before, so the check must always run. This was confirmed by the
+> `flatlist-inverted-recycle-maintainvisible` maestro test, which failed when
+> the tag check was gated behind `enableViewCulling()` (which returns false in
+> RNTester).
+
+### 5.4 Empty List / Data Reset
+
+**iOS Fabric (minor bug):** When the list becomes empty,
+`_prepareForMaintainVisibleScrollPosition` doesn't execute (loop doesn't run),
+leaving `_firstVisibleView` unchanged. When
+`_adjustForMaintainVisibleContentPosition` runs, it accesses
+`_firstVisibleView.frame` — in Objective-C, accessing `.frame` on nil returns
+`{0,0}`, so `deltaY = 0 - _prevFirstVisibleFrame.origin.y` causes an incorrect
+scroll correction.
+
+**Android (safe):** `updateScrollPositionInternal` checks
+`firstVisibleViewRef.get() ?: return` — early return if view is null. No
+incorrect correction.
+

+
+## 6. State Management
+
+### 6.1 State Variables by Platform
+
+| Variable              | iOS Fabric                                          | Android                               |
+| --------------------- | --------------------------------------------------- | ------------------------------------- |
+| Anchor view reference | `_firstVisibleView` (UIView\*)                      | `firstVisibleViewRef` (WeakReference) |
+| Anchor view tag       | `_firstVisibleViewTag` (NSInteger)                  | N/A                                   |
+| Captured frame        | `_prevFirstVisibleFrame` (CGRect)                   | `prevFirstVisibleFrame` (Rect)        |
+| Config                | `props.maintainVisibleContentPosition`              | `config` (Config object)              |
+| Skip gate             | `_avoidAdjustmentForMaintainVisibleContentPosition` | N/A                                   |
+
+### 6.2 Recomputation Pattern Detail
+
+The recomputation happens at the start of each mount transaction:
+
+```text
+Phase 1: _prepareForMaintainVisibleScrollPosition / willMountItems
+  Purpose: Capture anchor that reflects the current (post-layout, pre-mount) state
+  Executes: Before mount mutations are applied
+  Result: Fresh _firstVisibleView, _firstVisibleViewTag, _prevFirstVisibleFrame
+
+Phase 2: _adjustForMaintainVisibleContentPosition / didMountItems
+  Purpose: Compute and apply scroll correction
+  Step 1: delta = newFrame - prevFirstVisibleFrame
+  Step 2: contentOffset += delta
+  Step 3: (Android only) Update prevFirstVisibleFrame to new frame
+```
+
+### 6.3 JS-Side pendingScrollUpdateCount
+
+The `pendingScrollUpdateCount` field in VirtualizedList state serves dual
+purposes:
+
+1. **Initial scroll index:** Set to `1` when `initialScrollIndex > 0`,
+   preventing render window updates until a valid scroll offset is received from
+   native.
+
+2. **MVCP adjustment tracking:** Incremented when a prepend is detected
+   (JS-side), decremented on each scroll event. While > 0:
+   - `_adjustCellsAroundViewport` returns early (no render window updates)
+   - `_maybeCallOnEdgeReached` is suppressed (edge callbacks don't fire on stale
+     metrics)
+
+This prevents the list from adjusting its render window while native-side MVCP
+corrections are still settling.
+
+---
+
+## 7. Safeguards & Edge Cases
+
+### 7.1 Tag Comparison Safeguard (iOS Fabric)
+
+**Purpose:** Detect when the anchor view was recycled (deleted and recreated
+with a new tag) during mount.
+
+**Implementation:**
+
+```objc
+// Abort if the first visible view has been recycled for a different item.
+// The tag was captured in _prepareForMaintainVisibleScrollPosition (before
+// mounting), and RCTComponentViewRegistry assigns new tags during dequeue
+// (mounting) and resets them to 0 during enqueue (unmounting). When items
+// are removed and re-added, recycled views get new tags based on their
+// position, so the view at position 0 may have a different tag than before.
+// If the tag changed, we bail out to avoid applying the MVCP delta to the
+// wrong view, which would produce incorrect scroll offsets.
+if (_firstVisibleView.tag != _firstVisibleViewTag) {
+    return;  // View was recycled - abort correction
+}
+```
+
+**How it works:**
+
+- `_prepareForMaintainVisibleScrollPosition` captures `_firstVisibleView` and
+  `_firstVisibleViewTag` (the view's React tag)
+- During mount, `RCTComponentViewRegistry` dequeues views from the recycle pool
+  and assigns new tags (`componentViewDescriptor.view.tag = tag`), or resets
+  tags to 0 during enqueue
+- When items are removed and re-added, the same UIView objects may be reused for
+  different items with new tags
+- `_adjustForMaintainVisibleContentPosition` compares the current tag with the
+  captured tag
+- If tags differ → view was recycled → abort correction (avoids applying delta
+  to wrong view)
+
+**Why the check is always active:** `RCTComponentViewRegistry` assigns tags
+during dequeue and resets to 0 during enqueue, regardless of culling state. When
+items are removed and re-added, recycled UIViews get new tags based on their
+position. The view at position 0 may have a different tag than before, so the
+check must always run.
+
+**Impact:** When the anchor view is recycled, MVCP correctly aborts and waits
+for the next batch to recompute from fresh data. Without this check, MVCP would
+apply an incorrect delta to the wrong view, producing incorrect scroll offsets.
+
+### 7.2 Deletion Check (iOS Fabric)
+
+**Purpose:** Detect when the anchor view was deleted (removed from hierarchy)
+during mount, e.g., during `setData([])` + `scrollToOffset(0)` reset.
+
+**Implementation:**
+
+```objc
+if (_firstVisibleView.superview != _contentView) {
+    return;  // View was deleted - abort correction
+}
+```
+
+**When it triggers:**
+
+- `setData([])` clears all items → anchor view removed from `_contentView`
+- `_firstVisibleView.superview` becomes nil
+- `_firstVisibleView.superview != _contentView` → abort
+
+**Why it's needed:** Without this check, MVCP would compute a delta from the
+stale view's frame and apply it to `scrollToOffset(0)`, resulting in incorrect
+offset (e.g., offset ~3876 instead of 0).
+
+**Two abort conditions compared:**
+
+| Scenario             | Tag changed? | Superview changed? | First check (tag) | Second check (superview) |
+| -------------------- | ------------ | ------------------ | ----------------- | ------------------------ |
+| Normal prepend       | No           | No                 | False             | False → **proceed**      |
+| View recycled        | Yes          | No                 | True → **abort**  | -                        |
+| View deleted (reset) | No           | Yes                | False             | True → **abort**         |
+
+Recycling and deletion are mutually exclusive:
+
+- Recycling: view reused for different item → tag changes, superview unchanged
+- Deletion: view removed from hierarchy → tag unchanged, superview becomes nil
+
+### 7.3 Scroll Skip Guards
+
+**Purpose:** Skip MVCP correction during user dragging or momentum scroll to
+avoid conflicting with user gestures.
+
+**Current status:** | Platform | Scroll Skip Guard |
+|----------|------------------| | iOS Fabric | **Not present** in MVCP code.
+`_avoidAdjustmentForMaintainVisibleContentPosition` is driven by a feature flag
+for immediate update mode, not scroll state. | | Android | **Not present**. No
+scroll skip guard in `updateScrollPositionInternal`. |
+
+### 7.4 Divide-by-Zero Guard (JS)
+
+**Location:** `ListMetricsAggregator.js`
+
+```js
+if (this._measuredCellsCount > 0) {
+  this._averageCellLength =
+    this._measuredCellsLength / this._measuredCellsCount;
+}
+```
+
+**Purpose:** Prevents `_averageCellLength` from becoming `Infinity` or `NaN`
+when no cells have been measured yet.
+
+**Related fix:** `_invalidateIfOrientationChanged` clears `_cellMetrics` when
+orientation changes (horizontal/vertical or RTL), preventing stale metrics from
+corrupting new measurements.
+
+### 7.5 Empty List Handling
+
+| Platform   | Behavior                                                                            |
+| ---------- | ----------------------------------------------------------------------------------- |
+| iOS Fabric | Minor bug: nil `.frame` access returns `{0,0}`, causing incorrect scroll correction |
+| Android    | Safe: `firstVisibleViewRef.get() ?: return` early return                            |
+
+### 7.6 Frame Delta Threshold
+
+| Platform   | Threshold          |
+| ---------- | ------------------ |
+| iOS Fabric | `ABS(delta) > 0.5` |
+| Android    | `delta != 0`       |
+
+**Purpose:** Prevents sub-pixel noise from triggering unnecessary scroll
+corrections. The threshold filters out floating-point rounding errors. iOS uses
+0.5px while Android uses exact zero comparison.
+
+### 7.7 Autoscroll to Top Threshold
+
+**Prop:** `autoscrollToTopThreshold` (optional, number)
+
+**Behavior:** When the scroll offset after MVCP correction is within the
+threshold distance from the top (offset < threshold), the list animates to the
+start position. This handles the case where prepending pushes content entirely
+off the top of the screen.
+
+### 7.8 Scroll Event Throttle (Android)
+
+**The throttle mechanism:**
+
+```kotlin
+if (scrollEventType == SCROLL &&
+    scrollView.scrollEventThrottle >= max(17, now - scrollView.lastScrollDispatchTime)) {
+    return  // throttled
+}
+```
+
+**Purpose:** Limits `onScroll` event frequency to reduce JS bridge traffic
+during rapid scrolling. With `scrollEventThrottle = 500`, events are only
+dispatched once per 500ms window.
+
+**Problem:** The throttle blocks MVCP-adjusted scroll events, causing JS state
+to be stale:
+
+- During scroll animation: events are throttled, JS state doesn't update
+- After animation: throttle window hasn't expired, MVCP event is blocked
+- Result: JS offset is stale when MVCP computes delta
+
+**Fix:** Added `emitScrollEventNoThrottle()` that bypasses the throttle check,
+called in two places:
+
+1. **After scroll animations end** (`registerFlingAnimator.onAnimationEnd`):
+   Ensures JS state is updated immediately when animation completes.
+
+2. **After MVCP adjustments** (`MaintainVisibleScrollPositionHelper`): Ensures
+   JS state reflects MVCP-adjusted position immediately.
+
+**Why this is correct:**
+
+- Throttle still applies during active scrolling (reduces traffic as intended)
+- Unthrottled events only fire after animations end or MVCP adjusts position
+- JS state is current when needed for delta calculations
+
+**Platform difference:** iOS uses UIScrollViewDelegate callbacks that don't
+apply the same throttle to programmatic scrolls. Android's ReactScrollView
+applies throttle uniformly to all events.
+
+---
+
+## 8. Design Details and Trade-offs
+
+This section documents specific design choices and the trade-offs that shaped
+the current implementation.
+
+### 8.1 JS Cell Metrics — Orientation Change Handling
+
+The `_cellMetrics` Map stores per-cell layout info keyed by cell ID. When
+orientation changes, the metric coordinate system flips (horizontal ↔ vertical),
+making all stored metrics invalid.
+
+**Why the Map must be cleared (not just counters):** Clearing `_cellMetrics` is
+necessary because the counters alone don't prevent stale entries from being
+found on subsequent `notifyCellLayout` calls. The Map acts as a set of "known
+cells" — if not cleared, old entries persist and interfere with new
+measurements.
+
+**Why the division is guarded:** The `_averageCellLength` computation uses
+`if (count > 0)` rather than relying solely on the orientation change
+invalidation. This is defense-in-depth: even if the invalidation is missed or
+delayed (e.g., rapid orientation changes), the division won't produce `NaN`.
+
+### 8.2 iOS Fabric — Anchor View Abort Conditions
+
+MVCP uses three abort conditions in `_adjustForMaintainVisibleContentPosition`
+to handle views that are no longer valid anchors:
+
+1. **Nil check** (`!_firstVisibleView`): Catches the case where the list was
+   empty during mount and no anchor was captured.
+2. **Tag check** (`_firstVisibleView.tag != _firstVisibleViewTag`): Detects when
+   the anchor view was recycled from the pool and reassigned to a different
+   item. `RCTComponentViewRegistry` assigns tags during dequeue and resets to 0
+   during enqueue, so a tag mismatch means the view no longer represents the
+   same item.
+3. **Superview check** (`_firstVisibleView.superview != _contentView`): Detects
+   when the anchor view was removed from the scroll view's hierarchy (e.g.,
+   during a data reset).
+
+**Ordering rationale:** The nil check is first (cheapest, catches empty list).
+The tag check is second (catches recycling). The superview check is last
+(catches deletion). This ordering minimizes unnecessary checks in the common
+case (normal prepend where all three pass).
+
+**Why the tag check is always active:** `RCTComponentViewRegistry` assigns tags
+during dequeue and resets to 0 during enqueue regardless of culling state. When
+items are removed and re-added (even without culling), recycled UIViews can
+receive new tags based on their new position. The tag check must always run to
+avoid applying a delta to the wrong view.
+
+### 8.3 Android — Scroll Event Throttle Design
+
+`scrollEventThrottle` limits `onScroll` event frequency to reduce JS bridge
+traffic during active scrolling. This creates a trade-off: MVCP adjustments that
+occur during or immediately after a scroll animation may find stale JS offset
+state if the throttle blocks the adjustment event.
+
+**Resolution: selective unthrottling.** The `emitScrollEventNoThrottle()`
+function bypasses the throttle check but is only called in two specific places:
+after scroll animations end, and after MVCP adjustments. This preserves the
+throttle's purpose (reducing JS bridge traffic during active scrolling) while
+ensuring JS state is current when needed for delta calculations.
+
+**Why two call sites are needed:** The animation-end call site ensures JS state
+is updated when a user-initiated scroll animation completes (preventing stale
+state for subsequent MVCP corrections). The MVCP call site ensures JS state
+reflects the MVCP-adjusted position immediately (preventing stale delta
+calculations). Both are needed because MVCP corrections can happen independently
+of scroll animations (e.g., during data updates).
+
+**Platform difference:** iOS uses UIScrollViewDelegate callbacks that don't
+apply the same throttle to programmatic scrolls. Android's ReactScrollView
+applies throttle uniformly to all events, which is why this design detail is
+specific to Android.

+### Interactive REPL
+
+> [!WARNING]
+>
+> The REPL is experimental — its behavior and APIs may change.
+
+You can start an interactive REPL that evaluates JavaScript against the same
+Hermes runtime and React Native environment that Fantom tests use:
+
+```shell
+yarn fantom-cli
+```
+
+Each line is evaluated in a persistent session (bindings declared on one line
+are available on the next) and goes through Metro, so `import`, JSX and Flow
+syntax all work. `React`, `ReactNative` and the `Fantom` API are exposed as
+globals, so you can explore them — and render surfaces — without importing
+anything. Results are printed with a console-style inspector (similar to Chrome
+DevTools / Node.js), and pressing <kbd>Tab</kbd> autocompletes global
+identifiers, in-scope bindings and object properties.
+
+```text
+👻 Fantom REPL — evaluating against Hermes inside the Fantom runtime.
+   ⚠️  Experimental: behavior and APIs may change.
+fantom> const x = 21
+fantom> x * 2
+42
+fantom> ({items: [1, 2, 3], nested: {ok: true}})
+{ items: [ 1, 2, 3 ], nested: { ok: true } }
+```
+
+Press <kbd>Ctrl</kbd>+<kbd>D</kbd> to exit.
+
+Like Node, you can also evaluate a snippet and exit with `-e`, or run a script
+file:
+
+```shell
+yarn fantom-cli -e "console.log(Fantom.getHostPlatform())"
+yarn fantom-cli path/to/script.js
+```
+
+In both cases the value of a trailing expression is not printed (use
+`console.log`), and a thrown error exits with a non-zero status code.
+
+#### Timers and asynchronous code in the REPL
+
+The REPL runs in the Fantom environment, which uses a **deterministic virtual
+clock** — real wall-clock time never passes on its own. A zero-delay
+`setTimeout(fn, 0)` runs right after the current line, but timers with a delay
+(and `setInterval`) stay pending until the clock is advanced, so this does
+**not** print on its own:
+
+```text
+fantom> setTimeout(() => console.log('hi'), 1000)
+```
+
+Drive timers by installing the timer mock and advancing the clock, exactly like
+in a test (see the timers FAQ below):
+
+```text
+fantom> const timers = Fantom.installTimerMock()
+fantom> setTimeout(() => console.log('hi'), 1000)
+fantom> timers.advanceTimersByTime(1000)
+hi
+```
+
 ### Conventions
 
+- Prefer testing React Native through its public API (import from
+  `'react-native'`) whenever possible, rather than reaching into internal
+  modules or relying on private/protected members (e.g. `__`-prefixed methods
+  and fields such as `__getValue()`). Exercising the public API also drives the
+  underlying native (Fabric/TurboModules) code, so tests stay close to real
+  usage and are more resilient to internal refactors. Observe results through
+  the public surface too — e.g. assert the rendered output
+  (`root.getRenderedOutput(...)`) or values delivered to public listeners rather

+#### How can I test logic that relies on timers (`setTimeout`/`setInterval`)?
+
+Fantom runs on a **deterministic virtual clock**: wall-clock time never advances
+on its own, and Fantom decides when the event loop and timers run. In the
+default environment a zero-delay `setTimeout(fn, 0)` is dispatched on the next
+work-loop tick, but timers with a positive delay (and any `setInterval`) stay
+pending and never fire unless the virtual clock is advanced.
+
+To advance the clock and run those callbacks, install a deterministic timer mock
+with `Fantom.installTimerMock()`. While installed, you advance a virtual clock
+to fire them, similar to `jest.useFakeTimers()`:
+
+```javascript
+const timers = Fantom.installTimerMock();
+
+const callback = jest.fn();
+setTimeout(callback, 100);
+
+timers.advanceTimersByTime(50);
+expect(callback).toHaveBeenCalledTimes(0);
+
+timers.advanceTimersByTime(50);
+expect(callback).toHaveBeenCalledTimes(1);
+
+timers.uninstall();
+```
+
+`advanceTimersByTime`/`runAllTimers` run the work loop internally, so callbacks
+have executed by the time they return. Use `getPendingTimerCount()` to inspect
+how many timers are still scheduled, and `uninstall()` (typically in
+`afterEach`) to restore the default behavior.
+

+/**
+ * A deterministic PlatformTimerRegistry for Fantom.
+ *
+ * Unlike the production registry, this implementation does not schedule timers
+ * on a real background thread. Instead it keeps a virtual clock that is only
+ * advanced from JS (through the public Fantom API -> NativeFantom), so that
+ * `setTimeout`/`setInterval` callbacks fire deterministically.
+ *
+ * Two modes:
+ *  - Mock disabled (default): preserves the behavior observable in synchronous
+ *    Fantom tests today. Zero/negative-delay one-shot timers are dispatched
+ *    immediately (they fire on the next work loop); positive-delay and
+ *    recurring timers stay pending and never fire on their own.
+ *  - Mock enabled (via `setMockEnabled(true)`): all timers stay pending and
+ *    only fire when JS advances the virtual clock via `advanceTimersByTime` or
+ *    drains them via `runAllTimers` (jest fake-timer semantics).
+ *
+ * Firing a timer calls `TimerManager::callTimer`, which enqueues the JS
+ * callback on the RuntimeScheduler; the caller is expected to run the work loop
+ * afterwards to execute the callbacks.
+ *
+ * All methods are expected to be called on the JS thread (Fantom is
+ * single-threaded), so no locking is required.
