-description: Use when feature flag tests fail, flags need updating, understanding @gate pragmas, debugging channel-specific test failures, or adding new flags to React.
----
-
-# React Feature Flags
-
-## Flag Files
-
-| File | Purpose |
-|------|---------|
-| `packages/shared/ReactFeatureFlags.js` | Default flags (canary), `__EXPERIMENTAL__` overrides |
-| `packages/shared/forks/ReactFeatureFlags.www.js` | www channel, `__VARIANT__` overrides |
-| `packages/shared/forks/ReactFeatureFlags.native-fb.js` | React Native, `__VARIANT__` overrides |
-| `packages/shared/forks/ReactFeatureFlags.test-renderer.js` | Test renderer |
-
-## Gating Tests
-
-### `@gate` pragma (test-level)
-
-Use when the feature is completely unavailable without the flag:
-
-```javascript
-// @gate enableViewTransition
-it('supports view transitions', () => {
-  // This test only runs when enableViewTransition is true
-  // and is SKIPPED (not failed) when false
-});
-```
-
-### `gate()` inline (assertion-level)
-
-Use when the feature exists but behavior differs based on flag:
-
-```javascript
-it('renders component', async () => {
-  await act(() => root.render(<App />));
-
-  if (gate(flags => flags.enableNewBehavior)) {
-    expect(container.textContent).toBe('new output');
-  } else {
-    expect(container.textContent).toBe('legacy output');
-  }
-});
-```
-
-## Adding a New Flag
-
-1. Add to `ReactFeatureFlags.js` with default value
-2. Add to each fork file (`*.www.js`, `*.native-fb.js`, etc.)
-3. If it should vary in www/RN, set to `__VARIANT__` in the fork file
-4. Gate tests with `@gate flagName` or inline `gate()`
-
-## Checking Flag States
-
-Use `/flags` to view states across channels. See the `flags` skill for full command options.
-
-## `__VARIANT__` Flags (GKs)
-
-Flags set to `__VARIANT__` simulate gatekeepers - tested twice (true and false):
-
-```bash
-/test www <pattern>              # __VARIANT__ = true
-/test www variant false <pattern> # __VARIANT__ = false
-```
-
-## Debugging Channel-Specific Failures
-
-1. Run `/flags --diff <channel1> <channel2>` to compare values
-2. Check `@gate` conditions - test may be gated to specific channels
-3. Run `/test <channel> <pattern>` to isolate the failure
-4. Verify flag exists in all fork files if newly added
-
-## Common Mistakes
-
-- **Forgetting both variants** - Always test `www` AND `www variant false` for `__VARIANT__` flags
-- **Using @gate for behavior differences** - Use inline `gate()` if both paths should run
-- **Missing fork files** - New flags must be added to ALL fork files, not just the main one
-- **Wrong gate syntax** - It's `gate(flags => flags.name)`, not `gate('name')`

-## Instructions
-
-1. Run `yarn prettier` to fix formatting
-2. Run `yarn linc` to check for remaining lint issues

-# Feature Flags
-
-Arguments:
-- $ARGUMENTS: Optional flags
-
-## Options
-
-| Option | Purpose |
-|--------|---------|
-| (none) | Show all flags across all channels |
-| `--diff <ch1> <ch2>` | Compare flags between channels |
-| `--cleanup` | Show flags grouped by cleanup status |
-| `--csv` | Output in CSV format |
-
-## Channels
-
-- `www`, `www-modern` - Meta internal
-- `canary`, `next`, `experimental` - OSS channels
-- `rn`, `rn-fb`, `rn-next` - React Native
-
-## Legend
-
-✅ enabled, ❌ disabled, 🧪 `__VARIANT__`, 📊 profiling-only
-
-## Instructions
-
-1. Run `yarn flags $ARGUMENTS`
-2. Explain the output to the user
-3. For --diff, highlight meaningful differences
-
-## Common Mistakes
-
-- **Forgetting `__VARIANT__` flags** - These are tested both ways in www; check both variants
-- **Comparing wrong channels** - Use `--diff` to see exact differences

-# Flow Type Checking
-
-Arguments:
-- $ARGUMENTS: Renderer to check (default: dom-node)
-
-## Renderers
-
-| Renderer | When to Use |
-|----------|-------------|
-| `dom-node` | Default, recommended for most changes |
-| `dom-browser` | Browser-specific DOM code |
-| `native` | React Native |
-| `fabric` | React Native Fabric |
-
-## Instructions
-
-1. Run `yarn flow $ARGUMENTS` (use `dom-node` if no argument)
-2. Report type errors with file locations
-3. For comprehensive checking (slow), use `yarn flow-ci`
-
-## Common Mistakes
-
-- **Running without a renderer** - Always specify or use default `dom-node`
-- **Ignoring suppressions** - Check if `$FlowFixMe` comments are masking real issues
-- **Missing type imports** - Ensure types are imported from the correct package

----
-name: test
-description: Use when you need to run tests for React core. Supports source, www, stable, and experimental channels.
----
-
-Run tests for the React codebase.
-
-Arguments:
-- $ARGUMENTS: Channel, flags, and test pattern
-
-Usage Examples:
-- `/test ReactFiberHooks` - Run with source channel (default)
-- `/test experimental ReactFiberHooks` - Run with experimental channel
-- `/test www ReactFiberHooks` - Run with www-modern channel
-- `/test www variant false ReactFiberHooks` - Test __VARIANT__=false
-- `/test stable ReactFiberHooks` - Run with stable channel
-- `/test classic ReactFiberHooks` - Run with www-classic channel
-- `/test watch ReactFiberHooks` - Run in watch mode (TDD)
-
-Release Channels:
-- `(default)` - Source/canary channel, uses ReactFeatureFlags.js defaults
-- `experimental` - Source/experimental channel with __EXPERIMENTAL__ flags = true
-- `www` - www-modern channel with __VARIANT__ flags = true
-- `www variant false` - www channel with __VARIANT__ flags = false
-- `stable` - What ships to npm
-- `classic` - Legacy www-classic (rarely needed)
-
-Instructions:
-1. Parse channel from arguments (default: source)
-2. Map to yarn command:
-   - (default) → `yarn test --silent --no-watchman <pattern>`
-   - experimental → `yarn test -r=experimental --silent --no-watchman <pattern>`
-   - stable → `yarn test-stable --silent --no-watchman <pattern>`
-   - classic → `yarn test-classic --silent --no-watchman <pattern>`
-   - www → `yarn test-www --silent --no-watchman <pattern>`
-   - www variant false → `yarn test-www --variant=false --silent --no-watchman <pattern>`
-3. Report test results and any failures
-
-Hard Rules:
-1. **Use --silent to see failures** - This limits the test output to only failures.
-2. **Use --no-watchman** - This is a common failure in sandboxing.
-
-Common Mistakes:
-- **Running without a pattern** - Runs ALL tests, very slow. Always specify a pattern.
-- **Forgetting both www variants** - Test `www` AND `www variant false` for `__VARIANT__` flags.
-- **Test skipped unexpectedly** - Check for `@gate` pragma; see `feature-flags` skill.

-Arguments:
-- $ARGUMENTS: Test pattern for the test step
-
-## Instructions
-
-Run these first in sequence:
-1. Run `yarn prettier` - format code (stop if fails)
-2. Run `yarn linc` - lint changed files (stop if fails)
-
-Then run these with subagents in parallel:
-1. Use `/flow` to type check (stop if fails)
-2. Use `/test` to test changes in source (stop if fails)
-3. Use `/test www` to test changes in www (stop if fails)
-
-If all pass, show success summary. On failure, stop immediately and report the issue with suggested fixes.

-# Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to make participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, sex characteristics, gender identity and expression,
-level of experience, education, socio-economic status, nationality, personal
-appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-  advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies within all project spaces, and it also applies when
-an individual is representing the project or its community in public spaces.
-Examples of representing a project or community include using an official
-project e-mail address, posting via an official social media account, or acting
-as an appointed representative at an online or offline event. Representation of
-a project may be further defined and clarified by project maintainers.
-
-This Code of Conduct also applies outside the project spaces when there is a
-reasonable belief that an individual's behavior may have a negative impact on
-the project or its community.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at <opensource-conduct@fb.com>. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of an incident.
-Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.

 # Contributing to React
 
-Want to contribute to React? There are a few things you need to know.  
+React is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody on [facebook.com](https://www.facebook.com). We're still working out the kinks to make contributing to this project as easy and transparent as possible, but we're not quite there yet. Hopefully this document makes the process for contributing clear and answers some questions that you may have.
 
-We wrote a **[contribution guide](https://reactjs.org/docs/how-to-contribute.html)** to help you get started.
+## [Code of Conduct](https://code.facebook.com/codeofconduct)
+
+Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.
+
+## Our Development Process
+
+Some of the core team will be working directly on GitHub. These changes will be public from the beginning. Other changesets will come via a bridge with Facebook's internal source control. This is a necessity as it allows engineers at Facebook outside of the core team to move fast and contribute from an environment they are comfortable in.
+
+### `master` is unsafe
+
+We will do our best to keep `master` in good shape, with tests passing at all times. But in order to move fast, we will make API changes that your application might not be compatible with. We will do our best to communicate these changes and always version appropriately so you can lock into a specific version if need be.
+
+### Pull Requests
+
+The core team will be monitoring for pull requests. When we get one, we'll run some Facebook-specific integration tests on it first. From here, we'll need to get another person to sign off on the changes and then merge the pull request. For API changes we may need to fix internal uses, which could cause some delay. We'll do our best to provide updates and feedback throughout the process.
+
+*Before* submitting a pull request, please make sure the following is done…
+
+1. Fork the repo and create your branch from `master`.
+2. If you've added code that should be tested, add tests!
+3. If you've changed APIs, update the documentation.
+4. Ensure the test suite passes (`grunt test`).
+5. Make sure your code lints (`grunt lint`) - we've done our best to make sure these rules match our internal linting guidelines.
+6. If you haven't already, complete the CLA.
+
+### Contributor License Agreement (CLA)
+
+In order to accept your pull request, we need you to submit a CLA. You only need to do this once, so if you've done this for another Facebook open source project, you're good to go. If you are submitting a pull request for the first time, just let us know that you have completed the CLA and we can cross-check with your GitHub username.
+
+[Complete your CLA here.](https://code.facebook.com/cla)
+
+## Bugs
+
+### Where to Find Known Issues
+
+We will be using GitHub Issues for our public bugs. We will keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.
+
+### Reporting New Issues
+
+The best way to get your bug fixed is to provide a reduced test case. jsFiddle, jsBin, and other sites provide a way to give live examples. Those are especially helpful though may not work for `JSX`-based code.
+
+### Security Bugs
+
+Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. With that in mind, please do not file public issues; go through the process outlined on that page.
+
+## How to Get in Touch
+
+* IRC - [#reactjs on freenode](https://webchat.freenode.net/?channels=reactjs)
+* Discussion forum - [discuss.reactjs.org](https://discuss.reactjs.org/)
+
+## Style Guide
+
+Our linter will catch most styling issues that may exist in your code.
+You can check the status of your code styling by simply running: `grunt lint`
+
+However, there are still some styles that the linter cannot pick up. If you are unsure about something, looking at [Airbnb's Style Guide](https://github.com/airbnb/javascript) will guide you in the right direction.
+
+### Code Conventions
+
+* Use semicolons `;`
+* Commas last `,`
+* 2 spaces for indentation (no tabs)
+* Prefer `'` over `"`
+* `'use strict';`
+* 80 character line length
+* Write "attractive" code
+* Do not use the optional parameters of `setTimeout` and `setInterval`
+
+### Documentation
+
+* Do not wrap lines at 80 characters

+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are

+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,

+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.
+
+  c. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,

+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws

+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material

+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+

 React is a JavaScript library for building user interfaces.
 
-* **Declarative:** React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
-* **Component-Based:** Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
-* **Learn Once, Write Anywhere:** We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using [Node](https://nodejs.org/en) and power mobile apps using [React Native](https://reactnative.dev/).
+* **Just the UI:** Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
+* **Virtual DOM:** React abstracts away the DOM from you, giving a simpler programming model and better performance. React can also render on the server using Node, and it can power native apps using [React Native](https://facebook.github.io/react-native/).
+* **Data flow:** React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.

+
+### Building Your Copy of React
+
+The process to build `react.js` is built entirely on top of node.js, using many libraries you may already be familiar with.
+
+#### Prerequisites
+
+* You have `node` installed at v0.10.0+ (it might work at lower versions, we just haven't tested) and `npm` at v2.0.0+.
+* You are familiar with `npm` and know whether or not you need to use `sudo` when installing packages globally.
+* You are familiar with `git`.
+
+#### Build
+
+Once you have the repository cloned, building a copy of `react.js` is really easy.
+
+```sh
+# grunt-cli is needed by grunt; you might have this installed already
+npm install -g grunt-cli
+npm install
+grunt build
+```
+
+At this point, you should now have a `build/` directory populated with everything you need to use React. The examples should all work.
+
+### Grunt
+
+We use grunt to automate many tasks. Run `grunt -h` to see a mostly complete listing. The important ones to know:
+
+```sh
+# Build and run tests with PhantomJS
+grunt test
+# Build and run tests in your browser
+grunt test --debug
+# Lint the code with ESLint
+grunt lint
+# Wipe out build directory
+grunt clean
+```

-Execute `yarn snap -d -p <fixture-name>` to compile the fixture with full debug output. This shows the state of the program after each compilation pass. You can also use `yarn snap compile -d <path-to-fixture>`.
-
-### Step 3: Analyze Compilation Results
-
-### Step 3a: If the fixture compiles successfully
-- Compare the output against the user's expected behavior
-- Review each compilation pass output from the `-d` flag
-- Identify the first pass where the output diverges from expected behavior
-- Proceed to binary search simplification
-
-### Step 3b: If the fixture errors
-Execute `yarn snap minimize --update <path-to-fixture>` to remove non-critical aspects of the failing test case. This **updates the fixture in place**.
-
-Re-read the fixture file to see the latest, minimal reproduction of the error.
-
-### Step 4: Iteratively adjust the fixture until it stops erroring
-After the previous step the fixture will have all extraneous aspects removed. Try to make further edits to determine the specific feature that is causing the error.
-
-Ideas:
-* Replace immediately-invoked function expressions with labeled blocks
-* Remove statements
-* Simplify calls (remove arguments, replace the call with its lone argument)
-* Simplify control flow statements by picking a single branch. Try using a labeled block with just the selected block
-* Replace optional member/call expressions with non-optional versions
-* Remove items in array/object expressions
-* Remove properties from member expressions
-
-Try to make the minimal possible edit to get the fixture stop erroring.
-
-### Step 5: Compare Debug Outputs
-With both minimal versions (failing and non-failing):
-- Run `yarn snap -d -p <fixture-name>` on both
-- Compare the debug output pass-by-pass
-- Identify the exact pass where behavior diverges
-- Note specific differences in HIR, effects, or generated code
-
-### Step 6: Investigate Compiler Logic
-- Read the documentation for the problematic pass in `packages/babel-plugin-react-compiler/docs/passes/`
-- Examine the pass implementation in `packages/babel-plugin-react-compiler/src/`
-- Key directories to investigate:
-  - `src/HIR/` - IR definitions and utilities
-  - `src/Inference/` - Effect inference (aliasing, mutation)
-  - `src/Validation/` - Validation passes
-  - `src/Optimization/` - Optimization passes
-  - `src/ReactiveScopes/` - Reactive scope analysis
-- Identify specific code locations that may be handling the pattern incorrectly
-
-## Output Format

-- [additional locations if applicable]
-
-### Suggested Fix Direction
-[Brief suggestion of how the bug might be fixed]
-```
-
-## Key Debugging Tips
-
-1. The debug output (`-d` flag) shows the program state after each pass - use this to pinpoint where things go wrong
-2. Look for `@aliasingEffects=` on FunctionExpressions to understand data flow
-3. Check for `Impure`, `Render`, `Capture` effects on instructions
-4. The pass ordering in `Pipeline.ts` shows when effects are populated vs validated
-5. Todo errors indicate unsupported but known patterns; Invariant errors indicate unexpected states
-
-## Important Reminders
-
-- Always create the fixture file before running tests
-- Use descriptive fixture names that indicate the bug being investigated
-- Keep both failing and non-failing minimal versions for your report
-- Provide specific file:line:column references when identifying suspect code
-- Read the relevant pass documentation before making conclusions about the cause

-# React Compiler Knowledge Base
-
-This document contains knowledge about the React Compiler gathered during development sessions. It serves as a reference for understanding the codebase architecture and key concepts.
-
-## Project Structure
-
-When modifying the compiler, you MUST read the documentation about that pass in `compiler/packages/babel-plugin-react-compiler/docs/passes/` to learn more about the role of that pass within the compiler.
-
-- `packages/babel-plugin-react-compiler/` - Main compiler package
-  - `src/HIR/` - High-level Intermediate Representation types and utilities
-  - `src/Inference/` - Effect inference passes (aliasing, mutation, etc.)
-  - `src/Validation/` - Validation passes that check for errors
-  - `src/Entrypoint/Pipeline.ts` - Main compilation pipeline with pass ordering
-  - `src/__tests__/fixtures/compiler/` - Test fixtures
-    - `error.todo-*.js` - Unsupported feature, correctly throws Todo error (graceful bailout)
-    - `error.bug-*.js` - Known bug, throws wrong error type or incorrect behavior
-    - `*.expect.md` - Expected output for each fixture
-
-## Running Tests
-
-```bash
-# Run all tests
-yarn snap
-
-# Run tests matching a pattern
-# Example: yarn snap -p 'error.*'
-yarn snap -p <pattern>
-
-# Run a single fixture in debug mode. Use the path relative to the __tests__/fixtures/compiler directory
-# For each step of compilation, outputs the step name and state of the compiled program
-# Example: yarn snap -p simple.js -d
-yarn snap -p <file-basename> -d
-
-# Update fixture outputs (also works with -p)
-yarn snap -u
-```
-
-## Compiling Arbitrary Files
-
-Use `yarn snap compile` to compile any file (not just fixtures) with the React Compiler:
-
-```bash
-# Compile a file and see the output
-yarn snap compile <path>
-
-# Compile with debug logging to see the state after each compiler pass
-# This is an alternative to `yarn snap -d -p <pattern>` when you don't have a fixture file yet
-yarn snap compile --debug <path>
-```
-
-## Minimizing Test Cases
-
-Use `yarn snap minimize` to automatically reduce a failing test case to its minimal reproduction:
-
-```bash
-# Minimize a file that causes a compiler error
-yarn snap minimize <path>
-
-# Minimize and update the file in-place with the minimized version
-yarn snap minimize --update <path>
-```
-
-## Version Control
-
-This repository uses Sapling (`sl`) for version control. Sapling is similar to Mercurial: there is not staging area, but new/deleted files must be explicitlyu added/removed.
-
-```bash
-# Check status
-sl status
-
-# Add new files, remove deleted files
-sl addremove
-
-# Commit all changes
-sl commit -m "Your commit message"
-
-# Commit with multi-line message using heredoc
-sl commit -m "$(cat <<'EOF'
-Summary line
-
-Detailed description here
-EOF
-)"
-```
-
-## Key Concepts
-
-### HIR (High-level Intermediate Representation)
-
-The compiler converts source code to HIR for analysis. Key types in `src/HIR/HIR.ts`:
-
-- **HIRFunction** - A function being compiled
-  - `body.blocks` - Map of BasicBlocks
-  - `context` - Captured variables from outer scope
-  - `params` - Function parameters
-  - `returns` - The function's return place
-  - `aliasingEffects` - Effects that describe the function's behavior when called
-
-- **Instruction** - A single operation
-  - `lvalue` - The place being assigned to
-  - `value` - The instruction kind (CallExpression, FunctionExpression, LoadLocal, etc.)
-  - `effects` - Array of AliasingEffects for this instruction
-
-- **Terminal** - Block terminators (return, branch, etc.)
-  - `effects` - Array of AliasingEffects
-
-- **Place** - A reference to a value
-  - `identifier.id` - Unique IdentifierId
-
-- **Phi nodes** - Join points for values from different control flow paths
-  - Located at `block.phis`
-  - `phi.place` - The result place
-  - `phi.operands` - Map of predecessor block to source place
-
-### AliasingEffects System
-
-Effects describe data flow and operations. Defined in `src/Inference/AliasingEffects.ts`:
-
-**Data Flow Effects:**
-- `Impure` - Marks a place as containing an impure value (e.g., Date.now() result, ref.current)
-- `Capture a -> b` - Value from `a` is captured into `b` (mutable capture)
-- `Alias a -> b` - `b` aliases `a`
-- `ImmutableCapture a -> b` - Immutable capture (like Capture but read-only)
-- `Assign a -> b` - Direct assignment
-- `MaybeAlias a -> b` - Possible aliasing
-- `CreateFrom a -> b` - Created from source
-
-**Mutation Effects:**
-- `Mutate value` - Value is mutated
-- `MutateTransitive value` - Value and transitive captures are mutated
-- `MutateConditionally value` - May mutate
-- `MutateTransitiveConditionally value` - May mutate transitively
-
-**Other Effects:**
-- `Render place` - Place is used in render context (JSX props, component return)
-- `Freeze place` - Place is frozen (made immutable)
-- `Create place` - New value created
-- `CreateFunction` - Function expression created, includes `captures` array
-- `Apply` - Function application with receiver, function, args, and result
-
-### Hook Aliasing Signatures
-
-Located in `src/HIR/Globals.ts`, hooks can define custom aliasing signatures to control how data flows through them.
-
-**Structure:**
-```typescript
-aliasing: {
-  receiver: '@receiver',    // The hook function itself
-  params: ['@param0'],      // Named positional parameters
-  rest: '@rest',            // Rest parameters (or null)
-  returns: '@returns',      // Return value
-  temporaries: [],          // Temporary values during execution
-  effects: [                // Array of effects to apply when hook is called
-    {kind: 'Freeze', value: '@param0', reason: ValueReason.HookCaptured},
-    {kind: 'Assign', from: '@param0', into: '@returns'},
-  ],
-}
-```
-
-**Common patterns:**
-
-1. **RenderHookAliasing** (useState, useContext, useMemo, useCallback):
-   - Freezes arguments (`Freeze @rest`)
-   - Marks arguments as render-time (`Render @rest`)
-   - Creates frozen return value
-   - Aliases arguments to return
-
-2. **EffectHookAliasing** (useEffect, useLayoutEffect, useInsertionEffect):
-   - Freezes function and deps
-   - Creates internal effect object
-   - Captures function and deps into effect
-   - Returns undefined
-
-3. **Event handler hooks** (useEffectEvent):
-   - Freezes callback (`Freeze @fn`)
-   - Aliases input to return (`Assign @fn -> @returns`)
-   - NO Render effect (callback not called during render)
-
-**Example: useEffectEvent**
-```typescript
-const UseEffectEventHook = addHook(
-  DEFAULT_SHAPES,
-  {
-    positionalParams: [Effect.Freeze],  // Takes one positional param
-    restParam: null,
-    returnType: {kind: 'Function', ...},
-    calleeEffect: Effect.Read,
-    hookKind: 'useEffectEvent',
-    returnValueKind: ValueKind.Frozen,
-    aliasing: {
-      receiver: '@receiver',
-      params: ['@fn'],              // Name for the callback parameter
-      rest: null,
-      returns: '@returns',
-      temporaries: [],
-      effects: [
-        {kind: 'Freeze', value: '@fn', reason: ValueReason.HookCaptured},
-        {kind: 'Assign', from: '@fn', into: '@returns'},
-        // Note: NO Render effect - callback is not called during render
-      ],
-    },
-  },
-  BuiltInUseEffectEventId,
-);

-// Add as both names for compatibility
-['useEffectEvent', UseEffectEventHook],
-['experimental_useEffectEvent', UseEffectEventHook],
-```
-
-**Key insight:** If a hook is missing an `aliasing` config, it falls back to `DefaultNonmutatingHook` which includes a `Render` effect on all arguments. This can cause false positives for hooks like `useEffectEvent` whose callbacks are not called during render.
-
-## Feature Flags
-
-Feature flags are configured in `src/HIR/Environment.ts`, for example `enableJsxOutlining`. Test fixtures can override the active feature flags used for that fixture via a comment pragma on the first line of the fixture input, for example:
-
-```javascript
-// enableJsxOutlining @enableNameAnonymousFunctions:false
-
-...code...
-```
-
-Would enable the `enableJsxOutlining` feature and disable the `enableNameAnonymousFunctions` feature.
-
-## Debugging Tips
-
-1. Run `yarn snap -p <fixture>` to see full HIR output with effects
-2. Look for `@aliasingEffects=` on FunctionExpressions
-3. Look for `Impure`, `Render`, `Capture` effects on instructions
-4. Check the pass ordering in Pipeline.ts to understand when effects are populated vs validated
-
-## Error Handling for Unsupported Features
-
-When the compiler encounters an unsupported but known pattern, use `CompilerError.throwTodo()` instead of `CompilerError.invariant()`. Todo errors cause graceful bailouts in production; Invariant errors are hard failures indicating unexpected/invalid states.
-
-```typescript
-// Unsupported but expected pattern - graceful bailout
-CompilerError.throwTodo({
-  reason: `Support [description of unsupported feature]`,
-  loc: terminal.loc,
-});
-
-// Invariant is for truly unexpected/invalid states - hard failure
-CompilerError.invariant(false, {
-  reason: `Unexpected [thing]`,
-  loc: terminal.loc,
-});
-```

-# React Compiler
-
-React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
-
-More information about the design and architecture of the compiler are covered in the [Design Goals](./docs/DESIGN_GOALS.md).
-
-More information about developing the compiler itself is covered in the [Development Guide](./docs/DEVELOPMENT_GUIDE.md).

-# React Compiler Playground
-
-An interactive playground to demonstrate, test, and have fun with React Compiler.
-
-## Setup
-
-```sh
-# Build React Compiler from source and install Playground dependencies.
-$ yarn
-
-# Or similarly
-$ npm install
-```
-
-## Development
-
-```sh
-# Start the local development server with
-$ yarn dev
-
-# Or
-$ npm run dev
-
-# Rerun the following (in a separate terminal window) when React Compiler
-# is changed locally to keep Playground in sync.
-$ yarn
-```
-
-## Testing
-```sh
-# Install playwright browser binaries
-$ npx playwright install --with-deps
-# Run tests
-$ yarn test
-```
-## Deployment
-
-This project has been deployed using Vercel. Vercel does the exact same thing as we would
-locally, by running `yarn` at the install step in the Playground directory to build
-React Compiler from source and [symlink](https://classic.yarnpkg.com/en/docs/cli/link) it as its dependency.
-This means that Playground is automatically deployed on every push and pull requests will reflect
-the behaviors of React Compiler of that commit.
