Breakdown of growth, maintenance, and fixes effort over time.
Bugs introduced vs. fixed over time.
Reclassifies engineering effort based on bug attribution. Commits that introduced bugs are retrospectively counted as poor investments.
Investment Quality reclassifies engineering effort based on bug attribution data. Commits identified as buggy origins (those that introduced bugs later fixed by someone) have their grow and maintenance time moved into the Wasted Time category. Their waste (fix commits) remains counted as productive. All other commits retain their standard classification: grow is productive, maintenance is maintenance, and waste (fixes) is productive.
The standard model classifies commits as Growth, Maintenance, or Fixes. Investment Quality adds a quality lens: a commit that introduced a bug is retrospectively counted as a poor investment — the engineering time spent on it was wasted because it ultimately required additional fix work. Fix commits (Fixes in the standard model) are reframed as productive, because fixing bugs is valuable work.

It **refactors** the previous blind application of development headers by allowing developers to register a custom provider block via `RCTSetCustomSRWebSocketProvider`. This **new capability** provides greater control over WebSocket creation, allowing for use cases like injecting authentication headers for specific endpoints. The `RCTWebSocketModule.h` and `RCTWebSocketModule.mm` files are updated to declare and implement this provider hook, ensuring that if no provider is set or returns nil, the default `SRWebSocket` creation logic is used. | Mar 4 | 2 | grow |
| 0c7d780 | This commit introduces a **new capability** for **HTTP networking** by adding an `RCTHTTPRequestInterceptor` to the `RCTHTTPRequestHandler` module. It **refactors** the previous blind application of development headers, allowing developers to register a custom block via `RCTSetCustomHTTPRequestInterceptor` to inspect and **selectively modify outgoing HTTP requests**. This provides granular control over header injection, enabling per-request customization while preserving the shared `NSURLSession` configuration. The change enhances flexibility for **network request customization** within the framework. | Mar 4 | 2 | grow |
| ca41737 | This commit **enhances** the **React DevTools connection mechanism** by dynamically deriving the WebSocket scheme (ws/wss) and port directly from the development server's URL. This **new capability**, implemented in `setUpReactDevTools.js`, ensures that **React DevTools connections function correctly when the development server is accessed over HTTPS**. It specifically addresses the challenge of connecting to secure dev servers, providing a robust solution that also includes a fallback for standard local development environments. This **maintenance** work improves the developer experience by enabling seamless DevTools integration across various server configurations. | Mar 4 | 1 | grow |
| 36dfcef | This commit **enhances the iOS development experience** by dynamically deriving the URL scheme for the **inspector and debugger functionality**. Previously, the `RCTInspectorDevServerHelper` module hardcoded `http://` when constructing device and debugger URLs, preventing these tools from connecting when the development server was accessed over HTTPS. This **new capability** now ensures that functions like `getInspectorDeviceUrl` correctly use the bundle URL's scheme, **enabling seamless debugging and inspection** for React Native iOS applications served over secure connections. | Mar 4 | 1 | grow |
| 3582a8b | This commit **fixes a bug** in the **iOS inspector's development server helper** (`RCTInspectorDevServerHelper`) by updating the `getServerHost()` function. It now correctly determines the server host and port, especially when dealing with **HTTPS bundle URLs**. The change ensures that the explicit port from the URL takes priority, followed by the `RCT_METRO_PORT` environment variable, and correctly omits the default port for HTTPS schemes. This **bug fix** improves the reliability of the **iOS inspector's** connection to the Metro development server when using secure connections. | Mar 4 | 1 | waste |
| 9bc7d38 | This commit **fixes a critical bug** in the **iOS build process** where `tar` extraction within the `replace-rncore-version.js` script would silently fail on **EdenFS**. Previously, this led to incomplete `React-Core-prebuilt` installations, causing subsequent builds to use an incorrect or partial configuration. The **bug fix** now extracts tarballs to a temporary directory, verifies the extraction's success (including checking tar's exit code), and then moves the contents to the final location. This ensures all necessary files are present in `React-Core-prebuilt`, preventing silent build failures and guaranteeing reliable **iOS builds** for developers working on **EdenFS**. | Mar 3 | 1 | waste |
| aefe0f5 | This commit introduces a **workflow improvement** to the **CI/CD pipeline**, specifically within the **Android build process**. It **modifies the condition** for executing the `set-rn-artifacts-version.js` script in `.github/actions/build-android/action.yml`. Previously, this script would incorrectly run for Pull Requests targeting stable branches; now, it will **skip execution** in such scenarios by checking the `github.base_ref`. This change prevents unnecessary processing and **improves CI efficiency** by ensuring the versioning script only runs when relevant. | Mar 2 | 1 | waste |
| bc8e71c | This commit provides a **bug fix** for **multi-architecture Apple builds**, specifically addressing an issue where `clang`'s `-target` and `-arch` flags were incorrectly combined, resulting in an improper target triple. It modifies the `configure_apple_framework` function within the `utils/build-apple-framework.sh` script. The change ensures that a single `-target` flag is used, allowing CMake to correctly manage multi-arch `-arch` flags. This guarantees that **Hermes binaries are properly structured** and include all necessary architectures for Apple platforms, particularly for Catalyst builds. | Jan 28 | 2 | waste |
| 4fb3302 | This commit **updates** the **Hermes JavaScript engine version** integrated into **React Native** to `250829098.0.6`.

This **maintenance update** ensures that **React Native projects** consume the latest stable Hermes V1 release, aligning the framework with recent engine developments. | Jan 15 | 1 | maint |
| 7ed7540 | This commit **updates the E2E test configuration** to utilize **prebuilt React Native artifacts** for the template app, aligning the testing environment with the default release process. It enables the `RCT_TESTONLY_RNCORE_TARBALL_PATH` environment variable within the `.github/workflows/test-all.yml` CI workflow. This **maintenance change** ensures that end-to-end tests accurately reflect the behavior of production builds, improving test reliability and consistency. The scope is limited to the **testing infrastructure**, specifically how React Native is sourced for E2E runs. | Jan 14 | 1 | maint |
| 5333759 | This commit performs **maintenance** on the project's **CI/CD workflows** by **bumping the default Xcode version to 16.4.0** within the `.github/actions/setup-xcode` GitHub Action. Crucially, it **removes the capability and logic for explicitly downloading Apple SDKs**, streamlining the setup process and potentially **reducing CI build times and costs**. The `.github/actions/test-ios-rntester` action is also updated to align with these changes, no longer specifying platform SDKs and defaulting unit tests to `false`. This **optimization** simplifies the Xcode environment setup in CI by assuming necessary SDKs are pre-installed or handled differently. | Jan 14 | 8 | maint |
| f140c49 | This commit **makes Hermes V1 the default JavaScript engine** for React Native applications across **both iOS and Android platforms**. It involves **updating the build system configuration**, including the `gradle.properties` file, the `react-native-gradle-plugin`, and **iOS Pods integration** to enable Hermes V1 by default. This **significant configuration change** ensures that new projects and those not explicitly overriding the engine will benefit from Hermes V1's performance improvements and smaller bundle sizes. The change also updates **prebuild scripts and CI workflows** to reflect this new default, serving as a **critical preparatory step** for the upcoming `react-native 0.84` release. | Jan 7 | 14 | grow |
| dcfe7f5 | This commit **updates the Android build CI/CD pipeline** by modifying the `.github/actions/build-android/action.yml` workflow. It introduces a new step to read the current React Native version and adjusts the condition for setting the RN version to include stable branches. This **maintenance change** ensures that **release candidate versions (RC.0)** are correctly processed by the build system, particularly when the development version is `1000.0.0`. The update facilitates proper testing and release of new React Native versions by correctly identifying and handling these specific versioning scenarios within the **CI environment**. | Jan 6 | 1 | maint |
| 7e4fa70 | This commit introduces a **CI/CD improvement** by configuring the GitHub Actions workflow to automatically **rerun failed Fantom tests**. Specifically, the `.github/workflows/test-all.yml` file is updated to include `run_fantom_tests` in the `rerun-failed-jobs` workflow's dependencies and conditions. This **maintenance** change addresses the known flakiness of the **Fantom test suite**, ensuring more reliable and accurate test results without manual intervention. The primary impact is a reduction in false-negative test failures, streamlining the development and release process by mitigating intermittent test failures. | Jan 6 | 1 | maint |
| a425f4f | This commit provides a **bug fix** for the **`validate-dotslash-artifacts` GitHub Actions workflow**, addressing a recurring CI failure caused by an incompatible Node.js version. Previously, the job would fail due to requiring Node.js `>= 22.11.0` but running on `20.19.6`. The change explicitly adds a step within `.github/workflows/validate-dotslash-artifacts.yml` to set up the correct Node.js environment, ensuring the **CI pipeline** runs reliably. This **maintenance** prevents false negatives and improves the stability of automated artifact validation. | Jan 6 | 1 | waste |
