How it works

Methodology

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.

Relationship to Growth / Maintenance / Fixes

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.

Proposed API Endpoint

Currently computed client-side from commit and bug attribution data. Ideal server-side endpoint:

POST /v1/organizations/{orgId}/investment-quality
Content-Type: application/json

Request:

  "endTime": "2025-12-31T23:59:59Z",
  "bucketSize": "BUCKET_SIZE_MONTH",
  "groupBy": ["repository_id" | "deliverer_email"]

a19d6a6This commit provides a **bug fix** for the **membership verification logic** within the **GitHub Actions workflows** `bonk-pr-review.yml` and `bonk.yml`. It addresses an issue where these workflows incorrectly relied on `author_association` for determining Cloudflare organization membership. The change involves **removing the unreliable `author_association` condition** and introducing a new, explicit step to verify Cloudflare organization membership for both PR authors and comment authors. This ensures that the "bonk" functionality correctly identifies internal contributors, improving the reliability of **automated workflow execution** and preventing erroneous behavior.Mar 202waste
3a1c149This commit introduces **full R2 support** to the **local explorer UI** and its underlying `miniflare` backend, providing a **new capability** for developers to manage Cloudflare R2 buckets and objects directly within their local development environment. The `local-explorer-ui` now features dedicated routes, components for object listing (`R2ObjectTable`) and uploading (`R2UploadDialog`), and sidebar navigation for R2 resources. Concurrently, `miniflare` integrates R2 API endpoints (list, get, put, delete) and resource handlers, along with updated OpenAPI definitions. This significantly enhances the developer experience by allowing visual interaction with R2 storage, complete with comprehensive testing and fixture updates for R2 functionality.Mar 1934grow
ce48b77This commit **enables the local explorer feature by default** within the `wrangler dev` environment, removing the need for users to explicitly set an environment variable. Specifically, it modifies `packages/workers-utils` to change the default value of `X_LOCAL_EXPLORER` from `false` to `true`. The `packages/wrangler` hotkey logic is updated to reflect this always-on state, and several **test suites** in `fixtures/interactive-dev-tests` and `fixtures/worker-with-resources` are **refactored** to remove the now-redundant `X_LOCAL_EXPLORER=true` condition. This **feature enablement** streamlines the developer experience by making the local explorer readily accessible without additional configuration.Mar 185grow
ade0aedThis commit implements a **critical security fix** for the **Miniflare local explorer**, specifically addressing **host and origin header validation**. It introduces new functions like `validateLocalExplorerRequest` and `isHostnameAllowed` within `packages/miniflare/src/workers/core/entry.worker.ts` to ensure these security checks are performed *before* any header rewriting. This **refactoring** relocates and enhances validation logic from `explorer.worker.ts` to the core entry point, preventing potential header spoofing or unauthorized access to the local explorer API. The **bug fix** significantly improves the **security and robustness** of the local development environment. Comprehensive new test cases were added to verify correct behavior across various host/routing configurations and subdomain blocking.Mar 135waste
85f38a0This commit **refactors** the **`local-explorer-ui`** package by **migrating its user interface components from the deprecated `@base-ui` library to the modern `@cloudflare/kumo` design system**. This involved updating numerous components such as `Button`, `Breadcrumbs`, `Menu`, and `Table` within files like `AddKVForm.tsx`, `KVTable.tsx`, and various route definitions. The change ensures the **Local Explorer UI** now leverages the latest Kumo components, improving consistency, maintainability, and aligning with current design standards. Additionally, the `TableSelect` component was extracted into a shared module for enhanced reusability across routes.Mar 1316maint
a25101bThis commit **quarantines the end-to-end tests** for the **SolidJS framework** within the `create-cloudflare` project. It performs **test management** by modifying the `packages/create-cloudflare/e2e/tests/frameworks/test-config.ts` file to set `quarantine: true` for Solid's configuration in both `getFrameworkTestConfig` and `getExperimentalFrameworkTestConfig`. This **maintenance** change effectively **disables the execution of SolidJS E2E tests**, preventing them from running in standard and experimental test suites. The immediate impact is that these tests will no longer block CI/CD pipelines, allowing for further investigation or fixes to the SolidJS integration.Mar 101maint
e4d9510This commit introduces **cross-process support** to the **Miniflare local explorer**, a significant **new capability** that allows it to aggregate and display resources from multiple concurrently running Miniflare instances. It enables a unified view of **KV, D1, and Durable Object resources** across different workers, greatly enhancing the developer experience for multi-worker projects. The implementation involves adding a new `/core/dev-registry` endpoint for instance discovery, developing core aggregation logic in `packages/miniflare/src/workers/local-explorer/aggregation.ts`, and updating resource drivers (`d1.ts`, `do.ts`, `kv.ts`) to proxy and aggregate data. Additionally, it includes **refactoring** of D1 API calls, updating OpenAPI specifications to remove pagination, and adding comprehensive **new tests** to validate the cross-process functionality. This ensures that all simulated Cloudflare resources are discoverable and manageable from a single explorer interface, regardless of which Miniflare process they belong to.Mar 933grow
a7c87d1This commit introduces **CORS and host header validation** to the **Miniflare local explorer API**, enhancing its security posture. It implements new middleware within `explorer.worker.ts` to restrict incoming requests, ensuring that only local origins are permitted and properly handling CORS preflight requests. This **new security feature** prevents unauthorized external access and mitigates potential DNS rebinding attacks, thereby safeguarding the local development environment. Comprehensive test cases have been added to verify the correct behavior, including local origin allowance, external origin blocking, and proper preflight response handling.Mar 93grow
4bdb35eThis commit introduces a **new automated code reviewer** named 'bonk' to the project, representing a **new capability** for code quality assurance. It adds new **GitHub Actions workflows** (`bonk-pr-review.yml`, `bonk.yml`) to automatically trigger 'bonk' for pull request reviews upon opening, and also via issue or pull request review comments. Additionally, documentation for the 'bonk' reviewer, outlining its restrictions and output rules, is included in `.github/bonk_reviewer.md`. This integration significantly enhances the project's **CI/CD and automated review processes** by providing an additional layer of automated feedback.Mar 93grow
