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.

| 0423c43b | Affects the internal GitHub Actions workflow responsible for dependency updates; this is an operational adjustment to align with team schedules and has no direct production impact. | Mar 4 | 1 | maint |
| 1052d2e4 | This is an isolated documentation change, renaming a markdown file from `CLAUDE.md` to `AGENTS.md`. It has no impact on production systems or functionality. | Feb 23 | 1 | maint |
| fe9c1a67 | Affects the CI/CD pipeline; ensures Web Platform Tests consistently generate reports for pull requests by standardizing the build configuration, improving test visibility for developers. | Feb 23 | 3 | maint |
| adcc7622 | This change introduces ZSTD compression support to the `node:zlib` package, providing a new capability for applications to utilize ZSTD for improved data compression and decompression. | Feb 19 | 14 | grow |
| 4a315ee9 | Attempt to hold back capnproto | Feb 13 | 2 | – |
| f467c699 | This commit primarily affects internal dependency management for `wpt` and `ada-url` within the project, making them shared dependencies. It includes an update to the `url-test.ts` file, indicating an isolated change to internal test infrastructure for URL parsing. | Jan 30 | 5 | maint |
| 637f37fa | This commit modifies the Codecov integration configuration. It refines the CI/CD feedback by ensuring Codecov comments are only posted on pull requests when code coverage drops, reducing noise in PR discussions. | Jan 28 | 1 | maint |
| a8a90d4d | This change enhances the Bazel dependency management system by allowing `bazel_dep` modules to be combined with `archive` or `git_override` mechanisms. This introduces a new capability for more flexible and robust external dependency resolution within `MODULE.bazel` files. | Jan 20 | 8 | grow |
| b24baa9a | This commit fixes a build configuration issue within the `workerd` API tests, addressing a network dependency for a specific test. This is an isolated change to the testing infrastructure with no production impact. | Jan 14 | 1 | waste |
| d3f6908a | This change significantly alters the test environment by blocking network access for most Bazel-managed tests by default. This aims to improve test isolation and reliability, potentially exposing implicit network dependencies in existing tests. | Jan 14 | 2 | maint |
| 9455e957 | This commit significantly overhauls the Bazel dependency management system, automating `bazel_dep` updates and consolidating declarations within `MODULE.bazel`. It streamlines the build process's handling of external dependencies, impacting all future builds. | Jan 13 | 41 | maint |
| a301bb4e | This commit fixes a permission issue and updates runner resources for the manual Web Platform Tests (WPT) reporting workflow in GitHub Actions. It's an isolated change to CI/CD infrastructure, improving the reliability and performance of this specific testing process. | Jan 7 | 1 | waste |
| 32d43a0f | This is an isolated fix to the WPT statistics generation tool (`wpt_logs.py`). It refines the data included in WPT stats by excluding specific variants, improving the accuracy and relevance of reported test results. | Jan 7 | 1 | waste |
| 2fbab142 | This commit initiates a significant migration of the project's dependency management from the traditional WORKSPACE model to Bazel's bzlmod system. This infrastructure change affects how all external dependencies are resolved and managed, impacting the build process and requiring updates to the `update-deps.py` script. | Dec 18 | 61 | grow |
| 93328f5c | This commit refactors the internal dependency generation scripts (`update-deps.py`) and the structure of the generated dependency files. It is an isolated, non-functional change to the build system's maintenance, with no impact on product functionality or external dependencies. | Dec 11 | 42 | – |
| 7b106e2d | This commit introduces a new developer utility (`just new-test`) for creating test stubs, affecting developer workflow and tooling. It's an isolated change with no direct impact on production systems or existing features. | Dec 3 | 2 | grow |
| af09aa71 | This commit standardizes the internal structure and build configuration of the `workerd` API test suite. It is an isolated refactoring effort with no impact on production code or external functionality. | Dec 2 | 49 | maint |
| 1866aa44 | This commit reverts a previous change, removing job timeouts from all Github Actions CI/CD workflows. This means CI jobs will no longer be automatically terminated after a set duration, potentially allowing long-running or stuck jobs to consume more resources. | Nov 18 | 4 | maint |
| 7a125e87 | This commit updates GitHub Actions CI/CD workflows to include job timeouts, improving the reliability and efficiency of the build and test process. It ensures that CI jobs do not run indefinitely, providing faster feedback to developers. | Nov 14 | 4 | maint |
| 50ce1b10 | This change updates the internal build system's management of the `codespan-reporting` Rust dependency. It's an isolated refactor of dependency definitions with no direct impact on production features or user-facing functionality. | Nov 11 | 5 | maint |
