Breakdown of growth, maintenance, and fixes effort over time.
Bugs introduced vs. fixed over time.
No bugs introduced or fixed in this period.
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.

| a09e565c | This commit **implements per-actor SQLite memory metering** within the `workerd` runtime, a **new capability** designed to track resource consumption more precisely. It introduces a **custom SQLite memory allocator** and `SqliteMemoryScope` to accurately measure memory usage for each `SqliteDatabase` instance. The core `SqliteDatabase` utility class is updated to integrate this metering, and the `LimitEnforcer` interface in the **`workerd` runtime** is extended to expose the new `getSqliteMemoryUsage` metric. This foundational change enables granular resource governance, allowing the system to monitor and potentially enforce memory limits on individual SQLite databases used by actors, thereby improving stability and resource isolation. | Mar 22 | 12 | grow |

| 7825defd | Affects the `HibernationManager` in `workerd`; this is a logging refinement that reduces noise by only logging internal exceptions, improving observability without changing core functionality. | Mar 2 | 1 | waste |
| 7d314b1b | This update affects the `create-cloudflare` (C3) templates for Durable Objects, ensuring all newly generated projects use the `getByName` method for Durable Object instantiation. This is an isolated change to project scaffolding, with no impact on existing deployed applications. | Aug 21 | 7 | maint |
| b2053584 | This commit introduces a **documentation update** by adding a new entry to the **Durable Objects release notes** in `src/content/release-notes/durable-objects.yaml`. It specifically details the **new API capability** allowing developers to construct Durable Object stubs by name using the `getByName()` method. This **maintenance task** ensures users are informed about the latest features, enhancing their ability to programmatically interact with Durable Objects. | Aug 21 | 1 | maint |
| b4d58dd2 | This commit **updates documentation** across various sections, primarily within the **Durable Objects** guides and examples. It standardizes the recommended approach for creating Durable Object stubs by replacing the `idFromName` and `get` method calls with the more direct and preferred `getByName` method. This **documentation update** ensures developers are guided towards the most efficient and current API usage, improving clarity and consistency in code examples throughout the documentation. The changes affect numerous tutorials, best practices, and API reference pages related to Durable Objects, as well as examples in Workers, Queues, and AI documentation. | Aug 21 | 27 | maint |

| 0e8a33dc | This change introduces a new `getJurisdiction` method to `DurableObjectId` within the `workerd` runtime, providing a new API capability for Durable Objects. This will allow developers to retrieve jurisdiction information directly from Durable Object IDs, affecting all services that interact with Durable Objects. | Aug 14 | 8 | grow |
| a1a73f2a | Merge pull request #4779 from cloudflare/joshthoward/fix-getByName | Aug 14 | 0 | – |
| 8cadf693 | This change impacts the TypeScript type generation for the `workerd` runtime's `actor` API. It's an internal tooling improvement to ensure correct type overrides for the `getByName` function, with no direct impact on runtime behavior or end-user functionality. | Aug 14 | 5 | grow |
| 7e5d6c77 | This change affects the `workerd` actor API, introducing a new capability by allowing the `jurisdictions` field to be null. This provides greater flexibility in actor configuration and may simplify use cases where jurisdiction is not always required. | Aug 13 | 3 | grow |

| 30597771 | This change enhances the `workerd` actor management system by allowing jurisdictions to be undefined. This provides new flexibility in how actors are identified and managed within the `workerd` runtime. | Aug 12 | 5 | grow |

| f8649ab7 | This commit introduces a new `getByName` method to the `DurableObjectNamespace` API, providing a new capability for developers to retrieve Durable Objects by name within the Workerd environment. This expands the API surface for Durable Objects. | Aug 8 | 7 | grow |

| a70a30e5 | This is an isolated refactoring within the `workerd/api/actor` module, moving class definitions to a header file. It has no functional impact on external behavior or APIs. | Aug 7 | 2 | maint |
| c93cc26e | This commit provides a **documentation update** to the **Durable Objects pricing guide**, specifically clarifying how duration is billed. It **removes a misleading sentence** regarding request context extension and adjusts table and footnote formatting within `durable-objects-pricing.mdx`. This ensures users have an accurate understanding of **Durable Objects** billing, emphasizing that charges do not extend beyond the last request. The change improves the clarity and accuracy of critical pricing information for developers. | Jun 24 | 1 | maint |
| 7eef055d | This commit **fixes a critical issue in the Durable Objects TTL example documentation** by preventing infinite alarm invocations. Specifically, it **removes the `setAlarm` call from the constructor** within the `src/content/docs/durable-objects/examples/durable-object-ttl.mdx` example. This **documentation fix** addresses a scenario where long Time-To-Live values could inadvertently trigger continuous alarms, improving the reliability and correctness of the provided code example. Users following this documentation will now be guided towards a safer and more efficient implementation of **Durable Objects** with alarms, avoiding potential resource exhaustion. | May 29 | 1 | – |
