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.

| a2fa4ea3 | This commit delivers a **fix** for the **chat rename and usages tools**, specifically addressing their registration and user interface presentation. It ensures that these tools, part of the **`chat` workbench contribution**, will now skip registration if no relevant language providers are available, preventing unnecessary tool activation and improving stability. Furthermore, the update enhances the user experience by displaying **language names in the UI** when these tools are active, providing clearer context for code-related operations within the chat interface. This is a **bug fix** and **usability improvement** that also includes updated tests for the new `ILanguageService` dependency and `getToolData` behavior. | Mar 20 | 4 | – |
| d05f2f29 | This commit introduces a **new capability** for the **inline chat feature** by implementing a shared `InlineChatHistoryService`. This service is responsible for managing and **persisting inline chat history**, allowing users to recall previous inputs across sessions. The `inlineChatOverlayWidget` has been **refactored** to utilize this new service, replacing its internal history management with the centralized, persistent solution. This significantly enhances the user experience by providing reliable and persistent history navigation within the inline chat input. | Mar 20 | 3 | grow |
| f0a991b7 | This commit introduces a **stepped resize mechanism** for the **inline chat input widget's width**, enhancing its responsiveness and visual consistency. This **feature enhancement** specifically impacts the **inline chat** UI, where the input field within the `inlineChatOverlayWidget.ts` now adjusts its size in discrete steps. The change ensures a more controlled and predictable resizing behavior for the input area, improving the overall user experience within the inline chat interface. | Mar 20 | 1 | – |
| dd7c043b | This commit introduces a **new feature** by adding the `chat.editing.revealNextChangeOnResolve` setting, allowing users to control the **auto-jump behavior** within the **Chat editing experience**. Specifically, it enables users to decide if the editor should automatically reveal the next suggested change after they resolve a current one (by keeping or undoing it). This **enhancement** modifies the core auto-jump logic in `chatEditingEditorActions.ts` to respect the new setting, providing greater personalization and improving the workflow for interacting with AI-generated content. | Mar 20 | 3 | – |

| 81a1a5ff | This commit **enhances quick input context handling** by introducing a new **"attach" functionality** for active quick pick items. It extends the **Quick Input API** with `onDidAttach` and an `attach` method, allowing quick pick items to define and respond to an "attach" action. This **new capability** is integrated into `pickerQuickAccess.ts` and specifically refined for `gotoSymbolQuickAccess.ts`, enabling actions like revealing a symbol without closing the picker. Furthermore, a **new keybinding** (Shift+Enter / Cmd+DownArrow) is registered to explicitly trigger this attach action, providing users with more control over quick input interactions. | Mar 20 | 8 | grow |
| 38294990 | This commit introduces a **new capability** to the **Go to Symbol Quick Access** feature by adding an optional `attach` method to the `IGotoSymbolQuickPickItem` interface. This **enhancement to symbol handling** allows for custom logic or data to be associated with symbol quick pick items, providing greater flexibility for future interactions. The `getPicks` method within the **workbench's code editor contribution** (`src/vs/workbench/contrib/codeEditor/browser/quickaccess/gotoSymbolQuickAccess.ts`) is updated to assign this `attach` method, ensuring it's available for use. This change primarily affects the **editor and workbench contributions** related to symbol navigation, enabling more dynamic and context-aware behavior when selecting symbols. | Mar 20 | 2 | grow |
