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.

The scope is limited to the visual styling of this specific UI element within the sessions module. | Mar 30 | 1 | maint |
| 3d3ff03a | This commit introduces **maintenance and styling updates** to the **sessions changes view**, specifically enhancing its integration with the modal editor. It **refactors** the file opening logic within `src/vs/sessions/contrib/changes/browser/changesView.ts` by dynamically adjusting the `openFileItem` function's last parameter based on the number of items, improving how files are handled. Concurrently, the commit **updates CSS selectors** in `src/vs/sessions/contrib/changes/browser/media/changesView.css` from `.changes-view-body` to `.chat-editing-session-list`, ensuring the visual presentation of the changes view aligns with new styling for the **chat editing session list**. This work ensures the **changes view** functions and appears correctly within the updated UI context. | Mar 30 | 2 | maint |
| 33741c26 | This commit **fixes a performance bug** by addressing **CPU stalls** caused by pathological regular expressions in the default `files.watcherExclude` patterns. It **modifies the default patterns** within the **files workbench contribution** (`src/vs/workbench/contrib/files/browser/files.contribution.ts`) to use less complex regex. This **bug fix** prevents resource exhaustion and significantly improves performance, especially when working with **large repositories** where file watching is critical. | Mar 30 | 2 | waste |
| 2e202521 | This commit provides a **bug fix** for the **sessions UI component**, resolving an issue where the **session item height** in the tree view was incorrectly rendered. The problem stemmed from an undefined value being used for height calculation, particularly noticeable when approving sessions. This fix ensures the `sessionsList.ts` correctly leverages the delegate's height calculation, preventing UI glitches and improving the visual stability of the **sessions feature**. Users will now experience a more consistent and accurate display of session items within the session list. | Mar 29 | 1 | waste |
| 9a6bf81d | This commit performs a significant **cleanup and refactoring** of the **modal editor sidebar** implementation, addressing technical debt related to its initial support. It primarily **removes redundant `minWidth` properties and associated layout logic** from `IModalEditorPartOptions` and `ModalEditorPart`, simplifying how the modal editor handles its sidebar's dimensions and event handling. Additionally, the `changesView` is refactored to improve its integration with the modal editor sidebar, including updates to tree creation and file opening logic. This **maintenance** work enhances code clarity and maintainability within the **workbench editor parts** and **platform editor definitions**, ensuring a more streamlined and robust foundation for modal editor experiences, as validated by new dedicated tests for the modal editor sidebar. | Mar 29 | 8 | maint |
| 1bff585f | This commit delivers a **bug fix** addressing a **regression** related to **quick input positioning**. It updates the type definitions for `anchor` and `widget` properties within the **Quick Input API** (`IPickOptions`, `IQuickInput`, `IQuickWidget`) to `unknown /* HTMLElement */` in `src/vs/platform/quickinput/common/quickInput.ts`. Additionally, `src/vs/platform/quickinput/browser/quickInputController.ts` now includes a type assertion for `getAnchorRect` to correctly handle anchor types, ensuring the quick input widget is reliably positioned relative to its DOM anchor. This resolves issues where quick inputs might have been incorrectly positioned due to type mismatches. | Mar 29 | 4 | waste |
| 18675700 | This commit introduces **sidebar support for modal editors**, enabling a new UI area for contextual information within these temporary editor instances. It primarily affects the **workbench's modal editor part** (`modalEditorPart.ts`) by implementing the creation, resizing, and content management of this new sidebar, along with necessary styling adjustments in `modalEditorPart.css`. The **editor platform interfaces** (`editor.ts`) are extended to accommodate this feature, specifically allowing the **`changesView`** (`changesView.ts`) to render and integrate file opening logic within this new sidebar. This **new capability** significantly enhances the user experience by providing a dedicated space for reviewing session changes directly alongside the main editor content. | Mar 29 | 4 | grow |
| 3b664fd5 | This commit introduces a **visual enhancement** to the **sessions UI**, specifically targeting **chat editors** when they are displayed within **floating windows**.
