## Summary
Improved type safety in test files by eliminating unsafe type assertions
and adopting official testing patterns. Reduced unsafe `as unknown as`
type assertions and eliminated all `null!` assertions.
## Changes
- **Adopted @pinia/testing patterns**
- Replaced manual Pinia store mocking with `createTestingPinia()` in
`useSelectionState.test.ts`
- Eliminated ~120 lines of mock boilerplate
- Created `createMockSettingStore()` helper to replace duplicated store
mocks in `useCoreCommands.test.ts`
- **Eliminated unsafe null assertions**
- Created explicit `MockMaskEditorStore` interface with proper nullable
types in `useCanvasTools.test.ts`
- Replaced `null!` initializations with `null` and used `!` at point of
use or `?.` for optional chaining
- **Made partial mock intent explicit**
- Updated test utilities in `litegraphTestUtils.ts` to use explicit
`Partial<T>` typing
- Changed cast pattern from `as T` to `as Partial<T> as T` to show
incomplete mock intent
- Applied to `createMockLGraphNode()`, `createMockPositionable()`, and
`createMockLGraphGroup()`
- **Created centralized mock utilities** in
`src/utils/__tests__/litegraphTestUtils.ts`
- `createMockLGraphNode()`, `createMockPositionable()`,
`createMockLGraphGroup()`, `createMockSubgraphNode()`
- Updated 8+ test files to use centralized utilities
- Used union types `Partial<T> | Record<string, unknown>` for flexible
mock creation
## Results
- ✅ 0 typecheck errors
- ✅ 0 lint errors
- ✅ All tests passing in modified files
- ✅ Eliminated all `null!` assertions
- ✅ Reduced unsafe double-cast patterns significantly

## Summary
- Type `onExecuted` callbacks with `NodeExecutionOutput` in saveMesh.ts
and uploadAudio.ts
- Type composable parameters and return values properly
(useLoad3dViewer, useImageMenuOptions, useJobMenu, useResultGallery,
useContextMenuTranslation)
- Type `taskRef` as `TaskItemImpl` with updated test mocks
- Fix error catch and index signature patterns without `any`
- Add `NodeOutputWith<T>` generic helper for typed access to passthrough
properties on `NodeExecutionOutput`
## Test plan
- [x] `pnpm typecheck` passes
- [x] `pnpm lint` passes
- [x] Unit tests pass for affected files
- [x] Sourcegraph checks confirm no external usage of modified types

# Canvas Rotation and Mirroring
## Overview
Adds rotation (90° left/right) and mirroring (horizontal/vertical)
capabilities to the mask editor canvas. All three layers (image, mask,
RGB) transform together. Redo and Undo respect transformations as new
states. Keyboard shortcuts also added for all four functions in
Keybinding settings.
Additionally, fixed the issue of ctrl+z and ctrl+y keyboard commands not
restricting to the mask editor canvas while opened.

## What Changed
### New Files
- **`src/composables/maskeditor/useCanvasTransform.ts`**
- Core transformation logic for rotation and mirroring
- GPU texture recreation after transformations
### Modified Files
#### **`src/composables/useCoreCommands.ts`**
- Added check to see if Mask Editor is opened for undo and redo commands
#### **`src/stores/maskEditorStore.ts`**
- Added GPU texture recreation signals
#### **`src/composables/maskeditor/useBrushDrawing.ts`**
- Added watcher for `gpuTexturesNeedRecreation` signal
- Handles GPU texture recreation when canvas dimensions change
- Recreates textures with new dimensions after rotation
- Updates preview canvas and readback buffers accordingly
- Ensures proper ArrayBuffer backing for WebGPU compatibility
#### **`src/components/maskeditor/TopBarHeader.vue`**
- Added 4 new transform buttons with icons:
- Rotate Left (counter-clockwise)
- Rotate Right (clockwise)
- Mirror Horizontal
- Mirror Vertical
- Added visual separators between button groups
#### **`src/extensions/core/maskEditor.ts`**
- Added keyboard shortcut settings for rotate and mirror
#### **Translation Files** (e.g., `src/locales/en.json`)
- Added i18n keys:

## Summary
Migrates all unit tests from `tests-ui/` to colocate with their source
files in `src/`, improving discoverability and maintainability.
## Changes
- **What**: Relocated all unit tests to be adjacent to the code they
test, following the `<source>.test.ts` naming convention
- **Config**: Updated `vitest.config.ts` to remove `tests-ui` include
pattern and `@tests-ui` alias
- **Docs**: Moved testing documentation to `docs/testing/` with updated
paths and patterns
## Review Focus
- Migration patterns documented in
`temp/plans/migrate-tests-ui-to-src.md`
- Tests use `@/` path aliases instead of relative imports
- Shared fixtures placed in `__fixtures__/` directories

Prior to the release of subgraphs, there was a single graph accessed
through `app.graph`. Now that there's multiple graphs, there's a lot of
code that needs to be reviewed and potentially updated depending on if
it cares about nearby nodes, all nodes, or something else requiring
specific attention.
This was done by simply changing the type of `app.graph` to unknown so
the typechecker will complain about every place it's currently used.
References were then updated to `app.rootGraph` if the previous usage
was correct, or actually rewritten.
By not getting rid of `app.graph`, this change already ensures that
there's no loss of functionality for custom nodes, but the prior typing
of `app.graph` can always be restored if future dissuasion of
`app.graph` usage creates issues.

## Summary
This PR refactors the mask editor from a vanilla JavaScript
implementation to Vue 3 + Composition API, aligning it with the ComfyUI
frontend's modern architecture. This is a structural refactor without UI
changes - all visual appearances and user interactions remain identical.
Net change: +1,700 lines (mostly tests)
## Changes
- Converted from class-based managers to Vue 3 Composition API
- Migrated state management to Pinia stores (maskEditorStore,
maskEditorDataStore)
- Split monolithic managers into focused composables:
- useBrushDrawing - Brush rendering and drawing logic
- useCanvasManager - Canvas lifecycle and operations
- useCanvasTools - Tool-specific canvas operations
- usePanAndZoom - Pan and zoom functionality
- useToolManager - Tool selection and coordination
- useKeyboard - Keyboard shortcuts
- useMaskEditorLoader/Saver - Data loading and saving
- useCoordinateTransform - Coordinate system transformations
- Replaced imperative DOM manipulation with Vue components
- Added comprehensive test coverage
## What This PR Does NOT Change
Preserved Original Styling:
- Original CSS retained in packages/design-system/src/css/style.css
- Some generic controls (DropdownControl, SliderControl, ToggleControl)
preserved as-is
- Future migration to Tailwind and PrimeVue components is planned but
out of scope for this PR
Preserved Core Functionality:
- Drawing algorithms and brush rendering logic remain unchanged
- Pan/zoom calculations preserved
- Canvas operations (composite modes, image processing) unchanged
- Tool behaviors (brush, color select, paint bucket) identical
- No changes to mask generation or export logic
DO NOT Review:
- CSS styling choices (preserved from original)
- Drawing algorithm implementations (unchanged)
- Canvas rendering logic (ported as-is)
- UI/UX changes (none exist)
- Component library choices (future work)
