## Summary
API and other legacy JSON generated by python `json.dumps` can contain
`NaN` and `Infinity` which cannot be parsed with JS `JSON.parse`. This
adds regex to replace these invalid tokens with `null`.
## Changes
- **What**:
- add regex replace on bare NaN/infinity tokens after JSON.parse fails
- update call sites
- tests
## Review Focus
- The regex should only rewrite bare NaN/-Infinity/Infinity and not
touch string values or other invalid tokens.
- A small regex was chosen over JSON5 due to package size (30.3kB
Minified, 9kB Minified + Gzipped) or a manual parser due to the
unnecessarily complexity vs a single regex replace.
- The happy path is run first, the safe parse is only executed if that
failed, meaning no overhead the vast majority of the time and no
possiblity of corrupting valid workflows due to a bug in the fallback
parser
- Multiple call sites had to be updated due to pre-existing architecture
of the various parsers, an issue for unifying these is logged for future
cleanup
- New binary fixtures added for validating e2e import using real files

## Summary
Adds 12 tests for `src/scripts/metadata/avif.ts`, raising line coverage
from **2.3% → 90.4%** (statements 88.5%, functions 93.3%).
## Test Coverage
Happy paths:
- Workflow JSON extracted from EXIF Exif item (LE)
- Prompt JSON extracted
- Big-endian (MM) EXIF parsing
- Both prompt and workflow present in separate EXIF entries
Negative paths (each yields `{}` without throwing):
- AVIF major brand is not "avif"
- Meta box missing
- iinf has no Exif item
- EXIF entry uses an unrecognized key
- EXIF entry has malformed JSON
- infe version is unsupported (1)
- iloc box missing while iinf has Exif
- Buffer too short for valid header
## Testing
\`\`\`bash
pnpm vitest run src/scripts/metadata/avif.test.ts
pnpm vitest run src/scripts/metadata/avif.test.ts --coverage
--coverage.include='src/scripts/metadata/avif.ts'

## Summary
- Replace 83 `as unknown as` double casts with safer alternatives across
33 files
- Use `as Partial<X> as X` pattern where TypeScript allows it
- Create/reuse factory functions from `litegraphTestUtils.ts` for mock
objects
- Widen `getWorkflowDataFromFile` return type to include `ComfyMetadata`
directly
- Reduce total `as unknown as` count from ~153 to 71
The remaining 71 occurrences are genuinely necessary due to cross-schema
casts, generic variance, missing index signatures, Float64Array-to-tuple
conversions, and DOM type incompatibilities.
## Test plan
- [x] `pnpm typecheck` passes
- [x] `pnpm lint` passes
- [x] All affected unit tests pass

## Summary
Implements Phase 1 of the **Vue-owns-truth** pattern for widget values.
Widget values are now canonical in a Pinia store; `widget.value`
delegates to the store while preserving full backward compatibility.
## Changes
- **New store**: `src/stores/widgetValueStore.ts` - centralized widget
value storage with `get/set/remove/removeNode` API
- **BaseWidget integration**: `widget.value` getter/setter now delegates
to store when widget is associated with a node
- **LGraphNode wiring**: `addCustomWidget()` automatically calls
`widget.setNodeId(this.id)` to wire widgets to their nodes
- **Test fixes**: Added Pinia setup to test files that use widgets
## Why
This foundation enables:
- Vue components to reactively bind to widget values via `computed(() =>
store.get(...))`
- Future Yjs/CRDT backing for real-time collaboration
- Cleaner separation between Vue state and LiteGraph rendering
## Backward Compatibility
| Extension Pattern | Status |
|-------------------|--------|
| `widget.value = x` | ✅ Works unchanged |
| `node.widgets[i].value` | ✅ Works unchanged |
| `widget.callback` | ✅ Still fires |
| `node.onWidgetChanged` | ✅ Still fires |
## Testing
- ✅ 4252 unit tests pass
- ✅ Build succeeds

## Summary
Fixes PNG iTXt chunk parsing to comply with the PNG specification.
## Problem
The current iTXt parser incorrectly reads the text content immediately
after the keyword null terminator, but iTXt chunks have additional
fields:
- Compression flag (1 byte)
- Compression method (1 byte)
- Language tag (null-terminated)
- Translated keyword (null-terminated)
- Text content
This caused PNGs that correctly follow the spec to fail loading with
JSON parse errors due to leading null bytes.
## Solution
Skip the compression flag, method, language tag, and translated keyword
fields before reading the text content.
Fixes#8150

## Summary
This PR removes unsafe type assertions ("as unknown as Type") from test
files and improves type safety across the codebase.
### Key Changes
#### Type Safety Improvements
- Removed all instances of "as unknown as" patterns from test files
- Used proper factory functions from litegraphTestUtils instead of
custom mocks
- Made incomplete mocks explicit using Partial<T> types
- Fixed DialogStore mocking with proper interface exports
- Improved type safety with satisfies operator where applicable
#### App Parameter Removal
- **Removed the unused `app` parameter from all ComfyExtension interface
methods**
- The app parameter was always undefined at runtime as it was never
passed from invokeExtensions
- Affected methods: init, setup, addCustomNodeDefs,
beforeRegisterNodeDef, beforeRegisterVueAppNodeDefs,
registerCustomNodes, loadedGraphNode, nodeCreated, beforeConfigureGraph,
afterConfigureGraph
##### Breaking Change Analysis
Verified via Sourcegraph that this is NOT a breaking change:
- Searched all 10 affected methods across GitHub repositories
- Only one external repository
([drawthingsai/draw-things-comfyui](https://github.com/drawthingsai/draw-things-comfyui))
declares the app parameter in their extension methods
- That repository never actually uses the app parameter (just declares
it in the function signature)
- All other repositories already omit the app parameter
- Search queries used:
- [init method
search](https://sourcegraph.com/search?q=context:global+repo:%5Egithub%5C.com/.*+lang:typescript+%22init%28app%22+-repo:Comfy-Org/ComfyUI_frontend&patternType=standard)
- [setup method
search](https://sourcegraph.com/search?q=context:global+repo:%5Egithub%5C.com/.*+lang:typescript+%22setup%28app%22+-repo:Comfy-Org/ComfyUI_frontend&patternType=standard)
- Similar searches for all 10 methods confirmed no usage
### Files Changed
Test files:
-
src/components/settings/widgets/__tests__/WidgetInputNumberInput.test.ts
- src/services/keybindingService.escape.test.ts
- src/services/keybindingService.forwarding.test.ts

-
src/renderer/extensions/vueNodes/widgets/composables/useIntWidget.test.ts
-

interface
- src/services/extensionService.ts - Improved type safety with
FunctionPropertyNames helper
- src/scripts/metadata/isobmff.ts - Fixed extractJson return type per
review
- src/extensions/core/*.ts - Updated extension implementations

## 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

## Summary
- Enable `verbatimModuleSyntax` compiler option in TypeScript
configuration
- Update all type imports to use explicit `import type` syntax
- This change will Improve tree-shaking and bundler compatibility
## Motivation
The `verbatimModuleSyntax` option ensures that type-only imports are
explicitly marked with the `type` keyword. This:
- Makes import/export intentions clearer
- Improves tree-shaking by helping bundlers identify what can be safely
removed
- Ensures better compatibility with modern bundlers
- Follows TypeScript best practices for module syntax
## Changes
- Added `"verbatimModuleSyntax": true` to `tsconfig.json`
- Updated another 48+ files to use explicit `import type` syntax for
type-only imports
- No functional changes, only import/export syntax improvements
## Test Plan
- [x] TypeScript compilation passes
- [x] Build completes successfully
- [x] Tests pass
- [ ] No runtime behavior changes

* [refactor] move workflow domain to its own folder
* [refactor] Fix workflow platform architecture organization
- Move workflow rendering functionality to renderer/thumbnail domain
- Rename ui folder to management for better semantic clarity
- Update all import paths to reflect proper domain boundaries
- Fix test imports to use new structure
Architecture improvements:
- rendering → renderer/thumbnail (belongs with other rendering logic)
- ui → management (better name for state management and UI integration)
This ensures proper separation of concerns and domain boundaries.
