## Summary
Replace the Proxy-based proxy widget system with a store-driven
architecture where `promotionStore` and `widgetValueStore` are the
single sources of truth for subgraph widget promotion and widget values,
and `SubgraphNode.widgets` is a synthetic getter composing lightweight
`PromotedWidgetView` objects from store state.
## Motivation
The subgraph widget promotion system previously scattered state across
multiple unsynchronized layers:
- **Persistence**: `node.properties.proxyWidgets` (tuples on the
LiteGraph node)
- **Runtime**: Proxy-based `proxyWidget.ts` with `Overlay` objects,
`DisconnectedWidget` singleton, and `isProxyWidget` type guards
- **UI**: Each Vue component independently calling `parseProxyWidgets()`
via `customRef` hacks
- **Mutation flags**: Imperative `widget.promoted = true/false` set on
`subgraph-opened` events
This led to 4+ independent parsings of the same data, complex cache
invalidation, and no reactive contract between the promotion state and
the rendering layer. Widget values were similarly owned by LiteGraph
with no Vue-reactive backing.
The core principle driving these changes: **Vue owns truth**. Pinia
stores are the canonical source; LiteGraph objects delegate to stores
via getters/setters; Vue components react to store state directly.
## Changes
### New stores (single sources of truth)
- **`promotionStore`** — Reactive `Map<NodeId, PromotionEntry[]>`
tracking which interior widgets are promoted on which SubgraphNode
instances. Graph-scoped by root graph ID to prevent cross-workflow state
collision. Replaces `properties.proxyWidgets` parsing, `customRef`
hacks, `widget.promoted` mutation, and the `subgraph-opened` event
listener.
- **`widgetValueStore`** — Graph-scoped `Map<WidgetKey, WidgetState>`
that is the canonical owner of widget values. `BaseWidget.value`
delegates to this store via getter/setter when a node ID is assigned.
Eliminates the need for Proxy-based value forwarding.
### Synthetic widgets getter (SubgraphNode)
`SubgraphNode.widgets` is now a getter that reads
`promotionStore.getPromotions(rootGraphId, nodeId)` and returns cached
`PromotedWidgetView` objects. No stubs, no Proxies, no fake widgets
persisted in the array. The setter is a no-op — mutations go through
`promotionStore`.
### PromotedWidgetView
A class behind a `createPromotedWidgetView` factory, implementing the
`PromotedWidgetView` interface. Delegates value/type/options/drawing to
the resolved interior widget and stores. Owns positional state (`y`,
`computedHeight`) for canvas layout. Cached by
`PromotedWidgetViewManager` for object-identity stability across frames.
### DOM widget promotion
Promoted DOM widgets (textarea, image upload, etc.) render on the
SubgraphNode surface via `positionOverride` in `domWidgetStore`.
`DomWidgets.vue` checks for overrides and uses the SubgraphNode's
coordinates instead of the interior node's.
### Promoted previews
New `usePromotedPreviews` composable resolves image/audio/video preview
widgets from promoted entries, enabling SubgraphNodes to display
previews of interior preview nodes.
### Deleted
- `proxyWidget.ts` (257 lines) — Proxy handler, `Overlay`,
`newProxyWidget`, `isProxyWidget`
- `DisconnectedWidget.ts` (39 lines) — Singleton Proxy target
- `useValueTransform.ts` (32 lines) — Replaced by store delegation
### Key architectural changes
- `BaseWidget.value` getter/setter delegates to `widgetValueStore` when
node ID is set
- `LGraph.add()` reordered: `node.graph` assigned before widget
`setNodeId` (enables store registration)
- `LGraph.clear()` cleans up graph-scoped stores to prevent stale
entries across workflow switches
- `promotionStore` and `widgetValueStore` state nested under root graph
UUID for multi-workflow isolation
- `SubgraphNode.serialize()` writes promotions back to
`properties.proxyWidgets` for persistence compatibility
- Legacy `-1` promotion entries resolved and migrated on first load with
dev warning
## Test coverage
- **3,700+ lines of new/updated tests** across 36 test files
- **Unit**: `promotionStore.test.ts`, `widgetValueStore.test.ts`,
`promotedWidgetView.test.ts` (921 lines),
`subgraphNodePromotion.test.ts`, `proxyWidgetUtils.test.ts`,
`DomWidgets.test.ts`, `PromotedWidgetViewManager.test.ts`,
`usePromotedPreviews.test.ts`, `resolvePromotedWidget.test.ts`,
`subgraphPseudoWidgetCache.test.ts`
- **E2E**: `subgraphPromotion.spec.ts` (622 lines) — promote/demote,
manual/auto promotion, paste preservation, seed control augmentation,
image preview promotion; `imagePreview.spec.ts` extended with
multi-promoted-preview coverage
- **Fixtures**: 2 new subgraph workflow fixtures for preview promotion
scenarios
## Review focus
- Graph-scoped store keying (`rootGraphId`) — verify isolation across
workflows/tabs and cleanup on `LGraph.clear()`
- `PromotedWidgetView` positional stability — `_arrangeWidgets` writes
to `y`/`computedHeight` on cached objects; getter returns fresh array
but stable object references
- DOM widget position override lifecycle — overrides set on promote,
cleared on demote/removal/subgraph navigation
- Legacy `-1` entry migration — resolved and written back on first load;
unresolvable entries dropped with dev warning
- Serialization round-trip — `promotionStore` state →
`properties.proxyWidgets` on serialize, hydrated back on configure
## Diff breakdown (excluding lockfile)
- 153 files changed, ~7,500 insertions, ~1,900 deletions (excluding
pnpm-lock.yaml churn)
- ~3,700 lines are tests
- ~300 lines deleted (proxyWidget.ts, DisconnectedWidget.ts,
useValueTransform.ts)

## Summary
Extracts error-related state and logic from `executionStore` into a
dedicated `executionErrorStore` for better separation of concerns.
## Changes
- **New store**: `executionErrorStore` with all error state
(`lastNodeErrors`, `lastExecutionError`, `lastPromptError`), computed
properties (`hasAnyError`, `totalErrorCount`,
`activeGraphErrorNodeIds`), and UI state (`isErrorOverlayOpen`,
`showErrorOverlay`, `dismissErrorOverlay`)
- **Moved util**: `executionIdToNodeLocatorId` extracted to
`graphTraversalUtil`, reusing `traverseSubgraphPath` and accepting
`rootGraph` as parameter
- **Updated consumers**: 12 files updated to import from
`executionErrorStore`
- **Backward compat**: Deprecated getters retained in `ComfyApp` for
extension compatibility
## Review Focus
- Deprecated getters in `app.ts` — can be removed in a future
breaking-change PR once extension authors migrate

#8598 made primitve widgets connected to an asset have the asset type,
but the `nodeType` parameter required to actually resolve valid models
wasn't getting passed correctly.
This `nodeType`, introduced by me back in #7576, was a mistake. I'm
pulling it out now and instead passing nodeType as an option. Of note:
code changes are only required to pass the option, not to utilize it.

The backport PR was made first in #8878. Fixing the bug was time
sensitive and backport would not be clean due to the `widget.value`
changes. Changes were still simpler than expected. I probably should
have made this PR first and then backported, but I misjudged the
complexity of conflict resolution.

- "Enter Subgraph" "Show advanced inputs" and a new "show node Errors"
button now use a combined button design at the bottom of the node.
- A new "Errors" tab is added to the right side panel
- After a failed queue, the label of an invalid widget is now red.
- Badges other than price are now displayed on the bottom of the node.
- Price badge will now truncate from the first space, prioritizing the
sizing of the node title
- An indicator for the node resize handle is now displayed while mousing
over the node.

## 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

In vue mode, the VHS Load Audio (Upload) node had 2 audio previews. This
occurred because the native AudioPreview widget was being applied to any
combo widget with the name `audio`. This native preview does not support
the advanced preview functions VHS provides like seeking to specific
start time, trimming to a target duration, or converting from formats
the browser may not support.
This is fixed through a fairly involved cleanup to instead display the
litegraph AudioUI widget as an AudioPreview widget when in vue mode.

Did testing on about a dozen custom nodes. Most just work.
- Some custom nodes have copy/pasted the `addDOMWidget` call with types
like `customtext` and get converted to textareas -> Not feasible to fix
here. Can open PRs into custom nodes if complaints arise.
- Only the KJNodes spline editor had mouse issues -> Can
investigate/open PR into KJNodes later.
- Many nodes don't resize gracefully. Probably best handled in a future
PR.
- Some expect to be handled like textareas. These currently have minsize
and don't scale.
- Others, like VHS previews, scale self properly, but don't update
height inside a drag operation -> node height can be set to less than
fit.

This pull request introduces a new audio playback widget for node UIs
and integrates it into the node widget system. The main changes include
the implementation of the `WidgetAudioUI` component, its registration in
the widget registry, and updates to pass node data to the new widget.
Additionally, some logging was added for debugging purposes.
**Audio Widget Implementation and Integration:**
* Added a new `WidgetAudioUI.vue` component that provides audio playback
controls (play/pause, progress slider, volume, options) and loads audio
files from the server based on node data.
* Registered the new `WidgetAudioUI` component in the widget registry by
importing it and adding an entry for the `audioUI` type.

* Updated `NodeWidgets.vue` to pass `nodeInfo` as the `node-data` prop
to widgets of type `audioUI`, enabling the widget to access
node-specific audio file information.
**Debugging and Logging:**
* Added logging of `nodeData` in `LGraphNode.vue` and
`WidgetAudioUI.vue` to help with debugging and understanding the data
structure.

## Summary
Fixes https://github.com/Comfy-Org/ComfyUI_frontend/issues/5692 by
making widget link connection status trigger on change so Vue widgets
with connected links could properly switch to the `disabled` state when
they are implicitly converted to inputs.
## Changes
- **What**: Added `node:slot-links:changed` event tracking and reactive
slot data synchronization for Vue widgets

## Summary
Replaced reactive (Vue-based) widget LOD with CSS visibility control.
Performance doesn't dramatically improve, but we avoid the mount/unmount
overhead during zoom/pan operations. This PR implements the visual
component of LOD—complex widgets that need lifecycle management will be
addressed separately.
### Problem & Solution
Problem: we want LOD to improve rendering performance and visual
feedback but discovered using reactivity in the current setup for it
meant mounting/unmounting caused worse lag than the performance it aimed
to fix. Switching to render all the details all the time but using css
visibility proved to be the best solution. However, it doesn't improve
rendering performance by much because the GPU texture size is the
bottleneck (from TransformPane.vue CSS transforms) and not
rasterization.
Solution: Keep all nodes/widgets mounted, use CSS visibility: hidden for
LOD. Trade memory for performance stability during zoom/pan/drag
operations.
### Technical Decision
We chose Performance > Memory:
- CSS transforms create a single GPU texture whose size depends on node
count, not widget complexity
- Mounting/unmounting hundreds of widgets during zoom = noticeable lag
from Vue VDOM diffing (since all components are mounted all the time
because of viewport culling challenge/trade off see
https://github.com/Comfy-Org/ComfyUI_frontend/pull/5510.)
- CSS visibility changes = no reactivity overhead, smooth interactions
- Result: Similar performance, but without interaction stutters
This is the visual layer only. If we want a hook into the LOD state per
node / widget that would be the next follow up system to implement.
### Next Steps (maybe)
- Chunked (split up single Transform Pane transform layer) when
rendering 1000+ nodes (maybe)
- ~~Selective unmounting API for widgets that register as "expensive"~~
- ~~Client bound hydration system~~
