## Summary
Promoted primitive subgraph inputs (String, Int) render their link
anchor at the header position instead of the widget row. Renaming
subgraph input labels breaks the match entirely, causing connections to
detach from their widgets visually.
## Changes
- **What**: Fix widget-input slot positioning for promoted subgraph
inputs in both LiteGraph and Vue (Nodes 2.0) rendering modes
- `_arrangeWidgetInputSlots`: Removed Vue mode branch that skipped
setting `input.pos`. Promoted widget inputs aren't rendered as
`<InputSlot>` Vue components (NodeSlots filters them out), so
`input.pos` is the only position fallback
- `drawConnections`: Added pre-pass to arrange nodes with unpositioned
widget-input slots before link rendering. The background canvas renders
before the foreground canvas calls `arrange()`, so positions weren't set
on the first frame
- `SubgraphNode`: Sync `input.widget.name` with the display name on
label rename and initial setup. The `IWidgetLocator` name diverged from
`PromotedWidgetView.name` after rename, breaking all name-based
slot↔widget matching (`_arrangeWidgetInputSlots`, `getWidgetFromSlot`,
`getSlotFromWidget`)
## Review Focus
- The `_arrangeWidgetInputSlots` rewrite iterates `_concreteInputs`
directly instead of building a spread-copy map — simpler and avoids the
stale index issue
- `input.widget.name` is now kept in sync with the display name
(`input.label ?? subgraphInput.name`). This is a semantic shift from
using the raw internal name, but it's required for all name-based
matching to work after renames. The value is overwritten on deserialize
by `_setWidget` anyway
- The `_widget` fallback in `_arrangeWidgetInputSlots` is a safety net
for edge cases where the name still doesn't match (e.g., stale cache)

## Summary
Fix node layout drift from repeated `ensureCorrectLayoutScale` scaling,
simplify it to a pure one-time normalizer, and fix links not following
Vue nodes during drag.
## Changes
- **What**:
- `ensureCorrectLayoutScale` simplified to a one-time normalizer:
unprojects legacy Vue-scaled coordinates back to canonical LiteGraph
coordinates, marks the graph as corrected, and does nothing else. No
longer touches the layout store, syncs reroutes, or changes canvas
scale.
- Removed no-op calls from `useVueNodeLifecycle.ts` (a renderer version
string was passed where an `LGraph` was expected).
- `layoutStore.finalizeOperation` now calls `notifyChange` synchronously
instead of via `setTimeout`. This ensures `useLayoutSync`'s `onChange`
callback pushes positions to LiteGraph `node.pos` and calls
`canvas.setDirty()` within the same RAF frame as a drag update, fixing
links not following Vue nodes during drag.
- **Tests**: Added tests for `ensureCorrectLayoutScale` (idempotency,
round-trip, unknown-renderer no-op) and `graphRenderTransform`
(project/unproject round-trips, anchor caching).
## Review Focus
- The `setTimeout(() => this.notifyChange(change), 0)` →
`this.notifyChange(change)` change in `layoutStore.ts` is the key fix
for the drag-link-sync bug. The listener (`useLayoutSync`) only writes
to LiteGraph, not back to the layout store, so synchronous notification
is safe.
- `ensureCorrectLayoutScale` no longer has any side effects beyond
normalizing coordinates and setting `workflowRendererVersion` metadata.

## Summary
Changes the layout store to treat node sizes as body-only measurements
while LiteGraph continues to reason about full heights. DOM-driven
updates are tagged with `LayoutSource.DOM`, which lets the store strip
the title height exactly once before persisting. That classification (a
new mutation source - `LayoutSource.DOM`) is accurate because those
mutations are triggered by the browser’s layout engine via
ResizeObserver, rather than by direct calls into the layout APIs (e.g.,
`moveNodeTo`, `useNodeDrag`). So all sources are:
- `LayoutSource.DOM`: browser layout/ResizeObserver measurements that
include the title bar
- `LayoutSource.Vue`: direct Vue-driven mutations routed through the
layout store
- `LayoutSource.Canvas`: legacy LiteGraph/canvas updates that will be
phased out over time
- `LayoutSource.External`: for multiplayer or syncing with a when going
online after making changes offline (in teams/workspace)
When layout state flows back into LiteGraph we add the title height just
in time for `liteNode.setSize`, so LiteGraph’s rendering stays
unchanged. This makes Vue node resizing and workflow persistence
deterministic - multiline widgets hold their dimensions across reloads
because every path that crosses the layout/LiteGraph boundary performs
the same normalization.

## Summary
**Problem:** ensureCorrectLayoutScale scales up LG -> Vue. But doesn't
scale down from Vue -> LG.
**Solution:** Bi directional scaling.
**Bonus:** fix edge cases such as subgraphs, groups, and reroutes. Also,
set auto scale: true now that we 'preserve' LG scale.
**IMPORTANT:** useVueNodeResizeTracking.ts sets vue node height -
Litegraph.NODE_TITLE_HEIGHT on workflow load using a resize observer.
Reloading the page (loading a workflow) in Vue mode, will subtract
height each time. This can look like a problem caused by
ensureCorrectLayoutScale. It is not. Need to fix. Here was an attempt by
[removing the Litegraph.NODE_TITLE_HEIGHT
entirely](https://github.com/Comfy-Org/ComfyUI_frontend/pull/6643).
## Review Focus
Full lifecycle of loading workflows and switching between vue and lg.
Race conditions could be present. For example switching the mode using
keybind very fast.

## Summary
### Problem:
The Vue nodes renderer/feature introduces new designs for each node i.e.
the equivalent Litegraph node design is smaller and the vue node design
is non uniformly larger.
### Example:
Litegraph Ksampler node: 200w x 220h
<img width="200" height="220" alt="image"
src="https://github.com/user-attachments/assets/eef0117b-7e02-407d-98ab-c610fd1ec54c"
/>
Vue Node Ksampler node: 445w x 430h
<img width="445" height="430" alt="image"
src="https://github.com/user-attachments/assets/e78d9d45-5b32-4e8d-bf1c-bce1c699037f"
/>
This means if users load a workflow in Litegraph and then switches to
Vue nodes renderer the nodes are using the same Litegraph positions
which would cause a visual overlap and overall look broken.
### Example:
<img width="1510" height="726" alt="image"
src="https://github.com/user-attachments/assets/3b7ae9d2-6057-49b2-968e-c531a969fac4"
/>
<img width="1475" height="850" alt="image"
src="https://github.com/user-attachments/assets/ea10f361-09bd-4daa-97f1-6b45b5dde389"
/>
### Solution:
Scale the positions of the nodes in lite graph radially from the center
of the bounds of all nodes. And then simply move the Vue nodes to those
new positions.
1. Get the `center of the bounds of all LG nodes`.
2. Get the `xy of each LG node`.
3. Get the vector from `center of the bounds of all LG nodes` `-` `xy of
each LG node`.
4. Scale it by a factor (e.g. 1.75x which is the average Vue node size
increase plus some visual padding.)
5. Move each Vue node to the scaled `xy of each LG node`.
Result: The nodes are spaced apart removing overlaps while keeping the
spatial layout intact.

src="https://github.com/user-attachments/assets/7817d866-4051-47bb-a589-69ca77a0bfd3"
/>
### Further concerns.
This vector scaling algorithm needs to run once per workflow when in vue
nodes. This means when in Litegraph and switching to Vue nodes, it needs
to run before the nodes render. And then now that the entire app is in
vue nodes, we need to run it each time we load a workflow. However, once
its run, we do not need to run it again. Therefore we must persist a
flag that it has run somewhere. This PR also adds that feature by
leveraging the `extra` field in the workflow schema.

## Summary
The private fields triggered an error in intitializing the
linkLayoutSync. Turns out that wasn't necessary anymore.
> [!NOTE]
> Edit: Doing some more investigation, it looks like the slot sync can
also be removed?
## Changes
- **What**: Converts JS private fields to typescript private, adds some
readonly declarations
- **What**: Removes the useLinkLayoutSync usage in useVueNodeLifecycle
- **What**: Removes the useSlotLayoutSync usage in useVueNodeLifecycle
## Review Focus
Was the sync doing something that wouldn't be caught in normal
usage/testing?

by [Unito](https://www.unito.io)
## Summary
Cleanup and fixes to the existing syncing logic.
## Review Focus
This is probably enough to review and test now.
Main things that should still work:
- moving nodes around
- adding new ones
- switching back and forth between Vue and Litegraph
Let me know if you find any bugs that weren't already present there.

by [Unito](https://www.unito.io)
## Summary
Prerequisite refactor/cleanup to use a global store instead of having
nodes throw up events to a parent component that stores a reference to a
singleton service that itself bootstraps and synchronizes with a
separate service to maintain a partially reactive but not fully reactive
set of states that describe some but not all aspects of the nodes on
either the litegraph, the vue side, or both.
## Changes
- **What**: Refactoring, the behavior should not change.
- **Dependencies**: A type utility to help with Vue component props
## Review Focus
Is there something about the current structure that this could affect
that would not be caught by our tests or using the application?

* [refactor] Improve renderer architecture organization
Building on PR #5388, this refines the renderer domain structure:
**Key improvements:**
- Group all transform utilities in `transform/` subdirectory for better cohesion
- Move canvas state to dedicated `renderer/core/canvas/` domain
- Consolidate coordinate system logic (TransformPane, useTransformState, sync utilities)
**File organization:**
- `renderer/core/canvas/canvasStore.ts` (was `stores/graphStore.ts`)
- `renderer/core/layout/transform/` contains all coordinate system utilities
- Transform sync utilities co-located with core transform logic
This creates clearer domain boundaries and groups related functionality
while building on the foundation established in PR #5388.
