## Summary
Normalize legacy prefixed proxyWidget entries during subgraph configure
so nested subgraph widgets resolve correctly.
## Changes
- **What**: Extract `normalizeLegacyProxyWidgetEntry` to strip legacy
`nodeId: innerNodeId: widgetName` prefixes from serialized proxyWidgets
and resolve the correct `disambiguatingSourceNodeId`. Write-back
comparison now checks serialized content (not just array length) so
stale formats are cleaned up even when the entry count is unchanged.
## Review Focus
- The iterative prefix-stripping loop in `resolveLegacyPrefixedEntry` —
it peels one `N: ` prefix per iteration and tries all disambiguator
candidates at each level.
- The write-back condition change from length comparison to
`JSON.stringify` equality.

## Summary
Packing nodes inside a subgraph into a nested subgraph no longer blanks
the parent subgraph node's promoted widget values.
## Changes
- **What**: After `convertToSubgraph` moves interior nodes into a nested
subgraph, `_repointAncestorPromotions` rewrites the promotion store
entries on all host SubgraphNodes so they chain through the new nested
node. `rebuildInputWidgetBindings()` then clears the stale
`input._widget` PromotedWidgetView cache and re-resolves bindings from
current connections.
- The root cause was two separate sets of PromotedWidgetView references:
`node.widgets` (rebuilt from the store — correct) vs `input._widget`
(cached at promotion time — stale). `SubgraphNode.serialize()` reads
`input._widget.value`, which resolved against removed node IDs →
`missing-node` → blank values on the next `checkState` cycle.
## Review Focus
- `_repointAncestorPromotions` iterates all graphs to find host nodes of
the current subgraph type — verify this covers all cases (multiple
instances of the same subgraph type).
- `rebuildInputWidgetBindings()` clears `_promotedViewManager` and
re-resolves — confirm no side effects on event listeners or pending
promotions.
- The nested node gets duplicate promotion entries (from both
`_repointAncestorPromotions` and `promoteRecommendedWidgets` via the
`subgraph-converted` event). `store.promote()` deduplicates via
`isPromoted`, but worth verifying.

## Summary
Prune stale proxyWidgets entries that reference grandchild nodes no
longer present in the outer subgraph after nested packing.
## Changes
- **What**: Filter out proxyWidgets entries during hydration when the
source node doesn't exist in the subgraph. Also skip missing-node
entries in `_pruneStaleAliasFallbackEntries` as defense-in-depth. Write
back cleaned entries so stale data doesn't persist.
## Review Focus
The fix touches two codepaths in `SubgraphNode.ts`:
1. **Hydration** (`_internalConfigureAfterSlots`): Added `getNodeById`
guard before accepting a proxyWidget entry, and broadened the write-back
condition from legacy-only to any filtered entries.
2. **Runtime pruning** (`_pruneStaleAliasFallbackEntries`): Added
early-exit for entries whose source node no longer exists — previously
these survived because failed resolution returned `undefined` which
bypassed the concrete-key comparison.

## 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 multiple issues with promoted widget resolution in nested subgraphs,
ensuring correct value propagation, slot matching, and rendering for
deeply nested promoted widgets.
## Changes
- **What**: Stabilize nested subgraph promoted widget resolution chain
- Use deep source keys for promoted widget values in Vue rendering mode
- Resolve effective widget options from the source widget instead of the
promoted view
- Stabilize slot resolution for nested promoted widgets
- Preserve combo value rendering for promoted subgraph widgets
- Prevent subgraph definition deletion while other nodes still reference
the same type
- Clean up unused exported resolution types
## Review Focus
- `resolveConcretePromotedWidget.ts` — new recursive resolution logic
for deeply nested promoted widgets
- `useGraphNodeManager.ts` — option extraction now uses
`effectiveWidget` for promoted widgets
- `SubgraphNode.ts` — unpack no longer force-deletes definitions
referenced by other nodes

## 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,

## Summary
Fix subgraph unpacking creating spurious links to widget inputs (e.g.
seed) when the subgraph contains ComfySwitchNode with duplicate internal
links.
## Changes
- **What**: Two fixes in `_unpackSubgraphImpl`:
1. Strip links from serialized node data **before** `configure()` so
`onConnectionsChange` doesn't resolve subgraph-internal link IDs against
the parent graph's link map (which may contain unrelated links with
colliding numeric IDs).
2. Deduplicate links by `(origin, origin_slot, target, target_slot)`
before reconnecting, preventing repeated disconnect/reconnect cycles on
widget inputs that cause slot index drift.
## Review Focus
- The link-stripping before `configure()` mirrors what
`LGraphNode.clone()` already does — nodes should be configured without
stale link references when links will be recreated separately.
- Deduplication is defensive against malformed subgraph data; the
duplicate links in the reproduction workflow likely originated from a
prior serialization bug.

## Summary
Add `ensureGlobalIdUniqueness` to reassign duplicate node IDs across
subgraphs when loading workflows, gated behind an experimental setting.
## Changes
- **What**: Shared `LGraphState` between root graph and subgraphs so ID
counters are global. Added `ensureGlobalIdUniqueness()` method that
detects and remaps colliding node IDs in subgraphs, preserving root
graph IDs as canonical and patching link references. Gated behind
`Comfy.Graph.DeduplicateSubgraphNodeIds` (experimental, default
`false`).
- **Dependencies**: None
## Review Focus
- Shared state override on `Subgraph` (getter delegates to root, setter
is no-op) — verify no existing code sets `subgraph.state` directly.
- `Math.max` state merging in `configure()` prevents ID counter
regression when loading subgraph definitions.
- Feature flag wiring: static property on `LGraph`, synced from settings
via `useLitegraphSettings`.

## Cause
When graphs are actually exported, several layers of cleanup are
applied. Among these is link compression. Any widgets with inputs that
aren't used do not have inputs stored in the workflow. This was
implemented for backwards compatibility with the old "convert to input"
system for widgets. As part of this process, the target_slots on links
are rewritten such that they point to the index of the widget as if
unconnected widgets did not exist.
This "incorrect" state for links is only corrected AFTER a workflow has
loaded because the 'fix' method needs nodes to be initialized in order
to calculate the correct target_slot
This becomes a problem when subgraphs are introduced. SubgraphInputs
need to resolve a link to its target slot in order to construct a clone
of the linked widget DURING the loading process. Since this target slot
is not accurate, this can result in the cloned widget having the wrong
type.
For a minimal reproduction:
- Create a subgraph with an Empty Latent Image with batch_size linked to
the Subgraph Input
- Export the workflow
- On load, the batch_size has step and min attributes which incorrectly
correspond to width
## Fix
There's multiple possible ways to address this and input on direction is
appreciated
- Fix links before loading graph
- Likely to break with any dynamic state
- Fix links, then load graph again
- Ugly, bad performance, dynamic state may require multiple passes to
correctly ripple
- In the Subgraph code, ignore target_slot and instead `.find()` input
with matching linkId (proposed)
- Promising, but means accepting that state is just wrong sometimes.
Another forever footgun.
- Entirely remove the input compression
- Some people may complain, and old workflows still need to be supported
- Only remove target_slot redirection inside subgraphs
- Creates ugly logical difference between what happens inside and
outside subgraphs.
- Still leaves old workflows broken
