## Summary
Extract repeated patterns from 12 subgraph Playwright spec files into
shared test utilities, reducing duplication by ~142 lines.
## Changes
- **What**: New shared helpers for common subgraph test operations:
- `SubgraphHelper`: `getSlotCount()`, `getSlotLabel()`, `removeSlot()`,
`findSubgraphNodeId()`
- `NodeReference`: `delete()`
- `subgraphTestUtils`: `serializeAndReload()`,
`convertDefaultKSamplerToSubgraph()`, `expectWidgetBelowHeader()`,
`collectConsoleWarnings()`, `packAllInteriorNodes()`
- Replaced ~72 inline `page.evaluate` blocks and multi-line sequences
with single helper calls across 12 spec files
## Review Focus
- Behavioral equivalence: every replacement is a mechanical extraction
with no test logic changes
- API surface of new helpers: naming, parameter types, placement in
existing utility classes
- Whether any remaining inline patterns in the spec files would benefit
from further extraction

## Summary
Adds a `@perf` test to establish a baseline for viewport panning GC
churn on large graphs.
## Changes
- **What**: New `large graph viewport pan sweep` perf test that pans
aggressively back and forth across a 245-node graph, forcing many nodes
to cross the viewport boundary. Measures style recalcs, forced layouts,
task duration, heap delta, and DOM node count.
## Review Focus
This is **PR 1 of 2** (perf-fix-with-proof pattern). The fix (viewport
culling) will follow in a separate PR once this baseline is established
on main. CI will then show the delta proving the improvement.
The test uses 120 steps out + 120 steps back at 8px/step = ~960px total
displacement, enough to sweep across a significant portion of the large
graph layout.

## 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
Harden subgraph test coverage: remove low-value change-detector tests,
consolidate fixtures, add behavioral coverage, and fix test
infrastructure issues. Includes minor production code corrections
discovered during test hardening.
## Changes
- **What**: Comprehensive subgraph test suite overhaul across 6 phases
- Removed change-detector tests and redundant assertions
- Consolidated fixture helpers into `subgraphHelpers.ts` /
`subgraphFixtures.ts`
- Added Pinia initialization and fixture reset to all test files
- Fixed barrel import violations (circular dependency prevention)
- Added behavioral coverage for slot connections, events, edge cases
- Added E2E helper and smoke test for subgraph promotion
- Exported `SubgraphSlotBase` from litegraph barrel for test access
- **Production code changes** (minor correctness fixes found during
testing):
- `resolveSubgraphInputLink.ts`: iterate forward (first-connected-wins)
to match `_resolveLinkedPromotionBySubgraphInput`
- `promotionSchema.ts`: return `[]` instead of throwing on invalid
`proxyWidgets`; console.warn always (not DEV-only)
- `LGraph.ts`: disconnect-after-veto ordering fix
- `litegraph.ts`: barrel export swap for `SubgraphSlotBase`
- **Stats**: 349 tests passing, 0 skipped across 26 test files
## Review Focus
- Tests that merely asserted default property values were deleted
(change detectors)
- Fixture state is now reset via `resetSubgraphFixtureState()` in
`beforeEach`
- All imports use `@/lib/litegraph/src/litegraph` barrel to avoid
circular deps
- Production changes are small and directly motivated by test findings

## Summary
Add a permanent, non-failing performance regression detection system
using Chrome DevTools Protocol metrics, with automatic PR commenting.
## Changes
- **What**: Performance testing infrastructure — `PerformanceHelper`
fixture class using CDP `Performance.getMetrics` to collect
`RecalcStyleCount`, `LayoutCount`, `LayoutDuration`, `TaskDuration`,
`JSHeapUsedSize`. Adds `@perf` Playwright project (Chromium-only,
single-threaded, 60s timeout), 4 baseline perf tests, CI workflow with
sticky PR comment reporting, and `perf-report.js` script for generating
markdown comparison tables.
## Review Focus
- `PerformanceHelper` uses `page.context().newCDPSession(page)` — CDP is
Chromium-only, so perf metrics are not collected on Firefox. This is
intentional since CDP gives us browser-level style recalc/layout counts
that `performance.mark/measure` cannot capture.
- The CI workflow uses `continue-on-error: true` so perf tests never
block merging.
- Baseline comparison uses `dawidd6/action-download-artifact` to
download metrics from the target branch, following the same pattern as
`pr-size-report.yaml`.
## Stack
This is the foundation PR for the Firefox performance fix stack:
1. **→ This PR: perf testing infrastructure**
2. `perf/fix-cursor-cache` — cursor style caching (depends on this)
3. `perf/fix-subgraph-svg` — SVG pre-rasterization (depends on this)
4. `perf/fix-clippath-raf` — RAF batching for clip-path (depends on
this)
PRs 2-4 are independent of each other.

## 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)

- 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.
