## Summary
Extends `useNodeReplacement.test.ts` with five connection-transfer and
graph-mutation edge cases that the existing 23-case suite did not cover:
missing-old-input-slot skip, missing-new-output-index resilience,
set_value on a non-existent widget, set_value with dot-notation new_id,
and the Vue-node refresh path via `nodeGraph.onNodeAdded`.
## Changes
- **What**: Adds 5 Vitest cases in a new `transfer edge cases` describe
block. Reuses the existing `createPlaceholderNode`, `createNewNode`,
`createMockGraph`, `createMockLink`, and `makeMissingNodeType` helpers —
no new test infrastructure introduced.
## Review Focus
- The "missing new output index" test verifies that `replaceWithMapping`
does not throw when `newNode.outputs[newOutputIdx]` is absent, and
asserts the original link's `origin_id` is unchanged so the silent-skip
behavior is pinned (not a swallowed exception).
- The dot-notation `set_value` test pins that the existing dot-notation
guard at `useNodeReplacement.ts:203` covers the `set_value` branch (not
just the `old_id` connection branch already covered at line 187).
- The `onNodeAdded` test asserts the Vue-node sync path that runs after
`replaceWithMapping` bypasses `graph.add()` — a future refactor that
drops the explicit call would silently break the Vue node renderer
otherwise.
## Testing
\`\`\`bash
pnpm exec vitest run

## Summary
Muted and bypassed nodes are excluded from execution but were still
triggering missing model/media/node warnings. This PR makes the error
system mode-aware: muted/bypassed nodes no longer produce missing asset
errors, and all error lifecycle events (mode toggle, deletion, paste,
undo, tab switch) are handled consistently.
- Fixes Comfy-Org/ComfyUI#13256
## Behavioral notes
- **Tab switch overlay suppression (intentional)**: Switching back to a
workflow with missing assets no longer re-shows the error overlay. This
reverses the behavior introduced in #10190. The error state is still
restored silently in the errors tab — users can access it via the
properties panel without being interrupted by the overlay on every tab
switch.
## Changes
### 1. Scan filtering
- `scanAllModelCandidates`, `scanAllMediaCandidates`,
`scanMissingNodes`: skip nodes with `mode === NEVER || BYPASS`
- `collectMissingNodes` (serialized data): skip error reporting for
muted/bypassed nodes while still calling `sanitizeNodeName` for safe
`configure()`
- `collectEmbeddedModelsWithSource`: skip muted/bypassed nodes;
workflow-level `graphData.models` only create candidates when active
nodes exist
- `enrichWithEmbeddedMetadata`: filter unmatched workflow-level models
when all referencing nodes are inactive
### 2. Realtime mode change handling
- `useErrorClearingHooks.ts` chains `graph.onTrigger` to detect
`node:property:changed` (mode)
- Deactivation (active → muted/bypassed): remove missing
model/media/node errors for the node
- Activation (muted/bypassed → active): scan the node and add confirmed
errors, show overlay
- Subgraph container deactivation: remove all interior node errors
(execution ID prefix match)
- Subgraph container activation: scan all active interior nodes
recursively
- Subgraph interior mode change: resolve node via
`localGraph.getNodeById()` then compute execution ID from root graph
### 3. Node deletion
- `graph.onNodeRemoved`: remove missing model/media/node errors for the
deleted node
- Handle `node.graph === null` at callback time by using
`String(node.id)` for root-level nodes
### 4. Node paste/duplicate
- `graph.onNodeAdded`: scan via `queueMicrotask` (deferred until after
`node.configure()` restores widget values)
- Guard: skip during `ChangeTracker.isLoadingGraph` (undo/redo/tab
switch handled by pipeline)
- Guard: skip muted/bypassed nodes
### 5. Workflow tab switch optimization
- `skipAssetScans` option in `loadGraphData`: skip full pipeline on tab
switch
- Cache missing model/media/node state per workflow via
`PendingWarnings`
- `beforeLoadNewGraph`: save current store state to outgoing workflow's
`pendingWarnings`
- `showPendingWarnings`: restore cached errors silently (no overlay),
always sync missing nodes store (even when null)
- Preserve UI state (`fileSizes`, `urlInputs`) on tab switch by using
`setMissingModels([])` instead of `clearMissingModels()`
- `MissingModelRow.vue`: fetch file size on mount via
`fetchModelMetadata` memory cache
### 6. Undo/redo overlay suppression
- `silentAssetErrors` option propagated through pipeline →
`surfaceMissingModels`/`surfaceMissingMedia` `{ silent }` option
- `showPendingWarnings` `{ silent }` option for missing nodes overlay
- `changeTracker.ts`: pass `silentAssetErrors: true` on undo/redo
### 7. Error tab node filtering
- Selected node filters missing model/media card contents (not just
group visibility)
- `isAssetErrorInSelection`: resolve execution ID → graph node for
selection matching
- Missing nodes intentionally unfiltered (pack-level scope)
- `hasMissingMediaSelected` added to `RightSidePanel.vue` error tab
visibility
- Download All button: show only when 2+ downloadable models exist
### 8. New store functions
- `missingModelStore`: `addMissingModels`, `removeMissingModelsByNodeId`
- `missingMediaStore`: `addMissingMedia`, `removeMissingMediaByNodeId`
- `missingNodesErrorStore`: `removeMissingNodesByNodeId`
- `missingModelScan`: `scanNodeModelCandidates` (extracted single-node
scan)
- `missingMediaScan`: `scanNodeMediaCandidates` (extracted single-node
scan)
### 9. Test infrastructure improvements
- `data-testid` on `RightSidePanel.vue` tabs (`panel-tab-{value}`)
- Error-related TestIds moved from `dialogs` to `errorsTab` namespace in
`selectors.ts`
- Removed unused `TestIdValue` type
- Extracted `cleanupFakeModel` to shared `ErrorsTabHelper.ts`
- Renamed `openErrorsTabViaSeeErrors` → `loadWorkflowAndOpenErrorsTab`
- Added `aria-label` to pencil edit button and subgraph toggle button
## Test plan
### Unit tests (41 new)
- Store functions: `addMissing*`, `removeMissing*ByNodeId`
- `executionErrorStore`: `surfaceMissing*` silent option
- Scan functions: muted/bypassed filtering, `scanNodeModelCandidates`,
`scanNodeMediaCandidates`
- `workflowService`: `showPendingWarnings` silent, `beforeLoadNewGraph`
caching
### E2E tests (17 new in `errorsTabModeAware.spec.ts`)

## Summary
- Replace all `as unknown as Type` assertions in 59 unit test files with
type-safe `@total-typescript/shoehorn` functions
- Use `fromPartial<Type>()` for partial mock objects where deep-partial
type-checks (21 files)
- Use `fromAny<Type>()` for fundamentally incompatible types: null,
undefined, primitives, variables, class expressions, and mocks with
test-specific extra properties that `PartialDeepObject` rejects
(remaining files)
- All explicit type parameters preserved so TypeScript return types are
correct
- Browser test `.spec.ts` files excluded (shoehorn unavailable in
`page.evaluate` browser context)
## Verification
- `pnpm typecheck` ✅
- `pnpm lint` ✅
- `pnpm format` ✅
- Pre-commit hooks passed (format + oxlint + eslint + typecheck)
- Migrated test files verified passing (ran representative subset)
- No test behavior changes — only type assertion syntax changed
- No UI changes — screenshots not applicable

## Summary
Resolves six open issues by reorganizing node replacement components
into a domain-driven folder structure, refactoring event handling to
follow the emit pattern, and adding comprehensive test coverage across
all affected modules.
## Changes
- **What**:
- Moved `SwapNodeGroupRow.vue` and `SwapNodesCard.vue` from
`src/components/rightSidePanel/errors/` to
`src/platform/nodeReplacement/components/` (Issues #9255)
- Moved `useMissingNodeScan.ts` from `src/composables/` to
`src/platform/nodeReplacement/missingNodeScan.ts`, renamed to reflect it
is a plain function not a Vue composable (Issues #9254)
- Refactored `SwapNodeGroupRow.vue` to emit a `'replace'` event instead
of calling `useNodeReplacement()` and `useExecutionErrorStore()`
directly; replacement logic now handled in `TabErrors.vue` (Issue #9267)
- Added unit tests for `removeMissingNodesByType`
(`executionErrorStore.test.ts`), `scanMissingNodes`
(`missingNodeScan.test.ts`), and `swapNodeGroups` computed
(`swapNodeGroups.test.ts`, `useErrorGroups.test.ts`) (Issue #9270)
- Added placeholder detection tests covering unregistered-type detection
when `has_errors` is false, and exclusion of registered types
(`useNodeReplacement.test.ts`) (Issue #9271)
- Added component tests for `MissingNodeCard` and `MissingPackGroupRow`
covering rendering, expand/collapse, events, install states, and edge
cases (Issue #9231)
- Added component tests for `SwapNodeGroupRow` and `SwapNodesCard`
(Issues #9255, #9267)
## Additional Changes (Post-Review)
- **Edge case guard in placeholder detection**
(`useNodeReplacement.ts`): When `last_serialization.type` is absent (old
serialization format), the predicate falls back to `n.type`, which the
app may have already run through `sanitizeNodeName` — stripping HTML
special characters (`& < > " ' \` =`). In that case, a `Set.has()`
lookup against the original unsanitized type name would silently miss,
causing replacement to be skipped.
Fixed by including sanitized variants of each target type in the
`targetTypes` Set at construction time. For the overwhelmingly common
case (no special characters in type names), the Set deduplicates the
entries and runtime behavior is identical to before.
A regression test was added to cover the specific scenario:
`last_serialization.type` absent + live `n.type` already sanitized.
## Review Focus
- `TabErrors.vue`: confirm the new `@replace` event handler correctly
replaces nodes and removes them from missing nodes list (mirrors the old
inline logic in `SwapNodeGroupRow`)
- `missingNodeScan.ts`: filename/export name change from
`useMissingNodeScan` — verify all call sites updated via `app.ts`
- Test mocking strategy: module-level `vi.mock()` factories use closures
over `ref`/plain objects to allow per-test overrides without global
mutable state
- Fixes#9231
- Fixes#9254
- Fixes#9255
- Fixes#9267
- Fixes#9270
- Fixes#9271
## Summary
Fixes two bugs in the node replacement flow: placeholder detection
failing after workflow execution or pack reinstallation, and missing UI
sync in the Errors Tab when replacements are applied from the modal
dialog.
## Changes
- **Placeholder detection**: Node placeholder detection now matches
against `targetTypes` (derived from the replaceable node list built at
workflow load time) instead of relying on `has_errors` flag or
`registered_node_types` lookup. This ensures replacement works reliably
after execution (where `has_errors` gets cleared) and after pack
reinstallation (where the type becomes registered).
- **Modal → Errors Tab sync**: Added
`executionErrorStore.removeMissingNodesByType()` call in
`MissingNodesContent.vue` after replacement, so the Errors Tab reflects
changes immediately without requiring a page reload.
## Review Focus
- `collectAllNodes` predicate change in `useNodeReplacement.ts`: now
uses `targetTypes.has(originalType)` to find nodes by their original
serialized type. This is independent of runtime state like `has_errors`
or `registered_node_types`.
- `executionErrorStore.removeMissingNodesByType` call timing in
`MissingNodesContent.vue` — runs synchronously after
`replaceNodesInPlace` resolves, before auto-close logic.

by [Unito](https://www.unito.io)
## Summary
Adds a node replacement UI to the Errors Tab so users can swap missing
nodes with compatible alternatives directly from the error panel,
without opening a separate dialog.
## Changes
- **What**: New `SwapNodesCard` and `SwapNodeGroupRow` components render
swap groups in the Errors Tab; each group shows the missing node type,
its instances (with locate buttons), and a Replace button. Added
`useMissingNodeScan` composable to scan the graph for missing nodes and
populate `executionErrorStore`. Added `removeMissingNodesByType()` to
`executionErrorStore` so replaced nodes are pruned from the error list
reactively.
## Bug Fixes Found During Implementation
### Bug 1: Replaced nodes render as empty shells until page refresh
`replaceWithMapping()` directly mutates `_nodes[idx]`, bypassing the Vue
rendering pipeline entirely. Because the replacement node reuses the
same ID, `vueNodeData` retains the stale entry from the old placeholder
(`hasErrors: true`, empty widgets/inputs). `graph.setDirtyCanvas()` only
repaints the LiteGraph canvas and has no effect on Vue.
**Fix**: After `replaceWithMapping()`, manually call
`nodeGraph.onNodeAdded?.(newNode)` to trigger `handleNodeAdded` in
`useGraphNodeManager`, which runs `extractVueNodeData(newNode)` and
updates `vueNodeData` correctly. Also added a guard in `handleNodeAdded`
to skip `layoutStore.createNode()` when a layout for the same ID already
exists, preventing a duplicate `spatialIndex.insert()`.
### Bug 2: Missing node error list overwritten by incomplete server
response
Two compounding issues: (A) the server's `missing_node_type` error only
reports the *first* missing node — the old handler parsed this and
called `surfaceMissingNodes([singleNode])`, overwriting the full list
collected at load time. (B) `queuePrompt()` calls `clearAllErrors()`
before the API request; if the subsequent rescan used the stale
`has_errors` flag and found nothing, the missing nodes were permanently
lost.
**Fix**: Created `useMissingNodeScan.ts` which scans
`LiteGraph.registered_node_types` directly (not `has_errors`). The
`missing_node_type` catch block in `app.ts` now calls
`rescanAndSurfaceMissingNodes(this.rootGraph)` instead of parsing the
server's partial response.
## Review Focus
- `handleReplaceNode` removes the group from the store only when
`replaceNodesInPlace` returns at least one replaced node — should we
always clear, or only on full success?
- `useMissingNodeScan` re-scans on every execution-error change; confirm
no performance concerns for large graphs with many subgraphs.

by [Unito](https://www.unito.io)
## Summary
- Node replacements were never loaded because
`useNodeReplacementStore().load()` was called before `api.init()`,
meaning `serverFeatureFlags` was always empty at that point
- Dispatch `feature_flags` as a custom event from `api.ts` and trigger
`load()` in response within `addApiUpdateHandlers()`
## Changes
- **`api.ts`**: Dispatch `feature_flags` custom event after storing
server feature flags (already typed in `BackendApiCalls`)
- **`app.ts`**: Replace eager `load()` call with `feature_flags` event
listener inside `addApiUpdateHandlers()`, consistent with other API
event handlers
- **`nodeReplacementStore.ts`**: Use `api.getServerFeature()` directly
instead of `useFeatureFlags` composable; remove side effects from store
setup
- **`nodeReplacementStore.test.ts`**: Update mocks to match new
`api.getServerFeature` usage
## Review Focus
- Initialization ordering: listener registered before `api.init()`
ensures no missed events

by [Unito](https://www.unito.io)
## Summary
Gates the node replacement store's `load()` call behind the
`node_replacements` server feature flag, so the frontend only calls
`/api/node_replacements` when the backend advertises support.
## Changes
- Added `NODE_REPLACEMENTS = 'node_replacements'` to `ServerFeatureFlag`
enum
- Added `nodeReplacementsEnabled` getter to `useFeatureFlags()`
- Added `api.serverSupportsFeature('node_replacements')` guard in
`useNodeReplacementStore.load()`
## Context
Without this guard, the frontend would attempt to fetch node
replacements from backends that don't support the endpoint, causing 404
errors.

## Summary
Add node replacement UI to the missing nodes dialog. Users can select
and replace deprecated/missing nodes with compatible alternatives
directly from the dialog.
## Changes
- Classify missing nodes into **Replaceable** (quick fix) and **Install
Required** sections
- Add select-all checkbox + per-node checkboxes for batch replacement
- `useNodeReplacement` composable handles in-place node replacement on
the graph:
- Simple replacement (configure+copy) for nodes without mapping
- Input/output connection remapping for nodes with mapping
- Widget value transfer via `old_widget_ids`
- Dot-notation input handling for Autogrow/DynamicCombo
- Undo/redo support via `changeTracker` (try/finally)
- Title and properties preservation
- Footer UX: "Skip for Now" button when all nodes are replaceable (cloud
+ OSS)
- Auto-close dialog when all replaceable nodes are replaced and no
non-replaceable remain
- Settings navigation link from "Don't show again" checkbox
- 505-line unit test suite for `useNodeReplacement`
## Review Focus
- `useNodeReplacement.ts` — core graph manipulation logic
- `MissingNodesContent.vue` — checkbox selection state management
- `MissingNodesFooter.vue` — conditional button rendering (cloud vs OSS
vs all-replaceable)

## Summary
- Extend `MissingNodeType` with `isReplaceable` and `replacement` fields
- Classify missing nodes by checking
`nodeReplacementStore.getReplacementFor()` during graph load
- Wrap hardcoded node patches (T2IAdapterLoader, ConditioningAverage,
etc.) in `if (!isEnabled)` guard so they only run when node replacement
setting is disabled
- Change `useNodeReplacementStore().load()` from fire-and-forget
(`void`) to `await` so replacement data is available before missing node
detection
- Fix guard condition order in `nodeReplacementStore.load()`: check
`isEnabled` before `isLoaded`
- Align `InputMap` types with actual API response (flat
`old_id`/`set_value` fields instead of nested `assign` wrapper)
## Test plan
- [x] Load workflow with deprecated nodes (T2IAdapterLoader,
Load3DAnimation, SDV_img2vid_Conditioning)
- [x] Verify missing nodes are classified with `isReplaceable: true` and
`replacement` object
- [x] Verify hardcoded patches only run when node replacement setting is
OFF
- [x] Verify `nodeReplacementStore.load()` is not called when setting is
disabled
- [x] Unit tests pass (`nodeReplacementStore.test.ts` - 16 tests)
- [x] Typecheck passes
