## Summary
Refactors the error system to improve separation of concerns, fix DDD
layer violations, and address code quality issues.
- Extract `missingNodesErrorStore` from `executionErrorStore`, removing
the delegation pattern that coupled missing-node logic into the
execution error store
- Extract `useNodeErrorFlagSync` composable for node error flag
reconciliation (previously inlined)
- Extract `useErrorClearingHooks` composable with explicit callback
cleanup on node removal
- Extract `useErrorActions` composable to deduplicate telemetry+command
patterns across error card components
- Move `getCnrIdFromNode`/`getCnrIdFromProperties` to
`platform/nodeReplacement` layer (DDD fix)
- Move `missingNodesErrorStore` to `platform/nodeReplacement` (DDD
alignment)
- Add unmount cancellation guard to `useErrorReport` async `onMounted`
- Return watch stop handle from `useNodeErrorFlagSync`
- Add `asyncResolvedIds` eviction on `missingNodesError` reset
- Add `console.warn` to silent catch blocks and empty array guard
- Hoist `useCommandStore` to setup scope, fix floating promises
- Add `data-testid` to error groups, image/video error spans, copy
button
- Update E2E tests to use scoped locators and testids
- Add unit tests for `onNodeRemoved` restoration and double-install
guard
Fixes#9875, Fixes#10027, Fixes#10033, Fixes#10085
## Test plan
- [x] Existing unit tests pass with updated imports and mocks
- [x] New unit tests for `useErrorClearingHooks` (callback restoration,
double-install guard)
- [x] E2E tests updated to use scoped locators and `data-testid`
- [ ] Manual: verify error tab shows runtime errors and missing nodes
correctly
- [ ] Manual: verify "Find on GitHub", "Copy", and "Get Help" buttons
work in error cards

## 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
