The core fix is correct -- verified by 8 parallel review agents. clearRunErrors() no longer clears missing nodes, clean() is the right graph-discard hook, the A1111 bypass is properly compensated, no clearAllErrors references remain, and all 4 mutation-proved claims check out.
Findings that could not be pinned inline (files not in PR diff):
suggestion: (non-blocking) src/composables/graph/useErrorClearingHooks.ts:365-367 -- this manually ORs hasMissingModels || hasMissingMedia || hasMissingNodes, which is the exact definition of hasMissingError now exported from executionErrorStore. A future fourth resource type would need updating in two places. Consider replacing the inline OR with useExecutionErrorStore().hasMissingError.
note: (non-blocking) src/scripts/changeTracker.ts:472 -- updateState() calls loadGraphData(prevState, false, false, ...) with clean=false, which skips clean() and therefore setMissingNodeTypes([]). Before this PR, the next submission would incidentally wipe stale missing-node state from undo. Now submissions no longer clear it, so stale rows from an undone graph can persist indefinitely. Pre-existing gap, not a regression here -- but worth a follow-up (calling setMissingNodeTypes([]) or rescanAndSurfaceMissingNodes in updateState after restoring the graph).
suggestion: (non-blocking) src/stores/executionErrorStore.test.ts:805 -- the nodes case in the hasMissingError tests seeds state via useMissingNodesErrorStore().missingNodesError = fromAny({}), writing directly to an internal ref and bypassing setMissingNodeTypes. The models and media cases use the public arrays consistently. Consider: useMissingNodesErrorStore().setMissingNodeTypes([{ type: 'TestNode', hint: '' }]).
nitpick: (non-blocking) src/stores/executionErrorStore.test.ts:830 -- 'excludes node validation errors' is a misleading title. hasMissingError has no connection to lastNodeErrors so this passes trivially. 'returns false when only node validation errors exist' would be clearer.

issue: Reflect.set(singletonApp, 'rootGraphInternal', graph) mutates the live exported app singleton. vi.resetAllMocks() does not undo Reflect.set, so the patched graph can leak into tests that run after this block. The same pattern appears at lines 306, 372, 824, 861, 927, 1032, 1736 (all pre-existing), but the new A1111 block adds another instance.
Since importA1111 is fully mocked here, check whether the singleton patch is necessary. If not, remove it. If yes, add teardown:

Removed — it was unnecessary, not just risky.
You were right to ask rather than assume: with importA1111 mocked, nothing in this test reads singletonApp.rootGraph. I deleted the line and the test still passes, so there was no teardown to write.
Leaving the eight pre-existing instances alone; they are outside this diff and at least one of them looks load-bearing.

suggestion: (non-blocking) The A1111 tests cover the success path (callback fires, setMissingNodeTypes([]) runs) and several failure modes. One gap: no test asserts that missing-node state is NOT cleared when importA1111 returns 'not-a1111' or 'core-nodes-unavailable' (without calling beforeGraphClear). The PR description says "a failed import keeps the current state" -- that is correct by inspection, but consider adding a test case:

Added, for both outcomes:
it.for(['not-a1111', 'core-nodes-unavailable'] as const)(
'keeps missing node packs when the import fails with %s',
async (outcome) => {
missingNodesStore.setMissingNodeTypes(['OutgoingMissingNode'])
mockImportA1111.mockResolvedValue(outcome)
await app.handleFile(createTestFile('a1111.png', 'image/png'))
expect(missingNodesStore.missingNodesError?.nodeTypes).toEqual([
'OutgoingMissingNode'
])
}
)Worth doing because the PR description asserted it and nothing pinned it. Mutation check: hoisting the clear out of the callback so it runs unconditionally fails both cases.

nitpick: (non-blocking) Per project AGENTS.md: justification comments on single-line fixes should be removed. The commit message already explains the A1111 path in depth, and the test name 'clears missing node packs, which its graph swap skips clean() for' is the right home for prose explanation.

suggestion: (non-blocking) If useWorkflowService().beforeLoadNewGraph() throws (thumbnail capture, draft persist, etc.), setMissingNodeTypes([]) on the next line is skipped and stale rows persist for the new graph. beforeLoadNewGraph reads missingNodesError to snapshot it into pendingWarnings before the clear, so reordering is unsafe -- a try/finally preserves the ordering while guaranteeing the clear always fires:
Low production risk today (no current path throws here), but structurally correct.

Applied. Your reasoning about the ordering is the part that made this worth doing — beforeLoadNewGraph snapshots missingNodesError into pendingWarnings, so the clear genuinely cannot move ahead of it, and try/finally is the only shape that keeps the order while guaranteeing the clear.
try {
useWorkflowService().beforeLoadNewGraph()
} finally {
useMissingNodesErrorStore().setMissingNodeTypes([])
}I did not want to ship it as speculative defence, so I checked it means something: a temporary test made beforeLoadNewGraph throw and asserted the state was still cleared. It passes with the finally and fails without it. Probe removed after.

suggestion: (non-blocking) clean() now calls useMissingNodesErrorStore().setMissingNodeTypes([]) directly, as does the A1111 callback at line 2025. executionErrorStore already holds the missingNodesStore reference internally -- a thin clearGraphErrors() method there (combining clearRunErrors() + missingNodesStore.setMissingNodeTypes([])) would give both sites a single call and remove the new direct missingNodesErrorStore import from app.ts. If a fourth missing-resource type is added later, one place to update instead of two.

Agreed on the direction, deferring it — and I want to be explicit about why rather than just declining.
An earlier version of this PR did exactly this: a shared reset covering all three stores, called from clean() and the other graph-discard sites. It was abandoned. Three independent unbriefed reviews found five defects in it, all on the model/media side: clean() empties the stores but never syncs pendingWarnings, so a later showPendingWarnings() resurrects them; per-node removal has the same gap from the other direction; clean() does not abort in-flight verification, so a late pipeline result repopulates an emptied store; sharing the abort controller passed a signal that was then never re-checked after the await; and the A1111 path bypassed the whole thing for models and media.
The root of it is that missing nodes are a synchronous derived fact — one ref, no async, no controller — while models and media are the result of network verification that outlives the graph that started it, with a per-workflow cache and a two-tier repair state. A clearGraphErrors() that unifies the three reads as tidier and quietly puts models and media on a path they have never been on.
So the same seam you are pointing at is the right one, but it wants a graph generation token and cache ownership to go with it, not just a combined call. That is written up and will be its own change. This PR stays at two production lines plus the A1111 compensation.

nitpick: (non-blocking) hasMissingError was already present and exported before this commit (HEAD~1 confirms it at line 397). The change here is that hasAnyError now delegates to it rather than inlining the three sub-flags -- which is an improvement. Worth correcting the PR description to avoid confusion for bisect/blame readers: the computed is not new.

Checked the description and there is nothing to correct — it does not mention hasMissingError or hasAnyError at all.
The delegation you are describing is also not in this diff. hasAnyError already delegated to hasMissingError at the base commit (7de29c4cf3); this branch was cut narrow and takes executionErrorStore.ts from there, so the only change to that file here is clearAllErrors → clearRunErrors losing its setMissingNodeTypes([]) line. git show 7de29c4cf3:src/stores/executionErrorStore.ts confirms it.
Flagging it in case it came from an earlier revision of this branch — there was one, and it did touch more of this file.

Pressing Run emptied the missing-node-pack rows from the Errors tab. The nodes were still missing; the panel just stopped saying so. `clearAllErrors` was shared by two callers with different needs — `queuePrompt`, which means "forget the last run", and `clean()`, which means "forget this graph" — and it cleared missing-node state for both. A submission carries no evidence about the environment: it does not check whether the pack was installed, so it cannot justify dropping the row. Move that one clear to `clean()`, which is reached by every path that replaces or discards the graph (`loadGraphData`, `loadApiJson`, Clear Workflow, the Clear button), and rename the function to `clearRunErrors` so its name matches what it now does. The A1111 import needs the clear spelled out: it replaces the graph from inside `importA1111` via a `beforeGraphClear` callback and never reaches `clean()`, so it already left the store describing the outgoing graph. That was survivable before only because the next submission happened to wipe it; with submissions no longer clearing, the stale rows would persist indefinitely. The callback runs after the parameters and required core nodes validate, so a failed import keeps the current state. Missing model and media state already followed this rule — `clearAllErrors` never touched it, and it is cleared in `loadGraphData` instead. This aligns missing nodes with the two resources that were already right, rather than changing when models or media are cleared.
- Guarantee the A1111 clear with try/finally. `beforeLoadNewGraph` snapshots `missingNodesError` into `pendingWarnings`, so the clear cannot move ahead of it; wrapping instead keeps the ordering and still fires if it throws. - Drop the `singletonApp` patch from the new A1111 test. `Reflect.set` survives `vi.resetAllMocks()`, and with `importA1111` mocked the patch was unused. - Cover the failed-import path: `not-a1111` and `core-nodes-unavailable` never reach the callback, so missing-node state must survive. The PR claimed this; nothing pinned it. - Reuse `hasMissingError` in `useErrorClearingHooks` instead of re-ORing the three stores, so a fourth resource type only has to be added once. - Seed the `hasMissingError` node case through `setMissingNodeTypes` rather than assigning the internal ref, matching the model and media cases, and rename `excludes node validation errors` to say what it asserts. - Remove two comments that restate the code they sit on.

Summary
Pressing Run emptied the missing-node-pack rows from the Errors tab; the nodes were still missing, the panel just stopped saying so.
Changes
clearAllErrorswas shared byqueuePrompt("forget the last run") andclean()("forget this graph"), and cleared missing-node state for both. A submission carries no evidence about the environment — it never checks whether the pack was installed — so it cannot justify dropping the row. The clear moves toclean(), and the function is renamedclearRunErrorsto match what it now does.Missing model and media state already followed this rule:
clearAllErrorsnever touched it, and it is cleared inloadGraphDatainstead. This aligns missing nodes with the two resources that were already right; it does not change when models or media are cleared.Production change is four lines.
Review Focus
Every discard path still clears.
clean()is reached byloadGraphData,loadApiJson,Comfy.ClearWorkflow(useCoreCommands.ts:279) and the legacy Clear button (ui.ts:680).Except one, which needed the clear spelled out. The A1111 import replaces the graph from inside
importA1111through abeforeGraphClearcallback and never reachesclean(), so it already left the store describing the outgoing graph. That was survivable only because the next submission happened to wipe it — with submissions no longer clearing, the stale rows would persist indefinitely.afterLoadNewGraphdoes not callshowPendingWarnings, so nothing else re-syncs that path. The callback runs after the parameters and required core nodes validate, so a failed import keeps the current state.What this deliberately does not do. An earlier version of this PR generalised the same rule to the missing-model and missing-media stores. It was abandoned: those two carry async verification that outlives the graph that started it, plus a per-workflow cache and a two-tier repair state, and unifying them produced five separate defects (cache resurrection after discard, cache not synced on per-node removal, verification not aborted, an abort whose signal was passed but never checked after the await, and the A1111 bypass for all three resources). None of that is in this PR. It is written up separately and will be its own change.
Verification
Four tests, each mutation-proved — revert the production line, watch the named test fail, restore, watch it pass:
clearRunErrorspreserves missing node packs when submitting a prompt, store test, E2Eclean()'s clearclears missing node packs when the graph is discardedclears missing node packs, which its graph swap skips clean() forqueuePrompt'sclearRunErrors()The E2E (
