Save the previous workflowId and workflowName before mutating state.
If saveToFile() fails, restore the previous values so the workflow
identity is unchanged.

Instead of mutating selectedOutputIndex N times in a loop (which races
with React renders), pass { arrayItemIndex: index } as an edge data
override through onConnect. Adds optional edgeDataOverrides parameter
to onConnect and addEdgeWithType.

When importing a workflow via file picker, loadWorkflow had no way to
find the image files on disk because directoryPath was only stored in
localStorage (which doesn't survive browser switches or clears).
Now auto-save embeds directoryPath in the workflow JSON, and
loadWorkflow uses it as a fallback after the workflowPath parameter
and localStorage config.

Saved workflows can contain multiple edges with the same ID (from
repeated connections or migration normalization). React warns about
duplicate keys and may render edges incorrectly. Deduplicate by
keeping the last occurrence of each edge ID on load.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Saved workflows could contain edges targeting nanoBanana nodes with
indexed handle IDs (image-0, text-0) from a previous schema-based
handle format. GenerateImageNode now always renders non-indexed
handles (image, text), causing React Flow error #008 on every
interaction. Normalize these edge handles during loadWorkflow.

- Register VideoFrameGrabNode in node exports, nodeTypes map, and minimap colors
- Add to ConnectionDropMenu as video target (Frame Grab) and image source
- Add executeVideoFrameGrab executor with canvas-based frame extraction
- Wire into all three execution paths: executeWorkflow, regenerateNode, executeSelectedNodes
- Add video connection validation for videoFrameGrab target type
- Add handle mapping for video->videoFrameGrab and videoFrameGrab->image connections
- Add videoFrameGrab case to quickstart validation defaults
Two fixes in pasteNodes:
1. Deep copy node data with JSON.parse/stringify (was shallow spread)
2. requestAnimationFrame selection correction to override React Flow's
stale selection reconciliation that could re-select original nodes
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The VideoTrim executor was missing from three places:
- execution/index.ts barrel export
- workflowStore.ts regenerateNode if-else chain
- workflowStore.ts executeSelectedNodes switch
This caused the Trim button to complete instantly with no processing
and no video output downstream.

* fix: additional PR review fixes — SSRF, data semantics, sync tracking, error propagation
Providers:
- replicate: add SSRF validation on mediaUrl before fetch
- fal/kie/replicate/wavespeed: large-video returns data="" with url set
instead of putting raw URL in data field (violates GenerationOutput.data semantic)
- kie: remove stale WaveSpeed JSDoc block from kie provider file
- route.ts: update all output handling to support data="" + url for large videos
Executors:
- generateVideoExecutor/nanoBananaExecutor: track save-generation fetch in
pendingImageSyncs via new trackSaveGeneration context method so auto-save
waits for server ID resolution
- videoProcessingExecutors: throw errors instead of returning in validation
branches (encoderSupported, insufficient videos, no video connected) so
Promise.allSettled sees rejections
- types.ts: add trackSaveGeneration to NodeExecutionContext interface
- workflowStore: wire trackSaveGeneration into both execution context sites

* feat: add keyboard shortcuts dialog and 3D GLB viewer node
- Keyboard shortcuts: press ? or click keyboard icon to view all shortcuts
- 3D GLB viewer: upload .GLB files, orbit/rotate, capture as image output
- Fix: restore trailing newline in gemini.ts provider
* fix: make Prompt node editable when connected to LLM node
When a Prompt node receives text from an LLM Generate node, the text
should be editable by the user. Previously, the textarea was marked as
readOnly when there was an incoming text connection, preventing edits
in both the main view and the expanded modal.
Changes:
- Track last received LLM output to detect when it changes
- Only update prompt when LLM node runs again (output changes)
- Allow user edits in between LLM runs
- Remove readOnly restriction on textarea
- Update placeholder text to indicate editability
This allows users to edit the LLM-generated text, which will be
replaced only when the LLM node runs again, not on every render.

branches (encoderSupported, insufficient videos, no video connected) so
Promise.allSettled sees rejections
- types.ts: add trackSaveGeneration to NodeExecutionContext interface
- workflowStore: wire trackSaveGeneration into both execution context sites

Fix video element not reloading on regeneration by adding key prop tied
to video history ID. Fix cancel showing timeout message by passing
"user-cancelled" reason through AbortController and checking it in all
three executor catch blocks.

Remove dead trackSaveGeneration function (no longer called after executor
extraction) and unused type imports. Store: 3,838 -> 1,721 lines (55% reduction).

Wire extracted executors into workflowStore, replacing the ~1000-line
switch statement in executeWorkflow and ~750-line if-else chain in
regenerateNode with executor registry calls. Store reduced from 3,402
to 1,782 lines.

Move getConnectedInputs (136 lines) and validateWorkflow (59 lines) into
connectedInputs.ts as pure functions taking (nodeId, nodes, edges).
Store methods become thin wrappers. Add 22 new tests.

Move groupNodesByLevel, chunk, revokeBlobUrl, clearNodeImageRefs,
and concurrency settings into executionUtils.ts with 21 new tests.

Replace 6 duplicated header-building if/else chains (across executeWorkflow
and regenerateNode) with buildGenerateHeaders() and buildLlmHeaders() utility
functions. Add 13 new tests.

The loopCount (1x/2x/3x) feature was only applied in executeWorkflow()
but not in regenerateNode(), which is the code path triggered by
clicking the "Stitch" button. This adds the blob duplication logic to
both code paths and includes the UI controls and type definitions.

- Refactor executeSingleNode error paths to throw instead of setting global
isRunning/currentNodeIds state, which corrupted sibling nodes running in
parallel via Promise.allSettled
- Validate WaveSpeed providedPollUrl with SSRF check before use
- Sanitize WaveSpeed taskId in provider with path-traversal validation
- Revoke blob URLs (URL.revokeObjectURL) before replacing outputVideo to
prevent memory leaks from large video files
- Move pause edge cleanup to outer executeWorkflow loop

- Replace RegExp constructor with replaceAll() for @variable substitution
in promptConstructor to prevent regex injection via variable names
- Wrap annotation, prompt, and promptConstructor execution cases in
try/catch to gracefully handle errors (log + set node error, continue)
- Fix MediaBunny resource cleanup type safety with closeable type guard

- AudioInputNode: use named event handlers with removeEventListener in cleanup
- deduplicatedFetch: track setTimeout IDs and clear them in clearFetchCache()
- waitForPendingImageSyncs: clear timeout in finally block after Promise.race
- decodeWithMediaBunny: wrap in try/finally to close sink, input, blobSource

Multiple node instances (GenerateImageNode, GenerateVideoNode, etc.) were
each making their own /api/models requests when mounted, causing N duplicate
network requests when N nodes existed on the canvas.
This fix:
- Adds deduplicatedFetch utility that shares in-flight requests to the same URL
- Adds useProviderApiKeys() hook with shallow equality for stable API key refs
- Updates all components to use primitive dependencies instead of object refs
- Uses deduplicatedFetch for all model-fetching operations
Expected result: 1 request instead of N when multiple nodes need the same data.

- Add fetchWithTimeout utility for image save requests (30s timeout)
- Process node images in parallel batches (3 at a time) for faster saves
- Add timeout to waitForPendingImageSyncs (60s) to prevent infinite hangs
- Move isSaving flag reset to finally block for consistent state cleanup

- Extract MIME type from data URL header when fetch() Blob loses it
- Create new Blob with correct type for MediaBunny format detection
- Fix both executeWorkflow and regenerateNode videoStitch paths
Ensure handles render in all node states (disabled/checking/normal) by
extracting a shared renderHandles function. Move clipOrder syncing from
useMemo side-effect into a proper useEffect. Add dynamic video handle
resolution in WorkflowCanvas for indexed handles. Add VideoStitch
execution case in regenerateNode.

- Add level-based topological sort (groupNodesByLevel) to identify
nodes that can execute concurrently
- Change state from currentNodeId to currentNodeIds[] for tracking
multiple executing nodes
- Execute nodes in batches using Promise.allSettled with configurable
concurrency limit (default 3, adjustable 1-10)
- Integrate AbortController for fail-fast cancellation on errors
- Pass abort signals to API fetch calls for proper request cancellation
- Update UI: multiple nodes show execution border, FloatingActionBar
shows "N nodes" during parallel execution
- Add concurrency slider in Project Settings > Node Defaults tab
- Store concurrency preference in localStorage
Workflows with independent generate nodes (e.g., 3 parallel image
generations) now complete in ~20-25s instead of ~60-90s sequential.

WorkflowCanvas.tsx:
- Import VideoStitchNode
- Add videoStitch to nodeTypes
- Add getNodeHandles case: inputs=["video", "audio"], outputs=["video"]
- Update isValidConnection to allow video→videoStitch connections
- Add minimap color: orange-500 (#f97316)
ConnectionDropMenu.tsx:
- Add videoStitch to VIDEO_TARGET_OPTIONS (first position)
- Add videoStitch to VIDEO_SOURCE_OPTIONS (produces video output)
- Add videoStitch to AUDIO_TARGET_OPTIONS (accepts audio input)
workflowStore.ts:
- Import VideoStitchNodeData type
- Add videoStitch to getSourceOutput (returns video type)
- Add executeWorkflow case for videoStitch with full stitching logic:
* Check encoder support
* Get connected inputs (videos, audio)
* Convert video data URLs to Blobs
* Prepare audio if connected (using prepareAudioAsync)
* Call stitchVideosAsync with progress callback
* Store output (blob URL for >20MB, data URL otherwise)
* Handle errors
Note: nodeDefaults.ts already had videoStitch dimensions and
createDefaultNodeData from Plan 02, so no changes needed there.
