- gemini: remove redundant header overrides, fix nano-banana model ID
- kie: module-level MAX_MEDIA_SIZE, post-download size check, upload size guard
- replicate: remove duplicate param spread, validate modelId format
- wavespeed: post-download size check, NaN-safe parseInt, prevent prompt overwrite
Executors:
- generateVideo: validate stored fallback inputs same as regular path
- nanoBanana: cap imageHistory at 50 entries
- splitGrid: handle img.onerror with warning + null data
- videoProcessing: add FileReader onerror/onabort handlers
Utilities:
- connectedInputs: use ?? instead of || for outputText/template
- executionUtils: guard orphan children in topological sort, validate chunk() size
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* 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

- replicate.ts: Increase polling timeout to 10 min for video models;
filter output array to valid strings before URL validation
- nanoBananaExecutor.ts: Replace read-modify-write on outputGallery with
atomic appendOutputGalleryImage using Zustand set() callback

* 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.

* fix: unwrap array inputs for non-array API parameters
When multiple images are connected to a generation node, dynamicInputs
aggregates them into arrays. Providers wrapped single values into arrays
for array-typed params, but never unwrapped arrays for string-typed params,
causing API failures (e.g. fal's image_url receiving an array instead of
a string). Add symmetric unwrap logic across all four providers.

* fix: clear imageRef when user provides new image to prevent stale saves
When a user pastes/uploads a new image into a node that already has a

image data is set so the save logic correctly persists the new image.

handleNodeDragStop used a hardcoded 300x280 fallback for node dimensions,
causing miscalculated centers for non-standard nodes (easeCurve 340x480,
videoStitch 400x280, audioInput 300x200). Now uses the same 3-level
fallback (measured → style → defaultNodeDimensions) as createGroup.

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.

The isRunning check and set were separated by an await, allowing a second
call to pass the guard during the async gap. Move set() before the await
to close the window.

Add applyEditOperations to workflowStore for AI-driven workflow modifications.
Wire ChatPanel to process editWorkflow tool calls and apply operations via store.
Pass lightweight workflow state to chat API for context-aware assistance.
Changes:
- workflowStore: add applyEditOperations method and EditOperation import
- ChatPanel: add onApplyEdits prop, workflowState prop, custom fetch wrapper
- ChatPanel: process tool-invocation parts for editWorkflow and createWorkflow
- ChatPanel: render tool explanations in chat UI
- WorkflowCanvas: extract chatWorkflowState, create handleApplyEdits callback
- WorkflowCanvas: pass onApplyEdits and workflowState to ChatPanel
AI edits trigger captureSnapshot before applying (revert button support).
AI edits do NOT increment manualChangeCount (only manual edits clear snapshot).

loadWorkflow was unconditionally calling clearSnapshot(), wiping the
snapshot that captureSnapshot() just saved. Add preserveSnapshot
option to loadWorkflow and pass it from the AI build workflow path
so the Revert AI Changes button actually appears.

Add defensive check before Object.keys(groups) in saveToFile and
exportWorkflow to prevent "Cannot read properties of undefined
(reading 'length')" when groups is undefined after AI workflow
generation.

state before AI-initiated changes. Includes manual change tracking
that auto-clears snapshot after 3 user edits.
- Add previousWorkflowSnapshot state (nodes, edges, groups, edgeStyle)
- Add manualChangeCount state
- Implement captureSnapshot() to save current workflow state
- Implement revertToSnapshot() to restore snapshot
- Implement clearSnapshot() to remove snapshot
- Implement incrementManualChangeCount() with auto-clear at 3 changes
- Wire manual change tracking into addNode, removeNode, onConnect,
removeEdge, onNodesChange (remove only), onEdgesChange (remove only)
- Call clearSnapshot() in clearWorkflow and loadWorkflow

React Flow's internal bounds for nodes were undefined, causing certain nodes
to be incorrectly included in drag selections regardless of their position.
Added statistical outlier detection using IQR to identify and automatically
deselect nodes that are clearly outside the actual selection area.
Also includes:
- Clear selected state and validate position coordinates on workflow load
- Strip selected property when saving workflows (transient UI state)
- Enable prompt nodes to receive text input connections

- Update getHandleType() to recognize indexed handles (text-0, image-0)
used by external providers like Replicate and fal.ai
- Fix validateWorkflow() to accept indexed text handles for nanoBanana nodes
- Add validation for generateVideo nodes requiring text input
- Use local state pattern in PromptNode to prevent cursor jumping during typing

Two related issues fixed:
1. Image history IDs not syncing before workflow save (PR#27 follow-up):
- Added pending sync tracking for save-generation API calls
- saveToFile() now awaits all pending syncs before saving
- Ensures imageHistory/videoHistory IDs match actual saved filenames
2. Duplicate images created on every save:
- After externalization, store nodes now receive the image refs
- Subsequent saves recognize existing refs and skip creating new files
- Prevents inputs/ and generations/ folders from accumulating duplicates

Enable storing default model and settings per node type in localStorage.
New nodes created via shortcuts will use these stored preferences.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The save-generation API changed to use prompt+hash based filenames for
deduplication, but the workflow store was still using timestamp-based IDs
in imageHistory/videoHistory. This caused the carousel to fail loading
images since the IDs didn't match the actual saved filenames.
Now we capture the API response and update the history entry with the
actual imageId returned by the save-generation endpoint. This is backward
compatible - old workflows with timestamp-based filenames continue to work.

Fixes issues with external provider models (e.g., seedream-4.5) where:
- Boolean/integer params with "image" in name were misclassified as image inputs
- Array params without items.type specification were incorrectly rejected
- Handle ID mismatch between node components (image-0) and store (image)
- dynamicInputs not passed to API in node regeneration code path
Changes:
- Update isImageInput() to check schema types, not just names
- Map both indexed (image-0) and legacy (image) handle IDs to schema names
- Add dynamicInputs to nanoBanana regeneration request body
- Add hidden backward-compat handles for edge routing
- Add comprehensive tests for schema classification and handle mapping
- Fix Toast test to use specific selector for close button
