- Add createdAt timestamp to WorkflowEdgeData interface
- Store createdAt on edge creation in onConnect and addEdgeWithType
- Add getImageSequenceNumber helper to EdgeToolbar
- Display "Image N" label for image connections with 2+ edges to same target
- Sequence numbers based on createdAt for stable ordering
- Single connections and text connections show no numbering
- Create comprehensive test suite for extractSubgraph function
- Test cases cover: no selection, select all, single node, connected pairs,
subset selection, type breakdown, disconnected nodes, multi-handle scenarios
- All 8 tests failing with "Not implemented" error (RED phase)

Rewrite /api/chat route to accept workflow context from client and use
AI SDK tool calling for multi-modal agent routing.
Changes:
- Accept optional workflowState (nodes/edges) in request body
- Build workflow context using buildWorkflowContext from contextBuilder
- Generate context-aware system prompt using buildEditSystemPrompt
- Create chat tools (answerQuestion, createWorkflow, editWorkflow) with
current node IDs for validation
- Configure streamText with tools, toolChoice: 'auto', and stopWhen for
multi-step reasoning (up to 3 steps)
- Stream results back via toUIMessageStreamResponse for useChat hook
compatibility
LLM now automatically routes to the correct tool based on user intent.
Tool results stream back to client for application in Plan 03.

Create editOperations.ts with EditOperation type union covering all 5 operation types (addNode, removeNode, updateNode, addEdge, removeEdge). Implement applyEditOperations function with batched immutable updates, proper ID generation, and validation with skip tracking. Add narrateOperations function for human-readable summaries.
Create contextBuilder.ts with WorkflowContext interface and buildWorkflowContext function that strips base64 data, history arrays, and internal state. Add formatContextForPrompt function for system prompt injection.
Both modules are pure TypeScript with no UI or API dependencies.

Tasks 1 & 2: Complete AI workflow revert feature
Changes:
- WorkflowCanvas: Call captureSnapshot() before AI loadWorkflow
- Header: Add "Revert AI Changes" button with confirmation dialog
- Button visible only when previousWorkflowSnapshot exists
- Amber styling to distinguish safety feature from destructive actions
Snapshot capture ONLY in AI generation path (not file loads/templates).
Button auto-hides after revert or 3 manual changes (store handles this).

These planning phase documents are local development artifacts
that don't need to be shared in the repo. They remain in .gitignore.

- Image data flow through node chains (imageInput, annotation, nanoBanana)
- Text data flow through node chains (prompt, llmGenerate)
- Dynamic inputs from schema-mapped connections
- State updates during execution (status, outputImage)
- Mixed image and text data flow
Phase 20: Integration Tests
- 2 plans created
- 6 total tasks defined
- Tests cover getConnectedInputs, validateWorkflow, topological sort,
data flow, error handling, and connection validation
- Ready for execution

Phase 19 complete. All types now organized into 7 domain files:
annotation, nodes, providers, models, workflow, api, quickstart.
index.ts is a pure re-export hub.

- Remove Task 1 (part ordering fix) - no longer needed
- Phase now focused on unifying MD5 hashing for deduplication
- 1 task remaining

Phase 21: Fix Image Input & Deduplication Issues
- 1 plan created
- 2 tasks + 1 checkpoint defined
- Ready for execution
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Fix isImageInput() to use word-boundary checks instead of substring
matching, preventing num_images from being misclassified as image input
- Fix stale node data in workflow execution by getting fresh data from
store instead of using captured array references
- Add missing parameters to regenerateNode request bodies for both
nanoBanana and generateVideo nodes
- Update fal.ai schema fetch to use Model Search API endpoint
