Phase 14 Plan 01: Fix Drag-Connect Node Creation Bugs Summary

Placeholder handles ensure connections persist when selecting models that don't use all input types

Performance

• Duration: 12 min
• Started: 2026-01-12T10:11:43Z
• Completed: 2026-01-12T10:23:00Z
• Tasks: 3
• Files modified: 4

Accomplishments

• Always render "image" and "text" handles even when model schema doesn't include them
• Placeholder handles (dimmed at 30% opacity) preserve connections for models that don't use that input type
• Normalized dynamic handle IDs to use standard values ("image", "text") instead of schema-specific names
• Updated connection validation to return normalized handle IDs when finding compatible targets
• Added handle-to-schema mapping in execution to preserve API parameter compatibility

Task Commits

Each task was committed atomically:

1. Task 1: Normalize handle IDs + placeholder handles - 7548e5a (fix)
2. Task 2: Update connection validation - 714b60b (fix)
3. Task 3: Map handles to schema names in execution - 5643cb8 (feat)

Files Created/Modified

• src/components/nodes/GenerateImageNode.tsx - Placeholder handles for missing inputs, normalized IDs
• src/components/nodes/GenerateVideoNode.tsx - Same fix for video nodes
• src/components/WorkflowCanvas.tsx - findCompatibleHandle returns normalized IDs
• src/store/workflowStore.ts - getConnectedInputs builds handleToSchemaName mapping

Decisions Made

• Placeholder handles: Always render "image" and "text" handles, dimmed when model doesn't use them
• Normalized handle naming: Single input of type uses base name ("image"), multiple use indexed ("image-0", "image-1")
• Schema name preservation: Stored in data-schema-name attribute for debugging/reference
• Execution mapping: Build mapping at runtime from inputSchema rather than storing in edge data

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Handle disappearance with text-to-image models

• Found during: Testing after initial fix
• Issue: Text-to-image models (FLUX, etc.) have no image input in schema, causing image handle to disappear
• Fix: Always render placeholder handles for missing input types (dimmed at 30% opacity)
• Files modified: GenerateImageNode.tsx, GenerateVideoNode.tsx
• Verification: Build passes, handles persist through model selection

Issues Encountered

None

Next Phase Readiness

• Phase 14 complete (single plan phase)
• Milestone v1.1 complete - all 8 phases finished
• Ready for /gsd:complete-milestone
