Phase 8 Plan 01: Error Display Summary

Persistent top-right toast notifications with expandable error details, plus semi-transparent red overlays on failed generate nodes

Performance

• Duration: 14 min
• Started: 2026-01-11T23:40:10Z
• Completed: 2026-01-11T23:54:13Z
• Tasks: 4
• Files modified: 3

Accomplishments

• Toast component enhanced: moved to top-right, added persistent mode, added expandable details
• Error overlay added to GenerateImageNode showing failure state over previous output
• Error overlay added to GenerateVideoNode with same pattern
• Users can now see errors even when previous generation output exists

Task Commits

Each task was committed atomically:

1. Task 1: Update Toast component - 6625449 (feat)
2. Task 2: GenerateImageNode error overlay - 77fdea5 (feat)
3. Task 3: GenerateVideoNode error overlay - 7356fd0 (feat)
4. UAT fix: Reduce overlay opacity - ee6214d (fix)
5. UAT fix: White text for contrast - dbc0727 (fix)

Files Created/Modified

• src/components/Toast.tsx - Added persistent mode, details expansion, top-right positioning
• src/components/nodes/GenerateImageNode.tsx - Added error overlay, toast trigger on error
• src/components/nodes/GenerateVideoNode.tsx - Added error overlay, toast trigger on error

Decisions Made

• Moved toast from bottom-center to top-right for better visibility
• Error overlay uses 40% opacity (reduced from 70% during UAT)
• White text on red overlay for better contrast (changed during UAT)
• Toast requires manual dismiss for errors (persistent mode)

Deviations from Plan

UAT Adjustments

1. Reduced overlay opacity

• Found during: UAT verification
• Issue: 70% opacity too dark, obscured previous output
• Fix: Reduced to 40% opacity
• Committed in: ee6214d

2. Changed text color for contrast

• Found during: UAT verification
• Issue: Red text on red overlay hard to read
• Fix: Changed to white text
• Committed in: dbc0727

Total deviations: 2 UAT fixes (visual adjustments) Impact on plan: Minor visual refinements based on user feedback

Issues Encountered

None - all tasks completed as planned with minor visual adjustments during UAT.

Issues Logged

• ISS-002: Multi-image inputs not mapped correctly for fal.ai models (discovered during UAT, unrelated to this phase)

Next Phase Readiness

• Error display complete, ready for Phase 9 (Video History)
• No blockers
