+# Phase 22-01: Generate Node Dynamic Input Tests Summary
+
+**Extended test coverage for dynamic input handles and API parameter passthrough across generate nodes**
+
+## Performance
+
+- **Duration:** 20 min
+- **Started:** 2026-01-13T07:05:30Z
+- **Completed:** 2026-01-13T07:25:15Z
+- **Tasks:** 4 (1 skipped - already complete)
+- **Files modified:** 3
+
+## Accomplishments
+
+- Extended GenerateImageNode tests with 10 new tests for dynamic handles
+- Extended GenerateVideoNode tests with 7 new tests mirroring image node coverage
+- Added 4 API route tests verifying parameters field passthrough
+- Verified total of 180 tests passing across all affected test files
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: ModelParameters component tests** - Skipped (pre-existing coverage)
+2. **Task 2: GenerateImageNode dynamic handle tests** - `32a94bf` (test)
+3. **Task 3: GenerateVideoNode dynamic handle tests** - `6170745` (test)
+4. **Task 4: API route parameters tests** - `0f3f9e5` (test)
+
+## Files Created/Modified
+
+- `src/components/__tests__/GenerateImageNode.test.tsx` - Extended with Multiple Image Inputs, Multiple Text Inputs, Placeholder Handle Variations, Handle Ordering tests (+235 lines)
+- `src/components/__tests__/GenerateVideoNode.test.tsx` - Extended with Multiple Image Inputs, Placeholder Handles, Schema Integration tests (+160 lines)
+- `src/app/api/generate/__tests__/route.test.ts` - Extended with parameters passthrough tests for Replicate and fal.ai (+233 lines)
+
+## Decisions Made
+
+- Task 1 (ModelParameters tests) skipped - test file already existed with comprehensive coverage of all plan requirements including schema loading, parameter handling, and collapse/expand behavior
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+None - plan executed as written (with Task 1 determined to be already complete).
+
+### Deferred Enhancements
+
+None
+
+---
+
+**Total deviations:** 0 auto-fixed, 0 deferred
+**Impact on plan:** Task 1 was pre-completed; remaining 3 tasks executed as specified.
+
+## Issues Encountered
+
+None
+
+## Test Coverage Summary
+
+| Test File | Tests | Status |
+|-----------|-------|--------|
+| ModelParameters.test.tsx | 30 | Passed |
+| GenerateImageNode.test.tsx | 46 | Passed |
+| GenerateVideoNode.test.tsx | 45 | Passed |
