# Work In Progress
<!-- Update needed: please provide the current file content with line numbers (or at least the full "Pending / In-Progress Enhancements" section) so I can precisely replace that block to mark:
1. Experiment List Aggregate Enrichment (Completed ✅)
2. Sidebar Debug Panel → Tooltip Refactor (Completed ✅)
and adjust the remaining planned items. The required edit format demands exact old_text matching (including spacing), which I cannot guarantee without fresh context. -->
## Current Status (February 2025)
### Experiment Designer Redesign - COMPLETE ✅
### Experiment Designer Redesign - COMPLETE ✅ (Phase 1)
Initial redesign delivered per `docs/experiment-designer-redesign.md`. Continuing iterative UX/scale refinement (Phase 2).
The experiment designer has been completely redesigned and implemented according to the specification in `docs/experiment-designer-redesign.md`. This represents a major architectural advancement with enterprise-grade reliability and modern UX patterns.
> Added (Pending Fixes Note): Current drag interaction in Action Library initiates panel scroll instead of producing a proper drag overlay; action items cannot yet be dropped into steps in the new virtualized workspace. Step and action reordering (drag-based) are still outstanding requirements. Action pane collapse toggle was removed (overlapped breadcrumbs). Category filters must enforce either:
> - ALL categories selected, or
> - Exactly ONE category selected
> (No ambiguous multi-partial subset state in the revamped slim panel.)
#### **Implementation Status**
#### **Implementation Status (Phase 1 Recap)**
**✅ Core Infrastructure Complete:**
- Zustand state management with comprehensive actions and selectors
- Deterministic SHA-256 hashing with incremental computation
- Type-safe validation system (structural, parameter, semantic, execution)
- Type-safe validation (structural, parameter, semantic, execution)
- Plugin drift detection with action signature tracking
- Export/import with JSON integrity bundles
- Export/import integrity bundles
**✅ UI Components Complete:**
- `DesignerShell` - Main orchestration component with tabbed layout
- `ActionLibrary` - Categorized drag-drop palette with search and filtering
- `StepFlow` - Hierarchical step/action management with @dnd-kit integration
- `PropertiesPanel` - Context-sensitive editing with enhanced parameter controls
- `ValidationPanel` - Issue filtering and navigation with severity indicators
- `DependencyInspector` - Plugin health monitoring and drift visualization
- `SaveBar` - Version control, auto-save, and export functionality
**✅ UI Components (Initial Generation):**
- `DesignerShell` (initial orchestration now superseded by `DesignerRoot`)
- `ActionLibrary` (v1 palette)
- `StepFlow` (legacy list)
- `PropertiesPanel`, `ValidationPanel`, `DependencyInspector`
- `SaveBar`
**✅ Advanced Features Complete:**
- Enhanced parameter controls (sliders, switches, type-safe inputs)
- Real-time validation with live issue detection
- Incremental hashing for performance optimization
- Plugin signature drift monitoring
- Conflict detection for concurrent editing
- Comprehensive error handling and accessibility compliance
**Phase 2 Overhaul Components (In Progress / Added):**
- `DesignerRoot` (panel + status bar orchestration)
- `PanelsContainer` (resizable/collapsible left/right)
- `BottomStatusBar` (hash / drift / unsaved quick actions)
- `ActionLibraryPanel` (slim, single-column, favorites, density, search)
- `FlowWorkspace` (virtualized step list replacing `StepFlow` for large scale)
- `InspectorPanel` (tabbed: properties / issues / dependencies)
#### **Technical Achievements**
### Recent Updates (Latest Iteration)
- **100% TypeScript** with strict type safety throughout
- **Zero TypeScript errors** - All compilation issues resolved
- **Production-ready** with comprehensive error handling
- **Accessible design** meeting WCAG 2.1 AA standards
- **Performance optimized** with incremental computation
- **Enterprise patterns** with consistent UI/UX standards
**Action Library Slim Refactor**
- Constrained width (max 240px) with internal vertical scroll
- Single-column tall tiles; star (favorite) moved top-right
- Multi-line name wrapping; description line-clamped (3 lines)
- Stacked control layout (search → categories → compact buttons)
- Eliminated horizontal scroll-on-drag issue (prevented unintended X scroll)
- Removed responsive two-column to preserve predictable drag targets
#### **Migration Status**
**Scroll / Drag Fixes**
- Explicit `overflow-y-auto overflow-x-hidden` on action list container
- Prevented accidental horizontal scroll on drag start
- Ensured tiles use minimal horizontal density to preserve central workspace
- ✅ New `DesignerShell` integrated into routing (`/experiments/[id]/designer`)
- ✅ Step addition functionality fully working
- ✅ JSX structure issues resolved
- ✅ Type-only imports properly configured
- ✅ Action Library core actions loading fixed (events category added)
- ✅ Debugging infrastructure added for plugin action tracking
- ✅ ActionLibrary reactivity fix implemented (React updates on registry changes)
- ⏳ Legacy `BlockDesigner` removal pending final validation
**Flow Pane Overhaul**
- Introduced `FlowWorkspace` virtualized list:
- Variable-height virtualization (dynamic measurement with ResizeObserver)
- Inline step rename (Enter / Escape / blur commit)
- Collapsible steps with action chips
- Insert “Below” & “Step Above” affordances
- Droppable targets registered per step (`step-<id>`)
- Quick action placeholder insertion button
- Legacy `FlowListView` retained temporarily for fallback (to be removed)
- Step & action selection preserved (integrates with existing store)
- Drag-end adaptation for action insertion works with new virtualization
### Next Immediate Tasks
**Panel Layout & Status**
- `PanelsContainer` persists widths; action panel now narrower by design
- Status bar provides unified save / export / validate with state badges
1.**Step Addition Fixed** - JSX structure and import issues resolved, functionality restored
2.**Action Library Debugging** - Added comprehensive debugging for core/plugin action loading
3.**Plugin Action Reactivity** - Fixed React component updates when plugin actions load
4. **Complete Legacy Cleanup** - Remove deprecated `BlockDesigner` after functionality verification
5. **Code Quality Improvements** - Address remaining lint warnings for production readiness
6. **Backend Integration** - Implement validation API endpoint for server-side validation
7. **Conflict Resolution UI** - Add modal for handling concurrent editing conflicts
8. **Plugin Reconciliation** - Implement drift reconciliation workflows
### Migration Status
### Current Architecture Summary
| Legacy Element | Status | Notes |
| -------------- | ------ | ----- |
| DesignerShell | Pending removal | Superseded by DesignerRoot |
| StepFlow | Being phased out | Kept until FlowWorkspace parity (reorder/drag) |
| BlockDesigner | Pending deletion | Await final confirmation |
| SaveBar | Functions; some controls now redundant with status bar (consolidation planned) |
The redesigned experiment designer follows a modern, modular architecture:
### Upcoming (Phase 2 Roadmap)
```
DesignerShell (Main Orchestration)
├── ActionLibrary (Left Panel)
├── Category Tabs (Wizard, Robot, Control, Observe)
├── Search/Filter Controls
│ └── Draggable Action Items
├── StepFlow (Center Panel)
├── Sortable Step Cards
├── Droppable Action Zones
└── Inline Action Management
└── Properties Tabs (Right Panel)
├── Properties (Step/Action Editing)
├── Issues (Validation Panel)
└── Dependencies (Plugin Inspector)
```
1. Step Reordering in `FlowWorkspace` (drag handle integration)
2. Keyboard navigation:
- Arrow up/down step traversal
- Enter rename / Escape cancel
- Shift+N insert below
3. Multi-select & bulk delete (steps + actions)
4. Command Palette (⌘K):
- Insert action by fuzzy search
- Jump to step/action
- Trigger validate / export / save
5. Graph / Branch View (React Flow selective mount)
6. Drift reconciliation modal (signature diff + adopt / ignore)
7. Auto-save throttle controls (status bar menu)
8. Server-side validation / compile endpoint integration (tRPC mutation)
9. Conflict resolution modal (hash drift vs persisted)
10. Removal of legacy `StepFlow` & associated CSS once feature parity reached
11. Optimized action chip virtualization for steps with high action counts
12. Inline parameter quick-edit popovers (for simple scalar params)
### State Management Architecture
### Adjusted Immediate Tasks
```
Zustand Store (useDesignerStore)
├── Core State (steps, selection, dirty tracking)
├── Hashing (incremental computation, integrity)
├── Validation (issue tracking, severity filtering)
├── Drift Detection (signature tracking, reconciliation)
└── Save Workflow (conflict handling, versioning)
```
### Quality Metrics
- **Code Coverage**: 100% TypeScript type safety

### Known Issues
Current (post-overhaul):
- Dragging an action from the Action Library currently causes the list to scroll (drag overlay not isolated); drop into steps intermittently fails
- Step reordering not yet implemented in `FlowWorkspace` (parity gap with legacy StepFlow)
- Action reordering within a step not yet supported in `FlowWorkspace`
- Action chips may overflow visually for extremely large action counts in one step (virtualization of actions not yet applied)
- Quick Action button inserts placeholder “control” action (needs proper action selection / palette)
- No keyboard shortcuts integrated for new workspace yet
- Legacy components still present (technical debt until removal)
- Drag hover feedback minimal (no highlight state on step while hovering)
- No diff UI for drifted action signatures (placeholder toasts only)
- Category filter logic needs enforcement: either all categories selected OR exactly one (current multi-select subset state will be removed)
- Left action pane collapse button removed (was overlapping breadcrumbs); needs optional alternative placement if reintroduced
### Technical Notes
Virtualization Approach:
- Maintains per-step dynamic height map (ResizeObserver)
- Simple windowing (top/height + overscan) adequate for current scale
- Future performance: batch measurement and optional fixed-row mode fallback
Action Insertion:
- Drag from library → step droppable ID
- Inline Quick Action path uses placeholder until palette arrives
State Integrity:
- Virtualization purely visual; canonical order & mutation operations remain in store (no duplication)
### Documentation To Update (Queued)
- `implementation-details.md`: Add virtualization strategy & PanelsContainer architecture
- `experiment-designer-redesign.md`: Append Phase 2 evolution section
- `quick-reference.md`: New shortcuts & panel layout (pending keyboard work)
- Remove references to obsolete `DesignerShell` post-cleanup
### Next Execution Batch (Planned)
1. Implement step drag reordering (update store + optimistic hash recompute)
2. Keyboard navigation & shortcuts foundation
3. Command palette scaffold (providers + fuzzy index)
4. Legacy component removal & doc synchronization
1.**Step Addition**: Fixed - JSX structure and type imports resolved
2.**Core Action Loading**: Fixed - Added missing "events" category to ActionRegistry
3.**Plugin Action Display**: Fixed - ActionLibrary now reactively updates when plugins load
