- **Study-Scoped Architecture**: All entity management now flows through studies (`/studies/[id]/participants`, `/studies/[id]/trials`, `/studies/[id]/analytics`)
- **Dashboard Route Fixed**: Resolved `/dashboard` 404 issue by moving from `(dashboard)` route group to explicit `/dashboard` route
- **Helpful Redirects**: Created redirect pages for moved routes with auto-redirect when study context exists
- **Custom 404 Handling**: Added dashboard-layout 404 page for broken links within dashboard area
- **Navigation Cleanup**: Updated sidebar, breadcrumbs, and all navigation references
- **Form Updates**: Fixed all entity forms (ParticipantForm, TrialForm) to use study-scoped routes
- **Component Consolidation**: Removed duplicate components (`participants-data-table.tsx`, `trials-data-table.tsx`, etc.)
**Benefits Achieved:**
- **Logical Hierarchy**: Studies → Participants/Trials/Analytics creates intuitive workflow
- **Reduced Complexity**: Eliminated confusion about where to find functionality
- **Code Reduction**: Removed significant duplicate code between global and study-scoped views
- **Better UX**: Clear navigation path through study-centric organization
- **Maintainability**: Single source of truth for each entity type
## Next Priority: WebSocket Implementation Enhancement
### WebSocket Real-Time Infrastructure - IN PROGRESS 🚧
Critical for thesis research - enable real-time trial execution and monitoring.
**Current Status:**
- ✅ Basic WebSocket hooks exist (`useWebSocket.ts`, `useTrialWebSocket.ts`)
- ✅ Trial execution engine with tRPC endpoints
-**Missing**: Real-time robot communication and status updates
-**Missing**: Live trial event broadcasting to all connected clients
-**Missing**: WebSocket server implementation for trial coordination
**Required Implementation:**
- **Robot Integration**: WebSocket connection to robot platforms (ROS2, REST APIs)
- **Event Broadcasting**: Real-time trial events to wizard, observers, and monitoring systems
- **Session Management**: Multi-client coordination for collaborative trial execution
- **Error Handling**: Robust connection recovery and fallback mechanisms
- **Security**: Proper authentication and role-based WebSocket access
**Files to Focus On:**
- `src/hooks/useWebSocket.ts` - Client-side WebSocket management
- `src/server/services/trial-execution.ts` - Trial execution engine
- WebSocket server implementation (needs creation)
- Robot plugin WebSocket adapters
## Previous Status (December 2024)
### Experiment Designer Redesign - COMPLETE ✅ (Phase 1)
Initial redesign delivered per `docs/experiment-designer-redesign.md`. Continuing iterative UX/scale refinement (Phase 2).
> 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 (Phase 1 Recap)**
**✅ Core Infrastructure Complete:**
- Zustand state management with comprehensive actions and selectors
- Deterministic SHA-256 hashing with incremental computation
- Type-safe validation (structural, parameter, semantic, execution)
- Plugin drift detection with action signature tracking
- Export/import integrity bundles
**✅ UI Components (Initial Generation):**
- `DesignerShell` (initial orchestration now superseded by `DesignerRoot`)
- `ActionLibrary` (v1 palette)
- `StepFlow` (legacy list)
- `PropertiesPanel`, `ValidationPanel`, `DependencyInspector`
- `SaveBar`
**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)
### Recent Updates (Latest Iteration)
**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
**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
**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
**Panel Layout & Status**
- `PanelsContainer` persists widths; action panel now narrower by design
- Status bar provides unified save / export / validate with state badges
### Migration Status
| Legacy Element | Status | Notes |
| -------------- | ------ | ----- |
| DesignerShell | ✅ Removed | Superseded by DesignerRoot |
| StepFlow | ✅ Removed | Superseded by FlowWorkspace |
| BlockDesigner | ✅ Removed | Superseded by DesignerRoot |
| SaveBar | ✅ Removed | Functions consolidated in BottomStatusBar |
| ActionLibrary | ✅ Removed | Superseded by ActionLibraryPanel |
| FlowListView | ✅ Removed | Superseded by FlowWorkspace |
### Upcoming (Phase 2 Roadmap)
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 components completed (BlockDesigner, DesignerShell, StepFlow, ActionLibrary, SaveBar, FlowListView)
11. Optimized action chip virtualization for steps with high action counts
12. Inline parameter quick-edit popovers (for simple scalar params)
### Adjusted Immediate Tasks
| # | Task | Status |
| - | ---- | ------ |
| 1 | Slim action pane + scroll fix | ✅ Complete |
| 2 | Introduce virtualized FlowWorkspace | ✅ Initial implementation |
| 3 | Migrate page to `DesignerRoot` | ✅ Complete |
| 4 | Hook drag-drop into new workspace | ✅ Complete |
| 5 | Step reorder (drag) | ⏳ Pending |
| 6 | Command palette | ⏳ Pending |
| 7 | Remove legacy `StepFlow` & `FlowListView` | ⏳ After reorder |
| 8 | Graph view toggle | ⏳ Planned |
| 9 | Drift reconciliation UX | ⏳ Planned |
| 10 | Conflict resolution modal | ⏳ Planned |
### 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
4.**Legacy Cleanup**: All legacy designer components removed
5. **Code Quality**: Some lint warnings remain (non-blocking for functionality)
6. **Validation API**: Server-side validation endpoint needs implementation
7. **Error Boundaries**: Need enhanced error recovery for plugin failures

- **Improved Workflow**: Optimized information architecture for trial execution
- **Code Reuse**: Minimal duplication with maximum functionality
### Unified Study Selection System (Completed)
The platform previously had two parallel mechanisms for tracking the active study (`useActiveStudy` and `study-context`). This caused inconsistent filtering across root entity pages (experiments, participants, trials).
**What Changed**
- Removed legacy hook: `useActiveStudy` (and its localStorage key).
- Unified on: `study-context` (key: `hristudio-selected-study`).
- Added helper hook: `useSelectedStudyDetails` for enriched metadata (name, counts, role).
- Updated all studyscoped root pages and tables:
- `/experiments` → now strictly filtered server-side via `experiments.list(studyId)`
- `/studies/[id]/participants` + `/studies/[id]/trials` → set `selectedStudyId` from route param
- `ExperimentsTable`, `ParticipantsTable`, `TrialsTable` → consume `selectedStudyId`
- Normalized `TrialsTable` mapping to the actual `trials.list` payload (removed unsupported fields like wizard/session aggregates).
- Breadcrumbs (participants/trials pages) now derive the study name via `useSelectedStudyDetails`.
**Benefits**
- Single source of truth for active study
- Elimination of state drift between pages
- Reduced query invalidation complexity
- Clearer contributor mental model
**FollowUp (Optional)**
1. Introduce a global Study Switcher component consuming `useSelectedStudyDetails`.
2. Preload study metadata via a server component wrapper to avoid initial loading flashes.
3. Extend `trials.list` (if needed) with lightweight aggregates (events/media counts) using a summarized join/CTE.
4. Consolidate repeated breadcrumb patterns into a shared utility.
This unification completes the study selection refactor and stabilizes perstudy scoping across the application.
### Trial System Production Status
**Current Capabilities:**

- Diagnostics preserved without clutter ✅
- Dev-only visibility preserves production cleanliness ✅
#### 3. Study Switcher Consolidation - COMPLETE ✅
Consolidated study selection & metadata:
- Unified context hydration (cookie + localStorage) ✅
- Single study list source (studies.list) ✅
- Selected study metadata via `useSelectedStudyDetails`
- Mutations & invalidations centralized in existing management hook ✅
Remaining: optional future reduction of legacy helper surface.
