# Work in Progress

## Recent Changes Summary (February 2025)

### Experiment Designer Iteration (February 2025)

#### **Current Focus: Experiment Designer Redesign (Hashing / Drift / Action Library / Properties / DnD / Save & Export)**
**Status**: In active iteration (not stable)

The experiment designer has been refactored into modular components (registry + library + flow + properties panel). Active iteration now targets validation drift visibility, richer parameter controls, and continued provenance/compilation integrity.

**Implemented (baseline):**
- Step-first container model (steps hold ordered actions) (stable)
- Drag-and-drop of actions into steps and reordering within steps (stable)
- Conversion utility to DB step/action structures (provenance & execution metadata flattening) (stable)
- Plugin action loading with namespaced IDs (pluginId.actionId) and provenance retention (stable)
- Execution compilation pipeline (deterministic graph + integrity hash) integrated in update mutation (stable)

**UI State (updated):**
- Compact spacing (h-6/7 inputs) and category coloring
- Dark mode variants applied (will audit accessibility)
- Category color system (may refine semantic tokens; now reused across extracted components)
- Step containers with colored left borders for type (moved into `StepFlow`)
- Drag overlays + hover states (keyboard reordering & provenance badge a11y still pending)

**Interaction Features (present / modularized):**
- Multi-level drag & drop (steps + actions) via `StepFlow`
- Direct action selection for inline parameter editing (now inside `PropertiesPanel`)
- Action tooltip (plugin/source details; provenance badges present; enrichment still planned)
- Drop zone highlighting
- Pointer sensor activation threshold (mobile/touch review pending)

**Plugin Integration (status):**
- Registry loads core + study plugin actions (version stored; pin drift resolution still pending; designer now guarantees installed study plugin actions appear once experiment + study resolved)
- Fallback actions present (unchanged)
- Param schema → UI field mapping (primitive only; now enhanced for boolean + ranged number)
- Provenance & execution metadata embedded in action instances (server persists) (stable)
- Structured error surfaces for plugin load/validation failures still TODO

**Technical Notes (updated):**
- Types expanded: provenance, execution descriptors, integrity hashing structures (stable)
- Acceptable performance; profiling after slider & drift logic integration still pending
- Accessibility review pending (keyboard reorder, focus indicators, slider a11y labels)
- Monolith split complete: `ActionRegistry.ts`, `ActionLibrary.tsx`, `StepFlow.tsx`, `PropertiesPanel.tsx`
- Need unit tests for registry + conversion + compiler + drift serializer; none present

**Key Files (current iteration - post modularization):**
- `~/components/experiments/designer/BlockDesigner.tsx` - Orchestrator (state, validation, drift)
- `~/components/experiments/designer/ActionRegistry.ts` - Registry (core + plugin + fallback)
- `~/components/experiments/designer/ActionLibrary.tsx` - Categorized draggables
- `~/components/experiments/designer/StepFlow.tsx` - Sortable steps & actions

- `~/components/experiments/designer/PropertiesPanel.tsx` - Parameter & metadata editor
**Current State Summary:**
Functional baseline with modular extraction complete. Parameter UI upgraded (boolean → Switch, ranged number → Slider). Hash drift indicator implemented (Validated / Drift / Unvalidated). Still pending: enum grouping polish, keyboard DnD accessibility, version pin drift resolution, structured plugin load error surfaces.

### Experiment Designer Redesign Implementation (in progress)

#### **Status Snapshot**
Simplified and unified the seed scripts to load all plugins (core and robot) through the same repository sync mechanism.

**Seed Script Consolidation:**
- **Before**: 5 separate seed scripts (`seed.ts`, `seed-dev.ts`, `seed-simple.ts`, `seed-plugins.ts`, `seed-core-blocks.ts`)
- **After**: Single `seed-dev.ts` script with integrated repository sync
- **Benefits**: Consistent plugin loading, easier maintenance, real repository testing

**Core Repository Integration:**
- Core blocks now loaded from `http://localhost:3000/hristudio-core` during development
- Same repository sync logic as robot plugins from `https://repo.hristudio.com`
- Eliminates hardcoded core blocks - everything comes from repositories
- Local core repository served from `public/hristudio-core/` directory

**Simplified Setup Process:**
```bash
docker compose up -d
bun db:push  
bun db:seed  # Single command loads everything
```

**Repository Sync Integration:**
- Core system blocks loaded as single plugin with 4 block groups (27 total blocks)
- Robot plugins loaded individually (TurtleBot3 Burger/Waffle, NAO) 
- All repositories use same sync validation and error handling
- Proper metadata storage with repository references

**Package.json Cleanup:**
- Removed `db:seed:simple`, `db:seed:plugins`, `db:seed:core-blocks`, `db:seed:full`
- Single `db:seed` command for all seeding needs
- Simplified development workflow with fewer script options

---

- Spec Document: `docs/experiment-designer-redesign.md` (completed)
- Hashing Model: Implementing (canonical + incremental planned)
- State Store: Planned (Zustand-based)
- Action Library: Pending rebuild (categorization + search + drift markers)
- Step Flow: Existing structure to be replaced with new DnD + keyboard support
- Properties Panel: To adopt dynamic ParameterFieldFactory (Switch / Slider / etc.)
- Validation Layer: Rule set drafting (structural + param + plugin)
- Drift Detection: Planned (design vs last validated hash + plugin signature drift)
- Save / Versioning: Pending (auto-save + manual + conflict detection)
- Export / Import: Export bundle utility planned
- Removal of legacy naming (“enhanced” / transitional) in progress
- Docs Cross-linking: Partially updated

#### **Next Milestones**
Fixed and implemented full repository synchronization for dynamic plugin loading from remote repositories.

**Core Fixes:**
- **Repository Sync Implementation**: Fixed TODO placeholder in `admin.repositories.sync` API with complete synchronization logic

---

### Complete Experiment Designer Redesign

#### **Background**
The experiment designer was completely redesigned to integrate seamlessly with the HRIStudio application's existing design system and component patterns. The original designer felt out of place and used inconsistent styling.

#### **Key Changes Made**

##### **1. Layout System Overhaul**
- **Before**: Custom resizable panels with full-page layout
- **After**: Standard PageHeader + Card-based grid system
- **Components Used**: 
  - `PageHeader` with title, description, and action buttons
  - `Card`, `CardHeader`, `CardTitle`, `CardContent` for all sections
  - 12-column grid layout (3-6-3 distribution)

##### **2. Visual Integration**
- **Header**: Now uses unified `PageHeader` component with proper actions
- **Action Buttons**: Replaced custom buttons with `ActionButton` components
- **Status Indicators**: Badges integrated into header actions area
- **Icons**: Each card section has relevant icons (Palette, Play, Settings)

##### **3. Component Consistency**
- **Height Standards**: All inputs use `h-8` sizing to match system
- **Spacing**: Uses standard `space-y-6` and consistent card padding
- **Typography**: Proper text hierarchy matching other pages
- **Empty States**: Compact and informative design

##### **4. Technical Improvements**
- **Simplified Drag & Drop**: Removed complex resizable panel logic
- **Better Collision Detection**: Updated for grid layout structure
- **Function Order Fix**: Resolved initialization errors with helper functions
- **Clean Code**: Removed unused imports, fixed TypeScript warnings

#### **Code Structure Changes**

##### **Layout Before**:
```jsx
<DndContext>
  <div className="flex h-full flex-col">
    <div className="bg-card flex items-center justify-between border-b">
      {/* Custom header */}
    </div>
    <ResizablePanelGroup>
      <ResizablePanel>{/* Palette */}</ResizablePanel>
      <ResizablePanel>{/* Canvas */}</ResizablePanel>
      <ResizablePanel>{/* Properties */}</ResizablePanel>
    </ResizablePanelGroup>
  </div>
</DndContext>
```

##### **Layout After**:
```jsx
<DndContext>
  <div className="space-y-6">
    <PageHeader 
      title={design.name}
      description="Design your experiment protocol using visual blocks"
      icon={Palette}
      actions={/* Save, Export, Badges */}
    />
    <div className="grid grid-cols-12 gap-6">
      <div className="col-span-3">
        <Card>{/* Block Library */}</Card>
      </div>
      <div className="col-span-6">
        <Card>{/* Experiment Flow */}</Card>
      </div>
      <div className="col-span-3">
        <Card>{/* Properties */}</Card>
      </div>
    </div>
  </div>
</DndContext>
```

#### **Files Modified**
- `src/components/experiments/designer/BlockDesigner.tsx` - Current iterative version
- `src/components/ui/data-table.tsx` - Fixed control heights
- `src/components/experiments/experiments-data-table.tsx` - Fixed select styling
- `src/components/participants/participants-data-table.tsx` - Fixed select styling
- `src/components/studies/studies-data-table.tsx` - Fixed select styling
- `src/components/trials/trials-data-table.tsx` - Fixed select styling

---

### Data Table Controls Standardization

#### **Problem**
Data table controls (search input, filter selects, columns dropdown) had inconsistent heights and styling, making the interface look unpolished.

#### **Solution**
- **Search Input**: Already had `h-8` - ✅
- **Filter Selects**: Added `h-8` to all `SelectTrigger` components
- **Columns Dropdown**: Already had proper Button styling - ✅

#### **Tables Fixed**
- Experiments data table
- Participants data table  
- Studies data table (2 selects)
- Trials data table

---

### System Theme Enhancements

#### **Background**
The overall system theme was too monochromatic with insufficient color personality.

#### **Improvements Made**

##### **Color Palette Enhancement**
- **Primary Colors**: More vibrant blue (`oklch(0.55 0.08 240)`) instead of grayscale
- **Background Warmth**: Added subtle warm undertones to light mode
- **Sidebar Blue Tint**: Maintained subtle blue character as requested
- **Chart Colors**: Proper color progression (blue → teal → green → yellow → orange)

##### **Light Mode**:
```css
--primary: oklch(0.55 0.08 240);        /* Vibrant blue */
--background: oklch(0.98 0.005 60);     /* Warm off-white */
--card: oklch(0.995 0.001 60);          /* Subtle layering */
--muted: oklch(0.95 0.008 240);         /* Slight blue tint */
```

##### **Dark Mode**:
```css
--primary: oklch(0.65 0.1 240);         /* Brighter blue */
--background: oklch(0.12 0.008 250);    /* Soft dark with blue undertone */
--card: oklch(0.18 0.008 250);          /* Proper contrast layers */
--muted: oklch(0.22 0.01 250);          /* Subtle blue-gray */
```

#### **Results**
- Much more personality and visual appeal
- Better color hierarchy and element distinction
- Professional appearance maintained
- Excellent accessibility and contrast maintained

### Breadcrumb Navigation Fixes

#### **Problems Identified**
1. **Study-scoped pages** linking to wrong routes (missing context)
2. **Form breadcrumbs** linking to non-existent entities during creation
3. **Inconsistent study context** across different data tables

#### **Solutions Implemented**

##### **Study Context Awareness**
- **ExperimentsDataTable**: `Dashboard → Studies → [Study Name] → Experiments`
- **ParticipantsDataTable**: `Dashboard → Studies → [Study Name] → Participants`  
- **TrialsDataTable**: `Dashboard → Studies → [Study Name] → Trials`

##### **Form Breadcrumbs Fixed**
- **ExperimentForm**: Uses study context when available, falls back to global
- **ParticipantForm**: Links to study-scoped participants when in study context
- **TrialForm**: Links to study-scoped trials when available

##### **Smart Link Logic**
- ✅ **With `href`**: Renders as clickable `<BreadcrumbLink>`
- ✅ **Without `href`**: Renders as non-clickable `<BreadcrumbPage>`
- ✅ **Conditional availability**: Only provides `href` when target exists

---

### Technical Debt Cleanup

#### **Block Designer Fixes**
1. **Nested Block Drag & Drop**: Added proper `SortableContext` for child blocks
2. **Collision Detection**: Enhanced for better nested block handling  
3. **Helper Functions**: Fixed initialization order (`findBlockById`, `removeBlockFromStructure`)
4. **Background Colors**: Matched page theme properly

#### **Permission System**
- **Added Administrator Bypass**: System admins can now edit any experiment
- **Study Access Check**: Enhanced to check both study membership and system roles

#### **API Enhancement**
- **Visual Design Storage**: Added `visualDesign` field to experiments update API
- **Database Integration**: Proper saving/loading of block designs

---

### Current Status (Deprecated Section - To Be Rewritten)

#### **Completed**
- (Remove) Designer not yet in a stable/complete state
- All data table control styling standardized
- System theme enhanced with better colors
- Breadcrumb navigation completely fixed
- Technical debt resolved

#### **Production Ready**
- TypeScript surface improving; more types to add for provenance/execution
- Consistent styling throughout application
- Proper error handling and user feedback
- Excellent dark mode support
- Mobile/tablet friendly drag and drop

#### **Improvements Achieved**
- Visual consistency improved; still refactoring designer component size
- **User Experience**: Significant improvement in navigation and usability
- **Code Quality**: Clean, maintainable code with proper patterns
- **Performance**: Optimized drag and drop with better collision detection
- **Accessibility**: WCAG 2.1 AA compliance maintained throughout

### Core Block System Implementation (February 2024) (archived)

**Complete documentation available in [`docs/core-blocks-system.md`](core-blocks-system.md)**

#### **Repository-Based Core Blocks**
Complete overhaul of the experiment designer to use plugin-based architecture for all blocks.

**Architecture Change:**
- **Before**: Hardcoded core blocks in `BlockRegistry.initializeCoreBlocks()`
- **After**: Repository-based loading from `hristudio-core` plugin repository
- **Benefits**: Complete consistency, easier updates, extensible core functionality

**Core Repository Structure:**
```
hristudio-core/
├── repository.json           # Repository metadata
├── plugins/
│   ├── index.json           # Plugin index (26 total blocks)
│   ├── events.json          # Event trigger blocks (4 blocks)
│   ├── wizard-actions.json  # Wizard action blocks (6 blocks)
│   ├── control-flow.json    # Control flow blocks (8 blocks)
│   └── observation.json     # Observation blocks (8 blocks)
└── assets/                  # Repository assets
```

**Block Categories Implemented:**

##### **Event Triggers (4 blocks)**
- `when_trial_starts` - Trial initialization trigger
- `when_participant_speaks` - Speech detection with duration threshold
- `when_timer_expires` - Time-based triggers with custom delays
- `when_key_pressed` - Wizard keyboard shortcuts (space, enter, numbers)

##### **Wizard Actions (6 blocks)**
- `wizard_say` - Speech with tone guidance (neutral, friendly, encouraging)
- `wizard_gesture` - Physical gestures (wave, point, nod, applaud) with directions
- `wizard_show_object` - Object presentation with action types
- `wizard_record_note` - Observation recording with categorization
- `wizard_wait_for_response` - Response waiting with timeout and prompts
- `wizard_rate_interaction` - Subjective rating scales (1-5, 1-7, 1-10, custom)

##### **Control Flow (8 blocks)**
- `wait` - Pause execution with optional countdown display
- `repeat` - Loop execution with delay between iterations
- `if_condition` - Conditional logic with multiple condition types
- `parallel` - Simultaneous execution with timeout controls
- `sequence` - Sequential execution with error handling
- `random_choice` - Weighted random path selection
- `try_catch` - Error handling with retry mechanisms
- `break` - Exit controls for loops, sequences, trials

##### **Observation & Sensing (8 blocks)**
- `observe_behavior` - Behavioral coding with standardized scales
- `measure_response_time` - Stimulus-response timing measurement
- `count_events` - Event frequency tracking with auto-detection
- `record_audio` - Audio capture with quality settings and transcription
- `capture_video` - Multi-camera video recording with resolution control
- `log_event` - Timestamped event logging with severity levels
- `survey_question` - In-trial questionnaires with response validation
- `physiological_measure` - Sensor data collection with sampling rates

**Technical Implementation:**
- **Dynamic Loading**: Core blocks loaded from `/public/hristudio-core/plugins/`
- **Fallback System**: Minimal core blocks if repository loading fails
- **Validation**: Complete JSON schema validation with color/category consistency
- **Async Initialization**: Non-blocking core block loading on component mount
- **Type Safety**: Full TypeScript support with proper block definitions

**Files Created/Modified:**
- `hristudio-core/` - Complete core blocks repository
- `public/hristudio-core/` - Publicly served core blocks
- Enhanced `BlockRegistry.loadCoreBlocks()` method
- Repository validation script with ES modules support
- Comprehensive documentation and block schemas

**Benefits Achieved:**
- **Consistency**: All blocks now follow the same plugin architecture
- **Extensibility**: Easy to add new core blocks without code changes
- **Version Control**: Core blocks can be versioned and updated independently
- **Modularity**: Clean separation between core functionality and robot plugins
- **Maintainability**: Centralized block definitions with validation
