+## Trials System Implementation - COMPLETE ✅ (Panel-Based Architecture)
+
+### Current Status (December 2024)
+
+The trials system implementation is now **complete and functional** with a robust execution engine, real-time WebSocket integration, and panel-based wizard interface matching the experiment designer architecture.
+
+#### **✅ Completed Implementation (Panel-Based Architecture):**

+
+**Phase 2: Core Trial Execution Engine (COMPLETE)**
+- ✅ **TrialExecutionEngine service** (`src/server/services/trial-execution.ts`)
+  - Comprehensive step-by-step execution logic
+  - Action validation and timeout handling
+  - Robot action dispatch through plugin system
+  - Wizard action coordination and completion tracking
+  - Variable context management and condition evaluation
+- ✅ **Execution Context Management**
+  - Trial initialization and state tracking
+  - Step progression with validation
+  - Action execution with success/failure handling
+  - Real-time status updates and event logging
+- ✅ **Database Integration**
+  - Automatic `trial_events` logging for all execution activities
+  - Proper trial status management (scheduled → in_progress → completed/aborted)
+  - Duration tracking and completion timestamps
+
+**Database & API Layer:**
+- Complete `trials` table with proper relationships and status management
+- `trial_events` table for comprehensive data capture and audit trail
+- **Enhanced tRPC router** with execution procedures:
+  - `executeCurrentStep` - Execute current step in trial protocol
+  - `advanceToNextStep` - Advance to next step with validation
+  - `getExecutionStatus` - Real-time execution context
+  - `getCurrentStep` - Current step definition with actions
+  - `completeWizardAction` - Mark wizard actions as completed
+- Proper role-based access control and study scoping
+
+**Real-time WebSocket System:**
+- Edge runtime WebSocket server at `/api/websocket/route.ts`
+- Per-trial rooms with event broadcasting and state management
+- Typed client hooks (`useWebSocket`, `useTrialWebSocket`)
+- Trial state synchronization across connected clients
+- Heartbeat and reconnection handling with exponential backoff
+
+**Page Structure & Navigation:**
+- `/trials` - Main list page with status filtering and study scoping ✅
+- `/trials/[trialId]` - Detailed trial view with metadata and actions ✅
+- `/trials/[trialId]/wizard` - Live execution interface with execution engine ✅
+- `/trials/[trialId]/start` - Pre-flight scheduling and preparation ✅
+- `/trials/[trialId]/analysis` - Post-trial analysis dashboard ✅
+- `/trials/[trialId]/edit` - Trial configuration editing ✅
+
+**Enhanced Wizard Interface:**
+- `WizardInterface` - Main real-time control interface with execution engine integration
+- **New `ExecutionStepDisplay`** - Advanced step visualization with:
+  - Current step progress and action breakdown
+  - Wizard instruction display for required actions
+  - Action completion tracking and validation
+  - Parameter display and condition evaluation
+  - Execution variable monitoring
+- Component suite: `ActionControls`, `ParticipantInfo`, `RobotStatus`, `TrialProgress`
+- Real-time execution status polling and WebSocket event integration
+
+#### **🎯 Execution Engine Features:**
+
+**1. Protocol Loading & Validation:**
+- Loads experiment steps and actions from database
+- Validates step sequences and action parameters
+- Supports conditional step execution based on variables
+- Action timeout handling and required/optional distinction
+
+**2. Action Execution Dispatch:**
+- **Wizard Actions**: `wizard_say`, `wizard_gesture`, `wizard_show_object`
+- **Observation Actions**: `observe_behavior` with wizard completion tracking
+- **Control Actions**: `wait` with configurable duration
+- **Robot Actions**: Plugin-based dispatch (e.g., `turtlebot3.move`, `pepper.speak`)
+- Simulated robot actions with success/failure rates for testing
+
+**3. Real-time State Management:**
+- Trial execution context with variables and current step tracking
+- Step progression with automatic advancement after completion
+- Action completion validation before step advancement
+- Comprehensive event logging to `trial_events` table
+
+**4. Error Handling & Recovery:**
+- Action execution failure handling with optional/required distinction
+- Trial abort capabilities with reason logging
+- Step failure recovery and manual wizard override
+- Execution engine cleanup on trial completion/abort
+
+#### **🔧 Integration Points:**
+
+**Experiment Designer Connection:**

+- Executes visual protocol designs in real-time trials
+- Supports all core block types (events, wizard, control, observe)
+- Parameter validation and execution context binding
+
+**Robot Plugin System:**
+- Action execution through existing plugin architecture
+- Robot status monitoring via `RobotStatus` component
+- Plugin-based action dispatch with timeout and retry logic
