+# Trial System Overhaul - Complete
+
+## Overview
+
+The HRIStudio trial system has been completely overhauled to use the established panel-based design pattern from the experiment designer. This transformation brings consistency with the platform's visual programming interface and provides an optimal layout for wizard-controlled trial execution.
+
+## Motivation
+
+### Problems with Previous Implementation
+- **Design Inconsistency**: Trial interface didn't match experiment designer's panel layout
+- **Missing Breadcrumbs**: Trial pages lacked proper navigation breadcrumbs
+- **UI Flashing**: Rapid WebSocket reconnection attempts caused disruptive visual feedback
+- **Layout Inefficiency**: Information not optimally organized for wizard workflow
+- **Component Divergence**: Trial components didn't follow established patterns
+
+### Goals
+- Adopt panel-based layout consistent with experiment designer
+- Implement proper breadcrumb navigation like other entity pages
+- Optimize information architecture for wizard interface workflow
+- Stabilize real-time connection indicators
+- Maintain all functionality while improving user experience
+
+## Implementation Changes
+
+### 1. Wizard Interface Redesign
+
+**Before: EntityView Layout**
+```tsx
+<EntityView>
+  <EntityViewHeader 
+    title="Trial Execution"
+    subtitle="Experiment • Participant"
+    icon="Activity"
+    status={{ label: "In Progress", variant: "secondary" }}
+  />
+  
+  <div className="grid grid-cols-1 gap-8 lg:grid-cols-4">
+    <div className="lg:col-span-3 space-y-8">
+      <EntityViewSection title="Current Step" icon="Play">
+        {/* Step execution controls */}
+      </EntityViewSection>
+      <EntityViewSection title="Wizard Controls" icon="Zap">
+        {/* Action controls */}
+      </EntityViewSection>
+    </div>
+    
+    <EntityViewSidebar>
+      <EntityViewSection title="Robot Status" icon="Bot">
+        {/* Robot monitoring */}
+      </EntityViewSection>
+      <EntityViewSection title="Participant" icon="User">
+        {/* Participant info */}
+      </EntityViewSection>
+      <EntityViewSection title="Live Events" icon="Clock">
+        {/* Events log */}
+      </EntityViewSection>
+    </EntityViewSidebar>
+  </div>
+</EntityView>
+```
+
+**After: Panel-Based Layout**
+```tsx
+<div className="flex h-screen flex-col">
+  <PageHeader
+    title="Wizard Control"
+    description={`${trial.experiment.name} • ${trial.participant.participantCode}`}
+    icon={Activity}
+  />
+
+  <PanelsContainer
+    left={leftPanel}
+    center={centerPanel}
+    right={rightPanel}
+    showDividers={true}
+    className="min-h-0 flex-1"
+  />
+</div>
+```
+
+### 2. Panel-Based Architecture
+
+**Left Panel - Trial Controls & Navigation**
+- **Trial Status**: Visual status indicator with elapsed time and progress
+- **Trial Controls**: Start/Next Step/Complete/Abort buttons
+- **Step List**: Visual step progression with current position highlighted
+- **Compact Design**: Optimized for quick access to essential controls
+
+**Center Panel - Main Execution Area** 
+- **Current Step Display**: Prominent step name, description, and navigation
+- **Wizard Actions**: Full-width action controls interface
+- **Connection Alerts**: Stable WebSocket status indicators
+- **Trial State Management**: Scheduled/In Progress/Completed views
+
+**Right Panel - Monitoring & Context**
+- **Robot Status**: Real-time robot monitoring with mock integration
+- **Participant Info**: Essential participant context
+- **Live Events**: Scrollable event log with timestamps
+- **Connection Details**: Technical information and trial metadata
+
+### 3. Breadcrumb Navigation
+```typescript
+useBreadcrumbsEffect([
+  { label: "Dashboard", href: "/dashboard" },
+  { label: "Studies", href: "/studies" },
+  { label: studyData.name, href: `/studies/${studyData.id}` },
+  { label: "Trials", href: `/studies/${studyData.id}/trials` },
+  { label: `Trial ${trial.participant.participantCode}`, href: `/trials/${trial.id}` },
+  { label: "Wizard Control" },
+]);
+```
+
+### 4. Component Integration
+
+**PanelsContainer Integration**
+- Reused proven layout system from experiment designer
+- Drag-resizable panels with overflow containment
+- Consistent spacing and visual hierarchy
+- Full-height layout optimization
+
+**PageHeader Standardization**
+- Matches pattern used across all entity pages
+- Proper icon and description placement
+- Consistent typography and spacing
+
+**WebSocket Stability Improvements**
+```typescript
+// Stable connection status in right panel
+<Badge variant={wsConnected ? "default" : "secondary"}>
+  {wsConnected ? "Connected" : "Polling"}
+</Badge>
+```
+
+**Development Mode Optimization**
+- Disabled aggressive reconnection attempts in development
+- Stable "Polling Mode" indicator instead of flashing states
+- Clear messaging about development limitations
+
+## Technical Benefits
