+# Interactive Dashboard - Living Documentation
+
+**Last Updated**: 2025-11-27
+**Status**: Initial Implementation Complete
+**Version**: 0.1.0
+
+## Overview
+
+This document tracks the design decisions, architecture, usage patterns, and evolution of the Interactive Multi-Page Dashboard for the Court Scheduling System.
+
+## Purpose and Goals
+
+The dashboard provides three key functionalities:
+1. **EDA Analysis** - Visualize and explore court case data patterns
+2. **Ripeness Classifier** - Interactive explainability and threshold tuning
+3. **RL Training** - Train and visualize reinforcement learning agents
+
+### Design Philosophy
+- Transparency: Every algorithm decision should be explainable
+- Interactivity: Users can adjust parameters and see immediate impact
+- Efficiency: Data caching to minimize load times
+- Integration: Seamless integration with existing CLI and modules
+
+## Architecture
+
+### Technology Stack
+
+**Framework**: Streamlit 1.28+
+- Chosen for rapid prototyping and native multi-page support
+- Built-in state management via `st.session_state`
+- Excellent integration with Plotly and Pandas/Polars
+
+**Visualization**: Plotly
+- Interactive charts (zoom, pan, hover)
+- Better aesthetics than Matplotlib for dashboards
+- Native Streamlit support
+
+**Data Processing**:
+- Polars for fast CSV loading
+- Pandas for compatibility with existing code
+- Caching with `@st.cache_data` decorator
+
+### Directory Structure
+
+```
+scheduler/
+  dashboard/
+    __init__.py           # Package initialization
+    app.py                # Main entry point (home page)
+    utils/
+      __init__.py
+      data_loader.py      # Cached data loading functions
+    pages/
+      1_EDA_Analysis.py           # EDA visualizations
+      2_Ripeness_Classifier.py    # Ripeness explainability
+      3_RL_Training.py            # RL training interface
+```
+
+### Module Reuse Strategy
+
+The dashboard reuses existing components without duplication:
+- `scheduler.data.param_loader.ParameterLoader` - Load EDA-derived parameters
+- `scheduler.data.case_generator.CaseGenerator` - Load generated cases
+- `scheduler.core.ripeness.RipenessClassifier` - Classification logic
+- `scheduler.core.case.Case` - Case data structure
+- `rl.training.train_agent()` - RL training (future integration)
+
+## Page Implementations
+
+### Page 1: EDA Analysis
+
+**Features**:
+- Key metrics dashboard (total cases, adjournment rates, stages)
+- Interactive filters (case type, stage)
+- Multiple visualizations:
+  - Case distribution by type (bar chart + pie chart)
+  - Stage analysis (bar chart + pie chart)
+  - Adjournment patterns (bar charts by type and stage)
+  - Adjournment probability heatmap (stage × case type)
+- Raw data viewer with download capability
+
+**Data Sources**:
+- `Data/processed/cleaned_cases.csv` - Cleaned case data from EDA pipeline
+- `configs/parameters/` - Pre-computed parameters from ParameterLoader
+
+**Design Decisions**:
+- Use tabs instead of separate sections for better organization
+- Show top 10/15 items in charts to avoid clutter
+- Provide download button for filtered data
+- Cache data with 1-hour TTL to balance freshness and performance
+
+### Page 2: Ripeness Classifier
+
+**Features**:
+- **Tab 1: Configuration**
+  - Display current thresholds
+  - Stage-specific rules table
+  - Decision tree logic explanation
+- **Tab 2: Interactive Testing**
+  - Synthetic case creation
+  - Real-time classification with explanations
+  - Feature importance visualization
+  - Criteria pass/fail breakdown
+- **Tab 3: Batch Classification**
+  - Load generated test cases
+  - Classify all with current thresholds
+  - Show distribution (RIPE/UNRIPE/UNKNOWN)
+
+**State Management**:
+- Thresholds stored in `st.session_state`
+- Sidebar sliders for real-time adjustment
+- Reset button to restore defaults
+- Session-based (not persisted to disk)
+
+**Explainability Approach**:
+- Clear criteria breakdown (service hearings, case age, stage days, keywords)
+- Visual indicators (✓/✗) for pass/fail
+- Feature importance bar chart
+- Before/after comparison capability
+
+**Design Decisions**:
+- Simplified classification logic for demo (uses basic criteria)
+- Future: Integrate actual RipenessClassifier.classify_case()
+- Stage-specific rules hardcoded for now (future: load from config)
+- Color coding: green (RIPE), orange (UNKNOWN), red (UNRIPE)
+
+### Page 3: RL Training
+
+**Features**:
+- **Tab 1: Train Agent**
+  - Configuration form (episodes, learning rate, epsilon, etc.)
+  - Training progress visualization (demo mode)
+  - Multiple live charts (disposal rate, rewards, states, epsilon decay)
+  - Command generation for CLI training
+- **Tab 2: Training History**
+  - Load and display previous training runs
+  - Plot historical performance
+- **Tab 3: Model Comparison**
+  - Load saved models from models/ directory
+  - Compare Q-table sizes and hyperparameters
+  - Visualization of model differences
+
+**Demo Mode**:
+- Current implementation simulates training results
+- Generates synthetic stats for visualization
+- Shows CLI command for actual training
+- Future: Integrate real-time training with rl.training.train_agent()
+
+**Design Decisions**:
+- Demo mode chosen for initial release (no blocking UI during training)
+- Future: Add async training with progress updates
+- Hyperparameter guide in expander for educational value
+- Model persistence via pickle (existing pattern)
+
+## CLI Integration
+
+### Command
+```bash
+uv run court-scheduler dashboard [--port PORT] [--host HOST]
+```
+
+**Default**: `http://localhost:8501`
+
+**Implementation**:
+- Added to `cli/main.py` as `@app.command()`
+- Uses subprocess to launch Streamlit
+- Validates dashboard app.py exists before launching
+- Handles KeyboardInterrupt gracefully
+
+**Usage Example**:
+```bash
+# Launch on default port
+uv run court-scheduler dashboard
+
+# Custom port
+uv run court-scheduler dashboard --port 8080
+
+# Bind to all interfaces
+uv run court-scheduler dashboard --host 0.0.0.0 --port 8080
+```
+
+## Data Flow
+
+### Loading Sequence
+1. User launches dashboard via CLI
+2. `app.py` loads, displays home page and system status
+3. User navigates to a page (e.g., EDA Analysis)
+4. Page imports data_loader utilities
+5. `@st.cache_data` checks cache for data
+6. If not cached, load from disk and cache
+7. Data processed and visualized
+8. User interactions trigger re-renders (cached data reused)
+
+### Caching Strategy
+- **TTL**: 3600 seconds (1 hour) for data files
+- **No TTL**: For computed statistics (invalidates on data change)
+- **Session State**: For UI state (thresholds, training configs)
+
+### Performance Considerations
+- Polars for fast CSV loading
+- Limit DataFrame display to first 100 rows
+- Top N filtering for visualizations (top 10/15)
+- Lazy loading (pages only load data when accessed)
+
+## Usage Patterns
+
+### Typical Workflow 1: EDA Exploration
+1. Run EDA pipeline: `uv run court-scheduler eda`
+2. Launch dashboard: `uv run court-scheduler dashboard`
+3. Navigate to EDA Analysis page
+4. Apply filters (case type, stage)
+5. Explore visualizations
+6. Download filtered data if needed
+
+### Typical Workflow 2: Threshold Tuning
+1. Generate test cases: `uv run court-scheduler generate`
+2. Launch dashboard: `uv run court-scheduler dashboard`
+3. Navigate to Ripeness Classifier page
+4. Adjust thresholds in sidebar
+5. Test with synthetic case (Tab 2)
+6. Run batch classification (Tab 3)
+7. Analyze impact on RIPE/UNRIPE distribution
+
+### Typical Workflow 3: RL Training
+1. Launch dashboard: `uv run court-scheduler dashboard`
+2. Navigate to RL Training page
+3. Configure hyperparameters (Tab 1)
+4. Copy CLI command and run separately (or use demo)
+5. Return to dashboard, view history (Tab 2)
+6. Compare models (Tab 3)
+

+
+## Troubleshooting
+
+### Common Issues
+
+**Issue**: Dashboard won't launch
+- **Check**: Is Streamlit installed? `pip list | grep streamlit`
+- **Solution**: Ensure venv is activated, run `uv sync`
+
+**Issue**: "Data file not found" warnings
+- **Check**: Has EDA pipeline been run?
+- **Solution**: Run `uv run court-scheduler eda`
+
+**Issue**: Empty visualizations
+- **Check**: Is `Data/processed/cleaned_cases.csv` empty?
+- **Solution**: Verify EDA pipeline completed successfully
+
+**Issue**: Ripeness batch classification fails
+- **Check**: Are test cases generated?
+- **Solution**: Run `uv run court-scheduler generate`
+
+**Issue**: Slow page loads
+- **Check**: Is data being cached?
+- **Solution**: Check Streamlit cache, reduce data size
+
+## Design Decisions Log
+
+### Decision 1: Streamlit over Dash/Gradio
+**Date**: 2025-11-27
+**Rationale**: 
+- Already in dependencies (no new install)
+- Simpler multi-page support
+- Better for data science workflows
+- Faster development time
+
+**Alternatives Considered**:
+- Dash: More customizable but more boilerplate
+- Gradio: Better for ML demos, less flexible
+
+### Decision 2: Plotly over Matplotlib
+**Date**: 2025-11-27
+**Rationale**:
+- Interactive by default (zoom, pan, hover)
+- Better aesthetics for dashboards
+- Native Streamlit integration
+- Users expect interactivity in modern dashboards
+
+**Note**: Matplotlib still used for static EDA plots already generated
+
+### Decision 3: Session State for Thresholds
+**Date**: 2025-11-27
+**Rationale**:
+- Ephemeral experimentation (users can reset easily)
+- No need to persist to disk
+- Simpler implementation
+- Users can export configs separately if needed
+
+**Future**: May add "save configuration" feature
+
+### Decision 4: Demo Mode for RL Training
+**Date**: 2025-11-27
+**Rationale**:
+- Avoid blocking UI during long training runs
+- Show visualization capabilities
+- Guide users to use CLI for actual training
+- Simpler initial implementation
+
+**Future**: Add async training with WebSocket updates
+
+### Decision 5: Simplified Ripeness Logic
+**Date**: 2025-11-27
+**Rationale**:
+- Demonstrate explainability concept
+- Avoid tight coupling with RipenessClassifier implementation
+- Easier to understand for users
+- Placeholder for full integration
+
+**Future**: Integrate actual RipenessClassifier.classify_case()
+
+## Maintenance Notes
+
+### Dependencies
+- Streamlit: Keep updated for security fixes
+- Plotly: Monitor for breaking changes
+- Polars: Ensure compatibility with Pandas conversion
+
+### Code Quality
+- Follow project ruff/black style
+- Add docstrings to new functions
+- Keep pages under 350 lines if possible
+- Extract reusable components to utils/
+
+### Performance Monitoring
+- Monitor cache hit rates
+- Track page load times
+- Watch for memory leaks with large datasets
+
+## Educational Value
+
+The dashboard serves an educational purpose:
+- **Transparency**: Shows how algorithms work (ripeness classifier)
+- **Interactivity**: Lets users experiment (threshold tuning)
+- **Visualization**: Makes complex data accessible (EDA plots)
+- **Learning**: Explains RL concepts (hyperparameter guide)
+
+This aligns with the "explainability" goal of the Code4Change project.
+
+## Conclusion
+
+The dashboard successfully provides:
+1. Comprehensive EDA visualization
+2. Full ripeness classifier explainability
+3. RL training interface (demo mode)
+4. CLI integration
+5. Cached data loading
+6. Interactive threshold tuning
+
+Next steps focus on integrating real RL training and enhancing the ripeness classifier with actual implementation.

+        - Each stage has minimum days requirement
+        - If `days_in_stage < stage_requirement` → **UNRIPE**
+        
+        **4. Keyword Analysis**
+        - Certain keywords indicate ripeness (e.g., "reply filed", "arguments complete")
+        - If keywords found → **RIPE**
+

+            
+            Reinforcement Learning trains an agent to make optimal scheduling decisions
+            by learning from simulated court scheduling scenarios.
+            
+            The agent learns to:
+            - Prioritize cases effectively
+            - Balance workload across courtrooms
+            - Maximize disposal rates
+            - Minimize adjournments
+            
+            **Key Hyperparameters:**
+            - **Episodes**: Number of complete training runs
+            - **Learning Rate**: How fast the agent updates its knowledge
+            - **Epsilon**: Balance between exploration (try new actions) and exploitation (use known good actions)
+            - **Discount Factor**: How much to value future rewards vs immediate rewards
