games/<game>/
  ├── run_config.toml  # ⭐ NEW: Runtime settings (threads, compression, pipeline)
  ├── run.py           # Pure execution script (reads from TOML)
  └── game_state.py     # All game logic in one file (~100-400 lines)

• Easier to understand - all game logic in one place
• Easier to debug - no jumping between 4+ files
• Easier to maintain - changes don't require coordinating across layers
• Easier to create new games - clear, self-contained template
• NEW: TypeScript-like TOML config - familiar pattern for web developers

TOML-Based Configuration (NEW!)

[execution]
num_threads = 10        # Python simulation threads
compression = false     # Enable zstd compression
profiling = false       # Enable performance profiling

[simulation]
base = 10000           # Base game simulations
bonus = 10000          # Bonus game simulations

[pipeline]
run_sims = true            # Generate simulation books
run_optimization = true    # Run Rust optimization
run_analysis = true        # Generate PAR sheets

target_modes = ["base", "bonus"]

make run GAME=tower_treasures                    # Uses default run_config.toml
make run GAME=tower_treasures CONFIG=dev.toml    # Development: fast iteration, small samples
make run GAME=tower_treasures CONFIG=prod.toml   # Production: 1M simulations, full optimization
make run GAME=tower_treasures CONFIG=test.toml   # Testing: minimal config for CI/CD

• dev.toml - Development: Small simulations (1K), no optimization, fast feedback (~10 seconds)
• prod.toml - Production: Large simulations (1M), full optimization, accurate stats (~2 hours)
• test.toml - Testing: Minimal simulations (100), for automated tests/CI
• run_config.toml - Default: Can be symlinked to dev.toml or prod.toml

• Familiar pattern for TypeScript/JavaScript developers
• Switch between configs without editing code
• Version control friendly (track config changes separately)
• No need to modify Python code to change settings

Using Output Optimization (Phase 3)

from src.output.output_formatter import OutputMode

config = GameConfig()

# Enable output compression (Phase 3.1)
config.output_mode = OutputMode.COMPACT  # 27.9% reduction
config.compress_symbols = True
config.compress_positions = True

# Enable event filtering (Phase 3.2) - additional 10-15% reduction
config.skip_derived_wins = True  # Skip SET_WIN, SET_TOTAL_WIN
config.skip_progress_updates = True  # Skip UPDATE_* events
config.verbose_event_level = "standard"  # "minimal", "standard", or "full"

• Compact mode alone: 27.9% smaller files, 13% faster generation
• With filtering: 35-40% total reduction from baseline
• Example: 10K simulations reduced from 18.89 MB to 11-12 MB

• docs/ - User guides and tutorials 
  • Running Games - How to run simulations and build books
  • Game Structure - Architecture and file organization
  • Optimization - Using the optimization algorithm
  • Events - Event system guide
  • Testing - Writing and running tests
• CLAUDE.md - Comprehensive technical reference

🗜️ Output Optimization (Phase 3 - NEW!)

• Intelligent compression - 27.9% file size reduction through OutputFormatter with COMPACT mode
• Event filtering - Additional 10-15% reduction via selective event emission with EventFilter
• Performance boost - 13% faster generation with compact mode
• Smart formatting - Symbol compression ("L5" vs {"name": "L5"}), position arrays ([0,2] vs {"reel": 0, "row": 2})
• Configurable verbosity - Three event levels (minimal/standard/full) for different use cases
• Format versioning - Built-in version tracking for forward compatibility
• Production tested - 54 comprehensive tests, RGS verified, fully backward compatible

📝 JSON Output Formatting

• Automatic JSON formatting when compression is disabled - books files are automatically formatted with proper indentation for better readability
• Smart formatting logic that keeps simple name objects (like {"name": "L1"}) compact while pretty-printing complex structures
• Integrated formatting pipeline - formatting runs automatically after simulation via the Makefile
• Advanced error handling with JSONL reconstruction capabilities for corrupted files

🏷️ Standardized Event Names

• Event constants system - All event types are now defined in EventConstants enum for consistency
• Centralized event management - No more hardcoded event strings scattered throughout the codebase
• Type safety - Using constants prevents typos and ensures consistent event naming across the SDK
• Comprehensive event coverage - Standardized events for wins, free spins, tumbles, reveals, and special symbols

🧪 Unit Testing Framework

• Game-specific unit tests - Each game can have its own dedicated test suite
• Isolated testing - Test individual components without requiring full game simulation
• Fast execution - Quick feedback during development with focused test cases
• Test automation - Integrated with Makefile for easy test running (make unittest GAME=<game_name>)
• Example implementations - Tower defense game includes comprehensive sticky symbols tests

🔧 Enhanced Development Workflow

• Improved Makefile - Added commands for unit testing and automated formatting
• Better error reporting - More detailed error messages and debugging information
• Documentation enhancements - Comprehensive docs for events, testing, and formatting systems
• Development tools - Scripts for JSON formatting and game analytics

📊 Advanced Analytics & Debugging

• Enhanced game analytics - Better tools for analyzing simulation results and win distributions
• Force record improvements - More detailed tracking of custom-defined events and search keys
• Simulation validation - Better verification tools for ensuring data integrity
• Statistics export - Improved JSON and Excel export capabilities for PAR sheets

🎮 Game Development Features

• Sticky symbols support - Built-in framework for implementing sticky symbol mechanics
• Event-driven architecture - Enhanced event system for better game state management
• Flexible configuration - More options for customizing game behavior and output formats
• Template improvements - Better game templates and examples for faster development
