+# Pokemon Table Implementation
+
+This document describes the high-performance Pokemon data table implementation for the Pokemon Battle Simulator.
+
+## Overview
+
+The Pokemon Table is a high-performance data structure that provides O(1) lookup access to all Pokemon species data. It loads Pokemon data from JSON files and stores them in memory for fast runtime access.
+
+## Features
+
+- **O(1) ID-based lookup**: Access any Pokemon by its ID in constant time
+- **O(1) Name-based lookup**: Access any Pokemon by its name using a hash map
+- **Automatic data loading**: Loads all Pokemon data from JSON files at startup
+- **Memory efficient**: Uses contiguous memory storage for optimal cache performance
+- **Type safety**: Strongly typed with comprehensive error handling
+- **Validation**: Built-in data validation to ensure integrity
+
+## Architecture
+
+### Core Classes
+
+#### `PokemonTable`
+The main class that manages the Pokemon data table.
+
+**Key Methods:**
+- `loadFromDataDirectory()`: Loads Pokemon data from the standard data directory
+- `loadFromFiles()`: Loads Pokemon data from specific JSON files
+- `getPokemon(uint16_t id)`: O(1) lookup by Pokemon ID
+- `getPokemonByName(std::string_view name)`: O(1) lookup by Pokemon name
+- `hasPokemon(uint16_t id)`: Check if a Pokemon ID exists
+- `size()`: Get the total number of loaded Pokemon
+- `validate()`: Validate the integrity of loaded data
+
+#### `PokemonSpecies`
+Struct containing all the data for a single Pokemon species.
+
+**Fields:**
+- `id`: Pokemon ID (1-based)
+- `name`: Pokemon name
+- `base_stats`: Base stats (HP, Attack, Defense, SpAttack, SpDefense, Speed)
+- `types`: Primary and secondary types
+
+### Global Access
+
+The implementation provides a global Pokemon table instance for convenient access:
+
+```cpp
+#include "core/pokemon_table.h"
+
+// Initialize the global table (call once at startup)
+bool success = PokEng::initializePokemonTable();
+
+// Use the global table
+const auto* bulbasaur = PokEng::g_pokemonTable->getPokemon(1);
+const auto* charizard = PokEng::g_pokemonTable->getPokemonByName("charizard");
+
+// Clean up (call at shutdown)
+PokEng::shutdownPokemonTable();
+```
+
+## Performance
+
+### Benchmarks
+
+Based on the example program, the Pokemon table demonstrates excellent performance:
+
+- **Initialization**: ~89ms to load 1025 Pokemon species
+- **ID Lookups**: ~33,333 lookups per millisecond (100,000 lookups in 3ms)
+- **Memory Usage**: Minimal memory footprint with contiguous storage
+
+### Storage Strategy
+
+The table uses a hybrid storage approach for optimal performance:
+
+1. **Vector storage**: Pokemon species are stored in a `std::vector<PokemonSpecies>` indexed by ID
+2. **Hash map**: Name-to-ID mapping using `std::unordered_map` for fast name lookups
+3. **Index 0 unused**: Vector index 0 is unused, so Pokemon with ID 1 is at index 1
+
+This approach provides:
+- O(1) ID lookups via direct vector indexing
+- O(1) average case name lookups via hash table
+- Excellent cache locality for ID-based access patterns
+
+## Usage Examples
+
+### Basic Usage
+
+```cpp
+#include "core/pokemon_table.h"
+
+int main() {
+    // Initialize the Pokemon table
+    if (!PokEng::initializePokemonTable()) {
+        std::cerr << "Failed to load Pokemon data!" << std::endl;
+        return 1;
+    }
+
+    // Look up Pokemon by ID
+    const auto* pikachu = PokEng::g_pokemonTable->getPokemon(25);
+    if (pikachu) {
+        std::cout << "Pikachu's speed: " << pikachu->base_stats.speed << std::endl;
+        std::cout << "Pikachu's type: " << PokEng::TypeUtils::typeToString(pikachu->types.getPrimary()) << std::endl;
+    }
+
+    // Look up Pokemon by name
+    const auto* charizard = PokEng::g_pokemonTable->getPokemonByName("charizard");
+    if (charizard) {
+        std::cout << "Charizard ID: " << charizard->id << std::endl;
+    }
+
+    // Clean up
+    PokEng::shutdownPokemonTable();
+    return 0;
+}
+```
+
+### Advanced Usage
+
+```cpp
+// Check if Pokemon exists
+if (PokEng::g_pokemonTable->hasPokemon(150)) {
+    const auto* mewtwo = PokEng::g_pokemonTable->getPokemon(150);
+    // Use mewtwo data...
+}
+
+// Iterate through all Pokemon
+for (uint16_t id = 1; id <= PokEng::g_pokemonTable->getMaxId(); ++id) {
+    const auto* pokemon = PokEng::g_pokemonTable->getPokemon(id);
+    if (pokemon) {
+        // Process pokemon...
+    }
+}
+
+// Get all Pokemon at once (for bulk operations)
+const auto& allPokemon = PokEng::g_pokemonTable->getAllPokemon();
+for (const auto& pokemon : allPokemon) {
+    if (pokemon.id != 0) { // Skip empty entries
+        // Process pokemon...
+    }
+}
+```
+
+## Data Loading
+
+The Pokemon table automatically loads data from JSON files in the `data/pokemon/` directory:
+
+- `generation-i.json` through `generation-ix.json`
+- Each file contains Pokemon from a specific generation
+- Data is validated during loading
+
+### JSON Format
+
+Each Pokemon entry in the JSON files has the following structure:
+
+```json
+{
+  "id": 1,
+  "name": "bulbasaur",
+  "height": 7,
+  "weight": 69,
+  "base_experience": 64,
+  "types": ["grass", "poison"],
+  "stats": {
+    "hp": 45,
+    "attack": 49,
+    "defense": 49,
+    "special-attack": 65,
+    "special-defense": 65,
+    "speed": 45
+  },
+  "abilities": [...],
+  "species": {...}
+}
+```
+
+## Error Handling
+
+The implementation includes comprehensive error handling:
+
+- **File loading errors**: Graceful handling of missing or corrupted JSON files
+- **JSON parsing errors**: Detailed error messages for malformed JSON
+- **Data validation**: Built-in validation to ensure data integrity
+- **Memory safety**: Proper resource management with RAII
+
+## Testing
+
+The implementation includes comprehensive unit tests covering:
+
+- Data loading and initialization
+- ID-based and name-based lookups
+- Error handling for invalid inputs
+- Performance validation
+- Data integrity validation
+
+Run tests with:
+```bash
+cd build
+make test
+```
+
+## Integration
+
+The Pokemon table is designed to integrate seamlessly with other components:
+
+- **Pokemon creation**: Use table data to create Pokemon instances
+- **Battle calculations**: Fast access to base stats and types
+- **Type effectiveness**: Integration with type system for damage calculations
+- **Stat calculations**: Base stats for battle stat computations
+
+## Future Enhancements
+
+Potential improvements for the Pokemon table:
+
+1. **Lazy loading**: Load Pokemon data on-demand to reduce startup time
+2. **Compressed storage**: Use compression to reduce memory footprint
+3. **Multi-threading**: Parallel loading of Pokemon data
+4. **Caching**: Implement LRU cache for frequently accessed Pokemon
+5. **Serialization**: Save/load compiled Pokemon data for faster startup

-# Pokemon Type System Implementation
-
-This document describes the high-performance Pokemon type system implementation for the Pokemon Battle Simulator.
-
-## Overview
-
-The type system provides:
-- **High-performance type effectiveness calculations** using integer arithmetic only
-- **Multi-generation support** without runtime generation checks
-- **Dual-type Pokemon support** with proper damage multiplier calculations
-- **JSON-based type chart loading** from the provided data files
-- **Comprehensive testing and benchmarking** for performance validation
-
-## Key Features
-
-### 1. Performance Optimizations
-
-- **Integer-only arithmetic**: Uses integer multipliers (0, 1, 2, 4, 8, 16) representing (0x, 0.25x, 0.5x, 1x, 2x, 4x) damage
-- **Compile-time generation selection**: Template-based generation support eliminates runtime checks
-- **Cache-friendly type chart storage**: 2D array layout optimized for CPU cache performance
-- **Minimal memory allocations**: Static storage for type charts loaded at startup
-
-### 2. Type System Architecture
-
-#### Core Components
-
-- **`Type` enum**: All 19 Pokemon types (Generation 1-9)
-- **`TypeMultiplier` enum**: Integer damage multipliers
-- **`Generation` enum**: Pokemon game generations
-- **`PokemonTypes` class**: Represents single/dual-type Pokemon
-- **`TypeUtils` class**: Core type system functionality
-- **`TypeChartTraits` template**: Generation-specific type chart access
-
-#### Type Multipliers
-
-```cpp
-enum class TypeMultiplier : uint8_t {
-    ZERO = 0,      // 0x damage (immune)
-    QUARTER = 1,   // 0.25x damage
-    HALF = 2,      // 0.5x damage
-    NEUTRAL = 4,   // 1x damage (neutral)
-    DOUBLE = 8,    // 2x damage
-    QUADRUPLE = 16 // 4x damage
-};
-```
-
-### 3. Usage Examples
-
-#### Basic Type Effectiveness
-
-```cpp
-using namespace PokEng;
-
-// Calculate damage with type effectiveness
-uint32_t damage = calculateTypeDamage<Generation::I>(
-    100,                    // Base damage
-    Type::WATER,           // Attack type
-    Type::FIRE             // Defender type
-);
-// Result: 200 (Water is super effective against Fire)
-```
-
-#### Dual-Type Pokemon
-
-```cpp
-// Electric attack on Water/Flying Pokemon
-uint32_t damage = calculateTypeDamage<Generation::I>(
-    100,                    // Base damage
-    Type::ELECTRIC,        // Attack type
-    Type::WATER,           // Primary defender type
-    Type::FLYING           // Secondary defender type
-);
-// Result: 400 (Electric is super effective against both types)
-```
-
-#### Pokemon with Types
-
-```cpp
-// Create Pokemon with types
-Pokemon charizard("Charizard", 150, Type::FIRE, Type::FLYING);
-Pokemon blastoise("Blastoise", 150, Type::WATER);
-
-// Calculate damage using Pokemon methods
-uint32_t damage = charizard.calculateDamageTaken<Generation::I>(
-    100,           // Base damage
-    Type::WATER    // Attack type
-);
-// Result: 200 (Water is super effective against Fire)
-```
-
-### 4. Generation Support
-
-The system supports all Pokemon generations through compile-time templates:
-
-```cpp
-// Generation 1 type effectiveness
-auto gen1Damage = calculateTypeDamage<Generation::I>(100, Type::FIRE, Type::WATER);
-
-// Generation 8 type effectiveness
-auto gen8Damage = calculateTypeDamage<Generation::VIII>(100, Type::FIRE, Type::WATER);
-```
-
-Each generation has its own type chart loaded from the corresponding JSON file.
-
-### 5. Type Chart Loading
-
-Type charts are loaded from JSON files at program startup:
-
-- `data/type_effectiveness_generation-i.json` → Generation 1
-- `data/type_effectiveness_generation-ii.json` → Generation 2
-- ... and so on through Generation 9
-
-The loading process:
-1. Parses JSON using RapidJSON
-2. Converts float multipliers to integer TypeMultiplier values
-3. Stores in optimized 2D array format
-4. Provides O(1) lookup performance
-
-## Performance Characteristics
-
-### Benchmarks
-
-The implementation includes comprehensive benchmarks:
-
-```bash
-# Run type system benchmarks
-./build/benchmarks/benchmarks
-
-# Run specific benchmark
-./build/benchmarks/benchmarks --benchmark_filter=TypeSystemBenchmark
-```
-
-Key benchmark results (example):
-- **Type effectiveness lookup**: ~1-2 nanoseconds
-- **Damage multiplier calculation**: ~2-3 nanoseconds
-- **Full damage calculation**: ~3-5 nanoseconds
-- **Batch processing**: Sub-microsecond for realistic scenarios
-
-### Memory Layout
-
-- Type charts: ~3KB per generation (19x19 types)
-- Total memory: ~27KB for all 9 generations
-- Cache-friendly access pattern: Row-major order for optimal CPU cache usage
-
-## Testing
-
-### Unit Tests
-
-Comprehensive unit test coverage:
-
-```bash
-# Run type system tests
-./build/tests/unit/core/test_types
-
-# Run all tests
-./build/tests/test_all.sh
-```
-
-Test categories:
-- **Type string conversion**: Valid/invalid conversions
-- **Type effectiveness**: Known type matchups
-- **Damage calculations**: Single/dual-type scenarios
-- **Edge cases**: Immunity, invalid inputs
-- **Generation differences**: Cross-generation behavior
-- **Performance**: Speed validation
-
-### Example Output
-
-```cpp
-// Test: Water attack on Fire type
-uint32_t damage = calculateTypeDamage<Generation::I>(100, Type::WATER, Type::FIRE);
-ASSERT_EQ(damage, 200);  // Water is super effective (2x) against Fire
-
-// Test: Dual-type Electric attack on Water/Flying
-uint32_t dualDamage = calculateTypeDamage<Generation::I>(100, Type::ELECTRIC, Type::WATER, Type::FLYING);
-ASSERT_EQ(dualDamage, 400);  // Electric is super effective (2x) against both types = 4x total
-```
-

-
-## Building and Running
-
-### Dependencies
-
-- C++17 compatible compiler
-- RapidJSON (header-only, included in `thirdParty/rapidjson`)
-- CMake 3.15+
-- Google Test (for unit tests)
-- Google Benchmark (for performance tests)
-
-### Build Commands
-
-```bash
-# Configure
-cmake -B build -S . -DCMAKE_BUILD_TYPE=Release
-
-# Build
-cmake --build build --config Release
-
-# Run tests
-cd build && ctest --output-on-failure
-
-# Run benchmarks
-./benchmarks/benchmarks
-
-# Run example
-./examples/type_system_example
-```
-
-### Integration
-
-To use the type system in your code:
-
-```cpp
-#include "types.h"
-
-// Use the high-level API
-uint32_t damage = PokEng::calculateTypeDamage(
-    100, Type::FIRE, Type::GRASS
-);
-```
-
-## Design Decisions
-
-### Integer-Only Arithmetic
-
-- **Rationale**: Floating-point operations are slower and introduce precision issues
-- **Solution**: Use integer multipliers with division by 4 for final damage calculation
-- **Benefit**: 2-3x performance improvement over float-based calculations
-
-### Template-Based Generations
-
-- **Rationale**: Runtime generation checks would add overhead
-- **Solution**: Compile-time generation selection via templates
-- **Benefit**: Zero runtime overhead for generation selection
-
-### Static Type Charts
-
-- **Rationale**: Type effectiveness rarely changes during program execution
-- **Solution**: Load once at startup, store in static arrays
-- **Benefit**: Optimal cache performance for repeated lookups
-
-## Future Enhancements
-
-Potential improvements:
-1. **SIMD optimizations** for batch damage calculations
-2. **Memory-mapped file loading** for reduced startup time
-3. **Type combination caching** for frequently used type pairs
-4. **Custom type chart support** for ROM hacks/modifications
-5. **Advanced effectiveness rules** (e.g., Freeze Dry, Flying Press)
-
-## Contributing
-
-When extending the type system:
-1. Add new types to the `Type` enum
-2. Update string conversion mappings
-3. Add new JSON data files for type effectiveness
-4. Update template instantiations
-5. Add comprehensive unit tests
-6. Add performance benchmarks
-7. Update documentation

-## Examples
+#### Moves Data (`moves/generation-X.json`)
 
-### Basic Usage (Python API)
-
-```python
-from pathlib import Path
-from tools.data.pokemon_downloader import PokemonDownloader
-
-# Initialize downloader
-downloader = PokemonDownloader(
-    output_dir=Path("my_pokemon_data"),
-    validate_data=True
-)
-
-# Download first 10 Pokemon
-pokemon_data = downloader.download_pokemon_batch(1, 10)
-downloader.save_pokemon_data(pokemon_data, "starter_pokemon.json")
-
-# Download some moves
-move_ids = [1, 2, 3, 4, 5]  # Pound, Karate Chop, etc.
-moves_data = downloader.download_moves_batch(move_ids)
-downloader.save_moves_data(moves_data, "basic_moves.json")
-
-# Download type effectiveness
-effectiveness = downloader.download_type_effectiveness()
-downloader.save_type_effectiveness(effectiveness, "types.json")
+```json
+[
+  {
+    "id": 1,
+    "name": "pound",
+    "power": 40,
+    "pp": 35,
+    "accuracy": 100,
+    "type": "normal",
+    "damage_class": "physical",
+    "generation": "generation-i"
+  }
+]
 ```
 
-### Testing Small Segments
+### Dependencies
 
-```python
-# Test with just 3 Pokemon
-python tools/data/test_downloader.py
+The tool requires the following Python packages (available in `tools/requirements.txt`):
+
+- `requests` - HTTP requests to PokeAPI
+- `tqdm` - Progress bars
+- `argparse` - Command line argument parsing (built-in)
+
+### API Rate Limiting
+
+The tool includes:
+- Retry logic with exponential backoff
+- Respectful request timing
+- User-agent identification
+- Error handling for rate limits
+
+### New Features (Latest Update)
+
+**Efficient Moves Download:**
+- Downloads all moves once and saves to `data/all_moves.json`
+- Subsequent generations filter from this master file instead of re-downloading
+- Dramatically reduces API calls and download time
+
+**Smart Caching:**
+- Checks if data files already exist and contain expected amount of data
+- Skips re-downloading if files are present and valid
+- Supports partial downloads (e.g., if some Pokemon are missing, only downloads missing ones)
+
+**File Structure:**
+```
+data/
+├── all_moves.json          # Complete moves database (all generations)
+├── types/
+│   ├── generation-i.json   # Type effectiveness for each generation
+│   ├── generation-ii.json
+│   └── ...
+├── pokemon/
+│   ├── generation-i.json   # Pokemon data for each generation
+│   ├── generation-ii.json
+│   └── ...
+└── moves/
+    ├── generation-i.json   # Moves available in each generation
+    ├── generation-ii.json  # (filtered from all_moves.json)
+    └── ...
 ```
 
-### Custom Data Validation
+### Performance Improvements
 
-```python
-from tools.data.schemas import DataValidator
+- **Moves**: Downloads all 900+ moves once, then filters per generation
+- **Caching**: Checks file existence and validity before downloading
+- **Batch Processing**: Downloads complete datasets efficiently
+- **Resume Support**: Can continue interrupted downloads
 
-validator = DataValidator()
+### Usage Examples with Caching
 
-# Validate Pokemon data
-errors = validator.validate_pokemon_collection(pokemon_data)
-if errors:
-    print("Validation errors:", errors)
-```
-
-## Performance Considerations
-
-- **Rate Limiting**: The tool implements 100ms delays between API calls to be respectful
-- **Concurrent Workers**: Default of 5 workers balances speed with API courtesy
-- **Caching**: API responses are cached to avoid redundant requests
-- **Memory Usage**: Large datasets are processed in batches to manage memory
-
-## Recommended Usage Patterns
-
-### For Development/Testing
 ```bash
-# Start small - download just a few Pokemon
-python -m tools.data.pokemon_downloader download-pokemon --start 1 --end 3 --include-moves
+# First run - downloads all data
+python tools/data/pokemon_downloader.py --all-generations --all-data-types
 
-# Test specific Pokemon you're interested in
-python -m tools.data.pokemon_downloader download-pokemon --start 25 --end 25 --include-moves  # Pikachu
+# Subsequent runs - uses cached data (much faster!)
+python tools/data/pokemon_downloader.py --all-generations --all-data-types
+
+# Only downloads missing data
+python tools/data/pokemon_downloader.py --generations generation-v --data-types pokemon
 ```
 
-### For Production Data
-```bash
-# Download by generations or batches
-python -m tools.data.pokemon_downloader download-pokemon --start 1 --end 50 --include-moves
-python -m tools.data.pokemon_downloader download-pokemon --start 51 --end 100 --include-moves
-python -m tools.data.pokemon_downloader download-pokemon --start 101 --end 151 --include-moves
+### Notes
 
-# Always download type effectiveness data
-python -m tools.data.pokemon_downloader download-types
-```
-
-### For Complete Gen 1 Dataset
-```bash
-# One command for everything (will take several minutes)
-python -m tools.data.pokemon_downloader download-complete --start 1 --end 151
-```
-
-## Data Validation
-
-The tool includes comprehensive JSON schema validation:
-
-- **Pokemon Data**: Validates stats, types, abilities, and structure
-- **Move Data**: Validates power, accuracy, PP, and damage classes
-- **Type Effectiveness**: Validates damage multipliers and type names
-- **Generation 1 Focus**: Ensures only valid Gen 1 types and data
-
-Validation errors are displayed during save operations but don't prevent saving (warnings only).
-
-## Integration with C++ Battle Simulator
-
-The exported JSON files are designed to be easily consumed by the C++ battle simulator:
-
-1. **Pokemon Data**: Direct mapping to Pokemon class properties
-2. **Move Data**: Complete move information for battle calculations
-3. **Type Effectiveness**: Lookup table for damage calculations
-4. **Consistent IDs**: All data uses consistent Pokemon and move IDs
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Network Errors**: The tool retries failed requests automatically
-2. **Rate Limiting**: Built-in delays prevent API rate limiting
-3. **Memory Usage**: Large downloads are processed in batches
-4. **Validation Warnings**: Usually safe to ignore, indicate minor data inconsistencies
-
-### Getting Help
-
-- Run tests: `python tools/data/test_downloader.py`
-- Check logs: The tool provides detailed logging for debugging
-- Validate data: Use `--no-validation` flag if validation is too strict
-
-## Contributing
-
-To extend the downloader:
-
-1. Add new data structures to `pokemon_downloader.py`
-2. Update validation schemas in `schemas.py`  
-3. Add tests to `test_downloader.py`
-4. Update this documentation
-
-## License
-
-This tool is part of the Pokemon Battle Simulator project and follows the same license terms.
+- Some Pokemon and moves appear in multiple generations
+- Type effectiveness is consistent across generations in the base game
+- The tool respects the PokeAPI fair use policy
+- Data is cached locally to avoid repeated API calls
+- `all_moves.json` contains the complete moves database for efficient filtering
