[WIP] Add chess championship orchestration framework

[Copilot]

• Create chess_tournament/championship/__init__.py with exports
• Create chess_tournament/championship/config.py with ChampionshipConfig and setup_logging
• Create chess_tournament/championship/validator.py with SubmissionValidator
• Create chess_tournament/championship/runner.py with TournamentRunner
• Create chess_tournament/championship/leaderboard.py with LeaderboardGenerator
• Create chess_tournament/championship/orchestrator.py with ChessChampionship

Original prompt

Add chess championship orchestration framework

Overview

Add a new championship module to the chess_exam package that provides clean, modular tools for running multi-stage chess tournaments with student submissions.

Features

• ChampionshipConfig: Centralized configuration management with Google Colab support
• SubmissionValidator: Validate student submissions using the existing validate_player function
• TournamentRunner: Execute Swiss and round-robin tournament stages
• LeaderboardGenerator: Generate readable Markdown leaderboards with tie-breaking rules
• ChessChampionship: Main orchestrator that coordinates all stages (Qualifiers → Semifinals → Finals)

Implementation Details

New Module Structure

chess_exam/chess_tournament/championship/
├── __init__.py          (exports all public classes)
├── config.py            (ChampionshipConfig, setup_logging)
├── validator.py         (SubmissionValidator)
├── runner.py            (TournamentRunner)
├── leaderboard.py       (LeaderboardGenerator)
└── orchestrator.py      (ChessChampionship - main class)

Key Features

• Modular design: Each component has a single responsibility
• Google Colab integration: Auto-detects mounted Google Drive for output
• Resumable tournaments: All state saved to CSV files
• Clean logging: Both file and console output with timestamps
• Tournament stages:
  • Qualifiers: Swiss format with groups
  • Semifinals: Swiss format with top qualifiers
  • Finals: Can use round-robin for final leaderboard
• Tie-breaking: Points → Buchholz → Fallbacks (integrates with existing swiss_tournament function)
• Player management: Uses existing instantiate_participant and destroy_instance from chess_exam

Integration Points

• Uses validate_player() from chess_tournament.validate
• Uses swiss_tournament() and round_robin_tournament() from chess_tournament.tournament
• Uses instantiate_participant() and destroy_instance() from chess_tournament.tournament
• Depends on pandas, numpy for data handling

Usage Example

from chess_tournament import RandomPlayer, EnginePlayer
from championship import ChessChampionship, ChampionshipConfig
import pandas as pd

# Define baseline players
baselines = {
    "random": {"name": "Random", "factory": lambda: RandomPlayer("Random")},
    "stockfish": {"name": "Stockfish", "factory": lambda: EnginePlayer("Stockfish")}
}

# Load submissions
submissions_df = pd.read_csv("submissions.csv")

# Run championship
config = ChampionshipConfig()
championship = ChessChampionship(config, baselines)
results = championship.run(submissions_df)

Files to Add

1. chess_tournament/championship/__init__.py - Package init with exports
2. chess_tournament/championship/config.py - Configuration classes
3. chess_tournament/championship/validator.py - Submission validation
4. chess_tournament/championship/runner.py - Tournament execution
5. chess_tournament/championship/leaderboard.py - Output generation
6. chess_tournament/championship/orchestrator.py - Main coordinator

Testing

• Integrates with existing tournament functions (no modifications to existing code)
• Uses existing validate_player for validation
• Compatible with all existing Player classes
• Works on both local and Google Colab environments
