Implements Phase 5.2 of the EV system with Harville-Malmuth Independent Chip Model for calculating participant placement probabilities from futures odds. ## Key Features ### ICM Probability Calculator - Implements Harville-Malmuth method for distributing probabilities - Converts American odds to championship probabilities - Generates P(1st) through P(8th) for all participants - Column-normalized: each placement sums to 100% across all teams - Works with any number of participants (not limited to 8) ### Admin UI - Futures Odds Entry - Enter American odds (e.g., +550, -200) for championship futures - Live preview of ICM-calculated probability distributions - Displays all 8 placement probabilities - Persists odds for editing on subsequent visits - Automatic probability normalization (removes bookmaker vig) ### Database Schema Updates - Renamed participant_expected_values.season_id → sports_season_id - Updated foreign key to reference sports_seasons instead of seasons - Added source_odds field to store original futures odds - Migration 0025: Column rename and FK update - Migration 0026: Add source_odds field ### Model Layer - participant-expected-value: CRUD operations for probability distributions - Supports multiple probability sources (manual, futures_odds, elo_simulation) - Automatic EV calculation based on league scoring rules - Probability validation and normalization ### Service Layer - icm-calculator: Harville-Malmuth probability distribution - probability-engine: Odds conversion and Elo utilities (for future use) - bracket-simulator: Monte Carlo simulation (for future hybrid approach) - ev-calculator: Expected value computation from probabilities ## Technical Details - Uses exponential decay favoring top positions for strong teams - Preserves championship probability ordering in final distributions - Row sums vary (strong teams ~100%, weak teams lower) - All probabilities between 0-1, mathematically valid - Comprehensive test suite: 97 tests passing ## Future Enhancements - Hybrid approach: ICM pre-playoffs, bracket simulation during playoffs - Integration with league-specific scoring rules - Historical probability tracking for accuracy analysis 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |

Welcome to React Router!
A modern, production-ready template for building full-stack React applications using React Router.
Features
- 🚀 Server-side rendering
- ⚡️ Hot Module Replacement (HMR)
- 📦 Asset bundling and optimization
- 🔄 Data loading and mutations
- 🔒 TypeScript by default
- 🎉 TailwindCSS for styling
- 💾 PostgreSQL + DrizzleORM
- 📖 React Router docs
Getting Started
Installation
Install the dependencies:
npm install
Development
Copy .env.example to .env and provide a DATABASE_URL with your connection string.
Run an initial database migration:
npm run db:migrate
Start the development server with HMR:
npm run dev
Your application will be available at http://localhost:5173.
Building for Production
Create a production build:
npm run build
Deployment
Docker Deployment
To build and run using Docker:
# For npm
docker build -t my-app .
# Run the container
docker run -p 3000:3000 my-app
The containerized application can be deployed to any platform that supports Docker, including:
- AWS ECS
- Google Cloud Run
- Azure Container Apps
- Digital Ocean App Platform
- Fly.io
- Railway
DIY Deployment
If you're familiar with deploying Node applications, the built-in app server is production-ready.
Make sure to deploy the output of npm run build
