feat: implement Expected Value System with ICM probability calculator 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>

Add oxlint linting setup with zero errors (#194) * Add oxlint and fix all lint errors - Install oxlint, add .oxlintrc.json with rules for TypeScript/React - Add npm run lint / lint:fix scripts - Add Claude PostToolUse hook to run oxlint on every edited file - Fix 101 errors: unused vars/imports, eqeqeq, prefer-const, no-new-array - Fix no-array-index-key (use stable keys or suppress positional cases) - Fix exhaustive-deps missing dependency in useEffect - Promote exhaustive-deps and no-array-index-key to errors - Fix Map.get() !== null bug in $leagueId.server.ts (should be !== undefined) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Fix no-explicit-any warnings and upgrade tsconfig to ES2023 - Replace all `any` types with proper types or `unknown` across ~20 files - Add typed socket payload interfaces in draft route and useDraftSocket - Use any[] with eslint-disable for socket.io callbacks (legitimate escape hatch) - Bump all tsconfigs from ES2022 → ES2023 to support toSorted/toReversed - Fix cascading type errors uncovered by removing any: Map.get narrowing, participant relation types, ChartDataPoint, Partial<NewSeason> indexing - Add ParticipantResultWithParticipant type to participant-result model - Fix test fixtures to match updated interfaces (DraftCell, ParticipantResult) - Fix duplicate getQPStandings import in sportsSeasonId.server.ts Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Promote no-explicit-any to error Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
