Phase 3 Integration - Progress Report

Date: 2026-07-12
Status: ✅ Client Services Updated, UI Integration Next

---

✅ COMPLETED: Client Stats Service Updates

1. Updated stats-service.ts (OpenSkill Integration)

Changes:

• ✅ Replaced Elo imports with OpenSkill functions from warp12-engine
• ✅ Updated incrementLocalAiSkillStats() to use OpenSkill rating updates
• ✅ Updated previewLocalAiMatchReport() to use TEI grade system
• ✅ Updated displayPlayerObjectiveTei() to return TEI score (0-99)
• ✅ Added getPlayerTeiDisplay() - returns full TEI display (grade + score)
• ✅ Added getPlayerStoredRating() - returns complete rating with displayGrade
• ✅ Fixed academy placement functions to use new schema

Key Functions:

// Legacy (returns just score for backward compatibility)
displayPlayerObjectiveTei(stats, skill, objective): number | null

// New TEI display (returns {grade, score, formatted})
getPlayerTeiDisplay(stats, skill, objective): TeiDisplay | null

// Get full rating object with hysteresis grade
getPlayerStoredRating(stats, skill, objective): StoredRating | null

2. Updated use-player-stats.ts Hook

Changes:

• ✅ Added getTeiDisplay() method to hook interface
• ✅ Added getStoredRating() method to hook interface
• ✅ Imported TEI types from warp12-engine
• ✅ All existing functions still work (backward compatible)

Usage:

const playerStats = usePlayerStats();

// Legacy: Get numeric score only
const score = playerStats.displayTei('commander', 'points'); // → 67

// New: Get full TEI display
const tei = playerStats.getTeiDisplay('commander', 'points'); 
// → { grade: 'V', score: 67, formatted: 'V67' }

// Get rating with hysteresis grade
const rating = playerStats.getStoredRating('commander', 'points');
// → { mu: 32.0, sigma: 1.2, matches: 150, displayRating: 28.4, displayGrade: 'V' }

📊 What Works Now

1. Client can read ratings from Firestore with displayGrade
2. Client can calculate TEI displays with hysteresis
3. Preview functionality shows TEI changes before/after matches
4. Hooks expose TEI data to React components

🎯 NEXT STEPS: UI Integration

Step 1: Profile Page

File: apps/Warp12/src/app/profile-page.tsx

Tasks:

• Import TeiDisplay component
• Replace old TEI display with <TeiDisplay />
• Show both Go-Out and Points ratings
• Add tooltip showing raw μ/σ for power users
• Optional: Add “Advanced Stats” toggle

Example:

import { TeiDisplay } from './components/tei-display';

const tei = playerStats.getTeiDisplay('commander', 'points');
const rating = playerStats.getStoredRating('commander', 'points');

<TeiDisplay
  rating={rating}
  currentGrade={rating?.displayGrade}
  objective="points"
  size="large"
/>

Step 2: Leaderboard Page

File: apps/Warp12/src/app/leaderboard-page.tsx

Tasks:

• Import TeiGradeBadge component
• Use badges in table rows
• Sort by displayRating
• Optional: Use TeiDisplay for detailed view

Example:

import { TeiGradeBadge } from './components/tei-grade-badge';

<TeiGradeBadge
  grade={entry.displayGrade}
  size="small"
/>

Step 3: Match Summary Page

File: apps/Warp12/src/app/sector-summary.tsx

Tasks:

• Import TeiChange component
• Show before → after rating with animation
• Celebrate grade promotions (I→C, C→V, etc.)

Example:

import { TeiChange } from './components/tei-change';

<TeiChange
  before={beforeRating}
  after={afterRating}
  objective="points"
/>

Step 4: In-Game HUD (Optional)

Tasks:

• Use <TeiGradeBadge /> next to player names
• Keep it minimal (just letter badge)

🧪 Testing Checklist

Before deploying:

Local Testing:

• Build all packages: yarn build:all
• Run tests: yarn test:all
• Test profile page displays TEI correctly
• Test leaderboard sorting works
• Test match summary shows rating changes
• Verify hysteresis prevents flickering

Integration Testing:

• Play local AI match → verify TEI updates
• Play multiple matches → verify hysteresis (no flicker at boundaries)
• Test academy placement flow
• Check tooltips show μ/σ correctly

🚀 Deployment Plan

After UI integration is complete:

1. Build everything:

   yarn build:all
   yarn build:all:hosting
   

2. Wipe Firebase (user confirmed safe):
   • Delete playerStats collection
   • Delete ratedMatches collection
   • Delete publishedLogs collection
3. Deploy:

   yarn deploy:firestore  # Rules
   yarn deploy:functions  # Cloud Functions
   yarn deploy:hosting    # Web app + leaderboard
   

4. Verify:
   • Play test match
   • Check rating updates
   • Verify hysteresis works
   • Check leaderboard sorting

💡 Key Design Decisions

1. Backward Compatibility:
   • displayPlayerObjectiveTei() still returns numeric score
   • New functions added without breaking existing code
   • Gradual migration path for UI components
2. Hysteresis Integration:
   • displayGrade stored in Firestore
   • Always passed to getTeiDisplay() for consistency
   • UI components accept currentGrade prop
3. Three-Layer API:
   • Score only: displayPlayerObjectiveTei() → number
   • Full display: getPlayerTeiDisplay() → {grade, score, formatted}
   • Raw rating: getPlayerStoredRating() → StoredRating with displayGrade
