OpenSkill + TEI Grade Deployment Checklist

Date: 2026-07-12
Migration: Elo → OpenSkill with TEI Grades

✅ PRE-DEPLOYMENT VERIFICATION

Build Status

  • Engine builds: ✅ yarn build:engine passes
  • Engine tests: ✅ 62/62 tests passing
  • Functions build: ✅ npm run build passes in functions/
  • No TypeScript errors: ✅ All files compile cleanly

Code Changes Verified

  • Backend: Cloud Functions use OpenSkill + calculate displayGrade
  • Client: stats-service.ts updated to OpenSkill
  • Schema: displayGrade added to StoredRating
  • Hysteresis: Implemented in TEI grade calculation
  • UI Components: Created and ready (TeiDisplay, TeiChange, TeiGradeBadge)

📋 DEPLOYMENT STEPS

Step 1: Pre-Deployment Backup

What to backup:

  • Current Firestore rules: firestore.rules
  • Current Cloud Functions: Download from Firebase Console

How to backup:

# Backup rules
cp firestore.rules firestore.rules.backup

# Backup functions (already in Git)
git log --oneline -5 functions/

Note: User confirmed safe to wipe all data, but backup anyway for safety.

Step 2: Build Everything

cd /Volumes/Code/Warp12

# Build engine (warp12-engine)
yarn build:engine

# Build all packages
yarn build:all

# Build hosting (if deploying web app)
yarn build:all:hosting

# Verify builds succeeded
echo "✅ Builds complete"

Expected output:

  • Engine: ✓ built in ~1s
  • No TypeScript errors
  • All packages compile successfully

Step 3: Wipe Firebase Collections

⚠️ CRITICAL: User confirmed this is safe (no production data)

Collections to delete:

  1. playerStats - All player rating data
  2. ratedMatches - All rated match records
  3. publishedLogs - Optional (for clean slate)

Option A: Firebase Console (Recommended)

  1. Go to https://console.firebase.google.com
  2. Select project: warp-12
  3. Navigate to Firestore Database
  4. For each collection:
    • Click collection name
    • Click “Delete collection”
    • Confirm deletion

Option B: Firebase CLI

# Install Firebase CLI if needed
npm install -g firebase-tools

# Login
firebase login

# Delete collections
firebase firestore:delete playerStats --project warp-12 --recursive -y
firebase firestore:delete ratedMatches --project warp-12 --recursive -y
firebase firestore:delete publishedLogs --project warp-12 --recursive -y

echo "✅ Collections wiped"

Verification:

  • playerStats collection empty or deleted
  • ratedMatches collection empty or deleted
  • publishedLogs collection empty or deleted

Step 4: Deploy Firestore Rules

cd /Volumes/Code/Warp12

# Deploy security rules (updated humanTei → humanRating)
yarn deploy:firestore

# Or directly:
# firebase deploy --only firestore:rules --project warp-12

What this deploys:

  • Updated security rules with humanRating instead of humanTei
  • Rules support new schema with displayGrade field

Expected output:

✔ Deploy complete!

Verification:

  • No deployment errors
  • Rules updated in Firebase Console

Step 5: Deploy Cloud Functions

cd /Volumes/Code/Warp12

# Deploy all functions
yarn deploy:functions

# Or deploy specific functions:
# firebase deploy --only functions:reportPracticeAiMatch --project warp-12
# firebase deploy --only functions:reportOnlineMatch --project warp-12
# firebase deploy --only functions:setAcademyPlacement --project warp-12

What this deploys:

  • reportPracticeAiMatch - Solo vs AI rating updates
  • reportOnlineMatch - Online multiplayer rating updates
  • setAcademyPlacement - Academy placement
  • applyHumanTei - (internal) Human rating updates
  • applyGroupTei - (internal) Charter/crew rating updates
  • Other supporting functions

Expected output:

✔ functions[...]: Successful update operation
✔ Deploy complete!

Verification:

  • No deployment errors
  • All functions deployed successfully
  • Check Firebase Console → Functions → all listed

Step 6: Deploy Hosting (Optional)

Only if deploying web app:

cd /Volumes/Code/Warp12

# Deploy hosting
yarn deploy:hosting

# Or separately:
# firebase deploy --only hosting:Warp12 --project warp-12
# firebase deploy --only hosting:leaderboard --project warp-12

What this deploys:

  • Main web app (The Bridge)
  • Leaderboard SPA (optional)

Expected output:

✔ hosting[Warp12]: Deploy complete
✔ Deploy complete!

Step 7: Post-Deployment Verification

7.1 Test Solo vs AI Match

  1. Open app (locally or deployed)
  2. Sign in (anonymous auth)
  3. Start solo match vs AI (Commander, Points objective)
  4. Complete match (win or lose)
  5. Check Firestore:
    playerStats/{uid}/localAi/commander/points

    Expected data:

    {
  "rating": {
    "mu": 25.5,           // ← Should be ~25 for new player
    "sigma": 7.8,         // ← Should decrease from 8.33
    "matches": 1,
    "displayRating": 2.1, // ← μ - 3σ
    "displayGrade": "P"   // ← Should be "P" (Provisional)
  },
  "wins": 1               // ← 1 if won, 0 if lost
}
  6. Verify in UI:
    • Profile page shows TEI (numeric or badge)
    • No errors in console
    • Rating updates correctly

Checklist:

  • Match completes without errors
  • Firestore document created
  • displayGrade field present
  • Rating values reasonable (μ ≈ 25-30, σ < 8.33)
  • UI displays rating correctly

7.2 Test Hysteresis (Play Multiple Matches)

  1. Play 10-15 matches vs same AI opponent
  2. Watch σ decrease (should go from ~8.33 → ~3.0)
  3. Watch grade evolve:
    • Start: P (σ ≥ 4.0)
    • After 5-8 games: I (2.5 ≤ σ < 4.0)
    • After 15+ games: C (1.5 ≤ σ < 2.5)
  4. Verify no flickering:
    • At σ ≈ 4.0, should NOT flicker between I ↔ P
    • At σ ≈ 2.5, should NOT flicker between C ↔ I
    • Grade should be stable for several matches

Checklist:

  • σ decreases with more matches
  • Grade progresses: P → I → C
  • No flickering at boundaries
  • displayGrade updates correctly in Firestore

7.3 Test Online Match (If Available)

  1. Host rated sector (Warp 12, Points objective)
  2. Complete match with human players
  3. Report match (host calls reportOnlineMatch)
  4. Check Firestore:
    playerStats/{uid}/humanRating/points

Expected data:

{
  "rating": {
    "mu": 25.0,
    "sigma": 8.33,
    "matches": 1,
    "displayRating": 0.0,
    "displayGrade": "P"
  },
  "wins": 1
}

Checklist:

  • Online match rating updates
  • humanRating field populated
  • displayGrade present
  • No errors in function logs

7.4 Monitor Function Logs

# Watch real-time logs
firebase functions:log --project warp-12

# Or in Firebase Console:
# Functions → Logs → Filter by function name

Look for:

  • ✅ Successful rating updates
  • ✅ No errors or warnings
  • ✅ Reasonable execution times (<1s)

Red flags:

  • ❌ TypeError or undefined errors
  • ❌ Schema validation failures
  • ❌ Rating calculation errors

🚨 ROLLBACK PLAN

If something goes wrong:

Quick Rollback (Functions Only)

# Revert to previous functions deployment
firebase functions:config:rollback --project warp-12

Full Rollback (Functions + Rules)

# 1. Restore old rules
cp firestore.rules.backup firestore.rules
firebase deploy --only firestore:rules --project warp-12

# 2. Revert code changes
git log --oneline -10
git revert <commit-hash>
git push

# 3. Redeploy old functions
cd functions
npm run build
firebase deploy --only functions --project warp-12

Nuclear Option (Restore from Git)

# Find last known-good commit
git log --oneline --all | grep -i "elo"

# Reset to that commit
git reset --hard <commit-hash>

# Force push (if needed)
git push --force

# Redeploy
yarn build:all
yarn deploy:firebase

✅ POST-DEPLOYMENT CHECKLIST

📊 SUCCESS METRICS

Technical Metrics

  • ✅ 100% of matches result in rating updates
  • ✅ 0 function errors per 1000 matches
  • ✅ Average function execution time < 500ms
  • ✅ No boundary flickering observed

User Experience Metrics

  • ✅ Ratings feel “smoother” (no wild swings)
  • ✅ Grade progression feels fair
  • ✅ Hysteresis prevents frustrating flickers
  • ✅ “V67” format is more engaging than “1532”

📝 NOTES

What’s Backward Compatible

  • ✅ Old stats-service functions still work (displayPlayerObjectiveTei)
  • ✅ Existing UI doesn’t break (still shows numbers)
  • ✅ Old match history preserved (teiBefore/teiAfter still work)

What’s NOT Backward Compatible

  • ❌ Old Elo ratings → OpenSkill ratings (requires wipe)
  • ❌ Old schema (humanTei) → new schema (humanRating)
  • ❌ Firestore queries need to use new field names

Migration Notes

  • User confirmed: No production users, safe to wipe all data
  • No migration script needed: Clean slate deployment
  • Old data: Will be deleted, not converted
