Creates asymmetric buffer that rewards improvement

Grade Boundaries:

E (Elite): Promote at σ < 0.5, demote at σ > 0.7
V (Veteran): Promote at σ < 1.5, demote at σ > 1.7
C (Consistent): Promote at σ < 2.5, demote at σ > 2.7
I (Improving): Promote at σ < 4.0, demote at σ > 4.5
P (Provisional): σ ≥ 4.0

Tests:

Location: libs/engine/src/lib/rating/tei-grade.spec.ts
40 tests covering all grade transitions
Hysteresis behavior verification
Edge case handling

Deployment Checklist

Future Enhancements (Post-Launch)

These items are not required but could be added based on user feedback:

Leaderboard Advanced View — Requires backend schema changes to expose μ/σ in leaderboard entries. Power-user feature that can be added if requested.
Match Preview — Pre-game “what if” scenarios showing potential rating changes. Needs UX design to avoid over-emphasizing ratings before gameplay.
Additional Storybook Config — Full Nx Storybook integration for live preview server. Stories are written and ready to use.

Conclusion

Phase 3 is complete and production-ready. The OpenSkill rating system has rich, accessible UI/UX that helps users understand and track their progress. All required components are implemented, tested, and documented.

The system provides:

Clear visual communication of rating (grade + score)
Celebration of achievements (confetti on promotions)
Deep insights for engaged users (charts, advanced stats)
Accessibility for all users (WCAG AA)
Developer documentation (Storybook stories)

Module Zeta (team play) can proceed immediately.
