PRD Validation Report - WagerBabe Generated: January 13, 2025

Current Project Status: 80% Complete Purpose: Validate PRD accuracy against actual implementation state --- ## Executive Summary The PRD was created when the project was at ~5% capacity (50 concurrent users). Since then, Phase 1 Weeks 1-2 have been COMPLETED, achieving 20x performance improvement to support 10,000-15,000 concurrent users. The PRD needs updates to reflect this progress and clarify remaining work. ### Key Findings GOOD: PRD correctly identifies database crisis (97.4% capacity - URGENT) GOOD: PRD architecture, tech stack, and requirements are accurate OUTDATED: Baseline capacity numbers (50 -> 10,000-15,000 users) OUTDATED: Phase 1 progress (Weeks 1-2 COMPLETE, not pending) MINOR: Python version (3.8+ should be 3.11+ or 3.13) --- ## Detailed Validation ### 1. Capacity Baseline - OUTDATED PRD States (Line 721):

"Current capacity: ~50 concurrent users, database at 97.4% full" ACTUAL Current State:

  • Capacity: 10,000-15,000 concurrent users
  • Database: Still at 97.4% (archival urgently needed)
  • Performance: 20x improvement achieved through Redis + connection pooling Evidence:
  • docs/architecture.md Section 4.1: "Achieved (Phase 1 - Week 2 COMPLETE): Concurrent User Capacity: 10,000-15,000 users"
  • docs/architecture/SCALABILITY_ASSESSMENT.md Line 9: "Current System Capacity: 10,000 - 15,000 Concurrent Users" Recommendation: Update PRD to reflect 10k-15k baseline capacity, keeping database crisis as primary constraint. --- ### 2. Phase 1 Progress - UNDERSTATED PRD States (Lines 146-172):

Week 1: Database & Sidebar Optimization Week 2: Tiered Caching & API Efficiency ACTUAL Current State:

  • Week 1 COMPLETE: Database connection pooling (asyncpg 10-50 connections)
  • Week 2 COMPLETE: Redis caching (HOT/WARM/COLD strategies, 95%+ hit ratio)
  • ⏳ Week 3 IN PROGRESS: Database archival (97.4% -> <70%)
  • ⏳ Week 4 PENDING: Query optimization, virtual scrolling, load testing Evidence:
  • docs/architecture.md Section 4.1: "Achieved (Phase 1 - Week 2 COMPLETE)"
  • docs/architecture/SCALABILITY_ASSESSMENT.md Line 488: "Phase 1: Foundation (Weeks 1-4) - 50% COMPLETE" Recommendation: Mark Phase 1 Weeks 1-2 as COMPLETE in PRD, clarify Weeks 3-4 are current focus. --- ### 3. Technology Stack - MOSTLY ACCURATE PRD Tech Stack vs Reality: | Component | PRD States | Actual | Status | |-----------|------------|--------|--------| | Frontend | Next.js 15 + React 19 | Next.js 15.4.5 + React 19.1.0 | Correct | | Backend | FastAPI (Python 3.8+) | FastAPI 0.104.1 (Python 3.13) | Minor (3.8+ -> 3.13) | | Database | PostgreSQL via Supabase | PostgreSQL via Supabase | Correct | | Cache | Redis | Redis 5.0.1 with hiredis | Correct | | Deployment | Railway + Supabase | Railway + Supabase | Correct | | Auth | JWT with Supabase | JWT + Better Auth | Correct (Better Auth added) | Recommendation: Update Python version requirement to 3.11+ (or specify 3.13 explicitly). --- ### 4.

  • Expected Impact: 70-80% capacity reduction (97.4% -> <70%)
  • Status: Documented in architecture.md as Week 3 priority
  • PRD Alignment: Correctly identified in PRD ### HIGH PRIORITY (Week 3-4) 2. Sidebar Materialized Views (FR69)
  • Issue: Sidebar target is <100ms, needs optimization
  • Solution: Create materialized views for sports/league aggregation
  • Status: Documented in architecture.md
  • PRD Alignment: Correctly identified in PRD 3. Load Testing (NFR-O4-O6)
  • Issue: 10k-15k capacity achieved but not validated under load
  • Solution: Automated load tests at 1.5x peak (15k users)
  • Status: Week 4 priority in architecture.md
  • PRD Alignment: Correctly identified in PRD ### ℹ MEDIUM PRIORITY (Phase 2) 4. Mobile Performance Validation (NFR-P1-P5)
  • Issue: Lighthouse Mobile Score >90 target not validated
  • Solution: Run Lighthouse CI, optimize bundle size
  • Status: Tools exist (package.json has lighthouse scripts)
  • PRD Alignment: Correctly identified in PRD 5. Offline Capability (FR57)
  • Issue: PWA service worker for offline viewing
  • Solution: next-pwa configured but needs implementation
  • Status: Deferred to Phase 2 (not critical for launch)
  • PRD Alignment: Correctly marked as Phase 2+ --- ## Recommendations ### 1. Update PRD Baseline Metrics Current PRD Statement:

"Current capacity: ~50 concurrent users, database at 97.4% full" Recommended Update: "Achieved Capacity (Phase 1 Week 2): 10,000-15,000 concurrent users (20x improvement) Current Constraint: Database at 97.4% capacity (archival urgently needed) Remaining Phase 1 Work: Database archival (Week 3), query optimization (Week 3-4), load testing (Week 4)" ### 2.

1. Review this validation report
2. Decide if PRD updates are needed now or can wait until Phase 1 complete
3. Confirm Week 3-4 priorities align with business goals **For Development:**
1. **Week 3 PRIORITY:** Database archival implementation (FR63-FR64)
