Production Readiness Checklist

Week 4 Integration Testing - Phase 4

Date: October 24, 2025 Version: 20251024.00:00 Status: Ready for Week 5 (Production Launch Prep)

Executive Summary

This checklist validates that CodeSlick's B2B SaaS infrastructure is ready for production deployment. All critical systems (billing, usage limits, team management) have been implemented, tested, and benchmarked.

Overall Status: ✅ PASS (45/47 items complete, 2 pending Week 5)

1. Database & Infrastructure

Schema & Migrations

  • Database schema complete (6 core tables)
  • teams, users, team_members, subscriptions, invoices, audit_logs
  • Foreign key constraints configured (cascade deletes)
  • Indexes created for performance
  • idx_analysis_records_team_analyzed (quota queries)
  • idx_subscriptions_team (billing lookups)
  • idx_invoices_team_created (invoice history)
  • idx_team_members_team (member listings)
  • stripe_customer_id column added to teams table
  • Migration tested (drizzle-kit push verified)
  • Rollback plan documented (schema snapshots available)

Database Performance

  • Quota check < 50ms (target: 50ms, actual: ~20ms)
  • Team lookup < 20ms (target: 20ms, actual: ~5ms)
  • Member list < 100ms (target: 100ms, actual: ~15ms)
  • Analytics queries < 500ms (all endpoints tested)
  • Connection pooling configured (Neon Serverless Driver)

Backup & Recovery

  • Automated daily backups (Neon platform default)
  • Point-in-time recovery available (7-day retention)
  • Disaster recovery plan documented ⚠️ PENDING WEEK 5
  • Data retention policy defined (90 days for audit logs)

2. Billing & Payments (Stripe)

Stripe Integration

  • Test mode functional (all flows tested)
  • Checkout session creation (< 2000ms)
  • Webhook signature verification (security validated)
  • Customer portal integration (< 1000ms)
  • 5 critical events handled:
  • checkout.session.completed
  • customer.subscription.updated
  • customer.subscription.deleted
  • invoice.paid
  • invoice.payment_failed
  • Idempotent webhook processing (safe retries)
  • Audit logging for all billing events

Payment Flows

  • FREE → TEAM upgrade flow (end-to-end tested)
  • FREE → ENTERPRISE upgrade flow (end-to-end tested)
  • Subscription cancellation flow (downgrades to FREE)
  • Payment failure handling (grace period + notifications)
  • Invoice generation (stored in database + Stripe URLs)
  • Refund handling (manual via Stripe Dashboard)

Pricing Configuration

  • FREE plan limits (20 analyses/month, 1 repo)
  • TEAM plan pricing (€99/month, unlimited analyses)
  • ENTERPRISE plan pricing (€299/month, unlimited everything)
  • Stripe products created (test mode)
  • Production Stripe keys configured ⚠️ PENDING WEEK 5

3. Usage Limits & Enforcement

Quota System

  • Plan-based limits enforced (FREE: 20, TEAM/ENT: unlimited)
  • 3-day grace period (for FREE tier over-quota)
  • Monthly quota reset (first of month)
  • Approaching limit warnings (80% threshold)
  • Quota exceeded modal (upgrade prompt)
  • Audit logging for quota events

Enforcement Points

  • Analysis API protected (quota check before analysis)
  • GitHub webhook protected (quota check before PR analysis)
  • Dashboard displays quota (usage vs. limit)
  • Concurrent quota checks handled (race conditions tested)

Edge Cases

  • Plan upgrade immediately reflects (quota goes unlimited)
  • Plan downgrade enforces limits (grace period activated)
  • Grace period expiration blocks (analysis rejected)
  • Monthly reset clears quota (starts fresh)

4. Team Management & Settings

Team CRUD Operations

  • Team creation (owner, slug, plan)
  • Team name update (validation, slug auto-gen)
  • Team slug update (uniqueness check, format validation)
  • Team deletion (cascade deletes, Stripe cancellation)

Member Management

  • Add member (auto-creates user if needed)
  • Remove member (prevents removing last owner)
  • Role assignment (owner, admin, member)
  • Duplicate prevention (unique user per team)
  • Audit logging (all member changes tracked)

Settings Interface

  • General settings tab (name, slug, plan display)
  • Members settings tab (invite, remove, roles)
  • Billing settings tab (current plan, upgrade cards, portal)
  • Danger zone tab (team deletion with confirmation)

Permissions & Access Control

12. Risk Assessment

High Priority Risks (Mitigated)

Risk Mitigation Status
Webhook reliability Idempotency, retry logic, audit logs ✅ Mitigated
Usage limit bypass Middleware enforcement, audit logs ✅ Mitigated
Payment failures Grace period, notifications, portal ✅ Mitigated
Data loss Automated backups, cascade deletes tested ✅ Mitigated
Performance degradation Indexes, caching, benchmarks ✅ Mitigated

Medium Priority Risks (Acceptable)

Risk Impact Mitigation Plan
Stripe API downtime Users can't upgrade Show maintenance message, retry
Database connection issues Queries fail Connection pooling, error handling
Concurrent team operations Race conditions Database transactions, optimistic locking

Low Priority Risks (Monitored)

Risk Impact Action
Test mode confusion Wrong Stripe keys Clear env var naming, UI indicators
Email delivery failures Notifications missed Queue retries, manual fallback
Large dataset performance Slow queries Pagination, query optimization
