Next Immediate Steps

Option A: Monitoring Verification (Recommended - Quick Win)

Time: 2 hours
Why: Last quick gap before scale testing
Deliverable: Verified monitoring stack

Steps:

  1. Deploy Prometheus + Grafana with docker-compose
  2. Import existing dashboards
  3. Generate test metrics
  4. Verify alerting rules
  5. Document monitoring guide

After This: 14/15 (93%), only scale testing remains

Option B: Scale Testing (Long Effort)

Time: 8 hours
Why: Most comprehensive remaining gap
Deliverable: Scale test results

Steps:

  1. Create simulation framework
  2. Set up 100+ node test environment
  3. Run convergence tests
  4. Measure performance under load
  5. Document results

After This: 15/15 (100%) - COMPLETE!

Recommendation

Proceed with Monitoring Verification for these reasons:

  1. Quick Win: 2 hours vs 8 hours
  2. High Value: Critical for production operations
  3. Nearly Done: Gets us to 93% completion
  4. Momentum: Keep the winning streak going

After monitoring, we can tackle scale testing as the final comprehensive gap.
