- Add cross-node transaction testing workflow (manual dispatch) - Add node failover simulation workflow (manual dispatch, check logic only) - Add multi-node stress testing workflow (manual dispatch) - All workflows use only RPC endpoints (no SSH access) - All workflows run on manual dispatch only - No remediation steps (monitoring/testing only) - Cross-node transaction testing uses real transactions from test wallet - Failover simulation uses check logic only (no actual shutdown) - Stress testing generates real transactions with configurable count/rate - Comprehensive logging to /var/log/aitbc/ - Proper wallet creation and cleanup
