185-189: Strategic placement of block production monitor.The placement of the monitor before any transactions is well-thought-out, allowing for quick detection of consensus failures during genesis. The comment clearly explains why it's not part of the error group.
Consider enhancing the monitoring setup with:
- Error logging strategy
- Graceful shutdown handling
- go monitorBlockProductionExit(ctx, conf) + go func() { + if err := monitorBlockProductionExit(ctx, conf); err != nil { + logger.Error("Block production monitor failed: %v", err) + cancel() // Trigger graceful shutdown + } + }()
185-189: Well-architected placement for resource optimization.The monitor's placement before resource-intensive operations (emissions pool funding, keygen, TSS setup) ensures optimal resource utilization by failing fast on consensus issues. This prevents partial or inconsistent state in the test environment.

185-189: Verify monitor implementation details.
Please ensure that monitorBlockProductionExit properly:
- Respects context cancellation
- Has appropriate timeout mechanisms
- Implements robust error handling
✅ Verification successful
Let me gather more information about the monitor implementation to verify its robustness.
Monitor implementation is robust and well-structured
The implementation demonstrates production-grade practices with:
- Proper context cancellation handling via
<-ctx.Done() - Clear timeout mechanism using
time.After(4 * time.Second) - Comprehensive error handling for RPC client setup, WebSocket events, and block monitoring
- Clean shutdown through context cancellation
- Appropriate error propagation with detailed error messages
The monitor successfully fulfills its role of detecting consensus failures by exiting when blocks aren't produced within the expected timeframe.

Description
The block production monitor should cause the e2e tests to fail fast even if consensus fails immediately at genesis.
