PR Review: fix(node/tests): fix kurtosis ci

Reviewing changes that pin Teku consensus client version and downgrade Kurtosis CLI to fix CI issues.

Review Tasks:

• Analyze mise.toml Kurtosis CLI downgrade
• Review devnet YAML configuration changes
• Assess version pinning strategy and approach
• Check for consistency across all devnet configs
• Evaluate potential impact on CI stability
• Provide overall feedback and recommendations

Review Feedback

✅ Code Quality & Best Practices

Positive aspects:

• Consistent approach: The Teku version pin (consensys/teku:25.7.1) is applied uniformly across all 9 devnet configurations
• Targeted fix: Changes are minimal and focused specifically on the CI stability issue
• Backwards compatibility: Version downgrades are generally safer than upgrades for CI stability

Areas for improvement:

• Missing line termination: Both modified files lack proper line endings (mise.toml:3 and YAML files)
• Documentation: Consider adding a comment in mise.toml explaining why the Kurtosis CLI version is pinned to 1.8.1

⚠️ Potential Issues

1. Version drift concern: The dual version pinning approach (Kurtosis CLI downgrade + Teku pin) creates technical debt:

   • Kurtosis CLI: 1.10.3 → 1.8.1 (significant downgrade)
   • Risk of missing important bug fixes and features in newer Kurtosis versions
   • Should document when these pins can be updated

2. Implicit dependencies: The relationship between Kurtosis CLI version and Teku compatibility isn't documented

   • Future maintainers may not understand why these specific versions are required

🔒 Security Considerations

• Image provenance: Teku image consensys/teku:25.7.1 appears to be from the official Consensys registry ✅
• Version pinning benefits: Prevents unexpected issues from automatic updates ✅
• Downgrade risk: Using older Kurtosis CLI (1.8.1) may miss security patches - monitor for CVEs

⚡ Performance Considerations

• Version changes are configuration-only with no performance impact
• Older Kurtosis CLI may have performance regressions, but stability takes precedence for CI

🧪 Test Coverage

• Changes affect test infrastructure rather than application code
• All 9 devnet configurations are updated consistently ✅
• Consider adding a test that validates version compatibility

📋 Recommendations

1. Documentation: Add inline comments explaining version choices:

   # Pinned to 1.8.1 due to compatibility issues with Teku 25.7.1 in CI
   "ubi:kurtosis-tech/kurtosis-cli-release-artifacts[exe=kurtosis]" = "1.8.1"

2. File formatting: Add proper line endings to mise.toml

3. Future maintenance: Create a follow-up issue to:

   • Test compatibility with newer Kurtosis CLI versions
   • Establish a regular review cycle for version pins
   • Document the upgrade path

4. CI monitoring: Ensure the fixed CI jobs are monitored for continued stability

🎯 Overall Assessment

This is a well-executed emergency fix that addresses immediate CI stability issues. The approach is conservative and consistent, prioritizing reliability over cutting-edge versions. While it introduces some technical debt through version pinning, this is appropriate for resolving urgent CI failures.

Recommendation: ✅ Approve - The changes effectively address the stated problem with minimal risk.
