📋 Change Summary

The PR removes a single warning log statement logger().warn("already called onRunnerStart"); from the onRunnerStart method in packages/rivetkit/src/drivers/file-system/global-state.ts:421.

✅ Code Quality & Best Practices

• Positive: The removal is clean and maintains the early return behavior that prevents double initialization
• Positive: The method's logic remains intact - it still prevents multiple calls via the early return guard
• Good: The change follows the codebase's logging guidelines (lowercase messages would be preferred anyway)

🔍 Analysis

Context Understanding:

• The onRunnerStart method is called once during driver initialization (mod.ts:34)
• It has a guard clause that returns early if #runnerParams is already set
• The warning was triggered if the method was called multiple times
• The method is critical for setting up alarm scheduling and actor management

Logic Assessment:

• The early return guard (if (this.#runnerParams) { return; }) provides sufficient protection against double initialization
• The warning served as a diagnostic tool but may have been generating noise in legitimate scenarios

🐛 Potential Issues

• Low Risk: Removing the warning reduces visibility into potential double-initialization attempts
• Consideration: If there were legitimate cases where this method could be called multiple times (e.g., in testing scenarios or certain driver configurations), the warning removal is appropriate

🚀 Performance Considerations

• Positive: Micro-performance improvement by removing a log operation
• Neutral: No significant performance impact overall

🔒 Security Concerns

• None identified: This change doesn't introduce security risks
• The core protection mechanism (early return) remains intact

🧪 Test Coverage

• Recommendation: Ensure tests verify that:
  1. onRunnerStart can be safely called multiple times without side effects
  2. The method properly initializes #runnerParams on first call
  3. Alarm loading functionality still works correctly after initialization
• Note: Without seeing the test files, I cannot assess if such coverage exists

💡 Suggestions

1. Consider adding a debug log: If diagnostic visibility is still desired, consider:

   if (this.#runnerParams) {
     logger().debug("onRunnerStart called multiple times, ignoring");
     return;
   }

2. Documentation: Consider adding a JSDoc comment explaining that multiple calls are safe and intentionally ignored

📊 Overall Assessment

APPROVED ✅ - This is a reasonable change that:

• Removes potentially noisy warning logs
• Maintains all functional safety guarantees
• Follows good logging practices (warnings should indicate actual problems)
• Has minimal risk since the protection mechanism remains intact

The change suggests this warning was either:

• Being triggered in legitimate scenarios where multiple calls are expected
• Determined to be unnecessary noise rather than useful diagnostics
