just renamed to server, because it's not HTTP only since it allows websockets and also the package is API so it makes it api.Server which makes more sense.

Effective use of concurrency for the bootstrap process.
The goroutine for running the bootstrap process is well-implemented, using a channel to signal readiness, which synchronizes with the main function. This approach enhances modularity and responsiveness. Ensure that error handling is robust and consider logging the error before panicking to aid in debugging.
Consider adding logging before panicking on bootstrap errors:
- panic(err)
+ logger.Error("Bootstrap failed:", err)
+ panic(err)Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Improved test synchronization with bootstrap process.
The modification to use a readiness channel in Test_ConcurrentTransactionSubmission enhances test reliability by ensuring the bootstrap process is fully ready before proceeding. This change helps avoid race conditions. Consider adding error handling for the goroutine running the bootstrap process to enhance test robustness.
Add error handling for the bootstrap process within the test:
- require.NoError(t, err)
+ if err != nil {
+ t.Errorf("Bootstrap failed: %v", err)
+ return
+ }Committable suggestion

Consistent improvement in test setup.
The use of a readiness channel in Test_CloudKMSConcurrentTransactionSubmission mirrors the improvements made in the other test function, standardizing the approach and enhancing reliability. Similar to the previous test, consider adding error handling for the bootstrap process to ensure test robustness.

Enhanced control flow in test setup.
The introduction of a readiness channel in servicesSetup improves the reliability of tests by ensuring the bootstrap process is fully completed before proceeding. This modification enhances the control flow and reduces potential timing issues. Consider adding error handling for the bootstrap process to ensure robustness.
Add error handling for the bootstrap process within the test setup:
- require.NoError(t, err)
+ if err != nil {
+ logger.Error("Bootstrap failed:", err)
+ return
+ }Committable suggestion was skipped due to low confidence.
