64-66: Ohayo, sensei! Verify all usages of Sequencing after trait change
Ensure that all instances where Sequencing was used as a Stage are updated to the new IntoFuture implementation to prevent any unexpected behavior.
Here's a script to help verify:
✅ Verification successful
Ohayo, sensei! All clear on the Sequencing front!
The verification shows that the transition from Stage to IntoFuture for Sequencing is clean and complete:
- No remaining
Stageimplementations forSequencingexist - The only usage is in
katana/node/src/lib.rswhereSequencing::newis called, and it's already adapted to work with the newIntoFutureimplementation - No other places in the codebase are trying to use
Sequencingas aStage

131-131: Ohayo, sensei! Ensure consistent removal of Pipeline references
With the elimination of the pipeline abstraction, please verify that all references to Pipeline have been updated to prevent any residual dependencies or inconsistencies.
Here's a script to identify any remaining references:
| fn into_future(self) -> Self::IntoFuture { | ||
| Box::pin(async move { | ||
| // Build the messaging and block production tasks. | ||
| let messaging = self.run_messaging().await.unwrap(); |

Ohayo, sensei! Avoid using unwrap() on run_messaging().await
Using unwrap() may cause a panic if run_messaging() returns an error. It's better to handle the error gracefully to prevent unexpected crashes.
Consider handling the error as follows:
- let messaging = self.run_messaging().await.unwrap();
+ let messaging = match self.run_messaging().await {
+ Ok(handle) => handle,
+ Err(e) => {
+ error!(target: "sequencing", reason = ?e, "Failed to start messaging task.");
+ return;
+ }
+ };📝 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.
| let messaging = self.run_messaging().await.unwrap(); | |
| let messaging = match self.run_messaging().await { | |
| Ok(handle) => handle, | |
| Err(e) => { | |
| error!(target: "sequencing", reason = ?e, "Failed to start messaging task."); | |
| return; | |
| } | |

74-77: Consider adding formal documentation for the infinite task natureThe comment about tasks running forever should be promoted to proper documentation. This is an important architectural detail that should be more visible.
Consider adding this before the struct definition:
+ /// # Task Lifecycle + /// Both messaging and block production tasks are designed to run indefinitely. + /// Any completion of these tasks should be considered an error condition.
79-84: Enhance error logging with more contextThe error logging could provide more detailed diagnostics about the task failure.
Consider enhancing the error messages:
- error!(target: "sequencing", reason = ?res, "Messaging task finished unexpectedly."); + error!( + target: "sequencing", + reason = ?res, + "Messaging task finished unexpectedly. This indicates a critical system error." + ); - error!(target: "sequencing", reason = ?res, "Block production task finished unexpectedly."); + error!( + target: "sequencing", + reason = ?res, + "Block production task finished unexpectedly. This indicates a critical system error." + );
78-84: Consider implementing a task restart mechanismSince these tasks are critical for the system's operation and are expected to run indefinitely, consider implementing a restart mechanism when they unexpectedly terminate.
This could involve:
- Adding a retry count/backoff mechanism
- Implementing a supervisor pattern
- Adding metrics/alerting for task failures
Would you like me to provide a detailed implementation proposal for any of these approaches?

Line range hint 1-16: Ohayo, sensei! Clean and well-structured type definitions!
The introduction of SequencingFut type alias and the necessary imports for future-based execution show good organization and follow Rust's idiomatic patterns.
Line range hint 35-63: Ohayo! Excellent error handling and task management!
The implementation shows good practices:
- Graceful handling of optional messaging configuration
- Clean separation of messaging and block production concerns
- Proper error propagation
64-88: Verify pipeline separation is complete
The implementation moves towards separating sequencing from the pipeline by implementing IntoFuture, but let's verify there are no remaining pipeline dependencies.
✅ Verification successful
Pipeline separation is properly implemented
Ohayo sensei! After verification, I can confirm that the sequencing module is properly separated from the pipeline implementation. The module:
- Has no direct pipeline imports or dependencies
- Is cleanly exposed through the stage module
- Implements
IntoFutureindependently without pipeline coupling
The only connection is the structural one through the Stage trait, which is the intended design. This separation aligns perfectly with the PR objectives.
