1629-1657: Optimize logging to handle large tip sets gracefully.Logging the entire set of tips at the info level could generate excessive log output if the DAG grows large. Consider only logging the size of the tips or switching to a debug level if the number of tips can become large.

1555-1571: Ensure KeyNotFound scenario is appropriately handled.When encountering a
KeyNotFounderror for the parent pruning point, this logic creates a new DAG state using the parent’s ID as the lone tip. While this is a valid recovery strategy, please confirm that this behavior aligns with the intended chain continuity and that no alternative configuration is inadvertently overwritten.Would you like a script to trace potential orphan states and confirm that the parent block is part of the main lineage before creating a new DAG state?
1624-1627: Good invocation ofrenew_tips.Calling
self.renew_tipsensures tips remain consistent with updated pruning points prior to returning the executed block. The error propagation using?properly prevents partial state updates.
1, Save the new tips with the new block header not the selected header. If they are the same as another, the main header tips will be affected, else, the sub branch of the main will be affected.
2, Create the tips using parent id if the new block header's parent's pruning point was not saved.
