9-13: Refactor: Import and use of new libraries.The new libraries
InternalLeanIMT,LeanIMTData, andPoseidonT3are imported and used to manage the cipher nodes with an incremental Merkle tree. This change aligns with the PR objectives to enhance node management efficiency.
16-16: Best Practice: Use of library functions on data types.The
usingstatement forInternalLeanIMTonLeanIMTDatais a good practice in Solidity, enabling more readable and maintainable code by attaching library functions directly to the data type.
117-125: Enhancement: UpdatedaddCiphernodefunction.The function now converts the node address to a
uint256and uses the_insertmethod fromInternalLeanIMTto manage the cipher nodes. This is a significant improvement over the previous boolean tracking mechanism, enhancing both performance and scalability.
128-142: Refactor: UpdatedremoveCiphernodefunction.This function now accepts an additional parameter
siblingNodeswhich is necessary for the removal process in the incremental Merkle tree. The function also correctly updates thenumCiphernodescounter and emits detailed events about the state changes, which improves transparency and traceability.
146-146: Refactor: Renamed function toisEnabled.The function
isCiphernodeEligiblehas been renamed toisEnabledto better reflect its functionality, which checks if a node is enabled in theciphernodesstructure. This change improves clarity and consistency in the codebase.
162-164: Enhancement: Implementation ofisEnabledfunction.This new function provides a public interface to check if a ciphernode is present in the Merkle tree, using the
_hasmethod fromInternalLeanIMT. This is a straightforward and efficient way to check node status, aligning with the PR's goal to enhance node management.

Enhanced event parameters for CiphernodeAdded.
The addition of index, numNodes, and size parameters to the CiphernodeAdded event is a positive change that aligns with the PR objectives of enhancing node management. These parameters provide valuable context about the registry's state when a node is added, which can be crucial for listeners tracking changes.
Suggestion: Improve parameter documentation.
While the parameters are well-named, adding a brief description in the comments for each parameter could improve clarity and developer experience.

Enhanced event parameters for CiphernodeRemoved.
The addition of index, numNodes, and size parameters to the CiphernodeRemoved event mirrors the changes made to the CiphernodeAdded event, maintaining consistency and enhancing the utility of these events. This change allows listeners to better understand the impact of a node's removal on the registry.
Suggestion: Improve parameter documentation.
As with the CiphernodeAdded event, enhancing the documentation for these new parameters would further improve clarity and usability.
