Greptile Overview

Greptile Summary

Updated cosmos-xenna dependency from version 0.1.2 to 0.1.8 to access latest features and improvements. The version bump introduces two new transitive dependencies:

• obstore 0.8.2: Object storage library providing a unified interface for cloud storage backends
• portpicker 1.6.0: Utility for selecting available network ports

The update is straightforward with no breaking API changes. cosmos-xenna is used by the XennaExecutor backend (in nemo_curator/backends/xenna/) for distributed pipeline execution. The version increase from 0.1.2 to 0.1.8 includes 6 minor releases, suggesting accumulated bug fixes and feature enhancements.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• This is a straightforward dependency version bump with no code changes. The update follows semantic versioning (0.1.2 → 0.1.8) indicating backward-compatible improvements. The new transitive dependencies (obstore and portpicker) are well-established packages with appropriate version constraints. The lock file changes are automatically generated and properly updated. No breaking changes expected.
• No files require special attention
