Summary of Changes

Hello @andrewrobinsonhodges-snyk, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the robustness and clarity of the codebase, particularly concerning how organization configurations are managed within delta scans and CLI extension executions. It ensures that base branch scans correctly utilize folder-specific organization settings, preventing potential inconsistencies. Additionally, the changes include general code hygiene improvements such as optimizing logging practices and refining function signatures for better maintainability, alongside a minor but important update to a related test case.

Highlights

• Delta Scan Organization Configuration: The populateOrgForScannedFolderConfig function in base_scan.go was refactored to explicitly accept the configuration object and now includes improved comments explaining its role in ensuring consistent organization settings for base branch scans during delta scan operations. Error handling and debug logging were also added for retrieving folder configurations.
• Logging Refinement: Logging within cli_extension_executor.go was improved by centralizing the logger instantiation at the beginning of the Execute and doExecute methods, leading to cleaner and more consistent log statements.
• Test Coverage Enhancement: An additional assertion was added to cli_extension_executor_test.go to explicitly verify that the global organization flag is not included in command arguments when a folder-specific organization is successfully applied.
• Function Signature Cleanup: The Scan function in iac.go was updated to mark an unused folderConfig parameter as anonymous, improving code clarity.

Code Review

This pull request tidies up comments, logging, and function signatures, which improves code clarity and maintainability. The changes are mostly good, especially the refactoring of logging to use a structured approach and the improved error handling. However, I found one issue in the logging refactoring where an incorrect error variable is being used, which could lead to misleading logs.
