- Updated README.md to enhance clarity on the one-time export process, including detailed prerequisites, data structure, and validation steps. - Revised install_mars956.sql to streamline installation commands and improve logging mechanisms. - Modified rollback_mars956.sql to include user confirmation before proceeding with deletions and to clarify rollback steps. - Removed unnecessary tracking and validation scripts (track_package_versions.sql, validate_export.sql, verify_packages_version.sql) to simplify the package structure. - Enhanced error handling and validation checks throughout the installation and rollback processes.
