Worked on hardening command option handling in the lima-vm/lima CLI tools, focusing on improving reliability and predictability for copy operations. Addressed a bug in the Command() function by ensuring immutability of command options, using a local variable to prevent unintended mutations across calls. This approach preserved the integrity of stored options and resulted in more consistent tool behavior. Added regression tests in Go to verify that the Command() method remains non-mutating, strengthening test coverage and reducing the risk of future regressions. Updated documentation to clarify command semantics, contributing to more stable automation and clearer expectations for software development workflows.
