Please use GitHub private vulnerability reporting for this repository. Do not open a public issue for a suspected credential leak, path-traversal bug, unsafe uninstall, or command-injection issue.

Include the affected version, macOS version and architecture, reproduction, and the smallest safe diagnostic output. Remove tokens, endpoints, usernames, and workspace names.

Security fixes target the current minor release. Release artifacts include SHA-256 checksums and GitHub build provenance.

The direct-install runtime supports macOS's system Ruby 2.6 so it can start without bootstrapping another language runtime. Ruby 2.6 is upstream end-of-life; AI Environment Optimizer therefore uses only the operating-system Ruby standard library, does not open a listening service, does not parse untrusted network responses in normal doctor runs, and also tests under Homebrew's maintained Ruby. This tradeoff will be revisited if macOS removes the system runtime.
