-Linux release archives include the `ai` launcher plus hidden runtime payload
-files used to make the prebuilt binary work on hosts that do not provide every
-Node/GCC runtime library by default. Prefer `install.sh` or copy the entire
-extracted archive contents together; copying only the hidden `.ai-real` binary
-can fail with missing libraries such as `libatomic.so.1`.
-
-On NixOS, the Linux launcher falls back to Nixpkgs' dynamic linker when the
-usual `/lib*/ld-linux*` path is absent. If you manage `ai` declaratively, prefer
-a Nix/Home Manager package so upgrades are pinned and reproducible.
