❯ nix repl -L
Lix 2.94.0-dev-pre20250913-8981fb5
Type :? for help.
nix-repl> p = import <nixpkgs> { system = "aarch64-darwin"; }                                              
Added p.

nix-repl> src = p.runCommand "xattr-source" {} "touch $out; /usr/bin/xattr -w systems.lix.test value $out"
Added src.

nix-repl> :b p.runCommand "xattr-read" {} "/usr/bin/xattr -l ${src} >&2"
xattr-read> systems.lix.test: value

this does not happen on linux. can we forbid this inside the sandbox until we support xattrs everywhere?
