libiconv is the only /nix/store dep the darwin stdenv bakes in (everything else is system frameworks + libSystem/libobjc). The smoke-test now rewrites that load path to /usr/lib/libiconv.2.dylib (ABI-compatible, present on every Mac), re-signs ad-hoc (install_name_tool breaks the sig; arm64 requires a valid one), then verifies no /nix/store paths remain, the signature is valid, and the native binary launches. Flake comment updated to reflect the propagated-libiconv reality.
