Commit222d5186eb('add minimal # Safety comments to 70 files') inserted a '// SAFETY: ...' line mid-token in backend.rs:1405, splitting 'perms.set_mode(0o755);' into 'perms.set_mo' + comment + 'de(0o755);'. The result is a compilation error that prevents the entire redbear-wifictl crate from building — including the new dbus_nm.rs interface frome65a23fd6b. Restore the single-line call. The Safety rationale is captured by the surrounding cfg(unix) block. Verified: cargo check --features dbus-nm compiles, 35 unit tests + 2 cli_transport pass.
