+      # ---- Rust toolchain ---------------------------------------------------
+      # The dnssec_proof plugin builds its native lib through cargokit
+      # (windows/CMakeLists.txt -> apply_cargokit), so `flutter build windows`
+      # genuinely needs cargo/rustc — the prebuilt monero_c bundle doesn't
+      # cover it.
+      #
+      # setup-windows-runner.ps1 installs Rust to C:\Rust and puts
+      # C:\Rust\cargo\bin on the *Machine* PATH, but the act_runner service
+      # only picks up Machine PATH changes when it restarts, and a rebuilt or
+      # re-imaged box loses it entirely. Either way the job died at exit 127
+      # ("rustc: command not found"). Locate it ourselves, and install it if
+      # it really isn't there, so CI doesn't depend on the box's env being
+      # right. No-op when rustc is already on PATH.
