From 2a12b6cb0ac588973d8871d7b366f85006dd5944 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Jul 2026 12:27:52 -0400 Subject: [PATCH] test(bf-3x4rp): add missing Stdio import to encryption test files - Add std::process::Stdio to imports in both test files - Update code to use imported Stdio instead of fully qualified paths - Verify compilation succeeds with cargo check Closes bf-3x4rp.
