The console's one-click local-instance launcher predates the unified build and never set the platform env -- instances booted the DEV profile (no PadRIO), so the legacy arrow-drive bridge owned the keyboard instead of the bindings.txt keymap (arrows drove fwd/back/turn, Alt-reverse dead). The join bats already set it; now the operator's QProcess env does too. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
