G-001 pluggable console backends for non-detectable terminals (ssh channel, tk widget) via ::opunk::Console subclasses. G-002 non-nested subshell with console targeting and inter-subshell comms, including thread::send -async routing to the code sub-interp and the canonical launch API design (subshell as sole entry point, interp alias as context signal). G-003 configurable resource limits (command-count, time via interp limit) and sandboxing spectrum (interp hide/expose/alias, safe::interpCreate) on subshell interps, downstream of G-002's asymmetry fix.
