Tests load research drivers via importlib under unique module names instead of a bare 'import run' (shared-process collision between the Dütsch and VIV drivers). lifecycle.md qualifies immutable geometry and the host-only get_flags for translating circles; supported_settings.md points to the dense-only moving-circle feature; leontini_viv_predeclare.md is renamed viv_re150_predeclare.md (Re 150 Kolahdouz/Qin case) with references updated.
