Integrated current route, one-hundred-twenty-second refinement #
Route122 combines three independent lowerings:
- candidate actual obstruction/Frattini replacements;
- target Route46 canonical lower-quotient / ambient-action bridge;
- compact Route120 kernel closer, removing the theorem-level upper-candidate least-kernel leaf.
This is a work route, not the promoted public route.
