"hypothesis": "Moving the public76 diagonal loop from doubled radius7 to75 and rerouting the outer path9-75-1 through7 may admit a valid152 with corners when all remaining orbit orientations are free.",
"method": "Remove source outer edges(9,75),(1,75) and loop7. Add corner loop75 and edges(1,7),(7,9). Preserve all other unsigned source edges but free every edge orientation. Build a complete exact orientation SAT formula from every collinear triple among the300 potential cells; fixed corners have no sign variable. Save every clause origin; verify UNSAT with independent DRAT-trim, or independently check152 and149 crop. Also evaluate the4 choices of new signs while retaining other source signs for a baseline.",
