Erdős Problem 364: kernel-checked finite range versus an unbounded powerful-number conjecture

Expected conclusion: NO_GLOBAL_CONCLUSION_EXPECTED.
Oracle summary: The exact bounded statement through 10^14 is kernel-checked by the referenced artifact. Its scope is finite. The global no-three-consecutive-powerful-numbers conjecture remains open, and current Jacobian does not install the artifact's environment or its chunk-certificate replay.
