[#R1762] Dated status and exact unresolved remainder

claim. Unresolved in this packet after the dated source check. Strongest checked result: Chambers proves the result for curves sufficiently close to a C2 Jordan curve. Greene and Lobb obtain squares for a further area-versus-diameter class. The general continuous case remains open. Exact unresolved remainder: Prove every Jordan curve inscribes a nondegenerate square, or certify a Jordan curve with none.
