The author of the message expresses gratitude for assistance and provides a summary of the solution arrived at for an M of N "single sig" extension of MuSig, which involves using MuSig's blinding solution to solve the Wagner attack and interpolation to enhance MuSig to be M of N instead of M of M. The process involves each party publishing public key G*xi, computing Xi and r, and deriving e and si for each participant. Any party can derive s from m of n shares by interpolating rather than adding. The references used include MuSig and HomPrf.
