  We construct a global homeomorphism from any 3D Ricci limit space to a smooth
manifold, that is locally bi-Holder. This extends the recent work of Miles
Simon and the second author, and we build upon their techniques.
  A key step in our proof is the construction of local "pyramid Ricci flows",
existing on uniform regions of spacetime, that are inspired by Hochard's
partial Ricci flows.
