Appendix: Navier–Stokes connections to vacuum gravity

Two appendix lessons to the forced Navier–Stokes blowup argument. The first encodes smooth compact incompressible velocity snapshots in exact gravitational constraint data and recovers the velocity. The second derives a separate linear gravitational shear model with a Navier–Stokes limit. These connections do not establish a gravitational singularity or a gravitational continuation through fluid blowup.

Read both appendix lessons and their ten solved exercises.
