The regular neighborhood with actual inverse mean-Gram mass matrices

theorem OAI.RegularPointCoordinates.exists_regular_mean_pinching_neighborhood line 20
Source documentation
The precise published inputs construct one common harmonic/heat family with an arbitrarily small summable source and the full directional mass estimate for every nearby pair. No pinching hypothesis is assumed.
