Schwarzschild Geometry: Spherical Vacuum Solution | G Model Perspective

The Schwarzschild solution is the spherically symmetric, static, vacuum solution of Einstein's field equations outside an uncharged, nonrotating source. Coordinate choices describe the same geometry in different forms.
Its exterior predictions and horizon structure are part of the established relativistic comparison framework.
The retained two-function spherical completion uses ψ = 2 tanh(M/2), T = e^M, and X = (1 − ψ/2)². With ψ = −μ/r, it gives the isotropic Schwarzschild exterior within the declared conditional completion.
The exterior is exactly Ricci-flat and coordinate-equivalent to Schwarzschild inside that mathematical branch. The earlier one-function reciprocal exponential metric failed as a nontrivial exact static-vacuum solution and is retained only as historical or weak-field material.
This result does not derive the strong-field completion from complete finite-cell dynamics or establish black-hole interiors.
