Black Holes: Horizons and Interiors | G Model Perspective

In general relativity, a black hole is a region bounded by an event horizon from which future-directed signals cannot reach distant observers. The classical theory leaves difficult questions about collapse, interiors, and singularities.
A horizon is a causal boundary in the spacetime description; it should not automatically be identified with destruction of every microscopic degree of freedom.
The G Model investigates whether outward-connected causal-fabric support ends at a black-hole horizon. In the retained strong-field branch, a horizon can support causal trapping and loss of outward-connected support.
The stronger historical claim that an event horizon necessarily destroys the whole local causal fabric was rejected. The four-null Gram remains non-degenerate at the horizon and the Schwarzschild curvature invariant is finite there; deeper-interior fabric loss remains an open hypothesis.
The two-function spherical completion is a conditional model branch. Its exact exterior agreement with Schwarzschild within the declared completion is not a derivation of black-hole interiors or an independent observation.
