# Scientific Scope

SSZ is a scientifically serious, mathematically concrete and falsifiable strong-field research programme. It is not yet a complete or empirically confirmed fundamental theory of gravity.

## Established within the declared model

- a concrete scalar field and diagonal metric ansatz;
- explicit strong, blend and weak branches;
- finite declared horizon values `Ξ(r_s)≈0.801711847` and `D(r_s)≈0.555027709`;
- computable observables and reproducible implementations;
- explicit weak-field/PPN compatibility paths;
- concrete falsification opportunities.

## Not established

- a globally regular centre;
- complete singularity freedom;
- a fundamental action and complete field equations;
- geodesic and causal completeness;
- a non-perturbative rotating solution;
- a complete gravitational-wave waveform theory;
- unique empirical preference over GR.

For the canonical diagonal continuation, `A→1/4`, `R~3/(2r²)` and `K~9/(4r⁴)` as `r→0`. This is the controlling P0 correction.
