Gravitational Sector Under LST

We formalize the gravitational content of Light-Space Theory / Gauge Theory / ACE (LST/GT/ACE) as a set of explicit postulates that extend GR with a dimensionless field d(x) = 3 - D_eff(x) and Light-Space structure. Near the vacuum d_vac, the dynamics are captured by a canonical two-derivative EFT (P1). Two Light-Space rules control radiation and black-hole hair: an environmental mass unlock in the radiative vacuum (P2) and a horizon boundary law that supports a surface scalar charge (P3). A collapse condition (P4) specifies how Light-Space modifies the hypotheses of classical singularity theorems. This approach removes ambiguities between different physical regimes and transforms the theoretical narrative into a set of falsifiable equations that are both explanatory and robust to critical review.
