This record contains CT-Gravity: A Kernel-Driven Derivative Model for Emergent Spacetime Tension (v2.7), a derivative (non-axiomatic) working note that proposes an effective gravity channel compatible with C-Theory’s kernel-first core. Gravity is modeled as emergent spacetime curvature sourced by a coarse-grained tension field that quantifies kernel-induced “choice pressure” (informational overlap among admissible continuations) prior to commitment at the Identity Line. The note provides a conservative GR-like action and field equations, plus a minimal “observable channel” dictionary connecting the tension sector to existing constraints such as bounds on time variation of couplings/Newton’s constant and equivalence-principle tests. It is intended for open review and iterative refinement, with explicit placeholders for screening, stability analysis, and covariant source construction.
