Observable Signatures of Torsion Shell Objects Paper III

General Relativity successfully describes gravitational phenomena across a wide range of scales, yet remains incomplete in regimes where geometry, matter compaction, and field self-interaction intertwine. In the ECT framework, torsion is promoted from a purely auxiliary geometric quantity to a dynamical field capable of forming compact, shell-structured configurations. We define \emph{torsion-shell objects} (TSOs) as static or quasi-static solutions of the torsion field that generate effective gravitational potentials while exhibiting internal shell structure. Unlike metric-only compact objects, TSOs encode additional geometric degrees of freedom that may leave observable imprints without violating established weak-field constraints. Paper II established the covariant action and strong-field solution sector, while the complete linearised degree-of-freedom and stability certification was given in paper I. The purpose of the present work is to move decisively into phenomenology by constructing explicit solutions and extracting observational signatures.
