Observable Hierarchy and Transport Reconstruction of a Frustrated SU(2) Vacuum on the Diamond Lattice

We study the 9-dimensional gauge-field fluctuation space above the frustrated SU(2) vacuum (Tr(W) = -10/27) on the diamond lattice within the Granular Entropic Physics programme. A hierarchy of gauge-invariant observables is established, ordered by collective depth. Single traces Tr(W_I) have identically vanishing gradients at the vacuum, a structural SU(2) property. Hexagonal plaquette products (17 invariants including pairwise, triple, quadruple, and commutator structures) saturate at rank 5. Transported observables Tr(W_A T W_B T-dagger) achieve rank 6 per transport topology, consistently across all 30 tested topologies. Full rank-9 reconstruction requires combining at least 3 distinct transport topologies (minimal basis: 9 observables). The reconstruction is highly anisotropic, with effective observable dimension D_eff between 3 and 6, far below the algebraic rank 9. No single transport topology stabilises the Wilson saddle point. The paper includes a self-correction of an earlier dark-sector interpretation, which was shown to be an artifact of an insufficiently rich observable basis rather than a structural property of the vacuum. The central result is that the frustrated vacuum is a transport-sensitive collective phase whose full characterisation requires a multi-topology observable atlas.
