Issues

• shift_discrete_system: substitution rebuilds a + with mismatched shapes (Unknown(2) vs scalar) on MTK 11.37

• state_priority ineffective across alias equations of unequal differentiation depth: singleton-SCC demotion that #103's block merge cannot reach (forced by tier mismatch)

• state_priority ineffective when the prioritized variable's derivative is matched to a differentiated alias equation (singleton SCC forces demotion; singular Cartesian states in a planar arm)

• Inline linear SCC emits an inconsistent runtime system (rank 14/15, ‖Ax−b‖/‖b‖ ≈ 1) at a consistent state — integration goes Unstable

• Inline linear SCCs: 296×296 dense runtime solve for an ~18-unknown core; non-rank-tolerant; symbolic shrinkage intractable — solve sparse+rank-tolerant instead
