Omar SobhandClaude Fable 5	87cf392556	rtx-fea: re-enable the remaining CPU test modules; fix three real defects they caught ... All 33 remaining #[cfg(disabled)] test modules outside the GPU cluster are now enabled: assembly (dof_mapping, constraints, global assembly), boundary (mod + dirichlet/neumann/robin/thermal/contact), analysis (mod + static), materials (mod, linear_elastic, hyperelastic, plasticity), elements (mod, element_matrices, isoparametric, jacobian, quadrature), mesh (element_types, connectivity, topology, topology_repair), solvers (mod, direct, iterative, nonlinear) and lib.rs. Lib tests 117 -> 335, stable across repeated runs. Only gpu_solver_tests and the GpuMeshData fixture stay disabled — they need CUDA hardware and belong to the GPU tranche. Three real defects found by the newly-compiling tests, each fixed: - Direct solvers reused factorizations keyed on matrix SIZE alone. In a Newton loop the Jacobian changes every iteration but never its dimension, so LuDirect/CholeskyDirect/LdltDirect silently solved with the first iteration's factorization forever — Newton on x^2-4 crawled to x=1.955 in 1000 iterations instead of converging in 5. Invisible in single-solve linear analysis, which is why every green test passed over it. solve() now factorizes the matrix it is given. - AdaptiveQuadrature's refinement re-integrated the WHOLE domain once per subdomain, so each level multiplied the estimate by the subdomain count: integrating e^x over [-1,1] at tolerance 1e-10 returned ~75 instead of 2.35. The recursion now descends into each sub-box with its share of the error budget. - compute_skewness read Jacobian columns as coordinate-line tangents, but the trait's jacobian() stores tangents in ROWS: on a sheared parallelogram whose tangents meet at 14 degrees it reported skewness 0.43 instead of 0.84 — measuring per-component gradients, not mesh skew. Fixtures corrected rather than the code where the fixture was wrong: sigma_yy ~ 0 asserted uniaxial-stress physics on a uniaxial-strain state (exact Lame values now asserted); an "unstable" orthotropic parameter set that satisfies the determinant stability condition (delta = 0.187 > 0); a unit-cube hex Jacobian of 1.0 that assumed a unit reference element (it is 0.125 from [-1,1]^3); a "distorted" quad whose centre Jacobian is exactly orthogonal, asserted as skewed (flattening and shearing now tested separately); a quality score below the implementation's own calibration; Rayleigh damping fed the scalar-field mass (now expanded via the Kronecker identity, with C = alpha*M + beta*K asserted entry-wise); an element factory required to construct Point/Line types that have no implementation; and DOF counts that encoded the repaired 3-DOFs-per-node-on-2-D defect. MaterialDatabase::add_material call sites updated to the (id, material, name) signature; ConnectivityInfo::build takes elements only; TopologyRepair::triangle_quality (normalized 4*sqrt(3)*A/sum(a^2)) added for the repair tests; create_subdomain_rule_* widened to pub(super) for the quadrature tests.
