+ * @brief Validate that (eigenvalues[i], eigenvectors[:, i]) are genuine
+ * eigenpairs of `A`, without relying on hardcoded golden eigenvalues.
+ *
+ * Checks the defining characteristics of a converged real-symmetric
+ * eigensolve, split into eigenVALUE-accuracy checks (held tight for every
+ * mode) and eigenVECTOR-accuracy checks (relaxed for smallest-magnitude
+ * problems, see below):
+ *   - lambda_i matches the Rayleigh quotient (v_i^T A v_i)/(v_i^T v_i). This
+ *     is the primary correctness check: it confirms the returned eigenvalue
+ *     is the true eigenvalue for the returned eigenvector direction, and it
+ *     is stationary at eigenvectors, so its error is second-order in the
+ *     eigenvector error while the residual's is first-order.
+ *   - eigenvalues are returned in ascending algebraic order (verified
+ *     against every previously-hardcoded golden array in this file, which
+ *     were all ascending regardless of `which`).
+ *   - ||A*v_i - lambda_i*v_i|| is small (see lanczos_solver_config::tolerance,
+ *     documented as governing exactly this residual).
+ *   - each eigenvector is unit-normalized.
+ *   - distinct eigenvectors are mutually orthogonal (catches "ghost"
+ *     duplicate eigenpairs from loss of orthogonality).
+ *
+ * The three eigenVECTOR checks (residual, normalization, orthogonality) are
+ * loosened for LANCZOS_WHICH::SM. Smallest-magnitude eigenvectors are
+ * ill-conditioned -- a tiny eigenvalue buried deep in the spectrum is highly
+ * sensitive to rounding -- so the eigenvector residual grows by orders of
+ * magnitude and varies across CUDA versions and GPU architectures, even
+ * though the eigenVALUE stays accurate (see issues #2705 and #2758). For SM
+ * we therefore assert eigenvalue correctness tightly via the Rayleigh
+ * quotient and only sanity-bound the eigenvector; for all other modes the
+ * eigenvector is well conditioned and held to the tight noise floor.
+ *
