 The test failure reported on CRAN (MKL) was caused by a numerical rounding issue 
 leading to a non-symmetric correlation matrix. This has been fixed by ensuring 
 correlation matrices are properly symmetrized.
 
+In addition, fixed a unit test that incorrectly assumed exact agreement 
+between empirical and target correlation matrices. The test has been updated 
+to allow for expected Monte Carlo variability and BLAS/LAPACK–dependent 
+numerical differences, which should resolve the MKL-specific test failure.

 Checks using devtools::check(remote = TRUE, manual = TRUE) and 
 devtools::check_win_devel() pass.
