    "message": "Standardized parameters for psychonetrics models; fix regsem importer and examples\n\npsychonetrics leaves the 'std' column of its parameter table empty, so\nsemPaths(mod, 'std') had nothing to plot. Compute the standardized solution\nfrom the model-implied matrices instead:\n\n  Var(eta) = (I - Beta)^-1 Sigma_zeta (I - Beta)^-T\n  Sigma    = Lambda Var(eta) Lambda' + Sigma_epsilon\n\nFor a GGM block psychonetrics forms Sigma_* = Delta (I - Omega)^-1 Delta, so\nthe same expressions cover the cov/ggm/chol/prec parameterizations of both the\nlvm and varcov frameworks. Omega is itself a matrix of partial correlations\nand is reported unchanged.\n\nAlso fixes an empty GGM block (every omega fixed at zero, as for a default\nresidual = 'ggm') losing its delta parameters to the '~/~' operator warning,\nbecause the block's parameterization was read after structurally-zero rows had\nbeen dropped.\n\nThe regsem importer's ':='/'=='/'<'/'>' filter tested object$op; a regsem\nobject has no $op, so partial matching resolved it to optim_fit and the filter\nwas a constant. ?regsemplot called the unexported S3 method by name.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>\n",
