  "Description": "Fits linear and generalized linear mixed-effects models\nfrom 'lme4'-style formulas, with optimization by the bundled\n'mixeff-rs' Rust crate. A fitted model stores the compiled\nmodel specification, the optimizer certificate, and\nper-coefficient inference metadata (method, status,\nreliability) as data, so a result can be inspected, saved, and\nreloaded without a live handle to the compiled engine. When an\ninference method is unavailable for a fit, the affected value\nis either withheld with a stable reason code or reported under\nthe name of the method actually used, never silently swapped.\nVignettes cover migration from 'lme4' and the meaning of\nrandom-effects formula syntax.",
