@jgdina/core

Environment-neutral contracts, input validation, resource guards, structured errors, and backend orchestration for jGDINA v1. This package does not contain the numerical estimator; use jgdina for the direct engine or inject a FitBackend with createJGDINA().

import { estimateFitMemory, validateFitInput } from "@jgdina/core";

const validated = validateFitInput({ responses, qMatrix, model: "GDINA" });
const estimate = estimateFitMemory({ respondents: 1_000, items: 20, attributes: 5 });

The memory estimate includes worker transport and a conservative runtime reserve by default. It is an admission aid, not a measured peak-RSS guarantee. Application code should normally use a high-level runtime package rather than passing ValidatedFitInput across its own trust boundary.
