@loanscope/compare

Comparison grid builder, executor, and goal-seek for evaluating a LoanScope mortgage scenario across multiple dimensions (term, rate, LTV, loan amount, occupancy, products, lenders, borrower sets, FICO, down payment, property type, loan purpose). Produces a GridResult with per-cell evaluations and a GridSummary aggregating eligibility counts.

Goal-seek searches for the maximum (or other criterion) value along a single knob given target check satisfaction.
