Gated two-step chain: quantify the OBBBA 2025 federal Direct Unsubsidized / Grad PLUS cap funding gap for a graduate or professional program. A fully funded result routes to end — no residual gap means there is nothing left to finance, so a graduate-school ROI comparison would be redundant. Only a positive gap continues to the ROI comparator.
OBBBA 2025 P.L. 119-21, effective July 1, 2026: $20,500/yr ($100k lifetime) grad · $50,000/yr ($200k lifetime) professional · $257,500 overall aggregate
/summary/funding_gap ≤ 0 → routes to end. This chain stops here — Step 2 does not run when the federal cap plus aid already fully funds the program.
