Debt roll-forward · PASS

Opening + draws + capitalised interest − principal = closing debt.

Project CF identity · PASS

EBITDA − tax − capex + residual value reconciles to project cash flow.

Terminal debt · PASS

Debt fully amortises within the concession.

Input integrity · PASS

Core input relationships are internally consistent.
