Reference budget calculation
UNIT TEST: tests/unit/financial.test.ts
In SiteLedger, financial numbers are never estimated loosely. The financial engine enforces strict fixed-precision arithmetic across baseline budgets, commitments, invoices, and payments:
Baseline Budget₹10,00,000
Approved Invoices₹1,50,000
Remaining PO₹2,50,000
Additional ETC₹5,00,000
Headroom Remaining₹1,00,000
Forecast at Completion = ₹1,50,000 + ₹2,50,000 + ₹5,00,000 = ₹9,00,000 ≤ ₹10,00,000 (Safe)Interactive Test Drive
