  "requirements": "Compare complete monthly cash scenarios with different receipts, payments, growth and financing timing. Start funding arrives before monthly operations; end funding arrives afterward. A negative balance before end funding remains visible even when closing cash recovers. The reserve test uses strictly below, so cash equal to the reserve does not breach it. The report continues through negative balances. A monthly model cannot establish intra-month solvency. No credit, taxes, interest or unentered funding is assumed. Runs on your device without uploads in a cancellable worker with a 10-second timeout. Limit: 250000 combined input characters, 20 scenarios, 600 monthly periods or 1000 invoices. Complete JSON and typed JSON Pointer CSV files each have an 8000000-character limit; CSV is limited to 250000 values. Preview shows 200 rows. Inputs are preserved in downloads. All results use floating-point arithmetic without payment rounding.",
