Sources and auditability

Trace every number

Click any figure to see the formula behind it and the document it came from. AI reads the documents; the engine does the math, the same way every time.

Formula and provenance on every cell

Every output shows the formula that produced it and the inputs it depends on. Each input carries the document it was read from and a confidence signal.

  • Formula and dependency behind every output
  • Document provenance and confidence on every input
  • Self-checks that reconcile the model end to end

Deterministic math

Anyone with the same assumptions reproduces the same number, to the cent. The IRR solver carries guardrails against the spurious roots a spreadsheet function can return.

  • Same inputs, same result
  • Decimal-exact, no float drift
  • Guarded IRR solver, no spurious roots
