# Cash Cycle Negative Duration Evidence

Explain a negative cash-cycle result without treating it as a calculation error or financial health verdict.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
DIO/DSO/DPO, formula policy, periods, units and payment-timing evidence.

## Workflow
1. Verify DIO+DSO-DPO under one basis.
2. Retain negative results when the supplied numbers support them.
3. Separate arithmetic from an explanation of customer/supplier cash timing.
4. Return timing questions; no credit or solvency conclusion.

## Output contract
DIO | DSO | DPO | CCC | arithmetic_valid | timing_evidence | inference_hold

## Fictional acceptance test
Fictional 10+5-25=-10 days. Negative is arithmetically valid, not automatically a sign error. It does not by itself prove healthy cash flow or supplier payment compliance.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
