# Scenario Analysis Range Consistency Check

## Inputs
The scenario set, the assumption sheets per case and the base case.

## Workflow
1. List the assumptions each scenario is meant to vary.
2. Diff every scenario against the base case.
3. Flag scenarios that vary unstated assumptions.
4. Return the check without editing the model.

## Output contract
Scenario | stated change | unstated changes | flag | reviewer

## Fictional acceptance test
Fictional downside case should vary only revenue -15%; the diff also shows headcount frozen and marketing cut 30%, two unstated changes. Flag 2 unstated changes.

## Review gates
Re-check the diff covers every input tab. An unstated change makes the scenario a different story, not a downside case.
