# Statistical Claim Checker

Get recalculated figures, source locations and severity-ranked corrections.

## Requirements

Provide the claim, original data or source, units and relevant dates.

## Workflow

1. Extract the quantity, denominator, comparison window, unit and claimed uncertainty.
2. Locate the source rows and confirm the same population and definitions are used.
3. Recalculate with explicit arithmetic, preserving missing data and units.
4. Distinguish percentage-point changes, percentage changes and causal claims.
5. Report the supported statement and any unresolved assumptions rather than giving a single opaque credibility score.

## Worked example

Read `examples/input.txt` and `examples/expected.txt` before adapting the workflow.

## Acceptance checks

Show both denominators and both change definitions; do not infer significance or causation from these totals.

## Limits

Missing source data stays unresolved. This recipe does not replace domain-specific statistical review.

Worked example included. Model-specific performance and vendor compatibility have not been benchmarked.
