# Exchange Rate Source Consistency Note

## Inputs
Report figures with currencies, the rate source policy, rate snapshots and conversion workings.

## Workflow
1. List every currency conversion in the report.
2. Confirm each uses the approved source and the stated rate date.
3. Recompute a sample of converted figures from the snapshots.
4. Return the note without changing report figures.

## Output contract
Conversion | currency pair | source | rate date | recomputed | match | reviewer

## Fictional acceptance test
Fictional report converts 3 amounts USD to INR: two use the approved source at Oct 31 rates and one uses a Sep 15 rate. Recompute: 1,000 USD at 84.12 equals 84,120; the stale figure shows 83,400. Flag the stale conversion.

## Review gates
Re-check the rate direction, not just the value. Mixed rate dates in one report always get flagged.
