Your goal: reproduce the calculation later
- Calculate a workload and choose Download calculation evidence.
- Keep the JSON receipt: it contains numeric profiles, the complete public endpoint snapshot, capture time and exact lines.
- In Calculator, expand Replay a saved calculation and select the receipt.
- The local worker checks source content hash and recomputes results. Changed results, invalid identity or unknown versions are rejected.
Refreshing rates does not rewrite old receipts. Their snapshot is not a promise of today's prices. A SHA-256 hash identifies source bytes, not a vendor signature or proof of a paid invoice. Historical verification needs applicable price-period evidence and every billed component.
Read the formulas or the endpoint rate schema.

These explanations describe Examenos's data and display policy. Calculator examples are explicitly hypothetical. Inspect dated endpoint evidence and the formulas; projections do not authenticate a bill.
