FICTIONAL EXAMPLE — learning walkthrough, not customer evidence.
1. Create a project. Upload the requirement file as Buyer requirement,
   then both quotes as Supplier offers (multiple selection is supported).
2. Normal interpretation uses your configured interpretation provider and one
   credit. Downloading this example does not reserve a credit.
3. Compare the proposed conditions with every clause. Correct them if needed,
   save your draft, finish all corrections and explicitly accept the version.
4. Run the calculation. This fully described example expects EUR 160 from A:
   goods EUR 200, discount EUR 40, fees and commitments EUR 0.
   Without the discount, X from B and Y from A would cost EUR 185, including B's fees.
5. To explore the absence of that discount, explicitly create a SCENARIO
   ASSUMPTION, accept the new version and compare it with the first plan.
6. Moving the deadline to 14 November is another assumption: no delivery in
   the model meets it. No actual requirement is replaced.
7. Export Excel, the JSON evidence packet and the separate acceptance receipt.
   Keep the receipt digest through a trusted channel before checking the packet.
Expected amounts are teaching material; only your calculated and checked result
is the output of your attempt. No realised saving is established.
