Invoice
The original payment request, timestamped before payment was made.
Receipt
Proof of payment, timestamped and anchored to the Bitcoin blockchain.
The .json files contain the invoice and receipt data.
The .json.ots files are OpenTimestamps proofs — verify them independently with
ots verify or istampit info.
Upgraded proofs (with Bitcoin attestation) overwrite the pending ones automatically.
