Forecast

Verify forecast receipt

Default response is the exact canonical UTF-8 manifest committed by SHA3-256, including a private random nonce, forecast values, input cutoff and generation time. Keep these bytes unchanged when verifying. X-VBase-Content-CID identifies the committed bytes. verify=true recomputes the saved content CID and looks up the stamp in Quantura’s vBase collection/account, returning content_matches, stamp_found and verified_at in the data envelope. format=envelope returns manifest_utf8 and provenance for authenticated browser downloads. Receipt verification proves content/time, not accuracy or prospective publication before the stamp time. Reads do not create stamps or write Firestore documents.
