• TODO: How to find a payload ID to test? Inspect piece-indexer Redis state?
• See also Support retrievals from multiaddrs with http-path segment roadmap#239
• bafkreih74ljilat42tptlywlnuejfkyigun6ahor5gmkxemqkvvdftasg4 could be a good one to use. However, at the time of writing this comment, the SP was advertising an incorrect retrieval address. (cid.contact query, correct retrieval address).

This requires other tasks listed in CheckerNetwork/roadmap#231 to be implemented first.
