List of h-entrys with an h-card at the same level

(originally posted 2018-02-18 on the wiki)

Both https://adactio.com and https://miklb.com use a pattern that is not supported by the current authorship algorithm. On those pages, there is a list of h-entrys as well as an h-card at the same level. There is no author property on the h-entrys, so nothing currently links those entries to the h-card. Is this a pattern that should be recognized by the authorship algorithm? Or should we encourage them to change that markup?

Start by reviewing the authorship algorithm's handling of h-entry and h-card elements, using the adactio.com and miklb.com examples as the reported cases. Determine whether sibling h-entrys should inherit authorship from the h-card, or whether the markup should instead be changed; document the decided behavior and its expected outcome.
