@Cirdan nope, thanks! but I'll keep an eye out
@Cyberpower678 the fourth change down was |deadurl=yes so maybe this is just terminology? The edit summary Rescuing 13 sources and tagging 0 as dead. #IABot (v1.6.5) implies that 13 archive URLs were added and none of the original sources were dead, when in reality, "Rescued 13 sources, of which one was dead." Does this mean that the second number, as used, is meant to denote sources that could not be rescued? Might be better to clarify that, e.g., "Added 13 archive URLs; unable to rescue 2 dead links."
I think of the bot's main functions as rescuing dead links, adding archive URLs for not-yet-dead links, and marking dead links that cannot be rescued. Would be nice to have those counts reflected in the summary when >0
