One quite perplexing common theme is "thing gets flagged -> thing gets resolved by a human as a false positive or whatever -> two weeks later, thing gets flagged again with no change, presumably by an automated system".

If the flagging is done by a human, is there really no "case file" that records the previous flags and why they were false positives? If it is done by an automated system, why is it allowed to flag things that a human has already cleared with no change?
