Trust is the primary value, because it covers everything you listed.

Most people who read research papers only skim through the paper to get the big picture. They trust that the authors and the publication system did a good-faith effort to advance science. If they can't trust that, they almost certainly won't read the paper, because they don't have the time and the interest to go through the details. Only a few people read the technical parts with the intent to understand them. Even fewer go through supplementary materials and external reproducibility instructions with a similar attention to detail.
