Scenario 3b — the fix: update, and let time do the explaining

The same story with the everyday verb. @70's keyed add finds conversation already exists, so the rule lands AT ITS MOMENT — a system message after @28: nothing before it can contradict it, no marker needed. The @74 reply exhibits it. @80's re-add supersedes at ITS moment, after @74 — again coherent by position, and the entire request above it stays cached. Click @84 and read top to bottom: it is simply a timeline. Two writes in scenario 3a's world (edit + marker); one write here.
