The branch control on user and consumed-steering bubbles could enable only when a completed turn ended with no node after the message at all, so readers saw a permanently unavailable control whose tooltip promised a state it could not reach. An enabled one would mislead anyway: a fork at a message seq cuts at the containing turn/end and takes the answer along, the opposite of the branch-to-re-ask reading a control on one's own bubble suggests. MessageItem loses its fork props, PendingSteeringBubble loses the showBranch special case, and messageBranchSeqs narrows to assistantBranchSeqs: only a completed turn's transcript tail that is the turn's own content-text assistant may fork. A steered turn keeps its fork point under the settled answer, because fork is a log-prefix cut and the steer is model-visible history the child inherits. Web aria goldens drop the user-bubble disabled-branch row and its hidden explanation text; the nested-subagent golden also loses the one enabled user-tail fork handle, a loss the decision note accepts.
