- Generalized `isUserQueuedMessage` to a user-attribution predicate (`role === "user"` or custom `attribution === "user"` and not display-suppressed) so visible agent-authored steers (advisor cards, IRC/extension asides) and hidden goal/plan/budget steers are all excluded from editor restore, not just advisor cards.
- Gave `AgentSession.clearQueue` a `{ forInterrupt }` option: plain Alt+Up dequeue restores user messages and preserves every other queued message for the continuing stream, while Esc+abort keeps only advisor cards (for `abort()`'s `#extractQueuedAdvisorCards` preservation) and drops other internal steers so the post-abort `#drainStrandedQueuedMessages` can't auto-resume the interrupted run.
- Threaded `forInterrupt: options?.abort` from `InputController.restoreQueuedMessagesToEditor` and kept `queuedMessageCount` on actual displayable-queue semantics so `hasPendingMessages()`/RPC and the empty-submit abort gate stay accurate.
- Updated skill-queue tests to cover both policies (hidden and visible agent-authored steers preserved on dequeue, dropped on interrupt) and refreshed the changelog entry.
