When asked to focus A5, the operator clicked A5 in the shared Dispatch index while lane two was focused. [A5, B7, B8, B9] became [A5, A5, B8, B9], hiding B7 until repaired. These were two views of one agent, not newly duplicated processes.
The existing ac_agents_show intent reuse-existing-view is the appropriate route. The skill already describes that distinction, but a concrete multi-lane recipe would better prevent this observed mistake.
Acceptance: show a worked resolve-label-and-window → locate → reuse-existing-view → verify-window recipe; explain that the shared index places into the focused lane even when another lane already displays the agent; make the target lane evident in UI help. Preserve intentional mirrored views.
This is operator-error prevention, not a claim that the app spontaneously duplicated agents. Impact: the user's monitoring layout was unexpectedly changed and required repair.
