// The "空血条" root cause, pinned: an area actor projection is a kind-0 op9 carrying
// the ACTOR's party model. When the observer stands in that same ordinary party the
// record is the observer's own frame, and op153 is the only carrier of the per-member
// HP/MP rows (party.BuildSingleMemberRealtimeInfo) -- so the observer's frame must be
// closed with its own rows, not left on the bare op9.
