A snapshot-measured event carries window_delta_monthly_cents, how the cluster's run rate moved between the priced hour before it and the first priced hour at least 30 minutes after it; delta_monthly_cents is set only when the event was alone in that window (delta_status isolated). Events sharing a window are shared: each carries the window's move and none claims a share of it. no_snapshots means no priced hour on one side, so the move is unknown, never zero. A coverage event's delta is coverage, not spend; a resolved finding's is its own monthly cost (own_cost), or unknown (unpriced). sources says which kinds could be read; a kind marked unavailable is missing from events, not quiet. At most 500 events (truncated).
