• Keep a tracked vessel's speed, course, heading and fix time when AISStream static data arrives; the static message only merges name, type, destination and IMO (rudycelekli, #1351).
• Apply changed static metadata immediately, retaining known fields when a later static report omits them, without refreshing the vessel's position (samehkhamis, #1351).
