• A destroyed NPC hull leaves a hulk where it died: its own hull in sections, each holding plate and parts.
• The bridge section holds the flight recorder; the hold keeps a share of the cargo aboard.
• Kills by the pilot, port guns, guard and company drones, other hulls and staged ambushes all leave one.
• Hulks can be locked, matched, anchored to a waypoint and assayed with SCAN.
• Hulks near a world keep station with it; a hulk lasts 90 minutes and the sky keeps at most 48.

No Sol reset or save migration is required. Hulks are not saved or shared between players yet. Cutting, hulk-bound contracts, salvage rights and derelicts remain future work; Salvage readiness is unchanged.
