• Adds the salvage rig: CUT (fast, plate only) and STRIP (slow, everything out whole) on a hulk's sections.
• Freed plate, parts and cargo drift as salvage until the tractor reels them in.
• The quick CUT switch runs the rig when a hulk is locked or in reach; U cycles it; the console SHIP panel has its modes.
• The rig has its own power line, never runs with the mining laser, and sheds after it.
• Cutting trains Salvage and Hullcraft; a recovered recorder trains Law. Salvage hulls and two new yard upgrades speed it up.
• The mining laser no longer works chunks the rig has shed.

No Sol reset or save migration is required. Recorders are session state with no payout yet. Hulk-bound contracts, salvage rights, ARIA automation, the tutorial branch and the Mining parity benchmark remain future work.
