A link whose chain points at a network path is refused, a link pointing outside its own marketplace directory is refused, and directory listings skip links they cannot judge.\n\n**Details**\n\n- The check runs first on reads and on copy, move, write, truncate, chmod, delete, stat and digest.\n- Active only when the v5 storage backend is in use.\n\n**Evidence**\n\n`a link that leaves its marketplace tree is never followed`\n\n- Area: Plugins\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5"}
