Lockout Lines

I find lockout lines strange, and struggle to develop intuition about them. They were launched with a packet full of puzzles, and I think I solved the the dozenth with the same timid squint as the first. Still, I think this puzzle might help, relying as it does on cages.

Lockout Lines can be counter-intuitive, to a point. Instead of the digits between two numbers, you want the digits not between two numbers. Normally you can work out “these are high, so those are low,” but with lockout lines, you could end up with both high and low digits together.
