I've not enjoyed Lockout Lines so far as a general constraint, but I loved this puzzle. Well done!

Amended the English rules to clarify lockout line filling options, updated links to match.

Fantastic puzzle! The solve path is fun and smooth, and it demonstrated some of the key logic around both lockout lines and XVXV in a really nice way.
