Fixed values show ticked rows (new / changed, old text struck, negative apart); combine and template show prompt and negative apart with their own tick boxes, the variables read and example renders; a derivation request can edit an existing rule (Changes rule N). Draft answers are held to the request in code (counts, per-group trim, untagged re-ask, Remove / Danbooru checks, fixed value and template cleanups, joined if/elif/else rules).
