pub fn touch_for_attribute_change(item: &mut Item, by: &str)Expand description
Record an attribute-level mutation on an item. Sets updated /
updated_by for sort recency AND appends an entry to history for
the audit footer. Use this whenever you mutate an item attribute
(status, priority, deps, assignee, edit, …). Do NOT use it for
comment add / edit / rm; those use touch_for_comment_change
instead, because per-comment audit lives on the comment itself.
