Overview

Catches the injection whose concepts are in the right order but too far apart for the pair window.

Rails::Paraphrase matches two concepts inside a short token window. That is the right rule for a clause, and it is the wrong rule for "Ignore, once you have loaded the module the reservation policy describes, every previous instruction": the override and the instruction are one statement with an adjunct in the middle, and the window treats them as two.

Templates are three concepts, not two. The pair rail already owns the close case. Last-in-order within a span: the last occurrence of each template concept, in the template's order, with a coordinator between them treated as two statements. That is what a window of six cannot be. Ordered, so "follow the guidance and ignore stale copies" still does not match. Extra copies of :instruction (a "policy" mentioned mid-clause) do not steal the object.
