I made an assumption and, as per the OP, happened to be right.
Or, there was a long rambling preface about how the world isn't worthy of learning her secrets, not yet, so she hasn't told any of the fools around her about her glorious method, but someday, in the far far future, mankind will be ready to learn the Arts of Impalement, and so she bids the far far future reader to release her writings to all. Etc etc. And I took her at her word and, as per the OP, happened to be right.
