Kept in this browser and written into the document above the derived sections, where an agent reads it as overriding them. This is the half you author — everything below the line is an observation, and observations are meant to be answerable.
Derived on this machine, from the vectors of the things you named, against the vocabulary each publisher declared with their own data. The question was never sent anywhere and no publisher was told you read them. Hand this file to any agent — the vector it describes is comparable against a catalogue you have never opened, because every corpus on this network embeds with the same model.
