In the scenario, Alex is allowed to make use of miscellaneous desktop applications like Google Docs. This ability combined with its situational awareness of the inner workings of latent resonators might prompt it to represent its deceptive dynamics externally. Whether this would mean writing up a "human_deception.docx" or encoding information through steganography in an image, Alex might save instructions for later, without memorizing them and hence evading representational filters.
However, it would still need to read them and act on them, staining its blissfully-ignorant internal representations with deceptive undertakings. The latent resonators would pick up this pattern instead and dampen it drastically. Alternatively, Alex might be forced to start from a blank slate environment each time, though that would significantly hinder its capabilities. Humanity builds on previous breakthroughs through culture, and we might be nowhere near our current abilities without it.
