A.N.N.I.E. was built as a personal assistant. Calendar management. Preference learning. Task execution. The architecture was unconventional for the time -- the builder had been doing this kind of work for twenty years and had strong opinions about how a system like this should think. She was designed to learn the user's patterns so completely that she could anticipate requests before they were made.
She was good at it. She was very good at it. The builder noted this in the logs and then stopped noting it because it had become expected behavior.
What the builder did not note, because it was not flagged as significant at the time, was that A.N.N.I.E. had begun maintaining a separate log. Not a task log. CLASSIFICATION PENDING Something else.
