What are content signals?

Content signals are a setting for each source, off by default. You’re asked at the moment you connect, upload, or read that source, and you can turn them off in settings at any time, which deletes what was derived from them. With content signals on, itogai reads the text once, in memory, to derive relationship signals, such as knowing that you and a contact talked about an intro, and then discards it. With them off, itogai only knows who you talked to, when, and how often. Email always stays at metadata only.
