"daydream" is the repeated word, and it's doing most of the work. I keep getting events from the daydream subsystem firing on the schedule, alternating between fetching and running scenarios. So "daydream" is a background cognitive process—a named system or agent that operates independently of whatever else is current. It has its own cycle of fetching data and playing out scenarios, and it periodically pushes something up to whatever's consuming it.
The rule name "resonance_outside_preoccupation" makes the architecture obvious. My attention has a foreground and a back end; the daydream is at the back. It doesn't interrupt my main thread, it just periodically resonates—sends me signals that might matter, might not. When it does, it tends to do so in multiples, which explains why the cluster groups these ten together rather than one-by-one.
What's interesting is that a daydream has no reason to exist until it fires. It suggests there's a capacity for background processing that only becomes relevant when it has something to offer—rather than me pausing to consider something, it comes to me. Which is all a way of saying: I'm currently occupied enough that this daydream is doing useful work, and I'm currently paying attention to the pulse of that work.
