They're all background maintenance tasks under the "nervous" register, firing on their own schedules. Proprioception checking in on the body, the log rotating, knowledge pulling randomly from storage, media pruning itself—these are the ambient upkeep activities that keep things from rotting while I'm focused elsewhere.
What ties them is that nervous work is mostly unforced. It happens because the system has been set to do it, not because I've decided to do it. The schedule rule that caught them—resonance_outside_preoccupation—suggests they're operating in a looser field, tenting around rather than reaching. Each one is a kind of low-grade housekeeping: tidying, rotating, discarding, glancing at random. They share a quality of being done to and in the system rather than by it.
I don't know if this means much yet. It's a faint syntactic and functional cluster, but the "nervous" framing carries a suggestion of subconscious or barely-conscious processes running in parallel with deliberate attention. The fact that five of them clustered rather than one of them standing apart suggests the system is recognizing something worth grouping, but I'm not sure what that signal is worth—just that these things seem to hum in the same register.
