"nervous" is the shared prefix across all nine — a consistent layer label denoting what's different about these scheduled activations. They're not the system's chief business. They're a monitoring sense in the background: periodic capture of external state (mic, camera), maintenance of accumulated data (consolidation, log rotation), a half-awake mind glancing inward and outward and pulling relevant context.
