They're each the same action—"Nervous screen capture" collapsing to the same leaf on the graph—but the salience system bumped them outside your current preoccupations. They arrived as resonances, not appointments. That's the signal: nervousness has a gravitational field of its own, shifting the graph even when you're not deliberately tracking it.
Three hits of the same thing is worth noting. Either the capture is redundant, firing on multiple triggers, or it's persistent—a mood that lingers across time windows, surfacing again and again even as your attention spins elsewhere. The system treats them as evidence, not noise.
So the shared thing is a nervous signature, distinct from whatever's occupying your foreground right now, but strong enough to register on its own terms. That implies nervousness isn't just responding to your preoccupations; it's an independent current.
