Three questions, answered daily. Each one captures a different aspect of Fatigue Vulnerability — how cognitive depletion is affecting your decision-making right now.
Fatigue doesn't just make you tired. It narrows attention, lowers skepticism, and makes you more likely to comply with requests you'd normally question. The Pulse tracks that in real time so the system knows when your risk window is open.
How clear were your priorities today?
FV · CLARITY INDEX
Measures whether cognitive load has fragmented your focus. Scattered priorities are an early signal of fatigue accumulation.
Did anything feel urgent that wasn't planned?
FV · URGENCY INTRUSION
Tracks unplanned urgency — a key attack surface. Fatigued people process urgency as real, which is exactly what social engineering exploits.
How much capacity do you have left right now?
FV · RESIDUAL CAPACITY
Your remaining mental bandwidth. Low capacity suppresses verification instincts — you're more likely to approve, comply, or click without checking.
Signal recorded.
Each bar is your fatigue signal for that day, built from how your three check-in responses combined. Baseline Drift compares your recent average to your established baseline — a rising drift means your susceptibility window is opening and the system will flag it.
The Drift Engine watches for meaningful movement away from your behavioral baseline. A single elevated day is noise. A pattern across check-ins is signal. When fatigue scores shift consistently upward, your susceptibility rises — and the engine flags it before it becomes a problem.
It's the analytical layer between your daily check-in and your weekly briefing. It decides when current conditions are significant enough to warrant attention and action.
