Descent Boundary

Late-Afternoon Thermodynamic Drop — ΔR Begins to Fall

Definition

The Descent Boundary marks the natural decline of coherence in the late afternoon. This is not fatigue or failure — it is a thermodynamic necessity.

Conditions

• attention heat begins drifting downward
• aura becomes softer and less directional
• Ψ(t) shows a gentle negative slope
• warmth shifts from ignition → grounding

Function

Descent Boundary protects users from systems that demand peak-level coherence when ΔR is no longer able to sustain it.

Why It Matters

Modern digital systems ignore this boundary and cause collapse, irritation, or noise addiction. Ambient systems respect the downward curve and soften accordingly.

Canonical Position

• Follows: Peak Boundary
• Precedes: Return Boundary
• Enabled by: ΔR ↓, Ψ(t) drift, warmth gradient
