CONCLUSION: The 6.95× Energy-Mass Mismatch is 80% Measurement Artifact

The Problem:
• Baseline: Reaches 100% of target, uses 4.68 J total (1.12 J to reach + 3.56 J correcting overshoot)
• Adaptive (λ=40): Reaches only 20% of target, uses 0.95 J total (gives up before reaching target)
• Comparison is INVALID: We're comparing a successful system with a failed system
• When normalized: Baseline uses 4.68 J/unit progress, Adaptive uses 4.75 J/unit → LESS efficient!

Why λ_core=40 Fails:
• Creates effective mass ≈ 35× baseline (mass = 1 + 40 * 0.85)
• Reduces integration rate to 2.86% of baseline
• Core component can't accumulate enough control authority to reach target
• System is over-damped to the point of failure

The Hidden Opportunity (The Real "Free Lunch"):
• Baseline wastes 76% of energy correcting overshoot (3.56 J out of 4.68 J)
• Edge component (λ=0.05) shows genuine efficiency: 69% faster, 42% less energy, no failure
• Hypothesis: Moderate λ_core ≈ 2-5 could eliminate overshoot waste while still reaching target

Recommended Next Step:
Sweep λ_core from 0 to 10 to find "Goldilocks zone" where continuity tax creates genuine efficiency:
• Expected optimal at λ ≈ 2-5
• Should reach target (>95%) with 30-60% energy savings
• Savings from eliminating overshoot correction, not from task abandonment
