Quantifying extraction, return viability, and regulatory harm

PERSEPHONE measures ecological cost, extraction velocity, and recovery probability — not just compliance. This dashboard compares the full system set side-by-side and surfaces actionable intervention levers.

Can it return?

Comparative Dashboard

Side-by-side metrics reveal where harm accumulates, how profit leaves, and whether recovery is mathematically plausible.

Values normalized across these systems

Regulatory Capture & Lag

Torres’s specialty: where enforcement fails, how long communities absorb harm before protections arrive, and which systems are locked into extraction.

Regulatory Capture Visuals

Enforcement Gap Heatmap

Revolving Door Network

Regulatory Lag Timeline

Visuals are derived from enforcement gap, moss density, and mycelial routing indicators in the verdicts. Replace with empirical datasets when available.

What-if Intervention Simulator

Adjust intervention levers to see how return viability responds. This simulation uses the engine’s return viability formula with explicit assumptions (see note below).

Assumptions: remediation rate directly scales return viability; moss reduction factor scales moss density (proxy for long-term harm). Enforcement gap reduction is modeled as a partial moss reduction (policy gains reduce chronic accumulation). Replace with empirical policy data when available.

Methodology Snapshot

  • Carrion Ledger: irreversible human + ecological cost per yield
  • Mycelial Routing: hidden profit extraction & insulation
  • Moss Model: chronic unremediated harm accumulation
  • Bloom Distortion: narrative vs substrate health gap
  • Seasonal Engine: return viability + descent probability
