# II. Module Mechanisms and Processes

For each Epoch (12 hours), RCM will automatically:

1. Record the latest Rebase Pool Balance and Last Epoch ROI
2. Calculate remaining Runway (unit: days)
3. Issue minting ratio adjustment recommendations to EM based on lifespan intervals

#### Minting Ratio Reference Table (set by DAO)

<table><thead><tr><th width="145">System Status</th><th width="237">Runway (governable threshold)</th><th>EM Minting Ratio (User : Pool, governable)</th></tr></thead><tbody><tr><td>Stable Zone</td><td>≥ 250 days</td><td>1 : 1</td></tr><tr><td>Warning Zone</td><td>180–249 days</td><td>1 : 2.5</td></tr><tr><td>Danger Zone</td><td>90–179 days</td><td>1 : 3.5</td></tr><tr><td>Critical Zone</td><td>&#x3C; 90 days</td><td>1 : 5 (maximum value, governable limit)</td></tr></tbody></table>
