+
+### 1. **Automatic Grant Renewal**
+- Seamless transition from completed grants to new funding cycles
+- Performance-based eligibility criteria
+- Configurable renewal parameters (amount, duration)
+- Automatic stream initialization upon approval
+
+### 2. **14-Day DAO Veto Period**
+- Community oversight before renewal execution
+- Configurable veto thresholds (default: 20%)
+- Transparent veto voting with reasons
+- Emergency termination capabilities
+
+### 3. **Job Security Framework**
+- Critical infrastructure designation for essential projects
+- Performance-based eligibility scoring
+- Maximum renewal cycle limits (default: 10 cycles)
+- Continuous contribution tracking
+
+### 4. **Performance Metrics Integration**
+- Comprehensive performance evaluation system
+- Multi-dimensional scoring (completion, quality, innovation)
+- Community satisfaction tracking
+- Technical excellence assessment

+    code_quality_score: 90,
+    documentation_quality: 85,
+    collaboration_score: 88,

+};
+
+let proposal_id = recursive_funding.propose_renewal(
+    original_grant_id,
+    100000i128,    // Renewal amount
+    12,              // 12-month renewal
+    "Excellent performance with critical infrastructure impact",
+    performance_metrics,
+)?;
+```
+
+### 3. Cast Veto Vote
