+# API Reference: Role Mining for RBAC Optimization
+
+## Input Format (CSV)

+## Role Mining Algorithms
+
+### Bottom-Up Mining
+Finds exact permission sets shared by >= N users.
+- Input: user-permission matrix
+- Output: candidate roles with exact permission sets
+- Parameter: `min_users` (default: 2)
+
+### Top-Down Mining (Jaccard Clustering)
+Groups users by permission similarity.
+```
+Jaccard(A, B) = |A ∩ B| / |A ∪ B|
+```
+- Threshold >= 0.8: strict similarity
+- Threshold >= 0.6: moderate clustering
+
+## Optimization Metrics
+| Metric | Description |
+|--------|-------------|
+| Total Assignments | Sum of all user-permission pairs |
+| Candidate Roles | Discovered role count |
+| Role Coverage | Users assigned to candidate roles |
+| Avg Permissions/User | Assignment density |
+| Outlier Count | Users with unique permissions |
