+### Risk Rule Properties (queried by Gremlin rules)
+
+| Property | Type | Source |
+|----------|------|--------|
+| `is_internet_exposed` | boolean | Collector derivation |
+| `crown_jewel` | boolean | `crown_jewel` tag |
+| `data_classification` | string | `data_classification` tag |
+| `env` | string | `env` or `environment` tag |
+| `is_publicly_accessible` | boolean | S3/RDS direct fetch |
+| `has_cross_account_trust` | boolean | IAM trust analysis |
+
+## Authentication
+
+- **Cognito User Pool** authenticates users
+- **Cognito Groups** (`khalifa-admin`, `khalifa-analyst`, `khalifa-viewer`) drive RBAC
+- **JWKS verification** in api-service via `jose`
+- **ALB OIDC** (EKS deployment) for browser-based UI auth; API service enforces JWT independently
+
+## Deployment Topologies
+
+| Topology | Use Case | Tradeoffs |
+|----------|----------|-----------|
+| **Lambda + Step Functions** | Small orgs, <50 accounts | Lower operational overhead |
+| **EKS + CronJob** | Large orgs, >50 accounts | Better scaling, more control |
