+### Trust Levels
+
+FlaskPaste distinguishes three trust levels:
+
+| Level | Description | Default Expiry |
+|-------|-------------|----------------|
+| Anonymous | No certificate | 1 day |
+| Untrusted | Valid certificate, not registered via PKI | 7 days |
+| Trusted | Certificate registered via `/register` endpoint | 30 days |
+
 Authenticated users can:
 - Upload larger pastes (50 MiB vs 3 MiB)
 - Delete their own pastes
+- List their own pastes
+
+**Admin users** (first user to register via PKI) can additionally:
+- List all pastes (`GET /pastes?all=1`)
+- Delete any paste
