 ## 2.9. UFW Hardening
 
 * **Description**: Defaults to `deny incoming` and (optionally) `deny outgoing`; automatically opens only whitelisted ports.
+* **Primordial SSH exception**: `--primordial-url <https-git-url>`, `--primordial-key <ssh-identity-filename>` and
+  `--primordial-ssh <port>` configure the CDI Primordial overlay clone. `--primordial-ssh` also adds an outgoing-only UFW TCP
+  exception for a bootstrap/recovery SSH port when the live system's UFW outgoing policy is `deny`. It adds no incoming firewall
+  rule and does not replace `--ssh-port`. If the requested port already matches an existing outgoing SSH exception, the current
+  hook still emits the requested labelled rule because this repository has no separate UFW rule deduplication layer.
 * **Rationale**: Implements a default-deny firewall, reducing lateral movement and data exfiltration risks immediately after
   deployment.

+  --primordial-key <ssh-identity-filename>
