+## Related Project: indieweb2-bastion
+
+The [indieweb2-bastion](https://github.com/hyperpolymath/indieweb2-bastion) repository provides infrastructure-layer security that complements php-aegis and sanctify-php at the application layer.
+
+### What indieweb2-bastion Does
+
+| Feature | Purpose |
+|---------|---------|
+| Hardened bastion ingress | Secure network entry points |
+| Oblivious DNS (IPv6) | Privacy-preserving DNS resolution |
+| GraphQL DNS APIs | Programmable domain resolution |
+| SurrealDB provenance graphs | Audit trails & data lineage |
+
+### Relationship to IndieWeb Security
+
+While **not** implementing IndieWeb protocols (Micropub, IndieAuth, Webmention), indieweb2-bastion provides foundational security patterns applicable to IndieWeb infrastructure:
+
+| indieweb2-bastion | IndieWeb Application |
+|-------------------|---------------------|
+| Provenance graphs | Track Webmention verification chains |
+| Audit capabilities | Log IndieAuth token usage |
+| Bastion pattern | Rate limit Webmention endpoints |
+| Policy controls (Nickel) | Define allowed Micropub content |
+

+### Related Project: indieweb2-bastion
+
+The [indieweb2-bastion](https://github.com/hyperpolymath/indieweb2-bastion) repository provides infrastructure-layer security (bastion ingress, oblivious DNS, provenance graphs) that complements php-aegis at the application layer.

+
+**Lessons from indieweb2-bastion**:
+- Use provenance-style tracking for Webmention verification chains
+- Apply bastion patterns for rate limiting endpoints
+- Consider audit logging as a first-class feature
