Created apps/pangolin/ directory with namespace.yaml defining the pangolin namespace.
Configured DNS A record for pangolin.basicstack.de → 178.105.17.239 (cluster ingress IP).
Updated DNS_REQUIREMENTS.md to document the new Pangolin service.
This completes Phase 1 of the Pangolin deployment (DEV-390):
- Repository structure created with namespace definition
- DNS record configured and verified in Hetzner zone
- Documentation updated

Created comprehensive network documentation for BasicStack k3s cluster:
- NETWORK_ARCHITECTURE.md: Complete network architecture with diagrams,
node configuration, CNI (Flannel) details, ingress/LoadBalancer setup,
DNS configuration, TLS certificates, network policies, traffic flows,
and troubleshooting procedures
- DNS_REQUIREMENTS.md: Complete DNS record requirements for all services
including A records, MX records, SPF, DKIM, DMARC, and PTR records
- NETWORK_VERIFICATION.md: Verification report documenting current state
of all network components with findings and recommendations
Updated infrastructure README with links to new network documentation.
Key findings:
- All worker nodes correctly configured with --node-ip set to private IPs
- Flannel VXLAN properly configured with public IP annotations
- Traefik ingress controller operational
- 16/17 TLS certificates valid (registry-tls needs investigation)
- 3 LoadBalancer services properly configured
- Network policies securing database services
Addresses DEV-225: Verify and document k3s cluster network configuration
Related: DEV-224 (node-ip configuration), DEV-223 (DNS issues)

Added Stakater Reloader to automatically restart Stalwart pods when
TLS certificates are renewed by cert-manager. This ensures seamless
certificate rotation without manual intervention.
Changes:
- Deploy Stakater Reloader in infrastructure/networking/
- Add Reloader annotation to Stalwart StatefulSet to watch stalwart-tls secret
- Document certificate renewal process and troubleshooting
The certificate is managed by cert-manager with Let's Encrypt and will
automatically renew 30 days before expiration (renewal date: 2026-08-20).
Reloader detects secret updates and triggers a rolling restart of the
Stalwart StatefulSet to load the new certificate.
