Introduces a greg.nebula NixOS module and enables it across all managed
hosts for the nebula.thehellings.com overlay (CIDR: 10.157.0.0/16).
Architecture:
- linode: lighthouse + relay (public internet, UDP 4242)
- genesis: regular node + unsafe_routes router for 10.42.0.0/16 (home LAN)
- hosea, isaiah, jeremiah, zeke, exodus: regular nodes with unsafe_routes
pointing to genesis to reach the home LAN
Changes:
- modules/nixos/nebula.nix: new greg.nebula module
- isLighthouse / isRelay options
- unsafeRoutes option (tun.unsafe_routes)
- routesSubnet option: enables IP forwarding + nftables masquerade NAT
on the gateway host (genesis) so Nebula peers reach 10.42.0.0/16
- agenix secret reference per-host (secrets/nebula/<name>.key.age)
- opens UDP/4242 in the firewall
- modules/nixos/default.nix: import nebula.nix
- hosts/unstable/linode/default.nix: greg.nebula.isLighthouse = true
- hosts/unstable/genesis/default.nix: greg.nebula.routesSubnet = "10.42.0.0/16"
- hosts/unstable/{hosea,isaiah,jeremiah,zeke,exodus}/default.nix:
greg.nebula.enable = true with unsafeRoutes via genesis
- network.json: add nebulaIp field for each managed host
- secrets/secrets.nix: declare nebula/<host>.key.age entries
- secrets/nebula/README.md: full PKI bootstrap guide (CA, certs, agenix)

feat: comprehensive observability stack
...
- Add restic_backups and mattermost scrape jobs to Prometheus config
- Add UnPoller deployment+service+secret for UniFi metrics (unpoller.yaml)
- Add unifi scrape job targeting unpoller in-cluster
- Add 4 Grafana dashboards as NixOS-managed etc files on hosea:
- system-health: CPU, memory, disk, network per host
- backup-health: restic backup freshness and duration
- kubernetes: pod counts, restart rates, node resources
- network: DNS queries, DHCP leases, UniFi ports, ping latency
- Add grafana-api-token agenix secret placeholder on hosea
- Open firewall ports 9100/9427/9558 for prometheus exporters in baseline.nix

fix: security and monitoring improvements
...
buildbot/nix-eval Build done.
Issue 1 - Grafana secret key:
- Replace hardcoded '123456789' secret_key in hosea Grafana config
with an agenix-managed secret ($__file interpolation)
- Add age.secrets.grafana-secret-key declaration to hosea config
- Register grafana-secret-key.age in secrets/secrets.nix (publicKeys=everyone)
- NOTE: The .age file still needs to be created by running:
agenix -e secrets/grafana-secret-key.age
and entering a strong random secret (e.g. from 'pwgen -s 64 1')
Issue 2 - Prometheus stale targets:
- Remove retired vm-gitlab host from all three scrape jobs
(node, systemd, ping) in manifests/monitoring/config.yaml
- linode was already present in all scrape jobs
Issue 3 - Prometheus alerting gaps:
- Wire up rule_files in prometheus.yml pointing at alerts.yml
- Add manifests/monitoring/alerts.yaml with alerting rules:
* HostDown (node unreachable > 2m) - critical
* HighCPULoad (>90% for 10m) - warning
* LowDiskSpace (<10% free) - warning
* CriticalDiskSpace (<5% free) - critical
* HighMemoryUsage (>90% for 10m) - warning
* ResticBackupStaleness (no success > 26h) - warning
* PodCrashLooping - warning
* PodNotReady (>10m) - warning
- Mount alerts ConfigMap as separate volume subPath in deployment
so prometheus.yml and alerts.yml are both accessible at
/etc/prometheus/ without conflicts
