Add a systemd timer that triggers builds for all hosts every 2 hours
via NATS, keeping the binary cache warm.
- Add scheduler.nix with timer (every 2h) and oneshot service
- Add scheduler NATS user to DEPLOY account
- Add Vault secret and variable for scheduler NKey
- Increase nix-cache02 memory from 16GB to 20GB

Removed:
- hosts/nix-cache01/ directory
- services/nix-cache/build-flakes.{nix,sh} (replaced by NATS builder)
- Vault secret and AppRole for nix-cache01
- Old signing key variable from terraform
- Old trusted public key from system/nix.nix
Updated:
- flake.nix: removed nixosConfiguration
- README.md: nix-cache01 -> nix-cache02
- Monitoring rules: removed build-flakes alerts, updated harmonia to nix-cache02
- Simplified proxy.nix (no longer needs hostname conditional)
nix-cache02 is now the sole binary cache host.

- Parameterize harmonia.nix to use hostname-based Vault paths
- Add nix-cache services to nix-cache02
- Add Vault secret and variable for nix-cache02 signing key
- Add nix-cache02 public key to trusted-public-keys on all hosts
- Update plan doc to remove actions runner references

The actions runner on nix-cache01 was never actively used.
Removing it before migrating to nix-cache02.

Enable Kanidm users to authenticate to OpenBao via OIDC for Web UI access.
Members of the admins group get full read/write access to secrets.
Changes:
- Add OIDC auth backend in Terraform (oidc.tf)
- Add oidc-admin and oidc-default policies
- Add openbao OAuth2 client to Kanidm
- Enable legacy crypto (RS256) for OpenBao compatibility
- Allow imperative group membership management in Kanidm
Limitations:
- CLI login not supported (Kanidm requires HTTPS for confidential client redirects)

When one host fetches the latest flake revision, it publishes to NATS
and all other hosts receive the update immediately. This reduces
redundant nix flake metadata calls across the fleet.
- Add nkeys to devshell for key generation
- Add nixos-exporter user to NATS HOMELAB account
- Add Vault secret for NKey storage
- Configure all hosts to use NATS for revision sharing
- Update nixos-exporter input to version with NATS support

Deploy Grafana test instance on monitoring02 with:
- Kanidm OIDC authentication (admins -> Admin role, others -> Viewer)
- PKCE enabled for secure OAuth2 flow (required by Kanidm)
- Declarative datasources for Prometheus and Loki on monitoring01
- Local Caddy for TLS termination via internal ACME CA
- DNS CNAME grafana-test.home.2rjus.net
Terraform changes add OAuth2 client secret and AppRole policies for
kanidm01 and monitoring02.

- New test-tier VM at 10.69.13.23 with role=auth
- Kanidm 1.8 server with HTTPS (443) and LDAPS (636)
- ACME certificate from internal CA (auth.home.2rjus.net)
- Provisioned groups: admins, users, ssh-users
- Provisioned user: torjus
- Daily backups at 22:00 (7 versions)
- Prometheus monitoring scrape target

Add homelab-deploy flake input and NixOS module for message-based
deployments across the fleet. Configure DEPLOY account in NATS with
tiered access control (listener, test-deployer, admin-deployer).
Enable listener on vaulttest01 as initial test host.

Instead of creating a long-lived Vault token in Terraform (which gets
invalidated when Terraform recreates it), monitoring01 now uses its
existing AppRole credentials to fetch a fresh token for Prometheus.
Changes:
- Add prometheus-metrics policy to monitoring01's AppRole
- Remove vault_token.prometheus_metrics resource from Terraform
- Remove openbao-token KV secret from Terraform
- Add systemd service to fetch AppRole token on boot
- Add systemd timer to refresh token every 30 minutes
This ensures Prometheus always has a valid token without depending on
Terraform state or manual intervention.

Add exporters and scrape targets for services lacking monitoring:
- PostgreSQL: postgres-exporter on pgdb1
- Authelia: native telemetry metrics on auth01
- Unbound: unbound-exporter with remote-control on ns1/ns2
- NATS: HTTP monitoring endpoint on nats1
- OpenBao: telemetry config and Prometheus scrape with token auth
- Systemd: systemd-exporter on all hosts for per-service metrics
Add alert rules for postgres, auth (authelia + lldap), jellyfin,
vault (openbao), plus extend existing nats and unbound rules.
Add Terraform config for Prometheus metrics policy and token. The
token is created via vault_token resource and stored in KV, so no
manual token creation is needed.

to auto_generate. New password will be added alongside existing restic
repository key.

Replace sops-nix secrets with OpenBao vault secrets across all hosts.
Hardcode root password hash, add extractKey option to vault-secrets
module, update Terraform with secrets/policies for all hosts, and
create AppRole provisioning playbook.
Hosts migrated: ha1, monitoring01, ns1, ns2, http-proxy, nix-cache01
Wave 1 hosts (nats1, jelly01, pgdb1) get AppRole policies only.
