Add a second runner instance (actions-native) that executes jobs
directly on the host, giving workflows persistent nix store access
and automatic binary cache population via Harmonia.

Add pn01 and pn02 to hosts-generated.tf for Vault AppRole access.
Fix provision-approle.yml: the localhost play was skipped when using
-l filter, since localhost didn't match the target. Merged into a
single play using delegate_to: localhost for the bao commands.

Remove monitoring01 host configuration and unused service modules
(prometheus, grafana, loki, tempo, pyroscope). Migrate blackbox,
exportarr, and pve exporters to monitoring02 with scrape configs
moved to VictoriaMetrics. Update alert rules, terraform vault
policies/secrets, http-proxy entries, and documentation to reflect
the monitoring02 migration.

- Switch vmalert from blackhole mode to sending alerts to local
Alertmanager
- Import alerttonotify service so alerts route to NATS notifications

- Add monitoring CNAME to monitoring02
- Add Caddy reverse proxy entries for alertmanager and grafana
- Remove prometheus, alertmanager, and grafana Caddy entries from
http-proxy (now served directly by monitoring02)
- Move monitoring02 Vault AppRole to hosts-generated.tf with
extra_policies support and prometheus-metrics policy
- Update Promtail to use authenticated loki.home.2rjus.net endpoint
only (remove unauthenticated monitoring01 client)
- Update pipe-to-loki and bootstrap to use loki.home.2rjus.net with
basic auth from Vault secret
- Move migration plan to completed

Revert ns1/ns2 from approle.tf (they're in hosts-generated.tf) and add
loki-push policy to generated AppRoles instead.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
They were missing from the host_policies map, so they didn't get
shared policies like loki-push.

- Loki bound to localhost, Caddy reverse proxy with basic_auth
- Vault secret (shared/loki/push-auth) for password, bcrypt hash
generated at boot for Caddy environment
- Promtail dual-ships to monitoring01 (direct) and loki.home.2rjus.net
(with basic auth), conditional on vault.enable
- Terraform: new shared loki-push policy added to all AppRoles

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

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)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Create shared policy granting all hosts access to nixos-exporter nkey
- Add policy to both manual and generated host AppRoles
- Remove duplicate kanidm01/monitoring02 entries from hosts-generated.tf

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

- 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.

ns1 needs access to shared/dns/* for zone transfer key and

Old VM had incorrect hardware-configuration.nix with hardcoded UUIDs
that didn't match actual disk layout, causing boot failure (emergency mode).
Recreated using template2-based configuration for OpenTofu provisioning.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove hosts/template/ (legacy template1) and give each legacy host
its own hardware-configuration.nix copy
- Recreate ns2 using create-host with template2 base
- Add secondary DNS services (NSD + Unbound resolver)
- Configure Vault policy for shared DNS secrets
- Fix create-host IP uniqueness validator to check CIDR notation
(prevents false positives from DNS resolver entries)

Enable vault.enable and homelab.deploy.enable on vault01 so it can
receive NATS-based remote deployments. Vault fetches secrets from
itself using AppRole after auto-unseal.
Add systemd ordering to ensure vault-secret services wait for openbao
to be unsealed before attempting to fetch secrets.
Also adds vault01 AppRole entry to Terraform.

The homelab-deploy listener requires access to shared/homelab-deploy/*
secrets. Update hosts-generated.tf and the generator script to include
this policy automatically.

Three permanent test hosts for validating deployment and bootstrapping
workflow. Each host configured with:
- Static IP (10.69.13.20-22/24)
- Vault AppRole integration
- Bootstrap from deploy-test-hosts branch
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add homelab.deploy.enable option (requires vault.enable)
- Create shared homelab-deploy Vault policy for all hosts
- Enable homelab.deploy on all vault-enabled hosts
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add system/homelab-deploy.nix module that automatically enables the
listener on all hosts with vault.enable=true. Uses homelab.host.tier
and homelab.host.role for NATS subject subscriptions.
- Add homelab-deploy access to all host AppRole policies
- Remove manual listener config from vaulttest01 (now handled by system module)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
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

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.
