-| **Grafana `grafana.ini` + datasources** | atc-grafana | Monitoring as code |
-| **Kibana / ES keystore note** | atc-elastic01 | Passwords in keystore — document enrollment, not files |
-| **Proxmox VM notes** | pve01 | VMID → hostname → IP table (API export script) |
-| **Backup script** | docker01 | Nightly `git pull` + volume tarballs to ObjectScale |
 
-## Medium priority
+- [ ] Kibana `kibana.yml` export
-
+- [ ] TLS certificates inventory (NPM letsencrypt paths)
-| Item | Host | Why |
+- [ ] Automated weekly git commit via cron (install from `scripts/cron/README.md`)
-|------|------|-----|
+- [ ] Vault/external secrets instead of redacted files
-| **Spark jobs** | atc-lake01 | `/opt/spark-jobs/` in git |
+- [ ] Reach remaining hosts: `10.0.21.52`, `.37`, `.38` (no SSH key yet)
-| **Airflow `dags/scripts/`** | atc-airflow01 | Supporting Python for DAGs |
-| **Nginx Proxy Manager** | atc-mgt01 | Export NPM config (if used for TLS) |
-| **LDAP/LDIF exports** | atc-mgt01 | `*.ldif` already on host — useful for LDAP rebuild |
-| **MinIO / S3 buckets** | objectscale | Bucket layout + IAM policy docs |
-| **Network diagram** | docs | VLAN / firewall rules (10.0.10/20/21.x) |
-
-## Automation
-
-| Item | Description |
-|------|-------------|
-| **CI on Forgejo** | Lint YAML, validate compose, dry-run `docker compose config` |
-| **Ansible playbook** | `ansible-playbook deploy-lakehouse.yml` from git |
-| **Health check script** | Cron: curl all `siteMonitor` URLs, alert via Grafana |
-| **Monthly collect cron** | `collect-fleet-config.sh` + auto-commit branch |
-
-## Security hardening (lab → prod path)
-
-- Move all secrets to `.env` / Vault; git only `*.example`
-- Rotate `atc_cluster` SSH key periodically
-- Restrict ObjectScale `management_clients` from `0.0.0.0/0`
-- Enable TLS on Kafka (`SASL_SSL`) if exposed beyond lab VLAN
-
-## Dashboard enhancements
-
-- Homepage widget: link to architecture diagram in header logo
-- Add **DOCS** tab with bookmarks to all `docs/*.md` on Forgejo
-- Version badge in footer (git commit SHA from build arg)
