614d14c47d [ci skip] expand Prometheus PVC to 200Gi, increase retention to 180GB for 1-year history 
Storage analysis: ~10.5 GB/month ingestion rate, 1 year = ~125 GB + overhead.
PVC: 30Gi → 200Gi, retention.size: 45GB → 180GB.
Historical TSDB data restored from NFS (39.8 GB total including all blocks).

100a876dfe [ci skip] migrate Redis, Prometheus, Loki storage to iSCSI 
- Redis: local-path → iscsi-truenas (master + replica persistence)
- Prometheus: NFS PV+PVC → dynamic iSCSI PVC (prometheus-data)
- Loki: NFS PV → dynamic iSCSI via storageClass in Helm values
- Deleted 2 orphaned Released iSCSI PVs (31Gi freed)

307b356f06 [ci skip] fix: add mount_options to all NFS PVs (soft,timeo=30,retrans=3) 
Critical fix: StorageClass mountOptions only apply during dynamic
provisioning. Our static PVs (created by Terraform) were missing
mount_options, so all NFS mounts defaulted to hard,timeo=600 —
the exact stale mount behavior we were trying to eliminate.

Adds mount_options directly to the nfs_volume module PV spec and
to the monitoring PVs (prometheus, loki, alertmanager).

Requires re-applying all stacks to propagate to existing PVs.

0abae33c71 [ci skip] complete NFS CSI migration: complex stacks + platform modules 
Migrate remaining multi-volume stacks and all platform modules from
inline NFS volumes to CSI-backed PV/PVC with nfs-truenas StorageClass
(soft,timeo=30,retrans=3 mount options).

Complex stacks: openclaw (4 vols), immich (8 vols), frigate (2 vols),
nextcloud (2 vols + old PV replaced), rybbit (1 vol)

Remaining stacks: affine, ebook2audiobook, f1-stream, osm_routing,
real-estate-crawler

Platform modules: monitoring (prometheus, loki, alertmanager PVs
converted from native NFS to CSI), redis, dbaas, technitium,
headscale, vaultwarden, uptime-kuma, mailserver, infra-maintenance

89a6e08245 [ci skip] Infrastructure hardening: security, monitoring, reliability, maintainability 
Phase 1 - Critical Security:
- Netbox: move hardcoded DB/superuser passwords to variables
- MeshCentral: disable public registration, add Authentik auth
- Traefik: disable insecure API dashboard (api.insecure=false)
- Traefik: configure forwarded headers with Cloudflare trusted IPs

Phase 2 - Security Hardening:
- Add security headers middleware (HSTS, X-Frame-Options, nosniff, etc.)
- Add Kyverno pod security policies in audit mode (privileged, host
  namespaces, SYS_ADMIN, trusted registries)
- Tighten rate limiting (avg=10, burst=50)
- Add Authentik protection to grampsweb

Phase 3 - Monitoring & Alerting:
- Add critical service alerts (PostgreSQL, MySQL, Redis, Headscale,
  Authentik, Loki)
- Increase Loki retention from 7 to 30 days (720h)
- Add predictive PV filling alert (predict_linear)
- Re-enable Hackmd and Privatebin down alerts

Phase 4 - Reliability:
- Add resource requests/limits to Redis, DBaaS, Technitium, Headscale,
  Vaultwarden, Uptime Kuma
- Increase Alloy DaemonSet memory to 512Mi/1Gi

Phase 6 - Maintainability:
- Extract duplicated tiers locals to terragrunt.hcl generate block
  (removed from 67 stacks)
- Replace hardcoded NFS IP 10.0.10.15 with var.nfs_server (114
  instances across 63 files)
- Replace hardcoded Redis/PostgreSQL/MySQL/Ollama/mail host references
  with variables across ~35 stacks
- Migrate xray raw ingress resources to ingress_factory modules

e6420c7b36 [ci skip] Move Terraform modules into stack directories 
Move all 88 service modules (66 individual + 22 platform) from
modules/kubernetes/<service>/ into their corresponding stack directories:

- Service stacks: stacks/<service>/module/
- Platform stack: stacks/platform/modules/<service>/

This collocates module source code with its Terragrunt definition.
Only shared utility modules remain in modules/kubernetes/:
ingress_factory, setup_tls_secret, dockerhub_secret, oauth-proxy.

All cross-references to shared modules updated to use correct
relative paths. Verified with terragrunt run --all -- plan:
0 adds, 0 destroys across all 68 stacks.
