exclude nextcloud from HighServiceErrorRate alert
Nextcloud has chronic 5xx errors due to SQLite lock contention causing
Apache worker exhaustion. Excluding from alert until MySQL migration.

fix noisy JobFailed and duplicate mail server alerts
- JobFailed: only alert on jobs started within the last hour, so stale
  failed CronJob runs don't keep firing after subsequent runs succeed
- Mail server alert: renamed to MailServerDown, now targets the specific
  mailserver deployment instead of all deployments in the namespace
  (was falsely triggering on roundcubemail going down)
- Updated inhibition rule to use new MailServerDown alert name

reduce alert noise: add cascade inhibitions, increase for durations, drop Loki alerts
- NodeDown now suppresses workload and service alerts (PodCrashLooping,
  DeploymentReplicasMismatch, StatefulSetReplicasMismatch, etc.)
- NFSServerUnresponsive suppresses pod-level alerts
- Increased for durations on transient alerts (e.g. 15m→30m for replica mismatches)
- NodeDown for: 1m→3m to avoid flapping
- Removed all 3 Loki log-based alerts (duplicated Prometheus alerts)
- Downgraded HeadscaleDown critical→warning, mail server page→warning

resource quota review: fix OOM risks, close quota gaps, add HA protections
Phase 1 - OOM fixes:
- dashy: increase memory limit 512Mi→1Gi (was at 99% utilization)
- caretta DaemonSet: set explicit resources 300Mi/512Mi (was at 85-98%)
- mysql-operator: add Helm resource values 256Mi/512Mi, create namespace
  with tier label (was at 92% of LimitRange default)
- prowlarr, flaresolverr, annas-archive-stacks: add explicit resources
  (outgrowing 256Mi LimitRange defaults)
- real-estate-crawler celery: add resources 512Mi/3Gi (608Mi actual, no
  explicit resources)

Phase 2 - Close quota gaps:
- nvidia, real-estate-crawler, trading-bot: remove custom-quota=true
  labels so Kyverno generates tier-appropriate quotas
- descheduler: add tier=1-cluster label for proper classification

Phase 3 - Reduce excessive quotas:
- monitoring: limits.memory 240Gi→64Gi, limits.cpu 120→64
- woodpecker: limits.memory 128Gi→32Gi, limits.cpu 64→16
- GPU tier default: limits.memory 96Gi→32Gi, limits.cpu 48→16

Phase 4 - Kubelet protection:
- Add cpu: 200m to systemReserved and kubeReserved in kubelet template

Phase 5 - HA improvements:
- cloudflared: add topology spread (ScheduleAnyway) + PDB (maxUnavailable:1)
- grafana: add topology spread + PDB via Helm values
- crowdsec LAPI: add topology spread + PDB via Helm values
- authentik server: add topology spread via Helm values
- authentik worker: add topology spread + PDB via Helm values

[ci skip] fix broken Homepage widgets + add service API tokens to SOPS
- Grafana: fix service URL (grafana not monitoring-grafana)
- Uptime Kuma: remove widget (no status page configured)
- Speedtest/Frigate/Immich: use internal k8s service URLs (external
  goes through Authentik forward auth, blocking API calls)
- pfSense: clean up annotations
- SOPS: add headscale, prowlarr, changedetection, audiobookshelf tokens

[ci skip] phase 5+6: update CI pipelines for SOPS, add sensitive=true to secret vars
Phase 5 — CI pipelines:
- default.yml: add SOPS decrypt in prepare step, change git add . to
  specific paths (stacks/ state/ .woodpecker/), cleanup on success+failure
- renew-tls.yml: change git add . to git add secrets/ state/

Phase 6 — sensitive=true:
- Add sensitive = true to 256 variable declarations across 149 stack files
- Prevents secret values from appearing in terraform plan output
- Does NOT modify shared modules (ingress_factory, nfs_volume) to avoid
  breaking module interface contracts

Note: CI pipeline SOPS decryption requires sops_age_key Woodpecker secret
to be created before the pipeline will work with SOPS. Until then, the old
terraform.tfvars path continues to function.

[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).

- Kyverno reports controller: 128Mi req / 512Mi limit (was 128Mi Helm default)

[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.

[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

fix: use plain string for cache_from/cache_to and fix caretta helm_release
- cache_from/cache_to must be plain strings, not YAML lists — the
  plugin-docker-buildx treats them as single string values and the
  Woodpecker settings layer was splitting comma-separated list items
  into separate --cache-from flags (type=registry and ref=... separately)
- caretta.tf: replace deprecated set{} blocks with values=[yamlencode()]
  to fix Terraform plan error with newer Helm provider

[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

[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.
