5b43e57efa actualbudget: use internal ClusterIP for http-api server URL
The http-api sidecar was connecting to the public URL
(https://budget-*.viktorbarzin.me) which goes through Traefik/Authentik.
When pods got rescheduled to different nodes, this caused ETIMEDOUT errors.

Changed to internal service URL (http://budget-*.actualbudget.svc.cluster.local)
which is fast and reliable regardless of pod placement.

ee39dd2fc9 feat(storage): migrate 12 SQLite NFS PVCs to proxmox-lvm (Wave 1)
Add proxmox-lvm PVCs with pvc-autoresizer annotations for all
SQLite-backed services. Deployments updated to use new block storage
PVCs. Old NFS modules retained for 1-week rollback.

Services: ntfy, freshrss, insta2spotify, actualbudget (x3),
wealthfolio, navidrome (DB only), audiobookshelf config,
headscale, forgejo, uptime-kuma.

Also: set Recreate strategy on ntfy, forgejo, insta2spotify,
wealthfolio (required for RWO volumes).

1639910043 ingress latency: add histogram buckets, fix restarts, right-size memory
- Traefik: add fine-grained Prometheus histogram buckets (0.01-30s) for meaningful P50/P99
- Calibre: relax liveness probe (timeout 5→10s, threshold 3→6) to stop NFS-caused restarts
- Novelapp: increase memory 128Mi/256Mi → 640Mi/640Mi (confirmed OOMKilled, VPA upper 505Mi)
- Forgejo: increase memory 256Mi → 384Mi (at 80% of limit, VPA upper 311Mi)
- ActualBudget: add explicit resources to prevent silent LimitRange defaults
- Docs: update Nextcloud note from 4Gi → 8Gi limit (Apache spike history)

c103a1ee05 fix OOMKilled containers: bump immich/actualbudget memory, disable changedetection, cap clickhouse
- immich-server: 512Mi/1Gi → 1700Mi/1700Mi (VPA upperBound 1.39Gi, 34 OOM restarts)
- actualbudget http-api: 384Mi → 768Mi (VPA upperBound 615Mi, 3 OOM restarts)
- changedetection: replicas 1 → 0 (chronic OOM at 64Mi, not worth memory cost)
- rybbit clickhouse: add ConfigMap capping max_server_memory_usage to 800Mi (within 1Gi limit)

n8n: 768Mi → 1Gi (18 restarts, VPA upper ~765Mi)
Dawarich: 768Mi → 896Mi (2 restarts, VPA upper ~628Mi)
Traefik: 384Mi → 768Mi (2 restarts, VPA upper ~584Mi)

23019da8e5 equalize memory req=lim across 70+ containers using Prometheus 7d max data
After node2 OOM incident, right-size memory across the cluster by setting
requests=limits based on max_over_time(container_memory_working_set_bytes[7d])
with 1.3x headroom. Eliminates ~37Gi overcommit gap.

Categories:
- Safe equalization (50 containers): set req=lim where max7d well within target
- Limit increases (8 containers): raise limits for services spiking above current
- No Prometheus data (12 containers): conservatively set lim=req
- Exception: nextcloud keeps req=256Mi/lim=8Gi due to Apache memory spikes

Also increased dbaas namespace quota from 12Gi to 16Gi to accommodate mysql
4Gi limits across 3 replicas.

b00f810d3d Remove all CPU limits cluster-wide to eliminate CFS throttling
CPU limits cause CFS throttling even when nodes have idle capacity.
Move to a request-only CPU model: keep CPU requests for scheduling
fairness but remove all CPU limits. Memory limits stay (incompressible).

Changes across 108 files:
- Kyverno LimitRange policy: remove cpu from default/max in all 6 tiers
- Kyverno ResourceQuota policy: remove limits.cpu from all 5 tiers
- Custom ResourceQuotas: remove limits.cpu from 8 namespace quotas
- Custom LimitRanges: remove cpu from default/max (nextcloud, onlyoffice)
- RBAC module: remove cpu_limits variable and quota reference
- Freedify factory: remove cpu_limit variable and limits reference
- 86 deployment files: remove cpu from all limits blocks
- 6 Helm values files: remove cpu under limits sections

6bd3970579 [ci skip] add Homepage gethomepage.dev annotations to all services
Add Kubernetes ingress annotations for Homepage auto-discovery across
~88 services organized into 11 groups. Enable serviceAccount for RBAC,
configure group layouts, and add Grafana/Frigate/Speedtest widgets.

1f2c1ca361 [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.

220aa739ce [ci skip] migrate servarr sub-stacks + actualbudget factory NFS to CSI PV/PVC
Final batch: servarr (aiostreams, listenarr, readarr, soulseek,
prowlarr, qbittorrent, lidarr) and actualbudget factory.
All use ../../../modules/kubernetes/nfs_volume (3 levels deep).

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

c7c7047f1c [ci skip] Flatten module wrappers into stack roots
Remove the module "xxx" { source = "./module" } indirection layer
from all 66 service stacks. Resources are now defined directly in
each stack's main.tf instead of through a wrapper module.

- Merge module/main.tf contents into stack main.tf
- Apply variable replacements (var.tier -> local.tiers.X, renamed vars)
- Fix shared module paths (one fewer ../ at each level)
- Move extra files/dirs (factory/, chart_values, subdirs) to stack root
- Update state files to strip module.<name>. prefix
- Update CLAUDE.md to reflect flat structure

Verified: terragrunt plan shows 0 add, 0 destroy across all stacks.
