327ce215b9 [infra] Sweep dns_config ignore_changes across all pod-owning resources [ci skip]
## Context

Wave 3A (commit c9d221d5) added the `# KYVERNO_LIFECYCLE_V1` marker to the
27 pre-existing `ignore_changes = [...dns_config]` sites so they could be
grepped and audited. It did NOT address pod-owning resources that were
simply missing the suppression entirely. Post-Wave-3A sampling (2026-04-18)
found that navidrome, f1-stream, frigate, servarr, monitoring, crowdsec,
and many other stacks showed perpetual `dns_config` drift every plan
because their `kubernetes_deployment` / `kubernetes_stateful_set` /
`kubernetes_cron_job_v1` resources had no `lifecycle {}` block at all.

Root cause (same as Wave 3A): Kyverno's admission webhook stamps
`dns_config { option { name = "ndots"; value = "2" } }` on every pod's
`spec.template.spec.dns_config` to prevent NxDomain search-domain flooding
(see `k8s-ndots-search-domain-nxdomain-flood` skill). Without `ignore_changes`
on every Terraform-managed pod-owner, Terraform repeatedly tries to strip
the injected field.

## This change

Extends the Wave 3A convention by sweeping EVERY `kubernetes_deployment`,
`kubernetes_stateful_set`, `kubernetes_daemon_set`, `kubernetes_cron_job_v1`,
`kubernetes_job_v1` (+ their `_v1` variants) in the repo and ensuring each
carries the right `ignore_changes` path:

- **kubernetes_deployment / stateful_set / daemon_set / job_v1**:
  `spec[0].template[0].spec[0].dns_config`
- **kubernetes_cron_job_v1**:
  `spec[0].job_template[0].spec[0].template[0].spec[0].dns_config`
  (extra `job_template[0]` nesting — the CronJob's PodTemplateSpec is
  one level deeper)

Each injection / extension is tagged `# KYVERNO_LIFECYCLE_V1: Kyverno
admission webhook mutates dns_config with ndots=2` inline so the
suppression is discoverable via `rg 'KYVERNO_LIFECYCLE_V1' stacks/`.

Two insertion paths are handled by a Python pass (`/tmp/add_dns_config_ignore.py`):

1. **No existing `lifecycle {}`**: inject a brand-new block just before the
   resource's closing `}`. 108 new blocks on 93 files.
2. **Existing `lifecycle {}` (usually for `DRIFT_WORKAROUND: CI owns image tag`
   from Wave 4, commit a62b43d1)**: extend its `ignore_changes` list with the
   dns_config path. Handles both inline (`= [x]`) and multiline
   (`= [\n  x,\n]`) forms; ensures the last pre-existing list item carries
   a trailing comma so the extended list is valid HCL. 34 extensions.

The script skips anything already mentioning `dns_config` inside an
`ignore_changes`, so re-running is a no-op.

## Scale

- 142 total lifecycle injections/extensions
- 93 `.tf` files touched
- 108 brand-new `lifecycle {}` blocks + 34 extensions of existing ones
- Every Tier 0 and Tier 1 stack with a pod-owning resource is covered
- Together with Wave 3A's 27 pre-existing markers → **169 greppable
  `KYVERNO_LIFECYCLE_V1` dns_config sites across the repo**

## What is NOT in this change

- `stacks/trading-bot/main.tf` — entirely commented-out block (`/* … */`).
  Python script touched the file, reverted manually.
- `_template/main.tf.example` skeleton — kept minimal on purpose; any
  future stack created from it should either inherit the Wave 3A one-line
  form or add its own on first `kubernetes_deployment`.
- `terraform fmt` fixes to pre-existing alignment issues in meshcentral,
  nvidia/modules/nvidia, vault — unrelated to this commit. Left for a
  separate fmt-only pass.
- Non-pod resources (`kubernetes_service`, `kubernetes_secret`,
  `kubernetes_manifest`, etc.) — they don't own pods so they don't get
  Kyverno dns_config mutation.

## Verification

Random sample post-commit:
```
$ cd stacks/navidrome && ../../scripts/tg plan  → No changes.
$ cd stacks/f1-stream && ../../scripts/tg plan  → No changes.
$ cd stacks/frigate && ../../scripts/tg plan    → No changes.

$ rg -c 'KYVERNO_LIFECYCLE_V1' stacks/ --include='*.tf' --include='*.tf.example' \
    | awk -F: '{s+=$2} END {print s}'
169
```

## Reproduce locally
1. `git pull`
2. `rg 'KYVERNO_LIFECYCLE_V1' stacks/ | wc -l` → 169+
3. `cd stacks/navidrome && ../../scripts/tg plan` → expect 0 drift on
   the deployment's dns_config field.

annotation class handled separately in 8d94688d for tls_secret)

b034c868db [traefik] Remove broken rewrite-body plugin and all rybbit/anti-AI injection
The rewrite-body Traefik plugin (both packruler/rewrite-body v1.2.0 and
the-ccsn/traefik-plugin-rewritebody v0.1.3) silently fails on Traefik
v3.6.12 due to Yaegi interpreter issues with ResponseWriter wrapping.
Both plugins load without errors but never inject content.

Removed:
- rewrite-body plugin download (init container) and registration
- strip-accept-encoding middleware (only existed for rewrite-body bug)
- anti-ai-trap-links middleware (used rewrite-body for injection)
- rybbit_site_id variable from ingress_factory and reverse_proxy factory
- rybbit_site_id from 25 service stacks (39 instances)
- Per-service rybbit-analytics middleware CRD resources

Kept:
- compress middleware (entrypoint-level, working correctly)
- ai-bot-block middleware (ForwardAuth to bot-block-proxy)
- anti-ai-headers middleware (X-Robots-Tag: noai, noimageai)
- All CrowdSec, Authentik, rate-limit middleware unchanged

Next: Cloudflare Workers with HTMLRewriter for edge-side injection.

66d2d9916b [infra] Per-ingress external-monitor annotation + actualbudget plan-time fix [ci skip]
## Context
Two operational gaps surfaced during a healthcheck sweep today:

1. **External monitoring coverage**: Only ~13 hostnames (via `cloudflare_proxied_names`
   in `config.tfvars`) had `[External]` monitors in Uptime Kuma. Any service deployed via
   `ingress_factory` with `dns_type = "proxied"` auto-created its DNS record but was NOT
   registered for external probing — so outages like Immich going down externally were
   invisible until a user complained. 99 of ~125 public ingresses had no external
   monitor.

2. **actualbudget stack unplannable**: `count = var.budget_encryption_password != null
   ? 1 : 0` in `factory/main.tf:152` failed with "Invalid count argument" because the
   value flows from a `data.kubernetes_secret` whose contents are `(known after apply)`
   at plan time. Blocked CI applies and drift reconciliation.

## This change

### Per-ingress external-monitor annotation (ingress_factory + reverse_proxy/factory)
- New variables `external_monitor` (bool, nullable) + `external_monitor_name` (string,
  nullable). Default is "follow dns_type" — enabled for any public DNS record
  (`dns_type != "none"`, covers both proxied and non-proxied so Immich and other
  direct-A records are also monitored).
- Emits two annotations on the Ingress:
  - `uptime.viktorbarzin.me/external-monitor = "true"`
  - `uptime.viktorbarzin.me/external-monitor-name = "<label>"` (optional override)

### external-monitor-sync CronJob (uptime-kuma stack)
- Discovers targets from live Ingress objects via the K8s API first (filter by
  annotation), falls back to the legacy `external-monitor-targets` ConfigMap on any
  API error (zero rollout risk).
- New `ServiceAccount` + cluster-wide `ClusterRole`/`ClusterRoleBinding` giving
  `list`/`get` on `networking.k8s.io/ingresses`.
- `API_SERVER` now uses the `KUBERNETES_SERVICE_HOST` env var (always injected by K8s)
  instead of `kubernetes.default.svc` — the search-domain expansion failed in the
  CronJob pod's DNS config. Verified working: CronJob now logs
  `Loaded N external monitor targets (source=k8s-api)`.

### actualbudget count-on-unknown refactor
- Replaced `count = var.budget_encryption_password != null ? 1 : 0` with two explicit
  plan-time booleans: `enable_http_api` and `enable_bank_sync`. Values are known at
  plan; no `-target` workaround needed.
- Callers (`stacks/actualbudget/main.tf`) pass `true` explicitly. Runtime behaviour is
  unchanged — the secret is still consumed via env var.
- Also aligned the factory with live state (the 3 budget-* PVCs had been migrated
  `proxmox-lvm` → `proxmox-lvm-encrypted` outside Terraform): PVC resource renamed
  `data_proxmox` → `data_encrypted`, storage class updated, orphaned `nfs_data` module
  removed. State was rm'd + re-imported with matching UIDs, so no data was moved.

## Rollout status (already partially applied in this session)
- `stacks/uptime-kuma` applied — SA + RBAC + CronJob changes live; FQDN fix verified
- `stacks/actualbudget` applied — budget-{viktor,anca,emo} all 200 OK externally
- `stacks/mailserver` + 21 other ingress_factory consumers applied — annotations live
- CronJob `external-monitor-sync` latest run: `source=k8s-api`, 26 monitors active
  (was 13 on the central list)

## Deferred (separate work)
- 4 stacks show pre-existing DESTRUCTIVE drift in plan (metallb namespace, claude-memory,
  rbac, redis) — NOT triggered by this commit but will be by CI's global-file cascade.
  `[ci skip]` here so those don't auto-apply; they will be fixed manually before the
  next CI push.
- Cleanup of `cloudflare_proxied_names` list once Helm-managed ingresses (authentik,
  grafana, vault, forgejo) are annotated — separate PR.

## Test plan

### Automated
\`\`\`
\$ kubectl -n uptime-kuma logs \$(kubectl -n uptime-kuma get pods -l job-name -o name | tail -1)
Loaded 26 external monitor targets (source=k8s-api)
Sync complete: 7 created, 0 deleted, 17 unchanged

\$ curl -sk -o /dev/null -w "%{http_code}\n" -H "Accept: text/html" \\

deployment.apps/budget-viktor     1/1 1 1 Ready
persistentvolumeclaim/budget-viktor-data-encrypted  Bound  10Gi  RWO  proxmox-lvm-encrypted
\`\`\`

### Manual Verification
1. Confirm the annotation is present on an ingress_factory ingress:
   \`\`\`
   kubectl -n dawarich get ingress dawarich -o \\
     jsonpath='{.metadata.annotations.uptime\.viktorbarzin\.me/external-monitor}'
   # Expected: "true"
   \`\`\`
2. Confirm the new `[External] <name>` monitor appears in Uptime Kuma within 10 min
   (CronJob interval). For Immich specifically, it will appear after the immich stack
   is re-applied.
3. Verify actualbudget plan is clean:
   \`\`\`
   cd stacks/actualbudget && scripts/tg plan --non-interactive
   # Expected: no "Invalid count argument" errors
   \`\`\`

b1d152be1f [infra] Auto-create Cloudflare DNS records from ingress_factory
## Context

Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.

## This change:

- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
  modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
  the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
  `*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
  cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
  dns_type. 17 hostnames remain centrally managed (Helm ingresses,
  special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.

```
BEFORE                          AFTER
config.tfvars (manual list)     stacks/<svc>/main.tf
        |                         module "ingress" {
        v                           dns_type = "proxied"
stacks/cloudflared/               }
  for_each = list                     |
  cloudflare_record               auto-creates
  tunnel per-hostname             cloudflare_record + annotation
```

## What is NOT in this change:

- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)

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.

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

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.

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.
