e823b795f7 fix(dbaas,vault): fix backup CronJob failures and mysql-operator memory
- Add docker.io/library/ prefix to mysql and postgres backup images
  to satisfy Kyverno require-trusted-registries policy (both CronJobs
  were blocked for 46h, triggering MySQLBackupStale alert)
- Document mysql-operator chart ignoring resources values key — the
  LimitRange default (256Mi) was silently applied, putting the operator
  at 97% memory. Patched live to 512Mi via kubectl.
- Increase vault-raft-backup backoff_limit to 6 for transient failures
  (also fixed NFS export: vault-backup was a separate ZFS dataset not
  in the TrueNAS NFS share — destroyed dataset, created directory)

Traefik 502/503/504 responses. Adds catch-all IngressRoute (priority 1)
for 404 on unknown hosts. Only 5xx intercepted to avoid breaking JSON APIs.

Upstream v2.4.1 accidentally dropped idrac_power_supply_input_voltage from

Built a patched image that restores the single missing line:
  mc.NewPowerSupplyInputVoltage(ch, psu.LineInputVoltage, id)

9d87ce605f revert prometheus memory 3Gi→4Gi: WAL tmpfs shares cgroup limit
The 2Gi WAL tmpfs (medium: Memory) counts against the container's
memory limit. At 3Gi, Prometheus OOM-kills during WAL replay on
startup (heap + tmpfs > 3Gi). Reverting to 4Gi restores headroom.

12a51c4ffa right-size memory requests to unblock GPU workloads and fix dbaas quota [ci skip]
- nvidia: custom LimitRange (128Mi default, was 1Gi from Kyverno) to stop
  inflating GPU operator init containers; saves ~2.5Gi on GPU node
- nvidia: dcgm-exporter 1536Mi → 768Mi (actual usage 489Mi)
- monitoring: prometheus server 4Gi → 3Gi (actual usage 2.6Gi)
- onlyoffice: 2304Mi → 1536Mi (actual usage 1.3Gi)
- immich: frame explicit 64Mi resources (was getting 1Gi LimitRange default)
- dbaas: quota limits.memory 20Gi → 24Gi to fit 3rd MySQL replica

Root cause: Kyverno tier-2-gpu LimitRange injected 1Gi on every NVIDIA init
container (no explicit resources), wasting ~2.5Gi scheduling overhead on the
GPU node. Combined with over-requesting, frigate and immich-ml couldn't schedule.

73511b1230 extract remaining 19 modules from platform, complete stack split [ci skip]
Phase 3: all 27 platform modules now run as independent stacks.
Platform reduced to empty shell (outputs only) for backward compat

- real-estate-crawler: add vault-database ESO, use secret_key_ref in 3 deployments
- nextcloud: switch Helm chart to existingSecret for DB password
- grafana: add vault-database ESO, use envFromSecrets in Helm values
- woodpecker: use extraSecretNamesForEnvFrom, remove plan-time data source chain

fb66676d7b post-mortem: kured + containerd cascade outage — alerts + report
26h outage caused by unattended-upgrades kernel update → kured reboot →
containerd overlayfs snapshotter corruption → image pull failures →
calico down → cascading cluster outage.

Remediation:
- Add "Node Runtime Health" Prometheus alert group (6 alerts):
  KubeletImagePullErrors, KubeletPLEGUnhealthy, PodsStuckContainerCreating,
  KubeletRuntimeOperationsLatency, KubeletRunningContainersDrop, CalicoNodeNotReady
- Add containerd cascade inhibition rule
- Save post-mortem report as HTML in post-mortems/

Also applied via kubectl (needs Terraform codification):
- Sentinel gate DaemonSet gating kured reboots on cluster health
- Fixed kured Helm values: reboot window + gated sentinel path

- Add fallback field to all Slack receivers for clean push notifications
- Multiply ratio exprs by 100 for readable percentages
- Rename "New Tailscale client" to CamelCase "NewTailscaleClient"
- Add actionable hints to PodUnschedulable, NodeConditionBad, ForwardAuthFallbackActive

b2d07556d5 fix: migrate woodpecker database credentials to runtime-refreshed ExternalSecret
The woodpecker server was crashing repeatedly with database authentication failures
because Vault rotates the database password every 24 hours, but the Helm release
had hardcoded the password into WOODPECKER_DATABASE_DATASOURCE at plan time.

Changes:
- Updated ExternalSecret to provide the full DATABASE_DATASOURCE URI dynamically
- Modified Helm values to use envFrom to inject the secret instead of hardcoding
- ExternalSecret refreshes every 15 minutes, automatically picking up rotated passwords
- Pod will auto-restart when secret changes (via reloader.stakater.com annotation)
- This eliminates the plan-time password snapshot that goes stale within 24h

The pod still has an unrelated image pull issue on k8s-node4 (containerd blob
corruption), but the database credentials mechanism is now correctly implemented.
