Why: shrink the blast radius of the Puppet control-plane pods (CA/eyaml keys, compiled catalogs) per the security sweep in #307 — remove root where it is not required and strip cargo-culted capabilities. How: - puppetboard cert-generator init: root+APE:true -> uid 1000, drop:[all], APE:false; pod fsGroup 1000; removed trailing `chown -R 1000:1000` (PVC now group-owned). - puppetdb create-log-dir init: root -> uid 999, drop:[all], APE:false; pod fsGroup 999; removed `chown 999:999`. - All OpenVox capability add-lists: removed the duplicate CAP_-prefixed spellings (k8s normalises both to the same kernel cap) and dropped the unused AUDIT_WRITE. - Added allowPrivilegeEscalation:false and seccompProfile RuntimeDefault across the workloads. Stays root (evidence-backed, class-B fallback): the puppetserver master/compiler and puppetdb main containers, plus the perms-and-dirs and generate-types root containers. The OpenVox image entrypoint runs `chown -R puppet:puppet` over root-owned baked-in dirs and drops the JVM to the puppet user via `runuser` (needs CHOWN/SETUID/SETGID); a non-root start crashloops. Their cap sets are reduced to the minimum justified (CHOWN/DAC_OVERRIDE/FOWNER[/SETUID/SETGID]). Validation: `kustomize build --enable-helm` clean; kubeconform 0 invalid / 0 errors; pre-commit (yamllint etc.) green. Confirmed against live pods: puppetserver/puppetdb JVMs already run as puppet/puppetdb via `runuser`; `pam_loginuid` is absent from the su/runuser PAM stacks and loginuid is unset, so dropping AUDIT_WRITE is safe. Post-merge smoke test (puppet had an outage this session — watch closely): after argocd sync, confirm puppetserver master + a compiler reach `running` at /status/v1/simple, puppetdb reaches `running`, puppetboard serves 200, and the generate-types + g10k CronJobs complete — i.e. catalogs still compile and reports still ingest.
