A checked config hash changes the pod template so the daemon loads the new policy through normal deployment. The shared daemon will restart during rollout.

Validation: the old policy fails the new guard; the corrected policy, kernel-cache guards, and full Binjovi Kustomize render pass.

The shared builder exhausted its ZFS space while 38.12GB of cache was reclaimable. Its 40GB reserve prevented sufficient cleanup. Set the main cache reserve to 8GB, the maximum to 24GB, and the free-space target to 12GB. Keep the dedicated ARM cache policy unchanged.
