Every chart was installed twice in a throwaway k3d cluster (origin/main vs this branch) with real Postgres/Redis/dex instances and observed for readiness ordering, stability and dependency-outage behavior. Findings: - voucher-vault: Django only accepts Hosts 127.0.0.1 and the configured DOMAIN; the default probe Host (pod IP) always got 400. Probes now send 'Host: 127.0.0.1'. - zipline: /api/healthcheck includes the database, so liveness now uses '/' (readiness/startup keep /api/healthcheck). Verified live: on a Postgres outage the pod turns NotReady within 30s and is never restarted by the kubelet. - outline: '/' also returns 500 when the database is down, so there is no dependency-free endpoint; all three probes use /_health.
