 - `trade-api` and `trade-frontend` use the current live images from Gitea registry and the same bootstrap wrapper/config pattern as the source environment.
 - `dlob-publisher-hot` now targets the host validator on `sol` through `trade-infra` services and writes `dlob-hot:*` into the shared Redis host service.
 - `dlob-publisher-all` now targets the same host validator path on `sol` and writes `dlob-all:*` into the shared Redis host service.
+- `dlob-publisher-hot` and `dlob-publisher-all` use `/startup` for Kubernetes liveness on `sol`; the internal `/health` endpoint stayed noisy on self-hosted Agave while downstream `drift_ticks` data remained fresh, so the operator smoke check is the stronger health gate for canary rollouts.
