ConfigSource:Mode = Direct (default, read central SQL) | FetchAndCache (fetch the artifact from central over gRPC, read LocalDb). The validator fails host start on a FetchAndCache shape that cannot fetch — no endpoints, a non-http(s) endpoint, no shared key, or a non-positive timeout — because each otherwise surfaces as a silent absence (a deploy that never applies). ConfigServe (the central serve surface) takes a plain Configure: a 0 port is a valid "disabled". Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
