…gent-substrate#2618) - Follow-up to agent-substrate#2531: --upstream-connect now defaults to true, so the Envoy router reaches atunnel through mTLS CONNECT tunnels on 8443. --upstream-connect=false goes back to HTTPS on 443. - An empty --upstream-credential-bundle now needs --upstream-connect=false, and the startup error says so. The check only applies to the Envoy ingress router; the egress gateway and agentgateway don't use the flag (agentgateway always uses CONNECT). - Split xDS server setup out of startEnvoyDataplane so a new test can parse real flags and check the built snapshot for both settings. - The e2e gRPC downgrade test now expects only gRPC Unavailable, so it fails if the router falls back to the HTTPS path. - Updated architecture.md, threat-model.md and the router manifest comment. Related: agent-substrate#1208 > It's a good idea to open an issue first for discussion. - [x] Tests pass - [x] Appropriate changes to documentation are included in the PR
