+## ACP Forwarding Topology
+
+This repository exposes one bridge entrypoint and forwards to four verified public targets. The full Mermaid diagram lives in [docs/architecture/acp-forwarding-topology.md](/Users/shenlan/workspaces/cloud-neutral-toolkit/xworkmate-bridge/docs/architecture/acp-forwarding-topology.md).

+notes:
+  - The bridge reads its own auth token from ACP_AUTH_TOKEN.
+  - The provider catalog is normally synced through xworkmate.providers.sync.
+  - session.message should resend routing on follow-up turns for codex and opencode.
