+-- Add DeepSeek Harness (dsh-catl-plugins) as a builtin ACP agent.
+--
+-- Local CLI entry: node + absolute path to dsh-catl-plugins/scripts/run.mjs
+-- Out-of-tree ACP bridge (streaming + usage_update + egress guard + Team MCP).
+-- Requires DEEPSEEK_API_KEY in the process env (or agent_metadata.env) — never
+-- commit secrets.
+--
+-- command/args use a portable placeholder; operators MUST set args to the
+-- absolute path of scripts/run.mjs on this host (AionUi Agent settings), and
+-- set DSH_ROOT / DEEPSEEK_API_KEY in agent_metadata.env.
+--
+-- Post-030 seed shape: builtin rows use agent_id = id and user_id NULL.
