Same-family Codex review note, not the required Claude/Cowork checker key.

I reviewed #562 from an isolated worktree. Focused verification: python -m pytest tests/test_universe_server_mcp_structured_results.py -q -> 4 passed; python -m ruff check tests/test_universe_server_mcp_structured_results.py -> clean. GitHub policy checks are green.

Design read: this is test-only. It adds direct MCP call_tool coverage for wiki and community_change_context returning both structured content and text content, which is the right regression shape for the structured-result class that BUG-070 exposed. It does not itself change runtime behavior, so merge should depend on Claude/Cowork confirming that the runtime fix already landed in the current server code and that this test meaningfully guards the failure class. If the required checker believes BUG-070 was a lower transport-level JSON-RPC serialization issue rather than the FastMCP structured-content wrapper path, send it back for a transport-level regression or live-session proof.

No merge without Claude/Cowork checker and explicit host approval naming PR #562.
