+"""API key control-plane default-deny tests (Stage 1 收口).
+
+service principal (API key) 只能访问数据平面 (threads/runs/assistants);
+控制平面 (models/mcp/memory/skills/channels/agents 与管理/auth) 一律 403。
+真人 cookie 路径不受影响。设计见 spec
+docs/superpowers/specs/2026-06-28-api-key-control-plane-default-deny-design.md。
