Why: a non-nil Authenticator with Enabled=false is the embedded no-auth
mode; reporting auth=true there made the sidebar account footer show
the wrong identity state (found in the live headless walk).
Evidence: restarted binary now returns {"auth":false,...} in embedded
mode; TestTaskListAndFlags still green.
Impact: response field value only.
Agent-System-Backend
对话系统后端：Go 模块化单体，默认构建为单二进制（go:embed 内嵌前端与嵌入式 SQLite 存储）。组合 Agent-Native / Agent-Squad / Agent-Intent 生态，依赖 agent-system-core 契约。
契约与架构见 Agent-System-Documents 设计方案与架构文档；开发规范见 development-guidelines（Dev 仓 development/guidelines）。本仓为 Agent-System 多仓组合的组成部分。
