Why: the dual-speed slow lane shipped as an observable capability plus soft prompt guidance, but on the real (non-mock) path models routinely grind through heavy document tasks synchronously for minutes with zero user-visible output - the pattern only engages when the model happens to think of it. Evidence: five new unit tests over an injected clock cover fire-after-threshold, quiet-before-threshold, disabled-by-setting, and the replied/delegated guard paths (reminders observed in the captured kernel requests); full go test ./... 32 pkgs green. Real-model run recorded in the Dev task card. Impact: runDirect tracks run start, user-reply, and background-delegation state; reminders() injects a one-shot dual-speed nudge (SR-B10) once elapsed time crosses runtime.dualSpeedNudgeSeconds (default 75s, 0 disables) while the user has neither a reply nor a background lane. New setting registered. Refs: Dev task feature/dual-speed-real-path; SR-B10 (RDM requirements/01 V2.1).
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。
