- df-ai: context 历史中毒三档自愈 sanitize_messages(AC3)+anthropic_compat tool_use_id None 跳过(AC1/AC2)+删 router/stream 死码
- df-core: events 加 select_type+decisions 多选审批契约(F-260615-01)
- df-execute: shell run_command 工具复用(F-260615-05)
- df-nodes: human_node 多选校验+2 端到端测(F-01)+取消跳 set_failed(B-03b-R1/R2/R8)
- df-workflow: executor/dag/state cancel 闭环(B-06/07/03a/b)+provider approve options(R-PD-5)
- df-storage: find_path_conflict 抽公共(R-PD-11)+COLS 常量断言
- df-ideas: 删 IdeaPromoter/PromotionPolicy 死码(R-PD-14)
- src-tauri/commands/ai: secret keyring 迁移(FR-S1/R-PD-4)+GeneratingGuard RAII+disarm(B-09/26)+newConversation 软复位(B-10)+stream 心跳/stop select/空回复判错(B-02/04/05/15)+run_command(F-05)+mask audit(AR-3)
- src-tauri/commands/{project,task,workflow,mod,lib,state}: task detail IPC(F-02)+approve decisions+task list 联动(B-29)
- Cargo.lock+Cargo.toml 依赖同步

 //! 想法晋升 — 将想法转为项目
+//!
+//! 历史的 IdeaPromoter/PromotionPolicy/try_promote/do_promote 三件套
+//! 是空壳 TODO（do_promote 从未接入 df-project，误接入会得虚假成功），
+//! 实际晋升路径由 src-tauri/src/commands/idea.rs::promote_idea 直接复用
+//! df-project::ProjectManager::create_from_idea 完成。这里仅保留作为
+//! IPC 返回类型的 PromotionResult。
+//!
+//! 死代码已清，详见 docs/todo.md R-PD-14。
