   - Worker D `/mnt/Data1T/mnote-worktrees/0525-ae-worker-d-regression-smoke`，run `reasonix-2026-05-24T23-18-29-435Z-3225d16e` 串线执行成 5-29 overlay 只读审计，未运行 `task489` / `task488` / `task487` / `task451` smoke；本轮 3-20 smoke 输出拒收。
   - 后续 3-20 推荐下一刀：只读审计 `syncSidebarFileTreeSelection` 是否可迁入 `filetree-runtime.js`，或在明确降级兼容策略后评估 inline fallback 瘦身；不要继续盲迁 `refreshLocalFolderSidebarSnapshot` 整体。
+- 2026-05-25：发现未授权 Reasonix runner / ACP 进程指向 `/mnt/Data1T/mnote-worktrees/0525-af-worker-b-3-20-filetree-selection-helper`。
+  - 处置：该 worker 未由主控按当前 goal 派发，已终止相关 `reasonix-coding-runner` / `reasonix acp` 进程；主控复查后未发现残留 Reasonix worker。
+  - 采纳：不读取、不采纳该 worktree 的任何输出；后续若要审计 `syncSidebarFileTreeSelection`，必须重新按最多 2 worker 的短批次显式派发。
