+# scripts/archive — 已结案的一次性脚本
+
+结论已固化进代码 / DESIGN / PROGRESS 的一次性诊断与 backfill,归档留证不再维护:
+
+- `diag_task_*` / `diag_narrated_*` / `diag_progress_*` / `diag_sched_*`:带具体
+  task-id 的事故取证(对应结论见 PROGRESS / git log / 记忆条目)
+- `diag_run_python_*` / `diag_glm_empty_probe` / `diag_mmdc_*` / `diag_malformed_samples`
+  / `diag_svgguard_breakdown` / `diag_search_args` / `diag_error_retry` / `diag_tool_repeat`:
+  已结案调查(RepeatGuard / salvage / GLM 禁 thinking / mermaid loopback 等均已上线)
+- `backfill_*`:对应 migration 应用完即废
+
+可复用的运维/诊断工具(toolfail_scan / unifyllm / asr / wechat 推送 / context
+压力 / dump_task 等)仍在 `scripts/` 一级;DESIGN 引用的协议探针
+(`probe_clawbot*` / `probe_ark_doc`)也留在一级。
