+十七、2026-06-13 继续执行记录：user-M helper staging manifest guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第十二轮，处理 Node 侧 generated user-M helper
+staging：
+
+```text
+writeUserMCodeFixture(...)
+```
+
+2. 已完成改动。
+
+- Node 侧新增 `assertUserMCodeFixtureStaging(...)`；
+- generated user-M fixture 增加 fixed manifest、duplicate-free 和 root/path parity
+  guard：
+  - `test.ini`
+  - `test.ngc`
+  - `M110` / `M111`
+- `writeUserMCodeFixture(...)` 写入前先校验 staging root 与 manifest；
+- 未修改 generated INI、G-code、M-code 内容、expected output 或 interpreter 语义；
+- 未提升 `L4-USER-M-PROCESS`，也未改变 blocked runtime promotion 状态。
+
+涉及文件：
+
+```text
+wasm-port/tests/wasm/node/verify_interp_wasm.mjs
+```
+
+3. 已完成的目标验证。
+
+```bash
+git diff --check
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_interp_wasm.sh
+```
+
+4. 本批剩余建议验证。
+
+```bash
+wasm-port/tools/verify_vendor_sync.sh
+wasm-port/tools/verify_no_standalone_cnc_semantics.sh
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+如果通过，提交建议：
+
+```text
+Guard user-M helper staging
+```
+
+5. 下一步工作建议。
+
+继续 staged path guard inventory 第十三轮，优先扫描剩余 generated/direct staging
+点；较安全候选是 restore-parameter negative fixtures 的 path guard，但仍需明确只做
+filesystem staging guard，不改变 parameter runtime semantics。
+
+下一轮第一条命令仍保持：
+
+```bash
+git status --short && git log -5 --oneline && tail -n 120 text7.txt && awk '/^[一二三四五六七八九十百]+、/ {print}' text7.txt | sort | uniq -d
+```
