+十、2026-06-13 继续执行记录：browser nc-files staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第五轮，处理 browser 侧 vendor `nc_files` helper：
+
+```text
+runVendorNcFile(...)
+runVendorNcFileWithToolTable(...)
+```
+
+2. 已完成改动。
+
+- browser 侧新增 `assertVendorNcFileStaging(...)`；
+- browser 侧新增 `assertVendorNcFileContextStaging(...)`；
+- direct `nc_files` helper 增加 `/work/browser-nc-files/<file>` root parity guard；
+- context helper 增加固定 manifest guard：
+  - `<file>`
+  - `tool.tbl`
+  - `nc_files_context.ini`
+- context helper 增加 staged root/path parity guard；
+- browser 侧仍不枚举目录；
+- 未修改 vendor `nc_files`、tool table 内容、INI 内容或 interpreter 语义。
+
+涉及文件：
+
+```text
+wasm-port/tests/browser/interp_smoke.html
+```
+
+3. 已完成的目标验证。
+
+```bash
+git diff --check
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.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_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_interp_wasm.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 browser nc-files staging
+```
+
+5. 下一步工作建议。
+
+继续 staged path guard inventory 第六轮，优先处理 browser/Node 中剩余的单文件
+direct `/work/...` 写入点，例如 `disable_fanuc_style_sub_m98.ngc` 或 spindle-orient
+INI fixture staging；继续避开 parameter/tool table runtime state tests 和 blocked
+runtime promotion。
+
+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
+```
