Guard interp regression staging helper

 fixture；若没有合适小批次，转向补齐 staging guard 的文档索引或生成一个
 machine-readable fixture coverage manifest。继续避免 blocked runtime promotion、
 browser full inventory 扩面和 JS CNC 语义实现。
+
+二十二、2026-06-13 继续执行记录：interp fixture staging helper guard
+
+本批回到 `writeInterpRegressionFiles(...)` helper，先整理已有 Node/browser coverage
+里的两个固定 `.ngc/.tbl` fixture：
+
+- `interp/cam-nisley`
+- `interp/g76`
+
+完成内容：
+
+- Node 侧新增 `assertInterpRegressionStaging(...)`；
+- Node 侧对 upstream vendored `.ini/.ngc/.tbl` 文件清单与 fixed manifest 精确对账；
+- Node 侧检查 staged path 与 `/work/interp/<name>/...` fixed manifest 一致；
+- browser 侧新增同名 `assertInterpRegressionStaging(...)`；
+- browser 侧检查 fixed manifest duplicate-free，并检查 staged path 去掉
+  `/work/browser-interp/<name>/` 前缀后与 fixed manifest 一致；
+- `cam-nisley` 与 `g76` 改用该 helper，去掉内联重复 guard；
+- 仅整理 host/filesystem staging guard，不改变 G-code、tool table 或 threading 语义。
+
+已运行验证：
+
+```bash
+git diff --check
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_interp_wasm.sh
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+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_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+结果：全部通过。
+
+下一步建议：
+
+继续复用 `assertInterpRegressionStaging(...)` 处理已有 `writeInterpRegressionFiles(...)`
+调用里的小批次。优先候选：
+
+- `m98m99/09-disable-fanuc-subs`
+- `m98m99/11-main-program-oword`
+
+这两个已有固定 file list 和 Node/browser coverage，适合把现有 m98m99 aggregate
+slice guard 拆出更直接的 per-directory staged path guard。仍不推进 blocked runtime
+promotion、browser full inventory 扩面或 JS CNC 语义实现。
