 下一批可以决定是否继续把这些目录级 aggregate guard 拆成更细的 per-file staging
 helper，或仅提交一次 inventory 说明。继续避免 blocked runtime promotion、browser
 full inventory 扩面和 JS CNC 语义实现。
+
+四十一、2026-06-13 继续执行记录：m98m99 per-file staging helper guard
+
+本批继续按第 40 批建议处理固定 manifest 且已有 Node/browser coverage 的目录级
+aggregate guard：
+
+- `m98m99/06-error-mixed-sub-styles`
+- `m98m99/09-disable-fanuc-subs`
+- `m98m99/11-main-program-oword`
+
+完成内容：
+
+- Node 侧新增 `assertInterpRegressionFilesCoverage(...)`，把 vendored
+  `.ini/.ngc/.tbl` manifest coverage 与 staged path 对账分离；
+- Node 侧新增 `assertInterpRegressionFilesStaging(...)`，逐个文件复用
+  `assertInterpRegressionFileStaging(...)` 检查 staged path；
+- Node 侧将上述 3 个 `m98m99` 目录从 aggregate staged path 对账切换为
+  coverage helper 加 per-file staging helper；
+- browser 侧新增同名 per-file staging helper，保留 fixed manifest duplicate-free
+  guard；
+- browser 侧同步将上述 3 个目录从 `assertInterpRegressionStaging(...)` 切换到
+  per-file helper；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 Fanuc/Rs274NGC subroutine、
+  INI context、main-program oword 或 interpreter 语义。
+
+已运行验证：
+
+```bash
+git diff --check
+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_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
+```
+
+结果：全部通过。
+
+下一步建议：
+
+继续收敛剩余 directory aggregate staging guard。当前可见候选：
+
+- `do-while-break`
+- `cam-nisley`
+- `g76`
+- `m98m99/13-named-program`
+
+建议下一批优先处理 `m98m99/13-named-program`，它只有 2 个 `.ngc` 文件，已经有
+fixed manifest 和 Node/browser coverage，适合直接切换到 per-file helper。其后再按
+小批量处理 `do-while-break`、`cam-nisley`、`g76`。继续避免 blocked runtime promotion、
+browser full inventory 扩面和 JS CNC 语义实现。
