 其中 `06-error-mixed-sub-styles` 有 4 个 `.ngc`，仍已在 Node/browser 分别执行；
 本批只做 direct file staged path 与 fixed manifest 对账，不扩大到 blocked
 runtime。
+
+七十五、2026-06-13 继续执行记录：m98m99 mixed direct-file staging path guard
+
+本轮继续拆 `tests/interp/m98m99`，仍保持小批量 direct file staging guard。当前
+host 仍按 blocked runtime 规则处理，不执行任何 `ENABLE_*_RUNTIME_PROBE=1`
+opt-in native probe。
+
+1. 候选选择。
+
+选择上一节建议的第二小批：
+
+- `m98m99/04-M98-but-no-sub/test.ngc`
+- `m98m99/05-M98-loops/test.ngc`
+- `m98m99/06-error-mixed-sub-styles/O...-called-with-O..._call.ngc`
+- `m98m99/06-error-mixed-sub-styles/O...-ended-with-O..._endsub.ngc`
+- `m98m99/06-error-mixed-sub-styles/O...-sub-called-with-M98.ngc`
+- `m98m99/06-error-mixed-sub-styles/O...-sub-ended-with-M99.ngc`
+
+这些 case 已在 Node/browser 单独执行，不需要 INI/HAL/task/tool DB/Python
+remap/user-M process runtime。本轮只固定 direct file staged path 与既有
+fixed `.ngc` manifest 第 4 到第 9 项的一致性，不新增 CNC 语义。
+
+2. 覆盖对账。
+
+`tests/interp/m98m99` 当前 upstream `.ngc` manifest 已由既有 fixed list 覆盖，
+本轮新增对账的 manifest slice 为：
+
+```text
+04-M98-but-no-sub/test.ngc
+05-M98-loops/test.ngc
+06-error-mixed-sub-styles/O...-called-with-O..._call.ngc
+06-error-mixed-sub-styles/O...-ended-with-O..._endsub.ngc
+06-error-mixed-sub-styles/O...-sub-called-with-M98.ngc
+06-error-mixed-sub-styles/O...-sub-ended-with-M99.ngc
+```
+
+3. 更新。
+
+更新：
+
+- `wasm-port/tests/wasm/node/verify_interp_wasm.mjs`
+- `wasm-port/tests/browser/interp_smoke.html`
+
+Node 新增：
+
+- 收集 `06-error-mixed-sub-styles` 循环中 4 个
+  `writeInterpRegressionFile(...)` 返回的 staged path；
+- 与 `04`、`05` 的 staged path 一起检查，确保实际 path 与
+  `m98m99RegressionFiles.slice(3, 9)` 推导出的 `/work/interp/m98m99/...`
+  path 一致。
+
+Browser 新增：
+
+- 收集 browser `06-error-mixed-sub-styles` 循环中 4 个 staged path；
+- 与 `04`、`05` 的 staged path 一起去掉 `/work/browser-interp/m98m99/`
+  前缀；
+- 检查结果与 `m98m99RegressionFiles.slice(3, 9)` 一致；
+- browser 仍不枚举目录。
+
+4. 已执行验证。
+
+```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_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+结果：
+
+- `git diff --check` clean。
+- `vendor sync up to date`
+- `standalone CNC semantics guard complete`
+- `interp_wasm_node_smoke=ok`
+- Node inventory 保持：
+  - `executed=28`
+  - `passed=28`
+  - `skipped=131`
+  - `unexpected_fail=0`
+- `browser_interp_smoke=ok`
+- `host_wasm_opfs_browser_smokes=ok`
+
+5. 下一步工作建议。
+
+当前工作集已稳定。建议先做小提交，message：
+
+```text
+Guard mixed m98m99 staging paths
+```
+
+提交后继续拆 `m98m99`，下一小批建议选择：
+
+```text
+07-nested-subs/test.ngc
+08-sub-follows-main/test.ngc
+09-disable-fanuc-subs/test-fanuc.ngc
+09-disable-fanuc-subs/test-rs274ngc.ngc
+```
+
+其中 `09-disable-fanuc-subs` 用 `writeInterpRegressionFiles(...)` staging 同一目录
+下两个 `.ngc` 和两个 `.ini`。本批仍只做 staged path 与 fixed manifest 对账，
+不扩大到 blocked runtime。
