 `assertInterpRegressionFileStaging(...)` 或小型 per-directory helper 替换内联 staged
 path 对账。继续避免 blocked runtime promotion、browser full inventory 扩面和 JS CNC
 语义实现。
+
+三十四、2026-06-13 继续执行记录：early direct-file staging guard
+
+本批继续收敛 earlier direct-file guard，处理 5 个已有 Node/browser coverage 的 fixture：
+
+- `do-while-break/bug.ngc`
+- `do-while-break/test.ngc`
+- `oword-bug315/test.ngc`
+- `oword-bug315-p2/test.ngc`
+- `exists/test.ngc`
+- `return-value/test.ngc`
+
+完成内容：
+
+- Node 侧将 `do-while-break` 改为 `writeInterpRegressionFiles(...)` 加
+  `assertInterpRegressionStaging(...)`，对该目录 2 个 `.ngc` fixture 精确对账；
+- Node 侧将 `oword-bug315`、`oword-bug315-p2`、`exists`、`return-value` 的内联
+  staged path 对账替换为 `assertInterpRegressionFileStaging(...)`；
+- browser 侧同步将 `do-while-break` 改为 fixed manifest 加 directory staging guard；
+- browser 侧同步将其余 4 个单文件 fixture 改为 single-file staging helper；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 O-word control-flow、exists 或 return
+  value 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：
+
+继续收敛后续 earlier direct-file guard。优先候选：
+
+- `subs-follow-main`
+- `fractional-linenumbers`
+- `crazy-paths`
+- `namedparam-bug424`
+- `flowsnake`
+
+这些已有 Node/browser coverage 和 fixed `.ngc` manifest，可继续用
+`assertInterpRegressionFileStaging(...)` 替换内联 staged path 对账。继续避免 blocked
+runtime promotion、browser full inventory 扩面和 JS CNC 语义实现。
