 `assertRemapRegressionStaging(...)` 拆成 coverage helper 与 per-file staging helper。
 `nested-remaps-oword` 含 expected-unstaged 文件，应留到后续单独处理。继续避免
 blocked runtime promotion、browser full inventory 扩面和 JS CNC 语义实现。
+
+四十五、2026-06-13 继续执行记录：initial remap per-file staging helper guard
+
+本批开始处理 remap 专用 staged path helper，并只选择没有 expected-unstaged 额外清单的
+短小 fixture：
+
+- `duplicate-o-word`
+- `fail/args.0`
+- `fail/args.1`
+
+完成内容：
+
+- Node 侧新增 `assertRemapRegressionCoverage(...)`，保留 vendored `.ini/.ngc`
+  manifest coverage 与 expected-unstaged overlap 检查；
+- Node 侧新增 `assertRemapRegressionFilesStaging(...)`，逐个文件检查
+  `/work/remap/<name>/<file>` staged path；
+- Node 侧保留原 `assertRemapRegressionStaging(...)` 给尚未拆分的 remap fixture 使用；
+- Node 侧将上述 3 个 remap fixture 切换为 coverage helper 加 per-file staging helper；
+- browser 侧新增同名 per-file staging helper，逐个文件检查
+  `/work/browser-remap/<name>/<file>` staged path；
+- browser 侧同步替换上述 3 个 remap fixture；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 remap、O-word、argument validation、
+  expected-error 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：
+
+继续处理没有 expected-unstaged 额外清单的 remap fixture。优先候选：
+
+- `fail/args.2`
+- `fail/body-ngc`
+- `m30-interaction`
+
+这三组 file list 均为 `test.ini`、`test.ngc`、`rm400.ngc`，适合继续切换到
+`assertRemapRegressionCoverage(...)` 加 `assertRemapRegressionFilesStaging(...)`。
+仍暂缓 `nested-remaps-oword`，因为它含 expected-unstaged 文件，需要单独保留
+staged/unstaged overlap guard。继续避免 blocked runtime promotion、browser full
+inventory 扩面和 JS CNC 语义实现。
