   staged path guard，建议留到最后单独处理。
 
 继续避免 blocked runtime promotion、browser full inventory 扩面和 JS CNC 语义实现。
+
+四十八、2026-06-13 继续执行记录：final special remap per-file staging helper guard
+
+本批处理剩余两个特殊 remap staged path guard：
+
+- `nested-remaps-oword`
+- `remap-io`
+
+完成内容：
+
+- Node 侧将 `nested-remaps-oword` 从 `assertRemapRegressionStaging(...)` 切换为
+  `assertRemapRegressionCoverage(...)` 加
+  `assertRemapRegressionFilesStaging(...)`；
+- Node 侧继续保留 expected-unstaged `testsub.ngc` 的 manifest coverage 与 overlap
+  guard；
+- browser 侧新增 `assertRemapRegressionUnstagedOverlap(...)`，只检查 fixed list 与
+  expected-unstaged list 不重叠，不枚举目录；
+- browser 侧将 `nested-remaps-oword` 切换为 expected-unstaged overlap guard 加
+  per-file staging helper；
+- Node/browser 侧将 `remap-io` vendored file list 切换为 per-file staging helper；
+- `remap-io` 运行时生成的 `simpockets.tbl` 继续保留单独 staged path guard；
+- 删除 Node/browser 侧已无调用的 `assertRemapRegressionStaging(...)` aggregate helper；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 remap execution、nested O-word、
+  remap I/O、generated tool table 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：
+
+remap/ccomp/g10/ordinary interp aggregate staged path guard 已收敛完成。下一批建议做一次
+remaining staged path guard inventory，重点确认：
+
+- 是否还有 `replace(.../work/browser-...)` 形式的 inline staged path 对账可以改为
+  专用 helper；
+- 是否还有 generated-file staged path guard 需要单独命名，例如 `simpockets.tbl`；
+- 是否有 helper 已无调用，可以删除；
+- 不推进 blocked runtime promotion，不扩大 browser full inventory，不新增 JS CNC 语义。
