 当前 Node 侧已有 fixed path manifest 对账，browser 侧仍有本地数组 staged path 对账；
 可小批量抽成 single-file 或 fixed-list helper，继续检查 staged path 与 manifest 一致。
 继续避免 blocked runtime promotion、browser full inventory 扩面和 JS CNC 语义实现。

+四十、2026-06-13 继续执行记录：magic comments single-file staging guard
+
+本批继续收敛最后可见的 fixed `.ngc` staged path 对账：
+
+- `magic_comments/param_format_printing/test.ngc`
+
+完成内容：
+
+- Node 侧将 `magic_comments` 的 inline staged path `deepEqual` 替换为
+  `assertInterpRegressionFileStaging(...)`；
+- browser 侧移除本地 `magicCommentsStagedNgcFiles` 数组与 `replace(...)` 对账，
+  改为同一个 single-file staging helper；
+- Node/browser 侧保留 fixed `.ngc` manifest coverage 和 browser duplicate-free guard；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 magic comment、parameter formatting 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：
+
+先做 remaining staging guard inventory，确认是否还存在非 helper 的 inline staged path
+对账。当前可见的 `replace(...)` staged path 检查主要集中在通用 helper 内部；
+如果继续做小步代码收敛，优先候选是固定 manifest 且已有 Node/browser coverage 的
+目录级 helper case，例如：
+
+- `m98m99/06-error-mixed-sub-styles`
+- `m98m99/09-disable-fanuc-subs`
+- `m98m99/11-main-program-oword`
+
+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。
