 建议先选 `good`，因为固定 6 个 arc fixture，Node/browser coverage 已成型，适合继续
 用 single-file helper 替换 aggregate staged path guard。继续避免 blocked runtime
 promotion、browser full inventory 扩面和 JS CNC 语义实现。
+
+三十、2026-06-13 继续执行记录：good arc direct-file staging guard
+
+本批处理 `good` arc fixture loop，复用 `assertInterpRegressionFileStaging(...)`
+替换 aggregate staged path guard：
+
+- `good/good-arc.big.imperial.center-format.ngc`
+- `good/good-arc.big.metric.center-format.ngc`
+- `good/good-arc.medium.imperial.center-format.ngc`
+- `good/good-arc.medium.metric.center-format.ngc`
+- `good/good-arc.small.imperial.center-format.ngc`
+- `good/good-arc.small.metric.center-format.ngc`
+
+完成内容：
+
+- Node 侧保留 `goodArcFixtures` 与 upstream `.ngc` manifest 的覆盖检查；
+- Node 侧删除 `goodArcStagedNgcFiles` aggregate staged path 对账；
+- Node 侧在 loop 内为每个 fixture 调用 `assertInterpRegressionFileStaging(...)`；
+- browser 侧保留 fixed fixture list duplicate-free guard；
+- browser 侧删除 `goodArcStagedRelativeNgcFiles` aggregate staged path 对账；
+- browser 侧在 loop 内为每个 fixture 调用 single-file staging helper；
+- browser 侧仍不枚举目录；
+- 仅整理 host/filesystem staging guard，不改变 arc interpreter 语义或 expected output。
+
+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：
+
+继续处理 `bad` error fixture loop。它已有 Node/browser coverage 和 fixed fixture list，
+适合复用 `assertInterpRegressionFileStaging(...)` 替换当前 aggregate staged path
+guard。继续避免 blocked runtime promotion、browser full inventory 扩面和 JS CNC
+语义实现。
