+十二、2026-06-13 继续执行记录：fixture loop staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第七轮，处理 Node/browser 成对覆盖的 fixture loop
+staging 写入点：
+
+```text
+INTERP_ERROR_FIXTURES
+INTERP_FILE_FIXTURES
+INTERP_BROWSER_FILE_FIXTURES
+```
+
+2. 已完成改动。
+
+- Node 侧新增 `writeLocalErrorGcodeFixture(...)`；
+- browser 侧新增 `writeLocalErrorGcodeFixture(...)`；
+- `INTERP_ERROR_FIXTURES` 的 file-error loop 两侧均改为 helper 写入；
+- `INTERP_FILE_FIXTURES` / `INTERP_BROWSER_FILE_FIXTURES` 的 file loop 两侧均改为
+  `writeLocalGcodeFixture(...)` 写入；
+- helper 显式检查 staged `wasmPath` 与期望路径一致；
+- browser 侧仍不枚举目录；
+- 未修改 G-code 内容、canon expected、error expected 或 interpreter 语义。
+
+涉及文件：
+
+```text
+wasm-port/tests/wasm/node/verify_interp_wasm.mjs
+wasm-port/tests/browser/interp_smoke.html
+```
+
+3. 已完成的目标验证。
+
+```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
+```
+
+4. 本批剩余建议验证。
+
+```bash
+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
+```
+
+如果通过，提交建议：
+
+```text
+Guard fixture loop staging
+```
+
+5. 下一步工作建议。
+
+继续 staged path guard inventory 第八轮，优先处理 `namedparam_semantics` /
+`namedparam_ini_semantics` 等 INI-context 单文件 direct `/work/...` 写入点，或
+`ini_tool_table` 固定三文件 staging manifest；继续避开 parameter/tool table runtime
+state tests 和 blocked runtime promotion。
+
+下一轮第一条命令仍保持：

+```bash
+git status --short && git log -5 --oneline && tail -n 120 text7.txt && awk '/^[一二三四五六七八九十百]+、/ {print}' text7.txt | sort | uniq -d
