 继续小批量 browser test glue guard。优先扫描 ini-named/explicit session saved parameter
 expected line groups 是否也能复用 shared helpers；只改测试胶水，不改变输入、OPFS path、
 WASM path 字符串或保存/读取行为。
+
+三十八、2026-06-14 继续执行记录：browser custom session plain parameter expected lines guard
+
+本轮按上一条下一步建议继续收敛 ini-named/explicit session saved parameter expected line
+groups，范围仍只触及 `wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS test glue。
+
+完成内容：
+
+- 新增 `opfsSavedParameterPlainTextLinesForValues(...)` helper，统一生成不带 named-param
+  附加行的 saved parameter expected lines；
+- ini-named session 的 saved parameter text 与 backup readback expected lines 改为复用
+  `opfsSavedParameterPlainTextLinesForValues(...)`；
+- explicit session 的 saved parameter text 与 backup readback expected lines 改为复用
+  `opfsSavedParameterPlainTextLinesForValues(...)`；
+- 保持 ini-named/explicit session 的 saved parameter/readback expected 文本、OPFS path 与
+  WASM path 不变；
+- 未改变任何 expected 字符串、输入、OPFS path、WASM path 字符串或 save/read/load
+  行为；
+- 未改变 staging path 模型、OPFS bridge behavior、file-service、SDK planner、
+  interpreter、INI、tool、parameter 或 LinuxCNC-owned runtime semantics。
+
+验证已通过：
+
+```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_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+关键输出：
+
+```text
+vendor sync up to date
+standalone CNC semantics guard complete
+interp_wasm_node_smoke=ok
+sim_configs_wasm_node_inventory_executed=28
+sim_configs_wasm_node_inventory_passed=28
+sim_configs_wasm_node_inventory_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+browser_interp_smoke=ok
+host_wasm_opfs_browser_smokes=ok
+```
+
+下一步建议：
+
+继续小批量 browser test glue guard。优先扫描 custom session saved tool-table expected line
+groups 是否也能局部常量化或复用 existing helpers；只改测试胶水，不改变输入、OPFS
+path、WASM path 字符串或保存/读取行为。
