 value groups，把 `explicit*Parameter*` 数组也收敛到
 `opfsParameterValueSet(...)` object adapter；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。
+
+二十、2026-06-14 继续执行记录：browser explicit parameter object adapter guard
+
+本轮按上一条下一步建议继续收敛 explicit custom session parameter result/text helper
+调用点的参数展开，范围仍只触及
+`wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS test glue。
+
+完成内容：
+
+- `explicitInitialParameterValues` 改为 `opfsParameterValueSet(...)`；
+- `explicitParameterValues`、`explicitParameterExpectedValues` 与
+  `explicitParameterReadbackValues` 改为 `opfsParameterValueSet(...)`；
+- explicit custom session parameter restore/save/readback/backup 调用点改为复用
+  `opfsParameterResultLinesForValues(...)`、
+  `opfsParameterTextLinesForValues(...)` 与
+  `opfsParameterValuesForValueSet(...)`；
+- seed file 写入仍显式展开 `parameter5161/5162/5221/5399` 字段，不推导
+  LinuxCNC-owned parameter 文件格式；
+- 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
+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_interp_wasm.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+关键输出：
+
+```text
+browser_interp_smoke=ok
+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_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+host_wasm_opfs_browser_smokes=ok
+```
+
+备注：
+
+- 当前 sandbox 会拦截本地 HTTP server socket bind；browser smoke 与
+  `verify_host_smokes.sh` 的 browser 阶段需授权运行；
+- 本轮 browser smoke 与 host smoke 均已授权运行并通过。
+
+下一步建议：
+
+继续小批量 browser test glue guard。优先扫描是否值得新增
+`opfsParameterSeedTextForValues(...)` object adapter，收敛 direct、INI-named 与
+explicit parameter seed file 写入的字段展开；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。
