 saved parameter value object、save result expected lines、saved/readback expected
 lines 是否能对齐为 locals 或复用现有 `opfsParameter*` helpers；只改测试胶水，不改变
 参数值、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 OPFS direct session parameter value locals guard
+
+本轮按上一条下一步建议继续收敛 direct `browser-interp` session 的 saved parameter
+value groups，范围仍只触及 `wasm-port/tests/browser/interp_smoke.html` 的
+browser/OPFS test glue。
+
+完成内容：
+
+- 为 direct `browser-interp` session 增加 `browserInterpParameterValues`、
+  `browserInterpParameterExpectedValues`、`browserInterpParameterReadbackValues`
+  局部常量；
+- saved parameter value object 改为复用既有 `opfsParameterValues(...)`；
+- save result expected lines 改为复用既有 `opfsParameterResultLines(...)`；
+- saved parameter machine-file readback expected lines 改为复用既有
+  `opfsParameterTextLines(...)`，并继续显式保留 `absent=<_named_param>`；
+- 数字保存值与字符串 expected/readback 值仍分开显式声明，未新增格式转换逻辑；
+- `5220` 仍由 `opfsParameterValues(...)` 固定为 `1.0`，实际保存参数值不变；
+- 未改变参数值、OPFS path、WASM path 字符串、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

+
+关键输出：

+
+下一步建议：
+
+继续小批量 browser OPFS test glue guard。优先扫描 direct `browser-interp` session 的
+initial parameter load result 与 backup readback expected lines 是否能复用
+`browserDirectParameterSeedLines(...)` 或现有 `opfsParameter*` helpers；只改测试胶水，
+不改变参数值、OPFS path、WASM path 字符串或保存/读取行为。
