 readback 与 backup readback expected text 是否还能用只读 expected-lines helper 收敛；

+二十三、2026-06-14 继续执行记录：browser OPFS custom session parameter text helper guard
+
+本轮按上一条下一步建议继续收敛 custom session saved parameter readback 与 backup
+readback expected text，范围仍只触及 `wasm-port/tests/browser/interp_smoke.html` 的
+browser/OPFS test glue。
+
+完成内容：
+
+- 新增 `opfsParameterTextLines(...)`，统一 custom session saved parameter text 中
+  5161、5162、5221、5399 的 expected lines；
+- INI-named session 的 saved parameter readback 与 backup readback 均复用
+  `opfsParameterTextLines(...)`；
+- explicit session 的 saved parameter readback 与 backup readback 均复用
+  `opfsParameterTextLines(...)`；
+- tab 分隔的 saved parameter text 与 space 分隔的 backup text 仍在调用处显式区分；
+- 所有 readback 仍通过 `verifyExpectedOutput(...)` 做精确文本校验；
+- custom parameter/tool-table filename 输入、OPFS path、WASM path 字符串与
+  save/read 行为均未改变；
+- 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
+```
+
+下一步建议：
+
+继续小批量 browser OPFS test glue guard。优先扫描 custom session tool-table saved
+text expected lines 是否还能用只读 expected-lines helper 收敛；只改测试胶水，保持
+精确文本校验，不改变 custom filename 输入、OPFS path、WASM path 字符串或保存/读取行为。
