 file staging assertions 或 machine text store path assertion groups 是否还能进一步局部
 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。
+
+四十九、2026-06-14 继续执行记录：browser saved file staging groups guard
+
+本轮按上一条下一步建议继续收敛 saved file staging assertions，范围仍只触及
+`wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS test glue。
+
+完成内容：
+
+- 新增 `browserInterpParameterSaveStaging` 局部常量，承载 browser-interp parameter
+  save staging filename/WASM path group；
+- 新增 `browserInterpToolTableSaveStaging` 局部常量，承载 browser-interp tool-table
+  save staging filename/WASM path group；
+- 新增 `browserRandomToolTableSaveStaging` 局部常量，承载 browser-random tool-table
+  save staging filename/WASM path group；
+- browser-interp parameter/tool-table 与 browser-random tool-table saved staging 断言
+  改为复用上述 staging groups；
+- 保持 saved file expected OPFS path、WASM path、machine id、filename 与 save options
+  不变；
+- 未改变任何 expected 字符串、输入、OPFS path、WASM path 字符串或 load/save/read
+  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 file staging
+assertions 或 remaining OPFS readback path groups 是否还能进一步局部常量化或复用
+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。
