 - Release/Windows: run release-check npm pack/install/root probes through the shared npm runner so native Windows avoids bare `npm` lookup and `.cmd` shell-argv handling.
 - Release/Windows: run cross-OS release check `.cmd` shims through explicit `cmd.exe` wrapping so native Windows install and gateway probes avoid Node shell-argv handling.
 - Control UI/Windows: run i18n Pi, npm, and pnpm helper commands through explicit Windows runners so native Windows translation sync avoids brittle `.cmd` launches.
+- Scripts/Windows: run the Z.AI fallback repro through the shared pnpm runner so native Windows avoids raw `.cmd` launches.
 - Plugins/Windows: run plugin npm package staging through the shared npm runner so native Windows release checks avoid bare `npm` lookup and `.cmd` shell-argv handling.
 - Checks/Windows: route full `pnpm check` stage commands through the managed child runner so Windows avoids Node shell-argv deprecation warnings there too.
 - Agents/fs: allow workspace-only host write/edit tools to write through in-workspace symlink directory parents while preserving outside-workspace symlink rejection. Fixes #84696. Thanks @garbagenetwork.
