The koffi IFileOpenDialog conversation runs in a spawned child process instead of a worker thread: the dialog is the child's first window, so Windows activates it without a foreground call, and a native fault stays contained to the child. The driver maps the child's message protocol onto a promise and services aborts by posting WM_CLOSE to the dialog thread's windows, killing the child when the close budget is exhausted. The built worker ships as lib/worker.cjs (the ./worker export) under plain node, and win32-dialog.spec.ts returns to the thread-safe pool.

/**
|
|
* Keyless built-artifact guard (the `dsh-workflow-workerthread` built-worker
|
|
* shape): plain `node` runs `lib/worker.cjs` and the bundle reaches its
|
|
* real koffi requires. POSIX hosts prove the load path end to end through
|
|
* the deterministic ole32 rejection; win32 skips (a real dialog would
|
|
* open), where the win32-only smoke in win32-dialog.spec.ts covers the
|
|
* source plane instead. Skips until a build produces the artifact.
