OmniRoute/tests/unit/auggie-win32-spawn-6304.test.ts

/**
 * Regression test for #6304 — Auggie (Augment CLI) provider always fails on
 * Windows with `spawn EINVAL`.
 *
 * Root cause: resolveAuggieBin() falls back to "auggie.cmd" (the global-npm
 * bin shim) on win32. Since Node's CVE-2024-27980 fix (Node >=18.20.2/
 * 20.12.2/21.7.3), `spawn()` refuses `.cmd`/`.bat` targets without
 * `shell: true`, throwing `spawn EINVAL`.
 *
 * Both auggie spawn sites build their options via the shared
 * buildAuggieSpawnOptions() helper, so asserting on that helper's output
 * covers spawnAuggie() (non-streaming path) and the inline spawn in
 * runStreaming() alike.
