// Regression guards for Windows `hermes` resolution in main.cjs.
|
|
//
|
|
// main.cjs has no module.exports, so these follow the repo's source-assertion
|
|
// test pattern (see windows-child-process.test.cjs). They pin the two Windows
|
|
// resolution bugs that caused desktop reinstall loops:
|
|
// 1. findOnPath() tried the empty extension FIRST, so an extensionless
|
|
// Git-Bash `hermes` shim shadowed the real hermes.cmd/hermes.exe; the
|
|
// shim then failed the --version probe and the desktop fell through to a
|
|
// spurious bootstrap/repair.
|
|
// 2. handOffWindowsBootstrapRecovery() chose --update vs the destructive
|
|
// --repair by checking ONLY venv\Scripts\hermes.exe (the console-script
|
|
// shim, written at the END of venv setup and absent in interrupted
|
|
// states), so it escalated to a full venv recreate even on healthy
|
|
// installs.
