//
// Parser-syntax guard for entry-point scripts shipped to end users (#542).
//
// `evolver setup-hooks --platform=codex` copies `src/adapters/scripts/*.js`
// verbatim into the user's `.codex/hooks/` directory; the CLI entry
// `index.js` is referenced by `package.json#bin`. A SyntaxError in either
// blocks the user before any code can run, with no workaround.
//
// PR #110 introduced a duplicate `const path = require('path')` in
// evolver-session-end.js, and v1.85.1 shipped that to npm — fresh
// installs hit `SyntaxError: Identifier 'path' has already been declared`
// the first time the Stop hook fired. The existing vitest suite never
// loaded those scripts (they spawn their own node process), so the
// regression made it through pre-publish. `node --check` is parse-only,
// cheap, and runs on every entry-point file unconditionally.
