// Prove two things about the target image's server directory, in order:
//
// 1. The production `CMD` can still find its ECMAScript module loader,
//    `server/node_modules/tsx/dist/loader.mjs`. That path is a symbolic
//    link into the workspace pnpm store, and the `cloud` stage's Sentry
//    copy writes into the same `server/node_modules` directory. A copy
//    that removes or shadows the link stops the container from booting.
// 2. The installed `@sentry/node` package resolves, the same way the
//    server's own peer-version gate does
//    (server/src/peer-version-check.ts). Then print its version.
//
// Exit non-zero, with a clear message on standard error, when either check
// fails. Print only the version string on standard output on success.
//
// Mount this file at a path inside the target image's server directory and
// run it there with `node`, so module resolution walks the same
// `node_modules` tree the running server itself resolves from:
//
//   docker run --rm \
//     -v "$PWD/scripts/assert-cloud-image-sentry.mjs:/app/server/.ci-sentry-probe.mjs:ro" \
//     --entrypoint node <image> /app/server/.ci-sentry-probe.mjs
