+ * Spins up an auth-gateway proxy in front of the test backend that:

+ * CF-Access-Client-Secret (mirrors the real-world Cloudflare Access challenge),
+ * - otherwise reverse-proxies to the backend.
+ *
+ * Then runs `wmill sync push` with --base-url pointed at the proxy. If any fetch

+ * fails (or the request is logged as un-authenticated). Negative case verifies
+ * the gateway actually rejects un-headered requests, so a passing positive case
+ * is meaningful.

+ * Regression coverage for #6421 and the script.ts pushScript /
