Whitespace secrets skip weak check
Low Severity
The new isWeakSecret helper treats a falsy secret as weak, but a JWT_SECRET that is only whitespace is truthy before trim(), so it is not flagged and production auth can proceed with an empty effective signing key.

Note
Medium Risk
Changes production authentication behavior—misconfigured or default JWT secrets will return 500 on all protected routes until fixed, which is intentional but deployment-sensitive.
Overview
L4 Market Gateway v3.9.0 tightens JWT auth and test bootstrapping for the wholesale market service.
authenticateTokennow resolves the active secret from env, fails with 500 whenJWT_SECRETis missing, and in production rejects known weak/default values viaWEAK_SECRETS/isWeakSecretinstead of verifying tokens with insecure keys. Service version is bumped to 3.9.0 inpackage.json,/health, and bidding halt log strings inBiddingOptimizer.js.start()runs only when the process is the main module (require.main === module), so Jest canrequire('./index')without listening or starting background work. A newsecurity.test.jssuite (Redis/pg/Kafka mocked) covers/health, production weak/default secret rejection on protected routes, and successful auth with a strong secret.An August 2026 weekly engineering report documents the security sprint and backlog closure.
