Hardened authentication middleware inside `services/01-physics-engine/index.js` to reject weak, default, or insecure secrets (`dev_secret_change_in_production`, `test_secret`, `dev_secret`, `default_secret`, `secret`) in production environments (`process.env.NODE_ENV === 'production'`) with a 500 configuration/internal server error. Created a dedicated security unit test suite in `services/01-physics-engine/security.test.js` using Jest and supertest to verify weak secret rejection, achieving 100% test compliance (3/3 tests green) and ensuring zero regressions.

This PR implements zero-trust JWT secret hardening for the L1 Physics Engine microservice. Following the established pattern across the platform, we reject known insecure/default keys under production mode to safeguard the physics training data and prevent token forging. Added a robust security unit test suite with 100% success.

Note
Medium Risk
Changes authentication behavior for all JWT-protected physics-engine endpoints in production; misconfigured deploys will fail closed on those routes, while health checks remain unaffected.
Overview
Production JWT hardening for the L1 Physics Engine: authenticated routes now refuse to run when
NODE_ENV=productionandJWT_SECRETis missing or matches a known weak/default value, returning 500 with a generic configuration error instead of verifying tokens with an insecure key.Adds
WEAK_SECRETS/isWeakSecret()and wires the check at the start ofauthenticateToken(e.g./data/training/physics)./healthstays unauthenticated.New
security.test.jscovers health without auth, production + weak secret → 500 on a protected route, and production + strong secret → successful export.Reviewed by Cursor Bugbot for commit 71903e3. Configure here.
