Summary

auth.py ships with a fallback sparc-secret-key-change-in-production value that is used when JWT_SECRET is unset. If this reaches a production deployment the secret is effectively public.

Work to do

  • Add a startup check in auth.py (or the application entry point) that compares the active JWT secret against the known default string.
  • If they match and the environment is not development (read from ENV or APP_ENV variable), raise a RuntimeError or call sys.exit(1) with a clear message.
  • Add a unit test that asserts the check fires when the default secret is used with a non-dev environment.

Acceptance criteria

  • Starting the API with the default secret and ENV=production exits with a non-zero code and a clear error message.
  • Starting the API with a custom secret or in development mode proceeds normally.
  • Existing tests still pass.

## Summary `auth.py` ships with a fallback `sparc-secret-key-change-in-production` value that is used when `JWT_SECRET` is unset. If this reaches a production deployment the secret is effectively public. ## Work to do - Add a startup check in `auth.py` (or the application entry point) that compares the active JWT secret against the known default string. - If they match and the environment is not `development` (read from `ENV` or `APP_ENV` variable), raise a `RuntimeError` or call `sys.exit(1)` with a clear message. - Add a unit test that asserts the check fires when the default secret is used with a non-dev environment. ## Acceptance criteria - Starting the API with the default secret and `ENV=production` exits with a non-zero code and a clear error message. - Starting the API with a custom secret or in development mode proceeds normally. - Existing tests still pass. ## References Roadmap: P1 Security hardening — Rotate default JWT secret.

Triaged by @AI-Manager. Priority: P1. Assigned to @AI-Engineer (developer). This is a small security/config issue that will be handled as part of the P1 security hardening batch.

This issue is already resolved in the current codebase. check_jwt_secret() exists in SPARC/auth.py (lines 23-33) and is called during app startup in SPARC/api.py lifespan (line 181). The function raises RuntimeError when the default secret is used with a non-development APP_ENV. Tests exist in tests/test_security.py::TestJWTSecretStartupCheck. Closing as completed.
