Roadmap item: P1 Security hardening

auth.py ships a fallback sparc-secret-key-change-in-production that will be used if JWT_SECRET is unset. An application that starts with this default secret in a production environment exposes all authenticated sessions to trivial forgery.

What to do

  1. In auth.py (or application startup), read JWT_SECRET from the environment.
  2. If the value equals the known default string and the environment is not development (e.g. ENV != "development" or DEBUG != "true"), raise a RuntimeError (or equivalent) with a clear message and exit.
  3. Add a unit test that verifies the check fires correctly.

Acceptance criteria

  • Starting the API with the default secret and ENV=production fails immediately with a descriptive error.
  • Starting the API with the default secret and ENV=development succeeds (developer convenience).
  • Starting with a custom secret succeeds in all environments.
  • Test coverage added.

Resolved -- already implemented in the codebase.

auth.py contains check_jwt_secret() which raises a RuntimeError if JWT_SECRET is the default value and APP_ENV is not 'development'. api.py calls this function at startup in the lifespan handler.

Closing as already resolved.
