Context

auth.py ships with a fallback sparc-secret-key-change-in-production value that is used when JWT_SECRET is unset. If this reaches production, all tokens are trivially forgeable.

Roadmap reference: ROADMAP.md > P1 > Security hardening > Rotate default JWT secret

What to do

  1. In auth.py (or the application startup sequence), detect when the active JWT secret equals the known default string.
  2. If the environment is not development (check APP_ENV or ENVIRONMENT env var), raise a RuntimeError or call sys.exit(1) with a clear message.
  3. Add a unit test that asserts the startup check fires when the default is present outside dev mode.

Acceptance criteria

  • Starting the API with JWT_SECRET unset and APP_ENV=production results in immediate exit with a descriptive error.
  • Starting with JWT_SECRET unset and APP_ENV=development (or unset) succeeds.
  • Starting with a non-default JWT_SECRET value always succeeds.
  • Existing tests continue to pass.
