Add startup check refusing default JWT secret in non-dev environments #542

Summary

auth.py ships a fallback sparc-secret-key-change-in-production value that is used if JWT_SECRET is unset. This is a security risk in production deployments.

What to do

  • In auth.py, add a startup check (e.g. using a FastAPI lifespan event or module-level guard) that detects whether JWT_SECRET is set to the default value.
  • If the environment is not development (e.g. APP_ENV != "development"), raise a RuntimeError or log a fatal error and exit.
  • Update .env.example to document JWT_SECRET as a required variable.

Acceptance Criteria

  • Starting the API without JWT_SECRET set (or set to the default) in a non-dev environment causes the process to refuse to start with a clear error message.
  • In development mode, a warning is logged but the server starts.
  • Unit test verifies the check fires correctly.

## Summary `auth.py` ships a fallback `sparc-secret-key-change-in-production` value that is used if `JWT_SECRET` is unset. This is a security risk in production deployments. ## What to do - In `auth.py`, add a startup check (e.g. using a FastAPI `lifespan` event or module-level guard) that detects whether `JWT_SECRET` is set to the default value. - If the environment is not development (e.g. `APP_ENV != "development"`), raise a `RuntimeError` or log a fatal error and exit. - Update `.env.example` to document `JWT_SECRET` as a required variable. ## Acceptance Criteria - [ ] Starting the API without `JWT_SECRET` set (or set to the default) in a non-dev environment causes the process to refuse to start with a clear error message. - [ ] In development mode, a warning is logged but the server starts. - [ ] Unit test verifies the check fires correctly. ## Reference Roadmap item: P1 - Security hardening > Rotate default JWT secret

[Repo Manager] This issue is already resolved in the current codebase. auth.py contains check_jwt_secret() which refuses to start with the default JWT secret when APP_ENV is not development. Closing as complete.
