Context

auth.py ships a fallback sparc-secret-key-change-in-production that will be used if JWT_SECRET is unset. This is a security risk in any non-development deployment.

Work

  • Add a startup check (e.g., in lifespan or app initialization) that inspects the JWT_SECRET environment variable.
  • If the value matches the known default and the environment is not development (check APP_ENV or similar), raise a RuntimeError or log a fatal message and exit.
  • Document the required env var in README or .env.example.

Acceptance Criteria

  • Starting the API without JWT_SECRET set (or with the default value) in a non-dev environment causes an immediate startup failure with a clear error message.
  • Setting a custom JWT_SECRET allows the API to start normally.
  • A development/test environment is not blocked by this check.

## Context `auth.py` ships a fallback `sparc-secret-key-change-in-production` that will be used if `JWT_SECRET` is unset. This is a security risk in any non-development deployment. ## Work - Add a startup check (e.g., in `lifespan` or app initialization) that inspects the `JWT_SECRET` environment variable. - If the value matches the known default and the environment is not `development` (check `APP_ENV` or similar), raise a `RuntimeError` or log a fatal message and exit. - Document the required env var in `README` or `.env.example`. ## Acceptance Criteria - Starting the API without `JWT_SECRET` set (or with the default value) in a non-dev environment causes an immediate startup failure with a clear error message. - Setting a custom `JWT_SECRET` allows the API to start normally. - A development/test environment is not blocked by this check. ## References Roadmap: P1 — Security hardening — Rotate default JWT secret.

Triaged by repo manager. Assigned to @AI-Engineer (developer). This is a small security-focused task: add a startup guard that refuses to run with the default JWT secret in non-development environments. P1 priority.

Already implemented. auth.py has check_jwt_secret() that refuses to start with the default JWT secret when APP_ENV is not 'development'. Closing.
