Add startup check to reject default JWT secret in non-dev environments #568

Context

auth.py ships with a fallback secret sparc-secret-key-change-in-production that is used when the JWT_SECRET environment variable is unset. In production this is a critical security vulnerability — any instance that starts without setting JWT_SECRET will use a publicly known secret.

What to do

  1. In the application startup path (e.g., FastAPI lifespan or a startup event), check whether JWT_SECRET matches the default value.
  2. If the environment is NOT development (e.g., APP_ENV != "development"), raise a RuntimeError or log a CRITICAL message and exit with a non-zero code.
  3. Add a unit test that asserts the startup check fires with the default secret in a non-dev environment.

Acceptance criteria

  • Starting the API with the default secret and APP_ENV=production causes a clean fatal error with a descriptive message.
  • Starting in development mode with the default secret logs a warning but does not block startup.
  • Existing tests continue to pass.

## Context `auth.py` ships with a fallback secret `sparc-secret-key-change-in-production` that is used when the `JWT_SECRET` environment variable is unset. In production this is a critical security vulnerability — any instance that starts without setting `JWT_SECRET` will use a publicly known secret. ## What to do 1. In the application startup path (e.g., FastAPI `lifespan` or a startup event), check whether `JWT_SECRET` matches the default value. 2. If the environment is NOT development (e.g., `APP_ENV != "development"`), raise a `RuntimeError` or log a `CRITICAL` message and exit with a non-zero code. 3. Add a unit test that asserts the startup check fires with the default secret in a non-dev environment. ## Acceptance criteria - Starting the API with the default secret and `APP_ENV=production` causes a clean fatal error with a descriptive message. - Starting in development mode with the default secret logs a warning but does not block startup. - Existing tests continue to pass. ## Reference Roadmap: P1 — Security hardening

Triage Note: Part of the security hardening group (#568, #569, #570). These three issues are independent and can be worked in parallel, but all should be completed before #574 (auth tests).

Priority: P1 | Complexity: small | Assigned agent type: @developer

Triage (AI-Manager): P1 security hardening issue. Assigned to @AI-Engineer (developer role). This is a small, well-scoped change. Should be implemented on a dedicated feature branch and submitted as a PR to the fork.
