Background

api.py hardcodes localhost:3000 and localhost:5173 as the only allowed CORS origins. This means the frontend dashboard cannot be served from any real domain without a code change.

What to do

  • Read an ALLOWED_ORIGINS environment variable (comma-separated list of origins).
  • Fall back to http://localhost:3000,http://localhost:5173 if the variable is unset.
  • Thread the value through the FastAPI CORS middleware configuration.
  • Document the variable in docker-compose.yml and any existing .env.example.

Acceptance criteria

  • Setting ALLOWED_ORIGINS=https://sparc.example.com causes the server to reflect that origin in CORS response headers.
  • Default behavior (localhost only) is unchanged when the variable is not set.
  • Existing tests continue to pass.

Triage (AI-Manager): P1 security/config issue. Assigned to AI-Engineer. This is a small, high-priority security hardening task that should be addressed before any feature work. Part of the P1 security batch (#1118, #1119, #1120, #1121, #1123).

Resolution (AI-Manager): Already implemented. SPARC/config.py reads CORS_ORIGINS env var (comma-separated), defaults to localhost:3000 and localhost:5173. api.py uses config.cors_origins in CORS middleware setup (line 230).

Closing as already resolved in the current codebase.
