# Studio API & Auth Tests -- HTTP-level integration tests for the
# FastAPI surface. No Playwright, no model UI; tests/studio/test_studio_api_smoke.py
# runs ~30 s and asserts:
#   - CORS hardening (no wildcard + credentials, no bootstrap leak)
#   - /api/system + /api/system/hardware require auth
#   - Auth state machine + JWT expiry
#   - API key lifecycle E2E (create / list / use / delete / reject)
#   - Auth file-mode hardening (Linux only)
#   - Inference lifecycle (force reload, bogus variant, /v1/models, /v1/embeddings, /v1/responses)
#   - Endpoint-by-endpoint auth audit
#
# Reuses the GGUF cache key from studio-ui-smoke.yml so the model
# download is one cache-hit on the second job.
