"""
legend-c420 PoC - PraisonAI 4.6.33 generates Flask API server with auth
disabled by default. Class H sibling of CVE-2026-44338.

Phase 1: reflect on praisonai.deploy.models.APIConfig defaults.
Phase 2: call generate_api_server_code(default config) and assert the
         emitted source contains AUTH_ENABLED = False and the
         short-circuit return.
Phase 3: re-run with auth_enabled=True, auth_token='s3cret-bearer-value'
         and confirm the emitted source flips to the secure shape.

Exit code 0 = PASS = vulnerable defaults confirmed.
