verify_prompt8_authentication_samples.py

Lancia gli 8 sample di verifica contro il proxy MoralStack locale e produce
un riepilogo PASS/FAIL.

Funziona su Windows, Linux, macOS — qualsiasi sistema con Python 3 installato.

Prerequisiti:
  - server_quickstart attivo su http://localhost:8787 con il Prompt 8 applicato
  - I payload q51..q58_payload.json + q74_full.json + q74_no_contract.json devono
    essere nella stessa directory dello script (o passa --payload-dir)

Uso:
  python verify_prompt8_authentication_samples.py
  python verify_prompt8_authentication_samples.py --payload-dir C:\\path\\to\\payloads
  python verify_prompt8_authentication_samples.py --proxy http://localhost:8080/chat/completions
