"""
Test suite per Intervento A: fix della logica has_ambiguity_or_dual_use
in _build_policy_context_pre (decision_service.py).

BUG: harm_type != "none" da solo attiva has_ambiguity_or_dual_use=True,
causando SAFE_COMPLETE su domande puramente informative che menzionano
un harm_type (es. "Quali sono le conseguenze della frode fiscale?").

FIX PROPOSTO in _build_policy_context_pre:
  PRIMA:
    has_ambiguity_or_dual_use = (
        misuse_plausibility in ("MEDIUM", "HIGH")
        or actionability_risk in ("MEDIUM", "HIGH")
        or (harm_type != "" and harm_type != "none")        # troppo aggressivo
    )
  DOPO:
    has_ambiguity_or_dual_use = (
        misuse_plausibility in ("MEDIUM", "HIGH")
        or actionability_risk in ("MEDIUM", "HIGH")
        or (
            harm_type not in ("", "none", "emotional_relational")
            and (intent_operational or requested_instructions)  # condizionato
        )
    )

NOTA TECNICA: requested_instructions e' un campo di RiskParseResult ma NON
di RiskEstimation. decision_service lo legge via getattr(..., False).
Per i test che necessitano requested_instructions=True usiamo un wrapper.

Struttura:
  1. Regressione benchmark (casi che FALLISCONO prima del fix, PASSANO dopo)
  2. Safety preservation (PASSANO sia prima che dopo il fix)
  3. Boundary conditions
  4. Invarianza (percorsi non coinvolti)
  5. White-box su _build_policy_context_pre
