#!/usr/bin/env python3
"""
v5.0 Production Readiness Expert Test Harness (Faza 4 Golden Dataset + Verification Layers).

Usage:
    python backend/scripts/v5_readiness_test.py --subset 8 --silent
    python backend/scripts/v5_readiness_test.py --full --report json > v5_readiness_report.json

Runs end-to-end flows on Golden Dataset subset:
- search+match (light / mocked with expected)
- generate light sections (using helpers.generate_section_light + company profile)
- audit (light path where possible)
- trap + cite verify (CitationVerifier + Kruczkowski + data_quality)
- resume simulation (checkpoint / generator resume logic)

Computes:
  citation_faithfulness (avg support_score from verifier)
  trap_precision (detected vs expected traps overlap)
  no_hallucination_rate (1 - fraction of low data_quality + unsupported claims)
  resume_success (fraction of simulated resumes that preserve state without crash)
  trust_score_avg (from trust_scorer using citation + data_quality)

Exits 0 if all aggregate thresholds met (pragmatic for CI), else 1 with details.
Silent-friendly: --silent suppresses per-case logs except summary + critical errors.
