"""
Quality check layer for translations.

Tracks:
  A1 — L0 backend (pure Python, no API calls). Always available.
  A2 — L0 frontend JavaScript mirror. Browser/Node compatible.
  A3 — L1 LLM judge (API-based, opt-in). Cheap model, sampled.

Designed to be ADDITIVE: existing translation flow is untouched.

Public API:
  L0:
    QualityCheckResult         — per-chunk result dataclass
    DocumentQualityResult      — aggregated result dataclass
    evaluate_chunk(...)        — score a single (source, translation) pair
    evaluate_document(...)     — score a list of pairs and aggregate
    run_l0_check(...)          — defensive wrapper used by the route
    extract_sample(...)        — extract text from a finished file
  L1:
    L1Result                   — verdict dataclass
    LLMJudge                   — judge client
    run_l1_check(...)          — async wrapper used by the route
    sample_chunks_for_l1(...)  — pick representative chunks
  Helpers:
    get_script, isArabicScriptLang
