+// Supplier Phase B — SupplierExcelImportService (import NCC từ file "Database NCC").
+// TEST-BEFORE-MERGE: CRITICAL-ALGO (parser layout-locked + upsert) + BUG-FIX class
+// (case-collation dedup) → tests bắt buộc trước commit (docs/rules.md §7).
+//
+// Test theo CODE trên đĩa (S34 single-source-of-truth). KHÔNG sửa production code —
+// nếu test lộ bug prod thật → REPORT em main, không tự fix.
+//
+// 🔴 BUG-CLASS (Case 1): unique-index Code ở SQL Server = case-INSENSITIVE. Nếu service
+//    so Ordinal, "truonggiang" (file) ≠ "TRUONGGIANG" (DB) → miss → quyết INSERT →
+//    ConfirmAsync nổ unique-violation → 500 cả batch. Service dùng OrdinalIgnoreCase ở
+//    cả preview + confirm để chặn. Test chứng minh dedup CI hoạt động (chỉ 1 NCC, update
+//    tại chỗ, không insert hàng thứ 2).
+//    LƯU Ý collation: SQLite (fixture) mặc định BINARY (case-SENSITIVE) → DB-level unique
+//    KHÔNG bắt "truonggiang" vs "TRUONGGIANG". Đó chính là điểm test: dedup phải nằm ở
+//    SERVICE (in-memory OrdinalIgnoreCase), KHÔNG dựa DB — nếu dựa DB thì prod SQL Server
+//    sẽ ném 500. Test này xanh chứng tỏ service không dựa DB.
+//
+// ⚠️ SPEC-DRIFT đã biết (không phải bug tôi phát hiện): service.ExpectedHeaderTokens hiện
+//    là BEST-GUESS, CHƯA khớp 30 token row-4 thật của file (sẽ sửa ở close-review adjust).
+//    → Các test cần "valid layout" (Case 4-7) DỰNG header từ chính ExpectedHeaderTokens
+//    của service (đọc qua REFLECTION) nên LUÔN đồng bộ — không vỡ khi tokens được sửa.
+//    → Case 9 (PreviewAsync_RealFileRow4Tokens...) nạp 30 token THẬT và khẳng định
+//    PreviewAsync đồng ý với so-khớp-fingerprint trực tiếp: hiện tại lệch → LayoutValid=false;
+//    khi tokens sửa = token thật → tự động khẳng định LayoutValid=true (không phải sửa test).
