# Implementer-Frontend — L2 Archive 2026 H1 > Verbatim detail moved out of HOT `MEMORY.md` during S97 compaction (2026-07-01). > One-line hooks remain in `MEMORY.md`. Read here for full detail; search L3 RAG for older. --- ## 🆕 2026-07-12 — Supplier import Excel FE (Phase B Approach A) ×2 app byte-identical (lead chốt UX; BE done+450 tests) NEW `components/master/SupplierImportDialog.tsx` (folder `master/` MỚI cả 2 app) + wire `pages/master/SuppliersPage.tsx` (nút "Import Excel NCC" outline cạnh "Thêm NCC" trong PageHeader actions flex + render dialog). KHÔNG 4-place mirror — dialog trên page ĐÃ routed → no new route/menuKey/Layout. - **Flow:** .xlsx → POST `/suppliers/import/preview` multipart field `file` → preview. `layoutValid===false`→alert đỏ+warnings, ẩn nút xác nhận. Else: badge counts (New/Update/Skip/Error) + warnings amber + `` raw (Dòng·StatusBadge·Mã·Tên·Loại·Thông báo). "Xác nhận nhập" disabled `errorCount>0` → POST `/import/confirm` body `{rows}` = echo `preview.rows` VERBATIM. committed→toast+`invalidateQueries(['suppliers'])`+close; !committed→alert `errors[]`. - **BE contract (Read-only DTO):** enum serialize = **INT** (chỉ UtcDateTimeJsonConverter đăng ký, KHÔNG JsonStringEnumConverter) → `type` 1-6 reuse `SupplierTypeLabel`, `status` RowImportStatus 0-3 const-object; camelCase wire (default web JSON); confirm bind positional record `(IReadOnlyList Rows)`. Round-trip 30 field verbatim → TS type partial vẫn OK runtime. - **Mirror lesson (tái xác nhận S97-badge):** Dialog (fe-user gradient title bar) + PageHeader + types/master (khác MỖI `Department.parentId` admin-only S65) ĐỀU DIVERGED 2 app — NHƯNG import alias-path `@/…` + symbol-signature giống → new file VẪN byte-identical. Byte-identical SuppliersPage cũ (build 2 app) = proof mọi symbol tương thích. UI: KHÔNG shadcn Badge/Alert/Table primitive (chỉ PhaseBadge) → inline Tailwind badge/alert + `
`. Multipart = pattern `ContractAttachmentsSection` (FormData + `Content-Type: multipart/form-data`). - **SHA256 ×2 pair:** SupplierImportDialog `6313529c…`, SuppliersPage `e9143d93…`.

FIX: prop → `phase?: number` (literal `DaDuyet`=7 so-khớp OK; import vẫn dùng trong `=== …DaDuyet` → no unused). LESSON: list-DTO field mirror-BE = `number` rộng → prop nhận `number`, KHÔNG narrow-union; check kiểu item trước khi type prop. - **EDIT2 6 site (grep `PeFinalizeChip endsBeforeCeo` = 6, hết):** admin{PeListPanel:162, ListPage:492} + user{PeListPanel:162, ListPage:492, InboxPage:292, UserDashboardPage:286}.
