+
+## Đợt 1 — Batch CV PRO 6-fix (Run #334 `5a61254`)
+
+File `Cần chỉnh sửa CV PRO.xlsx` = **8 ảnh chú-thích nhúng** (zip xl/media/, KHÔNG phải bảng công thức) — đọc qua skill xlsx + giải-nén + Read ảnh. 6 fix → AskUserQuestion chốt 3 nhóm mơ-hồ:
+- **C1** ẩn "c.Giá chào thầu" + "d.Bảng so sánh giá" khỏi form TẠO (giữ ở Detail).
+- **C3** ô8 "Giá trị TH dự kiến còn lại" pre-fill từ dòng7 (Ngân sách còn lại).
+- **C4a** **live-recompute** — `VndInlineEdit +onLiveChange`, `PeBudgetSummaryTable draftRow3/draftRow8` → dòng 5/6/7/9 + % nhảy NGAY khi gõ ô3/8 (chưa cần Lưu).
+- **C4b** So-sánh=0 → "Bằng ngân sách"/"—" (chỉ khi base>0).
+- **C5** hủy/đổi NCC winner — BE `SelectWinnerBody(Guid?)` + Command/Handler clear-branch (null=clear bỏ-validate-list, no-migration vì SelectedSupplierId đã Guid?) + FE dropdown ""→null + nút ✓ toggle.
+- **C7** nút "Toàn màn hình" preview file báo giá (overlay inset-0 + Esc).
+
+Test +10 (`PeSelectWinnerClearTests`) → 356→366. FE 3 file ×2 app SHA-identical (diff-confirm rồi cp).
+
+## Đợt 2 — Clear sạch UAT data (`scripts/s85-wipe-uat-data.sql`)
+
+anh Kiệt "Clear sạch giúp anh nhé. Clear truoc em, xong anh check." Quy-trình destructive-prod chuẩn S59: recon → AskUserQuestion chốt scope → script → chạy → verify exact-count.
+- **Recon prod:** 43 PE + 28 PeWorkItemBudgets + 1 HĐ + 32 notif + 43 Suppliers (22 gốc ≤06-09 + 21 test ≥06-11).
+- anh chốt: **xóa budgets (28)** + **xóa 21 NCC-test** (CreatedAt≥06-11, mốc cắt sạch 06-10 trống).
+- Script: **BACKUP bước 0** (registry backup-dir vì D:\ không tồn-tại VPS) + `SET QUOTED_IDENTIFIER ON` (filtered-index Mig19/20) + `SET XACT_ABORT ON` + `-b` (backup-fail→abort-trước-wipe). Verify exact: PE/budgets/contracts/notif=0, Suppliers=22, reset mã→A/001. DemoSeed:Disabled gate → app-recycle KHÔNG resurrect.
+- Orphan upload files **defer** (path CWD-relative chưa pin, vô-hình UAT).
+
+## Đợt 3-6 — 6 vòng UAT (#335→#338)
+
+- **R1 #335 `24f0083`:** D1 ẩn mục 3/4/5 (gỡ FormRow/LockedHint/Lock unused) + D5 auto-chọn quy trình khi 1 option (prod PE type-1 có đúng 1 selectable WF).
+- **R2 #336 `a5e936f`:** D2 drafter tự-gỡ cờ GẤP — BE restructure SET/UNSET (GẮN role-only; GỠ +drafter clear-CẢ-2) + FE `isDrafter` canToggle. D3 ngân-sách-kỳ-này tự-nhảy từ "Ban hành lần đầu" (`proInitialAmount`) — FE display + FE/BE submit-guard fallback `budgetPeriodAmount ?? proInitialAmount`. test +5 (`PeUrgentToggleAuthzTests` drafter-self-unset) → 366→371.
+- **R3 #337 `e3e40ae`:** ràng tạo-phiếu (hint đỏ "thiếu: Quy trình/Hạng mục/Dự án", anh "không chọn quy trình thì ko cho tạo phiếu") + D4 checklist xanh✓/đỏ✗ trường bắt-buộc gửi-duyệt (mirror missingForApproval). [JSX fragment fix: chèn nhầm conditional trùng → bọc `<>`.]
+- **R4 #338 `34218f0`:** checklist +"Quy trình duyệt" (sót → toàn-xanh-nhưng-submit-chặn misleading). [R4 auto-assign-at-submit thử → REVERT vì phá 2 test S83 + nới block ngược "ràng".]
+
+## Đợt 7-8 — 2 ROOT-CAUSE (whack-a-mole → fix gốc)
+
+**(R5 #339 `1263c0d`) Workflow MẤT khi bấm Sửa = bug-class S42** — gotcha #73.
+- long.chau + anh Kiệt vẫn kẹt "chưa chọn quy trình" DÙ SQL-fix 5 phiếu. Query prod: 2 phiếu workflow-less MỚI (A/005 14:54, A/010 15:08) tạo SAU SQL-fix → KHÔNG phải point-in-time, là systemic.
+- Truy: form Sửa header → `PUT /purchase-evaluations/{id}` (PeHeaderForm:112) KHÔNG gửi `approvalWorkflowId` → `UpdatePeDraftHandler:282` absolute-set `= null` = CLEAR. Field SÓT khỏi pattern null-safe mà BudgetPeriodAmount/WorkItemId cạnh đã có (S42).
+- Fix: `if (request.ApprovalWorkflowId is not null) entity.ApprovalWorkflowId = ...`. Test +3 (`PeUpdateDraftWorkflowPreserveTests`) → 371→374.
+
+**(R6 #341 `49ac086`) "Mới tạo báo 7h trước" = TZ +7h** — gotcha #72.
+- timestamps UTC nhưng EF đọc `DateTimeKind.Unspecified` → System.Text.Json serialize KHÔNG 'Z' → FE `new Date(naive)`=local → lệch +7h.
+- Fix: global `UtcDateTimeJsonConverter` (AddControllers.AddJsonOptions) ép UTC-with-Z `.ToString("O")`. cicd verify API trả `createdAt:"…3154440Z"`. (= ops "tzutil UTC+7" pending S58, fix tầng-serialize chuẩn hơn đổi giờ máy-chủ.)
+
+**5 SQL-fix** (2 đợt 3+2 phiếu workflow-less): `UPDATE PurchaseEvaluations SET ApprovalWorkflowId='E08E3DA6…' WHERE ApprovalWorkflowId IS NULL AND Type=1` (QT-DN-V2-001). Bridge tới khi R5 deploy.

+### 72. DateTime serialize KHÔNG có 'Z' (EF đọc `Unspecified` kind) → FE `new Date()` hiểu là local → lệch +7h (Session 85)
+
+**Triệu chứng:** anh Kiệt "mới tạo phiếu mà báo cách 7h trước" — relative-time thông-báo (`Date.now() - new Date(createdAt).getTime()`) lệch đúng +7h (VN UTC+7).
+
+**Cơ chế:** timestamps lưu UTC (`DateTime.UtcNow`) nhưng EF Core đọc SQL Server `datetime2` về `DateTimeKind.Unspecified`. `AddControllers()` mặc-định (KHÔNG JSON config) → System.Text.Json serialize DateTime Unspecified-kind **KHÔNG có hậu-tố 'Z'** (`"2026-06-23T08:20:00"`). FE `new Date(naive)` hiểu chuỗi-không-TZ là **giờ LOCAL** → nhưng giá-trị là UTC → lệch +7h. Build PASS + test xanh (serialization không unit-test) → CÂM.
+
+**Guard:** global `JsonConverter<DateTime>` ép UTC-with-Z: `Kind==Unspecified ? SpecifyKind(Utc) : ToUniversalTime()` → `.ToString("O")`. Đăng-ký `AddControllers().AddJsonOptions(o => o.JsonSerializerOptions.Converters.Add(new UtcDateTimeJsonConverter()))`. System.Text.Json tự áp cho `DateTime?` (Nullable non-null). **Verify:** curl authed endpoint → field `createdAt` JSON CÓ 'Z'. Lưu-UTC + convert-on-display (FE) là CHUẨN — KHÔNG band-aid `tzutil` đổi giờ máy-chủ (ảnh-hưởng GETUTCDATE + lệch khác). SignalR realtime-push dùng serializer RIÊNG (`AddJsonProtocol`) → nếu giờ realtime còn lệch thì áp converter tương-tự.

+**Triệu chứng:** phiếu tạo CÓ Quy trình duyệt → bấm "Sửa" (đổi tên/dự án) → MẤT workflow → kẹt submit "chưa chọn quy trình duyệt" (**whack-a-mole**: SQL-fix vá xong, ai bấm Sửa lại rụng tiếp). long.chau + anh Kiệt + nhiều account.
+
+**Cơ chế:** `UpdatePeDraftHandler` absolute-set `entity.ApprovalWorkflowId = request.ApprovalWorkflowId`. Form Sửa (PeHeaderForm) KHÔNG gửi `approvalWorkflowId` → command bind `null` (default `Guid? = null`) → handler set `= null` = **CLEAR**. Field SÓT khỏi pattern null-safe (`if (request.X is not null)`) mà `BudgetPeriodAmount`/`ExpectedRemainingAmount`/`WorkItemId` NGAY DƯỚI đã có (comment "client không gửi → GIỮ giá trị cũ" — bug-class S42). 1 field lọt khỏi quy-ước đã-thiết-lập.
+
+**Guard:** MỌI field optional trong UPDATE-handler PHẢI null-safe `if (request.X is not null) entity.X = request.X` (preserve khi không gửi); CHỈ field text-clearable CỐ-Ý (TenGoiThau/DiaDiem/MoTa) mới absolute-set. Khi thêm field vào UPDATE command → **đối-chiếu pattern null-safe của field cạnh**.
