+- **2026-05-15 (S24 t1 spawn Pre-A — Plan AA User Workflow Matrix view + sidebar widen):** 5Q audit. Q1 endpoint: `ApprovalWorkflowsV2Controller.cs:16-19` đã class-level `[Authorize]` bare từ S18 2026-05-08 (gotcha #44 fixed permanent), per-method admin Workflows.Create. Handler `GetAwAdminOverviewQuery` KHÔNG có IsUserSelectable filter — cần ADD param + Where conditional. Q2 menu seed: `DbInitializer.cs:1429-1437` peOrder global increment (Group=1, leaves 2/3/4 cycle per type). Permission seed `line 1541-1547` cho 7 role (Drafter/DeptManager/Procurement/CostControl/ProjectManager/Director/AuthorizedSigner). Accounting NOT trong list — admin manual grant nếu cần. Q3 Admin Designer: `ApprovalWorkflowsV2Page.tsx` 975 lines, AwLevelDto 13 fields (7 Allow*), VI labels line 892-948 ("Trả về 1 Cấp trước"/"Trả về 1 Bước trước"/"Trả về Người chỉ định"/"Trả về Drafter (mặc định)"/"Cho phép chỉnh sửa Section 2 (Hạng mục/NCC/Báo giá) lúc đang duyệt"/"Cho phép chỉnh sửa Section ngân sách lúc đang duyệt"/"Cho phép duyệt thẳng Cấp cuối khi đang duyệt"). KHÔNG có usePermission/PermissionGuard wrap (class-level [Authorize] route guard sufficient). Q4 sidebar widen: fe-user `Layout.tsx:325` + fe-admin `Layout.tsx:218` `w-60 xl:w-72` (240/288px). PE Workspace 2-panel `[260px_1fr] xl:[320px_1fr]` (NOT 3-panel như memory `feedback_responsive_laptop_breakpoint` stale claim). After widen `w-72 xl:w-80` (288/320px) SAFE (sidebar 288 + main 992 → workspace 260+732 fit @ 1280px). `w-80 xl:w-96` THRESHOLD RISKY (sát 700px remaining). Q5 ApplicableType enum `ApprovalWorkflow.cs:45-50` {DuyetNcc=1, DuyetNccPhuongAn=2, Contract=3}. Surprises: (1) memory responsive breakpoint stale "3-panel" → cần update sau Plan AA. (2) Order strategy "Luồng duyệt" Order=2 first → shift existing leaves +1 → cần DbInitializer UPDATE Order existing (KHÔNG chỉ INSERT-if-not-exists). (3) Contract=3 chưa wire FE (chỉ DuyetNcc + DuyetNccPhuongAn). Recommendation: Proceed Plan AA — chỉ ADD param filter + 1 menu key + page mới + sidebar widen. Token cost ~32k.
 - **2026-05-15 (S23 t8 spawn Plan R pre-flight cleanup audit):** Bro chốt cleanup destructive prod. 4 sqlcmd queries audit: 35 PE total (28 active + 7 soft) + 17 V2 (15 IsUserSelectable=false + 2 ghim) + 4 V1 (2 active + 2 inactive). FK gotcha catch: PE.ApprovalWorkflowId Restrict + ApprovalWorkflow extends `BaseEntity` NO soft-delete → hard-DELETE required; LevelOpinion → ApprovalWorkflowLevel Restrict cascade block. SQL Express limit: NO COMPRESSION + RESTORE VERIFYONLY require sysadmin. Filtered indexes (Mig 29+) require `SET QUOTED_IDENTIFIER ON`. Cascade child estimate: 446 PE children + ~140 V2 + ~37 V1 = ~620 rows. 3 Option compare → bro chốt A (Hard-DELETE PE + V2 unghim + V1 inactive, GIỮ V2 ghim + V1 active). Plan F precedent: KHÔNG drop V1 active (PE pin → BE crash).
 - **2026-05-15 (S23 t6 spawn Plan P FE wire audit — confirm BE-only scope):** Em main hypothesize Plan P scope BE Controller body record drop. Investigator audit FE × 2 confirm: `PeWorkflowPanel.tsx:113-124` `api.post(/transitions, body)` SEND ĐÚNG 7 fields (TargetPhase + Decision + Comment + ReturnMode + ReturnTargetUserId + SkipToFinal). No service file (untyped object literal). BE `PurchaseEvaluationsController.cs:267` `TransitionPeBody` record CHỈ 3 fields → ASP.NET silent DROP 3 missing fields. Verdict: Plan P BE Controller ONLY ~6 LOC + no test (Mig 28/31 Domain test cover handler). Saved em main blind fix cross-stack.
 - **2026-05-15 (S23 t3 spawn — UAT bug Allow* flags không hiện cho actor non-row1):** Bro UAT login `nv.test@solutions.com.vn` vào menu eoffice "Duyệt NCC → Duyệt" phiếu PE/2026/A/026 (Phase=ChoDuyet, WF=QT-DN-V2-001 v12, ở Bước 2 Cấp 1 4 NV: Trần Xuân Lưu/NV Test UAT V2/Hồ Thị Nữ Nguyên/Lê Văn Bính). Admin ĐÃ tick 7 Allow*=TRUE riêng cho slot NV Test UAT V2. Nhưng FE dialog Duyệt KHÔNG hiện checkbox SkipToFinal + Trả lại 4 mode + Edit. **Verdict: HYPOTHESIS B — BE handler picks wrong slot row.** Evidence: (1) `PurchaseEvaluationFeatures.cs:765` `var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder);` — match FIRST row có `Level.Order == curLevelOrder`, NOT actor's row. Post-Mig 29 refactor, Level.Order trùng nhau cho mọi NV cùng Cấp (4 row có `Order=1` ở Step 2). EF returns Trần Xuân Lưu trước (PK order) → `FirstOrDefault` lấy row đó (all-false except Drafter=true). (2) API curl admin token + nv.test token return CÙNG `currentLevelOptions={ allowReturnOneLevel=false, OneStep=false, Assignee=false, Drafter=true, EditDetails=false, EditBudget=false, SkipToFinal=false }` — handler currentUser-agnostic confirm. (3) Workflow detail GET `/approval-workflows-v2?applicableType=1` `.types[0].active.steps[1].levels` enumerate 4 slot Bước 2 Cấp 1: NV Test (UAT V2) = ALL 7 TRUE; 3 NV còn lại = ALL FALSE (trừ Drafter=true mặc định). Admin Designer wire ĐÚNG (`fe-admin/src/pages/system/ApprovalWorkflowsV2Page.tsx:889-946` 7 checkbox per-slot). FE consumer wire ĐÚNG (`fe-user/src/components/pe/PeWorkflowPanel.tsx:51 levelOptions = evaluation.currentLevelOptions` + line 343/357/371/397 conditional render mode picker + line 425 SkipToFinal checkbox). **Root cause:** BE line 765 lookup semantic broken sau Mig 29 (S21 t5). Trước Mig 29, 1 Level row per Cấp + `ApproverUsers` join table → `FirstOrDefault(Order==X)` đúng. Sau Mig 29 split 1 Level row PER ApproverUser → `Order` field collide → cần match thêm `ApproverUserId == currentUser.UserId`. **Fix BE 1 dòng:** `var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder && l.ApproverUserId == currentUser.UserId);` (admin bypass: fallback `?? curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder)` để admin xem detail không lỗi). Edge case: Phase=DaDuyet/TraLai/TuChoi pointer null → existing guard line 760-762 skip block OK. **LOC ~2-3 LOC 1 file.** Surprise: bug PRESENT từ deploy Mig 29 (S21 t5 2026-05-13) — không phải regression S23. Lý do trước đây không bắt: UAT test users (default 13 cũ) đa số là row đầu của slot Cấp (Admin tick toàn FALSE → behavior giống nhau, không lộ); chỉ bộc lộ khi admin tick CHỌN LỌC per-NV (UAT V2 S22+2 thêm 20 user role-based + bro tick chỉ NV Test UAT V2). Cross-reference memory `feedback_per_nv_permission_scope.md` cumulative S21 t5 → S22+5 → S23 t1 — KHÔNG có entry nào nhắc bug lookup BE post-refactor.
