[CLAUDE] FE-Admin: Chunk pre-A — Mig 31 prep: rename slot label "#NV {order}" -> "Họ tên" user pin

UX polish trong ApprovalWorkflowsV2Page Designer slot label hiển thị tên user pin
(lookup từ usersList query) thay vì số thứ tự "NV #{ei + 1}". Fallback "Chưa chọn NV"
khi slot chưa pick user.

Plan K pre-Mig 31 first chunk. Mig 31 sẽ thêm AllowApproverSkipToFinal 7th checkbox
inline panel (K3 chunk sau).

Per bro decision S23 t1: "Chỗ quy trình duyệt #NV 1 - Họ tên luôn".

Verify:
- npm run build fe-admin pass
- 0 TS error

+- **2026-05-14 (S23 t1, Chunk pre-A PASS):** UI polish slot label Designer Mig 31 prep. File `fe-admin/src/pages/system/ApprovalWorkflowsV2Page.tsx` line 873 replaced `Quyền duyệt NV #{ei + 1}` → `Quyền duyệt {usersList.data?.find(u => u.id === entry.approverUserId)?.fullName ?? 'Chưa chọn NV'}`. Pattern: lookup user fullName từ `usersList` query (Option A — DTO `EditLevelEntry` không có `approverFullName` field, chỉ `LevelDto` BE response có `approverUserName` nhưng edit state dùng `EditLevelEntry`). `usersList` đã in scope ~line 500, pattern lookup `.find(x => x.id === e.approverUserId)` đã dùng tại line 535 cho validation. Cookie-cutter 1 file fe-admin only (fe-user KHÔNG có Designer per Investigator K0 S1). Tailwind classes preserved (`mb-1 text-[10px] font-medium uppercase text-amber-700`). Verify: `npm run build` fe-admin PASS clean 0 TS error, 0 new warning. Bundle 1395 KB (unchanged trivial). Token ~5k.
 - **2026-05-13 (S22, REFUSED 100%):** Em main classified ALL S22 work as cross-stack reasoning chain (BE Mig + Service guard + DTO + FE Designer + FE Section + FE types + tests) → REFUSE per criteria #3+#4. Em main solo executed. State chốt S22: **30 migrations** (+1 Mig 30 AllowApproverEditSection1 per-NV F4 flag), **104 test PASS** (+20 từ 84 — gồm PE WF ReturnMode + Draft guard + Reflection-based Authorize policy regression), ~146 endpoints (+3), 46 gotchas unchanged, 33 active prod users (13 cũ + 20 mới S22+2). 7 patterns successfully applied throughout S22 (validated continued effectiveness): Pattern 7 per-NV admin opt-in flag (Mig 30 follow Mig 29), Pattern 2 EF migration 3-file rule, Pattern 8 tách endpoint narrow scope (AdjustBudget vs UpdatePeDraft), Pattern 9 defense-in-depth FE+BE guard pair (S22+1 disable 3 button), Pattern 10 Reflection-based regression test cho Authorize policy (Plan C task 4 #44, 5 test ~50 LOC), Pattern 11 test infra helper cookie-cutter (SeedWorkflowAsync + SeedApproversAsync), Pattern 12 InternalsVisibleTo csproj expose internal helper cho test. Mismatches discovered S22: (1) "Đang trong quá trình duyệt = người điều chỉnh cũng là người duyệt" — em first interpret default Approver scope always allowed → bro corrected per-NV admin opt-in flag (Mig 30). Lesson: clarify default behavior vs admin opt-in TRƯỚC khi default scope expansion. (2) `PE.changelogs` field KHÔNG có trong PeDetailBundle — em first design history display trong BudgetAdjustSection, build FAIL TS2339. Fix: removed history display (defer S23+ via separate fetch endpoint). (3) Dialog `size="xl"` NOT supported — only "sm" | "md" | "lg". Use "lg" cho preview iframe. (4) API auth field `accessToken` không phải `token`. Script `seed-test-users-prod.ps1` lần đầu FAIL 401 sau auth — em fix `$authResp.accessToken`.
 - **2026-05-13 (S21 t3-t5, REFUSED 3×):** Em main classified all 3 turns as cross-stack reasoning chain (BE+FE+test tightly coupled) → REFUSE per criteria #3+#4 (cross-stack > 2 layers, bug fix reasoning chain). Bug fix gotcha #45 = bug + reasoning, F1+F2+F3 = schema design decision, Refactor per-NV = drastic refactor schema + Service + FE × 2 app. All correct REFUSE — em main solo executed. Strict scope criteria validated S21 t3-t5 — REFUSE rate 100% match Anthropic warning "tightly interdependent coding". Cumulative: 84 test, 29 mig, 45 gotcha. Pattern saved future invocation: per-NV permission scope split natural theo role + EF migration BACKFILL reorder pattern.
 - **2026-05-11 (setup):** Implementer agent initialized. Baseline knowledge load complete (5 patterns proven cumulative S1-S20: per-chunk 5 chunk, 3-file rule Mig, audit-reuse clone, service hook derived state, FE mirror 2 app, VND format helpers). No implementations performed yet. Awaiting first SendMessage from em main. Strict scope auto-refuse criteria active.
