[CLAUDE] FE-Admin: redesign Phase 1 — density-first design system (NAMGROUP-ref, giữ brand)

Tham khảo NAMGROUP density conventions, GIỮ brand #1F7DC1 + Be Vietnam Pro.
- index.css: density heading ladder (semibold, drop font-bold) + .label-eyebrow util
- 6 UI primitives (Button/Input/Label/Select/Textarea/Dialog): text-xs font-semibold, py-1.5 ≤36px, rounded-lg, brand focus-ring
- 6 shell (DataTable sticky-thead+RowActions/Layout brand-rail/TopBar/PageHeader/PhaseBadge/EmptyState)
- DashboardPage flagship: KPI cards + brand-tinted icon chips + uppercase labels

Visual-only — functionality unchanged (Button variant/size keys stable 51 call-sites, props/forwardRef intact). build 0 TS err. reviewer PASS 0 blocker (2 minor slate-400 hint a11y defer). fe-admin only (fe-user mirror = Phase 3). Dashboard live-visual blocked by dev auth-rig → xem live sau deploy.

+- **S55 (2026-06-09) Phase-1 fe-admin redesign — density-first NAMGROUP-ref, KEEP brand [em main proxy — designer truncated gotcha #53 trước build/MEMORY]:** Applied 14 file: index.css (density heading ladder semibold + `.label-eyebrow` 11px uppercase slate-500 + drop font-bold) + 6 ui primitives (Button `text-xs font-semibold rounded-lg` h-7/8/10 + brand focus-ring/70 — variant/size keys STABLE 51 call-sites) + 6 shell (DataTable/Layout/TopBar/PageHeader/PhaseBadge/EmptyState) + DashboardPage (KPI card `rounded-lg border-slate-200` + `bg-brand-50` icon chip h-7w7 + uppercase tracking-wider label + brand accent bar). Brand #1F7DC1 + Be Vietnam Pro KEPT (NAMGROUP density = mượn cấu trúc, brand=ours). `npm run build` 0 TS err. **Visual loop BLOCKED** by authed-rig gotcha (3) above → CHỈ chụp /login (polished, on-brand). em main recover: build ✓ + login-visual ✓ + diff-review (index.css/Button/DashboardPage high-quality, brand-consistent).

 - **S47 (2026-06-02) FD2 RIG VERIFIED ✅** — first real spawn. Ran full FD2 loop end-to-end on fe-user `/login`: read DS (Tailwind v4 CSS-first, corrected stale config-path assumption) → started Vite via `with_server.py` → Playwright screenshot 375+1440 → Read PNGs → FD4 critique → 1-line contrast fix → re-screenshot confirmed → `npm run build` 0 TS error. Closes adap-report `2026-06-02-Agent-frontend-designer-floor` FD2 runtime proof. 2 Vite gotchas captured above. Loop is REAL, not theoretical.

"QTV" (DbInit:1458 RoleLabels) = ShortName DISPLAY label only = decoy. Program.cs JWT sets NO `RoleClaimType` override (ClaimTypes.Role symmetric write/read). Same proven pattern as every existing Roles="Admin" endpoint. **Bypass airtight:** controller any-auth → handler sole gate; guard `if(!isAdmin && !(itDeptId is Guid mine && myDeptId==mine)) Forbidden` fail-CLOSED when itDeptId null (non-admin blocked; admin still passes role-branch). `Department.Code=="IT"` IS seeded (DbInit:2082 "Phòng CNTT") so live non-null. **Capability 0-leak:** non-auth → `{canReassign:false, staff:[]}` (no name leak), `[Authorize]` any-auth → 0 silent-403. **Defense-in-depth intact:** FE nút `{canReassign&&}` but PUT still hits handler guard → 403/409 → `onError: toast.error(getErrorMessage(err))` surfaces (NOT swallowed). **FE SHA256 page 4bcaf2f IDENTICAL both apps** (types.ts correctly NOT identical — admin AttendanceReportDto vs user HrDashboardDto diverge below; added AssignableStaff block byte-identical); old fe-user page was read-only kanban (NO app-specific logic lost — diff purely additive); fe-user has all imports (apiError.getErrorMessage, Dialog size/footer/onClose props match, Select passthrough, sonner). **Test 13-fact NOT happy-path:** Case5 Forbidden side-effect assert `AssignedToUserId.Should().BeNull()` (red-able by contrast vs Case6/7 same-handler success), Case3/3b empty-staff 0-leak, Case8 Conflict msg-exact. prove-by-contrast ĐỦ CHẶT (partition non-IT-throws vs IT/admin-succeed identical handler). **1 MINOR defer:** assignee-must-IT NEW vs old handler (git HEAD: old allowed admin→ANY active user); itDeptId-null → even admin Conflict — fail-closed acceptable+spec-requested, cosmetic (prod IT-dept seeded). **Learned:** authz role-string review = trace FULL chain const→seed Name→GetRolesAsync(names not codes)→Claim(ClaimTypes.Role)→reader AND grep JWT cfg for `RoleClaimType` override (none=symmetric) — display-code (QTV) in RoleLabels/ShortName dict = classic decoy. **surprise:** moving authz controller→handler is the CORRECT gotcha #44 fix (not a smell) when paired with BE-computed capability flag for FE gating + handler as sole gate.
