[CLAUDE] Domain+App+Api+Infra+FE-Admin+FE-User: S34 Plan 2 G-O1 Danh bạ nội bộ

Phase 10.2 Văn phòng số — Internal Directory (1 endpoint reuse Users +
EmployeeProfiles + Departments, FE card grid avatar/dept/email/phone/Ext).

BE Task 1+2 (em main solo):
- Application/Office/DirectoryFeatures.cs — GetDirectoryQuery + DirectoryItemDto
  12 field LEFT JOIN Users.IsActive + Departments + EmployeeProfiles
- Api/Controllers/DirectoryController.cs — GET /api/directory?search=&departmentId=
  class-level [Authorize] (mọi authenticated NV tra cứu danh bạ nội bộ)
- MenuKeys.cs +Off+OffDanhBa const + All[] update
- DbInitializer.SeedMenuTreeAsync Off Order=29 + OffDanhBa Order=1 dưới Off

FE Task 3 (Implementer Case 2 Pattern 16-bis 4-place mirror cross-app — 5×):
- types/directory.ts SHA256 7349d9f64e78 × 2 app IDENTICAL
- pages/office/InternalDirectoryPage.tsx SHA256 2aa7e0eed2c8 × 2 app IDENTICAL
  Card grid responsive 1/2/3/4 col + filter dept dropdown + search input
  Avatar 14×14 initials gradient PALETTE 6 màu (Pattern 14 Tailwind JIT)
  EmployeeCode badge + Department emerald badge + email mailto + phone tel
  Internal phone Ext: amber badge + empty/loading state Vietnamese 100%
- App.tsx route /directory × 2 app
- lib/menuKeys.ts Off+OffDanhBa const × 2 app
- components/Layout.tsx resolvePath staticMap Off_DanhBa:/directory × 2 app
  (gotcha #50 — 5 places mirror crossapp DON'T MISS)

Verify:
- dotnet build PASS (2 warn DocxRenderer existing, 0 error)
- dotnet test 120/120 PASS (58 Domain + 62 Infra baseline preserve)
- npm build × 2 app PASS 0 TS err (fe-admin 1436KB / fe-user 1350KB)

Implementer MEMORY Pattern 16-bis reinforced 5× cumulative (S29 Plan CA HF1 +
S29 Plan B Chunk D + S33 Plan B G-H1 Task 5 + S34 Plan G-O1 Task 3).

Endpoint smoke pending CICD post-deploy Stage 4 (Run #XXX expected ~3m30s).
