[CLAUDE] Domain+App+Infra+Api+FE-Admin+FE-User: S36 Plan G-O2 Phòng họp Mig 36 + BE CRUD + FE 2 app

Phase 10.2 G-O2 Phòng họp BookingCalendar — Mig 36 schema + BE CQRS + FE 2 app
mirror cookie-cutter G-H2 HrmConfig pattern. Standalone không depend workflow.

BE schema (Mig 36 — em main solo Step 4):
- 4 Domain new: MeetingRoom catalog + MeetingBooking header + MeetingBookingAttendee
  join table N-to-N (NOT JSON per Investigator verdict) + Enums (MeetingBookingStatus
  3-state: Confirmed/Cancelled/Completed)
- 3 EF Config: UNIQUE Code + composite index (RoomId, StartAt) range query + UNIQUE
  composite (BookingId, UserId) join
- FK strategy: Room→Restrict (preserve history) + Booking→Cascade attendees +
  User→Restrict (denorm FullName+Email tránh cascade wipe)
- Mig 36 3-file rule + ApplicationDbContextModelSnapshot updated + apply Dev+Design DB

BE CQRS (~584 LOC — Implementer Case 2):
- MeetingFeatures.cs 479 LOC 9 handler: 4 Room CRUD + 5 Booking (List + GetById +
  Create + Update + Cancel)
- SERIALIZABLE transaction overlap check via EXISTS query — throw 409 Conflict
  "Phòng đã được đặt trong khoảng thời gian này"
- MeetingRoomsController 49 LOC + MeetingBookingsController 56 LOC — class-level
  [Authorize] + Roles="Admin" for write
- Application.csproj +Microsoft.EntityFrameworkCore.Relational package (em main fix
  IsolationLevel overload — Implementer gotcha #53 4th truncation diagnose mid-task)
- MenuKeys.cs +4 const (Off_PhongHop sub-group + View/Manage/Book leaf)
- DbInitializer +SeedMeetingRoomsAsync 4 sample (PH-A Phòng họp lớn cap=20 + PH-B
  cap=8 + PHG-501 Giám đốc cap=6 + ONL-1 Online Zoom cap=50) — NOT gated DemoSeed
  per gotcha #51 INFRASTRUCTURE seed

FE 2 app (~1770 LOC × 2 — Implementer Case 2):
- types/meeting.ts × 2 SHA256 IDENTICAL (ce0ad9c6d017cde2) — DTO interface mirror
- MeetingCalendarPage.tsx × 2 SHA256 IDENTICAL (d6d160ae1e4f2285) ~530 LOC — custom
  HTML 7-day grid 8h-20h slot, NO FullCalendar dep (~80 KB bundle saved per
  Investigator verdict alternative)
- MeetingRoomsPage.tsx × 2 SHA256 IDENTICAL (ba35a7ef379a5e9c) ~270 LOC — admin
  catalog CRUD table + Dialog
- 4-place mirror Pattern 16-bis 7× cumulative: types + page + App.tsx route +
  menuKeys + Layout staticMap 3 entry (gotcha #50 silent sidebar drop prevention)

Verify:
- dotnet build SolutionErp.slnx PASS 0 error 2 pre-existing DocxRenderer warning
- dotnet test 130/130 PASS baseline preserve (58 Domain + 72 Infra)
- npm build × 2 app PASS 0 TS error (fe-admin 16.91s bundle 1490 KB / fe-user 8.56s
  bundle 1404 KB, +23 KB gzip both)

Pattern reinforced cumulative S36:
- Pattern 12-bis cross-module mirror 10× (PE → Contract V2 → Hrm → Office)
- Pattern 16-bis 4-place mirror cross-app 7×
- Smart Friend Implementer truncation gotcha #53 4th — mitigation tight brief WORK
  (FE 2 app no truncation, BE truncate diagnose mid only)
