+
+## 4. Horas Trabajadas (Automático desde Bookings)
+
+### 4.1 Cálculo Automático
+
+Las horas trabajadas por staff se calculan automáticamente desde bookings completados:
+
+```typescript
+async function getStaffWorkHours(staffId: string, periodStart: Date, periodEnd: Date) {
+  const { data: bookings } = await supabase
+    .from('bookings')
+    .select('start_time_utc, end_time_utc')
+    .contains('staff_ids', [staffId])
+    .eq('status', 'completed')
+    .gte('start_time_utc', periodStart.toISOString())
+    .lte('start_time_utc', periodEnd.toISOString());
+
+  const totalMinutes = bookings.reduce((sum, booking) => {
+    const start = new Date(booking.start_time_utc);
+    const end = new Date(booking.end_time_utc);
+    return sum + (end.getTime() - start.getTime()) / 60000;
+  }, 0);
+
+  return totalMinutes / 60; // Return hours
+}
+```
+
+### 4.2 Integración con Nómina
+
+El cálculo de nómina utiliza estas horas automáticamente:
+
+```typescript
+base_salary = staff.hourly_rate * work_hours
+commission = total_revenue * (staff.commission_rate / 100)
+```
+
+---
+
+## 5. POS System Specifications
+
+### 5.1 Características Principales
+
+**Carrito de Compra:**
+- Soporte para múltiples productos/servicios
+- Cantidad por item
+- Descuentos aplicables
+- Subtotal, taxes (si aplica), total
+
+**Métodos de Pago:**
+- Efectivo (con cálculo de cambio)
+- Tarjeta (Stripe)
+- Transferencia bancaria
+- Gift Cards
+- Membresías (créditos del cliente)
+- Pagos mixtos (combinar múltiples métodos)
+
+**Múltiples Cajeros:**
+- Each staff can open a POS session
+- Track cashier per transaction
+- Close day per cashier or per location
+
+### 5.2 Flujo de Cierre de Caja
+
+1. Solicitar fecha y location_id
+2. Calcular total ventas del día
+3. Breakdown por método de pago
+4. Verificar conciliación (esperado vs real)
+5. Generar PDF reporte
+6. Marcar day como "closed" (opcional flag)
+
+---
+
+## 6. Webhooks Stripe
+
+### 6.1 Endpoints
+
+**Endpoint:** `POST /api/webhooks/stripe`
+
+**Headers:**
+- `Stripe-Signature`: Signature verification
+
+**Events:**
+- `payment_intent.succeeded`: Payment completed
+- `payment_intent.payment_failed`: Payment failed
+- `charge.refunded`: Refund processed
+
+### 6.2 payment_intent.succeeded
+
+**Actions:**
+1. Extract metadata (booking details)
+2. Verify booking exists
+3. Update `payments` table with completed status
+4. Update booking `deposit_paid = true`
+5. Create audit log entry
+6. Send confirmation email/WhatsApp (si configurado)
+
+### 6.3 payment_intent.payment_failed
+
+**Actions:**
+1. Update `payments` table with failed status
+2. Send notification to customer
+3. Log failure in audit logs
+4. Optionally cancel booking or mark as pending
+
+### 6.4 charge.refunded
+
+**Actions:**
+1. Update `payments` table with refunded status
+2. Send refund confirmation to customer
+3. Log refund in audit logs
+4. Update booking status if applicable
+
+---
+
+## 7. No-Show Logic
+
+### 7.1 Ventana de Cancelación
+
+**Regla:** 12 horas antes de la cita (UTC)
+
+### 7.2 Detección de No-Show
+
+```typescript
+async function detectNoShows() {
+  const now = new Date();
+  const windowStart = new Date(now.getTime() - 12 * 60 * 60 * 1000); // 12h ago
+
+  const { data: noShows } = await supabase
+    .from('bookings')
+    .select('*')
+    .eq('status', 'confirmed')
+    .lte('start_time_utc', windowStart.toISOString());
+
+  for (const booking of noShows) {
+    // Check if customer showed up
+    const { data: checkIn } = await supabase
+      .from('check_ins')
+      .select('*')
+      .eq('booking_id', booking.id)
+      .single();
+
+    if (!checkIn) {
+      // Mark as no-show
+      await markAsNoShow(booking.id);
+    }
+  }
+}
+```
+
+### 7.3 Penalización Automática
+
+**Actions:**
+1. Mark booking status as `no_show`
+2. Retain deposit (do not refund)
+3. Send notification to customer
+4. Log action in audit_logs
+5. Track no-show count per customer (for future restrictions)
+
+### 7.4 Override Admin
+
+Admin puede marcar un no-show como "exonerated" (perdonado):
+- Status remains `no_show` but with flag `penalty_waived = true`
+- Refund deposit if appropriate
+- Log admin override in audit logs
+
+---
+
+## 8. Seguridad y Permisos
+
+### 8.1 RLS Policies
+
+**Admin:**
+- Full access to all tables
+- Can override no-show penalties
+- Can view all financial data
+
+**Manager:**
+- Access to location data only
+- Can manage staff and bookings
+- View financial reports for location
+
+**Staff/Artist:**
+- View own bookings and schedule
+- Cannot view customer PII (email, phone)
+- Cannot modify financial data
+
+**Kiosk:**
+- View only availability data
+- Can create bookings with validated data
+- No access to PII
+
+### 8.2 API Authentication
+
+**Admin/Manager/Staff:**
+- Require valid Supabase session
+- Check user role
+- Filter by location for managers
+
+**Public:**
+- Use anon key
+- Only public endpoints (availability, services, locations)
+
+**Cron Jobs:**
+- Require CRON_SECRET header
+- Service role key required
+
+---
+
+## 9. Performance Considerations
+
+### 9.1 Database Indexes
+
+```sql
+-- Critical indexes
+CREATE INDEX idx_bookings_customer ON bookings(customer_id);
+CREATE INDEX idx_bookings_staff ON bookings USING GIN(staff_ids);
+CREATE INDEX idx_bookings_status_time ON bookings(status, start_time_utc);
+CREATE INDEX idx_payments_booking ON payments(booking_id);
+CREATE INDEX idx_payments_status ON payments(status);
+CREATE INDEX idx_audit_logs_entity ON audit_logs(entity_type, entity_id);
+```
+
+### 9.2 N+1 Prevention
+
+Use explicit joins for related data:
+```typescript
+// BAD - N+1 queries
+const bookings = await supabase.from('bookings').select('*');
+for (const booking of bookings) {
+  const customer = await supabase.from('customers').select('*').eq('id', booking.customer_id);
+}
+
+// GOOD - Single query
+const bookings = await supabase
+  .from('bookings')
+  .select(`
+    *,
+    customer:customers(*),
+    service:services(*),
+    location:locations(*)
+  `);
+```
+
+---
+
+## 10. Testing Strategy
+
+### 10.1 Unit Tests
+
+- Generador de Short ID (collision detection)
+- Cálculo de depósitos (200 vs 50% rule)
+- Cálculo de nómina (salario base + comisiones + propinas)
+- Disponibilidad de staff (horarios + calendar events)
+
+### 10.2 Integration Tests
+
+- API endpoints (GET, POST, PUT, DELETE)
+- Stripe webhooks
+- Cron jobs (reset invitations)
+- No-show detection
+
+### 10.3 E2E Tests
+
+- Booking flow completo (customer → kiosk → staff)
+- POS flow (items → payment → receipt)
+- Dashboard navigation y visualización
+- Calendar drag & drop
+
+---
+

+### 21.5 Accesibilidad con Radix UI
+
+**ARIA Attributes Automáticos:**
+```typescript
+// Radix UI agrega automáticamente:
+// - role="button" para botones
+// - aria-expanded para dropdowns
+// - aria-selected para tabs
+// - aria-checked para checkboxes
+// - aria-invalid para inputs con error
+// - aria-describedby para errores de formulario
+
+// Ejemplo con manejo de errores:
+<Select>
+  <SelectTrigger aria-invalid={hasError} aria-describedby={errorMessage ? 'error-message' : undefined}>
+    <SelectValue />
+  </SelectTrigger>
+  {errorMessage && (
+    <p id="error-message" className="text-sm text-[#D73A49]">
+      {errorMessage}
+    </p>
+  )}
+</Select>
+```
+
+**Keyboard Navigation:**
+```typescript
+// Radix UI soporta automáticamente:
+// - Tab: Navigate focusable elements
+// - Enter/Space: Activate buttons, select options
+// - Escape: Close modals, dropdowns
+// - Arrow keys: Navigate within components (lists, menus)
+// - Home/End: Jump to start/end of list
+
+// Para keyboard shortcuts personalizados:
+useEffect(() => {
+  const handleKeyDown = (e: KeyboardEvent) => {
+    if ((e.metaKey || e.ctrlKey) && e.key === 'k') {
+      e.preventDefault()
+      // Open search modal
+    }
+  }
+  window.addEventListener('keydown', handleKeyDown)
+  return () => window.removeEventListener('keydown', handleKeyDown)
+}, [])
+```

+## 22. Guía de Migración a Radix UI
+
+### 22.1 Componentes que Migrar
+
+**De Headless UI a Radix UI:**
+- `<Dialog />` → `@radix-ui/react-dialog`
+- `<Menu />` → `@radix-ui/react-dropdown-menu`
+- `<Tabs />` → `@radix-ui/react-tabs`
+- `<Switch />` → `@radix-ui/react-switch`
+
+**Componentes Custom a Mantener:**
+- `<Card />` - No existe en Radix
+- `<Table />` - No existe en Radix
+- `<Avatar />` - No existe en Radix
+- `<Badge />` - No existe en Radix
+
+### 22.2 Patrones de Migración
+
+```typescript
+// ANTES (Headless UI)
+<Dialog open={isOpen} onClose={() => setIsOpen(false)}>
+  <DialogPanel>
+    <DialogTitle>Title</DialogTitle>
+    <DialogContent>...</DialogContent>
+  </DialogPanel>
+</Dialog>
+
+// DESPUÉS (Radix UI)
+<Dialog open={isOpen} onOpenChange={setIsOpen}>
+  <DialogContent>
+    <DialogTitle>Title</DialogTitle>
+    <DialogContent>...</DialogContent>
+  </DialogContent>
+</Dialog>
+```
+
