+# Implementation Summary: Timezone Fix + Per-Space Settings
+
+## Overview
+Fixed timezone display issues and added per-space scheduling settings to the space booking system.
+
+## Changes Implemented
+
+### Part A: Frontend Timezone Fix ✅
+
+**File: `frontend/src/utils/datetime.ts`**
+- Added `ensureUTC()` function to handle naive datetime strings from backend
+- Applied `ensureUTC()` to all `new Date()` calls in:
+  - `formatDateTime()`
+  - `formatTime()`
+  - `formatDateTimeWithTZ()`
+  - `isoToLocalDateTime()`
+
+**File: `frontend/src/views/Dashboard.vue`**
+- Imported `ensureUTC` from utils
+- Applied to booking date comparisons in `upcomingBookings` computed property
+
+**Impact:** MyBookings now correctly shows times in user's timezone (e.g., 10:00-17:00 Bucharest instead of 08:00-15:00 UTC).
+
+---
+
+### Part B: Per-Space Scheduling Settings (Database) ✅
+
+**File: `backend/app/models/space.py`**
+- Added 4 nullable columns:
+  - `working_hours_start` (Integer)
+  - `working_hours_end` (Integer)
+  - `min_duration_minutes` (Integer)
+  - `max_duration_minutes` (Integer)
+
+**File: `backend/app/schemas/space.py`**
+- Added 4 optional fields to `SpaceBase` and `SpaceResponse`
+
+**File: `backend/migrations/004_add_per_space_settings.sql`**
+- Created migration (already applied to database)
+
+**Impact:** Spaces can now override global settings. NULL = use global default.
+
+---
+
+### Part C: Timezone-Aware Validation ✅
+
+**File: `backend/app/services/booking_service.py`**
+- Imported `Space` model and timezone utilities
+- Added `user_timezone` parameter to `validate_booking_rules()`
+- Load per-space settings with fallback to global
+- Convert UTC times to user timezone for working hours validation
+- Fix max bookings per day to use local date boundaries
+
+**File: `backend/app/api/bookings.py`**
+Updated 6 endpoints to pass `user_timezone`:
+
+1. **POST /bookings (create)** - Line ~251
+2. **POST /bookings/recurring** - Line ~376
+   - Also fixed: Now converts local times to UTC before storage
+3. **PUT /bookings/{id} (update)** - Line ~503
+4. **PUT /admin/.../approve** - Line ~682
+   - Uses booking owner's timezone
+5. **PUT /admin/.../update** - Line ~865
+   - Uses booking owner's timezone
+6. **PUT /admin/.../reschedule** - Line ~1013
+   - Uses booking owner's timezone
+
+**Impact:**
+- Working hours validation now uses user's local time (9:00 Bucharest is valid, not rejected as 7:00 UTC)
+- Per-space settings are respected
+- Recurring bookings now store correct UTC times
+
+---
+
+### Part D: Admin UI for Per-Space Settings ✅
+
+**File: `frontend/src/views/Admin.vue`**
+- Added form section "Per-Space Scheduling Settings"
+- Added 4 input fields with placeholders indicating global defaults
+- Updated `formData` reactive object
+- Updated `startEdit()` to load space settings
+- Updated `resetForm()` to clear settings
+- Added CSS for form-section-header, form-row, and help-text
+
+**File: `frontend/src/types/index.ts`**
+- Extended `Space` interface with 4 optional fields
+
+**Impact:** Admins can now configure per-space scheduling rules via UI.
+
+---
+
+## Testing Checklist
+
+### Timezone Display
+- [ ] User with `Europe/Bucharest` timezone sees correct local times in MyBookings
+- [ ] Booking created at 09:00 Bucharest shows as 09:00 (not 07:00)
+
+### Working Hours Validation
+- [ ] Booking at 09:00 Bucharest (07:00 UTC) is accepted (not rejected by 8-20 rule)
+- [ ] User sees error message with correct timezone-aware hours
+
+### Per-Space Settings
+- [ ] Create space with custom working hours (e.g., 10-18)
+- [ ] Booking outside custom hours is rejected
+- [ ] Space without settings uses global defaults
+- [ ] Admin UI displays and saves per-space settings correctly
+
+### Recurring Bookings
+- [ ] Recurring bookings now store correct UTC times
+- [ ] Bookings created for multiple occurrences have consistent timezone handling
+
+---
+
+## Files Modified
+
+| # | File | Changes |
+|---|------|---------|
+| 1 | `frontend/src/utils/datetime.ts` | Added `ensureUTC()` + applied to 4 functions |
+| 2 | `frontend/src/views/Dashboard.vue` | Import and use `ensureUTC` |
+| 3 | `backend/app/models/space.py` | Added 4 nullable columns |
+| 4 | `backend/app/schemas/space.py` | Added 4 optional fields |
+| 5 | `backend/migrations/004_add_per_space_settings.sql` | DB migration (applied) |
+| 6 | `backend/app/services/booking_service.py` | Timezone-aware validation |
+| 7 | `backend/app/api/bookings.py` | Updated 6 callers + recurring fix |
+| 8 | `frontend/src/views/Admin.vue` | Admin UI for per-space settings |
+| 9 | `frontend/src/types/index.ts` | Extended Space interface |
+
+---
+
+## Known Limitations
+
+1. **SQLite**: COMMENT ON COLUMN not supported (documented in migration file)
+2. **Backward Compatibility**: Existing bookings created before fix may have incorrect times (data migration not included)
+
+---
+
+## Next Steps
+
+1. Run frontend ESLint: `cd frontend && npx eslint src/utils/datetime.ts src/views/Dashboard.vue src/views/Admin.vue`
+2. Run backend tests: `cd backend && pytest` (if tests exist)
+3. Manual testing per checklist above
+4. Consider data migration for existing bookings if needed

+# Testing Guide - Spaces & Dashboard Implementation
+
+## Application Status
+
+✅ **Backend**: Running on http://localhost:8000
+✅ **Frontend**: Running on http://localhost:5174
+✅ **API Tests**: All endpoints working correctly
+
+## Test Data
+
+### Users
+- **Admin**: admin@example.com / adminpassword
+- **User**: user@example.com / userpassword
+
+### Spaces
+- Biblioteca Colorata 1 (sala, capacity: 20) - Active
+- Biblioteca Colorata 2 (sala, capacity: 20) - Active
+
+### Bookings
+- Test Meeting - Tomorrow at 10:00 (Pending approval)
+
+---
+
+## Manual Testing Steps
+
+### 1. Test Dashboard Page (`/`)
+
+**As Admin User:**
+
+1. Open http://localhost:5174 in your browser
+2. Login with: admin@example.com / adminpassword
+3. You should see the **Dashboard** with:
+   - ✅ **Quick Stats Cards:**
+     - Total Bookings: 1
+     - Pending: 1
+     - Approved: 0
+     - Pending Requests: 1 (admin only)
+
+   - ✅ **Quick Actions Section:**
+     - "Book a Space" button → links to /spaces
+     - "My Bookings" button → links to /my-bookings
+     - "Manage Bookings" button (admin only) → links to /admin/bookings
+     - "Manage Spaces" button (admin only) → links to /admin/spaces
+
+   - ✅ **Upcoming Bookings Card:**
+     - Shows "Test Meeting" for tomorrow at 10:00
+     - Displays space name "Biblioteca Colorata 1"
+     - Shows status badge "Pending"
+     - Has "View All" link to /my-bookings
+
+   - ✅ **Available Spaces Card:**
+     - Shows 2 active spaces
+     - Each space clickable → navigates to /spaces/:id
+     - Displays type and capacity
+     - Has "View All" link to /spaces
+
+   - ✅ **Recent Activity Card (admin only):**
+     - Shows last 3-5 audit log entries
+     - Displays action, user, and timestamp
+     - Has "View All" link to /admin/audit-log
+
+**Expected Behavior:**
+- Loading spinner appears briefly while fetching data
+- All cards display correctly with accurate data
+- Links navigate to correct pages
+- Admin-only sections visible only to admin users
+
+---
+
+### 2. Test Spaces Page (`/spaces`)
+
+1. Navigate to http://localhost:5174/spaces (or click "Book a Space" from Dashboard)
+2. You should see:
+   - ✅ **Page Header:**
+     - Title: "Available Spaces"
+     - Subtitle: "Browse and reserve meeting rooms and desk spaces"
+
+   - ✅ **Filters:**
+     - Type dropdown: All Types / Desk / Meeting Room / Conference Room
+     - Status dropdown: All / Active Only
+
+   - ✅ **Spaces Grid:**
+     - 2 space cards displayed in responsive grid
+     - Each card shows:
+       - Space name (e.g., "Biblioteca Colorata 1")
+       - Active/Inactive badge
+       - Type icon and label
+       - Capacity icon and count
+       - Description (truncated to 100 chars)
+       - "View Details" button
+
+   - ✅ **Card Interactions:**
+     - Hover effect: card lifts up with shadow
+     - Click anywhere on card → navigates to /spaces/:id (detail page)
+
+**Test Filtering:**
+- Change Type filter → cards update (currently all are "sala", so mapping may show as is)
+- Change Status to "Active Only" → shows only active spaces (both visible)
+- Empty filters → should show "No Spaces Found" message
+
+**Expected Behavior:**
+- Loading spinner while fetching spaces
+- Cards render in a responsive grid (3 columns on desktop, 1 on mobile)
+- Clicking a card navigates to SpaceDetail page with calendar
+- Empty state shows when no spaces match filters
+
+---
+
+### 3. Test Space Detail Page (`/spaces/:id`)
+
+1. From Spaces page, click on any space card
+2. You should see:
+   - ✅ **Breadcrumbs:** Home / Spaces / [Space Name]
+   - ✅ **Space header** with name, badges (type, capacity, status)
+   - ✅ **Reserve Space button** (already implemented)
+   - ✅ **Description card** (if space has description)
+   - ✅ **Availability Calendar** (already implemented)
+
+**Expected Behavior:**
+- Page loads space details correctly
+- Calendar shows existing bookings
+- Reserve button is functional
+
+---
+
+### 4. Test as Regular User
+
+1. Logout (if logged in as admin)
+2. Login with: user@example.com / userpassword
+3. **Dashboard should show:**
+   - ✅ Quick stats (Total, Pending, Approved) - WITHOUT "Pending Requests" card
+   - ✅ Quick actions - WITHOUT "Manage Bookings" and "Manage Spaces" buttons
+   - ✅ Upcoming Bookings - empty or only user's bookings
+   - ✅ Available Spaces - same 2 spaces
+   - ✅ NO "Recent Activity" section
+
+4. **Spaces page should work identically** for regular users
+
+**Expected Behavior:**
+- Admin-specific features hidden for regular users
+- All other functionality works the same
+
+---
+
+## Automated Test Results
+
+```
+✅ All API endpoints tested successfully
+✅ Spaces page: Can display 2 spaces with filtering
+✅ Dashboard stats: Total: 1, Pending: 1, Approved: 0
+✅ Upcoming bookings: 1 upcoming bookings
+✅ Available spaces: 2 active spaces
+✅ Admin features: 1 pending requests, 3 recent logs
+✅ ESLint: No errors
+```
+
+---
+

+
+## Known Limitations
+
+1. **Type mapping**: Backend uses "sala" type, frontend expects "desk/meeting_room/conference_room"
+   - Current workaround: formatType() function handles both
+   - Consider aligning backend types with frontend expectations
+
+2. **Empty bookings**: Test data has only 1 booking
+   - To test full functionality, create more bookings via UI or API
+
+3. **Time zones**: Dates displayed in UTC
+   - Future enhancement: format according to user's timezone
+
+---
+
+## Next Steps
+
+1. ✅ Spaces.vue - **IMPLEMENTED**
+2. ✅ Dashboard.vue - **IMPLEMENTED**
+3. 🔜 Booking creation flow (US-004d)
+4. 🔜 My Bookings page
+5. 🔜 Admin booking management
+
+---
+
