## Issue Closure Tracking

### Auth & Security (GG-126)

**GG-126: Resync Endpoint Missing Authentication**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.3)
- **Story:** GALA-4.6
- **Files Modified:** `routes/api.php`, `app/Http/Controllers/VenueController.php`
- **Change:** Added `auth:api` middleware to `/api/venues/{id}/resync` endpoint
- **Verification:** Feature test in `tests/Feature/API/VenueResyncAuthTest.php` (8+ tests)
- **Security Impact:** ✓ Prevents unauthenticated resync operations

---

### Database Schema (GG-130, GG-139, GG-142)

**GG-130: Schema Has Dual Constraints**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.2)
- **Story:** GALA-4.2
- **Migration:** `2026_01_12_110000_add_venue_fork_data_to_events_table.php`
- **Change:** Removed duplicate FK constraint, kept primary unique index
- **Schema Impact:** ✓ Cleaner schema, no constraint conflicts
- **Database Tests:** Constraint verification tests pass

**GG-139: Foreign Key Constraint Not Implemented**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.2)
- **Story:** GALA-4.2
- **Migration:** `2026_01_12_110000_add_venue_fork_data_to_events_table.php`
- **Change:** Added FK from `events.source_template_id` to `events.id`
- **Referential Integrity:** ✓ Ensures fork source exists
- **Cascade Behavior:** ON DELETE RESTRICT (prevents orphaned forks)

**GG-142: Template Version Mismatch Not Handled**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.4)
- **Story:** GALA-4.3
- **Service:** `GalaForkService::resync()` (line 345-360)

- **Verification:** `GalaHasChangesException` tested and logged

---

### Business Logic Guards (GG-132, GG-133, GG-134)

**GG-132: Checkout Grace Period Not Configurable**
- **Status:** ✅ FIXED
- **Batch:** BATCH 3 (Task 3.1)
- **Story:** GALA-4.10
- **Config File:** `config/booking.php` (line 10)
- **Change:** Added `gala_checkout_grace_period_seconds` to config
- **Default:** 300 seconds (5 minutes)
- **Usage:** `CheckoutGuardService::hasActiveCheckout()` queries this value
- **Verification:** Config is read and applied in service

**GG-133: Template Publish Blocking Incomplete**
- **Status:** ✅ FIXED
- **Batch:** BATCH 3 (Task 3.2)
- **Story:** GALA-4.12
- **Exception:** `TemplatePublishBlockedException`
- **Service:** `GalaStateService::forceTransitionTo()` line 145
- **Change:** Prevents transition from `on_sale` to `published`
- **Verification:** Exception tests verify blocking behavior

**GG-134: Resync Checkout Protection Incomplete**
- **Status:** ✅ FIXED
- **Batch:** BATCH 2 (Task 2.2)
- **Story:** GALA-4.10
- **Service:** `CheckoutGuardService::hasActiveCheckout()`
- **Implementation:**
  - Checks pending seat reservations (held, not expired)
  - Checks pending payment orders (PENDING_PAYMENT, PAYMENT_PROCESSING)
  - Applies grace period from config
- **Integration Points:**
  - `GalaForkService::resyncWithGuard()`
  - `ForceResyncSeats` CLI command
  - API resync endpoint
- **Verification:** 8 unit tests + feature tests + CLI tests

---

### Functional Features (GG-135, GG-136, GG-137, GG-138)

**GG-135: Table Reservations Incomplete**
- **Status:** ✅ FIXED
- **Batch:** BATCH 2 (Task 2.1)
- **Story:** GALA-4.7
- **Service:** `GalaTableBookingService`
- **Implementation:**
  - `bookTable()` - Creates reservations for all seats atomically
  - `releaseTableSeats()` - Cancels all reservations for table
  - `isTableAvailable()` - Checks all children availability
  - `getTableSeats()` - Lists parent + all children
- **Atomicity:** Uses `DB::transaction()` (lines 60, 95)
- **Verification:** 18 unit tests + atomic rollback tests

**GG-136: Table Cancellation Missing**
- **Status:** ✅ FIXED
- **Batch:** BATCH 2 (Task 2.1)
- **Story:** GALA-4.7
- **Service:** `GalaTableBookingService::releaseTableSeats()`
- **Implementation:**
  - Releases all held seats for table
  - Updates status to `released`
  - Logs operation with seat count
- **Verification:** Cancellation tests verify all seats released

**GG-137: Partial Availability Calculation Broken**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.1)
- **Story:** GALA-1.7
- **Service:** `GalaAvailabilityService::getAvailability()`
- **Fix:** Correctly excludes table parent seats from capacity
- **Calculation:** Only counts individual seats + table children
- **Verification:** 25+ availability tests + performance tests

**GG-138: hasChanges() Price Calculation Incorrect**
- **Status:** ✅ FIXED
- **Batch:** BATCH 1 (Task 1.1)
- **Story:** GALA-4.3
- **Service:** `GalaForkService::hasChanges()` (line 340)
- **Fix:** Compares `venue_fork_data` snapshot with current state
- **Verification:** Tested in resync operation tests

---

### Performance Optimizations (GG-140, GG-141)

**GG-140: Observer N+1 Query Batching**
- **Status:** ✅ FIXED
- **Batch:** BATCH 3 (Task 3.3)
- **Story:** GALA-4.11
- **Service:** `VenueSyncService` (line 441)
- **Implementation:**
  - Batch seat mutations into single observer trigger
  - Uses `withoutObservers()` pattern (when available)
  - Manually calls `invalidateAvailability()` after batch
- **Performance Impact:** Reduces queries from N to ~3 for bulk operations
- **Verification:** Performance test verifies query count

**GG-141: CLI Command Guard Integration**
- **Status:** ✅ FIXED
- **Batch:** BATCH 3 (Task 3.4)
- **Story:** GALA-4.6
- **Command:** `php artisan seats:force-resync`
- **Implementation:**
  - Integrates `CheckoutGuardService`
  - Prompts confirmation if checkout active
  - `--force` flag bypasses guard
  - Logs all operations to 'gala' channel
- **Guard Behavior:**
  - Blocks resync if held reservations exist
  - Blocks resync if payment in progress
  - Respects grace period from config
  - Asks user for confirmation (safe default: no)
- **Verification:** 15 unit tests cover all paths
