# CC Soccer D11 - Session Handoff

**Last Updated:** January 21, 2026 - 9:30pm  
**Status:** ✅ Complete credits system implemented (Phases 1-5)

---

## ✅ COMPLETED: Full Credits System Implementation

### Phase 1-2: Credits Display and Admin
- Season Players page shows player credit balances
- Season Credits admin page for viewing all credits by season
- Credits entity updated with proper field definitions (amount in cents, status, source, reason)

### Phase 3: Cancel Registration with Credits
- New CancelRegistrationForm for admin cancellation workflow
- Issues credit to player when registration is cancelled
- Updates registration status and logs the action

### Phase 4: Automatic Rainout Credits
- GameStatusForm extended to issue credits when game marked as rainout
- Calculates credit amount based on (season_price / total_games) * 75%
- Dynamic UI shows affected players and credit amounts before confirmation
- Bulk credit issuance to all registered players for rained out games

### Phase 5: Checkout Credits Integration
- Dedicated credits step in checkout flow (between Agreements and Review)
- Players can apply credits, keep for later, or donate to league
- Shows no credits message when balance is zero
- Credits applied as order adjustment (reduces total)
- OrderCompleteSubscriber processes credit usage and donations on order completion

### Checkout Flow Fixes
- Fixed button labels using Commerce next_label pattern (label comes from destination step)
- Restored hidden payment step required by PaymentProcess pane for return/cancel URLs
- Fixed redirect loop by keeping payment_process on payment step
- Flow: Player Info -> Group -> Agreements -> Credits -> Review -> Payment -> Complete

### Bug Fixes
- Cancelled registrations no longer show as active on /register page
- Added status != cancelled filter to getSeasonState() and getTournamentState()

### Credit Manager Service
- Full rewrite to use cents internally (avoids floating point issues)
- Methods: issueCredit, issueRainoutCredit, issueCancellationCredit
- Methods: useCredits (FIFO), donateCredits, getUserBalanceCents
- Methods: calculateRainoutCreditCents, getSeasonCredits
- Added logging for all credit operations via @logger.factory

### Update Hooks Added
- 9042: Move ccsoccer_credits pane to dedicated credits step
- 9043: Ensure payment_process pane stays on payment step

## ✅ PREVIOUSLY COMPLETED: Cart Duplicate Prevention Fix

**Problem:** Users could add same season/tournament to cart multiple times, bypassing validation.

**Solution Implemented:**
- Created `CartEventSubscriber` to listen to `CartEvents::CART_ENTITY_ADD`
- Detects duplicates by checking if quantity > 1 (Commerce auto-combines)
- Forces quantity back to 1 and displays warning message

---

### Working Features
- ✅ Season registration (individual + groups)
- ✅ Tournament registration (captain + join team + CCSoccer pool)
- ✅ Unified group management (seasons + tournaments)
- ✅ Notification system (email + SMS with dev environment blocking)
- ✅ Credits system - FULL IMPLEMENTATION
  - ✅ View credits on Season Players page
  - ✅ Season Credits admin page
  - ✅ Cancel registration → issue credit
  - ✅ Rainout → automatic credits to all players
  - ✅ Checkout integration (apply/keep/donate)
- ✅ Roster builder with drag-drop
- ✅ Schedule builder with randomization
- ✅ Game status banner (always visible)
- ✅ Commerce integration (payments via Authorize.net)

## Development Environment

**Stack:**
- DDEV local development
- Drupal 11
- PHP 8.3
- MariaDB 10.6+

**Key Commands:**
```bash
ddev drush cr              # Clear cache
ddev drush updb -y         # Run database updates
ddev drush wd-del all -y   # Clear logs
ddev drush wd-show         # View logs
ddev drush cex -y          # Export config
ddev drush cim -y          # Import config
```

**Notification Testing:**
- Local emails → MailHog: https://ccsoccer-d11.ddev.site:8026
- SMS disabled in dev (checks environment)

## For Next Session

### Priority Tasks
1. Test complete checkout flow with credits end-to-end
2. Verify credits are properly deducted after order completion
3. Test rainout credit issuance from Game Status form
4. Test cancel registration credit issuance

### Phase 6 (Not Started)
- Player Credits Management Page (public-facing credit history)
- Manual adjustment capability for admins
- Filter by status
- Total balance display

### Nice to Have
- Checkout button alignment CSS fixes
- Hide Commerce green added to cart message when duplicate detected

---

## Credits System Architecture

### Credit Flow
1. **Earning Credits:**
   - Registration cancelled → CancelRegistrationForm issues credit
   - Game rained out → GameStatusForm issues credits to all players
   - Admin adjustment → (Phase 6)

2. **Using Credits:**
   - Checkout credits step shows balance and options
   - Player chooses: Apply / Keep / Donate
   - OrderCompleteSubscriber processes on order completion
   - Credits marked as used with FIFO (oldest first)

### Key Services
- `ccsoccer.credit_manager` - All credit operations
- `ccsoccer.order_complete_subscriber` - Processes credits on checkout

### Credit Storage
- All amounts stored in CENTS (integer) to avoid floating point issues
- Use CreditManagerService methods for conversion:
  - `dollarsToCents()` / `centsToDollars()`
  - `formatCentsAsDollars()` - Returns $X.XX format

## Collaboration Notes

**Working with Andrew:**
- Always `git pull` before `git push`
- Use SESSION_HANDOFF.md for detailed context
- View existing files before modifying (no complete file replacements)
- Comprehensive testing before commits

**Code Style:**
- Complete functions (not partial updates)
- Detailed logging for debugging
- Clear comments explaining business logic
- Follow Drupal coding standards
- Use update hooks for database/config changes (infrastructure as code)

---

## Git Workflow Reminder

```bash
git pull                          # Always pull first
git status                        # Check what changed
git add .                         # Stage changes
git commit -m "Descriptive msg"   # Commit
git push                          # Push to remote
```

**When conflicts occur:**
1. Review conflicted files
2. Manually merge keeping both changes where appropriate
3. Test thoroughly
4. Commit resolution
