## **Major Accomplishments**

### **Custom Registration Entity - Complete** (Dec 18, 2024)

**ARCHITECTURAL DECISION:** Built custom Registration entity instead of extending contrib Registration module.

**Why Custom:**
- Contrib Registration designed for "event attachment" (host entity pattern: registrations attached to nodes/events)
- Required `entity_type_id` and `entity_id` fields we don't need
- Our needs: Direct `season` OR `tournament` entity references (XOR pattern)
- Cleaner queries: `WHERE season=X` not `WHERE entity_type_id='season' AND entity_id=X`
- Full control over 25+ custom fields and complex business logic
- No fighting module assumptions about workflows

**Result:**
- ✅ Table `ccsoccer_registration` created with all fields
- ✅ Entity tested and working (can create/edit via admin UI)
- ✅ Removed `drupal/registration` and `drupal/commerce_registration` dependencies
- ✅ Added to admin menu at `/admin/ccsoccer/registrations`
- ✅ All 25+ fields implemented (jersey, groups, waitlist, credits, tournament deposits)
- ⏳ Next: Custom Commerce integration hooks (~100 lines of code)

**Commerce Integration Plan:**
- Write custom `hook_commerce_checkout_complete()` to create registrations
- Write custom `hook_commerce_order_paid_in_full()` to update status
- Build custom checkout panes for jersey, skill, goalie, groups, team selection
- Handle season vs tournament logic in our code
- ~100 lines total for full control over registration workflow

### **All 7 Core Entities Complete** (Dec 16-18, 2024)

**Entity Implementation Status:**

1. **League** - Configuration entity for league types (Coed, Men's, etc.)
   - Fields: name, type, team sizes, price, day of week, time slots, fields
   - Used by: Season entities

2. **Season** - Regular weekly league play
   - Fields: league ref, dates, pricing, capacity, reserved spots, skip days
   - Supports: Waitlist, overrides, credits, groups, jersey management
   - Admin tools: Roster builder, schedule generator

3. **Tournament** - Standalone one-day events  
   - Fields: dates, max_teams, deposit, pricing, age/gender rules, format
   - Captain-led: Deposit system, team formation, no waitlist/credits
   - Open to all players (not just season regulars)

4. **Team** - Generated (seasons) or captain-formed (tournaments)
   - XOR: season OR tournament (not both)
   - Fields: name, players, captain, colors, calculated stats
   - Balancing: skill, age, gender, goalie distribution

5. **Game** - Scheduled matches
   - XOR: season OR tournament (not both)
   - Fields: date, time, teams, field, time_slot, status
   - Supports: Cancellations, credits, referee assignment

6. **Credits** - Audit trail for season cancellations/rainouts
   - Fields: user, amount, type, source, expires, status
   - Formula: (paid / total_games) * remaining * 0.75
   - Tournaments: Do NOT use credits

7. **Registration** - CUSTOM entity (not contrib)
   - XOR: season OR tournament (not both)
   - Season fields: jersey, goalie, groups, waitlist, override, credits
   - Tournament fields: deposit, captain, team selection
   - Common: waiver, status, cancellation tracking

**Architecture Patterns:**
- XOR validation: Teams and Games belong to season OR tournament (enforced)
- Credits only for seasons (not tournaments)
- Groups are logical (group_id field, not separate entity)
- User fields extended (not separate Player entity)

## **Module Rename: cc_soccer → ccsoccer** (Dec 17, 2024)

**Why:** Cleaner machine name, easier to type, more professional

**What Changed:**
- All file names updated
- All PHP namespaces: `Drupal\cc_soccer\` → `Drupal\ccsoccer\`
- All routes: `/admin/cc-soccer/` → `/admin/ccsoccer/`
- All permissions: `administer cc soccer` → `administer ccsoccer`
- All services: `cc_soccer.service` → `ccsoccer.service`

**Result:** Clean, working module with proper naming convention

---

## **Architecture Decisions Made**

See **ARCHITECTURE_DECISIONS.md** for full decision log. Key decisions:

### **1. Custom Registration Entity** (Dec 18, 2024)
**Decision:** Build custom entity instead of extending contrib Registration module  
**Why:** Contrib designed for different use case (event attachment pattern)  
**Impact:** Clean data model, full control, ~100 lines of Commerce integration code

### **2. Tournament as Separate Entity** (Dec 17, 2024)
**Decision:** Separate entity, not a Season type  
**Why:** Fundamentally different workflows (capacity, team formation, no waitlist/credits)  
**Impact:** Cleaner queries, no conditional logic everywhere

### **3. Extend User Entity** (Dec 16, 2024)
**Decision:** Add fields to core User entity, not create Player entity  
**Why:** Player attributes belong to person, not role  
**Impact:** Simpler data model, roles handle permissions

### **4. Groups as Logical Collections** (Dec 17, 2024)
**Decision:** `group_id` field on Registration, not separate Group entity  
**Why:** Simple queries, temporary data structure  
**Impact:** Easy to implement, no extra entity management

## **Commands to Remember**

### **Daily Development:**
```bash
# Start DDEV
ddev start

# Clear cache (do this often!)
ddev drush cr

# Check module status
ddev drush pml | grep ccsoccer

# Database access
ddev drush sql-cli

# Git workflow
git status
git add -A
git commit -m "message"
git push origin main
```

### **Entity Testing:**
```bash
# Create test registration
ddev drush php:eval "
\$reg = \Drupal::entityTypeManager()
  ->getStorage('ccsoccer_registration')
  ->create([
    'registration_type' => 'season',
    'season' => 1,
    'player' => 1,
    'status' => 'pending',
    'waiver_signed' => TRUE,
  ]);
\$reg->save();
print 'Created: ' . \$reg->id();
"

# Check entity definition
ddev drush ev "print_r(\Drupal::entityTypeManager()->getDefinition('ccsoccer_registration'));"

# Update entity schema
ddev drush ev "\Drupal::entityDefinitionUpdateManager()->installEntityType(\Drupal::entityTypeManager()->getDefinition('ccsoccer_registration'));"
```

## **Key Contacts / Collaboration**

**Team:**
- Caleb (developer, this project)
- Andrew (abmeade@hotmail.com, collaborator)

**Tools:**
- Git: GitHub repo (pushed regularly)
- DDEV: Local development environment
- InMotion Hosting: Production (future)

**Current Focus:**
- Building in DDEV local environment
- All work in LOCAL environment
- TEST and LIVE environments to be set up later

---

## **Reference Context**

**D7 to D11 Migration:**
- Legacy D7 system exists and is running
- Was architecturally compromised (nodes instead of entities)
- D11 rebuild is ground-up with proper architecture

**CC Soccer Operations:**
- Coed league: Tuesdays, ~18 teams
- Men's league: Thursdays, ~6 teams
- Tournaments: Standalone events, captain-led
- Complex waitlist with 2-day override windows
- Credits system: 75% of remaining games value
- Group invitations: Friends register together
- Jersey management: Auto-add on first registration

---

## **Conversation Continuity**

**To pick up in next chat, just say:**
> "Continue with ccsoccer - all 7 entities are done, ready for Commerce integration"

**Claude has tools to:**
- Search past conversations
- Retrieve recent chats
- Access project files
- Read documentation

**You don't need to:**
- Copy/paste documentation
- Re-explain architecture
- Repeat what we've done

**Just start fresh - context will load automatically!**

---

## **Notes & Reminders**

- **Always `ddev drush cr` after code changes**
- **Commit to git frequently** (working states)
- **Test incrementally** (don't build too much before testing)
- **Entity fields need cache clear to be recognized**
- **Registration is CUSTOM entity** (not contrib)
- **Commerce integration is next** (~100 lines of clean code)
- **All 7 core entities complete** - solid foundation built

---

**End of Handoff - Ready for Commerce Integration!**

**Major Milestone Achieved:** Complete custom entity architecture with Registration as custom entity

**Next Big Step:** Commerce checkout integration for actual registration workflow
