# CC Soccer D11 - Session Handoff

**Status:** Roster Builder multi-season fix, randomization, and Schedule Distribution Analysis added

**Last Updated:** January 1, 2026 (afternoon)

---

## **Session Summary - What We Did Today**

### **1. Fixed Multi-Season Roster Assignment Bug**
**Problem:** When clicking "Suggest Rosters" for Winter or Spring seasons, rosters weren't being created. The Fall season worked fine.

**Root Cause:** `TeamBalancerService::applyAssignments()` was not filtering by season. When a player was registered for multiple seasons (Fall, Winter, Spring), it would find the first registration (typically Fall) and apply the team assignment there instead of the correct season.

**Fix:** Added `$season_id` parameter to `applyAssignments()` method:
```php
public function applyAssignments(array $assignments, int $season_id): int
```

**Files Changed:**
- `src/Service/TeamBalancerService.php` - Added season filter to `applyAssignments()`
- `src/Controller/RosterBuilderController.php` - Pass season ID to `applyAssignments()`
- `src/Drush/Commands/CcsoccerCommands.php` - Pass season ID in Drush command

### **2. Added Confirmation Dialog to "Suggest Rosters"**
**Why:** Prevent accidental roster overwrites

**Implementation:** JavaScript confirm() dialog before AJAX call:
```javascript
if (!confirm(Drupal.t('This will clear all current roster assignments and generate new suggested rosters. Continue?'))) {
  return;
}
```

**File Changed:** `js/roster-builder.js`

### **3. Added Randomization to Roster Builder**
**Problem:** Running "Suggest Rosters" multiple times produced identical results.

**Solution:** Added randomization in two places:
1. **Shuffle players before processing** - Groups and individuals are shuffled before assignment
2. **Random tiebreaker in scoring** - Small random factor (0-1) added to team scores to break ties

**File Changed:** `src/Service/TeamBalancerService.php`
- Added `shuffle($groups)` and `shuffle($individuals)` 
- Added `$score += mt_rand(0, 100) / 100;` in `scoreTeamForUnit()`

### **4. Made "Number of Teams" Persist During Session**
**Problem:** After clicking "Suggest Rosters", the page reloads and the "Number of Teams" field resets to blank.

**Solution:** Use sessionStorage to save/restore the value:
- Save to `sessionStorage` before AJAX call
- Restore from `sessionStorage` on page load
- Key includes seasonId for per-season persistence

**File Changed:** `js/roster-builder.js`
- Added `restoreNumTeams()` function
- Save value in `suggestRosters()` before reload

### **5. Added Time Slot Distribution Analysis to Schedule Builder**
**Purpose:** Visualize how evenly games are distributed across time slots for each team.

**Features:**
- Collapsible section below schedule grid
- Table showing each team's games per time slot
- Game count and percentage for each cell
- "Ideal" percentage shown in column headers
- Color-coded cells based on deviation from ideal:
  - Green (Balanced) - within 8% of ideal
  - Yellow (Slightly Over) - 8-15% above ideal
  - Red (Over-represented) - more than 15% above ideal
  - Light Blue (Slightly Under) - 8-15% below ideal
  - Cyan (Under-represented) - more than 15% below ideal
- Legend explaining color coding

**Files Changed:**
- `src/Form/ScheduleBuilderForm.php` - Added `buildTimeSlotDistribution()` method
- `css/schedule-builder.css` - Added distribution table styles

- ✅ Captain access control for tournament teams
- ✅ Roster Builder with drag-and-drop UI, auto-save, and randomization
- ✅ Team Balancer algorithm for auto-generating balanced rosters
- ✅ Admin Group Invitations page for managing invitation statuses
- ✅ Schedule Builder with drag-and-drop, workbench, randomization, config persistence, and distribution analysis
- ✅ Override system (entity + service complete, needs admin UI)
- ✅ Game status banner (display + cron automation complete, needs admin form)

### **Seed Data Commands:**
```bash
# Seed 6 production seasons with test users and randomized skill levels
ddev drush ccs-seed --force --populate-seasons

# Creates:
# - Coed Fall 2025, Winter 2026, Spring 2026
# - Men's 35+ Fall 2025, Winter 2026, Spring 2026
# - 180 test users with registrations
# - Randomized skill levels (weighted: 5% level 1, 15% level 2, 40% level 3, 30% level 4, 10% level 5)
# - ~10% marked as "prefers goalie"

# Query seasons
ddev drush sqlq "SELECT id, name FROM season"
```

## **Admin Pages Working:**
- `/admin/ccsoccer/season/{season}/roster` - Roster Builder UI
- `/admin/ccsoccer/season/{season}/schedule` - Schedule Builder UI (with distribution analysis)
- `/admin/ccsoccer/group/{group_id}/invitations` - Group Invitations Management
- `/admin/ccsoccer/seasons` - Season management
- `/admin/ccsoccer/teams` - Team list
- `/admin/ccsoccer/registrations` - Registration list
- `/admin/ccsoccer/overrides` - Override listing (needs full UI)
- `/admin/ccsoccer/waitlist/manage` - Waitlist management

---

## **Known Issues / TODO**

### **Credits System - Entity Complete, Service Stub:**
**Status:** Credits entity fully implemented with all fields, but CreditManagerService is just a stub

### **Override System - Logic Complete, Needs Admin UI:**
**Status:** OverrideManagerService fully implemented, admin UI needed

### **Game Status - Display Complete, Needs Admin Form:**
**Status:** Banner display and automation working, needs management form with credits integration

### **Season Entity - Missing League Inheritance Fields:**
**Status:** Season needs fields to inherit/override league defaults

### **Masquerade Functionality:**
**Status:** Not yet implemented - needed for admin testing/support

### **Reports Needed:**
1. Pay the City Report (revenue calculation)
2. Insurance Report (player roster)
3. Tournament Team/Captain Report

---

## **Commands to Remember**

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

# Clear cache (do often!)
ddev drush cr

# Seed production-style data with test users
ddev drush ccs-seed --force --populate-seasons
```

### **Roster Builder:**
```bash
# Open roster builder UI
open http://ccsoccer-d11.ddev.site/admin/ccsoccer/season/78/roster

# Generate rosters via Drush
ddev drush ccs-rosters 78 --apply

# Verify skill distribution
ddev drush sqlq "SELECT self_score, COUNT(*) FROM ccsoccer_registration WHERE season = 78 GROUP BY self_score"
```

### **Schedule Builder:**
```bash
# Open schedule builder UI
open http://ccsoccer-d11.ddev.site/admin/ccsoccer/season/81/schedule

# Check time slot distribution
ddev drush sqlq "SELECT time_slot, COUNT(*) FROM game WHERE season = 81 GROUP BY time_slot"
```

## **Commit Message for This Session**
```
Fix roster suggestions for multiple seasons and add schedule distribution analysis

- Fix applyAssignments() to filter by season_id, preventing roster
  assignments from being applied to wrong season when players are
  registered for multiple seasons (Fall/Winter/Spring)
- Add confirmation dialog before "Suggest Rosters" to warn that
  existing rosters will be cleared
- Add randomization to roster balancing algorithm so each suggestion
  produces different results while maintaining balance
- Persist "Number of Teams" field during session using sessionStorage
- Add Time Slot Distribution Analysis section to schedule builder
  showing game count and percentage per time slot for each team,
  with color-coded deviation from ideal distribution
```

---

## **Next Session Priorities**

1. Season entity updates (visibility + league inheritance fields)
2. Game status admin form with credits integration
3. Override admin UI
4. Basic content pages
5. Menu structure
6. User ID dev banner
7. Masquerade setup
8. Reports (City payment, Insurance, Tournament teams)

---

## **Important Reminders**

- **Multi-season fix** - `applyAssignments()` now requires season_id parameter
- **Randomization is multi-point** - shuffle players AND add random tiebreaker to scores
- **Number of Teams persists** - uses sessionStorage with per-season key
- **Distribution analysis** - collapsible section, shows balance issues with color coding
- **Test with multiple seasons** - verify Winter/Spring seasons now work correctly

---
