# CC Soccer D11 - Session Handoff
**Date:** January 11, 2026  
**Last Updated:** Session End (Snapshot Restore Fix)

---

## COMPLETED THIS SESSION

### Snapshot Restore Bug Fix ✅

**Problem:** Clicking "Restore" on a snapshot showed success toast but reported "0 games updated". The schedule did not change.

**Root Cause:** The `restoreSnapshot()` method was matching games by `game_id`, which breaks when the schedule is regenerated after a snapshot is saved (new game entities have different IDs).

**Solution:** Changed to position-based matching:
- **Tournament:** Match by `time_slot` + `field` (unique grid position)
- **Season:** Match by `week_number` + `time_slot` + `field` (unique position across weeks)

**Files Modified:**
- `web/modules/custom/ccsoccer/src/Service/TournamentScheduleGeneratorService.php`
- `web/modules/custom/ccsoccer/src/Service/ScheduleGeneratorService.php`

**Function:** `restoreSnapshot()` - Updated in both files

### Snapshot Section UI Spacing Fix ✅

**Problem:** The arrow/chevron in the "Saved Snapshots" collapsible section was too close to the text.

**Solution:** Added `padding-left: 2rem` to the summary element to create proper spacing.

**File Modified:**
- `web/modules/custom/ccsoccer/css/schedule-builder.css`

- Insurance Report (player roster)
- Tournament Team Report (deposits and formation)
- Jersey Report (sizes/distribution)

**Migration (January-February):**
- Board decision on user pruning cutoff (2yr vs 3yr vs 5yr)

## ARCHITECTURE HIGHLIGHTS

### Snapshot System Architecture

```
User clicks "Save Snapshot"
    ↓
JavaScript sends POST to /snapshot/save
    ↓
Controller calls service->saveSnapshot()
    ↓
Service queries all games for entity
    ↓
Serializes game data (home_team, away_team, time_slot, field, etc.)
    ↓
Inserts into tournament_schedule_snapshot or season_schedule_snapshot table
    ↓
Returns success + updated snapshot list
    ↓
JavaScript refreshes snapshot table via refreshSnapshotList()
```

**Snapshot Restore Logic (Fixed):**
```
User clicks "Restore"
    ↓
Load snapshot data from database
    ↓
Build lookup by POSITION (not game_id):
  - Tournament: time_slot + field → "3_Field 2"
  - Season: week_number + time_slot + field → "5_2_Field 1"
    ↓
Load current games for entity
    ↓
For each current game:
  - Build position key from game's time_slot/field
  - Look up snapshot data by position
  - Update game if data differs
    ↓
Return count of games updated
```

**Database Tables:**
- `tournament_schedule_snapshot` - Tournament snapshots
- `season_schedule_snapshot` - Season snapshots

**Snapshot Data Structure:**
```php
[
  'id' => 123,
  'entity_id' => 24,
  'name' => '2026-01-11 18:32',
  'data' => serialize([
    [
      'game_id' => 456,           // Stored but NOT used for matching
      'home_team' => 12,
      'away_team' => 15,
      'time_slot' => 1,           // Used for position matching
      'field' => 'Field 1',       // Used for position matching
      'week_number' => 5,         // Season only - used for position matching
      // etc.
    ],
  ]),
  'created' => 1736624520,
  'uid' => 1,
]
```

### Tournament Schedule Algorithm

**Matchup Generation - Round-Robin Based:**
```
1. Generate round-robin rounds using circle method
   - Fix position 0, rotate all others
   - Creates n-1 rounds for n teams (even)
   - Each round has n/2 games, each team plays once

2. Score and sort rounds by total skill gap
   - Lower total gap = more skill-balanced round
   - Select best rounds first

3. Select rounds until each team has games_per_team games
   - Guarantees exact game count (hard constraint)
   - No possibility of dead ends

4. Fallback for odd teams (byes)
   - fillRemainingMatchups() uses constraint-aware greedy
   - Most-constrained-first prevents stuck states
```

### Tournament Group ID System

**Pattern:** UUID-based (matches Season groups)
```php
$group_id = \Drupal::service('uuid')->generate();
// Example: 550e8400-e29b-41d4-a716-446655440000
```

## TESTING NOTES

### Testing Snapshot Feature:
1. Navigate to `/admin/ccsoccer/tournament/{tournament}/schedule`
2. Generate a schedule
3. Click "💾 Save Snapshot" - verify toast appears and snapshot added to list
4. Make changes to the schedule (drag teams around)
5. Click "Restore" on the snapshot
6. **Verify:** Schedule reverts to saved state, toast shows correct game count
7. Click rename (✏️) - verify inline edit works
8. Click delete (🗑️) - verify confirmation and removal
9. Repeat on season schedule builder

### Testing Tournament Schedule Generation:
1. Navigate to `/admin/ccsoccer/tournament/{tournament}/schedule`
2. Click "Generate Schedule" button
3. **Verify:** All 14 teams have exactly 4 games (check Team Schedule Analysis table)
4. **Verify:** 28 total games created (14 teams × 4 games ÷ 2)
5. **Verify:** Empty cells are droppable (drag team to empty Field 4 slots)

### Testing Drag-Drop:
1. Drag a team from one cell to another (swap)
2. Drag a team to an empty cell (move)
3. Drag a team to workbench (temporary storage)
4. Drag from workbench back to grid
5. **Verify:** Rest warning toasts appear for back-to-back games

   - Include guidance: contact captain or tournament director

2. **Admin dashboard for unassigned players**
   - Route: `/admin/ccsoccer/tournament/{tournament}/unassigned`
   - Show players in awaiting and pool status
   - Interface to manually assign to teams

### Later (Phase 4):
3. Tournament public info page
4. Tournament teams list page
