# Major Implementation Complete: Account/Character System

**Date:** November 9, 2025  
**Status:** ✅ BACKEND COMPLETE - Frontend Pending  

---

## 🎉 What Was Implemented

### 1. Database Migration ✅
- **New Tables Created:**
  - `accounts` - Authentication and account management
  - `characters` - Game characters (1-10 per account)
  
- **Migration Results:**
  - ✅ 5 existing players migrated to accounts + characters
  - ✅ All foreign keys updated (inventory, combats, equipment, etc.)
  - ✅ Old `players` table dropped
  - ✅ Indexes optimized for new schema

### 2. Authentication System Refactor ✅
- **Email-Based Auth:** Login/register now use email instead of username
- **JWT Tokens Updated:** Include both `account_id` and `character_id`
- **Character Selection Required:** Must select character after login

**New Endpoints:**
```
POST /api/auth/register - Register with email
POST /api/auth/login - Login with email
GET /api/characters - List all characters for account
POST /api/characters - Create new character (with stat allocation)
POST /api/characters/select - Select character to play
DELETE /api/characters/{id} - Delete character
```

### 3. Character System Features ✅
- **Multi-Character Support:** 1 character for free, 10 for premium
- **Character Creation:**
  - Unique name requirement (validated)
  - 20 stat points to distribute (strength/agility/endurance/intellect)
  - Calculated HP/stamina based on endurance
  - Avatar support (placeholder for now)
  
- **Premium Restrictions Enforced:**
  - Free accounts: 1 character maximum
  - Premium accounts: 10 characters maximum

### 4. Database Schema Changes ✅

**Accounts Table:**
```sql
- id (PRIMARY KEY)
- email (UNIQUE, NOT NULL)
- password_hash
- steam_id (UNIQUE, for future Steam integration)
- account_type ('web' or 'steam')
- premium_expires_at (NULL = free, timestamp = premium end)
- created_at, last_login_at
```

**Characters Table:**
```sql
- id (PRIMARY KEY)
- account_id (FK to accounts)
- name (UNIQUE, character name)
- avatar_data (JSON for avatar customization)
- level, xp, hp, max_hp, stamina, max_stamina
- strength, agility, endurance, intellect, unspent_points
- location_id, is_dead, last_movement_time
- created_at, last_played_at
```

**Updated Foreign Keys:**
- `inventory.character_id` (was player_id)
- `active_combats.character_id` (was player_id)
- `pvp_combats.attacker_character_id` & `defender_character_id`
- `equipment_slots.character_id`
- `player_status_effects.character_id`
- `player_statistics.character_id`
