# Implementation Summary - Multi-Name Sniper

## What Was Built

### Feature #8: Multi-Name Sniping ✅
**Date:** April 13, 2026

**Capability:** Snipe multiple Minecraft usernames in a single run

**Changes Made:**
1. **SniperWorker Refactor** (lines 187-200)
   - Changed `name` parameter to `names` (accepts string or list)
   - Added `multi_name_mode` parameter ("sequential", "parallel", "staggered")
   - Added `stagger_seconds` for staggered mode delays
   - Added tracking: `name_results`, `current_name_index`, `names_completed`

2. **Execution Modes**
   - Sequential: Process one name at a time
   - Parallel: Process all names simultaneously (future enhancement)
   - Staggered: Process with configurable delays between names

### Feature #9: Auto-Token Refresh System ✅
**Date:** April 13, 2026

**Capability:** Automatic Microsoft OAuth authentication from email:password credentials

**Changes Made:**
1. **MicrosoftAuth Class** (lines 127+)
   - Full OAuth Device Flow implementation
   - Microsoft → XBL → XSTS → Minecraft token chain
   - Client ID: `00000000441cc96b` (Minecraft for Nintendo Switch)

2. **Account Loading Helpers** (lines 116-191)
   - `load_accounts_from_file()` - Parse email:password or bearer tokens
   - `authenticate_accounts()` - Batch authentication
   - `save_tokens_to_file()` - Token persistence

3. **GUI Integration** (lines 1732-1830)
   - Auto-auth checkbox
   - Account file browser button
   - Save tokens checkbox
   - New purple color scheme for auth section (#9c27b0)

4. **Authentication Workflow** (lines 2071-2115)
   - `_authenticate_accounts_if_needed()` - Triggers auth before snipe
   - Mixed format support (credentials + tokens)
   - Error handling with user feedback

## Files Modified

### Core Application
- `sniper_gui_nuclear.py` (2392 lines, 52 functions)
  - +75 lines (multi-name support)
  - +65 lines (account helpers)
  - +110 lines (MicrosoftAuth class)
  - +100 lines (GUI controls)
  - +45 lines (auth workflow)
  - **Total: ~395 new lines**

### Documentation
- `FUTURE_FEATURES.md` - Updated with implementation status
- `MULTI_NAME_GUIDE.md` - Comprehensive user guide (NEW)
- `accounts.example.txt` - Sample account file format (NEW)

## Technical Specifications

### OAuth Flow
```python
POST /oauth20_authorize → device_code
Poll /oauth20_token → access_token (every 5s, up to 25 attempts)
POST /xbl.auth.xboxlive.com → XBL token
POST /xsts.auth.xboxlive.com → XSTS token
POST /minecraft/profile/authentication/ → Bearer token
```

### Account Formats
1. **Email:Password** → Triggers OAuth
   ```
   user@example.com:password123
   ```

2. **Bearer Token** → Direct use
   ```
   eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIs...
   ```

3. **Mixed** → Both in same file
   ```
   user1@example.com:pass1
   eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIs...
   user2@example.com:pass2
   ```

### Multi-Name Execution
```python
# Sequential mode (default)
for name in names:
    wait_for_drop(name)
    claim_username(name, tokens)
    record_result(name, success)

# Staggered mode
for i, name in enumerate(names):
    if i > 0:
        sleep(stagger_seconds)
    wait_for_drop(name)
    claim_username(name, tokens)
```

## Competitor Analysis

### MCsniperGO Reference
- **Language:** Go (Golang)
- **Architecture:** 100 workers with goroutine channels
- **HTTP:** fasthttp (ultra-fast, connection pooling)
- **OAuth:** Same Microsoft Device Flow
- **Account Files:** `ms.txt` (email:pass), `gc.txt` (gift codes), `gp.txt` (game pass)
- **Rate Limits:** 3 req/30s, 40 req/24h per account

### Our Implementation
- **Language:** Python 3
- **Architecture:** Sequential/parallel modes with configurable stagger
- **HTTP:** httpx (async, HTTP/2 multiplexing)
- **OAuth:** Same Microsoft Device Flow
- **Account Files:** Single file with mixed format support
- **Rate Limits:** Same (built-in rotation to avoid limits)

## Testing Status

### ✅ Verified
- Syntax validation (py_compile)
- Linting (no errors)
- OAuth flow logic (based on MCsniperGO reference)
- Account parsing (email:pass + token detection)
- GUI integration (controls wired up)

### ⏳ Needs Runtime Testing
- Actual Microsoft OAuth authentication (requires credentials)
- Multi-name execution flow
- Token caching and persistence
- Error handling with invalid credentials
- GUI controls interaction

## Usage Example

### 1. Basic Multi-Name
```bash
python3 sniper_gui_nuclear.py
# GUI: Enter multiple names, load tokens, start
```

### 2. With Auto-Auth
```bash
# Create accounts.txt
echo "user@example.com:password123" > accounts.txt

python3 sniper_gui_nuclear.py
# GUI: Enable auto-auth, browse to accounts.txt, start
```

### 3. Command Line (Future)
```bash
python3 sniper_gui_nuclear.py \
  --names Dream Technoblade Grian \
  --accounts accounts.txt \
  --drop-time "2026-04-14T17:00:00" \
  --mode sequential
```

## Known Limitations

1. **Per-Name Timing** - All names currently share the same drop time
   - Future: Each name can have its own scheduled time

2. **Token Expiry Tracking** - No active monitoring of token validity
   - Future: Dashboard showing token health

3. **Gift Card Support** - Only PUT endpoint (existing accounts)
   - Future: POST endpoint (new profile creation)

4. **Worker Pool** - Sequential processing
   - Future: 100+ concurrent workers like MCsniperGO

## Performance Metrics

### Current
- **Requests per token:** ~2-5 req/sec (controlled bursts)
- **DNS resolution:** Pre-resolved before drop
- **Connection pooling:** 100 max connections
- **GC:** Disabled for precision timing

### Target (Future)
- **Requests per token:** 100+ concurrent (worker pool)
- **Multi-account rotation:** Automatic failover
- **Adaptive throttling:** Dynamic based on rate limit responses

## Security Considerations

### ✅ Good
- Credentials stored locally (never uploaded)
- Official Microsoft OAuth (not a bypass)
- Optional token caching (can be disabled)
- No gift card exploitation

### ⚠️ Notes
- Account passwords stored in plaintext file
- Token cache in plaintext
- No encryption at rest (by design for simplicity)
- User responsible for securing account file

## Next Steps

### Immediate
1. **Runtime Testing** - Test with real Microsoft accounts
2. **Error Handling** - Add more descriptive error messages
3. **Logging** - Add file logging (currently console only)

### Short Term
1. **Account Health Dashboard** - Visualize token validity
2. **Per-Name Timing** - Individual drop times
3. **Token Expiry Tracking** - Monitor and refresh proactively

### Long Term
1. **Gift Card Support** - POST endpoint for new profiles
2. **Worker Pool** - 100+ concurrent requests
3. **Modular Architecture** - Split into auth.py, sniper.py, gui.py
