-
-### Storage Backends
-
-#### Metadata Database (SQLite)
-```sql
--- File metadata
-CREATE TABLE files (
-    hash TEXT PRIMARY KEY,
-    filename TEXT,
-    size INTEGER,
-    storage_type TEXT, -- 'blob' or 'chunked'
-    created_at DATETIME,
-    user_id TEXT
-);
-
--- Torrent information
-CREATE TABLE torrents (
-    info_hash TEXT PRIMARY KEY,
-    file_hash TEXT,
-    piece_length INTEGER,
-    pieces_count INTEGER,
-    magnet_link TEXT,
-    FOREIGN KEY(file_hash) REFERENCES files(hash)
-);
-
--- Chunk mapping for large files
-CREATE TABLE chunks (
-    file_hash TEXT,
-    chunk_index INTEGER,
-    chunk_hash TEXT,
-    chunk_size INTEGER,
-    PRIMARY KEY(file_hash, chunk_index)
-);
-
--- Transcoding job tracking
-CREATE TABLE transcoding_status (
-    file_hash TEXT PRIMARY KEY,
-    status TEXT NOT NULL,
-    error_message TEXT,
-    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
-    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
-);
-```
-
-#### Blob Storage
-- Direct file storage in `./data/blobs/`
-- SHA-256 content addressing
-- Efficient for small files and frequently accessed content
-- No P2P overhead - immediate availability
-
-#### Chunk Storage
-- Large files split into 2MB pieces in `./data/chunks/`
-- BitTorrent-compatible piece structure
-- Enables parallel downloads and partial file access
-- Each chunk independently content-addressed
-
-#### Transcoded Storage
-- Processed video files stored in `./data/transcoded/`
-- Organized by original file hash subdirectories
-- H.264/AAC MP4 format for universal web compatibility
-- Smart serving prioritizes transcoded versions when available
-
-### Caching System
-
-#### LRU Piece Cache
-```go
-type PieceCache struct {
-    cache map[string]*CacheEntry
-    lru   *list.List
-    mutex sync.RWMutex
-    maxSize int64
-    currentSize int64
-}
-
-type CacheEntry struct {
-    Key string
-    Data []byte
-    Size int64
-    AccessTime time.Time
-    Element *list.Element
-}
-```
-
-**Features**:
-- Configurable cache size limits
-- Least Recently Used eviction
-- Concurrent access with read-write locks
-- Cache hit ratio tracking and optimization
-
-## Video Transcoding System
-
-### Architecture Overview
-
-The transcoding system provides automatic video conversion for web compatibility:
-
-```go
-type TranscodingEngine struct {
-    // Core Components
-    Transcoder    *Transcoder     // FFmpeg integration
-    Manager       *Manager        // Job coordination
-    WorkerPool    chan Job        // Background processing
-    Database      *sql.DB         // Status tracking
-    
-    // Configuration
-    ConcurrentJobs int            // Parallel workers
-    WorkDirectory  string         // Processing workspace
-    QualityProfiles []Quality     // Output formats
-}
-```
-
-### Processing Pipeline
-
-1. **Upload Detection**: Video files automatically identified during upload
-2. **Queue Decision**: Files ≥50MB queued for transcoding with priority based on size
-3. **File Reconstruction**: Chunked torrents reassembled into temporary files
-4. **FFmpeg Processing**: H.264/AAC conversion with web optimization flags
-5. **Smart Serving**: Transcoded versions served when ready, originals as fallback
-
-### Transcoding Manager
-
-```go
-func (tm *Manager) QueueVideoForTranscoding(fileHash, fileName, filePath string, fileSize int64) {
-    // Check if already processed
-    if tm.HasTranscodedVersion(fileHash) {
-        return
-    }
-    
-    // Analyze file format
-    needsTranscoding, err := tm.transcoder.NeedsTranscoding(filePath)
-    if !needsTranscoding {
-        tm.markAsWebCompatible(fileHash)
-        return
-    }
-    
-    // Create prioritized job
-    job := Job{
-        ID:        fmt.Sprintf("transcode_%s", fileHash),
-        InputPath: filePath,
-        OutputDir: filepath.Join(tm.transcoder.workDir, fileHash),
-        Priority:  tm.calculatePriority(fileSize),
-        Callback:  tm.jobCompletionHandler,
-    }
-    
-    tm.transcoder.SubmitJob(job)
-    tm.markTranscodingQueued(fileHash)
-}
-```
-
-### Smart Priority System
-
-- **High Priority** (8): Files < 500MB for faster user feedback
-- **Medium Priority** (5): Standard processing queue
-- **Low Priority** (2): Files > 5GB to prevent resource monopolization
-
-### Status API Integration
-
-Users can track transcoding progress via authenticated endpoints:
-- `/api/users/me/files/{hash}/transcoding-status` - Real-time status and progress
-- Response includes job status, progress percentage, and transcoded file availability
-
-## P2P Integration & Coordination
-
-### Unified Peer Discovery
-
-The P2P coordinator aggregates peers from multiple sources:
-
-1. **BitTorrent Tracker**: Authoritative peer list from announces
-2. **DHT Network**: Distributed peer discovery across the network
-3. **WebSeed**: Gateway itself as a reliable seed source
-
-### Smart Peer Ranking Algorithm
-
-```go
-func (pr *PeerRanker) RankPeers(peers []PeerInfo, clientLocation *Location) []RankedPeer {
-    var ranked []RankedPeer
-    
-    for _, peer := range peers {
-        score := pr.calculatePeerScore(peer, clientLocation)
-        ranked = append(ranked, RankedPeer{
-            Peer: peer,
-            Score: score,
-            Reason: pr.getScoreReason(peer, clientLocation),
-        })
-    }
-    
-    // Sort by score (highest first)
-    sort.Slice(ranked, func(i, j int) bool {
-        return ranked[i].Score > ranked[j].Score
-    })
-    
-    return ranked
-}
-```
-
-**Scoring Factors**:
-- **Geographic Proximity** (30%): Distance-based scoring
-- **Source Reliability** (25%): Tracker > DHT > WebSeed fallback
-- **Historical Performance** (20%): Past connection success rates
-- **Load Balancing** (15%): Distribute load across available peers
-- **Freshness** (10%): Recently seen peers preferred
-
-### Health Monitoring System
-
-#### Component Health Scoring
-```go
-type HealthStatus struct {
-    IsHealthy     bool      `json:"is_healthy"`
-    Score         int       `json:"score"`          // 0-100
-    Issues        []string  `json:"issues"`
-    LastChecked   time.Time `json:"last_checked"`
-    ResponseTime  int64     `json:"response_time"`  // milliseconds
-    Details       map[string]interface{} `json:"details"`
-}
-```
-
-**Weighted Health Calculation**:
-- WebSeed: 40% (most critical for availability)
-- Tracker: 35% (important for peer discovery)
-- DHT: 25% (supplemental peer source)
-
-#### Automatic Alerting
-- Health scores below configurable threshold trigger alerts
-- Multiple alert mechanisms (logs, callbacks, future integrations)
-- Component-specific and overall system health monitoring
-
-## WebSeed Implementation (BEP-19)
-
-### Standards Compliance
-
-The WebSeed implementation follows BEP-19 specification:
-
-- **URL-based seeding**: BitTorrent clients can fetch pieces via HTTP
-- **Range request support**: Efficient partial file downloads
-- **Piece boundary alignment**: Proper handling of piece boundaries
-- **Error handling**: Appropriate HTTP status codes for BitTorrent clients
-
-### Advanced Features
-
-#### Concurrent Request Optimization
-```go
-type ConcurrentRequestTracker struct {
-    activeRequests map[string]*RequestInfo
-    mutex          sync.RWMutex
-    maxConcurrent  int
-}
-```
-
-- Prevents duplicate piece loads
-- Manages concurrent request limits
-- Request deduplication and waiting
-
-#### Client-Specific Optimizations
-```go
-func (h *Handler) detectClient(userAgent string) ClientType {
-    switch {
-    case strings.Contains(userAgent, "qbittorrent"):
-        return ClientQBittorrent
-    case strings.Contains(userAgent, "transmission"):
-        return ClientTransmission
-    case strings.Contains(userAgent, "webtorrent"):
-        return ClientWebTorrent
-    // ... additional client detection
-    }
-}
-```
-
-**Per-Client Optimizations**:
-- **qBittorrent**: Standard intervals, no special handling needed
-- **Transmission**: Prefers shorter announce intervals (≤30 min)
-- **WebTorrent**: Short intervals for web compatibility (≤5 min)
-- **uTorrent**: Minimum interval enforcement to prevent spam
-
-## Nostr Integration
-
-### Content Announcements
-
-When files are uploaded, they're announced to configured Nostr relays:
-
-```go
-func (g *Gateway) announceToNostr(fileInfo *FileInfo, torrentInfo *TorrentInfo) error {
-    event := nostr.Event{
-        Kind:      2003, // NIP-35 torrent announcement kind
-        Content:   fmt.Sprintf("New torrent: %s", fileInfo.Filename),
-        CreatedAt: time.Now(),
-        Tags: []nostr.Tag{
-            {"magnet", torrentInfo.MagnetLink},
-            {"size", fmt.Sprintf("%d", fileInfo.Size)},
-            {"name", fileInfo.Filename},
-            {"webseed", g.getWebSeedURL(fileInfo.Hash)},
-        },
-    }
-    
-    return g.nostrClient.PublishEvent(event)
-}
-```
-
-### Decentralized Discovery
-
-- Content announced to multiple Nostr relays for redundancy
-- Other nodes can discover content via Nostr event subscriptions
-- Enables fully decentralized content network
-- No central authority or single point of failure
-
-## Performance Optimizations
-
-### Concurrent Processing
-
-#### Parallel Piece Loading
-```go
-func (ws *WebSeedHandler) loadPieces(pieces []PieceRequest) error {
-    const maxConcurrency = 10
-    semaphore := make(chan struct{}, maxConcurrency)
-    var wg sync.WaitGroup
-    
-    for _, piece := range pieces {
-        wg.Add(1)
-        go func(p PieceRequest) {
-            defer wg.Done()
-            semaphore <- struct{}{}        // Acquire
-            defer func() { <-semaphore }() // Release
-            
-            ws.loadSinglePiece(p)
-        }(piece)
-    }
-    
-    wg.Wait()
-    return nil
-}
-```
-
-#### Connection Pooling
-- HTTP client connection reuse
-- Database connection pooling
-- BitTorrent connection management
-- Resource cleanup and lifecycle management
-
-## Monitoring & Observability
-
-### Comprehensive Statistics
