fix(detection): fix SNI detection in TLS detector

- Created ts/detection module for unified protocol detection
- Implemented TLS and HTTP detectors with fragmentation support
- Moved TLS detection logic from existing code to centralized module
- Updated RouteConnectionHandler to use ProtocolDetector for both TLS and HTTP
- Refactored ACME HTTP parsing to use detection module
- Added comprehensive tests for detection functionality
- Eliminated duplicate protocol detection code across codebase

This centralizes all non-destructive protocol detection into a single module,
improving code organization and reducing duplication between ACME and routing.

+# SmartProxy Byte Counting Audit Report
+
+## Executive Summary
+
+After a comprehensive audit of the SmartProxy codebase, I can confirm that **byte counting is implemented correctly** with no instances of double counting. Each byte transferred through the proxy is counted exactly once in each direction.
+
+## Byte Counting Implementation
+
+### 1. Core Tracking Mechanisms
+
+SmartProxy uses two complementary tracking systems:
+
+1. **Connection Records** (`IConnectionRecord`):
+   - `bytesReceived`: Total bytes received from client
+   - `bytesSent`: Total bytes sent to client
+
+2. **MetricsCollector**:
+   - Global throughput tracking via `ThroughputTracker`
+   - Per-connection byte tracking for route/IP metrics
+   - Called via `recordBytes(connectionId, bytesIn, bytesOut)`
+
+### 2. Where Bytes Are Counted
+
+Bytes are counted in only two files:
+
+#### a) `route-connection-handler.ts`
+- **Line 351**: TLS alert bytes when no SNI is provided
+- **Lines 1286-1301**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+#### b) `http-proxy-bridge.ts`  
+- **Line 127**: Initial TLS chunk for HttpProxy connections
+- **Lines 142-154**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+## Connection Flow Analysis
+
+### 1. Direct TCP Connection (No TLS)
+
+```
+Client → SmartProxy → Target Server
+```
+
+1. Connection arrives at `RouteConnectionHandler.handleConnection()`
+2. For non-TLS ports, immediately routes via `routeConnection()`
+3. `setupDirectConnection()` creates target connection
+4. `setupBidirectionalForwarding()` handles all data transfer:
+   - `onClientData`: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+   - `onServerData`: `bytesSent += chunk.length` + `recordBytes(0, chunk.length)`
+
+**Result**: ✅ Each byte counted exactly once
+
+### 2. TLS Passthrough Connection
+
+```
+Client (TLS) → SmartProxy → Target Server (TLS)
+```
+
+1. Connection waits for initial data to detect TLS
+2. TLS handshake detected, SNI extracted
+3. Route matched, `setupDirectConnection()` called
+4. Initial chunk stored in `pendingData` (NOT counted yet)
+5. On target connect, `pendingData` written to target (still not counted)
+6. `setupBidirectionalForwarding()` counts ALL bytes including initial chunk
+
+**Result**: ✅ Each byte counted exactly once
+
+### 3. TLS Termination via HttpProxy
+
+```
+Client (TLS) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. TLS connection detected with `tls.mode = "terminate"`
+2. `forwardToHttpProxy()` called:
+   - Initial chunk: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+3. Proxy connection created to HttpProxy on localhost
+4. `setupBidirectionalForwarding()` handles subsequent data
+
+**Result**: ✅ Each byte counted exactly once
+
+### 4. HTTP Connection via HttpProxy
+
+```
+Client (HTTP) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. Connection on configured HTTP port (`useHttpProxy` ports)
+2. Same flow as TLS termination
+3. All byte counting identical to TLS termination
+
+**Result**: ✅ Each byte counted exactly once
+
+### 5. NFTables Forwarding
+
+```
+Client → [Kernel NFTables] → Target Server
+```
+
+1. Connection detected, route matched with `forwardingEngine: 'nftables'`
+2. Connection marked as `usingNetworkProxy = true`
+3. NO application-level forwarding (kernel handles packet routing)
+4. NO byte counting in application layer
+
+**Result**: ✅ No counting (correct - kernel handles everything)
+
+## Special Cases
+
+### PROXY Protocol
+- PROXY protocol headers sent to backend servers are NOT counted in client metrics
+- Only actual client data is counted
+- **Correct behavior**: Protocol overhead is not client data
+
+### TLS Alerts
+- TLS alerts (e.g., for missing SNI) are counted as sent bytes
+- **Correct behavior**: Alerts are actual data sent to the client
+
+### Initial Chunks
+- **Direct connections**: Stored in `pendingData`, counted when forwarded
+- **HttpProxy connections**: Counted immediately upon receipt
+- **Both approaches**: Count each byte exactly once
+
+## Verification Methodology
+
+1. **Code Analysis**: Searched for all instances of:
+   - `bytesReceived +=` and `bytesSent +=`
+   - `recordBytes()` calls
+   - Data forwarding implementations
+
+2. **Flow Tracing**: Followed data path for each connection type from entry to exit
+
+3. **Handler Review**: Examined all forwarding handlers to ensure no additional counting
+
+## Findings
+
+### ✅ No Double Counting Detected
+
+- Each byte is counted exactly once in the direction it flows
+- Connection records and metrics are updated consistently
+- No overlapping or duplicate counting logic found
+
+### Areas of Excellence
+
+1. **Centralized Counting**: All byte counting happens in just two files
+2. **Consistent Pattern**: Uses `setupBidirectionalForwarding()` with callbacks
+3. **Clear Separation**: Forwarding handlers don't interfere with proxy metrics
+
+## Recommendations
+
+1. **Debug Logging**: Add optional debug logging to verify byte counts in production:
+   ```typescript
+   if (settings.debugByteCount) {
+     logger.log('debug', `Bytes counted: ${connectionId} +${bytes} (total: ${record.bytesReceived})`);
+   }
+   ```
+
+2. **Unit Tests**: Create specific tests to ensure byte counting accuracy:
+   - Test initial chunk handling
+   - Test PROXY protocol overhead exclusion
+   - Test HttpProxy forwarding accuracy
+
+3. **Protocol Overhead Tracking**: Consider separately tracking:
+   - PROXY protocol headers
+   - TLS handshake bytes
+   - HTTP headers vs body
+
+4. **NFTables Documentation**: Clearly document that NFTables-forwarded connections are not included in application metrics
+
+## Conclusion
+
+SmartProxy's byte counting implementation is **robust and accurate**. The design ensures that each byte is counted exactly once, with clear separation between connection tracking and metrics collection. No remediation is required.

+# SmartProxy Development Hints
+
+## Byte Tracking and Metrics
+
+### Throughput Drift Issue (Fixed)
+
+**Problem**: Throughput numbers were gradually increasing over time for long-lived connections.
+
+**Root Cause**: The `byRoute()` and `byIP()` methods were dividing cumulative total bytes (since connection start) by the window duration, causing rates to appear higher as connections aged:
+- Hour 1: 1GB total / 60s = 17 MB/s ✓
+- Hour 2: 2GB total / 60s = 34 MB/s ✗ (appears doubled!)
+- Hour 3: 3GB total / 60s = 50 MB/s ✗ (keeps rising!)
+
+**Solution**: Implemented dedicated ThroughputTracker instances for each route and IP address:
+- Each route and IP gets its own throughput tracker with per-second sampling
+- Samples are taken every second and stored in a circular buffer
+- Rate calculations use actual samples within the requested window
+- Default window is now 1 second for real-time accuracy
+
+### What Gets Counted (Network Interface Throughput)
+
+The byte tracking is designed to match network interface throughput (what Unifi/network monitoring tools show):
+
+**Counted bytes include:**
+- All application data
+- TLS handshakes and protocol overhead
+- TLS record headers and encryption padding
+- HTTP headers and protocol data
+- WebSocket frames and protocol overhead
+- TLS alerts sent to clients
+
+**NOT counted:**
+- PROXY protocol headers (sent to backend, not client)
+- TCP/IP headers (handled by OS, not visible at application layer)
+
+**Byte direction:**
+- `bytesReceived`: All bytes received FROM the client on the incoming connection
+- `bytesSent`: All bytes sent TO the client on the incoming connection
+- Backend connections are separate and not mixed with client metrics
+
+### Double Counting Issue (Fixed)
+
+**Problem**: Initial data chunks were being counted twice in the byte tracking:
+1. Once when stored in `pendingData` in `setupDirectConnection()`
+2. Again when the data flowed through bidirectional forwarding
+
+**Solution**: Removed the byte counting when storing initial chunks. Bytes are now only counted when they actually flow through the `setupBidirectionalForwarding()` callbacks.
+
+### HttpProxy Metrics (Fixed)
+
+**Problem**: HttpProxy forwarding was updating connection record byte counts but not calling `metricsCollector.recordBytes()`, resulting in missing throughput data.
+
+**Solution**: Added `metricsCollector.recordBytes()` calls to the HttpProxy bidirectional forwarding callbacks.
+
+### Metrics Architecture
+
+The metrics system has multiple layers:
+1. **Connection Records** (`record.bytesReceived/bytesSent`): Track total bytes per connection
+2. **Global ThroughputTracker**: Accumulates bytes between samples for overall rate calculations
+3. **Per-Route ThroughputTrackers**: Dedicated tracker for each route with per-second sampling
+4. **Per-IP ThroughputTrackers**: Dedicated tracker for each IP with per-second sampling
+5. **connectionByteTrackers**: Track cumulative bytes and metadata for active connections
+
+Key features:
+- All throughput trackers sample every second (1Hz)
+- Each tracker maintains a circular buffer of samples (default: 1 hour retention)
+- Rate calculations are accurate for any requested window (default: 1 second)
+- All byte counting happens exactly once at the data flow point
+- Unused route/IP trackers are automatically cleaned up when connections close
+
+### Understanding "High" Byte Counts
+
+If byte counts seem high compared to actual application data, remember:
+- TLS handshakes can be 1-5KB depending on cipher suites and certificates
+- Each TLS record has 5 bytes of header overhead
+- TLS encryption adds 16-48 bytes of padding/MAC per record
+- HTTP/2 has additional framing overhead
+- WebSocket has frame headers (2-14 bytes per message)
+
+This overhead is real network traffic and should be counted for accurate throughput metrics.
+
+### Byte Counting Paths
+
+There are two mutually exclusive paths for connections:
+
+1. **Direct forwarding** (route-connection-handler.ts):
+   - Used for TCP passthrough, TLS passthrough, and direct connections
+   - Bytes counted in `setupBidirectionalForwarding` callbacks
+   - Initial chunk NOT counted separately (flows through bidirectional forwarding)
+
+2. **HttpProxy forwarding** (http-proxy-bridge.ts):
+   - Used for TLS termination (terminate, terminate-and-reencrypt)
+   - Initial chunk counted when written to proxy
+   - All subsequent bytes counted in `setupBidirectionalForwarding` callbacks
+   - This is the ONLY counting point for these connections
+
+### Byte Counting Audit (2025-01-06)
+
+A comprehensive audit was performed to verify byte counting accuracy:
+
+**Audit Results:**
+- ✅ No double counting detected in any connection flow
+- ✅ Each byte counted exactly once in each direction
+- ✅ Connection records and metrics updated consistently
+- ✅ PROXY protocol headers correctly excluded from client metrics
+- ✅ NFTables forwarded connections correctly not counted (kernel handles)
+
+**Key Implementation Points:**
+- All byte counting happens in only 2 files: `route-connection-handler.ts` and `http-proxy-bridge.ts`
+- Both use the same pattern: increment `record.bytesReceived/Sent` AND call `metricsCollector.recordBytes()`
+- Initial chunks handled correctly: stored but not counted until forwarded
+- TLS alerts counted as sent bytes (correct - they are sent to client)
+
+For full audit details, see `readme.byte-counting-audit.md`
+
+## Connection Cleanup
+
+### Zombie Connection Detection
+
+The connection manager performs comprehensive zombie detection every 10 seconds:
+- **Full zombies**: Both incoming and outgoing sockets destroyed but connection not cleaned up
+- **Half zombies**: One socket destroyed, grace period expired (5 minutes for TLS, 30 seconds for non-TLS)
+- **Stuck connections**: Data received but none sent back after threshold (5 minutes for TLS, 60 seconds for non-TLS)
+
+### Cleanup Queue
+
+Connections are cleaned up through a batched queue system:
+- Batch size: 100 connections
+- Processing triggered immediately when batch size reached
+- Otherwise processed after 100ms delay
+- Prevents overwhelming the system during mass disconnections
+
+## Keep-Alive Handling
+
+Keep-alive connections receive special treatment based on `keepAliveTreatment` setting:
+- **standard**: Normal timeout applies
+- **extended**: Timeout multiplied by `keepAliveInactivityMultiplier` (default 6x)
+- **immortal**: No timeout, connections persist indefinitely
+
+## PROXY Protocol
+
+The system supports both receiving and sending PROXY protocol:
+- **Receiving**: Automatically detected from trusted proxy IPs (configured in `proxyIPs`)
+- **Sending**: Enabled per-route or globally via `sendProxyProtocol` setting
+- Real client IP is preserved and used for all connection tracking and security checks
+
+## Metrics and Throughput Calculation
+
+The metrics system tracks throughput using per-second sampling:
+
+1. **Byte Recording**: Bytes are recorded as data flows through connections
+2. **Sampling**: Every second, accumulated bytes are stored as a sample
+3. **Rate Calculation**: Throughput is calculated by summing bytes over a time window
+4. **Per-Route/IP Tracking**: Separate ThroughputTracker instances for each route and IP
+
+Key implementation details:
+- Bytes are recorded in the bidirectional forwarding callbacks
+- The instant() method returns throughput over the last 1 second
+- The recent() method returns throughput over the last 10 seconds
+- Custom windows can be specified for different averaging periods
+
+### Throughput Spikes Issue
+
+There's a fundamental difference between application-layer and network-layer throughput:
+
+**Application Layer (what we measure)**:
+- Bytes are recorded when delivered to/from the application
+- Large chunks can arrive "instantly" due to kernel/Node.js buffering
+- Shows spikes when buffers are flushed (e.g., 20MB in 1 second = 160 Mbit/s)
+
+**Network Layer (what Unifi shows)**:
+- Actual packet flow through the network interface
+- Limited by physical network speed (e.g., 20 Mbit/s)
+- Data transfers over time, not in bursts
+
+The spikes occur because:
+1. Data flows over network at 20 Mbit/s (takes 8 seconds for 20MB)
+2. Kernel/Node.js buffers this incoming data
+3. When buffer is flushed, application receives large chunk at once
+4. We record entire chunk in current second, creating artificial spike
+
+**Potential Solutions**:
+1. Use longer window for "instant" measurements (e.g., 5 seconds instead of 1)
+2. Track socket write backpressure to estimate actual network flow
+3. Implement bandwidth estimation based on connection duration
+4. Accept that application-layer != network-layer throughput
+
+## Connection Limiting
+
+### Per-IP Connection Limits
+- SmartProxy tracks connections per IP address in the SecurityManager
+- Default limit is 100 connections per IP (configurable via `maxConnectionsPerIP`)
+- Connection rate limiting is also enforced (default 300 connections/minute per IP)
+- HttpProxy has been enhanced to also enforce per-IP limits when forwarding from SmartProxy
+
+### Route-Level Connection Limits
+- Routes can define `security.maxConnections` to limit connections per route
+- ConnectionManager tracks connections by route ID using a separate Map
+- Limits are enforced in RouteConnectionHandler before forwarding
+- Connection is tracked when route is matched: `trackConnectionByRoute(routeId, connectionId)`
+
+### HttpProxy Integration
+- When SmartProxy forwards to HttpProxy for TLS termination, it sends a `CLIENT_IP:<ip>\r\n` header
+- HttpProxy parses this header to track the real client IP, not the localhost IP
+- This ensures per-IP limits are enforced even for forwarded connections
+- The header is parsed in the connection handler before any data processing
+
+### Memory Optimization
+- Periodic cleanup runs every 60 seconds to remove:
+  - IPs with no active connections
+  - Expired rate limit timestamps (older than 1 minute)
+- Prevents memory accumulation from many unique IPs over time
+- Cleanup is automatic and runs in background with `unref()` to not keep process alive
+
+### Connection Cleanup Queue
+- Cleanup queue processes connections in batches to prevent overwhelming the system
+- Race condition prevention using `isProcessingCleanup` flag
+- Try-finally block ensures flag is always reset even if errors occur
+- New connections added during processing are queued for next batch
+
+### Important Implementation Notes
+- Always use `NodeJS.Timeout` type instead of `NodeJS.Timer` for interval/timeout references
+- IPv4/IPv6 normalization is handled (e.g., `::ffff:127.0.0.1` and `127.0.0.1` are treated as the same IP)
+- Connection limits are checked before route matching to prevent DoS attacks
+- SharedSecurityManager supports checking route-level limits via optional parameter
+
+## Log Deduplication
+
+To reduce log spam during high-traffic scenarios or attacks, SmartProxy implements log deduplication for repetitive events:
+
+### How It Works
+- Similar log events are batched and aggregated over a 5-second window
+- Instead of logging each event individually, a summary is emitted
+- Events are grouped by type and deduplicated by key (e.g., IP address, reason)
+
+### Deduplicated Event Types
+1. **Connection Rejections** (`connection-rejected`):
+   - Groups by rejection reason (global-limit, route-limit, etc.)
+   - Example: "Rejected 150 connections (reasons: global-limit: 100, route-limit: 50)"
+
+2. **IP Rejections** (`ip-rejected`):
+   - Groups by IP address
+   - Shows top offenders with rejection counts and reasons
+   - Example: "Rejected 500 connections from 10 IPs (top offenders: 192.168.1.100 (200x, rate-limit), ...)"
+
+3. **Connection Cleanups** (`connection-cleanup`):
+   - Groups by cleanup reason (normal, timeout, error, zombie, etc.)
+   - Example: "Cleaned up 250 connections (reasons: normal: 200, timeout: 30, error: 20)"
+
+4. **IP Tracking Cleanup** (`ip-cleanup`):
+   - Summarizes periodic IP cleanup operations
+   - Example: "IP tracking cleanup: removed 50 entries across 5 cleanup cycles"
+
+### Configuration
+- Default flush interval: 5 seconds
+- Maximum batch size: 100 events (triggers immediate flush)
+- Global periodic flush: Every 10 seconds (ensures logs are emitted regularly)
+- Process exit handling: Logs are flushed on SIGINT/SIGTERM
+
+### Benefits
+- Reduces log volume during attacks or high traffic
+- Provides better overview of patterns (e.g., which IPs are attacking)
+- Improves log readability and analysis
+- Prevents log storage overflow
+- Maintains detailed information in aggregated form
+
+### Log Output Examples
+
+Instead of hundreds of individual logs:
+```
+Connection rejected
+Connection rejected
+Connection rejected
+... (repeated 500 times)
+```
+
+You'll see:
+```
+[SUMMARY] Rejected 500 connections from 10 IPs in 5s (rate-limit: 350, per-ip-limit: 150) (top offenders: 192.168.1.100 (200x, rate-limit), 10.0.0.1 (150x, per-ip-limit))
+```
+
+Instead of:
+```
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 266
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 265
+... (repeated 266 times)
+```
+
+You'll see:
+```
+[SUMMARY] 266 HttpProxy connections terminated in 5s (reasons: client_closed: 266, activeConnections: 0)
+```
+
+### Rapid Event Handling
+- During attacks or high-volume scenarios, logs are flushed more frequently
+- If 50+ events occur within 1 second, immediate flush is triggered
+- Prevents memory buildup during flooding attacks
+- Maintains real-time visibility during incidents
+
+## Custom Certificate Provision Function
+
+The `certProvisionFunction` feature has been implemented to allow users to provide their own certificate generation logic.
+
+### Implementation Details
+
+1. **Type Definition**: The function must return `Promise<TSmartProxyCertProvisionObject>` where:
+   - `TSmartProxyCertProvisionObject = plugins.tsclass.network.ICert | 'http01'`
+   - Return `'http01'` to fallback to Let's Encrypt
+   - Return a certificate object for custom certificates
+
+2. **Certificate Manager Changes**:
+   - Added `certProvisionFunction` property to CertificateManager
+   - Modified `provisionAcmeCertificate()` to check custom function first
+   - Custom certificates are stored with source type 'custom'
+   - Expiry date extraction currently defaults to 90 days
+
+3. **Configuration Options**:
+   - `certProvisionFunction`: The custom provision function
+   - `certProvisionFallbackToAcme`: Whether to fallback to ACME on error (default: true)
+
+4. **Usage Example**:
+```typescript
+new SmartProxy({
+  certProvisionFunction: async (domain: string) => {
+    if (domain === 'internal.example.com') {
+      return {
+        cert: customCert,
+        key: customKey,
+        ca: customCA
+      } as unknown as TSmartProxyCertProvisionObject;
+    }
+    return 'http01'; // Use Let's Encrypt
+  },
+  certProvisionFallbackToAcme: true
+})
+```
+
+5. **Testing Notes**:
+   - Type assertions through `unknown` are needed in tests due to strict interface typing
+   - Mock certificate objects work for testing but need proper type casting
+   - The actual certificate parsing for expiry dates would need a proper X.509 parser
+
+### Future Improvements
+
+1. Implement proper certificate expiry date extraction using X.509 parsing
+2. Add support for returning expiry date with custom certificates
+3. Consider adding validation for custom certificate format
+4. Add events/hooks for certificate provisioning lifecycle
