feat(proxy): Start implementing PROXY protocol support and WrappedSocket class for enhanced client IP handling

- Updated socket handling to prevent connection accumulation in chained proxies.
- Introduced centralized bidirectional forwarding for consistent socket management.
- Enhanced cleanup logic to ensure immediate closure of sockets when one closes.
- Added tests to verify connection behavior under various scenarios, including backend failures and rapid reconnections.

+# Changelog
+
+## 2025-06-01 - 19.5.19 - fix(smartproxy)
+Fix connection handling and improve route matching edge cases
+
+- Enhanced cleanup logic to prevent connection accumulation under rapid retry scenarios
+- Improved matching for wildcard domains and path parameters in the route configuration
+- Minor refactoring in async utilities and internal socket handling for better performance
+- Updated test suites and documentation for clearer configuration examples
+
+## 2025-05-29 - 19.5.3 - fix(smartproxy)
+Fix route security configuration location and improve ACME timing tests and socket mock implementations
+
+- Move route security from action.security to the top-level route.security to correctly enforce IP allow/block lists (addresses failing in test.route-security.ts)
+- Update readme.problems.md to document the routing security configuration issue with proper instructions
+- Adjust certificate metadata in certs/static-route/meta.json with updated timestamps
+- Update test.acme-timing.ts to export default tap.start() instead of tap.start() to ensure proper parsing
+- Improve socket simulation and event handling mocks in test.http-fix-verification.ts and test.http-forwarding-fix.ts to more reliably mimic net.Socket behavior
+- Minor adjustments in multiple test files to ensure proper port binding, race condition handling and route lookups (e.g. getRoutesForPort implementation)
+
+## 2025-05-29 - 19.5.2 - fix(test)
+Fix ACME challenge route creation and HTTP request parsing in tests
+
+- Replaced the legacy ACME email 'test@example.com' with 'test@acmetest.local' to avoid forbidden domain issues.
+- Mocked the CertificateManager in test/test.acme-route-creation to simulate immediate ACME challenge route addition.
+- Adjusted updateRoutes callback to capture and verify challenge route creation.
+- Enhanced the HTTP request parsing in socket handler by capturing and asserting parsed request details (method, path, headers).
+
+## 2025-05-29 - 19.5.1 - fix(socket-handler)
+Fix socket handler race condition by differentiating between async and sync handlers. Now, async socket handlers complete their setup before initial data is emitted, ensuring that no data is lost. Documentation and tests have been updated to reflect this change.
+
+- Added detailed explanation in readme.hints.md about the race condition issue, root cause, and solution implementation.
+- Provided a code snippet that checks if the socket handler returns a Promise and waits for its resolution before emitting initial data.
+- Updated tests (test.socket-handler-race.ts, test.socket-handler.simple.ts, test.socket-handler.ts) to verify correct behavior of async handlers.
+
+## 2025-05-28 - 19.5.0 - feat(socket-handler)
+Add socket-handler support for custom socket handling in SmartProxy
+
+- Introduce new action type 'socket-handler' in IRouteAction to allow users to provide a custom socket handler function.
+- Update the RouteConnectionHandler to detect 'socket-handler' actions and invoke the handler with the raw socket, giving full control to the user.
+- Provide optional context (such as route configuration, client IP, and port) to the socket handler if needed.
+- Add helper functions in route-helpers for creating socket handler routes and common patterns like echo, proxy, and line-based protocols.
+- Include a detailed implementation plan and usage examples in readme.plan.md.
+
+## 2025-05-28 - 19.4.3 - fix(smartproxy)
+Improve port binding intelligence and ACME challenge route management; update route configuration tests and dependency versions.
+
+- Bumped dev dependency versions in package.json (tsbuild from ^2.5.1 to ^2.6.4, tstest from ^1.9.0 to ^2.3.1, @types/node updated, smartfile from ^11.2.0 to ^11.2.5, smartlog from ^3.1.7 to ^3.1.8)
+- Removed readme.plan.md containing legacy development plan information
+- Normalized route configuration properties across tests (using 'ports' and 'domains' instead of legacy 'port' or 'domain')
+- Enhanced PortManager with reference counting and smarter port conflict detection to avoid redundant bindings
+- Refined ACME challenge route integration to merge with existing port bindings and improve error handling
+- Adjusted test expectations (e.g. using toEqual instead of toBe, and improved timeout handling) to align with current API changes
+
+## 2025-05-20 - 19.4.2 - fix(dependencies)
+Update dependency versions: upgrade @types/node to ^22.15.20 and @push.rocks/smartlog to ^3.1.7 in package.json
+
+- Bump @types/node from ^22.15.19 to ^22.15.20
+- Bump @push.rocks/smartlog from ^3.1.3 to ^3.1.7
+
+## 2025-05-20 - 19.4.1 - fix(smartproxy)
+Bump @push.rocks/smartlog to ^3.1.3 and improve ACME port binding behavior in SmartProxy
+
+- Updated package.json to use @push.rocks/smartlog version ^3.1.3
+- Enhanced tests (test.http-port8080-simple.ts) to verify improved port binding intelligence for ACME challenge routes
+- Ensured that existing port listeners are reused and not re-bound when updating routes
+
+## 2025-05-20 - 19.4.0 - feat(certificate-manager, smart-proxy)
+Improve port binding intelligence for ACME challenges
+
+- Reordered SmartProxy initialization flow to bind ports before initializing the certificate manager

+
+## 2025-05-20 - 19.3.14 - fix(certificate-manager, smart-proxy)
+Add error handling around logger calls in route update callback
+
+- Added try/catch blocks around logger calls in certificate-manager.ts

+# SmartProxy Project Hints
+
+## Project Overview
+- Package: `@push.rocks/smartproxy` – high-performance proxy supporting HTTP(S), TCP, WebSocket, and ACME integration.
+- Written in TypeScript, compiled output in `dist_ts/`, uses ESM with NodeNext resolution.
+
+## Important: ACME Configuration in v19.0.0
+- **Breaking Change**: ACME configuration must be placed within individual route TLS settings, not at the top level
+- Route-level ACME config is the ONLY way to enable SmartAcme initialization
+- SmartCertManager requires email in route config for certificate acquisition
+- Top-level ACME configuration is ignored in v19.0.0
+
+## Repository Structure
+- `ts/` – TypeScript source files:
+  - `index.ts` exports main modules.
+  - `plugins.ts` centralizes native and third-party imports.
+  - Subdirectories: `networkproxy/`, `nftablesproxy/`, `port80handler/`, `redirect/`, `smartproxy/`.
+  - Key classes: `ProxyRouter` (`classes.router.ts`), `SmartProxy` (`classes.smartproxy.ts`), plus handlers/managers.
+- `dist_ts/` – transpiled `.js` and `.d.ts` files mirroring `ts/` structure.
+- `test/` – test suites in TypeScript:
+  - `test.router.ts` – routing logic (hostname matching, wildcards, path parameters, config management).
+  - `test.smartproxy.ts` – proxy behavior tests (TCP forwarding, SNI handling, concurrency, chaining, timeouts).
+  - `test/helpers/` – utilities (e.g., certificates).
+- `assets/certs/` – placeholder certificates for ACME and TLS.
+
+## Development Setup
+- Requires `pnpm` (v10+).
+- Install dependencies: `pnpm install`.
+- Build: `pnpm build` (runs `tsbuild --web --allowimplicitany`).
+- Test: `pnpm test` (runs `tstest test/`).
+- Format: `pnpm format` (runs `gitzone format`).
+
+## How to Test
+
+### Test Structure
+Tests use tapbundle from `@git.zone/tstest`. The correct pattern is:
+
+```typescript
+import { tap, expect } from '@git.zone/tstest/tapbundle';
+
+tap.test('test description', async () => {
+  // Test logic here
+  expect(someValue).toEqual(expectedValue);
+});
+
+// IMPORTANT: Must end with tap.start()
+tap.start();
+```
+
+### Expect Syntax (from @push.rocks/smartexpect)
+```typescript
+// Type assertions
+expect('hello').toBeTypeofString();
+expect(42).toBeTypeofNumber();
+
+// Equality
+expect('hithere').toEqual('hithere');
+
+// Negated assertions
+expect(1).not.toBeTypeofString();
+
+// Regular expressions
+expect('hithere').toMatch(/hi/);
+
+// Numeric comparisons
+expect(5).toBeGreaterThan(3);
+expect(0.1 + 0.2).toBeCloseTo(0.3, 10);
+
+// Arrays
+expect([1, 2, 3]).toContain(2);
+expect([1, 2, 3]).toHaveLength(3);
+
+// Async assertions
+await expect(asyncFunction()).resolves.toEqual('expected');
+await expect(asyncFunction()).resolves.withTimeout(5000).toBeTypeofString();
+
+// Complex object navigation
+expect(complexObject)
+  .property('users')
+  .arrayItem(0)
+  .property('name')
+  .toEqual('Alice');
+```
+
+### Test Modifiers
+- `tap.only.test()` - Run only this test
+- `tap.skip.test()` - Skip a test
+- `tap.timeout()` - Set test-specific timeout
+
+### Running Tests
+- All tests: `pnpm test`
+- Specific test: `tsx test/test.router.ts`
+- With options: `tstest test/**/*.ts --verbose --timeout 60`
+
+### Test File Requirements
+- Must start with `test.` prefix
+- Must use `.ts` extension
+- Must call `tap.start()` at the end
+
+## Coding Conventions
+- Import modules via `plugins.ts`:
+  ```ts
+  import * as plugins from './plugins.ts';
+  const server = new plugins.http.Server();
+  ```
+- Reference plugins with full path: `plugins.acme`, `plugins.smartdelay`, `plugins.minimatch`, etc.
+- Path patterns support globs (`*`) and parameters (`:param`) in `ProxyRouter`.
+- Wildcard hostname matching leverages `minimatch` patterns.
+
+## Key Components
+- **ProxyRouter**
+  - Methods: `routeReq`, `routeReqWithDetails`.
+  - Hostname matching: case-insensitive, strips port, supports exact, wildcard, TLD, complex patterns.
+  - Path routing: exact, wildcard, parameter extraction (`pathParams`), returns `pathMatch` and `pathRemainder`.
+  - Config API: `setNewProxyConfigs`, `addProxyConfig`, `removeProxyConfig`, `getHostnames`, `getProxyConfigs`.
+- **SmartProxy**
+  - Manages one or more `net.Server` instances to forward TCP streams.
+  - Options: `preserveSourceIP`, `defaultAllowedIPs`, `globalPortRanges`, `sniEnabled`.
+  - DomainConfigManager: round-robin selection for multiple target IPs.
+  - Graceful shutdown in `stop()`, ensures no lingering servers or sockets.
+
+## Notable Points
+- **TSConfig**: `module: NodeNext`, `verbatimModuleSyntax`, allows `.js` extension imports in TS.
+- Mermaid diagrams and architecture flows in `readme.md` illustrate component interactions and protocol flows.
+- CLI entrypoint (`cli.js`) supports command-line usage (ACME, proxy controls).
+- ACME and certificate handling via `Port80Handler` and `helpers.certificates.ts`.
+
+## ACME/Certificate Configuration Example (v19.0.0)
+```typescript
+const proxy = new SmartProxy({
+  routes: [{
+    name: 'example.com',
+    match: { domains: 'example.com', ports: 443 },
+    action: {
+      type: 'forward',
+      target: { host: 'localhost', port: 8080 },
+      tls: {
+        mode: 'terminate',
+        certificate: 'auto',
+        acme: {  // ACME config MUST be here, not at top level
+          email: 'ssl@example.com',
+          useProduction: false,
+          challengePort: 80
+        }
+      }
+    }
+  }]
+});
+```
+
+## TODOs / Considerations
+- Ensure import extensions in source match build outputs (`.ts` vs `.js`).
+- Update `plugins.ts` when adding new dependencies.
+- Maintain test coverage for new routing or proxy features.
+- Keep `ts/` and `dist_ts/` in sync after refactors.
+- Consider implementing top-level ACME config support for backward compatibility
+
+## HTTP-01 ACME Challenge Fix (v19.3.8)
+
+### Issue
+Non-TLS connections on ports configured in `useHttpProxy` were not being forwarded to HttpProxy. This caused ACME HTTP-01 challenges to fail when the ACME port (usually 80) was included in `useHttpProxy`.
+
+### Root Cause
+In the `RouteConnectionHandler.handleForwardAction` method, only connections with TLS settings (mode: 'terminate' or 'terminate-and-reencrypt') were being forwarded to HttpProxy. Non-TLS connections were always handled as direct connections, even when the port was configured for HttpProxy.
+
+### Solution
+Added a check for non-TLS connections on ports listed in `useHttpProxy`:
+```typescript
+// No TLS settings - check if this port should use HttpProxy
+const isHttpProxyPort = this.settings.useHttpProxy?.includes(record.localPort);
+
+if (isHttpProxyPort && this.httpProxyBridge.getHttpProxy()) {
+  // Forward non-TLS connections to HttpProxy if configured
+  this.httpProxyBridge.forwardToHttpProxy(/*...*/);
+  return;
+}
+```
+
+### Test Coverage
+- `test/test.http-fix-unit.ts` - Unit tests verifying the fix
+- Tests confirm that non-TLS connections on HttpProxy ports are properly forwarded
+- Tests verify that non-HttpProxy ports still use direct connections
+
+### Configuration Example
+```typescript
+const proxy = new SmartProxy({
+  useHttpProxy: [80], // Enable HttpProxy for port 80
+  httpProxyPort: 8443,
+  acme: {
+    email: 'ssl@example.com',
+    port: 80
+  },
+  routes: [
+    // Your routes here
+  ]
+});
+```
+
+## ACME Certificate Provisioning Timing Fix (v19.3.9)
+
+### Issue
+Certificate provisioning would start before ports were listening, causing ACME HTTP-01 challenges to fail with connection refused errors.
+
+### Root Cause
+SmartProxy initialization sequence:
+1. Certificate manager initialized → immediately starts provisioning
+2. Ports start listening (too late for ACME challenges)
+
+### Solution
+Deferred certificate provisioning until after ports are ready:
+```typescript
+// SmartCertManager.initialize() now skips automatic provisioning
+// SmartProxy.start() calls provisionAllCertificates() directly after ports are listening
+```
+
+### Test Coverage
+- `test/test.acme-timing-simple.ts` - Verifies proper timing sequence
+
+### Migration
+Update to v19.3.9+, no configuration changes needed.
+
+## Socket Handler Race Condition Fix (v19.5.0)
+
+### Issue
+Initial data chunks were being emitted before async socket handlers had completed setup, causing data loss when handlers performed async operations before setting up data listeners.
+
+### Root Cause
+The `handleSocketHandlerAction` method was using `process.nextTick` to emit initial chunks regardless of whether the handler was sync or async. This created a race condition where async handlers might not have their listeners ready when the initial data was emitted.
+
+### Solution
+Differentiated between sync and async handlers:
+```typescript
+const result = route.action.socketHandler(socket);
+
+if (result instanceof Promise) {
+  // Async handler - wait for completion before emitting initial data
+  result.then(() => {
+    if (initialChunk && initialChunk.length > 0) {
+      socket.emit('data', initialChunk);
+    }
+  }).catch(/*...*/);
+} else {
+  // Sync handler - use process.nextTick as before
+  if (initialChunk && initialChunk.length > 0) {
+    process.nextTick(() => {
+      socket.emit('data', initialChunk);
+    });
+  }
+}
+```
+
+### Test Coverage
+- `test/test.socket-handler-race.ts` - Specifically tests async handlers with delayed listener setup
+- Verifies that initial data is received even when handler sets up listeners after async work
+
+### Usage Note
+Socket handlers require initial data from the client to trigger routing (not just a TLS handshake). Clients must send at least one byte of data for the handler to be invoked.
+
+## Route-Specific Security Implementation (v19.5.3)
+
+### Issue
+Route-specific security configurations (ipAllowList, ipBlockList, authentication) were defined in the route types but not enforced at runtime.
+
+### Root Cause
+The RouteConnectionHandler only checked global IP validation but didn't enforce route-specific security rules after matching a route.
+
+### Solution
+Added security checks after route matching:
+```typescript
+// Apply route-specific security checks
+const routeSecurity = route.action.security || route.security;
+if (routeSecurity) {
+  // Check IP allow/block lists
+  if (routeSecurity.ipAllowList || routeSecurity.ipBlockList) {
+    const isIPAllowed = this.securityManager.isIPAuthorized(
+      remoteIP,
+      routeSecurity.ipAllowList || [],
+      routeSecurity.ipBlockList || []
+    );
+    
+    if (!isIPAllowed) {
+      socket.end();
+      this.connectionManager.cleanupConnection(record, 'route_ip_blocked');
+      return;
+    }
+  }
+}
+```
+
+### Test Coverage
+- `test/test.route-security-unit.ts` - Unit tests verifying SecurityManager.isIPAuthorized logic
+- Tests confirm IP allow/block lists work correctly with glob patterns
+
+### Configuration Example
+```typescript
+const routes: IRouteConfig[] = [{
+  name: 'secure-api',
+  match: { ports: 8443, domains: 'api.example.com' },
+  action: {
+    type: 'forward',
+    target: { host: 'localhost', port: 3000 },
+    security: {
+      ipAllowList: ['192.168.1.*', '10.0.0.0/8'],    // Allow internal IPs
+      ipBlockList: ['192.168.1.100'],                // But block specific IP
+      maxConnections: 100,                            // Per-route limit (TODO)
+      authentication: {                               // HTTP-only, requires TLS termination
+        type: 'basic',
+        credentials: [{ username: 'api', password: 'secret' }]
+      }
+    }
+  }
+}];
+```
+
+### Notes
+- IP lists support glob patterns (via minimatch): `192.168.*`, `10.?.?.1`
+- Block lists take precedence over allow lists
+- Authentication requires TLS termination (cannot be enforced on passthrough/direct connections)
+- Per-route connection limits are not yet implemented
+- Security is defined at the route level (route.security), not in the action
+- Route matching is based solely on match criteria; security is enforced after matching
+
+## Performance Issues Investigation (v19.5.3+)
+
+### Critical Blocking Operations Found
+1. **Busy Wait Loop** in `ts/proxies/nftables-proxy/nftables-proxy.ts:235-238`
+   - Blocks entire event loop with `while (Date.now() < waitUntil) {}`
+   - Should use `await new Promise(resolve => setTimeout(resolve, delay))`
+
+2. **Synchronous Filesystem Operations**
+   - Certificate management uses `fs.existsSync()`, `fs.mkdirSync()`, `fs.readFileSync()`
+   - NFTables proxy uses `execSync()` for system commands
+   - Certificate store uses `ensureDirSync()`, `fileExistsSync()`, `removeManySync()`
+
+3. **Memory Leak Risks**
+   - Several `setInterval()` calls without storing references for cleanup
+   - Event listeners added without proper cleanup in error paths
+   - Missing `removeAllListeners()` calls in some connection cleanup scenarios
+
+### Performance Recommendations
+- Replace all sync filesystem operations with async alternatives

+
+## Socket Error Handling Fix (v19.5.11+)
+
+### Issue
+Server crashed with unhandled 'error' event when backend connections failed (ECONNREFUSED). Also caused memory leak with rising active connection count as failed connections weren't cleaned up properly.
+
+### Root Cause
+1. **Race Condition**: In forwarding handlers, sockets were created with `net.connect()` but error handlers were attached later, creating a window where errors could crash the server
+2. **Incomplete Cleanup**: When server connections failed, client sockets weren't properly cleaned up, leaving connection records in memory
+
+### Solution
+Created `createSocketWithErrorHandler()` utility that attaches error handlers immediately:
+```typescript
+// Before (race condition):
+const socket = net.connect(port, host);
+// ... other code ...
+socket.on('error', handler); // Too late!
+
+// After (safe):
+const socket = createSocketWithErrorHandler({
+  port, host,
+  onError: (error) => {
+    // Handle error immediately
+    clientSocket.destroy();
+  },
+  onConnect: () => {
+    // Set up forwarding
+  }
+});
+```
+
+### Changes Made
+1. **New Utility**: `ts/core/utils/socket-utils.ts` - Added `createSocketWithErrorHandler()`
+2. **Updated Handlers**:
+   - `https-passthrough-handler.ts` - Uses safe socket creation
+   - `https-terminate-to-http-handler.ts` - Uses safe socket creation
+3. **Connection Cleanup**: Client sockets destroyed immediately on server connection failure
+
+### Test Coverage
+- `test/test.socket-error-handling.node.ts` - Verifies server doesn't crash on ECONNREFUSED
+- `test/test.forwarding-error-fix.node.ts` - Tests forwarding handlers handle errors gracefully
+
+### Configuration
+No configuration changes needed. The fix is transparent to users.
+
+### Important Note
+The fix was applied in two places:
+1. **ForwardingHandler classes** (`https-passthrough-handler.ts`, etc.) - These are standalone forwarding utilities
+2. **SmartProxy route-connection-handler** (`route-connection-handler.ts`) - This is where the actual SmartProxy connection handling happens
+
+The critical fix for SmartProxy was in `setupDirectConnection()` method in route-connection-handler.ts, which now uses `createSocketWithErrorHandler()` to properly handle connection failures and clean up connection records.
+
+## Connection Cleanup Improvements (v19.5.12+)
+
+### Issue
+Connections were still counting up during rapid retry scenarios, especially when routing failed or backend connections were refused. This was due to:
+1. **Delayed Cleanup**: Using `initiateCleanupOnce` queued cleanup operations (batch of 100 every 100ms) instead of immediate cleanup
+2. **NFTables Memory Leak**: NFTables connections were never cleaned up, staying in memory forever
+3. **Connection Limit Bypass**: When max connections reached, connection record check happened after creation
+
+### Root Cause Analysis
+1. **Queued vs Immediate Cleanup**:
+   - `initiateCleanupOnce()`: Adds to cleanup queue, processes up to 100 connections every 100ms
+   - `cleanupConnection()`: Immediate synchronous cleanup
+   - Under rapid retries, connections were created faster than the queue could process them
+
+2. **NFTables Connections**: 
+   - Marked with `usingNetworkProxy = true` but never cleaned up
+   - Connection records stayed in memory indefinitely
+
+3. **Error Path Cleanup**:
+   - Many error paths used `socket.end()` (async) followed by cleanup
+   - Created timing windows where connections weren't fully cleaned
+
+### Solution
+1. **Immediate Cleanup**: Changed all error paths from `initiateCleanupOnce()` to `cleanupConnection()` for immediate cleanup
+2. **NFTables Cleanup**: Added socket close listener to clean up connection records when NFTables connections close
+3. **Connection Limit Fix**: Added null check after `createConnection()` to handle rejection properly
+
+### Changes Made in route-connection-handler.ts
+```typescript
+// 1. NFTables cleanup (line 551-553)
+socket.once('close', () => {
+  this.connectionManager.cleanupConnection(record, 'nftables_closed');
+});
+
+// 2. Connection limit check (line 93-96)
+const record = this.connectionManager.createConnection(socket);
+if (!record) {
+  // Connection was rejected due to limit - socket already destroyed
+  return;
+}
+
+// 3. Changed all error paths to use immediate cleanup
+// Before: this.connectionManager.initiateCleanupOnce(record, reason)
+// After: this.connectionManager.cleanupConnection(record, reason)
+```
+
+### Test Coverage
+- `test/test.rapid-retry-cleanup.node.ts` - Verifies connection cleanup under rapid retry scenarios
+- Test shows connection count stays at 0 even with 20 rapid retries with 50ms intervals
+- Confirms both ECONNREFUSED and routing failure scenarios are handled correctly
+
+### Performance Impact
+- **Positive**: No more connection accumulation under load
+- **Positive**: Immediate cleanup reduces memory usage
+- **Consideration**: More frequent cleanup operations, but prevents queue backlog
+
+### Migration Notes
+No configuration changes needed. The improvements are automatic and backward compatible.
+
+## Early Client Disconnect Handling (v19.5.13+)
+
+### Issue
+Connections were accumulating when clients connected but disconnected before sending data or during routing. This occurred in two scenarios:
+1. **TLS Path**: Clients connecting and disconnecting before sending initial TLS handshake data
+2. **Non-TLS Immediate Routing**: Clients disconnecting while backend connection was being established
+
+### Root Cause
+1. **Missing Cleanup Handlers**: During initial data wait and immediate routing, no close/end handlers were attached to catch early disconnections
+2. **Race Condition**: Backend connection attempts continued even after client disconnected, causing unhandled errors
+3. **Timing Window**: Between accepting connection and establishing full bidirectional flow, disconnections weren't properly handled
+
+### Solution
+1. **TLS Path Fix**: Added close/end handlers during initial data wait (lines 224-253 in route-connection-handler.ts)
+2. **Immediate Routing Fix**: Used `setupSocketHandlers` for proper handler attachment (lines 180-205)
+3. **Backend Error Handling**: Check if connection already closed before handling backend errors (line 1144)
+
+### Changes Made
+```typescript
+// 1. TLS path - handle disconnect before initial data
+socket.once('close', () => {
+  if (!initialDataReceived) {
+    this.connectionManager.cleanupConnection(record, 'closed_before_data');
+  }
+});
+
+// 2. Immediate routing path - proper handler setup
+setupSocketHandlers(socket, (reason) => {
+  if (!record.outgoing || record.outgoing.readyState !== 'open') {
+    if (record.outgoing && !record.outgoing.destroyed) {
+      record.outgoing.destroy(); // Abort pending backend connection
+    }
+    this.connectionManager.cleanupConnection(record, reason);
+  }
+}, undefined, 'immediate-route-client');
+
+// 3. Backend connection error handling
+onError: (error) => {
+  if (record.connectionClosed) {
+    logger.log('debug', 'Backend connection failed but client already disconnected');
+    return; // Client already gone, nothing to clean up
+  }
+  // ... normal error handling
+}
+```
+
+### Test Coverage
+- `test/test.connect-disconnect-cleanup.node.ts` - Comprehensive test for early disconnect scenarios
+- Tests verify connection count stays at 0 even with rapid connect/disconnect patterns
+- Covers immediate disconnect, delayed disconnect, and mixed patterns
+
+### Performance Impact
+- **Positive**: No more connection accumulation from early disconnects
+- **Positive**: Immediate cleanup reduces memory usage
+- **Positive**: Prevents resource exhaustion from rapid reconnection attempts
+
+### Migration Notes
+No configuration changes needed. The fix is automatic and backward compatible.
+
+## Proxy Chain Connection Accumulation Fix (v19.5.14+)
+
+### Issue
+When chaining SmartProxies (Client → SmartProxy1 → SmartProxy2 → Backend), connections would accumulate and never be cleaned up. This was particularly severe when the backend was down or closing connections immediately.
+
+### Root Cause
+The half-open connection support was preventing proper cascade cleanup in proxy chains:
+1. Backend closes → SmartProxy2's server socket closes
+2. SmartProxy2 keeps client socket open (half-open support)
+3. SmartProxy1 never gets notified that downstream is closed
+4. Connections accumulate at each proxy in the chain
+
+The issue was in `createIndependentSocketHandlers()` which waited for BOTH sockets to close before cleanup.
+
+### Solution
+1. **Changed default behavior**: When one socket closes, both close immediately
+2. **Made half-open support opt-in**: Only enabled when explicitly requested
+3. **Centralized socket handling**: Created `setupBidirectionalForwarding()` for consistent behavior
+4. **Applied everywhere**: Updated HttpProxyBridge and route-connection-handler to use centralized handling
+
+### Changes Made
+```typescript
+// socket-utils.ts - Default behavior now closes both sockets
+export function createIndependentSocketHandlers(
+  clientSocket, serverSocket, onBothClosed,
+  options: { enableHalfOpen?: boolean } = {} // Half-open is opt-in
+) {
+  // When server closes, immediately close client (unless half-open enabled)
+  if (!clientClosed && !options.enableHalfOpen) {
+    clientSocket.destroy();
+  }
+}
+
+// New centralized function for consistent socket pairing
+export function setupBidirectionalForwarding(
+  clientSocket, serverSocket,
+  handlers: {
+    onClientData?: (chunk) => void;
+    onServerData?: (chunk) => void;
+    onCleanup: (reason) => void;
+    enableHalfOpen?: boolean; // Default: false
+  }
+)
+```
+
+### Test Coverage
+- `test/test.proxy-chain-simple.node.ts` - Verifies proxy chains don't accumulate connections
+- Tests confirm connections stay at 0 even with backend closing immediately
+- Works for any proxy chain configuration (not just localhost)
+
+### Performance Impact
+- **Positive**: No more connection accumulation in proxy chains
+- **Positive**: Immediate cleanup reduces memory usage
+- **Neutral**: Half-open connections still available when needed (opt-in)
+
+### Migration Notes
+No configuration changes needed. The fix applies to all proxy chains automatically.
+
+## Socket Cleanup Handler Deprecation (v19.5.15+)
+
+### Issue
+The deprecated `createSocketCleanupHandler()` function was still being used in forwarding handlers, despite being marked as deprecated.
+
+### Solution
+Updated all forwarding handlers to use the new centralized socket utilities:
+1. **Replaced `createSocketCleanupHandler()`** with `setupBidirectionalForwarding()` in:
+   - `https-terminate-to-https-handler.ts`
+   - `https-terminate-to-http-handler.ts`
+2. **Removed deprecated function** from `socket-utils.ts`
+
+### Benefits
+- Consistent socket handling across all handlers
+- Proper cleanup in proxy chains (no half-open connections by default)
+- Better backpressure handling with the centralized implementation
+- Reduced code duplication
+
+### Migration Notes
+No user-facing changes. All forwarding handlers now use the same robust socket handling as the main SmartProxy connection handler.
+
+## WrappedSocket Class Evaluation for PROXY Protocol (v19.5.19+)
+
+### Current Socket Handling Architecture
+- Sockets are handled directly as `net.Socket` instances throughout the codebase
+- Socket augmentation via TypeScript module augmentation for TLS properties
+- Metadata tracked separately in `IConnectionRecord` objects
+- Socket utilities provide helper functions but don't encapsulate the socket
+- Connection records track extensive metadata (IDs, timestamps, byte counters, TLS state, etc.)
+
+### Evaluation: Should We Introduce a WrappedSocket Class?
+
+**Yes, a WrappedSocket class would make sense**, particularly for PROXY protocol implementation and future extensibility.
+
+### Design Considerations for WrappedSocket
+
+```typescript
+class WrappedSocket {
+  private socket: net.Socket;
+  private connectionId: string;
+  private metadata: {
+    realClientIP?: string;     // From PROXY protocol
+    realClientPort?: number;   // From PROXY protocol
+    proxyIP?: string;          // Immediate connection IP
+    proxyPort?: number;        // Immediate connection port
+    bytesReceived: number;
+    bytesSent: number;
+    lastActivity: number;
+    isTLS: boolean;
+    // ... other metadata
+  };
+  
+  // PROXY protocol handling
+  private proxyProtocolParsed: boolean = false;
+  private pendingData: Buffer[] = [];
+  
+  constructor(socket: net.Socket) {
+    this.socket = socket;
+    this.setupHandlers();
+  }
+  
+  // Getters for clean access
+  get remoteAddress(): string {
+    return this.metadata.realClientIP || this.socket.remoteAddress || '';
+  }
+  
+  get remotePort(): number {
+    return this.metadata.realClientPort || this.socket.remotePort || 0;
+  }
+  
+  get isFromTrustedProxy(): boolean {
+    return !!this.metadata.realClientIP;
+  }
+  
+  // PROXY protocol parsing
+  async parseProxyProtocol(trustedProxies: string[]): Promise<boolean> {
+    // Implementation here
+  }
+  
+  // Delegate socket methods
+  write(data: any): boolean {
+    this.metadata.bytesSent += Buffer.byteLength(data);
+    return this.socket.write(data);
+  }
+  
+  destroy(error?: Error): void {
+    this.socket.destroy(error);
+  }
+  
+  // Event forwarding
+  on(event: string, listener: Function): this {
+    this.socket.on(event, listener);
+    return this;
+  }
+}
+```
+
+### Implementation Benefits
+
+1. **Encapsulation**: Bundle socket + metadata + behavior in one place
+2. **PROXY Protocol Integration**: Cleaner handling without modifying existing socket code
+3. **State Management**: Centralized socket state tracking and validation
+4. **API Consistency**: Uniform interface for all socket operations
+5. **Future Extensibility**: Easy to add new socket-level features (compression, encryption, etc.)
+6. **Type Safety**: Better TypeScript support without module augmentation
+7. **Testing**: Easier to mock and test socket behavior
+
+### Implementation Drawbacks
+
+1. **Major Refactoring**: Would require changes throughout the codebase
+2. **Performance Overhead**: Additional abstraction layer (minimal but present)
+3. **Compatibility**: Need to maintain event emitter compatibility
+4. **Learning Curve**: Developers need to understand the wrapper
+
+### Recommended Approach: Phased Implementation
+
+**Phase 1: PROXY Protocol Only** (Immediate)
+- Create minimal `ProxyProtocolSocket` wrapper for new connections from trusted proxies
+- Use in connection handler when receiving from trusted proxy IPs
+- Minimal disruption to existing code
+
+```typescript
+class ProxyProtocolSocket {
+  constructor(
+    public socket: net.Socket,
+    public realClientIP?: string,
+    public realClientPort?: number
+  ) {}
+  
+  get remoteAddress(): string {
+    return this.realClientIP || this.socket.remoteAddress || '';
+  }
+  
+  get remotePort(): number {
+    return this.realClientPort || this.socket.remotePort || 0;
+  }
+}
+```
+
+**Phase 2: Gradual Migration** (Future)
+- Extend wrapper with more functionality
+- Migrate critical paths to use wrapper
+- Add performance monitoring
+
+**Phase 3: Full Adoption** (Long-term)
+- Complete migration to WrappedSocket
+- Remove socket augmentation
+- Standardize all socket handling
+
+### Decision Summary
+
+✅ **Implement minimal ProxyProtocolSocket for immediate PROXY protocol support**
+- Low risk, high value
+- Solves the immediate proxy chain connection limit issue
+- Sets foundation for future improvements
+- Can be implemented alongside existing code
+
+📋 **Consider full WrappedSocket for future major version**
+- Cleaner architecture
+- Better maintainability
+- But requires significant refactoring

+# PROXY Protocol Implementation Plan
+
+## Overview
+Implement PROXY protocol support in SmartProxy to preserve client IP information through proxy chains, solving the connection limit accumulation issue where inner proxies see all connections as coming from the outer proxy's IP.
+
+## Problem Statement
+- In proxy chains, the inner proxy sees all connections from the outer proxy's IP
+- This causes the inner proxy to hit per-IP connection limits (default: 100)
+- Results in connection rejections while outer proxy accumulates connections
+
+## Solution Design
+
+### 1. Core Features
+
+#### 1.1 PROXY Protocol Parsing
+- Support PROXY protocol v1 (text format) initially
+- Parse incoming PROXY headers to extract:
+  - Real client IP address
+  - Real client port
+  - Proxy IP address
+  - Proxy port
+  - Protocol (TCP4/TCP6)
+
+#### 1.2 PROXY Protocol Generation
+- Add ability to send PROXY protocol headers when forwarding connections
+- Configurable per route or target
+
+#### 1.3 Trusted Proxy IPs
+- New `proxyIPs` array in SmartProxy options
+- Auto-enable PROXY protocol acceptance for connections from these IPs
+- Reject PROXY protocol from untrusted sources (security)
+
+### 2. Configuration Schema
+
+```typescript
+interface ISmartProxyOptions {
+  // ... existing options
+  
+  // List of trusted proxy IPs that can send PROXY protocol
+  proxyIPs?: string[];
+  
+  // Global option to accept PROXY protocol (defaults based on proxyIPs)
+  acceptProxyProtocol?: boolean;
+  
+  // Global option to send PROXY protocol to all targets
+  sendProxyProtocol?: boolean;
+}
+
+interface IRouteAction {
+  // ... existing options
+  
+  // Send PROXY protocol to this specific target
+  sendProxyProtocol?: boolean;
+}
+```
+
+### 3. Implementation Steps
+
+#### Phase 1: WrappedSocket Foundation
+1. Create minimal `ProxyProtocolSocket` class in `ts/core/models/proxy-protocol-socket.ts`
+2. Implement basic socket wrapper with real IP getters
+3. Update `ConnectionManager` to accept wrapped sockets
+4. Create tests for wrapped socket functionality
+
+#### Phase 2: PROXY Protocol Parser
+1. Create `ProxyProtocolParser` class in `ts/core/utils/proxy-protocol.ts`
+2. Implement v1 text format parsing
+3. Add validation and error handling
+4. Integrate parser into ProxyProtocolSocket
+
+#### Phase 3: Connection Handler Integration
+1. Modify `RouteConnectionHandler` to use ProxyProtocolSocket for trusted IPs
+2. Parse PROXY header before TLS detection
+3. Use wrapped socket throughout connection lifecycle
+4. Strip PROXY header before forwarding data
+
+#### Phase 4: Outbound PROXY Protocol
+1. Add PROXY header generation in `setupDirectConnection`
+2. Make it configurable per route
+3. Send header immediately after TCP connection
+4. Use ProxyProtocolSocket for outbound connections too
+
+#### Phase 5: Security & Validation
+1. Validate PROXY headers strictly
+2. Reject malformed headers
+3. Only accept from trusted IPs
+4. Add rate limiting for PROXY protocol parsing
+
+### 4. Design Decision: Socket Wrapper Architecture
+
+#### Option A: Minimal Single Socket Wrapper
+- **Scope**: Wraps individual sockets with metadata
+- **Use Case**: PROXY protocol support with minimal refactoring
+- **Pros**: Simple, low risk, easy migration
+- **Cons**: Still need separate connection management
+
+#### Option B: Comprehensive Connection Wrapper
+- **Scope**: Manages socket pairs (incoming + outgoing) with all utilities
+- **Use Case**: Complete connection lifecycle management
+- **Pros**: 
+  - Encapsulates all socket utilities (forwarding, cleanup, backpressure)
+  - Single object represents entire connection
+  - Cleaner API for connection handling
+- **Cons**: 
+  - Major architectural change
+  - Higher implementation risk
+  - More complex migration
+
+#### Recommendation
+Start with **Option A** (ProxyProtocolSocket) for immediate PROXY protocol support, then evaluate Option B based on:
+- Performance impact of additional abstraction
+- Code simplification benefits
+- Team comfort with architectural change
+
+### 5. Code Changes (Using Option A Initially)
+
+#### 5.1 ProxyProtocolSocket (new file)
+```typescript
+// ts/core/models/proxy-protocol-socket.ts
+export class ProxyProtocolSocket {
+  constructor(
+    public readonly socket: plugins.net.Socket,
+    private realClientIP?: string,
+    private realClientPort?: number
+  ) {}
+  
+  get remoteAddress(): string {
+    return this.realClientIP || this.socket.remoteAddress || '';
+  }
+  
+  get remotePort(): number {
+    return this.realClientPort || this.socket.remotePort || 0;
+  }
+  
+  get isFromTrustedProxy(): boolean {
+    return !!this.realClientIP;
+  }
+  
+  setProxyInfo(ip: string, port: number): void {
+    this.realClientIP = ip;
+    this.realClientPort = port;
+  }
+}
+```
+
+#### 4.2 ProxyProtocolParser (new file)
+```typescript
+// ts/core/utils/proxy-protocol.ts
+export class ProxyProtocolParser {
+  static readonly PROXY_V1_SIGNATURE = 'PROXY ';
+  
+  static parse(chunk: Buffer): IProxyInfo | null {
+    // Implementation
+  }
+  
+  static generate(info: IProxyInfo): Buffer {
+    // Implementation
+  }
+}
+```
+
+#### 4.3 Connection Handler Updates
+```typescript
+// In handleConnection method
+let wrappedSocket: ProxyProtocolSocket | plugins.net.Socket = socket;
+
+// Wrap socket if from trusted proxy
+if (this.settings.proxyIPs?.includes(socket.remoteAddress)) {
+  wrappedSocket = new ProxyProtocolSocket(socket);
+}
+
+// Create connection record with wrapped socket
+const record = this.connectionManager.createConnection(wrappedSocket);
+
+// In handleInitialData method
+if (wrappedSocket instanceof ProxyProtocolSocket) {
+  const proxyInfo = await this.checkForProxyProtocol(chunk);
+  if (proxyInfo) {
+    wrappedSocket.setProxyInfo(proxyInfo.sourceIP, proxyInfo.sourcePort);
+    // Continue with remaining data after PROXY header
+  }
+}
+```
+
+#### 4.4 Security Manager Updates
+- Accept socket or ProxyProtocolSocket
+- Use `socket.remoteAddress` getter for real client IP
+- Transparent handling of both socket types
+
+### 5. Configuration Examples
+
+#### Basic Setup
+```typescript
+// Outer proxy - sends PROXY protocol
+const outerProxy = new SmartProxy({
+  ports: [443],
+  routes: [{
+    name: 'to-inner-proxy',
+    match: { ports: 443 },
+    action: {
+      type: 'forward',
+      target: { host: '195.201.98.232', port: 443 },
+      sendProxyProtocol: true  // Enable for this route
+    }
+  }]
+});
+
+// Inner proxy - accepts PROXY protocol from outer proxy
+const innerProxy = new SmartProxy({
+  ports: [443],
+  proxyIPs: ['212.95.99.130'],  // Outer proxy IP
+  // acceptProxyProtocol: true is automatic for proxyIPs
+  routes: [{
+    name: 'to-backend',
+    match: { ports: 443 },
+    action: {
+      type: 'forward',
+      target: { host: '192.168.5.247', port: 443 }
+    }
+  }]
+});
+```
+
+### 6. Testing Plan
+
+#### Unit Tests
+- PROXY protocol v1 parsing (valid/invalid formats)
+- Header generation
+- Trusted IP validation
+- Connection record updates
+
+#### Integration Tests
+- Single proxy with PROXY protocol
+- Proxy chain with PROXY protocol
+- Security: reject from untrusted IPs
+- Performance: minimal overhead
+- Compatibility: works with TLS passthrough
+
+#### Test Scenarios
+1. **Connection limit test**: Verify inner proxy sees real client IPs
+2. **Security test**: Ensure PROXY protocol rejected from untrusted sources
+3. **Compatibility test**: Verify no impact on non-PROXY connections
+4. **Performance test**: Measure overhead of PROXY protocol parsing
+
+### 7. Security Considerations
+
+1. **IP Spoofing Prevention**
+   - Only accept PROXY protocol from explicitly trusted IPs
+   - Validate all header fields
+   - Reject malformed headers immediately
+
+2. **Resource Protection**
+   - Limit PROXY header size (107 bytes for v1)
+   - Timeout for incomplete headers
+   - Rate limit connection attempts
+
+3. **Logging**
+   - Log all PROXY protocol acceptance/rejection
+   - Include real client IP in all connection logs
+
+### 8. Rollout Strategy
+
+1. **Phase 1**: Deploy parser and acceptance (backward compatible)
+2. **Phase 2**: Enable between controlled proxy pairs
+3. **Phase 3**: Monitor for issues and performance impact
+4. **Phase 4**: Expand to all proxy chains
+
+### 9. Success Metrics
+
+- Inner proxy connection distribution matches outer proxy
+- No more connection limit rejections in proxy chains
+- Accurate client IP logging throughout the chain
+- No performance degradation (<1ms added latency)
+
+### 10. Future Enhancements
+
+- PROXY protocol v2 (binary format) support
+- TLV extensions for additional metadata
+- AWS VPC endpoint ID support
+- Custom metadata fields
+
+## WrappedSocket Class Design
+
+### Overview
+A WrappedSocket class has been evaluated and recommended to provide cleaner PROXY protocol integration and better socket management architecture.
+
+### Rationale for WrappedSocket
+
+#### Current Challenges
+- Sockets handled directly as `net.Socket` instances throughout codebase
+- Metadata tracked separately in `IConnectionRecord` objects
+- Socket augmentation via TypeScript module augmentation for TLS properties
+- PROXY protocol would require modifying socket handling in multiple places
+
+#### Benefits
+1. **Clean PROXY Protocol Integration** - Parse and store real client IP/port without modifying existing socket handling
+2. **Better Encapsulation** - Bundle socket + metadata + behavior together
+3. **Type Safety** - No more module augmentation needed
+4. **Future Extensibility** - Easy to add compression, metrics, etc.
+5. **Simplified Testing** - Easier to mock and test socket behavior
+
+### Implementation Strategy
+
+#### Phase 1: Minimal ProxyProtocolSocket (Immediate)
+Create a minimal wrapper for PROXY protocol support:
+
+```typescript
+class ProxyProtocolSocket {
+  constructor(
+    public socket: net.Socket,
+    public realClientIP?: string,
+    public realClientPort?: number
+  ) {}
+  
+  get remoteAddress(): string {
+    return this.realClientIP || this.socket.remoteAddress || '';
+  }
+  
+  get remotePort(): number {
+    return this.realClientPort || this.socket.remotePort || 0;
+  }
+  
+  get isFromTrustedProxy(): boolean {
+    return !!this.realClientIP;
+  }
+}
+```
+
+Integration points:
+- Use in `RouteConnectionHandler` when receiving from trusted proxy IPs
+- Update `ConnectionManager` to accept wrapped sockets
+- Modify security checks to use `socket.remoteAddress` getter
+
+#### Phase 2: Connection-Aware WrappedSocket (Alternative Design)
+A more comprehensive design that manages both sides of a connection:
+
+```typescript
+// Option A: Single Socket Wrapper (simpler)
+class WrappedSocket extends EventEmitter {
+  private socket: net.Socket;
+  private connectionId: string;
+  private metadata: ISocketMetadata;
+  
+  constructor(socket: net.Socket, metadata?: Partial<ISocketMetadata>) {
+    super();
+    this.socket = socket;
+    this.connectionId = this.generateId();
+    this.metadata = { ...defaultMetadata, ...metadata };
+    this.setupHandlers();
+  }
+  
+  // ... single socket management
+}
+
+// Option B: Connection Pair Wrapper (comprehensive)
+class WrappedConnection extends EventEmitter {
+  private connectionId: string;
+  private incoming: WrappedSocket;
+  private outgoing?: WrappedSocket;
+  private forwardingActive: boolean = false;
+  
+  constructor(incomingSocket: net.Socket) {
+    super();
+    this.connectionId = this.generateId();
+    this.incoming = new WrappedSocket(incomingSocket);
+  }
+  
+  // Connect to backend and set up forwarding
+  async connectToBackend(target: ITarget): Promise<void> {
+    const outgoingSocket = await this.createOutgoingConnection(target);
+    this.outgoing = new WrappedSocket(outgoingSocket);
+    await this.setupBidirectionalForwarding();
+  }
+  
+  // Built-in forwarding logic from socket-utils
+  private async setupBidirectionalForwarding(): Promise<void> {
+    if (!this.outgoing) throw new Error('No outgoing socket');
+    
+    // Handle data forwarding with backpressure
+    this.incoming.on('data', (chunk) => {
+      this.outgoing!.write(chunk, () => {
+        // Handle backpressure
+      });
+    });
+    
+    this.outgoing.on('data', (chunk) => {
+      this.incoming.write(chunk, () => {
+        // Handle backpressure
+      });
+    });
+    
+    // Handle connection lifecycle
+    const cleanup = (reason: string) => {
+      this.forwardingActive = false;
+      this.incoming.destroy();
+      this.outgoing?.destroy();
+      this.emit('closed', reason);
+    };
+    
+    this.incoming.once('close', () => cleanup('incoming_closed'));
+    this.outgoing.once('close', () => cleanup('outgoing_closed'));
+    
+    this.forwardingActive = true;
+  }
+  
+  // PROXY protocol support
+  async handleProxyProtocol(trustedProxies: string[]): Promise<boolean> {
+    if (trustedProxies.includes(this.incoming.socket.remoteAddress)) {
+      const parsed = await this.incoming.parseProxyProtocol();
+      if (parsed && this.outgoing) {
+        // Forward PROXY protocol to backend if configured
+        await this.outgoing.sendProxyProtocol(this.incoming.realClientIP);
+      }
+      return parsed;
+    }
+    return false;
+  }
+  
+  // Consolidated metrics
+  getMetrics(): IConnectionMetrics {
+    return {
+      connectionId: this.connectionId,
+      duration: Date.now() - this.startTime,
+      incoming: this.incoming.getMetrics(),
+      outgoing: this.outgoing?.getMetrics(),
+      totalBytes: this.getTotalBytes(),
+      state: this.getConnectionState()
+    };
+  }
+}
+```
+
+#### Phase 3: Full Migration (Long-term)
+- Replace all `net.Socket` usage with `WrappedSocket`
+- Remove socket augmentation from `socket-augmentation.ts`
+- Update all socket utilities to work with wrapped sockets
+- Standardize socket handling across all components
+
+### Integration with PROXY Protocol
+
+The WrappedSocket class integrates seamlessly with PROXY protocol:
+
+1. **Connection Acceptance**:
+   ```typescript
+   const wrappedSocket = new ProxyProtocolSocket(socket);
+   if (this.isFromTrustedProxy(socket.remoteAddress)) {
+     await wrappedSocket.parseProxyProtocol(this.settings.proxyIPs);
+   }
+   ```
+
+2. **Security Checks**:
+   ```typescript
+   // Automatically uses real client IP if available
+   const clientIP = wrappedSocket.remoteAddress;
+   if (!this.securityManager.isIPAllowed(clientIP)) {
+     wrappedSocket.destroy();
+   }
+   ```
+
+3. **Connection Records**:
+   ```typescript
+   const record = this.connectionManager.createConnection(wrappedSocket);
+   // ConnectionManager uses wrappedSocket.remoteAddress transparently
+   ```
+
+### Option B Example: How It Would Replace Current Architecture
+
+Instead of current approach with separate components:
+```typescript
+// Current: Multiple separate components
+const record = connectionManager.createConnection(socket);
+const { cleanupClient, cleanupServer } = createIndependentSocketHandlers(
+  clientSocket, serverSocket, onBothClosed
+);
+setupBidirectionalForwarding(clientSocket, serverSocket, handlers);
+```
+
+Option B would consolidate everything:
+```typescript
+// Option B: Single connection object
+const connection = new WrappedConnection(incomingSocket);
+await connection.handleProxyProtocol(trustedProxies);
+await connection.connectToBackend({ host: 'server', port: 443 });
+// Everything is handled internally - forwarding, cleanup, metrics
+
+connection.on('closed', (reason) => {
+  logger.log('Connection closed', connection.getMetrics());
+});
+```
+
+This would replace:
+- `IConnectionRecord` - absorbed into WrappedConnection
+- `socket-utils.ts` functions - methods on WrappedConnection
+- Separate incoming/outgoing tracking - unified in one object
+- Manual cleanup coordination - automatic lifecycle management
+
+Additional benefits with Option B:
+- **Connection Pooling Integration**: WrappedConnection could integrate with EnhancedConnectionPool for backend connections
+- **Unified Metrics**: Single point for all connection statistics
+- **Protocol Negotiation**: Handle PROXY, TLS, HTTP/2 upgrade in one place
+- **Resource Management**: Automatic cleanup with LifecycleComponent pattern
+
+### Migration Path
+
+1. **Week 1-2**: Implement minimal ProxyProtocolSocket (Option A)
+2. **Week 3-4**: Test with PROXY protocol implementation
+3. **Month 2**: Prototype WrappedConnection (Option B) if beneficial
+4. **Month 3-6**: Gradual migration if Option B proves valuable
+5. **Future**: Complete adoption in next major version
+
+### Success Criteria
+
+- PROXY protocol works transparently with wrapped sockets
+- No performance regression (<0.1% overhead)
+- Simplified code in connection handlers
+- Better TypeScript type safety
+- Easier to add new socket-level features

+# SmartProxy Routing Architecture Unification Plan
+
+## Overview
+This document analyzes the current state of routing in SmartProxy, identifies redundancies and inconsistencies, and proposes a unified architecture.
+
+## Current State Analysis
+
+### 1. Multiple Route Manager Implementations
+
+#### 1.1 Core SharedRouteManager (`ts/core/utils/route-manager.ts`)
+- **Purpose**: Designed as a shared component for SmartProxy and NetworkProxy
+- **Features**:
+  - Port mapping and expansion (e.g., `[80, 443]` → individual routes)
+  - Comprehensive route matching (domain, path, IP, headers, TLS)
+  - Route validation and conflict detection
+  - Event emitter for route changes
+  - Detailed logging support
+- **Status**: Well-designed but underutilized
+
+#### 1.2 SmartProxy RouteManager (`ts/proxies/smart-proxy/route-manager.ts`)
+- **Purpose**: SmartProxy-specific route management
+- **Issues**:
+  - 95% duplicate code from SharedRouteManager
+  - Only difference is using `ISmartProxyOptions` instead of generic interface
+  - Contains deprecated security methods
+  - Unnecessary code duplication
+- **Status**: Should be removed in favor of SharedRouteManager
+
+#### 1.3 HttpProxy Route Management (`ts/proxies/http-proxy/`)
+- **Purpose**: HTTP-specific routing
+- **Implementation**: Minimal, inline route matching
+- **Status**: Could benefit from SharedRouteManager
+
+### 2. Multiple Router Implementations
+
+#### 2.1 ProxyRouter (`ts/routing/router/proxy-router.ts`)
+- **Purpose**: Legacy compatibility with `IReverseProxyConfig`
+- **Features**: Domain-based routing with path patterns
+- **Used by**: HttpProxy for backward compatibility
+
+#### 2.2 RouteRouter (`ts/routing/router/route-router.ts`)
+- **Purpose**: Modern routing with `IRouteConfig`
+- **Features**: Nearly identical to ProxyRouter
+- **Issues**: Code duplication with ProxyRouter
+
+### 3. Scattered Route Utilities
+
+#### 3.1 Core route-utils (`ts/core/utils/route-utils.ts`)
+- **Purpose**: Shared matching functions
+- **Features**: Domain, path, IP, CIDR matching
+- **Status**: Well-implemented, should be the single source
+
+#### 3.2 SmartProxy route-utils (`ts/proxies/smart-proxy/utils/route-utils.ts`)
+- **Purpose**: Route configuration utilities
+- **Features**: Different scope - config merging, not pattern matching
+- **Status**: Keep separate as it serves different purpose
+
+### 4. Other Route-Related Files
+- `route-patterns.ts`: Constants for route patterns
+- `route-validators.ts`: Route configuration validation
+- `route-helpers.ts`: Additional utilities
+- `route-connection-handler.ts`: Connection routing logic
+
+## Problems Identified
+
+### 1. Code Duplication
+- **SharedRouteManager vs SmartProxy RouteManager**: ~1000 lines of duplicate code
+- **ProxyRouter vs RouteRouter**: ~500 lines of duplicate code
+- **Matching logic**: Implemented in 4+ different places
+
+### 2. Inconsistent Implementations
+```typescript
+// Example: Domain matching appears in multiple places
+// 1. In route-utils.ts
+export function matchDomain(pattern: string, hostname: string): boolean
+
+// 2. In SmartProxy RouteManager
+private matchDomain(domain: string, hostname: string): boolean
+
+// 3. In ProxyRouter
+private matchesHostname(configName: string, hostname: string): boolean
+
+// 4. In RouteRouter
+private matchDomain(pattern: string, hostname: string): boolean
+```
+
+### 3. Unclear Separation of Concerns
+- Route Managers handle both storage AND matching
+- Routers also handle storage AND matching
+- No clear boundaries between layers
+
+### 4. Maintenance Burden
+- Bug fixes need to be applied in multiple places
+- New features must be implemented multiple times
+- Testing effort multiplied
+
+## Proposed Unified Architecture
+
+### Layer 1: Core Routing Components
+```
+ts/core/routing/
+├── types.ts              # All route-related types
+├── utils.ts              # All matching logic (consolidated)
+├── route-store.ts        # Route storage and indexing
+└── route-matcher.ts      # Route matching engine
+```
+
+### Layer 2: Route Management
+```
+ts/core/routing/
+└── route-manager.ts      # Single RouteManager for all proxies
+    - Uses RouteStore for storage
+    - Uses RouteMatcher for matching
+    - Provides high-level API
+```
+
+### Layer 3: HTTP Routing
+```
+ts/routing/
+└── http-router.ts        # Single HTTP router implementation
+    - Uses RouteManager for route lookup
+    - Handles HTTP-specific concerns
+    - Legacy adapter built-in
+```
+
+### Layer 4: Proxy Integration
+```
+ts/proxies/
+├── smart-proxy/
+│   └── (uses core RouteManager directly)
+├── http-proxy/
+│   └── (uses core RouteManager + HttpRouter)
+└── network-proxy/
+    └── (uses core RouteManager directly)
+```
+
+## Implementation Plan
+
+### Phase 1: Consolidate Matching Logic (Week 1)
+1. **Audit all matching implementations**
+   - Document differences in behavior
+   - Identify the most comprehensive implementation
+   - Create test suite covering all edge cases
+
+2. **Create unified matching module**
+   ```typescript
+   // ts/core/routing/matchers.ts
+   export class DomainMatcher {
+     static match(pattern: string, hostname: string): boolean
+   }
+   
+   export class PathMatcher {
+     static match(pattern: string, path: string): MatchResult
+   }
+   
+   export class IpMatcher {
+     static match(pattern: string, ip: string): boolean
+     static matchCidr(cidr: string, ip: string): boolean
+   }
+   ```
+
+3. **Update all components to use unified matchers**
+   - Replace local implementations
+   - Ensure backward compatibility
+   - Run comprehensive tests
+
+### Phase 2: Unify Route Managers (Week 2)
+1. **Enhance SharedRouteManager**
+   - Add any missing features from SmartProxy RouteManager
+   - Make it truly generic (no proxy-specific dependencies)
+   - Add adapter pattern for different options types
+
+2. **Migrate SmartProxy to use SharedRouteManager**
+   ```typescript
+   // Before
+   this.routeManager = new RouteManager(this.settings);
+   
+   // After
+   this.routeManager = new SharedRouteManager({
+     logger: this.settings.logger,
+     enableDetailedLogging: this.settings.enableDetailedLogging
+   });
+   ```
+
+3. **Remove duplicate RouteManager**
+   - Delete `ts/proxies/smart-proxy/route-manager.ts`
+   - Update all imports
+   - Verify all tests pass
+
+### Phase 3: Consolidate Routers (Week 3)
+1. **Create unified HttpRouter**
+   ```typescript
+   export class HttpRouter {
+     constructor(private routeManager: SharedRouteManager) {}
+     
+     // Modern interface
+     route(req: IncomingMessage): RouteResult
+     
+     // Legacy adapter
+     routeLegacy(config: IReverseProxyConfig): RouteResult
+   }
+   ```
+
+2. **Migrate HttpProxy**
+   - Replace both ProxyRouter and RouteRouter
+   - Use single HttpRouter with appropriate adapter
+   - Maintain backward compatibility
+
+3. **Clean up legacy code**
+   - Mark old interfaces as deprecated
+   - Add migration guides
+   - Plan removal in next major version
+
+### Phase 4: Architecture Cleanup (Week 4)
+1. **Reorganize file structure**
+   ```
+   ts/core/
+   ├── routing/
+   │   ├── index.ts
+   │   ├── types.ts
+   │   ├── matchers/
+   │   │   ├── domain.ts
+   │   │   ├── path.ts
+   │   │   ├── ip.ts
+   │   │   └── index.ts
+   │   ├── route-store.ts
+   │   ├── route-matcher.ts
+   │   └── route-manager.ts
+   └── utils/
+       └── (remove route-specific utils)
+   ```
+
+2. **Update documentation**
+   - Architecture diagrams
+   - Migration guides
+   - API documentation
+
+3. **Performance optimization**
+   - Add caching where beneficial
+   - Optimize hot paths
+   - Benchmark before/after
+
+## Migration Strategy
+
+### For SmartProxy RouteManager Users
+```typescript
+// Old way
+import { RouteManager } from './route-manager.js';
+const manager = new RouteManager(options);
+
+// New way
+import { SharedRouteManager as RouteManager } from '../core/utils/route-manager.js';
+const manager = new RouteManager({
+  logger: options.logger,
+  enableDetailedLogging: options.enableDetailedLogging
+});
+```
+
+### For Router Users
+```typescript
+// Old way
+const proxyRouter = new ProxyRouter();
+const routeRouter = new RouteRouter();
+
+// New way
+const router = new HttpRouter(routeManager);
+// Automatically handles both modern and legacy configs
+```
+
+## Success Metrics
+
+1. **Code Reduction**
+   - Target: Remove ~1,500 lines of duplicate code
+   - Measure: Lines of code before/after
+
+2. **Performance**
+   - Target: No regression in routing performance
+   - Measure: Benchmark route matching operations
+
+3. **Maintainability**
+   - Target: Single implementation for each concept
+   - Measure: Time to implement new features
+
+4. **Test Coverage**
+   - Target: 100% coverage of routing logic
+   - Measure: Coverage reports
+
+## Risks and Mitigations
+
+### Risk 1: Breaking Changes
+- **Mitigation**: Extensive adapter patterns and backward compatibility layers
+- **Testing**: Run all existing tests plus new integration tests
+
+### Risk 2: Performance Regression
+- **Mitigation**: Benchmark critical paths before changes
+- **Testing**: Load testing with production-like scenarios
+
+### Risk 3: Hidden Dependencies
+- **Mitigation**: Careful code analysis and dependency mapping
+- **Testing**: Integration tests across all proxy types
+
+## Long-term Vision
+
+### Future Enhancements
+1. **Route Caching**: LRU cache for frequently accessed routes
+2. **Route Indexing**: Trie-based indexing for faster domain matching
+3. **Route Priorities**: Explicit priority system instead of specificity
+4. **Dynamic Routes**: Support for runtime route modifications
+5. **Route Templates**: Reusable route configurations
+
+### API Evolution
+```typescript
+// Future unified routing API
+const routingEngine = new RoutingEngine({
+  stores: [fileStore, dbStore, dynamicStore],
+  matchers: [domainMatcher, pathMatcher, customMatcher],
+  cache: new LRUCache({ max: 1000 }),
+  indexes: {
+    domain: new TrieIndex(),
+    path: new RadixTree()
+  }
+});
+
+// Simple, powerful API
+const route = await routingEngine.findRoute({
+  domain: 'example.com',
+  path: '/api/v1/users',
+  ip: '192.168.1.1',
+  headers: { 'x-custom': 'value' }
+});
+```
+
+## Conclusion
+
+The current routing architecture has significant duplication and inconsistencies. By following this unification plan, we can:
+1. Reduce code by ~30%
+2. Improve maintainability
+3. Ensure consistent behavior
+4. Enable future enhancements
+
+The phased approach minimizes risk while delivering incremental value. Each phase is independently valuable and can be deployed separately.
