+- Introduce new file ts/http/port80/acme-interfaces.ts defining SmartAcme interfaces, ICertManager, Http01MemoryHandler, and related types.
+- Refactor ts/http/port80/challenge-responder.ts to import types from acme-interfaces and improve event forwarding for certificate events.
+- Update readme.plan.md to reflect migration of Port80Handler and addition of ACME interfaces.
+
+## 2025-05-09 - 12.1.0 - feat(smartproxy)
+Migrate internal module paths and update HTTP/ACME components for SmartProxy

+
+## 2025-05-09 - 12.0.0 - BREAKING CHANGE(forwarding)
+Rename 'sniPassthrough' export to 'httpsPassthrough' for consistent naming and remove outdated forwarding example
+
+- Updated test files (test.forwarding.ts and test.forwarding.unit.ts) to reference 'httpsPassthrough' instead of the old alias 'sniPassthrough'
+- Modified ts/smartproxy/forwarding/index.ts to export 'httpsPassthrough' without the legacy alias
+- Removed ts/examples/forwarding-example.ts to clean up redundant example code
+
+## 2025-05-09 - 11.0.0 - BREAKING CHANGE(forwarding)
+Refactor unified forwarding API and remove redundant documentation. Removed docs/forwarding-system.md (its content is migrated into readme.md) and updated helper functions (e.g. replacing sniPassthrough with httpsPassthrough) to accept configuration objects. Legacy fields in domain configurations (allowedIPs, blockedIPs, useNetworkProxy, networkProxyPort, connectionTimeout) have been removed in favor of forwarding.security and advanced options. Tests and examples have been updated accordingly.
+
+- Removed docs/forwarding-system.md; forwarding system docs now reside in readme.md.
+- Updated helper functions (httpOnly, tlsTerminateToHttp, tlsTerminateToHttps, httpsPassthrough) to accept object parameters rather than individual arguments.
+- Removed legacy domain configuration properties, shifting IP filtering to the forwarding.security field.
+- Adjusted return types and API contracts for certificate provisioning and SNI handling in the unified forwarding system.
+- Updated tests and examples to align with the new configuration interface.
+
+## 2025-05-09 - 10.3.0 - feat(forwarding)
+Add unified forwarding system docs and tests; update build script and .gitignore
+
+- Added docs/forwarding-system.md documenting the new unified forwarding system architecture, configuration, and usage examples
+- Updated .gitignore to exclude .claude/ directory

+- Extended ts/index.ts export to include the forwarding module
+- Introduced new tests and unit tests for forwarding, network proxy, and certificate provisioning
+
+## 2025-05-05 - 10.2.0 - feat(CertificateManager)
+Implement on-demand certificate retrieval for missing SNI certificates. When no certificate is found for a TLS ClientHello, the system now automatically registers the domain with the Port80Handler to trigger ACME issuance and immediately falls back to using the default certificate to complete the handshake. Additionally, HTTP requests on port 80 for unrecognized domains now return a 503 indicating that certificate issuance is in progress.
+
+- In CertificateManager.handleSNI, if no certificate is cached, call port80Handler.addDomain to trigger on-demand provisioning.
+- Update Port80Handler.handleRequest to register unknown domains and return a 503 for ACME HTTP-01 challenge requests.
+- Emit observability events (e.g. certificateRequested) so dynamic certificate requests can be tracked.
+- Fallback to default SSL context to allow TLS handshake while certificate issuance is performed.
+- Update and extend unit and integration tests to verify the new on-demand certificate flow.
+
 ## 2025-05-05 - 10.1.0 - feat(smartproxy)
 Implement fallback to NetworkProxy on missing SNI and rename certProvider to certProvisionFunction in CertProvisioner

-## Quick Start
+## Quick Start with SmartProxy
+
+SmartProxy is the recommended way to use this library, providing a unified API for all proxy scenarios.
+
+```typescript
+import { SmartProxy, createDomainConfig, httpOnly, tlsTerminateToHttp, httpsPassthrough } from '@push.rocks/smartproxy';
+
+// Create a new SmartProxy instance with all your domain configurations in one place
+const proxy = new SmartProxy({
+  // Listen on port 443 for incoming connections
+  fromPort: 443,
+
+  // Configure domains and their forwarding rules
+  domainConfigs: [
+    // Basic HTTP forwarding for api.example.com
+    createDomainConfig('api.example.com', httpOnly({
+      target: { host: 'localhost', port: 3000 }
+    })),
+
+    // HTTPS termination with automatic Let's Encrypt certificates
+    createDomainConfig('secure.example.com', tlsTerminateToHttp({
+      target: { host: 'localhost', port: 8080 },
+      acme: {
+        enabled: true,
+        production: true
+      }
+    })),
+
+    // Multiple domains with wildcard support
+    createDomainConfig(['example.com', '*.example.com'], httpsPassthrough({
+      target: {
+        // Load balancing across multiple backend servers
+        host: ['192.168.1.10', '192.168.1.11'],
+        port: 443
+      },
+      security: {
+        // IP filtering for enhanced security
+        allowedIps: ['10.0.0.*', '192.168.1.*'],
+        blockedIps: ['1.2.3.4']
+      }
+    }))
+  ],
+
+  // Enable SNI-based routing
+  sniEnabled: true,
+
+  // Automatic Let's Encrypt integration
+  acme: {
+    enabled: true,
+    contactEmail: 'admin@example.com',
+    useProduction: true
+  }
+});
+
+// Listen for certificate events
+proxy.on('certificate', evt => {
+  console.log(`Certificate for ${evt.domain} ready, expires: ${evt.expiryDate}`);
+});
+
+// Start the proxy
+await proxy.start();
+
+// Dynamically add or update domain configurations later
+await proxy.updateDomainConfigs([
+  createDomainConfig('new-domain.com', tlsTerminateToHttp({
+    target: { host: 'localhost', port: 9000 }
+  }))
+]);
+
+// Later, gracefully shut down
+await proxy.stop();
+```
+
+### What You Can Do with SmartProxy
+
+1. **Domain-Based Routing**
+   ```typescript
+   // Route requests for different domains to different backend servers
+   createDomainConfig('api.example.com', httpOnly({
+     target: { host: 'api-server', port: 3000 }
+   }))
+   ```
+
+2. **Automatic SSL with Let's Encrypt**
+   ```typescript
+   // Get and automatically renew certificates
+   createDomainConfig('secure.example.com', tlsTerminateToHttp({
+     target: { host: 'localhost', port: 8080 },
+     acme: { enabled: true, production: true }
+   }))
+   ```
+
+3. **Load Balancing**
+   ```typescript
+   // Distribute traffic across multiple backend servers
+   createDomainConfig('app.example.com', httpOnly({
+     target: {
+       host: ['10.0.0.1', '10.0.0.2', '10.0.0.3'],
+       port: 8080
+     }
+   }))
+   ```
+
+4. **Security Controls**
+   ```typescript
+   // Restrict access based on IP addresses
+   createDomainConfig('admin.example.com', httpOnly({
+     target: { host: 'localhost', port: 8080 },
+     security: {
+       allowedIps: ['10.0.0.*', '192.168.1.*'],
+       maxConnections: 100
+     }
+   }))
+   ```
+
+5. **Wildcard Domains**
+   ```typescript
+   // Handle all subdomains with one config
+   createDomainConfig(['example.com', '*.example.com'], httpsPassthrough({
+     target: { host: 'backend-server', port: 443 }
+   }))
+   ```
+
+## Other Components
+
+While SmartProxy provides a unified API for most needs, you can also use individual components:
+
+### NetworkProxy
+For HTTP/HTTPS reverse proxy with TLS termination and WebSocket support:
 
-### 1. HTTP(S) Reverse Proxy (NetworkProxy)
 ```typescript
 import { NetworkProxy } from '@push.rocks/smartproxy';
+import * as fs from 'fs';
 
 const proxy = new NetworkProxy({ port: 443 });
 await proxy.start();
-
 await proxy.updateProxyConfigs([

-await proxy.addDefaultHeaders({
-  'Strict-Transport-Security': 'max-age=31536000; includeSubDomains'
-});
-// ...
-await proxy.stop();
 ```
 
-### 2. HTTP→HTTPS Redirect (Redirect / SslRedirect)
-```typescript
-import { Redirect, SslRedirect } from '@push.rocks/smartproxy';
-import * as fs from 'fs';
+### Port80Handler
+For standalone ACME certificate management:
 
-// Custom redirect rules
-const redirect = new Redirect({
-  httpPort: 80,
-  httpsPort: 443,
-  sslOptions: {
-    key: fs.readFileSync('key.pem'),
-    cert: fs.readFileSync('cert.pem'),

-  ]
-});
-await redirect.start();
-
-// Quick HTTP→HTTPS helper on port 80
-const quick = new SslRedirect(80);
-await quick.start();
-```
-
-### 3. Automatic Certificates (ACME Port80Handler)
 ```typescript
 import { Port80Handler } from '@push.rocks/smartproxy';
 
-// Configure ACME on port 80 with contact email
 const acme = new Port80Handler({
   port: 80,
   contactEmail: 'admin@example.com',
-  useProduction: true,
-  renewThresholdDays: 30
-});
-acme.on('certificate-issued', evt => {
-  console.log(`Certificate ready for ${evt.domain}, expires ${evt.expiryDate}`);
+  useProduction: true
 });
+acme.on('certificate-issued', evt => console.log(`Certificate ready: ${evt.domain}`));
 await acme.start();
-acme.addDomain({
-  domainName: 'example.com',
-  sslRedirect: true,
-  acmeMaintenance: true
-});
 ```
 
-### 4. Low-Level Port Forwarding (NfTablesProxy)
+### NfTablesProxy
+For low-level port forwarding using nftables:
+
 ```typescript
 import { NfTablesProxy } from '@push.rocks/smartproxy';
 
-// Forward port 80→8080 with source IP preservation
 const nft = new NfTablesProxy({
   fromPort: 80,
   toPort: 8080,
   toHost: 'localhost',
-  preserveSourceIP: true,
-  deleteOnExit: true
+  preserveSourceIP: true
 });
 await nft.start();
-// ...
-await nft.stop();
 ```
 
-### 5. TCP/SNI Proxy (SmartProxy)
+### Redirect / SslRedirect
+For HTTP-to-HTTPS redirects:
+
 ```typescript
-import { SmartProxy } from '@push.rocks/smartproxy';
+import { SslRedirect } from '@push.rocks/smartproxy';
 
-const smart = new SmartProxy({
-  fromPort: 443,
-  toPort: 8443,
-  domainConfigs: [
-    {
-      domains: ['example.com', '*.example.com'],
-      allowedIPs: ['*'],
-      targetIPs: ['127.0.0.1'],
-    }
-  ],
-  sniEnabled: true
-});
-smart.on('certificate', evt => console.log(evt));
-await smart.start();
-// Update domains later
-await smart.updateDomainConfigs([/* new configs */]);
-```
-
-### 6. SNI Utilities (SniHandler)
-```js
-import { SniHandler } from '@push.rocks/smartproxy';
-
-// Extract SNI from a TLS ClientHello buffer
-const sni = SniHandler.extractSNI(buffer);
-
-// Reassemble fragmented ClientHello
-const complete = SniHandler.handleFragmentedClientHello(buf, connId);
+// Quick HTTP→HTTPS helper on port 80
+const redirect = new SslRedirect(80);
+await redirect.start();

+
+The SmartProxy component offers a clean, unified approach to handle virtually any proxy scenario.
+
+### 1. API Gateway / Backend Routing
+
+Create a flexible API gateway to route traffic to different microservices based on domain:
+
+```typescript
+import { SmartProxy, createDomainConfig, httpOnly, tlsTerminateToHttp } from '@push.rocks/smartproxy';
+
+const apiGateway = new SmartProxy({
+  fromPort: 443,
+  domainConfigs: [

+    createDomainConfig('users.api.example.com', tlsTerminateToHttp({
+      target: { host: 'users-service', port: 3000 },
+      acme: { enabled: true, production: true }
+    })),

+```
+
+### 2. Automatic HTTPS for Development
+
+Easily add HTTPS to your local development environment with automatic certificates:
+
+```typescript
+import { SmartProxy, createDomainConfig, tlsTerminateToHttp } from '@push.rocks/smartproxy';
+
+const devProxy = new SmartProxy({
+  fromPort: 443,
+  domainConfigs: [
+    createDomainConfig('dev.local', tlsTerminateToHttp({
+      target: { host: 'localhost', port: 3000 },
+      // For development, use self-signed or existing certificates
+      https: {
+        customCert: {
+          key: fs.readFileSync('dev-cert.key', 'utf8'),
+          cert: fs.readFileSync('dev-cert.pem', 'utf8')
+        }
+      },
+      // Auto-redirect HTTP to HTTPS
+      http: {
+        enabled: true,
+        redirectToHttps: true
+      }
+    }))
+  ]
+});
+
+await devProxy.start();
+```
+
+### 3. Load Balancing Multiple Servers
+
+Distribute traffic across multiple backend servers with round-robin load balancing:
+
+```typescript
+import { SmartProxy, createDomainConfig, tlsTerminateToHttp } from '@push.rocks/smartproxy';
+
+const loadBalancer = new SmartProxy({
+  fromPort: 443,
+  domainConfigs: [
+    createDomainConfig('app.example.com', tlsTerminateToHttp({
+      target: {
+        // Round-robin across multiple servers
+        host: [
+          '10.0.0.10',
+          '10.0.0.11',
+          '10.0.0.12'
+        ],
+        port: 8080
+      },
+      acme: { enabled: true, production: true }
+    }))
+  ]
+});
+
+await loadBalancer.start();
+```
+
+### 4. Wildcard Subdomain Handling
+
+Support multiple or dynamically created subdomains with one configuration:
+
+```typescript
+import { SmartProxy, createDomainConfig, tlsTerminateToHttp } from '@push.rocks/smartproxy';
+
+const multiTenantProxy = new SmartProxy({
+  fromPort: 443,
+  domainConfigs: [
+    // Handle all customer subdomains with one config
+    createDomainConfig('*.example.com', tlsTerminateToHttp({
+      target: { host: 'tenant-router', port: 8080 },
+      acme: { enabled: true, production: true },
+      // Pass original hostname to backend for tenant identification
+      advanced: {
+        headers: {
+          'X-Original-Host': '{sni}'
+        }
+      }
+    }))
+  ],
+  sniEnabled: true
+});
+
+await multiTenantProxy.start();
+```
+
+### 5. Comprehensive Proxy Server
+
+Create a complete proxy solution with multiple services on a single server:
+
+```typescript
+import { SmartProxy, createDomainConfig, httpOnly, tlsTerminateToHttp, tlsTerminateToHttps, httpsPassthrough } from '@push.rocks/smartproxy';
+
+const enterpriseProxy = new SmartProxy({
+  fromPort: 443,
+  domainConfigs: [
+    // Web application with automatic HTTPS
+    createDomainConfig('app.example.com', tlsTerminateToHttp({
+      target: { host: 'web-app', port: 8080 },
+      acme: { enabled: true, production: true },
+      http: { enabled: true, redirectToHttps: true }
+    })),
+
+    // Legacy system that needs HTTPS passthrough
+    createDomainConfig('legacy.example.com', httpsPassthrough({
+      target: { host: 'legacy-server', port: 443 }
+    })),
+
+    // Internal APIs with IP restrictions
+    createDomainConfig('api.internal.example.com', tlsTerminateToHttp({
+      target: { host: 'api-gateway', port: 3000 },
+      security: {
+        allowedIps: ['10.0.0.0/16', '192.168.0.0/16'],
+        maxConnections: 500
+      }
+    })),
+
+    // External services with customer certificate
+    createDomainConfig('external.example.com', tlsTerminateToHttps({
+      target: { host: 'external-service', port: 8443 },
+      https: {
+        customCert: {
+          key: fs.readFileSync('external-key.pem', 'utf8'),
+          cert: fs.readFileSync('external-cert.pem', 'utf8')
+        }
+      }
+    }))
+  ],
+  sniEnabled: true,
+  // Enable connection timeouts for security
+  inactivityTimeout: 30000,
+  // Using global certificate management
+  acme: {
+    enabled: true,
+    contactEmail: 'admin@example.com',
+    useProduction: true,
+    renewThresholdDays: 30
+  }
+});
+
+await enterpriseProxy.start();
+```
+
+## Unified Forwarding System Details
+
+SmartProxy's unified forwarding system supports four primary forwarding types:
+
+1. **HTTP-only (`http-only`)**: Forwards HTTP traffic to a backend server.
+2. **HTTPS Passthrough (`https-passthrough`)**: Passes through raw TLS traffic without termination (SNI forwarding).
+3. **HTTPS Termination to HTTP (`https-terminate-to-http`)**: Terminates TLS and forwards the decrypted traffic to an HTTP backend.
+4. **HTTPS Termination to HTTPS (`https-terminate-to-https`)**: Terminates TLS and creates a new TLS connection to an HTTPS backend.
+
+### Configuration Format
+
+Each domain is configured with a forwarding type and target:
+
+```typescript
+{
+  domains: ['example.com'],  // Single domain or array of domains (with wildcard support)
+  forwarding: {
+    type: 'http-only',       // One of the four forwarding types
+    target: {
+      host: 'localhost',     // Backend server (string or array for load balancing)
+      port: 3000             // Backend port
+    }
+    // Additional options as needed
+  }
+}
+```
+
+### Helper Functions
+
+Helper functions provide a cleaner syntax for creating configurations:
+
+```typescript
+// Instead of manually specifying the type and format
+const config = createDomainConfig('example.com', httpOnly({
+  target: { host: 'localhost', port: 3000 }
+}));
+
+// Available helper functions:
+// - httpOnly() - For HTTP-only traffic
+// - httpsPassthrough() - For SNI-based passthrough
+// - tlsTerminateToHttp() - For HTTPS termination to HTTP
+// - tlsTerminateToHttps() - For HTTPS termination to HTTPS
+```
+
+### Advanced Configuration Options
+
+For more complex scenarios, additional options can be specified:
+
+```typescript
+createDomainConfig('api.example.com', tlsTerminateToHttps({
+  // Target configuration with load balancing
+  target: {
+    host: ['10.0.0.10', '10.0.0.11'], // Round-robin load balancing
+    port: 8443
+  },
+

+    },
+    forwardSni: true                 // Forward original SNI to backend
+  },
+
+  // Let's Encrypt ACME integration
+  acme: {
+    enabled: true,                   // Enable automatic certificates

+    maintenance: true                // Auto-renew certificates
+  },
+
+  // Security settings
+  security: {
+    allowedIps: ['10.0.0.*'],        // IP allowlist (glob patterns)
+    blockedIps: ['1.2.3.4'],         // IP blocklist
+    maxConnections: 100              // Connection limits
+  },

+  // Advanced settings
+  advanced: {
+    timeout: 30000,                  // Connection timeout in ms

+    },
+    keepAlive: true                  // Keep connections alive

-# Plan: Fallback to NetworkProxy on Missing SNI
+# SmartProxy Interface & Type Naming Standardization Plan
 
-When a TLS ClientHello arrives without an SNI extension, we currently send a TLS alert and close the connection. Instead, if NetworkProxy is in use, we want to forward the connection to the network proxy first, and only issue the TLS error if proxying is not possible.
+## Project Goal
+Standardize interface and type naming throughout the SmartProxy codebase to improve maintainability, readability, and developer experience by:
+1. Ensuring all interfaces are prefixed with "I"
+2. Ensuring all type aliases are prefixed with "T"
+3. Maintaining backward compatibility through type aliases
+4. Updating documentation to reflect naming conventions
 
-## Goals
-- Allow TLS connections with no SNI to be forwarded to NetworkProxy when configured for any domain.
-- Only send a TLS unrecognized_name alert if proxy forwarding is unavailable or fails.
+## Phase 2: Core Module Standardization
 
-## Plan
-- [ ] In `ts/smartproxy/classes.pp.connectionhandler.ts`, locate the SNI-block branch in `handleStandardConnection` that checks `allowSessionTicket === false && isClientHello && !serverName`.
-- [ ] Replace the direct TLS alert/error logic with:
-  - If NetworkProxy is enabled (global `useNetworkProxy` setting or an active NetworkProxy instance), call `this.handleNetworkProxyConnection(socket, record)` (passing the buffered ClientHello) before issuing a TLS alert.
-  - Supply an error callback to `forwardToNetworkProxy`; if proxying fails or no NetworkProxy is available, fall back to the original TLS alert sequence.
-- [ ] Ensure existing metrics and cleanup (`record.incomingTerminationReason`, termination stats) are correctly tracked in the forwarding error path.
-- [ ] Add or update unit tests to simulate a TLS ClientHello without SNI on port 443 and verify:
-  - When NetworkProxy is enabled, the connection is forwarded to the proxy.
-  - If proxy forwarding fails or the domain is not configured, a TLS alert is sent and the socket is closed.
-- [ ] Run `pnpm test` to confirm no regressions and that the new behavior is correctly covered.

+## Implementation Strategy
+
+### Naming Pattern Rules
+
+1. **Interfaces**:
+   - All interfaces should be prefixed with "I"
+   - Example: `DomainConfig` → `IDomainConfig`
+
+2. **Type Aliases**:
+   - All type aliases should be prefixed with "T"
+   - Example: `ForwardingType` → `TForwardingType`
+
+3. **Enums**:
+   - Enums should be named in PascalCase without prefix
+   - Example: `CertificateSource`
+
+4. **Backward Compatibility**:
+   - No Backward compatibility. Remove old names.
+
+### Module Implementation Order
+
+1. Core module
+2. Certificate module
+3. Forwarding module
+4. Proxy implementations
+5. HTTP & TLS modules
+6. Main exports and entry points
+
+### Testing Strategy
+
+For each module:
+1. Rename interfaces and types
+2. Add backward compatibility aliases
+3. Update imports throughout the module
+4. Run tests to verify functionality
+5. Commit changes module by module
