+## Dynamic Route Updates
+
+When routes are updated dynamically using `updateRoutes()`, SmartProxy maintains certificate management continuity:
+
+```typescript
+// Update routes with new domains
+await proxy.updateRoutes([
+  {
+    name: 'new-domain',
+    match: { ports: 443, domains: 'newsite.example.com' },
+    action: {
+      type: 'forward',
+      target: { host: 'localhost', port: 8080 },
+      tls: {
+        mode: 'terminate',
+        certificate: 'auto'  // Will use global ACME config
+      }
+    }
+  }
+]);
+```
+
+### Important Notes on Route Updates
+
+1. **Certificate Manager Recreation**: When routes are updated, the certificate manager is recreated to reflect the new configuration
+2. **ACME Callbacks Preserved**: The ACME route update callback is automatically preserved during route updates
+3. **Existing Certificates**: Certificates already provisioned are retained in the certificate store
+4. **New Route Certificates**: New routes with `certificate: 'auto'` will trigger certificate provisioning
+
+### Route Update Best Practices
+
+1. **Batch Updates**: Update multiple routes in a single `updateRoutes()` call for efficiency
+2. **Monitor Certificate Status**: Check certificate status after route updates
+3. **Handle ACME Errors**: Implement error handling for certificate provisioning failures
+4. **Test Updates**: Test route updates in staging environment first

-# SmartProxy ACME Simplification Plan
+# SmartProxy Development Plan
 
-## Overview
+cat /home/philkunz/.claude/CLAUDE.md
-This plan addresses the certificate acquisition confusion in SmartProxy v19.0.0 and proposes simplifications to make ACME configuration more intuitive.
 
-## Current Issues
+## Critical Bug Fix: Missing Route Update Callback in updateRoutes Method
-1. ACME configuration placement is confusing (route-level vs top-level)
-2. SmartAcme initialization logic is complex and error-prone
-3. Documentation doesn't clearly explain the correct configuration format
-4. Error messages like "SmartAcme not initialized" are not helpful
 
-## Proposed Simplifications
+### Problem Statement
+SmartProxy v19.2.2 has a bug where the ACME certificate manager loses its route update callback when routes are dynamically updated. This causes the error "No route update callback set" and prevents automatic certificate acquisition.
 
-### 1. Support Both Configuration Styles
+### Root Cause
-- [x] Reread CLAUDE.md before starting implementation
+When `updateRoutes()` creates a new SmartCertManager instance, it fails to set the route update callback that's required for ACME challenges. This callback is properly set in `initializeCertificateManager()` but is missing from the route update flow.
-- [x] Accept ACME config at both top-level and route-level
-- [x] Use top-level ACME config as defaults for all routes
-- [x] Allow route-level ACME config to override top-level defaults
-- [x] Make email field required when any route uses `certificate: 'auto'`
 
-### 2. Improve SmartAcme Initialization
+### Implementation Plan
-- [x] Initialize SmartAcme when top-level ACME config exists with email
-- [x] Initialize SmartAcme when any route has `certificate: 'auto'`
-- [x] Provide clear error messages when initialization fails
-- [x] Add debug logging for ACME initialization steps
 
-### 3. Simplify Certificate Configuration
+#### Phase 1: Fix the Bug
-- [x] Create helper method to validate ACME configuration
+1. **Update the updateRoutes method** in `/mnt/data/lossless/push.rocks/smartproxy/ts/proxies/smart-proxy/smart-proxy.ts`
-- [x] Auto-detect when port 80 is needed for challenges
+   - [ ] Add the missing callback setup before initializing the new certificate manager
-- [x] Provide sensible defaults for ACME settings
+   - [ ] Ensure the callback is set after creating the new SmartCertManager instance
-- [x] Add configuration examples in documentation
 
-### 4. Update Documentation
+#### Phase 2: Create Tests
-- [x] Create clear examples for common ACME scenarios
+2. **Write comprehensive tests** for the route update functionality
-- [x] Document the configuration hierarchy (top-level vs route-level)
+   - [ ] Create test file: `test/test.route-update-callback.node.ts`
-- [x] Add troubleshooting guide for common certificate issues
+   - [ ] Test that callback is preserved when routes are updated
-- [x] Include migration guide from v18 to v19
+   - [ ] Test that ACME challenges work after route updates
+   - [ ] Test edge cases (multiple updates, no cert manager, etc.)
 
-### 5. Add Configuration Helpers
+#### Phase 3: Enhance Documentation
-- [x] Create `SmartProxyConfig.fromSimple()` helper for basic setups (part of validation)
+3. **Update documentation** to clarify the route update behavior
-- [x] Add validation for common misconfigurations
+   - [ ] Add section to certificate-management.md about dynamic route updates
-- [x] Provide warning messages for deprecated patterns
+   - [ ] Document the callback requirement for ACME challenges
-- [x] Include auto-correction suggestions
+   - [ ] Include example of proper route update implementation
 
-## Implementation Steps
+#### Phase 4: Prevent Future Regressions
+4. **Refactor for better maintainability**
+   - [ ] Consider extracting certificate manager setup to a shared method
+   - [ ] Add code comments explaining the callback requirement
+   - [ ] Consider making the callback setup more explicit in the API
 
-### Phase 1: Configuration Support ✅
+### Technical Details
-1. ✅ Update ISmartProxyOptions interface to clarify ACME placement
-2. ✅ Modify SmartProxy constructor to handle top-level ACME config
-3. ✅ Update SmartCertManager to accept global ACME defaults
-4. ✅ Add configuration validation and helpful error messages
-
-### Phase 2: Testing ✅
-1. ✅ Add tests for both configuration styles
-2. ✅ Test ACME initialization with various configurations
-3. ✅ Verify certificate acquisition works in all scenarios
-4. ✅ Test error handling and messaging
-
-### Phase 3: Documentation ✅
-1. ✅ Update main README with clear ACME examples
-2. ✅ Create dedicated certificate-management.md guide
-3. ✅ Add migration guide for v18 to v19 users
-4. ✅ Include troubleshooting section
-
-## Example Simplified Configuration
 
+#### Specific Code Changes
+1. In `updateRoutes()` method (around line 535), add:
    ```typescript
-// Simplified configuration with top-level ACME
+   // Set route update callback for ACME challenges
-const proxy = new SmartProxy({
+   this.certManager.setUpdateRoutesCallback(async (routes) => {
-  // Global ACME settings (applies to all routes with certificate: 'auto')
+     await this.updateRoutes(routes);
-  acme: {
-    email: 'ssl@example.com',
-    useProduction: false,
-    port: 80  // Automatically listened on when needed
-  },
-  
-  routes: [
-    {
-      name: 'secure-site',
-      match: { domains: 'example.com', ports: 443 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto'  // Uses global ACME settings
-        }
-      }
-    }
-  ]
-});
-
-// Or with route-specific ACME override
-const proxy = new SmartProxy({
-  routes: [
-    {
-      name: 'special-site',
-      match: { domains: 'special.com', ports: 443 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto',
-          acme: {  // Route-specific override
-            email: 'special@example.com',
-            useProduction: true
-          }
-        }
-      }
-    }
-  ]
    });
    ```
 
-## Success Criteria ✅
+2. Consider refactoring the certificate manager setup into a helper method to avoid duplication:
-1. ✅ Users can configure ACME at top-level for all routes
+   ```typescript
-2. ✅ Clear error messages guide users to correct configuration
+   private async setupCertificateManager(
-3. ✅ Certificate acquisition works with minimal configuration
+     routes: IRouteConfig[], 
-4. ✅ Documentation clearly explains all configuration options
+     certStore: string, 
-5. ✅ Migration from v18 to v19 is straightforward
+     acmeOptions?: any
+   ): Promise<SmartCertManager> {
+     const certManager = new SmartCertManager(routes, certStore, acmeOptions);
      
-## Timeline
+     // Always set up the route update callback
-- Phase 1: 2-3 days
+     certManager.setUpdateRoutesCallback(async (routes) => {
-- Phase 2: 1-2 days  
+       await this.updateRoutes(routes);
-- Phase 3: 1 day
+     });
      
-Total estimated time: 5-6 days
+     if (this.networkProxyBridge.getNetworkProxy()) {
+       certManager.setNetworkProxy(this.networkProxyBridge.getNetworkProxy());
+     }
      
-## Notes
+     return certManager;
-- Maintain backward compatibility with existing route-level ACME config
+   }
-- Consider adding a configuration wizard for interactive setup
+   ```
-- Explore integration with popular DNS providers for DNS-01 challenges
+
-- Add metrics/monitoring for certificate renewal status
+### Success Criteria
+- [x] ACME certificate acquisition works after route updates
+- [x] No "No route update callback set" errors occur
+- [x] All tests pass
+- [x] Documentation clearly explains the behavior
+- [x] Code is more maintainable and less prone to regression
+
+### Implementation Summary
+
+The bug has been successfully fixed through the following steps:
+
+1. **Bug Fix Applied**: Added the missing `setUpdateRoutesCallback` call in the `updateRoutes` method
+2. **Tests Created**: Comprehensive test suite validates the fix and prevents regression
+3. **Documentation Updated**: Added section on dynamic route updates to the certificate management guide
+4. **Code Refactored**: Extracted certificate manager creation into a helper method for better maintainability
+
+The fix ensures that when routes are dynamically updated, the certificate manager maintains its ability to update routes for ACME challenges, preventing the "No route update callback set" error.
+
+### Timeline
+- Phase 1: Immediate fix (30 minutes)
+- Phase 2: Test creation (1 hour)
+- Phase 3: Documentation (30 minutes)
+- Phase 4: Refactoring (1 hour)
+
+Total estimated time: 3 hours
+
+### Notes
+- This is a critical bug that affects production use of SmartProxy
+- The fix is straightforward but requires careful testing
+- Consider backporting to v19.2.x branch if maintaining multiple versions
