2.11.1

Clarify that the platform now organizes email functionality into distinct directories (mail/core, mail/delivery, mail/routing, mail/security, mail/services) and update the diagram and key features list accordingly. Adjust code examples to reflect explicit module imports and the use of SzPlatformService.

+# Smartlog Improvement Plan
+
+## Overview
+
+This document outlines a plan for enhancing the `@push.rocks/smartlog` module to incorporate the advanced features currently implemented in the custom `EnhancedLogger` wrapper. By moving these features directly into `smartlog`, we can eliminate the need for wrapper classes while providing a more comprehensive logging solution.
+
+## Current Limitations in Smartlog
+
+- Limited context management (no hierarchical contexts)
+- No correlation ID tracking for distributed tracing
+- No built-in filtering or log level management
+- No log sampling capabilities
+- No middleware for HTTP request/response logging
+- No timing utilities for performance tracking
+- No child logger functionality with context inheritance
+
+## Proposed Enhancements
+
+### 1. Context Management
+
+- Add hierarchical context support
+- Implement methods for manipulating context:
+  - `setContext(context, overwrite = false)`
+  - `addToContext(key, value)`
+  - `removeFromContext(key)`
+
+### 2. Correlation ID Tracking
+
+- Add correlation ID support for distributed tracing
+- Implement methods for correlation management:
+  - `setCorrelationId(id = null)`
+  - `getCorrelationId()`
+  - `clearCorrelationId()`
+
+### 3. Log Filtering
+
+- Implement configurable log filtering based on:
+  - Minimum log level
+  - Pattern-based exclusion rules
+  - Custom filtering functions
+
+### 4. Log Sampling
+
+- Add probabilistic log sampling for high-volume environments
+- Support for enforcing critical logs (e.g., errors) regardless of sampling
+
+### 5. Child Loggers
+
+- Support creating child loggers with inherited context
+- Allow context overrides in child loggers
+
+### 6. Timing Utilities
+
+- Add methods for timing operations:
+  - `logTimed(level, message, fn, context)`
+  - Support for both async and sync operations
+
+### 7. HTTP Request Logging
+
+- Add middleware for Express/Fastify/other HTTP frameworks
+- Auto-capture request/response data
+- Auto-propagate correlation IDs
+
+### 8. Log Standardization
+
+- Ensure consistent output format
+- Add standard fields like timestamp, correlation ID
+- Support for custom formatters
+
+## Implementation Plan
+
+1. **Core Enhancements**
+   - Implement context management
+   - Add correlation ID tracking
+   - Develop filtering and sampling capabilities
+
+2. **Extended Features**
+   - Build child logger functionality
+   - Create timing utility methods
+   - Implement HTTP middleware
+
+3. **Compatibility**
+   - Ensure backward compatibility
+   - Provide migration guide
+   - Add TypeScript declarations
+
+4. **Documentation**
+   - Update README with new features
+   - Add examples for each feature
+   - Document best practices
+
+## Migration Path
+
+After implementing these enhancements to `smartlog`, the migration would involve:
+
+1. Update to latest `smartlog` version
+2. Replace `EnhancedLogger` instances with `smartlog.Smartlog`
+3. Update configuration to use new capabilities
+4. Replace middleware with `smartlog`'s built-in solutions
+
+## Benefits
+
+- Simplified dependency tree
+- Better maintainability with single logging solution
+- Improved performance with native implementation
+- Enhanced type safety through TypeScript
+- Standardized logging across projects
