Major improvements to telemetry system addressing code review findings: Architecture & Modularization: - Split 636-line TelemetryManager into 7 focused modules - Separated concerns: event tracking, batch processing, validation, rate limiting - Lazy initialization pattern to avoid early singleton creation - Clean separation of responsibilities Security & Privacy: - Added comprehensive input validation with Zod schemas - Sanitization of sensitive data (URLs, API keys, emails) - Expanded sensitive key detection patterns (25+ patterns) - Row Level Security on Supabase backend - Added data deletion contact info (romuald@n8n-mcp.com) Performance & Reliability: - Sliding window rate limiter (100 events/minute) - Circuit breaker pattern for network failures - Dead letter queue for failed events - Exponential backoff with jitter for retries - Performance monitoring with overhead tracking (<5%) - Memory-safe array limits in rate limiter Testing: - Comprehensive test coverage (87%+ for core modules) - Unit tests for all new modules - Integration tests for MCP telemetry - Fixed test isolation issues Data Management: - Clear user consent in welcome message - Batch processing with deduplication - Automatic workflow flushing BREAKING CHANGE: TelemetryManager constructor is now private, use getInstance() 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
