grabbit ca7e92a1a1 🎉 Epic 3 Complete: Production Readiness & Observability
Successfully implemented comprehensive monitoring and alerting infrastructure for the Meteor platform across all three stories of Epic 3:

**Story 3.5: 核心业务指标监控 (Core Business Metrics Monitoring)**
- Instrumented NestJS web backend with CloudWatch metrics integration using prom-client
- Instrumented Go compute service with structured CloudWatch metrics reporting
- Created comprehensive Terraform infrastructure from scratch with modular design
- Built 5-row CloudWatch dashboard with application, error rate, business, and infrastructure metrics
- Added proper error categorization and provider performance tracking

**Story 3.6: 关键故障告警 (Critical System Alerts)**
- Implemented SNS-based alerting infrastructure via Terraform
- Created critical alarms for NestJS 5xx error rate (>1% threshold)
- Created Go service processing failure rate alarm (>5% threshold)
- Created SQS queue depth alarm (>1000 messages threshold)
- Added actionable alarm descriptions with investigation guidance
- Configured email notifications with manual confirmation workflow

**Cross-cutting Infrastructure:**
- Complete AWS infrastructure as code with Terraform (S3, SQS, CloudWatch, SNS, IAM, optional RDS/Fargate)
- Structured logging implementation across all services (NestJS, Go, Rust)
- Metrics collection following "Golden Four Signals" observability approach
- Configurable thresholds and deployment-ready monitoring solution

The platform now has production-grade observability with comprehensive metrics collection, centralized monitoring dashboards, and automated critical system alerting.
