📄 Description

Summary

Implements Terraform infrastructure-as-code for AWS, providing a complete foundation for deploying Shannon platform resources across dev, staging, and production environments.

Changes

Phase 1: Project Setup

Terraform version constraint (1.6.0) via .terraform-version
TFLint configuration with AWS ruleset for linting
Infrastructure README with quick start guide
Updated .gitignore with Terraform patterns

Phase 2: Bootstrap Module

S3 bucket for remote state storage (AES-256 encryption, versioning enabled)
DynamoDB table for state locking
Public access blocking on state bucket

Phase 3: Networking Module + Dev Environment

Networking module with:
- VPC with configurable CIDR
- Public and private subnets across multiple AZs
- Internet Gateway and NAT Gateway(s)
- Route tables with proper associations
- Security groups for ALB, application servers, and databases
Dev environment configured with cost-optimized settings (t3.micro, single NAT)

Phase 4: Multi-Environment Support

Staging environment: t3.small instances, single NAT, 10.1.0.0/16 CIDR
Production environment: t3.medium instances, multi-AZ NAT (HA), 3 AZs, 10.2.0.0/16 CIDR

Environment Comparison

Setting	Dev	Staging	Prod
VPC CIDR	10.0.0.0/16	10.1.0.0/16	10.2.0.0/16
Availability Zones	2	2	3
Instance Type	t3.micro	t3.small	t3.medium
NAT Gateway	Single	Single	Multi-AZ
ASG Min/Max	1/2	2/4	3/10
RDS Multi-AZ	No	No	Yes

Specification Updates

Added 5 clarifications to spec.md (IAM permissions, promotion workflow, naming convention, timeouts, validation)
Updated author-review checklist (15/15 items resolved)
Marked 33/90 tasks complete in tasks.md

Testing

Terraform CLI validation required locally:

cd infrastructure/bootstrap && terraform init && terraform validate
cd infrastructure/environments/dev && terraform init && terraform validate
cd infrastructure/environments/staging && terraform init && terraform validate
cd infrastructure/environments/prod && terraform init && terraform validate
