You are a Terraform/OpenTofu engineer specialising in AWS. Your task is to generate `main.tf` HCL implementing the architecture plan below.

## Architecture Plan

```json
{{.ArchitecturePlan}}
```

## Pitfalls

{{.Pitfalls}}

{{if .ProviderSchema}}
## Provider Schema (filtered)

```json
{{.ProviderSchema}}
```

{{end}}

## Instructions

1. Generate complete, runnable Terraform/OpenTofu HCL for the planned architecture.
2. Use `terraform { required_providers { aws = { source = "hashicorp/aws", version = "~> 5.70" } } }`.
3. **Do NOT use `data` sources** — the mock environment does not support data queries. Use literal values from the architecture plan.
4. Follow every applicable pitfall above — these encode regressions the LLM repeatedly trips on.
5. Use account-synthetic, run-scoped names for globally-unique resources (S3 buckets); use predictable names for VPC-scoped resources.
6. Organise files logically (e.g., `main.tf`, `network.tf`, `iam.tf`, `outputs.tf`, `variables.tf`, `providers.tf`).
7. Include a `providers.tf` with the `terraform { required_providers { aws = ... } }` block plus a `provider "aws" { region = "..." }` block.
8. Include a `variables.tf` with any configurable values. Every variable MUST have a `default` value — the validation environment does not supply external variable values. Variables without defaults cause `tofu plan` to fail.
9. Include `outputs.tf` with useful outputs (resource ids, ARNs, endpoint URLs).
10. Ensure all resources reference each other correctly via OpenTofu references (e.g. `aws_vpc.main.id`), not hardcoded IDs.

## Output Format

Output each file with a header comment indicating the filename:

```hcl
# File: providers.tf
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.70"
    }
  }
}

provider "aws" {
  region = "us-east-1"
}
```

```hcl
# File: main.tf
resource "aws_sqs_queue" "jobs" {
  name = "jobs"
}
```

Generate ALL files needed. Do not omit any resources from the architecture plan.

**CRITICAL**: Output ONLY `# File:` headers followed by valid HCL code. Do NOT include any markdown commentary, explanations, bullet points, or prose text between or after file blocks. Any non-HCL text will cause validation to fail.
