---ci--- project: acdl phase: 13 milestone: v1.2 status: verify verdict: VERIFIED requirements: covered: [REQ-31] ---/ci--- Phase 13 plan-as-execute + verify. scripts/verify_phase13.sh green. 6 ECS L1s authored + registered (l1-vpc, l1-ecs-cluster, l1-ecs-service, l1-iam-role, l1-alb, l1-ecr). Adapter generalized to table-driven TYPE_MAP (12 IR types) + INPUT_MAP + OUTPUT_MAP. S3 regression: the v1.1 spike l1-s3 produces byte-identical main.tf. Ready to ship v1.2.3.
l1-ecs-cluster — ECS Fargate cluster primitive
An L1 module for an ECS Fargate cluster. Single-purpose,
substrate-agnostic (the IR type is aws:ecs:cluster, not a Terraform
resource type).
Interface (the IR-typed contract)
See interface.json: inputs name + region (strings), outputs
cluster_arn (arn) + cluster_id (string), no NFRs.
IR → Terraform mapping (performed by the adapter)
The Terraform adapter (adapters/terraform/adapter.py) translates this
L1's IR shape to Terraform:
| IR | Terraform |
|---|---|
resource.type = aws:ecs:cluster |
resource "aws_ecs_cluster" "<id>" { ... } |
resource.inputs.name |
name = <value> arg |
resource.inputs.region |
provider "aws" { region = <value> } |
resource.outputs.cluster_arn |
output "cluster_arn" { value = aws_ecs_cluster.<id>.arn } |
resource.outputs.cluster_id |
output "cluster_id" { value = aws_ecs_cluster.<id>.id } |
The adapter is a thin layer (ARCHITECTURE.md §12.2); it does not own L1 content — it only translates.
Versioning (W3.D)
1.0.0 — interface MAJOR, behavior MINOR, lifecycle PATCH. MAJOR bumps
require a new registry entry (immutable publication); old entries enter
a 12-month deprecation window.
