---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-ecr — ECR repository primitive
An L1 module for an ECR repository that hosts the ECS task image.
Single-purpose, substrate-agnostic (the IR type is
aws:ecr:repository, not a Terraform resource type).
Interface (the IR-typed contract)
See interface.json: inputs name + region (strings), outputs
repository_url (string) + repository_arn (arn), 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:ecr:repository |
resource "aws_ecr_repository" "<id>" { ... } |
resource.inputs.name |
name = <value> arg |
resource.inputs.region |
provider "aws" { region = <value> } |
resource.outputs.repository_url |
output "repository_url" { value = aws_ecr_repository.<id>.repository_url } |
resource.outputs.repository_arn |
output "repository_arn" { value = aws_ecr_repository.<id>.arn } |
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.
