The L2 thin-composition layer (composition.json + contract_resolver.py + contract schema + sample contracts) has been removed completely. The implementation was unsatisfactory and is deferred for a later redesign. - Delete: composition.json x2, contract_resolver.py, contracts/ x2, contract.schema.json - Patch: run_platform.sh now loads a pre-existing IR instance instead of resolving a contract (the downstream adapter/checkov/confidence/outbox pipeline is unchanged) - Prune: L2 entries removed from registry.json (L1 entries unchanged) - Rewrite: all 7 L1 module READMEs in plain language (no jargon), each with Resources/Inputs/Outputs/Usage/Compliance-extension-points/Versioning sections derived from interface.json - Add: 2 L2 placeholder READMEs noting the composition is under redesign - Add: modules-ir/README.md catalog index + README-TEMPLATE.md ---ci--- project: acdl phase: 17 milestone: v1.3 status: execute ---/ci---
l2-microservice — ECS Fargate microservice (composition being redesigned)
Module kind: L2 composition | Version: TBD | Status: Under redesign
A composition that references multiple L1 primitives to deploy an ECS Fargate microservice end-to-end (VPC, cluster, ECR, IAM role, ALB, ECS service).
The composition layer is being redesigned. The previous
thin-composition implementation (a composition.json with children +
wires) has been removed. A new composition mechanism will be designed
in a later phase.
Resources
TBD — the composition will reference these L1 primitives:
| L1 module | Purpose | README |
|---|---|---|
l1-vpc |
VPC, subnets, routing | README |
l1-ecs-cluster |
ECS Fargate cluster | README |
l1-ecr |
ECR image repository | README |
l1-iam-role |
IAM task execution role | README |
l1-alb |
Application Load Balancer | README |
l1-ecs-service |
ECS task definition + service | README |
Inputs
TBD — will be defined when the composition mechanism is redesigned.
Outputs
TBD — will be defined when the composition mechanism is redesigned.
Usage
TBD — the composition mechanism is being redesigned. Until then, use the L1 primitives directly. See each L1 module's README for usage examples.
Compliance extension points
The composition will need to wire compliance resources across L1s when the compliance milestone (GDPR, SOX, SOC2, HIPAA, DORA) lands:
- KMS key — shared encryption key referenced by S3, ECR, CloudWatch Logs, and Secrets Manager.
- CloudTrail — management-plane audit trail for the entire stack.
- VPC Flow Logs — network audit trail.
- Security groups — proper network segmentation between ALB, service, and data tiers.
- Private subnets — ECS tasks in private subnets with NAT egress.
See each L1 module's README for per-module compliance extension points.
Versioning
Versioning will be defined when the composition mechanism is redesigned.
