Jon Chery 553caf8f1d docs(P21): rewrite README + normalize modules terminology (REQ-52,55,56,57,58,59,60)
---ci---
project: acdl
phase: 21
milestone: v1.6
status: execute
---/ci---

README.md rewrite:
- Remove all .ciagent/ references (links + repository-layout row).
- Remove .gitea/workflows/ row from repository layout.
- Restate repository roles: consumer repo = app code + 1+ contracts +
  CI definitions (thin .github/workflows/*.yml uses:-ing the central
  workflow); platform repo owns modules/adapters/core/schemas/pipelines/
  scripts/workflows.
- Replace Status section with Features list (consumer + platform-engineer
  referenceable) + Roadmap (planned only, no version changelog, no
  internal CIAgent status). Includes the composition-redesign roadmap
  entry (dynamic module creation from a contract).
- Fix the mermaid flowchart: all node text visible (short multi-line
  labels via <br/>), add a security-checks stage before policy checks,
  do not name specific tools (security checks/policy checks/infrastructure
  plan via adapter), add infrastructure-apply stage (dev only, after
  evidence event).
- Remove the environments table (dev/qa/prod/dr) completely; point to
  docs/environments/ for platform-managed environments.
- Credentials section: remove go-gitea/gitea#36988 blocked mention +
  waivers D-039/D-047 language. State OIDC+ABAC default; alternative is a
  static AWS key (GitHub Secrets for platform-runner runs, .env.secrets
  locally) with daily rotation (platform-managed) or out-of-band rotation
  (consumer-managed for local .env.secrets).
- forge -> platform runners / platform-managed throughout.
- Links point to docs/ Pages paths, not .ciagent/.

modules/ terminology:
- modules/README.md: L1 primitives -> primitives, L2 compositions ->
  modules, composition -> pattern (prose); add roadmap note for the
  composition redesign.
- README-TEMPLATE.md: L1 primitive -> primitive.
- All 7 L1 READMEs: L1 primitive -> primitive.
- L2 static-asset + microservice READMEs: L2 composition -> module
  pattern, composition -> pattern, L1 -> primitive; bump stale @v1 ->
  @v1.4 in usage examples; fix CONSUMER_GUIDE.md -> consumer-guide.md
  link.

Verification: grep sweeps for .ciagent/.gitea/forge/go-gitea/waiver/
D-039/D-047/acdl_platform in docs/ README.md modules/ contracts/ all
return 0 hits. Tests: 166 pass. run_ci.sh green.

microservice — ECS Fargate microservice

Module kind: module pattern | Version: 1.0.0

A pattern that references multiple primitives to deploy an ECS Fargate microservice end-to-end (VPC, cluster, ECR, IAM role, ALB, ECS service).

Resources

The pattern references these primitives:

Primitive Purpose README
vpc VPC, subnets, routing README
ecs-cluster ECS Fargate cluster README
ecr ECR image repository README
iam-role IAM task execution role README
alb Application Load Balancer README
ecs-service ECS task definition + service README

Inputs

Name Type Required Description
image string yes ECR image URL for the task container
port number yes Container port the service listens on
region string yes AWS region
cidr string no VPC CIDR block (default 10.0.0.0/16)
azs string no Comma-separated availability zones

Outputs

Name Type Description
lb_arn arn The load balancer ARN
service_arn arn The ECS service ARN

Usage

Define a contract referencing this module:

uses: acdl/pipelines/deploy.yaml@v1.4
module: microservice
environment: dev
inputs:
  image: 581513795199.dkr.ecr.us-east-1.amazonaws.com/acdl-microservice:latest
  port: 8080
  region: us-east-1

Compliance extension points

The pattern can wire compliance resources across primitives 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 primitive's README for per-module compliance extension points.

Versioning

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.
