Jon Chery 90be5839ab feat(P26): 3 platform pipelines + release job with semver/tag updates
Phase 26 — platform-pipelines-and-release-automation:

- platform-test.yml: PR pipeline (lint + unit-test + integration-test +
  schema-validation) replacing ci.yml for PRs; integration-test runs
  run_platform.sh --check-only for every contracts/*.yaml
- primitives-plan.yml: PR pipeline with matrix over all 9 L1 primitives
  (s3, vpc, ecs-cluster, ecs-service, iam-role, alb, ecr, cloudfront, waf)
- patterns-plan.yml: PR pipeline with matrix over all 2 L2 modules
  (static-assets, microservice)
- release.yml: push-to-main pipeline computing next semver tag (PATCH for
  regular phases, MINOR for milestone completions), updating floating
  MAJOR.MINOR + MAJOR tags, and creating GitHub releases
- run_primitive_plan.sh: plan-only/check-only runner for a single L1
  primitive (adapter compile + structure validation offline)
- run_pattern_plan.sh: plan-only/check-only runner for a single L2 pattern
  (environment check + contract validate + resolve + adapter + structure
  validation offline)
- contracts/microservice.yaml: sample consumer contract for the
  microservice L2 module (schema-compliant scalar inputs)
- instance.json for 8 L1 primitives (vpc, ecs-cluster, ecs-service,
  iam-role, alb, ecr, cloudfront, waf) so the primitives-plan matrix can
  run the adapter offline; s3 already had one
- tests/test_release_logic.py: unit test for semver computation
  (PATCH bump, MINOR bump on milestone, floating tag format)
- tests/test_pipeline_contract.py: 19 new tests validating the 4 platform
  workflows exist and conform (stages, matrices, triggers, permissions)

DEVIATION: The microservice pattern (run_pattern_plan.sh --check-only
microservice + run_platform.sh --check-only contracts/microservice.yaml)
fails at the adapter stage due to a pre-existing resolver ref-id mismatch
for multi-resource L1s (resolver emits ref:vpc.subnet_ids but the expanded
resource id is vpc-subnet). This predates Phase 26 and is out of scope for
pipeline automation; the static-assets pattern passes end-to-end. The
microservice contract is schema-valid and resolves correctly (11
resources); only the adapter compilation of multi-resource L1 refs fails.

VERIFICATION:
- bash scripts/run_ci.sh: PASS (lint + test + check-only)
- python3 -m pytest tests/ -v: 266 passed
- bash scripts/run_primitive_plan.sh --check-only s3: PASS
- bash scripts/run_pattern_plan.sh --check-only static-assets: PASS
- All 9 primitives pass run_primitive_plan.sh --check-only
- All instance.json validate against stack.schema.json

ecs-cluster — ECS Fargate cluster

Module kind: primitive | Version: 1.0.0

An ECS Fargate cluster. The simplest ECS module — one resource, two inputs, two outputs. The cluster is the container orchestration boundary that ecs-service references for task placement.

Resources

Resource Type Purpose
cluster aws_ecs_cluster The ECS Fargate cluster

Inputs

Name Type Required Default Description
name string yes The ECS cluster name
region string yes AWS region the cluster is created in

Outputs

Name Type Description
cluster_arn arn The ECS cluster ARN
cluster_id string The ECS cluster id (name)

Usage

{
  "id": "cluster",
  "type": "aws:ecs:cluster",
  "module": "ecs-cluster@1.0.0",
  "inputs": {
    "name": "acdl-microservice",
    "region": "us-east-1"
  }
}

The cluster_arn output is referenced by ecs-service as its cluster_arn input.

Compliance extension points

  • Container Insights — add configuration { container_insights = "enabled" } for observability (SOC2 CC7.3, DORA ICT risk monitoring).
  • CloudWatch Logs — add a log group with retention policy for cluster-level audit logs (SOX, SOC2 CC7.2, HIPAA §164.312(b)).
  • Encryption — add settings { name = "containerInsights", value = "enabled" } and KMS-based encryption for container data (HIPAA §164.312(a)(2)(iv), GDPR Art.32).

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.
