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

vpc — VPC with subnets and routing

Module kind: primitive | Version: 1.0.0

A VPC with one subnet per availability zone and a route table with a default route through an internet gateway. The networking foundation that other modules (ALB, ECS service) reference for subnet ids.

Resources

Resource Type Purpose
vpc aws_vpc The VPC itself
subnet aws_subnet One subnet per availability zone
route_table aws_route_table Route table with default route 0.0.0.0/0
internet_gateway aws_internet_gateway IGW for public internet access
route_table_association aws_route_table_association Binds subnet to route table

Inputs

Name Type Required Default Description
cidr string yes VPC CIDR block, e.g. 10.0.0.0/16
azs string yes Comma-separated availability zones, e.g. us-east-1a,us-east-1b
name string yes Name tag for the VPC and child resources
region string yes AWS region the VPC is created in

Outputs

Name Type Description
vpc_id string The VPC id
subnet_ids string Comma-separated subnet ids

Usage

{
  "id": "vpc",
  "type": "aws:ec2:vpc",
  "module": "vpc@1.0.0",
  "inputs": {
    "cidr": "10.0.0.0/16",
    "azs": "us-east-1a,us-east-1b",
    "name": "acdl-microservice",
    "region": "us-east-1"
  }
}

The azs input is split on comma; one subnet is created per zone. The route table gets a default route 0.0.0.0/0 → internet gateway. Other modules reference subnet_ids for their network placement.

Compliance extension points

  • VPC Flow Logs — add aws_flow_log + CloudWatch Logs group / S3 destination (SOX ITGC, SOC2 CC7.2, HIPAA §164.312(b), DORA ICT risk logging).
  • Private subnets + NAT gateway — add private subnets with a NAT gateway so ECS tasks don't need public IPs (SOC2 CC6.6, PCI-DSS 1.3, HIPAA network isolation).
  • VPC endpoints — add S3, ECR, KMS, DynamoDB, CloudWatch interface/gateway endpoints to keep traffic off the public internet (SOC2 CC6.7, GDPR Art.32(1)(a), DORA ICT third-party risk).
  • Security groups — add aws_security_group as a first-class sub-resource (currently missing; needed for all regulated deployments) (SOC2 CC6.6, PCI-DSS 1.2).
  • Network ACLs — add aws_network_acl for subnet-level segmentation (PCI-DSS 1.3).

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.
