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

iam-role — IAM role

Module kind: primitive | Version: 1.0.0

A single IAM role with an assume-role policy and optional managed policy attachments. Used as the ECS task execution role.

Resources

Resource Type Purpose
role aws_iam_role The IAM role with assume-role policy

Inputs

Name Type Required Default Description
role_name string yes The IAM role name
assume_role_policy string yes Assume-role policy document (JSON string)
managed_policies string no Comma-separated list of managed policy ARNs to attach
region string yes AWS region the role is created in

Outputs

Name Type Description
role_arn arn The IAM role ARN
role_id string The IAM role id

Usage

{
  "id": "roles",
  "type": "aws:iam:role",
  "module": "iam-role@1.0.0",
  "inputs": {
    "role_name": "acdl-microservice-exec",
    "assume_role_policy": "{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":{\"Service\":\"ecs-tasks.amazonaws.com\"},\"Action\":\"sts:AssumeRole\"}]}",
    "managed_policies": "arn:aws:iam::aws:policy/service-role/AmazonECSTaskExecutionRolePolicy",
    "region": "us-east-1"
  }
}

The assume_role_policy is a JSON string — the adapter jsonencodes it into the Terraform assume_role_policy argument. The managed_policies input is a comma-separated list of ARNs, emitted as managed_policy_arns = [...].

Compliance extension points

  • Permissions boundary — add permissions_boundary to enforce least-privilege guardrails (SOC2 CC6.1, SOX ITGC, DORA ICT access control).
  • Inline policy — add aws_iam_role_policy for fine-grained least-privilege instead of broad managed policies (SOC2 CC6.1, HIPAA §164.308(a)(4)).
  • MFA conditions — add condition blocks requiring MFA for assume-role (SOC2 CC6.1, HIPAA §164.312(d)).
  • Source IP / region conditions — add aws:SourceIp / aws:RequestedRegion conditions for data residency enforcement (GDPR Art.44-49, DORA ICT third-party risk).
  • Access Analyzer — add aws_accessanalyzer_analyzer to verify least-privilege (SOC2 CC6.1, GDPR Art.32).
  • Role separation — add a separate task role vs. execution role (SOC2 CC6.3 segregation of duties).

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.
