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.

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.
