review(v1.5): READY TO SHIP — multi-persona code review
---ci---
project: acdl
phase: 20
milestone: v1.5
status: review
verdict: READY TO SHIP
p0: 1 (fixed — contract path resolution in deploy workflow)
p1: 6 (flagged post-hoc)
---/ci---

Multi-persona review of v1.5 phase 20 (docs + reusable deploy workflow).

P0 (blocking) — AUTO-FIXED:
- C1: scripts/run_platform.sh contract path resolution broken in deploy
  workflow. The reusable workflow invokes run_platform.sh from the consumer
  workspace root with a relative contract path (.acdl/contract.yaml), but
  run_platform.sh does `cd "$ROOT"` (platform repo) early, so the relative
  path resolved against the platform repo and the pipeline could never run.
  Fix (commit 75c2274): capture CALLER_CWD before cd "$ROOT"; resolve
  caller-supplied relative paths against CALLER_CWD; default no-arg contract
  stays relative to ROOT (preserves platform-local CI). Reproduced pre-fix;
  verified post-fix.

P1 (important) — FLAGGED FOR POST-HOC REVIEW (do not block ship):
- C2: ref: v1.4 in the deploy workflow platform checkout — no v1.4 tag exists
  (only v1.4.0 / v1.4.1). Operator must create a floating v1.4 tag or change
  the ref to v1.4.1.
- C3: modules/l2/{static-asset,microservice}/README.md still use @v1 in their
  Usage examples; missed by the v1.4 bump.
- S1: static-key override is not wired. ACDL_AWS_* env vars on the OIDC step
  are not read by aws-actions/configure-aws-credentials@v4 (it reads AWS_*
  or its own access-key/secret-key inputs). The README/CONSUMER_GUIDE claim
  a working override that doesn't function as written. Needs a conditional
  step or renamed env vars + input wiring.
- S2: README overstates ABAC repo:org/repo:ref:... scoping. The workflow
  constructs a numeric role name (github.repository_id); the actual claim
  enforcement lives in the IAM trust policy, not in this workflow.
- T1: no deploy-workflow triggers conformance test (CI workflow has one;
  deploy doesn't). Minor — reusable workflows use workflow_call, not push
  triggers, but the contract's triggers field is then unenforced.
- A1: terraform/spike/terraform.tf uploaded as artifact leaks the AWS account
  ID via the state-backend bucket name. Recommend excluding terraform.tf or
  gating artifact upload to non-public repos.

P2 (nits) — listed for awareness: floating-tag terminology imprecision (M1),
  header comment "Gitea Actions" in the GitHub copy (M2, intentional byte-
  identical), pip install split (P1-perf), comment drift in pipelines/deploy.yaml
  header (C4), module README internal inconsistency (C5).

Verdict: READY TO SHIP. The one P0 is fixed. The 6 P1s are post-hoc items —
the deploy workflow is a scaffold whose first real consumer run requires
operator setup (tag, IAM role, secrets) that gates go-live. The P1s should
be addressed before any consumer invokes uses: acdl/.gitea/workflows/
deploy.yml@v1.4 in earnest.

Tests: 154 pass (19 new). run_ci.sh green.

# ecs-cluster — ECS Fargate cluster
> **Module kind:** L1 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
```json
{
"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.
