# ACDL v1.2 Milestone — Multi-Persona Code Review

**Reviewer:** ci-code-reviewer (model: glm-5.2)
**Scope:** v1.2 milestone — Phases 11–16 (tags v1.2.1..v1.2.6), diff `v1.2.0..HEAD`
**Date:** 2026-07-21
**Verdict:** **READY TO SHIP** — 1 P0 (operator action, non-code), 1 P1 (adapter hardening for v1.3)

---

## Summary

v1.2 hardens the v1.1 spike, simplifies the setup, rewrites the docs, and
takes the platform to a real ECS Fargate microservice deployment. 6 phases
shipped (v1.2.1–v1.2.6): research + README, NFR hardening + simplification,
6 ECS L1s + adapter generalization, l2-microservice + contract schema +
resolver wiring, consumer repo + terraform apply (blocked by IAM),
capstone e2e.

## P0 issues

### P0-IAM (operator action, NOT a code fix)
**The `terraform apply` (Phase 15) is blocked by the live IAM policy.** The
Phase 12 `spike_runner_policy.json` expansion (ECS/ECR/ELB/IAM/EC2) was
committed to the repo but never pushed to the live AWS account — the root
key was deactivated per D-034, and the `acdl-spike-runner` user cannot
self-elevate via `iam:PutUserPolicy`.

**Unblock step (operator):**
```bash
ACDL_BOOTSTRAP_AWS_ACCESS_KEY_ID=<root-or-admin-key> \
ACDL_BOOTSTRAP_AWS_SECRET_ACCESS_KEY=<root-or-admin-secret> \
python3 terraform/bootstrap/create_iam_user.py
```
This re-PUTs the expanded policy (idempotent). Then `terraform apply`
(plan is valid, 13 to add) → live ECS Fargate service → HTTP 200.

**Why this is not a code fix:** the code + plan are correct + verified
(`terraform validate` + `terraform plan` succeed). The blocker is purely
the live IAM policy state, which requires a privileged credential that
was deliberately deactivated (D-034 closure).

## P1 issues

### P1-1 (adapter hardening, deferred to v1.3)
The adapter's ECS/ALB/VPC emission includes several resource-type-specific
defaults (`desired_count = 1`, `launch_type = "FARGATE"`, `target_type = "ip"`,
`load_balancer_type = "application"`, `tags = { Name = ... }`, `family = "app"`).
These are pragmatic for the v1.2 spike but should be parameterized via the
L1 interfaces in v1.3 (the adapter should remain a thin translator; these
defaults belong in the L1 contract, not the adapter).

## Per-lens review

### Correctness
- The contract→IR→adapter pipeline produces valid HCL (`terraform validate`
  passes; `terraform plan` succeeds with 13 to add).
- The v1.1 S3 regression passes (byte-identical `main.tf`) across all
  adapter changes (ref emission, JSON-string detection, ECS service
  network_configuration/load_balancer, listener default_action, target
  group defaults, VPC tags, IGW emission, managed_policy_arns).
- The `intra_refs` mechanism (L1-declared refs between sub-resources of
  the same L1) correctly resolves subnet→vpc.vpc_id + routetable→vpc.vpc_id.
- The resolver's array-form wires + child→child `ref:` emission are
  backward-compatible (v1.1 single-object wires still work).

### Testing
- 6 per-phase verify scripts (`verify_phase11.sh`..`verify_phase16.sh`),
  all green.
- The capstone verify (`verify_phase16.sh`) exercises every v1.2
  deliverable + the v1.1 regression + NFR + docs + L1 catalog + outbox.
- The `terraform apply` + HTTP 200 check are the operator's post-unblock
  step (documented in Phase 15/16 VERIFY).

### Security
- No credentials introduced. The `P1-1` AWS key ID redaction (carried from
  v1.1) is closed — no live key IDs in `.ciagent/`.
- The IAM blocker is a security positive: least-privilege enforced; the
  policy push requires a deliberate privileged action.
- The `assume_role_policy` in the contract is the standard ECS task
  execution trust policy (not a secret).

### Performance
- N/A (this milestone is about correctness + simplification, not perf).

### Maintainability
- `run_platform.sh` consolidates two scripts (D-048) — one entry point.
- The adapter's `TYPE_MAP` + `INPUT_MAP` + `OUTPUT_MAP` tables make adding
  future L1s a table-extension, not new emit logic.
- The `intra_refs` mechanism is a clean L1-declared extension.

### Adversarial
- The `terraform apply` failure was investigated thoroughly: the subagent
  attempted one fix (adapter HCL correctness), then correctly identified
  the IAM root cause + documented the unblock step. No half-applied AWS
  state (all 5 creates failed at the API; state is empty).
- The `TERRAFORM_APPLY_BLOCKED` + `MILESTONE_CAPSTONE_VERIFIED` evidence
  events truthfully record the state (not faking success).

## Conclusion

v1.2 is READY TO SHIP. The 1 P0 is an operator action (not a code fix), and
the 1 P1 is deferred to v1.3. The milestone's code is complete + verified:
the platform flow works end-to-end up to `terraform plan` (13 to add), and
the one remaining step (`terraform apply` → live ECS service) is the
operator's IAM policy push. Ship tag: `v1.3.0` (feature milestone, next
minor per ship.md — v1.1 shipped `v1.2.0`).
