# Phase 16 — v1.2-capstone-e2e (v1.2) VERIFY

**Verdict: Phase 16: VERIFIED** (capstone, up to IAM-blocked apply)
**Tag: v1.2.6**
**Date: 2026-07-21**

---

## Scope

Phase 16 is the v1.2 capstone: end-to-end verification of the full platform
flow (consumer content → contract → IR → adapter → terraform validate + plan)
+ the NFR improvements + the documentation + the v1.1 regression. The
`terraform apply` (the final step) is blocked by the IAM P0 (Phase 15);
this verify confirms everything *up to* the apply. Requirement: **REQ-35**.

## Verification layers

### 1. Structural
- `scripts/verify_phase16.sh` exists (+x, 11 assertions).
- `.ciagent/PLAN.md` updated to Phase 16.
- **PASS.**

### 2. Behavioral (`scripts/verify_phase16.sh`)
```
=== Phase 16 — v1.2 capstone e2e verification ===
Consumer microservice: OK
v1.2 contract -> IR -> adapter: OK (11 resources)
terraform validate + plan: OK (Plan: 13 to add, 0 to change, 0 to destroy.)
NFR improvements (Phase 12): OK (run_platform.sh + IAM expanded)
P1-1 redaction: OK (no live AWS key IDs)
README accuracy: OK
v1.1 S3 regression: OK
L1 catalog: OK (7 L1s)
l2-microservice: OK
.ciagent/ consistency: OK
outbox: OK (3 event(s))
Evidence events: OK

=== Phase 16: VERIFIED (capstone, up to IAM-blocked apply) ===
```

All 11 assertions pass. The full v1.2 platform is verified end-to-end up
to the `terraform apply`. The `MILESTONE_CAPSTONE_VERIFIED` evidence event
is written to the DynamoDB outbox.
- **PASS.**

### 3. Security
- No credentials introduced. The IAM P0 blocker is a security positive (least-privilege enforced; policy push requires a deliberate privileged action).
- **PASS.**

### 4. Quality
- The capstone verify exercises every v1.2 deliverable: consumer microservice (Phase 15), contract→IR→adapter pipeline (Phase 14), L1 catalog (Phase 13), NFR improvements (Phase 12), README (Phase 11), v1.1 S3 regression.
- The `terraform plan` (13 to add) confirms the adapter fixes from Phase 15 produce valid HCL for the full ECS microservice stack.
- **PASS.**

## P0 / P1
- **P0: 1 (carried from Phase 15 — operator action).** `terraform apply` blocked by IAM. Unblock: operator runs `create_iam_user.py` with root/admin creds, then `terraform apply` (13 to add) → live ECS service → HTTP 200. This completes REQ-33 + REQ-35.
- **P1: none new.**

## Requirements covered
- **REQ-35:** End-to-end verification — consumer commit → pipeline → ECS service → evidence event → timeline. **PARTIAL** (verified up to `terraform plan`; the `apply` + HTTP 200 check are the operator's post-unblock step). The `MILESTONE_CAPSTONE_VERIFIED` evidence event is in the outbox.

## Conclusion

Phase 16 is VERIFIED (capstone, up to the IAM-blocked apply). The v1.2
milestone is complete in code: all 6 phases shipped (v1.2.1–v1.2.6), the
platform flow is verified 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 (P0, documented). The milestone is ready for
the COMPLETE gate (review → ship v1.3.0 → audit).
