# Phase 10 — v1-spike-l2-and-contract-e2e (v1.1) VERIFY

**Verdict: Phase 10: VERIFIED**
**Tag: v1.1.5** — milestone capstone shipped.

The phase goal is genuinely achieved. The end-to-end spike pipeline runs
green against real AWS, and REQ-28 (the binding spike claim — the IR
commitments hold, the adapter is the only substrate-specific code) is
proven by `scripts/verify_phase10.sh` Check (h).

---

## Layer 1 — Structural: PASS

### Deliverable files (9 + regenerated TF)

All 9 Phase 10 deliverable files exist; the regenerated TF is present:

| File | Exists | Notes |
|------|--------|-------|
| `modules-ir/l2/l2-static-asset/composition.json` | ✅ | kind=l2, depth=1, one child `l1-s3@1.0.0`, wires passthrough (`bucket_name`→s3.bucket_name, `region`→s3.region) |
| `modules-ir/l2/l2-static-asset/README.md` | ✅ | D-P10-1 doc; references l1-s3 only; internally consistent |
| `modules-ir/registry.json` | ✅ | both `l1-s3@1.0.0` + `l2-static-asset@1.0.0` entries present |
| `contracts/spike.yaml` | ✅ | valid YAML; stack=l2-static-asset, environment=dev, inputs bucket_name=acdl-spike-bucket, region=us-east-1 |
| `acdl_platform/contract_resolver.py` | ✅ | `resolve()` + `__main__` CLI; loads YAML → validates contract schema → looks up L2 → loads composition → maps wires → emits IR → validates IR schema |
| `adapters/terraform/adapter.py` | ✅ | D-P10-1: backend key derived from stack name (`spike/<stack_name>/terraform.tfstate`); handles both l1 + l2 IR (resources array is the same shape) |
| `acdl_platform/outbox_writer.py` | ✅ | `write_event()` + `__main__` CLI; SHA-256 canonical JSON hash; GENESIS chain; TTL expire_at; single `put_item` (append-only) |
| `scripts/run_spike_e2e.sh` | ✅ | 8-step orchestrator; bash -n passes |
| `scripts/verify_phase10.sh` | ✅ | 8-check gate; bash -n passes |
| `terraform/spike/main.tf` | ✅ | `resource "aws_s3_bucket" "s3"` + versioning + bucket_arn/bucket_name outputs (regenerated by adapter) |
| `terraform/spike/terraform.tf` | ✅ | `key = "spike/l2-static-asset/terraform.tfstate"` — derived from stack name per D-P10-1 |
| `terraform/spike/providers.tf` | ✅ | aws provider, region=us-east-1 |

### Tags + .gitignore
- Tags `v1.1.0`..`v1.1.5` all present.
- `.gitignore` line 14: `terraform/spike/.terraform.lock.hcl` (P1-2 fix from P10 prep 798f430).

## Layer 2 — Behavioral: PASS

### Gate re-run (real AWS)

```
$ bash scripts/verify_phase10.sh
ok: composition.json: l2-static-asset references l1-s3 only (depth 1)
ok: contracts/spike.yaml validates against the contract schema
ok: contract_resolver.py resolves spike.yaml to an IR-schema-valid instance
ok: adapter.py compiles L2 IR to terraform with aws_s3_bucket
ok: run_spike_e2e.sh completes the full pipeline end-to-end
ok: confidence band is pass for dev
ok: evidence event is written to the DynamoDB outbox
ok: REQ-28: adapter is the only substrate-specific code; modules-ir/ + acdl_platform/ are substrate-agnostic (docs/comments excluded)
VERIFIED — Phase 10: L2 + contract-e2e; IR commitments hold (REQ-28)
EXIT=0
```

All 8 checks green against live AWS.

### Typecheck
`python3 -m py_compile acdl_platform/contract_resolver.py acdl_platform/outbox_writer.py adapters/terraform/adapter.py && bash -n scripts/run_spike_e2e.sh scripts/verify_phase10.sh` → **TYPECHECK OK**.

### Resolver cross-check
`python3 acdl_platform/contract_resolver.py contracts/spike.yaml /tmp/p10_ir.json` → emits an IR instance that **validates against `schemas/ir.schema.json`**. Stack `{name: l2-static-asset, kind: l2, depth: 1}`, 1 resource `s3` (type `aws:s3:bucket`, module `l1-s3@1.0.0`), 1 relationship (root→s3, parent).

### Adapter cross-check
Running the adapter against the resolved L2 IR emits `main.tf` with `resource "aws_s3_bucket" "s3"` + the backend key `spike/l2-static-asset/terraform.tfstate` (derived from the stack name per D-P10-1). ✅

### E2E pipeline (Wave 5, real AWS)
`run_spike_e2e.sh` exits 0 and prints:
- `terraform plan OK (1 to add, 0 to change, 0 to destroy expected)` — real AWS plan succeeds.
- `checkov: 6 failed, 5 passed` → `PolicyCheckResult: 12 record(s)` (incl. ACDL_TAG_NAMING SKIPPED per D-043).
- `confidence: score=0.8 band=pass` (dev threshold ≥ 0.50).
- `outbox: contractId= 11111111-... hash= 6e4711b9...` — DynamoDB `put_item` to `acdl-outbox`.
- Final line: `=== SPIKE E2E OK ===`.

Outbox query (`verify_phase10.sh` Check g): `Count=4` (spike has been run multiple times; new events accumulate — append-only outbox, RPO=0, GENESIS chain for each).

---

## Layer 3 — Security: PASS

### No credentials committed in v1.1.4..v1.1.5

`git log v1.1.4..v1.1.5 --name-only` shows only:
- `.ciagent/PLAN.md`, `.ciagent/REQUIREMENTS.md`, `.ciagent/ROADMAP.md`, `.ciagent/VERIFY.md` (P09 narrative)
- `.gitignore` (P1-2 fix)
- the 9 Phase 10 deliverable files
- `terraform/spike/terraform.tf` (regenerated backend config — bucket name is the state bucket ARN, not a credential)

No `.env*`, no `*.tfstate`, no `*_key*`, no `tfplan`, no `.terraform.lock.hcl` (the latter is gitignored via line 14).

### AKIA scan
`git log v1.1.4..v1.1.5 -p | grep -iE "AKIA[A-Z0-9]{16}" | grep -v "^#"` returns matches only inside `.ciagent/VERIFY.md` (the **Phase 09** verify narrative — `AKIAYOZHMKZ7RK26N66W` the rotated spike key id and `AKIAYOZHMKZ772SINHFX` the deactivated root key id, both already flagged as P1-1 in the P09 verify). These are **access key IDs (public identifiers), not secret access key pairs** — and they live in the `.ciagent/` audit narrative, not in any executable code path. None of the Phase 10 deliverable files (9 files + regenerated TF) contain any `AKIA…` or `aws_secret…` string.

**P10-specific AKIA check:** scanned the 9 deliverable files + regenerated TF for `AKIA[A-Z0-9]{16}` and `aws_secret_access_key`/`secret_key` — **no matches**. Clean.

### .env.secrets
- `git check-ignore .env.secrets` → `.env.secrets` (gitignored). ✅
- File holds only the **spike user** key (`ACDL_AWS_ACCESS_KEY_ID`, `ACDL_AWS_SECRET_ACCESS_KEY`, `AWS_DEFAULT_REGION`); the root key id is **absent** (deactivated per D-034 in Phase 08).

### No long-lived credential in generated Terraform
`grep -rn --exclude-dir=.terraform -E "AKIA|aws_secret" terraform/spike/main.tf terraform/spike/terraform.tf terraform/spike/providers.tf acdl_platform/ contracts/ modules-ir/` → **no matches**. The generated TF references only the state bucket name (`acdl-tfstate-581513795199-us-east-1`) — a bucket name, not a credential.

### Outbox write is append-only
`grep -c "delete_item\|update_item" acdl_platform/outbox_writer.py` → **0**. Only `put_item` is called (D-P10-3 single event; GENESIS → one event; append-only).

### E2E runner is plan-only
`grep -c "terraform apply" scripts/run_spike_e2e.sh` → **0**. The runner calls `terraform init + validate + plan` only (spike scope; apply gated by HITL in v1.2 per the Out-of-Scope table).

---

## Layer 4 — Quality: PASS

### README layout
README's layout table still matches reality: `acdl_platform/`, `schemas/`, `adapters/`, `terraform/`, `modules-ir/` all populated and described accurately. `modules-ir/` row notes `l1-s3` + `l2-static-asset` (Phase 09–10). ✅

### Commit ci-blocks
All 8 Phase 10 commits (798f430 prep, cc4c27c plan, 8437a51 Wave 1, 622abe0 Wave 2, 7afaa34 Wave 3, e29319a Wave 4, d3aa960 traceability, 35a336a ship) carry `---ci---` blocks with `project/phase/milestone/status/persona/tasks` (or `release.tag` for the ship commit). ✅

### Roadmap + Requirements
- `ROADMAP.md` Phase 10 → `Status: complete (v1.1.5)`. ✅
- `REQUIREMENTS.md` traceability: REQ-25/27/28 → `complete (v1.1.5)`. ✅

### L2 README internal consistency
`modules-ir/l2/l2-static-asset/README.md` accurately explains D-P10-1 (the adapter consumes the resolved IR; for depth-1, the L2 root module IS the L1's resource — no separate module block; relationships ignored at TF level for the spike). References `l1-s3` only. ✅

### Spike scope vs v1.2 boundary (D-P10-1/2/3)
- **D-P10-1:** L2 composition is depth-1, one child, wires passthrough. The adapter's backend key now derives from the stack name (spike/l2-static-asset/terraform.tfstate). ✅
- **D-P10-2:** The contract is YAML (`contracts/spike.yaml`); the resolver parses YAML → dict → validates against `schemas/contract.schema.json` (JSON Schema draft 2020-12). ✅
- **D-P10-3:** The evidence event is a **single** `CONFIDENCE_COMPUTED` event with `prev_event_hash=GENESIS`. The chain is GENESIS → this event (one link). ✅

### REQ-28 (the binding spike claim)
Re-confirmed via the in-repo substrate-agnostic scan:
- `grep -rn --include='*.py' -E 'aws_s3_bucket|aws_[a-z]+_[a-z]+' acdl_platform/` → **no matches** (platform Python is substrate-agnostic).
- Python scan of `modules-ir/` JSON for `aws_*` resource-type **values** (excluding `description`/`$comment` strings, which may legitimately reference the mapping to explain it) → **CLEAN**.
- `adapters/terraform/adapter.py` DOES contain `aws_s3_bucket` (in `TYPE_MAP` + resource emission) — as it must; it is the only substrate-specific code. ✅

`verify_phase10.sh` Check (h) prints:
> ok: REQ-28: adapter is the only substrate-specific code; modules-ir/ + acdl_platform/ are substrate-agnostic (docs/comments excluded)

**The spike's central proof holds.** The IR commitments are intact: no polyglot mess.

## Requirements coverage

| REQ | Phase | Plan claim | Verified | Status |
|-----|-------|------------|----------|--------|
| REQ-25 | 10 | T-10.1/2/3 | composition.json + registry + README present + shape correct | **covered** |
| REQ-27 | 10 | T-10.4/5/6/7/8 | contract + resolver + adapter + outbox + e2e runner; full pipeline runs end-to-end against real AWS | **covered** |
| REQ-28 | 10 | T-10.9 | verify_phase10.sh Check (h) passes; adapter is the only substrate-specific code | **covered** |

---

## Integration links

- `contract_resolver.py` imports `yaml` + `jsonschema` (both available); loads `schemas/contract.schema.json`, `modules-ir/registry.json`, `modules-ir/l2/l2-static-asset/composition.json`, `modules-ir/l1/l1-s3/interface.json`, `schemas/ir.schema.json` — all resolve.
- `adapter.py` imports stdlib only; consumes the IR instance shape emitted by the resolver (`stack`, `resources[].{id,type,inputs,outputs,nfrs}`). ✅
- `outbox_writer.py` imports `boto3` (available); writes to `acdl-outbox` (Phase 08 table). ✅
- `run_spike_e2e.sh` calls `contract_resolver.py` → `adapter.py` → `terraform` → `checkov` → `checkov_adapter.py` → `acdl_platform.confidence_signal` → `outbox_writer.py`. All imports + paths resolve. ✅
- `verify_phase10.sh` calls `run_spike_e2e.sh` (Check e), queries DynamoDB (Check g), greps the repo (Check h). All paths resolve. ✅

---

## P0 / P1 issues

**P0: none.**

**P1: none new to Phase 10.** The P1-1 from Phase 09 (two AWS access key IDs — `AKIAYOZHMKZ7RK26N66W` + `AKIAYOZHMKZ772SINHFX` — appearing in the `.ciagent/VERIFY.md` Phase 09 narrative) is **carried forward, not introduced here**. These are public key identifiers (not secret pairs) and live in the `.ciagent/` audit narrative, not in executable code. Recommended for a future hygiene redaction pass; non-blocking for v1.2 ship.

---

## Final verdict

**Phase 10: VERIFIED**

The milestone capstone is genuinely achieved:
- (a) `l2-static-asset` references `l1-s3` only (depth 1). ✅
- (b) One contract submission (`contracts/spike.yaml`) completes the full pipeline end-to-end (resolve → IR → terraform plan against real AWS → Checkov → confidence `pass` → DynamoDB outbox write). ✅
- (c) `verify_phase10.sh` proves the adapter is the only substrate-specific code (REQ-28). ✅
- (d) Evidence event written to the DynamoDB outbox (RPO=0, GENESIS chain). ✅

The IR commitments hold. Ready for the COMPLETE gate → review → ship `v1.2.0` → audit.
