## Layer 1: Structural — PASS ## Structural
- All 8 plan-referenced files exist on disk (`core/regression_verify.py`, - `core/policy_engine.py` exists, implements `PolicyEngine` Protocol
`core/local_emulators.py`, `scripts/run_regression.sh`, (PEP 544, `@runtime_checkable`), `PolicyEngineRegistry` with
`tests/test_verify_regression_mode.py`, `register()` + `get_engine()`, `NullEngine` fallback.
`tests/test_local_emulating_adapters.py`, - `adapters/kyverno-json/kyverno_json_engine.py` exists, exports
`.ciagent/CAPABILITY_INVENTORY.md`, `REGRESSION_REPORT.md`, `KyvernoJsonEngine` with `name`, `is_configured()`, `evaluate()`.
`REGRESSION_REPORT.json`). - `adapters/kyverno-json/__init__.py` loads the engine by file path
- All imports resolve (`py_compile` + runtime import OK). (the dir name has a hyphen — not a valid Python package name).
- No TODO/FIXME/HACK/stub placeholders in new code (the `LocalLambdaStub` - `adapters/kyverno-json/policies/_smoke.json` exists (trivial policy
is a legitimate local emulator, not a placeholder). for round-trip validation).
- All declared exports exist (`run_regression`, `write_report`, - `scripts/install-kyverno-json.sh` exists (go install kj@latest).
`CAPABILITY_REGISTRY`, `RegressionReport`, `CapabilityResult`, - `.ciagent/config.json` has the `policy` object
`FlatFileOutbox`, `LocalEcsEmulator`, `LocalS3StateBackend`, (`engine: kyverno-json`, `policy_root`).
`LocalLambdaStub`, `run_local_e2e`, `is_local_tier`). - `.gitea/workflows/ci.yml` + `.github/workflows/ci.yml` have the
Go + kj install step (best-effort, tests skip when kj absent).
- `tests/test_policy_engine.py` (10 tests) +
`tests/test_kyverno_json_engine.py` (16 tests) exist.
## Layer 2: Behavioral — PASS ## Behavioral
- `pytest tests/ -m "not slow"`: **513 passed**, 5 deselected. - `pytest tests/test_policy_engine.py tests/test_kyverno_json_engine.py`:
- `pytest tests/ -m slow`: **5 passed** (2 local E2E + 3 regression **24 passed, 2 skipped** (kj not installed — expected;
integration incl. live-AWS terraform plan). `pytest.skip("kj not installed")`).
- **Total: 518 passed, 0 failed.** - `NullEngine` satisfies the `PolicyEngine` Protocol (G-Q8a —
- Requirement coverage: REQ-112 (P52), REQ-113 (P53), REQ-114 (P54), `isinstance(NullEngine(), PolicyEngine)` is True). Proves the swap
REQ-115 (P55) — all 4 marked `complete`. boundary is real without implementing OPA.
- Regression gate: `bash scripts/run_regression.sh` → **16/16 - `KyvernoJsonEngine.is_configured()` returns `False` when
capabilities Verified** (12 local + 4 live-AWS). Milestone gate open. `which kj` is absent → `evaluate()` returns a single
`KJ_ENGINE_NOT_CONFIGURED` SKIPPED PCR (distinct `ruleId` from
NullEngine's `NULL_ENGINE_INACTIVE` — G-Q4).
- PCR records validate against `schemas/policy_check_result.schema.json`
(via `jsonschema.validate` in tests).
- Defensive parsing: malformed kyverno-json output → `error` PCR
(`KJ_ENGINE_ERROR`), never an exception.
- Severity annotation reading (G-Q10a): policies with
`nova.cloudinit.dev/severity: high` produce PCRs with `severity: high`;
policies without the annotation default to `info`.
- Registry: `get_engine()` returns the configured engine; unknown
engine name raises `KeyError`; `policy` key absent → `NullEngine`.
- No regression: `pytest tests/test_confidence_signal.py
tests/test_adapter.py tests/test_checkov_adapter.py
tests/test_kyverno_adapter.py tests/test_contract_resolver.py` —
**132 passed** (unchanged).
## Layer 3: Security (STRIDE) — PASS ## Security
| Threat | Risk | Disposition | - No new secrets, no new network calls in the engine core (the engine
|--------|------|-------------| shells to a local binary; the binary makes no network calls for
| Spoofing | Local Lambda stub patches `_get_dynamodb`/`_get_secrets_client`; opt-in via `ACDL_LOCAL_TIER=1`, never in prod | Accept (low) | `scan`).
| Tampering | Flat-file outbox hash-chain verification detects tampering | Accept (low) | - `is_configured()` guard ensures the platform runs without the binary
| Repudiation | Regression report records per-capability status + timestamps | Accept (low) | (no hard dependency that could be exploited as a DoS vector).
| Info Disclosure | Creds read into env vars, never logged (0 cred strings in reports); ECS binds 127.0.0.1 only | Accept (low) | - The engine writes the payload to a temp file (`tempfile.NamedTemporaryFile`)
| Denial of Service | Local ECS emulator: free port, daemon thread, clean destroy | Accept (low) | and unlinks it in a `finally` block (no leftover payload on disk).
| Elevation of Privilege | `urllib.urlopen` patched to fake response (no network egress); no eval/exec/subprocess in adapter | Accept (low) | - No `shell=True` in the `subprocess.run` call (command is a list —
no shell injection surface).
All threats low-severity; auto-accepted per ## Quality
`config.json security.auto_accept_low_severity=true`.
## Layer 4: Quality (multi-persona) — PASS - `python3 -m py_compile` passes on all new Python files.
- The `PolicyEngine` Protocol is minimal (3 members) — the swap
boundary is the moat (NORTH_STAR Strategic Objective #2).
- The `NullEngine` proves a second implementation exists (structural
conformance) — the OPA swap is a known quantity (RESEARCH §4.2).
- Tests use `pytest.skip` when `which kj` is absent, so the CI matrix
passes with or without the binary (the suite is green in both cases).
| Persona | Finding | Verdict | ## Must-have checklist
|---------|---------|---------|
| Correctness | 7 adapter defects fixed; each traceable to a terraform validate/plan error | PASS |
| Testing | 518 tests pass; 24 new tests. P2: uptime-kuma + RDS not in registry | PASS (1 P2) |
| Security | No creds logged; loopback-only; monkey-patches scoped to local tier | PASS |
| Performance | Regression run ~60s; acceptable for a milestone gate | PASS |
| Maintainability | Well-structured; adding a capability = 1 function + 1 registry entry | PASS |
| Adversarial | Gate can't be bypassed; local E2E can't mutate cloud; no injection vectors | PASS |
**0 P0, 0 P1, 1 P2 (post-hoc: expand regression registry to uptime-kuma + RDS stacks).** - [x] `PolicyEngine` Protocol + `PolicyEngineRegistry` + `NullEngine`
(REQ-291)
- [x] `config.json.policy` object (REQ-292)
- [x] `KyvernoJsonEngine` adapter (REQ-293)
- [x] `__init__.py` + `_smoke.json` + `install-kyverno-json.sh` + CI
install (REQ-294)
- [x] `test_policy_engine.py` — protocol conformance, registry,
NullEngine fallback (REQ-308)
- [x] `test_kyverno_json_engine.py` — PCR schema validity, defensive
parsing, skip-without-kj (REQ-309)
## Verdict **Verdict: PASS** — all P1 must-haves met, no regressions, 24 new
tests pass (2 skip-without-kj), 132 existing tests unchanged.
**VERIFY PASS** — all 4 layers pass. The v1.10 milestone is sound:
the pipeline regression gap is fixed (D-091), the platform is fully
locally testable (D-092), every advertised capability is re-verified
(D-093, 16/16 Verified), and the docs/decks match verified reality
(D-094). 518 tests pass; the regression gate covers 16 capabilities
including 4 live-AWS checks. 0 P0, 0 P1, 1 P2 post-hoc. Ready to ship.

# ACDL — Verify (grill deliverable, commit ac11c01)
> Verify date: 2026-07-27. Verifier: ci-verifier. Scope: the grill
> deliverable (`.ciagent/GRILL.md`, phase 0, status `grill`) added in
> commit `ac11c01` since the v1.10 audit PASS (`ab477b3`). Docs-only;
> no code, no tests, no schema changes.
## Layer 1: Structural — PASS
- `.ciagent/GRILL.md` exists on disk (18250 bytes).
- No imports to resolve (markdown docs file).
- No TODO/FIXME/HACK/stub placeholders in the report.
- All required sections present per grill workflow Step 5 format:
title, Run header, Verdict, 9 axes (1–9), Meta, Binding Decisions
table (12 rows), Escalations section (2 entries: G-005, G-008).
- Commit `ac11c01` `---ci---` block is well-formed: `project: acdl`,
`phase: 0`, `milestone: v1.10`, `status: grill`, 12 decision ids
(G-001..G-012), 2 escalation lines.
## Layer 2: Behavioral — PASS
- `pytest tests/ -m "not slow"`: **513 passed**, 5 deselected (no
regressions introduced by the docs-only grill commit).
- No new tests required (docs-only deliverable; the grill is a
review artifact, not a code change).
- Requirement coverage: not applicable (phase 0, status `grill`; no
REQ-IDs bound to this deliverable). The grill's binding decisions
(G-001..G-012) are advisory and do not modify REQUIREMENTS.md per
grill workflow Step 7.
## Layer 3: Security (STRIDE) — PASS
| Threat | Risk | Disposition |
|--------|------|-------------|
| Spoofing | N/A (docs-only; no auth surface) | Accept (none) |
| Tampering | Grill report is git-tracked; tampering = git history rewrite (out of scope) | Accept (low) |
| Repudiation | Commit `ac11c01` signed by author; `---ci---` block records status + decisions | Accept (low) |
| Info Disclosure | No credentials, keys, tokens, or PII in the report (grep scan clean) | Accept (low) |
| Denial of Service | N/A (docs file; no runtime surface) | Accept (none) |
| Elevation of Privilege | N/A (docs-only; no privilege surface) | Accept (none) |
All threats low-or-none; auto-accepted per
`config.json security.auto_accept_low_severity=true`.
## Layer 4: Quality (multi-persona) — PASS
| Persona | Finding | Verdict |
|---------|---------|---------|
| Correctness | 12 binding decisions traceable to evidence (commit/file/req-id); 2 escalations correctly unresolved | PASS |
| Testing | Docs-only; 513 fast tests pass (no regression) | PASS |
| Security | No credential leakage; no sensitive data in report | PASS |
| Performance | N/A (docs file; no runtime cost) | PASS |
| Maintainability | Report follows grill workflow Step 5 format exactly; appendable for future runs | PASS |
| Adversarial | Escalations (G-005, G-008) are surfaced, not silently skipped; visible via `ciagent audit` | PASS |
**0 P0, 0 P1, 0 P2.**
## Verdict (grill deliverable)
**VERIFY PASS** — all 4 layers pass. The grill deliverable is a
well-formed docs-only artifact. 513 fast tests pass (no regression).
No credential leakage. 12 binding decisions recorded; 2 escalations
(G-005 risks, G-008 budget) correctly surfaced for human resolution.
The grill does not modify PROJECT.md, ROADMAP.md, or REQUIREMENTS.md
(per grill workflow Step 7).
