core/env.py dual-read helper (D-108); 21 ACDL_*→NOVA_* env vars migrated across core/scripts/adapters/tests/workflows + .env/.env.secrets (key rename, values stay). G-106 binding: run_platform.sh:288-289 + regression_verify.py:309-312 dual-read (NOVA first, ACDL fallback). G-108 binding: Gitea NOVA_* secrets created via API + workflow secrets: refs updated (deploy.yml + modules-lifecycle.yml, .gitea + .github). acdl_tagging.py→nova_tagging.py (D-109 warn mode, nova:* enforced). .acdl/→.nova/ consumer path (resolver + deploy workflow + schema + tests + docs). Test fixtures updated; pytest + run_ci.sh PASS. ---ci--- project: acdl phase: 2 milestone: v1.15 status: execute ---/ci---
ACDL Adapters
Overview
Adapters translate the engine-agnostic Target Stack IR to engine-specific formats. The Terraform adapter is the primary adapter (IR → HCL). Policy adapters translate security tool output into normalized PolicyCheckResult records that the confidence signal consumes in an engine-agnostic way.
Existing Adapters
| Adapter | Path | Input | Output | Purpose |
|---|---|---|---|---|
| Terraform adapter | adapters/terraform/adapter.py |
Stack instance JSON | Terraform HCL (main.tf, terraform.tf, providers.tf) |
Compiles IR to Terraform |
| Checkov adapter | adapters/terraform/policy/checkov_adapter.py |
Checkov JSON | PolicyCheckResult records |
Translates Checkov results |
| Wiz adapter | adapters/wiz/wiz_adapter.py |
Wiz API issues JSON | PolicyCheckResult records |
Translates Wiz security findings |
| Kyverno adapter | adapters/kyverno/kyverno_adapter.py |
Kyverno PolicyReport JSON | PolicyCheckResult records |
K8s-native policy translation |
How to Write an Adapter
Terraform Adapter Extension
- Add a stack type → Terraform type mapping to
TYPE_MAP. - Add non-identity input mappings to
INPUT_MAP. - Add non-identity output mappings to
OUTPUT_MAP. - Add a specialized
_emit_resourcebranch if the resource needs nested blocks (e.g. inline policies, rule sets).
Policy Adapter Pattern
- Define
SEVERITY_MAPandRESULT_MAPdicts that translate the engine's native severity/result vocabulary to thePolicyCheckResultenums. - Implement
_to_pcr(raw_record, contract_id)→PolicyCheckResultdict. - Implement
adapt(input_path, contract_id)→ list ofPolicyCheckResultdicts. - Implement
is_configured()→ bool (env var check) so the platform can skip the adapter when credentials are absent.
How to Wire an Adapter
- Terraform adapter — invoked by
scripts/run_platform.shStep 3 (terraform-plan). - Checkov adapter — invoked by
scripts/run_platform.shStep 5 (checkov). - Wiz / Kyverno adapters — optional Steps 5b/5c, run only when the relevant env vars are set.
- All policy adapters output records that are validated against
schemas/policy_check_result.schema.json.
Dependencies
jsonschema,pyyaml— used by all adapters for loading and validating inputs.boto3— used by the Wiz adapter for AWS API access.checkov— used by the Checkov adapter to run policy scans.- No external deps for the Terraform adapter (pure Python).
How to Test Adapters
tests/test_adapter.py— Terraform adapter (TYPE_MAP, resource emission, refs, outputs).tests/test_checkov_adapter.py— Checkov adapter.tests/test_wiz_adapter.py— Wiz adapter.tests/test_kyverno_adapter.py— Kyverno adapter.- All adapter tests load fixtures from
tests/fixtures/and usemotofor AWS mocking.
Where to Write Tests
tests/test_<adapter_name>.pypaired withtests/fixtures/<adapter>_fixture.json.
Adding a New Adapter
- Create
adapters/<name>/<name>_adapter.py. - Implement
adapt()and (for policy adapters)is_configured(). - Add the adapter's engine name to the
engineenum inschemas/policy_check_result.schema.jsonif it is a policy adapter. - Write a test (
tests/test_<name>_adapter.py) plus a fixture (tests/fixtures/<name>_fixture.json). - Add it to
scripts/run_platform.shif it is invoked at runtime. - Update this README.
