Jon Chery e1be05287b feat(P39): refresh design docs + parameterize adapter (P1-1)

---ci---
project: acdl
phase: 39
milestone: v1.9
status: execute
---/ci---

Phase 39 — design-doc-refresh-and-p1-1-parameterization:

Design docs (REQ-100, REQ-101):
- hitl_matrix_design.md: 'dev-only spike'/'v1.2 wires the gates' framing
  replaced with v1.9 wired-gates reality; 8-concern matrix marked
  implemented (offline-testable subset + signed evidence artifacts,
  D-084); v1.9 wiring section cross-references hitl_gates.py +
  attestation_matrix.py; approver_dr noted.
- audit_ledger_design.md: outbox marked shipped+production since v1.8;
  S3 Object Lock + JWS + async worker + DLQ + daily checkpoints clearly
  labeled 'Deferred to a future milestone (D-083)'; RPO/RTO table updated;
  approver fields note v1.9 hitl_gates.attest.

P1-1 adapter parameterization (REQ-102, D-085):
- ecs-service interface.json: desired_count (default 1), launch_type
  (FARGATE), family (app) inputs added.
- alb interface.json: load_balancer_type (application), target_type (ip).
- adapter.py: hardcoded defaults replaced with inputs.get(<name>, <default>);
  hardcoded 'acdl-microservice-rt'/'acdl-microservice-igw' Name tags
  derive from the VPC name input.
- contract_resolver.py: child_input_map routes wires to the sub-resource
  that declares the input (desired_count → aws:ecs:service, family →
  aws:ecs:task_definition, target_type → targetgroup, etc.).
- microservice composition.json: wires added for the new inputs.

Tests: +21 (test_p1_1_adapter_parameterization.py, test_design_docs_current.py).
371 passed; run_ci.sh green; run_platform.sh --check-only green; v1.1 S3
regression preserved.

ACDL Adapters

Overview

Adapters translate the substrate-agnostic Target Stack IR to substrate-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_resource branch if the resource needs nested blocks (e.g. inline policies, rule sets).

Policy Adapter Pattern

Define SEVERITY_MAP and RESULT_MAP dicts that translate the engine's native severity/result vocabulary to the PolicyCheckResult enums.
Implement _to_pcr(raw_record, contract_id) → PolicyCheckResult dict.
Implement adapt(input_path, contract_id) → list of PolicyCheckResult dicts.
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.sh Step 3 (terraform-plan).
Checkov adapter — invoked by scripts/run_platform.sh Step 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 use moto for AWS mocking.

Where to Write Tests

tests/test_<adapter_name>.py paired with tests/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 engine enum in schemas/policy_check_result.schema.json if 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.sh if it is invoked at runtime.
