Jon Chery fda4564a7f feat(P58): single platform VPC + deterministic env-aware state keys

EXECUTE stage. Fixes the 4-VPC bug: adds a single shared VPC to
terraform/platform, drops the vpc child from the microservice composition
(references the platform VPC via data source), and makes state keys
env-aware (spike/{id}/{env}/terraform.tfstate — stable across lifecycle).

Platform VPC (terraform/platform/main.tf):
- aws_vpc.acdl_shared (10.0.0.0/16) + 2 subnets + IGW + route table + SG
- Outputs: vpc_id, subnet_ids, ecs_security_group_id

Microservice composition (modules/l2/microservice/composition.json):
- Dropped the vpc child (no per-contract VPC ever again).
- Added data_sources block: platform_vpc → terraform_remote_state (platform).
- Wires: vpc.outputs.subnet_ids → platform_vpc.outputs.subnet_ids.
- Wires: platform_vpc.outputs.vpc_id → alb.inputs.vpc_id.
- Wires: platform_vpc.outputs.ecs_security_group_id → service.inputs.security_group.

Contract resolver (core/contract_resolver.py):
- Added environment to the stack instance (stack.environment).
- Added data_sources handling: pseudo-children with outputs but no resources.
- data_sources propagated through fragment merge to the final stack instance.

Adapter (adapters/terraform/adapter.py):
- State key: spike/{stack_name}/{environment}/terraform.tfstate (env-aware).
- Emits data "terraform_remote_state" "platform" block when data_sources present.
- ref:platform_vpc.<output> → data.terraform_remote_state.platform.outputs.<output>.

Tests (tests/test_adapter.py):
- test_adapt_env_aware_state_key: spike/msvc/prod/terraform.tfstate.
- test_adapt_emits_data_source_block: data.terraform_remote_state.platform.
- test_adapt_no_vpc_for_microservice: no resource "aws_vpc" in microservice output.
- Updated existing state key assertion (spike/s3/dev/terraform.tfstate).

Regression: 467 passed, 0 skipped, 5 deselected. run_platform.sh --check-only
passes for both microservice (9 resources, no VPC) and static-assets (5 resources).

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_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.
